Why We Still Need Innovation in Successful Clean Energy Technologies

Today is my last day at CFR. I’m joining ReNew Power, India’s largest renewable energy firm, as their CTO. I’m excited for a new adventure but sad to leave the Council, which has given me support and autonomy to study the innovations needed for global decarbonization. Read More

Moving On
This is my last post on this blog. I start a job on Tuesday on the National Economic Council Staff; blogging isn’t part of the portfolio. When I started this blog six years ago, I never imagined it would become such an important part of my professional life. It’s been gratifying to know that there’s an audience for analysis-driven blogging on energy and climate from an independent point of view. And it’s been a treat to engage with readers. Varun Sivaram will be taking over the blog. If you haven’t been reading his stuff, you should. Two years ago, had I left the Council, I suspect I would have closed the blog down. But Varun is true to this blog’s mission, and it’s comforting, as I shift from blog author to blog reader, to know that it’s in good hands.

Why the United States Should Respond to Oil Price Volatility By Reducing Oil Consumption
This post is co-authored by Sagatom Saha, research associate for energy and foreign policy at the Council on Foreign Relations. Read the report from a recent CFR workshop on oil price volatility. The workshop, hosted by Michael Levi and Varun Sivaram, was made possible by the support of the Alfred P. Sloan Foundation. Last month, CFR’s Greenberg Center for Geoeconomic Studies convened a workshop to discuss the causes, consequences, and policy implications of oil price volatility. Most of the roughly forty experts in attendance agreed that volatility—which the workshop defined as price swings in either direction of up to a year—will persist for the foreseeable future. They also broadly agreed that at least some instances of volatility have serious economic and geopolitical consequences. But when it came to proposing policy measures to reduce volatility, controversy replaced consensus; few participants rallied around any recommendation, warning of side effects from trying to manage oil prices. In fact, the only policy recommendations that did attract widespread support were ones that reduced the U.S. economy’s exposure to oil markets by lowering consumption, the only surefire way to decrease the risks from volatility. These discussions happened against the backdrop of a changing global energy landscape. In particular, participants reflected on future sources of “swing supply” to balance supply and demand and moderate oil price volatility. Uncertainty over whether Saudi Arabia has abdicated its historical role as swing supplier and if U.S. shale oil can instead play that role suggests that there is no end to volatility in sight. But, as the workshop report notes, “Given Saudi Arabia’s large spare production capacity—still the world’s biggest—most workshop participants still see the kingdom playing some role as the producer of last resort.” Figure 1 from the report on CFR’s oil price volatility workshop Having established that volatility is likely to persist, the workshop explored its economic and geopolitical consequences at home and abroad. Although the academic literature more commonly focuses on the effects of oil price levels—i.e., high or low oil prices—participants honed in on the effects of price volatility independent of price level. The workshop report elaborates: Even low [oil] prices, if paired with volatility, do not necessarily lead to an economic boost [in the United States], some participants suggested. Fluctuating prices can make consumers wary of spending, thus dampening any stimulus effect of lower oil prices. …For oil-exporting countries, some participants noted that price volatility, more than the price level, is particularly problematic. That is because, as one participant put it, it is easier to build a budget that works with oil at $50 per barrel than one that works when oil zooms between $20 and $80 a barrel. But participants were hard-pressed to provide recommendations to U.S. policymakers for how to reduce the volatility of global oil prices. For example, Columbia’s Jason Bordoff wrote a post for this blog arguing that the United States should not use its Strategic Petroleum Reserve (SPR) as a “Federal Reserve of Oil” to buffer global price volatility on a regular basis. Such a strategy would have grave side effects, including muting price signals to producers and consumers and depleting the SPR, impairing its intended ability to counteract major oil market disruptions. The workshop also explored ways to reduce the elasticity of oil supply and demand—at least theoretically, more price-responsive demand and supply should reduce price volatility. But targeting elasticity can yield impractical policy proposals, like taxes on producers that increase as their production decreases. And some policies that enjoy broad support, like U.S. fuel economy standards, might actually be undesirable if evaluated only by the effect on demand elasticity: Efficiency standards that make the automobile fleet cleaner can actually end up decreasing elasticity and increasing oil price volatility, one participant noted. If cars get better mileage, gasoline prices will matter less to drivers, and consumers will not cut down consumption. Even if more efficient U.S. cars can increase oil price volatility, the effect is likely washed out by the salutary effects of consuming less oil. (Indeed, we recently studied U.S. fuel economy standards and found that the benefits far outweigh the costs.) This does not mean that reducing U.S. oil consumption will mitigate all of the risks of oil price volatility—around the world, volatility still threatens U.S. economic and geopolitical interests. And it is not always a bad idea to try and increase elasticities—the United States should advocate for global reform of fuel subsidies that can insulate major economies from the price signals of oil markets. But to reduce the effects of oil price volatility on the U.S. economy, it is likely best to reduce U.S. exposure to the global oil market rather than attempt to tame it.

The Strategic Petroleum Reserve: A Policy Response to Oil Price Volatility?
This guest post is authored by Jason Bordoff, professor of professional practice and founding director of the Center on Global Energy Policy at Columbia University’s School of International and Public Affairs. For more on the causes, consequences, and policy implications of oil price volatility, read the report from a recent CFR workshop. Oil price volatility—sharp price swings in either direction over a short timespan—can harm economies, provoke political instability, and exacerbate poverty. Moving forward, oil price volatility may increase if Saudi Arabia and the rest of OPEC continue to abstain from efforts to manage the market and hold very little spare capacity to cushion the price impact of global supply disruptions, and if the role of shale as a short-cycle source of supply remains uncertain, as Bob McNally argues in a forthcoming Center on Global Energy Policy book. Although few countries are capable of materially influencing global oil markets, CFR posed the question in a recent workshop whether the United States may be able to smooth the fluctuating price of oil by using its Strategic Petroleum Reserve (SPR), an emergency fuel storage of oil maintained by the United States Department of Energy. But just because the SPR can be used in this way does not mean that it should. In fact, policymakers should avoid using the SPR as a “Federal Reserve of Oil” that actively manages the market on an ongoing basis. This would mute important market price signals to consumers and producers, exceed the competence of U.S. authorities, and create pernicious political temptations to cushion consumers from high fuel prices. Rather, the United States should only use the SPR in infrequent circumstances to protect the U.S. economy from major supply disruptions around the world. What is the SPR? Congress created the SPR in the Energy Policy and Conservation Act (EPCA) of 1975 in the wake of the Arab Oil Embargo to insulate the United States from future petroleum supply disruptions. As a member of the International Energy Agency (EIA), the United States is required to hold stocks of crude oil and/or petroleum products equivalent to ninety days’ worth of net imports for use in an emergency. These stocks can be held either in private inventories or directly by the government. As of February, the SPR contained contains the equivalent of 137 days of net import cover. That figure has risen in recent years in response to both surging oil supply and lower oil demand, dramatically reducing the nation’s dependence on imports. Presently, the SPR holds 695 million barrels of crude oil, with capacity to hold 714 million barrels. EPCA defines the circumstances in which the SPR may be used. Generally, there are three possible types of drawdowns [1]: 1. Full drawdown: The president can order a full drawdown of the reserve to counter a "severe energy supply interruption." 2. Limited drawdown: Up to thirty million barrels if the president finds there is “a domestic or international energy supply shortage of significant scope or duration.” 3. Test sale or exchange: The secretary of energy is authorized to carry out test drawdowns and distribution of crude oil from the SPR not to exceed five million barrels. The New Oil Market Means the SPR Serves a Different Purpose However, the EPCA drew up the SPR under a very different reality than today’s. In the 1970s, oil price controls existed in the United States, and most internationally traded oil was sold under long-term contracts. As a result, a disruption in contracted shipments could result in a physical shortage for the buyer because neither strategic and commercial stockpiles nor a large spot market existed at the time. In the intervening years, the oil market has become the largest and most liquid commodity market on earth with vibrant futures markets. Almost all oil is globally traded for a price indexed to benchmark crude prices and mature pricing hubs in regions including Europe (Brent), the United States (WTI), and the Middle East (Dubai).[2] Given how the oil market has changed, the consequence of a supply disruption anywhere is a price increase everywhere. Hence, the risk against which the SPR needs to guard today is global. A supply disruption from anywhere causes domestic prices to spike regardless of whether U.S. refineries import from the disrupted countries. The effect on prices of such a disruption can be tempered by additional supply released from strategic stocks through coordinated action by countries, as well as by commercial supplies and spare capacity. An increasingly important role for SPR policy may also be managing market expectations.[3]  Markets react very quickly to anticipated supply and demand changes, which can sharply affect price movements. In 2012, for example, the effect on the world oil price of sanctions on Iranian oil sales and other geopolitical fears was tempered, at least in part, by a perception in the market that the United States and other IEA members might release stocks from the SPR if prices rose too far.[4] In the summer of 2012, both the G-20 and G-7 issued statements intended to signal that they might tap strategic oil stocks if necessary.[5] Policymakers sent other signals to this effect as well, such as the reported conversation in March 2012 between President Obama and Prime Minister David Cameron about using strategic oil stocks.[6] As a result, numerous analysts cautioned that the Obama Administration might release SPR crude if oil prices rose above roughly $120 per barrel. Should Policymakers Use the SPR To Mitigate Oil Price Volatility? The answer depends on the cause and duration of the volatility. For short-term price spikes due to supply disruptions, the use of strategic stocks can mitigate the concomitant economic harm until the market disruption is resolved. These disruptions may be driven by natural disasters like hurricanes or the recent wildfires in Canada, by geopolitical events like wars, or even domestic events like labor strikes. Such use of the SPR is consistent with the changes to the global oil market over the past forty years discussed above. In today’s market, the SPR needs to guard against the risk of a global disruption to crude supply that causes domestic prices to spike rather than supply cut-offs to particular importing refineries. Accordingly, the value of the SPR should be measured less by days of import cover than by the ability of the SPR to add supply to the global oil market to mitigate the economic harm of disruptions. Consistent with this approach, the Quadrennial Energy Review recommends updating the EPCA’s usage guidelines for use of the SPR in the following ways: 1. The definition of a "severe energy supply interruption"—in the event of which EPCA authorizes releases of stocks from the SPR—should include any disruption in the global oil market likely to cause a severe increase in the price of petroleum products, regardless of whether the United States would experience lower oil imports. 2. The President should have the authority to release stocks from the SPR if a severe price increase will likely result from an emergency situation, rather than having to wait until a severe fuel price increase has already occurred. To be effective, the SPR’s infrastructure needs to be modernized, because today it may no longer be able to deliver additional and incremental barrels to the market to address supply disruptions.[7] To ensure SPR crude oil can be effectively accessed in a future supply disruption, the Quadrennial Energy Review estimated that $1.5 to $2 billion is needed “to increase the incremental distribution capacity of the SPR by adding dedicated marine loading dock capacity at the Gulf Coast terminus of the SPR distribution systems, as well as undertaking a life extension program for key SPR components.” By contrast, it would be unwise for the federal government to use the SPR as a “Federal Reserve of Oil” on a regular basis—that is, to try to achieve stable oil prices at all times, even when the oil price volatility is not from short-term disruptions but rather from other structural supply and demand shifts. There are several reasons for this. First, perhaps most importantly, using government oil stocks to prevent price spikes and drops would mute the price signal to producers and consumers that would otherwise address the underlying supply and demand imbalance in the market. In response to high prices over the past decade, producers invested hundreds of billions of dollars in new sources of higher cost oil supply, including the investments and innovation that enabled U.S. shale revolution. Oil demand growth also slowed at the time as consumers responded to higher prices. But in response to the current price collapse, demand has rebounded, producers have slashed capital expenditures, and production is falling in the United States and other countries like China, Mexico and Colombia. By muting these price signals to consumers and producers, the SPR could slow the market’s ability to correct itself, risking a prolonged imbalance between supply and demand and depletion of the limited stocks in the SPR. Second, it is not clear whether the U.S. government (or any entity, for that matter) has the necessary expertise to ascertain the causes of near-term oil price volatility, assess the role of supply and demand dynamics vs. other factors like financial speculation, and understand the effects of geopolitical and market conditions in important producing countries. Leading market analysts consistently demonstrate their inability to predict price movements and often confess difficulty in explaining current market shifts. The U.S. government may have officials with experience analyzing the global oil market (as with the current Administrator of the EIA), but often that is not the case, especially among the political appointees making the ultimate decision about SPR use. Third, explicitly using the SPR to mitigate price volatility would likely lead to intense political pressure being brought to bear on policymakers to cushion high gasoline prices (conversely, producing states and firms may discourage policymakers from permitting very low prices, as in today’s environment). High gasoline prices, especially in an election year, often become hot-button issues and lead to calls to tap the SPR. Fourth, unless the US intends to manage the global markets only with its domestic SPR, it is unlikely that IEA countries can agree to release the SPR quickly enough to address short-term oil price volatility. We have seen examples of quick action in the past, such as after Hurricane Katrina, but also cases in which such coordination takes time. In 2011, for example, the Libyan civil war led to a disruption in oil supply in February, but the IEA-coordinated release did not occur until June, in large part due to the time necessary to build support among IEA member countries. In theory, this concern could be addressed by creating an international board to assess market conditions and make recommendations about strategic reserve use to mitigate volatility. Yet that would require (1) IEA members to agree that such use of strategic stocks was sensible; (2) the United States to cede decision-making authority to an international body, which would generate severe opposition; and (3) IEA countries that meet their strategic reserve requirements through private sector inventories, not government-held stocks, to overcome the challenge of coordinating private inventory releases. Fifth, at roughly 700 million barrels, the current SPR may well not be large enough to effectively mitigate oil price volatility in a global market that consumes about 95 million barrels of oil every day. It is unclear exactly how much additional supply would have had to be put on the market from 2011 to 2014 to keep prices at an “acceptable” level rather than in excess of $100 per barrel, but, depending on the extent of the market shortfall, the U.S. SPR could be run down rather quickly. This concern may be addressed by drawing on stocks in other IEA countries, and by building new mechanisms to coordinate stock releases with non-IEA countries that are now holding very large stockpiles, like China. Yet such a coordination mechanism, as noted in the prior point, would come at the expense of timeliness or U.S. autonomy. Sixth, any supply additions to mitigate oil price spikes could be offset by OPEC producers if they wanted to support higher prices. While the ability of OPEC to coordinate, or the willingness of Saudi Arabia to cut production on its own, seems lacking at present, it is possible that OPEC could yet try to reassert its role as a market manager. A Guard Against Global Disruption, Not the Federal Oil Reserve Oil price volatility is harmful to the macro economy and to consumers, and it may be more likely moving forward than in the past because of changes in the behavior of oil producing countries and the emergence of U.S. shale as a short-cycle source of oil supply. Given how the oil market has changed over the past several decades, the SPR today guards against a different risk than it did initially. In today’s market, the risk against which the SPR needs to guard is a global disruption to crude supply that causes domestic prices to spike rather than supplies being cut off to particular importing refineries. Whether the SPR should be used to mitigate oil price volatility depends on the cause and duration of the volatility. In the event of short-term price spikes due to temporary supply disruptions, the use of strategic stocks can mitigate the concomitant economic harm until the market disruption is resolved. By contrast, using the SPR on a regular basis to try to achieve more stable oil prices—a “Federal Reserve of Oil” model—would be ill-advised for many reasons. These include preventing consumers and producers from responding to structural supply and demand shifts; political, market expertise, and SPR governance limitations; and potential producer country responses. Appendix [8] The circumstances that might require the use of the Strategic Petroleum Reserve are defined in the Energy Policy and Conservation Act (EPCA).  Generally, there are three possible types of drawdowns envisioned in the Act: Full drawdown: The President can order a full drawdown of the Reserve to counter a “severe energy supply interruption.” EPCA defines this as “a national energy supply shortage which the President determines – a. is, or is likely to be, of significant scope and duration, and of an emergency nature b. may cause major harm on national safety or the national economy; and c. results, or is likely to result, from (i) an interruption in the supply of imported petroleum products, (ii) an interruption in the supply of domestic petroleum products, or (iii) sabotage or an act of God.” EPCA also states that a severe energy supply interruption “shall be deemed to exist if the President determines that – a. an emergency situation exists and there is a significant reduction in supply which is of significant scope and duration; b. a severe increase in the price of petroleum products has resulted from such emergency situation; and c. such price increase is likely to cause a major adverse impact on the national economy.” Limited drawdown: If the President finds that - a. a circumstance, other than those described [above] exists that constitutes, or is likely to become, a domestic or international energy supply shortage of significant scope or duration; and b.  action taken....would assist directly and significantly in preventing or reducing the adverse impact of such shortage" then the Secretary may drawdown and distribute the Strategic Petroleum Reserve, although in no case: 1) in excess of an aggregate of 30,000,000 barrels, 2) for more than 60 days, or 3) if there are fewer than 500,000,000 barrels....stored in the Reserve. Test Sale or Exchange: The Secretary of Energy is authorized to carry out test drawdowns and distribution of crude oil from the Reserve. If any such test drawdown includes the sale or exchange of crude oil, “then the aggregate quantity of crude oil withdrawn from the Reserve may not exceed 5,000,000 barrels during any such test drawdown or distribution.” [1] "The Energy Policy and Conservation Act (P.L. 94-163, 42 U.S.C. 6201)", enacted December 22, 1975.

    Beyond Climate Confusion: Why Both Energy Innovation and Deployment Matter
    I have a new essay in the May/June issue of Foreign Affairs—“The Clean Energy Revolution: Fighting Climate Change with Innovation”—which I co-authored with Teryn Norris, a former advisor at the Department of Energy (DOE). We are grateful for the positive and constructive comments we’ve received, but I do want to respond to a pair of critical posts by Joseph Romm, formerly an acting Assistant Secretary at the DOE under President Clinton. I hope we can put to rest an unhelpful debate among those passionate about confronting climate change, or, at the very least, respectfully agree to disagree. First, here’s some of the positive coverage of our essay. Bill Gates called it “One of the best arguments I’ve read for why the U.S. should invest in an energy revolution.” A visionary who plans to double his personal investment in clean energy technology ventures to $2 billion over the next five years, Mr. Gates is reinvigorating the sector, and we’re honored by his endorsement. One of the best arguments I've read for why the U.S. should invest in an energy revolution: https://t.co/58978QoWeY pic.twitter.com/xJV5Dm8hSp — Bill Gates (@BillGates) April 20, 2016   Gernot Wagner, a senior economist at the Environmental Defense Fund and author of Climate Shock, called it “clean energy revolution, walk-and-chew edition: price carbon, *and* innovate.” On the other side of the aisle, Rich Powell, Managing Director at the conservative ClearPath Foundation, called it “the best summary of our clean energy innovation challenge I’ve read.” Finally, David Roberts at Vox also wrote an article about our essay, remarking, “Here’s a sign of a more constructive debate on clean energy innovation.” I was gratified he recognized our intent to embrace intelligent policies that advance both innovation in and deployment of clean energy technologies “without forcing unnecessary either-or choices.”[1] He quoted our essay’s thesis: "Fighting climate change successfully will certainly require sensible government policies to level the economic playing field between clean and dirty energy, such as putting a price on carbon dioxide emissions. But it will also require policies that encourage investment in new clean energy technology, which even a level playing field may not generate on its own." We set out to write an inclusive essay, and we sincerely appreciate that most readers recognized that. Unfortunately, Dr. Romm chose to interpret our essay as a one-sided argument for innovation at the expense of deployment. That characterization is neither accurate nor constructive, as I’ll demonstrate. Of Red Herrings and Straw Men The first critical post runs over 4,000 words, under the headline, “We Fact-Checked A High-Profile Article On Climate And Energy. It Wasn’t Pretty.”[2] The post boils down to three central contentions: 1.We have made a factual error by asserting, “If the world is to avoid climate calamity, it needs to reduce its carbon emissions by 80 percent by the middle of this century—a target that is simply out of reach with existing technology.” 2. It is impossible to achieve deep reductions in greenhouse gas (GHG) emissions by mid-century using "mysterious nonexistent technology.” 3. Existing clean energy technologies have fallen in cost and will continue to do so as a function of their deployment, which implies that they are sufficient to achieve ambitious climate goals. It should be clear that only the first contention is amenable to straightforward fact-checking. So the title is a red herring that does not reflect the bulk of the post’s discussion, which invites complex, rather than yes/no, answers. We answered the factual question immediately after Dr. Romm published his post. Climate models suggest that global GHG emissions must fall by 75–90 percent by 2050, compared with 2010 levels, to provide the best chance of limiting climate change to 1.5 degrees Celsius. This is a warming level above which scientific uncertainty about the effects of climate change increases substantially. As a result, the Paris Agreement reflects an aspiration to meet this target. Dr. Romm did not contest this fact. We do concede, however, that we could have been clearer in explaining the context behind the 80 percent GHG reduction figure. Still, whether the required reduction is 60 percent (to limit warming to two degrees) or 80 percent by 2050, improved technology can accelerate progress toward either of the targets. And the emissions reduction challenge will not end in 2050, another reason why it is crucial to make long-term investments in innovation today. The second contention suffers from another logical fallacy: it sets up our essay’s argument for supporting innovative technologies as a straw man argument favoring “mysterious nonexistent technology.” I am genuinely surprised by this contention, especially because of its author. Dr. Romm and I are both trained physicists. And my experience in the lab, working with some of the best scientists in the world on a revolutionary solar energy technology, proved to me that the breakthroughs we need are within reach. The technologies we need to develop are neither mysterious nor nonexistent—science and technology enable us to probe materials at the nanoscale and simulate novel ideas on supercomputers. And, as Dr. Romm and I both know, the academic literature brims with sanguine reports that do just that. Concretely, in our essay we propose several clean energy technologies that the world needs to achieve deep decarbonization. We write: "New reactor designs could make nuclear meltdowns physically impossible, and nanoengineered membranes could block carbon emissions in fossil-fueled power plants. Solar coatings as cheap as wallpaper could enable buildings to generate more power than they consume. And advanced storage technologies—from energy-dense batteries to catalysts that harness sunlight to split water and create hydrogen fuel—could stabilize grids and power vehicles. The wish list goes on: new ways to tap previously inaccessible reservoirs of geothermal energy, biofuels that don’t compete with food crops, and ultra-efficient equipment to heat and cool buildings. Every one of those advances is possible, but most need a fundamental breakthrough in the lab or a first-of-its-kind demonstration project in the field." For example, there are several candidate chemistries for an energy-dense battery that could power long-range, inexpensive electric vehicles (DOE’s Quadrennial Technology Review names lithium-sulfur, magnesium-ion, zinc-air, and lithium-air), but further lab science is needed to develop these technologies. And whereas solar perovskites have excelled in lab efficiency tests, they still need real-world experience to persuade investors and customers to trust the product. None of these technologies are mysterious or non-existent, but they will require resources and time to achieve commercial entry and displace fossil fuels. Dr. Romm argues that the pace of previous energy transitions and the colossal amounts of capital required for such a transition preclude next-generation technologies from playing a major role before 2050. I disagree. That Dr. Romm can point to a particular example of a slow technology development cycle (he references “thorium-based nuclear power”) should not entail inductive license to dismiss every other technology out of hand. At the 2015 Paris summit, Energy Secretary Ernest Moniz provided a compelling vision for nuclear technology development: "If we have a viable pathway at building nuclear power in smaller bites, the whole financing structure can change and make it much more affordable…If we can demonstrate let’s say the first modular reactor in the early part of the next decade, then what we hope is it’s part of the planning process in the middle of the next decade for our utilities. Around 2030 the 60-year lifetime of existing reactors will start to kick in, and that’s a time period when utility commitments to a new round of nuclear will be especially important…If a couple of [the more than 50 privately funded companies developing advanced nuclear technologies] make it it’s a big deal." And even though there may not be a good precedent for a rapid transition in the energy sector, there are other infrastructure sectors that have been transformed rapidly by innovation. Consider fiber optic networks, which compose a massive global infrastructure system. Over the last four decades, the information capacity of these networks has increased by a factor of roughly ten million. Real scientific breakthroughs and the deployment of innovative technologies made this possible (for more on the science, see this article on Keck’s Law). Partnering Innovation with Deployment Dr. Romm’s third contention is actually one on which we share substantial common ground. We should celebrate the fall in the costs of several clean energy technologies as a function of their cumulative production (the “experience” effect). But I do disagree with Dr. Romm’s extrapolation that existing technologies will suffice to meet the climate challenge. Still, I think that their deployment plays an important role in paving the way for superior technologies to succeed them. Deployment can lead to financial and business model innovation, as we see with residential solar leases in the United States or rural microgrid ventures in India and East Africa. Similarly, governments can hone policies through the experience of deployment, like the streamlined renewable energy permitting, inspection, and interconnection regimes in Germany. Utilities learn how to manage grids that overflow with intermittent power. Investors learn how to finance large projects that deliver steady cash flows but are unfamiliar to most investors. And innovative companies look for viable deployment pathways to ensure that their investments in technology development can pay off. Today’s technologies alone won’t actually power tomorrow’s world. But they could make it possible for advanced successors to do so. There are clear limits to the potential for existing technologies to meet climate targets. For example, the International Energy Agency warns, “Carbon capture and storage (CCS) remains a vital technology to meet long-term global climate goals for emissions reduction...To reduce the cost gap and stimulate innovation, increased policy action is needed to create more market opportunities in parallel with continued research and development (R&D).” As emerging economies like India invariably build more fossil-fuel generators, cost-effective CCS technology will indeed be essential. Early CCS deployment efforts have experienced setbacks, such as construction delays and cost overruns (cf. Southern Company’s Kemper Project), but the deployment process will yield valuable insights into how to better budget, plan, and implement large CCS retrofit projects in the future. Still, the technology used in current-generation CCS projects to capture CO2, amine absorption, is inadequate for a widely deployable solution to decarbonizing the world’s fossil-fueled power plants. Instead, membrane separation and metal-organic framework capture technologies, which are showing promise in the lab, could meet the performance criteria for a scalable CCS solution.[3] Dr. Romm’s argument is more convincing with respect to solar energy, which has become increasingly competitive with conventional energy sources as a result of rapid deployment. Harvard Professor David Keith recently predicted that solar’s dramatic price declines may obviate the need for technology improvements. I think the jury is still out, but we have good reasons to expect that technology improvements will be necessary for solar power to become truly mainstream by mid-century, as GTM Research director Shayle Kann and I wrote in Nature Energy last month. Still, I will be pleasantly surprised if I am proven wrong. Indeed, just this week, a Saudi-backed consortium placed an astonishingly low bid to build a solar farm in Dubai for only 3¢/kWh, half the local price of power from natural gas. Existing technologies may surprise us, as Dr. Romm suggests, especially if this bid turns into a contract and Dubai’s prices can be replicated elsewhere in the world. (I am skeptical, though, of the latter possibility).[4] Deployment and innovation go hand in hand. Sometimes, policies that encourage deployment can discourage innovation. I contend, for example, that some solar deployment policies create ring-fenced markets in which mature technologies can lock out emerging competitors through incumbency advantages. But in most cases, public and private resources for deployment do not come at the expense of resources for innovation. And by holistically designing policies that support both emerging technologies as well as mature ones, as we argue in our essay, policymakers can most cost-effectively confront climate change. We assert that a price on carbon, in conjunction with increased support for research, development, and demonstration of innovative clean energy technologies, can best coordinate innovation with deployment. I hope this resonates with anyone committed to the cause of combating climate change. I invite Dr. Romm and others who might disagree with me to engage in civil discourse—we have a lot to learn from each other. And if we find we have irreconcilable differences, I will be more than happy to respectfully agree to disagree. [1] I also want to thank CFR’s Michael Levi and Andy Revkin at the New York Times for helping me understand the importance of an inclusive approach to climate change mitigation that embraces both innovation and deployment. [2] Dr. Romm’s second post references the disagreements with our essay previously set out in his first post. But the second one focuses on Bill Gates and makes a third logical fallacy—an inappropriate ad hominem attack: “Gates, however, appears to be someone who doesn’t really listen to the advice of experts. This affliction—common to billionaires (I’m looking at you Donald Trump)—shines through from the very beginning of this interview [with the magazine, Technology Review].” [3] I thank Mengyao Yuan at Stanford University for technical guidance on CCS research. [4] Developers building projects at Dubai’s Mohammed bin Rashid Al Maktoum solar park enjoy a lower cost of capital than any counterpart around the world. Equity has historically been cheap because the Dubai Electricity and Water Agency (DEWA) takes a majority equity stake; debt is also cheap because of sovereign guarantees, for example from the Saudi government.
