Abstract:
China’s Global Energy Interconnection (GEI) initiative presents a transformational vision for meeting the world’s growing power demand with a globally interconnected electricity grid. The concept involves ultra-high-voltage transmission lines strung across vast distances and smart grid technology tapping large-scale renewable power sources. Chinese President Xi Jinping first touted GEI’s goal to “facilitate efforts to meet the global power demand with clean and green alternatives” at the UN General Assembly in 2015. The ambition of the GEI vision is enormous, especially since there is very little cross-border trade in electricity around the world today. Regional electricity integration initiatives championed by development banks and multilateral organizations have largely struggled against the formidable political, economic and technical complications that accompany interstate electricity trade. China has seen these challenges firsthand in its participation in the Asian Development Bank’s Greater Mekong Subregion electricity trade endeavor, which has progressed fitfully since the 1990s amid regional infrastructure gaps and uneven political support from member states. This report, prepared as part of the Belt and Road Initiative series published by Columbia University’s Center on Global Energy Policy, uses a case study of power trade in the Greater Mekong Subregion to assess the prospects for GEI in catalyzing energy integration around the world. It discusses why Greater Mekong Subregion integration has been slow, how GEI might help accelerate interconnection in the area, and what lessons the region offers for understanding the overall outlook for GEI. Based on this study, the author finds the following: Establishing a GEI-style global energy grid backbone by 2070 would require overcoming an extraordinary set of political challenges. The global grid outlined by GEI for the coming decades serves more as a demonstration of technical potential than a strict blueprint to be implemented. The limited scale attained thus far by the Greater Mekong Subregion project for grid integration and cross-border electricity trading demonstrates the headwinds such multinational efforts can face. Weak internal power sector development in recent decades has left some member states without the generation surpluses and robust power grids necessary to support meaningful levels of trade. In addition, power trade requires a strong degree of interstate political trust, motivated engagement by national utilities, and support from civil society players for the specific generation and transmission projects involved. Integration backers have historically struggled to build consensus across this diverse array of stakeholders. While enormous generation and transmission infrastructure projects are core components of the GEI vision and dovetail with the interests of China’s domestic proponents, considerable debate persists about their merits for fostering the renewables transition. Ultra-high-voltage transmission, a specialty of Chinese utilities, is a particular flashpoint. State interest in cross-border trade has been increasing across many regions in recent years, and more gradual gains in power trade around the world that can aid the renewable transition and bolster regional solidarity are possible. China can contribute greatly to this process: as an investor and contractor in grid projects abroad, as a member state of integration initiatives in Asia, and as an advocate of grid integration in international fora. GEI’s ultimate impact will depend in part on how advocates within China reconcile tensions between strengthening cross-border power trade and promoting domestic priorities, such as advancing the country’s own industrial policy objectives.

Abstract:
This paper examines the extent to which addressing climate-related risks and supporting sustainable finance fit into the current set of central bank mandates and objectives. To this end, we conduct a detailed analysis of central bank mandates and objectives, using the IMF’s Central Bank Legislation Database, and compare these to current arrangements and sustainability-related policies central banks have adopted in practice. To scrutinise the alignment of mandates with climate-related policies, we differentiate between the impact of environmental factors on the conventional core objectives of central banking and a potential supportive role of central banks with regard to green finance and sustainability. Of the 135 central banks in our sample, only 12% have explicit sustainability mandates, while another 40% are mandated to support the government’s policy priorities, which in most cases include sustainability goals. However, given that climate risks can directly affect central banks’ traditional core responsibilities, most notably monetary and financial stability, even central banks without explicit or implicit sustainability objectives ought to incorporate climate-related physical and transition risks into their core policy implementation frameworks in order to efficiently and successfully safeguard macro-financial stability.

Abstract:
Policy makers, academics, and others have devoted significant effort over the past three decades to considering how best to incentivize households and private companies to reduce their greenhouse gas (GHG) emissions. There has been much less discussion about how best to incentivize state-owned enterprises (SOEs) -- companies that are either wholly or majority owned by a government -- to cut emissions. Yet when it comes to energy sector GHGs, these state companies are among the world’s leading emitters. They are major emitters at both the country and global levels, notably from electricity generation. In the aggregate, they emit over 6.2 gigatonnes of carbon dioxide equivalent per year in energy sector GHGs, which is more than every country except China. Public sector companies are also major providers of low-carbon alternatives, such as renewables and nuclear power, and importantly, they often operate under incentives that are quite different from those facing their private sector counterparts. Given the emissions profile of SOEs, the nature of their corporate mandates, and their ownership structure, Columbia University’s Center on Global Energy Policy undertook research to examine how best to engage these companies in efforts to lower greenhouse gas emissions as part of its ongoing work on climate change. The paper explores the role of these public sector companies in climate change, examines the effectiveness of market-oriented solutions such as carbon taxes in changing SOE behavior, and evaluates some other potential strategies for reducing their emissions. In short, the paper finds the following: The state-ownership structure of SOEs allows governments to exercise shareholder power to press for the implementation of their climate policy preferences. Providing public sector financing and making associated infrastructure improvements are other ways that a government can encourage its SOEs to invest in low-carbon alternatives. In contrast, many SOEs operate with nonfinancial mandates, market protections, and other conditions that limit their responsiveness to carbon pricing mechanisms that are effective in changing private sector behavior. There are other ways to alter public sector companies so that they embrace a greener pathway without being directed, especially if a firm’s management determines the pathway will serve its corporate interests. This can be especially important for state-owned companies that have the political weight to resist government climate policy pressures. In emerging economies with large SOE emissions and with governments willingly direct their SOEs, using these companies to reduce emissions is a policy tactic that can present implementation and other advantages because it requires the government to target a limited number of companies that the state already owns and controls. How much a government prioritizes climate change relative to other goals is the most critical factor that will determine the extent to which its SOEs prioritize low-carbon investments. Successfully merging climate goals into growth objectives, at both the broader economic and the SOE-company levels, increases the likelihood that a state company will engage in the low-carbon transition in a sustained manner.

24. Low-Carbon Heat Solutions for Heavy Industry: Sources, Options, and Costs Today

Author:

Center on Global Energy Policy (CGEP), Columbia University
Abstract:
Recent studies indicate there is an urgent need to dramatically reduce the greenhouse gas emissions from heavy industrial applications (including cement, steel, petrochemicals, glass and ceramics, and refining). Heavy industry produces roughly 22 percent of global CO₂ emissions. Of these, roughly 40 percent (about 10 percent of total emissions) is the direct consequence of combustion to produce high-quality heat, almost entirely from the combustion of fossil fuels. This is chiefly because these fuels are relatively cheap, are widely available in large volumes, and produce high-temperature heat in great amounts. Many industrial processes require very large amounts of thermal energy at very high temperatures (more than 300°C and often more than 800°C). For example, conventional steel blast furnaces operate at about 1,100°C, and conventional cement kilns operate at about 1,400°C. In addition, many commercial industrial facilities require continuous operation or operation on demand. The nature of industrial markets creates challenges to the decarbonization of industrial heat. In some cases (e.g., steel, petrochemicals), global commodity markets govern product trade and price. Individual national action on the decarbonization of heavy industry can lead to trade disadvantage, which can be made acute for foundational domestic industries (in some cases, with national security implications). This can also lead to offshoring of production and assets, leading to carbon “leakage” as well as local job and revenue loss (with political consequences). In many cases, lack of options could lead to dramatic price increases for essential products (e.g., cement for concrete, an essential building material). Risk of carbon leakage, price escalation, and trade complexity limits the range of policy applications available to address this decarbonization need. To explore the topic of industrial heat decarbonization, the authors undertook an initial review of all options to supply high temperature, high flux, and high volume heat for a subset of major industrial applications: cement manufacturing, primary iron and steel production, methanol and ammonia synthesis, and glassmaking. From the initial comprehensive set of potential heat supply options, the authors selected a subset of high relevance and common consideration: Biomass and biofuel combustion Hydrogen combustion (including hydrogen produced from natural gas with 89 percent carbon capture (blue hydrogen) and hydrogen produced from electrolysis of water using renewable power (green hydrogen) Electrical heating (including electrical resistance heating and radiative heating (e.g., microwaves) Nuclear heat production (including conventional and advanced systems) The application of post-combustion carbon capture, use, and storage (CCUS) to industrial heat supply and to the entire facility, as a basis for comparison The authors focus on substitutions and retrofits to existing facilities and on four primary concerns: cost, availability, viability of retrofit/substitution, and life-cycle footprint. In short, the paper finds: All approaches have substantial limitations or challenges to commercial deployment. Some processes (e.g., steelmaking) will likely have difficulty accepting options for substitution. All options would substantially increase the production cost and wholesale price of industrial products. For many options (e.g., biomass or electrification), the life-cycle carbon footprint or efficiency of heat deposition are highly uncertain and cannot be resolved simply. This complicates crafting sound policy and assessing technical options and viability. Most substitute supply options for low-carbon heat appear more technically challenging and expensive than retrofits for CCUS. Even given the uncertainties around costs and documented complexities in applying CO₂ capture to industrial systems, it may prove simpler and cheaper to capture and store CO₂. CCUS would have the added benefit of capturing emissions from by-product industrial chemistry, which can represent 20–50 percent of facility emissions and would not be captured through heat substitution alone. Critically, CCUS is actionable today, providing additional GHG mitigation to industrial heat and process emissions as other options mature and become economically viable. Hydrogen combustion provided the readiest source of heat of all the options assessed, was the simplest to apply (including retrofit), and was the most tractable life-cycle basis. Today, hydrogen produced from reforming natural gas and decarbonized with CCUS (blue hydrogen) has the best cost profile for most applications and the most mature supply chain, and it would commonly add 10–50 percent to wholesale production costs. It also could provide a pathway to increase substitution with hydrogen produced by electrolysis of water from carbon-free electricity (green hydrogen), which today would increase costs 200–800 percent but would drop as low-carbon power supplies grow and electrolyzer costs drop. Hydrogen-based industrial heat provides an actionable pathway to start industrial decarbonization at once, particularly in the petrochemical, refining, and glass sectors, while over time reducing cost and contribution of fossil sources. However, substitution of hydrogen will prove more difficult or infeasible for steel and cement, which might require more comprehensive redesign and investment. Most of the other options appear to add substantially to final production costs—commonly twice that of blue hydrogen substitution or CCUS—and are more difficult to implement. However, all options show the potential for substantial cost reductions. An innovation agenda remains a central important undertaking and likely would yield near-term benefits in cost reduction, ease of implementation, and a lower life-cycle carbon footprint. Prior lack of focus on industrial heat supplies as a topic leave open many possibilities for improvement, and dedicated research, development, and demonstration (RD&D) programs could make substantial near-term progress. To avoid commercial and technical failure, government innovation programs should work closely with industry leaders at all levels of investigation. New policies specific to heavy industry heat and decarbonization are required to stimulate market adoption. Policies must address concerns about leakage and global commodity trade effects as well as the environmental consequences. These policies could include sets of incentives (e.g., government procurement mandates, tax credits, feed-in tariffs) large enough to overcome the trade and cost concerns. Alternatively, policies like border adjustment tariffs would help protect against leakage or trade impacts. Because all options suffer from multiple challenges or deficiencies, innovation policy (including programs that both create additional options and improve existing options) is essential to deliver rapid progress in industrial heat decarbonization and requires new programs and funding. As a complement to innovation policy and governance, more work is needed to gather and share fundamental technical and economic data around industrial heat sources, efficiency, use, and footprint.

25. Electric Vehicle Penetration and Its Impact On Global Oil Demand: A Survey of 2019 Forecast Trends

Author:
Marianne Kah

Content Type:
Working Paper
Institution:
Center on Global Energy Policy (CGEP), Columbia University
Abstract:
Columbia University’s Center for Global Energy Policy is undertaking a multiyear study on the prospects for and timing of peak oil demand. An essential piece of the puzzle is understanding what happens to global oil demand in the passenger vehicle sector, since it is the sector with the largest oil demand use today. Policy makers in a growing number of countries are supporting passenger vehicle electrification or a phaseout of fossil fuel passenger vehicles to reduce greenhouse gas emissions and improve urban air quality. To understand the trajectory of oil demand in this sector, it is important to comprehend the magnitude and timing of electric vehicle (EV) penetration. The pace of demand growth matters. If the world doesn’t move off oil at a rapid rate, it is important that policy makers recognize the need for investment in new oil supplies to prevent supply shortages and accompanying oil price spikes. Numerous studies analyzing the impact of EVs on oil demand have been published. It is difficult to compare these studies because they do not define the passenger vehicle sector the same way or provide underlying assumptions on a comparable basis. Last year, the author conducted a survey of all available global electric passenger vehicle penetration forecasts to compare underlying assumptions and the impact on oil demand. The author conducted a similar survey in 2019 to understand how views on EV penetration are changing. This report describes the results from the 2019 survey and indicates how views have changed since last year. Rationale for Studying the Passenger Vehicle Sector As shown in figure 1, the passenger vehicle sector is the largest sector of oil use, representing about one-quarter of the oil demand barrel. The passenger vehicle sector is a target for policy makers because full penetration of EVs could ultimately take nearly 25 million barrels per day of oil use out of the market. However, it is important to understand the other 75 percent of the oil demand barrel before assessing the prospects of peak oil demand. It should be noted that the passenger vehicle sector gets a disproportionate amount of attention from policy makers and the media because of the current focus on electrification and the greater ease of electrifying passenger cars versus other modes of transportation. For example, it is easier to electrify a passenger car than a heavy-duty truck, where the large and costly batteries required will reduce cargo carrying capacity due to weight limits on roads. It is also more challenging to electrify airplanes than passenger cars.

26. Governance of Marine Geoengineering

Centre for International Governance Innovation (CIGI)
Abstract:
After more than two decades of UN negotiations, global greenhouse gas emissions continue to rise, with current projections indicating the planet is on a pathway to a temperature increase of approximately 3.2°C by 2100, well beyond what is considered a safe level. This has spurred scientific and policy interest in the possible role of solar radiation management and carbon dioxide removal geoengineering activities to help avert passing critical climatic thresholds, or to help societies recover if global temperatures overshoot expectations of safe levels. Marine geoengineering proposals show significant diversity in terms of their purpose, scale of application, likely effectiveness, requisite levels of international cooperation and intensity of environmental risks. This diversity of marine geoengineering activities will likely place significant new demands upon the international law system to govern potential risks and opportunities. International ocean law governance is comprised of a patchwork of global framework agreements, sectoral agreements and customary international law rules that have developed over time in response to disparate issues. These include maritime access, fisheries management, shipping pollution, ocean dumping and marine scientific research. This patchwork of oceans governance contains several bodies of rules that might apply in governing marine geoengineering activities. However, these bodies of rules were negotiated for different purposes, and not specifically for the governance of marine geoengineering. The extent to which this patchwork of rules might contribute to marine geoengineering governance will vary, depending on the purpose of an activity, where it is conducted, which state is responsible for it and the types of impacts it is likely to have. The 2013 amendment to the London Protocol on ocean dumping provides the most developed and specific framework for marine geoengineering governance to date. But the capacity of this amendment to bolster the capacity of international law to govern marine geoengineering activities is limited by some significant shortcomings. Negotiations are under way to establish a new global treaty on conservation of marine biodiversity in areas beyond national jurisdiction, including new rules for area-based management, environmental impact assessments and capacity building/technology transfer. A new agreement has the potential to fill key gaps in the existing patchwork of international law for marine geoengineering activities in high-seas areas. However, it is also important that this new treaty be structured in a way that is not overly restrictive, which might hinder responsible research and development of marine geoengineering in high-seas areas.

Abstract:
European Commission president-designate Ursula von der Leyen has made climate change a top priority, promising to propose a European Green Deal that would make Europe climate neutral by 2050. Th e European Green Deal should be conceived as a reallocation mechanism, fostering investment shifts and labour substitution in key economic sectors, while supporting the most vulnerable segments of society throughout the decarbonisation process. Th e deal’s four pillars would be carbon pricing, sustainable investment, industrial policy and a just transition.

29. Neither Crowing in nor Out: Public Direct Investment Mobilising Private Investment Into Renewable Electricity Projects

Abstract:
Rapid structural change towards a low-carbon energy supply requires significant additional investments into innovative but high-risk low-carbon technologies. Mobilising greater private investments requires applying the right policy instruments, but while fiscal measures and regulation have been well researched, systematic quantitative evidence about the effect of public direct investment is lacking. Absent empirical evidence, contradictory theoretical arguments claim that such public (co- )investments either ‘crowd out’ or ‘crowd in’ private investors. In this paper we show that the macroeconomic concept of crowding out/in is inapplicable to sectoral studies such as of renewable electricity. Instead, both neoclassical microeconomics and evolutionary economics suggest public direct investment to have a positive effect due to either externalities or market creation effects. We also provide the first quantitative estimate of the effect of public direct investment on private investment into renewable electricity technologies for 17 countries in the period 2004-2014. Using FGLS and static and dynamic GMM estimators, we find that public investments not only have a positive but also consistently the largest effect on private investment flows relative to feed-in tariffs, taxes and renewable portfolio standards in general, and for wind and solar technologies separately. Implications for policy aimed at accelerating the low- carbon transition are discussed.

Abstract:
Participants from academia and various levels of government gathered in Ottawa to discuss the often underappreciated interplay between the international climate agenda and the global trade system. The trade system has traditionally supported open flows of goods and services by disciplining tariffs, as well as trade-distorting subsidies and regulations. But there is an emerging tension between this approach and the desire of governments to address climate change through potentially trade-distorting domestic regulations and green subsidies. The challenge for policy makers is how to maintain relatively free, undistorted trade, while still giving countries sufficient policy space to implement effective measures to combat climate change.
