Abstract:
In the United States, commercial and residential buildings produce roughly 12 percent of greenhouse gas emissions. Most of these emissions come from burning fossil fuels for space heating. These emissions must be significantly reduced or eliminated for the US to achieve deep decarbonization goals, including net zero emissions by midcentury. Air source heat pumps (ASHPs) are powered by electricity, using well-established technology to move heat from outdoor air to indoor air. When powered by zero-carbon electricity, ASHPs provide space heating with almost no greenhouse gas emissions. ASHPs are especially effective for space heating in mild climates. In 2015, roughly 10 percent of US households (mostly in the Southeast) used air source heat pumps as their primary heating source.[1] ASHPs account for roughly one-third of residential space heating in Japan. The world’s largest ASHP market is in China, where sales are growing rapidly. Prominent studies on decarbonization of the US energy system focus on deployment of air source heat pumps as the primary strategy for reducing emissions from space heating. Some studies show near-universal electrification of space heating, suggesting that ASHPs (with some backup from electric resistance heaters) can be almost a silver bullet solution for decarbonizing space heating. These studies start with the assumption that fossil fuel furnaces and boilers will be gradually phased out. Other studies assume that electric heating technologies such as ASHPs will continue to compete against fossil fuel burning furnaces and boilers in the decades ahead. These studies conclude that furnaces and boilers will retain a significant share in space heating markets, even with technological progress and strong policy support for ASHPs, but often fail to explain why. Do high costs or inferior performance limit market penetration in these studies? Or do other barriers limit ASHP deployment? The answer has important implications for policy makers shaping decarbonization strategies. To help answer these questions, we built a simple model of ASHP adoption that estimates the lifetime costs of space heating and cooling configurations in three US cities with markedly different climates and energy costs: Atlanta, Georgia; San Diego, California; and Fargo, North Dakota. The model analyzes the choices facing hypothetical consumers installing new heating and cooling equipment in residential buildings. The consumers have the option to purchase an ASHP for heating and cooling (with backup if needed) or a natural gas furnace and air conditioner. Based on the model results and related research, we conclude: Air source heat pumps are cost competitive today in places where electricity is cheap and the climate is mild. With climate policies consistent with rapid decarbonization and reasonably foreseeable technological progress, air source heat pumps are the low-cost option for typical residential buildings across much of the US by the mid-2030s. Even in the very cold climate of Fargo, North Dakota, the combination of a price on carbon emissions and steady innovation in ASHPs causes ASHPs (with an electric resistance heater as a backup) to be cost competitive with new natural gas furnaces and air conditioners by the 2030s. If the United States commits to the rapid decarbonization of space heating by midcentury, the costs and performance of ASHPs are unlikely to be major barriers to deployment. However, other important barriers may persist, including contractors’ and homeowners’ greater familiarity with incumbent fossil fuel technologies and the slow turnover of the building stock. As a result of these additional barriers, emissions pricing and technological progress alone may not lead to deployment of air source heat pumps in the United States sufficient to achieve deep decarbonization by midcentury. That would likely require additional policy instruments such as technology standards, emissions caps, or mandates. Other technologies can also contribute to decarbonizing space heating, including renewable natural gas, hydrogen produced with carbon capture and storage (CCS) or electrolysis, and centralized or district heating. Each of these options comes with challenges that will require policy support to overcome. This study does not point to a proper balance between ASHPs and other space heating decarbonization technologies. More research is needed to compare different approaches and strategies. In the meantime, our analysis suggests little if any downside to pursuing ambitious policies to promote deployment of ASHPs, prioritizing regions where heat pumps are currently most cost effective. A large-scale increase in ASHP deployments is likely to be an important part of any space heating decarbonization scenario.

Abstract:
Sanctions are a key tool of foreign policy but have taken on greater salience over the last 20 years as governments have reached for leverage in negotiations but foregone the use of force. During this period, the alignment of the design and implementation of sanctions by the European Union and the United States has, on the whole, been an article of faith as the transatlantic allies have pursued mutual foreign policy objectives. Yet despite the consistency of objectives, the bureaucratic structures, technical mechanisms, and processes by which the European Union and the United States design and implement sanctions differ significantly. These differences—always present—have been amplified by the current stresses in transatlantic relations and may be further exacerbated when the United Kingdom leaves the European Union in March 2019. The reasons behind these differences are myriad and touch upon both structural matters (such as the construction of the European Union and the manner in which its member states can enact policy) and more philosophical matters, as the focus on due process and human rights in EU sanctions policy demonstrates. But given the importance of transatlantic ties and cooperation in managing the sorts of problems that sanctions are usually developed to address, it is important for both the United States and the European Union to work through these differences. Toward that goal, this paper provides a European perspective on US sanctions activity, where there are differences in approach, in particular EU attitudes toward secondary sanctions put in place by the United States, and it explains the complications that may result from the United Kingdom’s withdrawal from the European Union. The paper concludes with recommendations for how the European Union can address the challenges it faces in achieving an effective sanctions policy. In short, it recommends the following: The European Union should work through its structural issues to create a more decisive and effective EU sanctions policy. The implementation and enforcement of sanctions at the member state level must be improved, and a formal EU-level sanctions body is needed to independently monitor compliance with sanctions across the European Union. A clear mechanism for ensuring the coordination and effectiveness of EU-UK post-Brexit sanctions policy must be established. The global centrality of both the European Union’s economy and the United Kingdom’s financial sector combine to present a powerful sanctions force and must thus be closely coordinated to ensure maximum effectiveness. The European Union should directly address the matter of human rights exemptions by incorporating it as a key consideration of the EU-level sanctions body identified in the first recommendation. The European Union should establish a clear channel for human rights exemptions throughout the lifetime of sanctions regimes. The European Union should consider its options to address the ability of non-EU actors to abuse EU-originating supply chains and financial services, which represents a considerable sanctions implementation vulnerability. Finally, though US-EU misalignment on sanctions is growing, policy makers must stay seized of the necessity to maintain and improve communications and coordination to prevent current schisms from having serious long-term effects on international security.

13. The Impact of US LNG on Russian Natural Gas Export Policy

Abstract:
The United States and Russia have long been the world’s largest natural gas producers, but they traditionally have not faced off in direct competition in that market. The United States was expected to become a net importer of natural gas, while Russia’s state-owned Gazprom took a prominent position in the European market. The boom in US shale-gas production changed that. While the United States had been trading gas regionally by pipeline for decades, the shale boom allowed for the export of US liquefied natural gas, putting the two gas giants in competition. Even before the first molecule of US LNG shipped, rising US production had diverted LNG destined for the United States into the European Union. Facing increased competition pushed Russia toward a more market-oriented strategy, with Gazprom adjusting its long-term oil-linked contracts that had previously been the backbone of Russian sales to European customers to use more hybrid formulae. This was just the beginning. After a slow start, the competition brought on by US gas is to a large extent shaping the Russian natural gas strategy in Europe and beyond. For Europe, rising gas competition from new suppliers has both economic and energy security implications. Globally, it is also raising questions about how Gazprom will compete in Asia, where demand is growing and gas suppliers are looking to place future production, as well as in other markets. Understanding how Gazprom will react to US gas is thus a critical economic and geopolitical question for LNG importers and exporters worldwide. In this paper the authors examine how Gazprom will maneuver in global markets under specific circumstances. It opens with a discussion of how the US and Russian gas sectors developed and interacted in the period before shale gas. The paper then examines how Gazprom’s gas trade has been impacted by new US production and what changes may be coming as US exports continue to increase. It finds that the advent of US LNG has already reduced Russian gas revenue, undermined its oil-linked pricing model, forced contract renegotiations and accelerated domestic gas market liberalization and LNG development. The authors argue that Russia is in a good position to defend its market share in Europe and looks at some of the strategies that could be pursued under various market scenarios, including the following: High Asian demand and low oil prices: If oil-linked gas prices were pushed below spot prices, Gazprom would not need to further adjust its pricing policy (as was the case in 2015–2017). In certain situations Gazprom might even limit supplies to drive prices up and increase its rent, becoming the price maker. Such a strategy would be utilized cautiously to avoid demand destruction and prompting new FIDs for new (US) liquefaction capacity. High Asian demand and high oil prices: In this scenario Gazprom’s position would be well served in the short to medium term by strong revenues. In the longer term, however, high prices will attract more competitors to the markets (and prompt new FIDs), so it is important for Gazprom to keep its own prices competitive and to keep the margin of the aggregators, which are supplying the European market, below their margin in Asia. There are already almost no “pure” oil-linked contracts left, and Gazprom in Europe mainly has hybrid pricing, but this scenario will require a more fundamental shift in the pricing, with the share of spot-indexed prices becoming dominant. Low Asian demand and low oil prices: Gazprom may be forced to keep prices for its long-term contracts below short-run marginal costs of US LNG. Gazprom might voluntarily move to completely spot-indexed prices, simultaneously trying not only to find new markets for its gas (both in Asia and in Europe) but also to stimulate new demand. The company would need more flexible and creative marketing, and it would seek to improve the efficiency of its operations, both internationally and domestically. Should Gazprom start to see its market share decline, Moscow could decide to liberalize the pipeline export monopoly, a decision that would make Novatek and Rosneft more powerful players. Low Asian demand and high oil prices: Russia would feel competitive pressure not only from the United States but also from all existing low-cost LNG suppliers like Qatar, which may have to switch to Europe and keep gas prices at a low level. Gazprom would have to engage in this price competition as well, flooding the market using spare capacities and driving the prices down to the level of its short-run marginal costs, which will disincentive US LNG aggregators to offtake their LNG. Gazprom has considerable underutilized upstream capacities and huge spare transportation capacities, allowing it to drive down European prices below the level acceptable for US LNG suppliers. This scenario hurts everyone on the supply side, and it is warranted to ask how long it could be upheld. The study finds that even in scenarios where Gazprom sees gas revenues driven down to 2009 or 2016 levels, this should not prove catastrophic for Russia. For Moscow, facing more competition in Europe is a new situation that Gazprom and decisions makers in the Kremlin will have to deal with. Under normal circumstances, competition between various sources of supply can result in net benefits for the end consumer. In addition, this paper demonstrates that the changes in the global gas market have forced Gazprom to adjust its business practices. However, the increased politization of natural gas in the United States carries a risk of inflamed tensions between Moscow and Washington.
