Abstract:
The transportation sector is the second-largest source of CO2 emissions, after electricity and heat generation, accounting for about 25 percent of global emissions.1 However, it is also one of the most challenging to decarbonize due to its distributed nature and the advantages of fossil fuels in terms of high energy densities, ease of transportation, and storage. Moreover, the degree of difficulty in decarbonizing varies significantly across the sector, making the challenge even more daunting. So far, emissions reduction strategies have focused on improving vehicle and system-wide efficiencies, mode switching, and electrification. The latter is proving relatively easy for smaller vehicles that travel shorter distances and carry lighter loads. However, sector-wide decarbonization pathways will require a transition to low-carbon fuels and the deployment of enabling infrastructure to support innovation at scale. Renewable hydrogen holds promise in sustainable mobility applications, whether by powering fuel-cell electric vehicles (FCEVs) like cars, trucks, and trains or as a feedstock for synthetic fuels for ships and airplanes. Fuel cells convert hydrogen-rich fuels into electricity through a chemical reaction. FCEVs use a fuel cell, rather than a battery, to power electric motors, and operate near-silently and produce no tailpipe emissions. Hydrogen-powered vehicles offer key advantages, including shorter refueling times, longer ranges, and a lower material footprint compared to lithium battery-powered alternatives. However, high costs of ownership and a lack of enabling infrastructure are key challenges that must be addressed through policy support, technological innovation, and financial investment. Hydrogen can complement existing efforts to electrify road and rail transportation and provide a scalable option for decarbonizing shipping and aviation. Figure 1 summarizes the mobility segments for which battery electric vehicles (BEVs), FCEVs, and vehicles running on bio- or hydrogen-based synthetic fuels are most applicable.

Abstract:
Clean hydrogen is experiencing unprecedented momentum as confidence in its ability to accelerate decarbonization efforts across multiple sectors is rising. New projects are announced almost every week. For example, an international developer, Intercontinental Energy, plans to build a plant in Oman that will produce almost 2 million tons of clean hydrogen and 10 million tons of clean ammonia.1 Dozens of other large-scale projects and several hundred smaller ones are already in the planning stage. Similarly, on the demand side, hydrogen is gaining support from customers. Prominent off-takers such as oil majors like Shell and bp, steelmakers like ThyssenKrupp, and world-leading ammonia producers like Yara are working on making a clean hydrogen economy a reality. Despite the optimism surrounding clean hydrogen, key uncertainties remain. One of hydrogen’s attractions is that it can provide carbon-free energy in multiple sectors—transport, heating, industry, and electricity generation. But this advantage also creates uncertainties. The infrastructure needed in an economy in which hydrogen is primarily used as a transport fuel is very different from one in which its primary value is as a heating fuel. Today no major hydrogen pipeline networks exist,2 and no liquified hydrogen ships are in commercial operation. There is a true chicken and egg problem. If there is no infrastructure to move hydrogen, will investments in supply and demand happen at the pace needed to meet national decarbonization targets? This challenge raises an even more pressing question: what should be the respective roles of the public and private sectors in deploying enabling infrastructure at scale?

Abstract:
A rainbow of colors currently dominates almost every conversation on the transition to a low-carbon economy: green, grey, blue, turquoise, pink, yellow[1] - an ever-increasing palette to describe the same colorless, odorless, and highly combustible molecule, hydrogen. The only difference is the chemical process used to produce it. The colors of hydrogen are crucial for the energy transition because each production pathway generates different amounts of greenhouse gas emissions. For example, while grey hydrogen, produced from fossil fuels, yields up to 20 tons of carbon dioxide per ton of hydrogen, green hydrogen, produced from renewable energy sources like solar and wind, yields no emissions. Furthermore, although these colors all refer to the same molecule, production costs differ: green hydrogen remains substantially more costly today. With aggressive development and deployment of electrolyzers and other hydrogen technologies at scale, green hydrogen could become cost-competitive with blue hydrogen, produced from natural gas with carbon capture, by 2030 in many countries.[2] Overall, the rate at which green hydrogen costs decrease will also depend on government policies and incentives, such as carbon pricing and tax credits. Therein lies a critical challenge for the successful transition to a low-carbon economy. As energy systems increasingly evolve from centralized to decentralized, from “grey” to “green,” stakeholders will need to efficiently account for and track emissions and green molecules in a transparent, secure, and standardized way, and must be able to do so along value chains from production to consumption.

34. The European Union at a Crossroads: Unlocking Renewable Hydrogen’s Potential

Abstract:
European countries are at a crossroads on their path to carbon neutrality. Today, they are at the forefront of the global clean hydrogen race but going forward they would be better served by collaborating instead of working alone. Overall, the European Union (EU) is highly competitive in clean technologies manufacturing and thus well-positioned to benefit from the emergence of global hydrogen markets. But a narrow focus on short-term cost considerations could drive member states to implement national roadmaps with little or no coordination among themselves and hence little or no chance of competing globally. As a bloc, the EU has pledged to reach carbon neutrality by 2050. Clean hydrogen is a cornerstone of this transformational effort; accordingly, in July 2020, the EU adopted its hydrogen strategy with the ambition of deploying open and competitive clean hydrogen markets for all energy sectors and segments by 2050.1 Success hinges around implementing a cohesive long-term strategy to address a fundamental ques- tion and its associated challenges: where could the EU source competitive and secure renewable hydrogen supplies? As our previous research shows, all countries have access to renewable resources (such as solar or wind), to different degrees, and could produce some renewable hydrogen locally. However, while resource-rich countries, such as Spain, could evolve into regional exporters, no EU member state has the potential to become a global export champion. At the same time, North African countries, such as Morocco, are well-situated to act as key suppliers to the EU. Furthermore, imports from resource-rich regions like North America could help to address security of supply concerns.2 Today, EU hydrogen demand stands at 7.8 million tons per year (Mt/yr), equivalent to about 10% of global demand. Germany and the Netherlands are the largest consumers, accounting for over a third of EU demand, followed by Poland, Spain, Italy, Belgium, and France, which consume about 0.5 Mt/yr each.3 According to available projections, as hydrogen use grows across all economic sectors, EU hydrogen demand could reach 76 Mt/yr by 2050. But while the EU strategy sets clear targets on electrolyzer deployment by 2030, it provides very few details on how the bloc could meet demand—and at what cost—by 2050.

Abstract:
In the last decade, many states set ambitious goals to decarbonize their energy portfolios. Seven states along the Atlantic coast are pursuing 100% clean electricity targets, while others have adopted stringent emissions reduction targets.1 Realizing these goals requires scaling wind, solar, and other renewable resource electricity generation at rates three to four times recent levels. If wind is to play a significant role in decarbonizing the electricity sector in the densely populated northeast section of the United States, a substantial proportion of the investment must occur offshore, as onshore wind speeds and available land area are limited. Some states have taken an additional step by establishing specific offshore wind targets. For example, New York's 2019 Climate Leadership and Community Protection Act contains a goal of 9,000 MW of offshore wind by 2035.2 This policy brief examines the economic and technical feasibility of substantial wind generation development along the Eastern Seaboard.

Abstract:
Central Bank Digital Currencies (CBDCs) have rapidly evolved from a sci-fi concept to a plausible alternative to cash that is being studied by central banks all over the world. According to a Belfer Center tracker, over 50 central banks have pursued or are engaging in CBDC work as of August 2020. However, while 10 central banks have already piloted or announced plans to pilot a CBDC in the near term, most are in the early stages of research and experimentation. In this brief, we outline the common motivations driving central bank work on CBDCs. We then explore CBDCs’ potential impacts on financial inclusion, a primary motivation in developing and emerging markets that has also gained significant traction in developed economies during the COVID-19 related global recession. We conclude that for CBDCs to achieve its financial inclusion goals, more technical advancement in offline adaptability and policy deliberations around issues of identity and traceability are needed.

Abstract:
Imagine a speculative technology, one that is destined to change lives and improve the world, but also one where many scientific and practical questions remain to be answered. Companies and entrepreneurs, already seeing the potential, have begun spinning up new efforts and launching startups to realize products and services. You know that investors are likely underestimating both the difficulty posed by the technology and the long-term impact. The science and engineering remain far from that necessary to achieve those goals, much less understand the unintended consequences. You are now tasked with enabling the economic growth implied by these opportunities while ensuring both scientific progress and minimizing unintended negative outcomes. What do you do? Faced with this challenge in the still esoteric field of quantum information science, leaders in the Government and I worked with stakeholders from across the United States and around the world to build a foundational approach for this new technology. Rather than using a roadmap with product or milestone driven development, we instead focused on building a community around the emerging technologies and scientific challenges necessary to build quantum computers. These are devices that operate at the very limits set by nature in what and how they compute and are fantastically hard to create – so much so that their basic operation and architecture are areas of active research. And their impact is fantastically broad, thus the need to both temper expectations and enable cooperation. In executing a program to enable this new sector, we developed a specific approach for solving the challenge of blending profit motive and public good that leverages the mechanism of consortia. We are at a moment in time where cooperation between public-purpose stakeholders and profit-motive stakeholders can be an effective means of integrating public purpose into technology as it emerges. This brief covers the basic concept of a public-purpose consortium (PPC), examination of what combination of factors lead to their use for emerging technologies, and considers the key principles for organizing PPCs and enabling their success: Build Community, Enable Cooperation, Ensure Value, Institute Governance, and Keep It Lightweight.

Abstract:
This election has already faced threats from cyber adversaries seeking to influence its outcome. The joint CISA-FBI alert confirming Russian state-sponsored activity targeting government networks on October 22 builds on other advisories around potential cyberattacks on election systems ahead of the election, including advisories of DDOS attacks against election infrastructure. Making unplanned or last-minute changes ahead of election day can introduce serious risks, especially given the short window to test changes. Here are some considerations as you work to address and prepare to counter potential cyber threats.
