Abstract:
What are the international implications of China’s rise? What developments may be expected, and what should U.S. national defense leaders do about the likely effects of these developments? China is a rising power but even if that cannot be said to translate into a security threat to the United States directly, there is little reason to believe that Beijing will not take action to get out from under what it perceives as unfriendly U.S.-led global diplomatic, economic, and security orders. In very broad terms, U.S. defense policy makers will need to address the change from military capabilities for enforcing a liberal international order, to capabilities for both advancing and protecting friendly regional or even sub-regional orders. China’s potential power is sizable and increasing based on a large population and growing national wealth and this potential power makes its neighbors fear that it will become the regional hegemon. Since other states in the region cannot predict if or when Beijing will make a bid for hegemony, relations are beset with uncertainty. Weaker neighbors, like Vietnam and Laos in Southeast Asia, can be expected to accommodate Beijing more while trying to benefit from Chinese economic growth when and where possible.1 The U.S. security allies can be expected to cooperate more with each other while calling for more visible displays of U.S. commitment (including more military force presence).2 India will become more important to U.S. strategy as a link between Australia and Thailand, and the Middle East and Central Asia, and the Pacific and Indian Oceans.

Abstract:
The transition to a low-carbon energy system will likely shake up the geopolitical status quo that has governed global energy systems for over a century. Policymakers need to rethink the role their country could play in a new energy world. Renewables are widely perceived as an opportunity to shatter the hegemony of fossil fuel-rich states and democratize the energy landscape. Virtually all countries have access to some renewable energy resources (especially solar and wind power) and could thus substitute foreign supply with local resources. Our research shows, however, that the role countries are likely to assume in decarbonized energy systems will be based not only on their resource endowment but also on their policy choices. Renewable hydrogen is enjoying growing political and commercial momentum as a versatile and sustainable energy carrier with the potential to play a key role in the global transition to a low-carbon economy; and it is often described as the ‘missing link’ in global decarbonization—especially for energy intensive sectors where emissions are hard to abate and electrification is not the preferred solution, such as steel production, high-temperature industrial heat, shipping, aviation, and heat for buildings. But making renewable hydrogen a significant part of the world’s future energy mix will require defining new and innovative national and international policies while developing appropriate market structures aimed at spurring innovation along value chains; scaling technologies while significantly reducing costs; and deploying enabling infrastructure at scale. Success is possible, but this transformational effort will require close coordination between policy, technology, capital, and society to avoid falling into the traps and inefficiencies of the past. Renewable hydrogen can be used for both mobility and stationary applications. As a sustainable mobility energy carrier, it can power fuel-cell electric vehicles or be the base for synthetic fuels. In stationary applications, it can be used to store renewable energy, both at utility scale or off-grid, providing backup to intermittent renewable energy sources and serving as a carbon-free heating source. From a geopolitical perspective, whether future renewable hydrogen energy systems will be as concentrated as today’s oil and gas supply or decentralized like renewables is strongly related to future market structures, technology, and enabling infrastructure availability.

3. China: The Renewable Hydrogen Superpower?

Abstract:
President Xi Jinping’s pledge during the 2020 United Nations General Assembly, that China would reach peak carbon dioxide emissions by 2030 and achieve carbon neutrality before 2060, is a significant step in the fight against climate change. Since China is the world’s top contributor of greenhouse gases, there is no doubt that Beijing needs to be front and center of any effort to curb global emissions. In 2019, China accounted for almost 30 percent of global emissions, about twice as much as the second largest emitter, the United States.1 But while U.S. emissions have been on an overall decline since 2007,2 China’s have increased, raising concerns over whether Beijing can actually deliver on its targets. This reality should not distract from the fact that China is also the world’s top developer of renewables and other clean energy technologies. For example, China was the world’s largest installer of photovoltaics (PV) by 2013 and, in less than two years, also became the global leader in solar module manufacturing. At the same time, China leveraged its industrial might and economies of scale to drive down modules’ costs—which, by the end of 2018, were 90 percent lower than only ten years before. In this context, renewable hydrogen could significantly accelerate China’s transition to a low-carbon economy, increasing the likelihood of meeting its carbon neutrality goal. Renewable hydrogen offers significant advantages for China. It can help Beijing meet its climate and pollution goals—at a time when coal continues to dominate—while avoiding increased reliance on imported fuels. As a readily dispatchable means of storing energy, hydrogen can help to address intermittency and curtailment issues as renewable energy increases its share of China’s energy mix. As a sustainable mobility energy carrier, it can power fuel-cell electric vehicles or be the base for synthetic fuels. Finally, renewable hydrogen can open new avenues for developing clean technology manufactured goods for both internal and export markets. Today, most of China’s hydrogen is produced from coal via 1,000 gasifiers, accounting for 5% of the country’s total coal consumption. Hydrogen costs vary significantly as a function of production technology and prices of fossil fuels and electricity. Production from coal remains the lowest cost option: about 30 percent cheaper than hydrogen from natural gas. Therefore, reducing the carbon footprint of coal-based hydrogen will be critical in a low-carbon economy. In the medium term, coal-based hydrogen with carbon capture, utilization and storage will likely remain China’s lowest-cost clean hydrogen production pathway. Hence, the underlying question is whether Beijing will prioritize cost considerations or put its full industrial might behind the development and deployment of renewable hydrogen. In March 2019, the Chinese government took a significant step forward by announcing measures to promote the construction of hydrogen facilities for new energy vehicles. Wan Gang, who is known as China’s “father of the electric car,” called for China to “look into establishing a hydrogen society” and “move further toward fuel cells.”3 Given that Gang made a similar call two decades ago on vehicle electrification, which played a key role in China’s current battery electric vehicles market dominance, close attention is warranted.
