To accelerate the global transition to a low-carbon economy, all energy systems must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, clean hydrogen – defined as hydrogen produced from water electrolysis with zero-carbon electricity – has captured increasing political and business momentum as a versatile and sustainable energy carrier in the future carbon-free energy puzzle.

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. 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.

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.

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.

This paper focuses on China and the potential role of renewable hydrogen in accelerating its transition to a low-carbon economy. Our research goal is to provide policymakers and other stakeholders the means to make informed decisions on technology innovation, policy instruments, and long-term investments in enabling infrastructure.

The peer-reviewed update of ENRP's ongoing research on renewable hydrogen is featured in the June volume of Geopolitics, History, and International Relations, an academic journal of which Dr. Nicola de Blasio is now also an editor.

To accelerate the global transition to a low-carbon economy, all energy systems and sectors must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, renewable hydrogen is drawing increased attention today as a versatile and sustainable energy carrier with the potential to play an important piece in the carbon-free energy puzzle. Countries around the world are piloting new projects and policies, yet adopting hydrogen at scale will require innovating along the value chains; scaling technologies while significantly reducing costs; deploying enabling infrastructure; and defining appropriate national and international policies and market structures.

What are the general principles of how renewable hydrogen may reshape the structure of global energy markets? What are the likely geopolitical consequences such changes would cause? A deeper understanding of these nascent dynamics will allow policy makers and corporate investors to better navigate the challenges and maximize the opportunities that decarbonization will bring, without falling into the inefficient behaviors of the past.
