Summary of "Is China's Hydrogen Economy Coming?"

Core Content

This report explores the potential for China to develop a hydrogen economy as part of its transition to a low-carbon future. It analyzes the role of renewable hydrogen in China's energy strategy, considering government support, production pathways, market potential, and the geopolitical implications of hydrogen as a clean energy carrier. The report highlights how hydrogen can serve as a critical component in decarbonizing sectors that are difficult to electrify, such as heavy industry, aviation, shipping, and long-distance transportation.

Main Points

1. Government Support

• The Chinese government has shown strong support for hydrogen development, similar to its support for battery electric vehicles (BEVs).
• In 2019, the government announced ambitious targets for fuel cell electric vehicles (FCEVs) and hydrogen infrastructure, aiming to have 5,000 FCEVs on the road by 2020, 50,000 by 2025, and 1 million by 2030.
• It plans to build 100 hydrogen fueling stations by 2020, 300 by 2025, and 1,000 by 2030.
• Despite reduced subsidies for new energy vehicles (NEVs), the government continues to invest in hydrogen technology and infrastructure.

2. Production Pathways, Market Potential, and Costs

• Hydrogen Production: Hydrogen is produced through thermo-chemical, biochemical, and water electrolysis methods. Currently, most hydrogen in China is produced from coal, accounting for about 5% of total coal consumption.
• Renewable Hydrogen: To achieve its environmental benefits, hydrogen must be produced from zero-carbon sources like renewables or nuclear energy. China's renewable hydrogen production is still in its early stages but has significant growth potential.
• Market Potential: Renewable hydrogen is expected to play a key role in the future energy mix, especially in sectors where electrification is challenging.
• Costs: Coal-based hydrogen is currently the cheapest option in China, about 30% cheaper than natural gas-based hydrogen. However, the carbon footprint of coal-based hydrogen must be reduced for it to be viable in a low-carbon economy. In the medium term, coal-based hydrogen with Carbon Capture, Utilization, and Storage (CCUS) may remain the lowest-cost clean hydrogen pathway.

3. Technology Focus: Hydrogen Fuel Cells

• Fuel Cells: These devices convert hydrogen into electricity through a chemical reaction, producing only water and heat as byproducts. They do not require periodic recharging and operate silently.
• FCEVs: Fuel cell electric vehicles (FCEVs) offer a driving range of 400-600 km, comparable to conventional vehicles. Refueling takes less than five minutes, making them more convenient than BEVs, which require longer charging times.
• Applications: Hydrogen fuel cells can be used in both mobility and stationary applications, including backup power, distributed generation, and carbon-free heating.

4. Geopolitical and Market Map

• Renewable Energy Resources (RES) Endowment: China has a high RES endowment, with a potential of 98.2 PWh, significantly exceeding its domestic primary energy consumption of 34.8 PWh. This allows for the export of up to 63.4 PWh of excess renewable energy.
• Freshwater Resources: Freshwater availability is a key factor in hydrogen production. China has relatively abundant freshwater resources, which supports its potential for renewable hydrogen production.
• Infrastructure Potential: Despite its RES potential, China's hydrogen infrastructure is underdeveloped, especially in the Southwestern region where RES are abundant but far from economic centers. This requires significant investment to connect supply with demand.

5. Role of Renewable Hydrogen in China's Low-Carbon Transition

• Renewable hydrogen can help China reduce its reliance on coal and imported fuels while meeting its climate and pollution goals.
• It can also serve as a storage solution for renewable energy, addressing intermittency and curtailment issues.
• The development of a hydrogen economy could enhance China's technological leadership and provide new export opportunities, especially in Southeast Asia.

6. Policy and Commercial Options

• Policy Support: Governments need to support the deployment of hydrogen infrastructure and R&D efforts to reduce costs.
• Commercial Strategy: Companies are investing in FCEV production and hydrogen technology. For example, China National Heavy-Duty Truck Group plans to invest $7.6 billion in FCEVs, while Mingtian (Tomorrow's) Hydrogen aims to produce 100,000 fuel-cell stacks by 2022.
• Nuclear Hydrogen: Nuclear power could play a key role in producing carbon-free hydrogen, especially given China's ambitious nuclear expansion. Nuclear hydrogen could provide additional revenue streams for nuclear plants and support the transition to a low-carbon economy.

Key Information

• Current Status: China is the world's largest hydrogen producer, with 22 million tons (Mt) produced annually, mostly from coal.
• Future Outlook: Renewable hydrogen could become a significant part of China's energy mix, especially in the Southwestern region with high RES and freshwater availability.
• Challenges: High costs of fuel cells, lack of infrastructure, and competition with BEVs are major obstacles to the widespread adoption of hydrogen vehicles.
• Geopolitical Implications: Renewable hydrogen could become a key component of the Belt and Road Initiative (BRI), enhancing China's global influence in the fight against climate change.
• Conclusion: If China can leverage its manufacturing and policy capabilities, it could become a global leader in the hydrogen economy, with far-reaching implications for energy, environment, and geopolitics.
