Hydrogen Derivatives Enable Cost-Effective Carbon Neutrality in China.

Incorporating hydrogen and derivatives into China’s full energy-economy transition cuts overall decarbonization cost by $10.7 trillion versus renewable and electrification pathways, reaching negative abatement costs of −$6.15/ton.

• Why it matters: China’s large-emissions challenge includes both integrating variable renewables and decarbonizing hard-to-abate sectors, while hydrogen deployment is constrained by real-world costs and infrastructure barriers.
• What they did: The study models high-resolution renewable deployment and hourly power-system operations across 29 provincial regions, routing over 46,000 hydrogen-derivative transfers and applying process-level fuel adoption strategies across all end-use sectors.
• The result: Hydrogen-derivative pathways eliminate external oil import expenses, equivalent to over 50% of China’s 2023 trade surplus, and they are linked to higher employment and economic growth.
