Scaling renewable hydrogen in China's emission-intensive chemical sector could eliminate well over 610 million tonnes of carbon annually compared to 2022, while reducing exposure to oil and gas market volatility.
This would require technological upgrading and a structural shift in production, with the largest abatement opportunities lying in substituting fossil-based with renewable hydrogen in oil refining and in new, heavily invested coal-based chemical industries, including ammonia and methanol.

Closing the temporary cost increase of renewable production – the green premium – through targeted, feedstock-specific strategies is key to scaling renewable chemicals in the near term.
Current cost gaps vary: from none to USD 360 per tonne for ammonia, and from around USD 230 to USD 610 per tonne for methanol, with the use of directly captured carbon driving higher costs in the latter pathway. Renewable ammonia is therefore closer to parity, while biomethanol and bio-e-methanol can become cost-competitive where affordable sustainable biomass is available.

Establishing reliable demand through strong policy signals is critical to sustaining investment in green hydrogen, ammonia and methanol.
Project pipelines in China indicate a slowdown in investments from 2027, signalling fragile market confidence without a durable policy framework. Mandatory sourcing quotas for renewable-based chemicals and tightened carbon intensity rules across the supply chain can provide revenue visibility and anchor demand. In parallel, clearer green standards and carbon taxonomies would reduce supplier uncertainty and create lead markets for early deployment.

Green hydrogen is a key pillar of China's 15th Five-Year Plan, strategically positioned to drive industrial competitiveness and energy system transformation.
Its inclusion, alongside a dedicated national hydrogen fund, signals stronger state backing for building a scaled hydrogen economy and associated supply chains. Within this framework, green hydrogen is also an important lever for reducing dependence on fossil imports and accelerating the shift away from high-carbon coal-to-chemical pathways. Sustained national coordination will be critical to scale projects, connect renewable-rich regions with industrial hubs and translate policy momentum into structural substitution of polluting coal-based chemical production, particularly given the short-term and fragmented nature of current provincial support schemes.
Renewable hydrogen for chemical sector decarbonisation in China
Agora analysis shows how renewable hydrogen could help China significantly reduce chemical sector emissions while boosting energy security at competitive costs.
Summary
China's chemical industry is the largest in the world, but it is also one of the most carbon-intensive due to its heavy reliance on coal. This report explores how renewable hydrogen can help decarbonise China's chemical sector by replacing coal-based feedstocks in the production of hydrogen, ammonia and methanol. It provides an in-depth assessment of production costs, project development and the 2024 policy landscape shaping China's transition to low-carbon chemicals.
The analysis finds that replacing fossil-based hydrogen with renewable hydrogen across key industrial processes could reduce China's chemical sector emissions by up to 610 million tonnes of carbon dioxide compared with 2022 levels. While green ammonia is approaching cost competitiveness under favourable market conditions, green methanol remains significantly more expensive because it requires both renewable hydrogen and sustainable carbon feedstocks. The report also examines the role of carbon pricing, bio-based alternatives and evolving cost trends in accelerating the adoption of green chemicals.
Beyond economics, the report highlights how the transition to renewable chemicals is reshaping China's industrial geography. Regions such as Inner Mongolia and the northeastern provinces are emerging as leaders in renewable hydrogen-based chemical production, while coal-dependent provinces face increasing risks of carbon lock-in and economic disruption. These regional dynamics underscore the importance of coordinated infrastructure planning and a just transition strategy.
Drawing on the latest available data from 2024, the report concludes that long-term, cross-regional policy support will be critical to scaling China's green chemical industry. It offers evidence-based insights into technology costs, project pipelines and policy developments, providing valuable guidance for policymakers, industry leaders and investors working to accelerate the decarbonisation of China's chemical sector. A technical document detailing methodologies accompanies the report as a separate file.
