JERA Co and Mitsubishi Heavy Industries have been granted funding, under the Green Innovation Fund programme of Japan’s New Energy and Industrial Technology Development Organisation (NEDO), to conduct a project to develop and demonstrate a technology to increase the ammonia co-firing rate at coal-fired boilers.
Using ammonia enables efficient, low-cost transport and storage of hydrogen. In addition to this role as an energy carrier, it can also be used directly as a fuel in thermal power generation, and does not produce carbon dioxide when burned. Ammonia is expected to offer great advantages in reducing greenhouse gas
This project aims to develop an ammonia single-fuel burner suitable for coal-fired boilers and to demonstrate operation of the burner in field tests with working boilers. The term of the project is approximately 8 years, ending in 2028.
By financial year 2024, JERA and MHI expect to develop a new burner capable of single-fuel ammonia combustion, and to draw up a plan to demonstrate its use in actual boilers. Based on the results, the two companies will decide whether to install the burners at JERA's coal-fired boilers made by MHI. For the plant demonstrations, JERA and MHI plan to verify co-firing with at least 50% ammonia at two units with different boiler types by 2028.
Under its ‘JERA Zero CO2 Emissions 2050’ objective, JERA has been working to reduce CO2 emissions from its domestic and overseas businesses to zero by 2050. Under its ‘Mission Net Zero’ declaration, MHI intends to promote the energy transition in co-operation with partners around the world, and contribute to achieving a carbon-neutral society through the collective efforts of the group.
