# Japan industrial and thermal power decarbonization > Live situation record from CLSTR: https://clstr.news/situations/japan-industrial-and-thermal-power-decarbonization > Updated: 2026-09-16T00:15:30.000Z. Sources: 4. Developments: 2. Japan is advancing various technological initiatives to decarbonize its industrial and power sectors. Efforts include the expansion of the waste heat power generation market, which is projected to grow at a compound annual growth rate of 13.7% between 2025 and 2035. This growth is supported by the government’s Green Transformation (GX) strategy and the use of Organic Rankine Cycle technology to convert unused process heat into electricity. Simultaneously, the nation is transitioning from technical demonstrations to the commercial implementation of ammonia co-firing in thermal power plants. Following successful tests at the Hekinan Thermal Power Station, utilities like JERA aim to begin commercial-scale operations with a 20% ammonia substitution rate by fiscal year 2029. This transition involves securing international supply chains for low-carbon ammonia and developing technology to potentially increase co-firing rates to 50%. ## Timeline ### 2026-09-16: Japan expands ammonia co-firing for thermal power decarbonization Japan is moving toward commercial ammonia co-firing in thermal power plants. JERA aims for 20% ammonia substitution by FY2029, supported by new supply chains and technology to reach 50% co-firing. 3 sources. https://clstr.news/cluster/japan-expands-ammonia-co-firing-for-thermal-power-decarbonization ### 2026-09-10: Japan waste heat power market to grow via industrial decarbonization Japan's waste heat power generation market is projected to grow at a 13.7% CAGR through 2035, driven by industrial decarbonization and advancements in Organic Rankine Cycle technology. 3 sources. https://clstr.news/cluster/japan-waste-heat-power-market-to-grow-via-industrial-decarbonization --- Cite as: Japan industrial and thermal power decarbonization.
