Business Area


The structural change of energy needs environmental considerations and economic activities. To realize a carbon-neutral society while maintaining a stable power supply, we promote the decarbonization of thermal power generation.

Decarbonization of thermal power generation plants

There is no doubt that renewable energy is essential for achieving a carbon-neutral society. Nevertheless, thermal power generation is becoming more important for its flexibility to satisfy the shortfalls of solar and wind power generation. By converting a conventional fuel to a clean fuel, such as hydrogen and ammonia, decarbonization of thermal power generation plants is possible. Further, by combining the benefits of renewable energy sources with a BESS (Battery Energy Storage System), an energy storage system solutions, extra energy savings can be achieved. Mitsubishi Power develops and offers various technologies for future thermal power generation that will protect our way of life with environmental performance and adjustable capacity.

Mitsubishi Heavy Industries’ Hydrogen Gas Turbine

Replacing gas turbine fuels with hydrogen and ammonia

Achieving net-zero carbon in power supply is necessary for a carbon-neutral society. For this reason, generating power from hydrogen and ammonia is expected to play an important role. We will significantly reduce CO₂ emission by using mixed combustion where a conventional fuel is combined with hydrogen or ammonia, which does not emit CO₂ when burned. Eventually, we will use single-fuel combustion where only hydrogen or ammonia are used.

Optimization of SCR Catalyst Management

“Optimization of SCR Catalyst Management” is a catalyst performance management agency service offered by Mitsubishi Power. As experts in SCR systems, we propose optimal operation and maintenance of SCR systems by the verification of the actual equipment performance based on the periodical catalyst sample testing and the DCS operational data.

Repowering Ageing Plant with Multiple H-25 Gas Turbines

Converting an existing power station to a gas-fired combined-cycle plant with H-25 improves thermal efficiency by 50% and load-following capability.

Fuel Conversion : Reducing Environmental Impact of Power Generation

The global pursuit of the energy transition has generated strong demand for low-carbon and renewable fuel. Yet, thermal power plants still play an important role in maintaining stability of power supplies in many countries around the world. The environmental impact of thermal power plants must therefore be reduced, and Mitsubishi Power has a variety of solutions to do so, including biomass- and ammonia-firing technology as well as solutions to convert existing coal or oil-fired power plants to natural gas.

H-25 Gas Turbines

Users that operate petrochemical plants, paper mills, or similar facilities with coal-fired power generation systems face pressure to adjust and cope with CO₂ emission regulations and carbon taxes. With its H-25 Series of gas turbines optimized for CHP systems, Mitsubishi Power delivers optimized solutions for the on-site power systems of industrial facilities.

BESS (Battery Energy Storage System)

Amid an increased focus on renewable energy sources, BESS (Battery Energy Storage System) compensates for the intermittency of these sources, providing essential value for operators by enabling a stable supply of electricity thus avoiding curtailment of renewable energy and maximizing their revenue.

Hydrogen Gas Turbine

Mitsubishi Power's hydrogen firing technology enables power plant owners to decarbonize their existing Gas Turbine Combined Cycle (GTCC) plants by converting them to hydrogen co-firing, or even making them 100% hydrogen firing in the future. With minimal modifications, Mitsubishi Power supports the transition process by identifying key preparatory and operational steps necessary to decarbonize generation plants while working with customers to create a roadmap for reducing CO₂ emissions.
