SOEC* achieves a 30% cut in input power during hydrogen production

●Since the SOEC operates at 600~800℃ high temperature and thermal

energy can also be utilized for water electrolysis besides electric power, a

more efficient hydrogen production system is realizable.

Advancing Society’s Realization of Sustainable Energy

In nuclear power, we are committed to site stabilization at Fukushima Daiichi, and through synergies with WEC, we pursue the world’s highest levels of safety. We aim to achieve “green energy.“ In thermal power, still the main source of electricity, we are pursuing further efficiency improvements and deploying carbon capture technologies to realize zero emissions. We are also promoting renewable energy sources: hydro, geothermal, solar and wind power. Through energy storage technologies that take advantage of the characteristics of pumped storage power generation, rechargeable batteries, hydrogen production and other systems, and by promoting advanced energy management technologies and high-efficiency power distribution systems, we will continue to contribute to increased adoption of renewable energy and stabilization of the power system.
