Yonekurayama Electric Power Storage Technology Research Site (Kofu City) where Yamanashi Prefecture and TEPCO Energy Partners conduct demonstration tests of power supply and demand adjustment with green hydrogen
On the 17th, Yamanashi Prefecture and TEPCO Energy Partner (EP) and others used the green hydrogen production device "P2G (Power to Gas) System" at the Yonekurayama Electric Power Storage Technology Research Site in Kofu City to enter the power network. Announced that it will start a verification test to adjust the supply-demand balance. Examine the suitability of the country's power regulation market. Governor Kotaro Nagasaki emphasized that "it will be the key to open the door to renewable energy as the main power source."
Governor Nagasaki, President Nobuhide Akimoto of TEPCO EP, and President Ken Ichimura of Energy Pool Japan (Tokyo, Minato) of power supply and demand management held a press conference at the Yamanashi Prefectural Office.

Yonekurayama's P2G, which produces hydrogen by solar power generation, uses a water electrolyzer called a solid polymer type, and has the feature of responding to commands to increase or decrease the output in seconds. By controlling in combination with IoT devices, it is expected to play a role in adjusting the constantly changing supply-demand balance in the power network.
Since the amount of power generated by renewable energy is unstable, output control is performed when the amount of solar power generation is too large in areas such as Kyushu. Mr. Nagasaki said, "The Yamanashi model P2G can produce hydrogen using the surplus electricity of renewable energy. I want to prove that it can solve the problem of output control and contribute to the main power source of renewable energy."
Hydrogen produced by P2G can be used in factory boilers, etc., and has the advantage of reducing the use of fossil fuels such as heavy oil. President Akimoto pointed out that "development of hydrogen technology needs to be tackled by the whole country. If demand control (P2G, etc.) becomes widespread, it can contribute to the stable supply of electric power." President Ichimura said, "It will lead to local production for local consumption of electricity."
