Japan imports first MW-class PEM electrolyser

Tokyo Gas Co. has installed the first megawatt-class (MW) PEM electrolyser in Japan, at the Yokohama Techno Station, with operations scheduled to start in June.

The Neptune PEM electrolyser from ITM Power was made in the UK and shipped to Sumitomo Corporation.

ITM Power describes Neptune as a 2MW ‘plug and play’ electrolyser for small to mid-size projects, designed around its Trident stack platform.

After commissioning, the hydrogen produced will be used in e-methane production.

During demonstration, Tokyo Gas will conduct verification in various operating modes, evaluate equipment performance, and acquire operational know-how of the unit as well as renewable energy power sources, methanation and hydrogen utilisation equipment.

In order to realise clean hydrogen production using water electrolysis, the company said it is “essential” to procure low-cost renewable energy and significantly reduce the cost of water electrolysis, with the size and pressure of equipment increasing, mainly in Europe.

Dennis Schulz, CEO of ITM Power, said, “We are keenly observing the wider developments in Japan, such as the government’s CfD style support scheme, which could see Japan emerge as one of the most fertile countries for green hydrogen projects in the region.”

Together with Miura Kogyo Co., Tokyo Gas has launched the FC-6M fuel cell system (solid oxide), which offers 63% generation efficiency. It will be available from Miura Industry in October.

On March 22, Tokyo Gas and Mitsui & Co. entered into a biomethane agreement, which will see biogas generated from landfills in the US. Around 40,000 metres of biomethane will be liquefied (to LNG), with the first shipment handled at Tokyo Gas’ Ogishima LNG Terminal last week.

The Japanese Government, targeting carbon neutrality by 2050, plans to invest ¥15 trillion ($107.67bn) in hydrogen over the next 15 years under a revision of its Basic Hydrogen Strategy.

The revised target increases the country’s ambitions to boost hydrogen supply from the current level of two million tonnes to 12 million by 2040.
