Toshiba Corporation, a multinational Japanese conglomerate, has unveiled Japan’s largest alkaline water electrolysis hydrogen (H2) production system.

According to the company, the generator produces approximately 100 Nm3 per hour of H2 – enough to completely fill two fuel cell vehicles (FCVs).

Utilising an alkaline solution at the electrolyte in the H2 producing chemical reaction removes the need to expensive metals in the system’s electrodes, thus creating a cheaper output capacity.

Our new alkaline water electrolysis H2 production system positions us to meet diversifying needs for H2 production

Hiroyuki Ota, General Manager of Toshiba’s Energy Systems & Solutions Company, noted, “In recent years, H2 power has started to prove its value, as can be seen in the increasing use of stationary fuel cells, FCVs and H2 power generation. This is stimulating demand for high capacity H2 production systems in locations like H2 fuelling stations, and for efficient power utilisation on mega solar power plants and wind farms.”

“Our new alkaline water electrolysis H2 production system positions us to meet diversifying needs for H2 production.”

In addition, Toshiba has developed a H2 production system with a next-generation solid oxide electrolysis cell (SOEC), which is suited to high temperature, low power H2 production. The Japanese corporation is continuing to optimise the system for a range of applications.

Japan is widely viewed as leading the way towards a low-carbon economy, having a total of 74 H2 refuelling stations currently in construction or operation throughout the North Pacific rim country.
