Hidrogenii, a joint venture between US green hydrogen company Plug Power and chemical manufacturing firm Olin Corporation, has turned on a 15-tonnes-per-day hydrogen liquefaction plant in St Gabriel, Louisiana.

Hidrogenii was established to build and operate the facility, which is now one of the largest electrolytic hydrogen liquefaction plants in North America.
