ILE was incorporated in January 2020.

In 2019, ITM signed a collaboration agreement with Iwatani Corporation of America, a wholly owned subsidiary of Japan's Iwatani Corporation, for the deployment of multi megawatt electrolyser-based hydrogen energy systems in North America.

In 2020, ITM enacted a third fundraise, raising £172 million in equity that included a £30 million investment from Snam S.p.A.
