Momentum is continuing to build behind the development of clean hydrogen production amid the global energy crisis, with electrolyser manufacturing expected to grow strongly and pilot projects proliferating in new applications such as steel and transport, a new International Energy Agency report says.

The energy crisis underscores the need for policies to align energy security needs with climate goals. Low-carbon or “clean” hydrogen, which can be produced from nuclear reactors, can contribute to energy security by decreasing dependency on fossil fuels, either by replacing fossil fuels in end-use applications or by shifting fossil-based hydrogen production to renewable hydrogen.

The development of an international hydrogen market can additionally add to the diversity of potential energy suppliers, improving energy security for energy importing countries in particular.
