Ireland’s goals to host the cloud and harvest the wind

While Ireland seeks to promote hydrogen in transport, capital expenditure and other costs remain a formidable barrier

Emmet Lagan, director of Lagan Energy Engineering.

In our work developing Green Data Valleys across Ireland exploring co-located electrolysers and the integration of renewables with digital infrastructure one insight is becoming increasingly clear: while hydrogen in transport continues to dominate headlines, the real cost barrier, especially capital expenditure, remains formidable.

Yet a growing consensus is emerging among digital infrastructure architects: the first real movers in clean hydrogen may not be on wheels, but in racks. The tipping point in the hydrogen economy could come not from mobility, but from megabytes.
