Spain uses hydrogen to generate electricity for national grid

A giant engine powered entirely by pure hydrogen has successfully generated electricity for Spain's national grid in what its manufacturer describes as a world first for large scale power generation.

Developed by a Finnish technology company in Vaasa and tested in northern Spain the technology is intended to show how hydrogen could one day be used in power plants supplying hundreds of megawatts of electricity to national grids without carbon emissions.

The company developed the technology at its Sustainable Technology Hub in Finland where it designs and builds engines and energy systems that are exported around the world.

Hydrogen is increasingly being explored as a way to solve one of the biggest challenges facing renewable energy system.
