Infrastructure firm Acciona is operating Chile’s “first” hydrogen fuel cell generator at a construction site near the world’s largest underground copper mine.

The pilot generator is powering a construction site that is expanding the Carén reservoir, which supplies state-owned copper producer Codelco’s El Teniente mine.

According to Acciona, the 80kW GEH2 generator from France’s EODev will reduce fossil fuel consumption by 5,067 litres and prevent 13.6 tonnes of carbon dioxide emissions per quarter.
