Forward Festival, which will see the likes of Lorde, Little Simz, Tems & Goldie perform, is using pioneering green hydrogen technology (GeoPura) and a fleet of scalable battery to power the event.
The changes have been made possible with funding from a Clean Power Pilot led by the West of England Combined Authority (Weca), running this summer.
Helen Godwin, Weca mayor, said: “After another exceptionally hot and dry summer, everyone can see how our climate is changing.
“Here in the West of England, we’ve brought together our brilliant creative industries and clean energy sectors to try to help tackle the climate crisis and clean up our air.”
“We’ve always been a region that cares about our environment, cares about clean energy, about clean air. But we also love to have a good time,” said Godwin.
She added that producing dirty air affects people’s health.
“We’re trying to think of innovative clean ways that we can do that better,” she added.
Weca’s ambition is to expand the model in 2027, extending it to multiple sectors and paving the way for adoption elsewhere in the UK and internationally.
