The off-grid generator uses green hydrogen in a third-party fuel cell to generate power, which is stored in a sodium battery to provide electricity when needed.

Developed by Sky engineers, the unit is now on trial at its Elstree studios near London to assess its potential as it looks to clean up TV production.

It has not disclosed the system’s power output.

Citing the screen industry environmental group Albert, Sky said around 15% of emissions from high-budget productions come from burning fossil fuels in mobile power use.

“This new technology is a brilliant example of how innovation and sustainability can go hand in hand,” said Sky’s sustainability head, Fiona Ball. “It’s a practical solution that supports our journey to a low-carbon world and shows what’s possible when we embed sustainability into everything we do.”

However, it’s not the first time that hydrogen fuel cells have powered TV and film operations.

UK firm GeoPura has deployed its hydrogen power units for the BBC, the PGA Championships and more, while French technology company EoDev powered a nighttime Netflix shoot in France.

Sky intends to release the findings of its trial, adding another data point to understand where hydrogen may fit in on-location power.
