Vattenfall and Samuel L Jackson’s seaweed snack is grown on wind farms

Sweden – Swedish energy company Vattenfall has teamed up with actor Samuel L Jackson to launch Wind Farmed Seaweed Snacks, a limited-edition delicacy grown at the Vesterhav Syd offshore wind farm in Denmark.

The collaboration, part of Vattenfall’s Win@sea project, shows how wind farms can simultaneously generate fossil-free electricity, produce food and help regenerate the marine environment. 

The seaweed is cultivated on lines between the turbines, absorbing carbon dioxide and excess nutrients before being harvested and processed into snacks. While not a commercial product, the limited batch has been shared with select recipients. 

‘For me, it’s about the world we’re leaving behind for the next generation,’ says Jackson. ‘These offshore wind farms aren’t just producing fossil-free electricity; they also create a habitat for sea life to grow. That’s next-level thinking.’ 

Helle Herk-Hansen, Vattenfall’s head of environment, adds, ‘The Wind Farmed Seaweed Snacks demonstrate that our fossil-free electricity infrastructure can coexist with nature. And with an advocate like Samuel L Jackson, we had the opportunity to share that message with more people.’
