Ineos has held initial talks with Rolls-Royce on using its nuclear technology to potentially provide zero-carbon energy to the Grangemouth refinery.
The engine maker is one of several companies hoping to use experience with mini nuclear reactors for submarines to build the next generation of power sources, while the chemicals group is looking to decarbonising its massive facility on the Firth of Forth.
Ineos is in the early stages of moving to hydrogen power at the Grangemouth plant, but doing this in a 'green' way requires large amounts of renewable electricity, so it is currently considering wind and nuclear options.
