He has also called for investment in technologies like carbon capture.

SMRs are just one of several wildly overhyped false promises on which the world is poised to spend hundreds of billions of dollars by 2040, including hydrogen energy and direct air carbon capture.

These projects, known as carbon capture, usually focus either on capturing emissions at source or pulling them from the air.

There are already much more developed carbon capture technologies which take carbon directly out of the air – but Dr Paul Halloran who leads the SeaCURE project tells me that using water instead has it's advantages.

"Carbon removal is necessary. If you want to reach net zero emissions and net zero emissions is needed to halt further warming," says Dr Oliver Geden who's part of the Intergovernmental Panel on Climate Change and an expert in carbon capture.
