A power station in the UK has been chosen to be the site of the world's first prototype fusion reactor.
Currently, fusion is only being carried out in experiments.
The West Burton A plant is the one that the government chose.
A spokesman for the UK Atomic Energy Authority said that the plant should be up and running by the early 2040s.
The government had pledged more than 200 million dollars for the program.
Five sites were chosen.
The government stopped assessment of Ratcliffe-on-Soar and started assessment of West Burton after they were named as reserve sites.
The government's choice was announced in a speech by the business secretary.
"Over the decades we have established ourselves as pioneers in fusion science and as a country our ability to surmount these obstacles is unparalleled, and I am delighted to make an announcement of a vital step in that mission," he said.
The fusion energy plant will be the first of its kind and will prove the commercial viability of fusion energy to the world.
The process of fusion takes place inside the sun.
The standard nuclear reactor uses fission to break atoms apart.
Despite being safe and clean, fusion has been difficult to harness.
Some experts believe that existing, proven renewable technologies offer a more economical and timely way of tackling climate change, even though critics say there are still huge hurdles to overcome.
The news was called a "real game-changer" by the Conservative Member of Parliament.
"We're talking billions in investment, we're talking about something that's really globally significant coming to north Nottinghamshire, and what that will do for jobs, investment, really it blows everything else out of the water," he said.
It's like having Toyota or Rolls-Royce come to the constituency, maybe even bigger than that.
Ben Bradley said that he can't wait to power the nation again.
It's new technology, we've proven that it works and we're going to be the hub of research, innovation, commercialising that and selling it to the world.
The coal-fired power station site is set to be closed this year, according to the Local Democracy Reporting Service.
The UK's first fusion reactor will be located at the West Burton site inNottingham.
The area has been associated with energy generation for a long time. This tradition of developing exciting new projects has the potential to transform both the region and the UK's energy supply.
