Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready for use in a decade.
Tom McGuire, who heads the project, said he and a small team had been working on fusion energy at Lockheed’s secretive Skunk Works for about four years, but were now going public to find potential partners in industry and government for their work.
Initial work demonstrated the feasibility of building a 100-megawatt reactor measuring seven feet by 10 feet, which could fit on the back of a large truck, and is about 10 times smaller than current reactors, McGuire told reporters.
In a statement, the company, the Pentagon’s largest supplier, said it would build and test a compact fusion reactor in less than a year, and build a prototype in five years.
Lockheed’s work on fusion energy could help in developing new power sources amid increasing global conflicts over energy, and as projections show there will be a 40% to 50% increase in energy use over the next generation, McGuire said.
Compact nuclear fusion would produce far less waste than coal-powered plants since it would use deuterium-tritium fuel, which can generate nearly 10 million times more energy than the same amount of fossil fuels, the company said.
Ultra-dense deuterium, an isotope of hydrogen, is found in the earth’s oceans, and tritium is made from natural lithium deposits. It said future reactors could use a different fuel and eliminate radioactive waste completely.
Lockheed said it had shown it could complete a design, build and test it in as little as a year, which should produce an operational reactor in 10 years, McGuire said. A small reactor could power a US navy warship, and eliminate the need for other fuel sources that pose logistical challenges.
