The British government predicts that heating homes with hydrogen could become mainstream within decades, with technical costs falling as sharply as wind energy.

To accelerate the transition from fossil fuels, the government will fund the first British families to use this new source of energy for heating entirely, Anne-Marie Trivien, Britain's energy minister, said in an interview.

Trivillian predicts that the cost of hydrogen technology will fall as much as offshore wind power has done over the past decade. This will happen once the technologies used to produce hydrogen and carbon capture and use are verified on a large scale, she said.

In addition to heating homes, hydrogen technology is also expected to help decarbonize heavy industries such as steel and cement.

"We will see a tipping point that will absolutely lower prices and make them the mainstream part of our future world," Trivien said. "
