Honda and General Motors will jointly produce pollution-free hydrogen fuel cell power systems in the United States from around 2020, despite President Donald Trump’s promises to dismantle US environmental regulations intended to spur green car demand.

At a briefing in Detroit, GM executive Mark Reuss said the fuel cells could be used in autonomous vehicles, as well by ride-sharing companies, such as GM affiliate Lyft. He also said fuel cells could have aerospace and military applications.

The companies on Monday said they will invest $85 million to add a production line at a GM battery plant in Brownstown, Michigan, and create 100 jobs. The fuel cell production line will be partly automated and is designed to be quickly scaled up if demand warrants.

Metallic hydrogen, once theory, becomes reality: Harvard physicists succeed in creating ‘the holy grail of high-pressure physics’

metallic hydrogen

The material – atomic metallic hydrogen – was created by Thomas D. Cabot Professor of the Natural Sciences Isaac Silvera and post-doctoral fellow Ranga Dias. In addition to helping scientists answer fundamental questions about the nature of matter, the material is theorized to have a wide range of applications, including as a room-temperature superconductor. The creation of the rare material is described in a January 26 paper published in Science.

“This is the holy grail of high-pressure physics,” Silvera said. “It’s the first-ever sample of metallic hydrogen on Earth, so when you’re looking at it, you’re looking at something that’s never existed before.” [Read more…] about Metallic hydrogen, once theory, becomes reality: Harvard physicists succeed in creating ‘the holy grail of high-pressure physics’
