A project manager for the Los Alamos National Lab Fuel Cells and Vehicle Technology Department says that they are working on getting hydrogen-powered commercial semi-trucks on the roads. 

"This is not just a laboratory research project," Rod Borup, project manager with LANL’s Fuel Cells and Vehicle Technology department, said in a KRQE article. "The whole goal of this project is to get them out there and commercialized." 

According to its site, the Los Alamos National Lab's work with hydrogen dates back to the Cold War and the creation of hydrogen bombs, but the lab is now working to use that technology for transportation. 

The laboratory site explains that the development of fuel cells and hydrogen as an energy source began with "the utilization of expertise related to hydrogen gained from Project Rover, a program aimed at developing a nuclear-powered rocket."

Then in 1977, the Department of Energy awarded the first the first Fuel Cells for Transportation program to LANL, according to the program's website. 

The LANL's fuel cell program is also working alongside the Department of Energy, with hopes of seeing hydrogen-fueled vehicles including buses, cars and ferries a reality, according to KRQE.  Transitioning to use of semis that use hydrogen fuel may be able to cut emissions down on greenhouse gases by 20% in the U.S.
