Today, with the commencement of these hydrogen truck trials, we are proud to further this legacy by pioneering the transition to clean, zero emission energy for long haul transportation.

On the lower right is an artificially colored light emission intensity map of the same region ... which is about the size of 11 hydrogen atoms arranged in a line — they behave in a unique way, ...

The Five-hundred-meter Aperture Spherical radio Telescope (FAST) was used to study the emission properties of three long-period pulsars: PSR J1945+1211, PSR J2323+1214, and PSR J1900−0134.

Stellantis said the extended compliance period on carbon emission targets was a "meaningful step in the right direction" to preserve the auto industry's competitiveness, while remaining committed ...

A U.S.-headquartered manufacturer of green hydrogen fuel cells wants to build what the company’s president called “multi-gigawatt” electrolyzer projects in India. Sanjay Shrestha ...
