The tiny new fuel cells, developed by researchers at the Nuclear Futures Institute at Bangor University in Wales, are roughly the size of poppy seeds, which are around 0.04 inch (1 millimeter) across.

When burned or used in fuel cells, hydrogen produces nothing but water, making it an ideal candidate for reducing global carbon emissions. Yet, most of the hydrogen produced today comes from ...

H2SITE has produced pure hydrogen from ammonia on board, through a process called “Ammonia cracking”, using its integrated membrane reactor technology. Connected to a PEM fuel cell, hydrogen ...

The fuel, called high-assay low-enriched uranium, or HALEU, is enriched to levels of up to 20%, compared with about 5% for the fuel that powers most existing reactors.
