On its most basic level, hydrogen fuel contains less energy per unit volume than the fossil fuels it would be replacing. Therefore, according to theUS Department of Energy(DoE), “transporting, storing, and delivering it to the point of end-use is more expensive on a per gasoline gallon eq...

“The consideration of on-site hydrogen production, gaseous hydrogen delivery, or liquid hydrogen delivery depends on the space available on the fleet fueling site, size of the fleet, and price of electricity at the site,” said Natalie Moya, communications manager for Cummins New Power. Green F...
solar and nuclear energy in the fight to reduce carbon emissions, but it seems we’ve forgotten about hydrogen fuel. Hydrogen — made by splitting water — was considered energy-intensive and expensive to make. But new plans for hydrogen fuel cells in cars show hydrogen made using renewable en...
①Amid the excitement, it is worth being clear about what hydrogen can and cannot do. ②Japanese and South Korean firms are keen to sell cars using hydrogenfuel cells, but battery cars are roughly twice as energy efficient. ③Some European countries hope to pipe hydrogen into homes, but heat...
