Two more hydrogen bus trial failures crossed my screen this morning, so I thought I’d share. Both are in Europe, but while one is in the capital of the EU, the other is across the Channel in the heart of the United Kingdom’s oil and gas industry. While I’m at … [continued]
Electrathon America is an organization that provides hands-on opportunities for participants to learn about STEM principles as they design and build an electric vehicle for competition.

The leading Chinese solar manufacturer LONGi aims to shake up the global solar industry with a new 24.8% efficiency rating for its Hi-MO 9 solar module.
The UK firm Highview Power is bringing its liquid air energy storage system to four locations in Scotland and England, providing long duration storage for wind and solar energy.
About a dozen years ago, more battery-based energy storage projects began to be completed, which was exciting because they were, and continue to be, a solution to the “intermittency problem.” Sunshine and wind are not available 24/7, so it is necessary to store some solar and wind power electricity for … [continued]
