Hydrogen Buses Work. That Is Not The Procurement Question.

8 min read

Hydrogen buses are real. They can carry passengers, complete routes, refuel, and operate in public transit fleets. That much has been demonstrated often enough that it is no longer the useful question. The useful question for transit agencies is whether hydrogen is a better procurement choice than battery-electric buses once … [continued]

Cummins, Alstom, and the Long Tail of Hydrogen Mistakes

10 min read

Both Cummins and Alstom lost with hydrogen, but they lost in different ways, and that difference matters. Cummins spread capital and management attention across a broad set of hydrogen pathways, including fuel cells and electrolyzers, then ran into the market reality that hydrogen demand for energy applications was weaker, slower, … [continued]

Why Molecular Solar Thermal Is Great Chemistry And Bad Energy Hype

16 min read

Every few years, a chemistry paper wanders out of the lab, passes through a university press office, gets dressed up by a science news site, and lands on social media as if humanity is one strained molecule away from solving energy storage. The latest example is Molecular Solar Thermal storage, … [continued]
