How Europe Can Meet Hydrogen Fuel Mandates Without Hydrogen Fuels
When I published my recent piece on Germany’s bid to double hydrogen-based fuel targets to try to justify already built and already stranded hydrogen infrastructure, readers raised important questions about compliance mechanics. One pointed out that the 1% RFNBO subtarget can be met by replacing grey hydrogen in refineries rather … [continued]

Hybrid Electric Ships and the Alcohol Fuel Convergence
In recent weeks I have published on the end game economics of maritime fuels, why decarbonizing maritime shipping won’t be inflationary, and why most battery electric shipping studies were already obsolete. Those pieces generated a steady stream of questions that were more specific than the original arguments, as well as … [continued]
