Why Hydrogen Transit Often Emits More Than Diesel Once You Count Everything
The discovery, late in the year, that yet another hydrogen transit scheme turned out to be high emissions rather than low emissions was not surprising, but it was clarifying. The Dijon hydrogen bus project followed the same pattern seen repeatedly over the past several years. It was presented as zero … [continued]

Big Loads, Small Loads, & A Changing Grid: A Better Path for Scope 2 Accounting?
An advocacy piece published by WattTime and REsurety was brought to my attention because it reflects the tension building around the proposed revisions to the Greenhouse Gas Protocol’s Scope 2 accounting rules. These rules are not American regulations. They are global and voluntary, governed by the World Resources Institute and … [continued]

Hydrogen’s Seven Missing Pieces
I wrote another technoeconomic assessment of why hydrogen will not be cheap, and the reaction from hydrogen advocates was familiar. They focused on small pieces of the analysis and treated each point as if it existed in isolation. That pattern confirmed something important. The debate is not about one technology … [continued]

The Short List of Climate Actions That Will Work
A few months ago, I was invited by Dr. Sebastian Husein of the Battery Centre Twente to speak at the University of Twente’s 2025 Climate Event, a hybrid discussion with multiple speakers engaging with an audience of academics in the Netherlands and neighboring countries. That event occurred on November 5th, … [continued]

Why Hydrogen Isn’t Cutting Costs Like Solar or Batteries
After publishing the summary of the study that assessed 2,000 hydrogen projects worldwide, one finding stood out. Across the total spectrum of use cases, electrification provided roughly 80% better emissions reductions than hydrogen. The data also showed that the overall climate benefit of hydrogen, once all losses and logistics were … [continued]
