Why Shipping Is Quietly Aligning On Methanol & Hybrid Electric Systems
Shipping decarbonization is often discussed as a contest of fuels, but the more revealing story is how capital, engineering effort, and orders are actually moving. Over the past three years, the maritime sector has been forced to reconcile ambitious fuel narratives with operational reality. Engine manufacturers and ship buyers are … [continued]

Dijon is a useful hydrogen transportation case study because it was serious, early, and well funded. This was not a symbolic pilot. The city committed real capital, built infrastructure, signed supply agreements, and intended to operate hydrogen vehicles at scale across buses, refuse trucks, and light municipal fleets. The intention … [continued]

From Fossil To Renewable: California’s Diesel Transition & The Future Of Refineries
In a recent article, California Refineries Close as Gasoline Demand Slips into Permanent Decline, I wrote that diesel consumption in California had not declined even as gasoline demand slipped. Jeremy Martin from the Union of Concerned Scientists reached out to me to point to some data I’d missed. I reviewed … [continued]

U.S. Biodiesel & Renewable Diesel Imports Fall Sharply in 2025 after Tax Credit Change
U.S. imports of biodiesel and renewable diesel significantly decreased in the first half of 2025 (1H25) compared with the same period in previous years. This decline is primarily due to the loss of tax credits for imported biofuels and generally lower domestic consumption of these fuels. Renewable diesel and biodiesel … [continued]
