Germany’s Hydrogen Refueling Network Looks Impressive Until You Do The Math

Someone recently pointed me at a chart published by H2 Mobility that shows hydrogen dispensed per month across its German refueling network climbing steadily over time. The chart is visually persuasive. The blue area rises from near zero in 2017 to roughly 59 tons per month in early 2026. It … [continued]

Wind on Oʻahu: A Modest but Valuable Complement to Solar

Any serious discussion of renewable energy on Oʻahu should begin with a clear understanding of how much electricity the island actually needs once fossil fuel end uses are electrified. Earlier analysis constructed a fully electrified civilian energy Sankey for Oʻahu that removed overseas aviation fuel, international maritime bunkering, and military … [continued]

IAA Will Ensure Most EVs Sold in Europe Will Have Batteries Made in the EU,…

T&E’s reaction to the proposed Industrial Accelerator Act. Local content rules are a positive step for Europe’s battery industry as corporate cars will be required to have local batteries. But extending EV purchase subsidies to all FTA countries and requiring non-strategic components to be local, undermines its effectiveness. From 2027, … [continued]

Unlocking Vehicle-to-Grid at Scale

Why EU type approval is the missing lever to make every EV a grid asset. In 2024, T&E highlighted the potential of Vehicle-to-Grid (V2G), and bi-directional charging of Electric Vehicles (EVs). EVs are ‘Batteries on Wheels’, delivering flexibility benefits for the electricity grid, supporting the integration of more renewables, and delivering … [continued]

Can Shipping’s Greenhouse Gas Emissions Be Captured At The Funnel?

An evidence based assessment of key barriers to Onboard Carbon Capture and Storage, and its potential for maritime decarbonisation. As shipyard orderbooks are full of fossil-powered vessels, and uncertainty remains about the speed of green fuels uptake, the shipping industry is also looking at a wide range of alternative solutions. … [continued]

Timeline of UK Hinkley nuclear reactor delays against 75% grid decarbonization with renewables by author

While Hinkley Nuclear Was Being Built, The UK Grid Decarbonized

The latest announcement about Hinkley Point C was predictable. The first reactor at the plant in Somerset is now expected to begin generating electricity in 2030. The cost estimate has climbed again, now reaching roughly £35B in 2015 pounds or about £49B in current money according to Electricité de France. … [continued]
