District Cooling From the Pacific: A Targeted Efficiency for Oʻahu

11 min read

The starting point for evaluating seawater air conditioning on Oʻahu is the fully electrified energy system for the island that has been developed through the earlier Sankey analysis. In that framework the island’s civilian energy system excludes overseas aviation fuel, maritime bunkering for ships crossing the Pacific, and military energy … [continued]

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

11 min read

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

10 min read

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]
