The Clean Energy Future Hawaiʻi Can Actually Build: New TFIE Strategy White Paper

The newly published white paper began with a question that persisted because of how clearly island systems expose the realities of energy. Can Hawaiʻi, an isolated archipelago with no continental grid behind it and a long dependence on imported fuels, build an energy system that is cleaner, more resilient, more … [continued]

Enhanced Geothermal Systems Could Expand Geothermal Power Generation

The first large-scale commercial enhanced geothermal system (EGS) power generator in the United States is under construction with the company reporting in our generator survey that it plans to bring the project online in June 2026. Below, we examine what enhanced geothermal systems are and how they differ from conventional geothermal systems. What is … [continued]

Deutsche Energieflüsse in einem Szenario mit ausschließlich erneuerbaren Energien und begrenztem Wasserstoffeinsatz, vom Autor.

Unter Druck gesetzter Stahl, fehlende Nachfrage: Deutschlands Wasserstoff-Backbone in den Energieflüssen*

Das deutsche Wasserstoff-Backbone ohne Kunden oder Lieferanten — eine Pipeline von nirgendwo nach nirgendwo — ist realer Stahl im Boden, unter Druck gesetzt und als unvermeidlich verteidigt, doch sie wird für ein Energiesystem gebaut, das sie nicht braucht. Diese Aussage klingt provokant, bis die Energieflüsse vollständig offengelegt werden. Betrachtet man … [continued]
