I’m preparing to speak to engineers at GE Vernova during Engineering Week at the request of Cornelis Plet, CTO of GE Vernova Grid Systems Integration. It is a useful moment to step back and look at a class of technologies that rarely make headlines but quietly shape how modern power … [continued]
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]
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]
Any discussion of solar power on Oʻahu has to begin with the amount of electricity the island actually needs in a fully electrified system. Earlier analysis stripped out aviation fuel for overseas flights, fuel bunkered for ships leaving the islands, and military fuel use. It also electrified transportation, buildings, and … [continued]
Zachary Shahan’s review of the Bluetti Elite 400 battery made me smile, I have to admit. Let me explain. Perhaps you might smile as well. I have been interested in getting a solar power system for a very long time. So long, in fact, that I remember talking about such … [continued]
Energy discussions about Hawaiʻi often begin with the largest numbers on the chart. Aviation fuel, maritime bunkering, and military logistics dominate many of the data tables that describe the state’s energy system. When those numbers are placed on a single chart, the scale of the challenge appears enormous and the … [continued]
In my previous assessments of Hawaiʻi’s energy system, I examined specific infrastructure decisions such as proposed LNG imports and the role of legacy petroleum assets. Those analyses focused on timing, economics, and the risk of locking in fossil pathways that do not align with the state’s statutory commitment to 100% … [continued]
In the past week I had the opportunity to deliver the same presentation on the global acceleration to clean technologies and decarbonized solutions to two different audiences, one from a stage keynoting the 2026 Clean Energy Summit in the Vancouver Metropolitan area, and one virtually. Both were Canadian audiences. The … [continued]
Every time hydrogen is critiqued as an energy carrier for the power sector, the same question reappears. If not hydrogen, where does long duration storage come from? I received it related to my recent critique of Germany’s attempt to force the EU to double green hydrogen and synthetic fuel quotes … [continued]
The US automaker Rivian has partnered with the clean energy software firm EnergyHub to connect more EV drivers with their local virtual power plant.
