Chatgpt generated island town showing the solar-and-storage backbone of Hawaiʻi’s broader transition.
Oʻahu was the test case, but it was never the whole question. The real question for Hawaiʻi was always whether the same logic that makes decarbonization viable on the most populous island would also hold across the rest of the inhabited archipelago. If Oʻahu could get to a clean, resilient, … [continued]
Chatgpt generated: Workers installing solar and grid infrastructure representing the execution phase of the transition.
This is the culminating article in a series exploring from the outside a decarbonization solution set and coarse roadmap for Hawaiʻi. It is a set of possible next actions that a Hawaiian agency, utility, authority, or coalition could undertake if the roadmap outlined in this series is worth exploring further. … [continued]
What follows is a draft roadmap for a decarbonized O’ahu. This roadmap does not appear out of nowhere. It follows a long chain of analysis that rebuilt Oʻahu’s energy system piece by piece. Earlier articles stripped away overseas aviation fuel, international maritime bunkering, and military demand to isolate the island’s … [continued]
Cost challenges with LNG to hydrogen import scenario for Hawaii, AI assistance with image generation
Hawaiʻi’s debate over importing liquefied natural gas has turned on a state study that was supposed to show whether LNG could lower electricity costs on Oʻahu while serving as a bridge to a cleaner system later. The scenario sold for the past year turned out to be based on a … [continued]
The clean energy future for Oʻahu is no longer blocked by missing technology. The architecture is already visible. Once overseas aviation fuel, international bunkering, and military energy use are taken out of the frame, and once transportation, buildings, and industry are electrified, the civilian Oʻahu system settles into roughly 6,000 … [continued]
Chatgpt generated: Sustainable aviation fuel storage and fueling at Honolulu Airport for long-haul flights.
The final piece of Hawaiʻi’s decarbonization puzzle is not on Oʻahu’s domestic grid. That part of the work is already largely bounded. In the earlier articles in this series, I stripped out overseas aviation fuel, ocean-crossing ship bunkering, and military energy use, then electrified ground transportation, local marine transport, buildings, … [continued]
Chatgpt generated: Solar panels across rooftops and parking canopies representing the dominant energy source for Oʻahu.
The debate over LNG in Hawaiʻi persists because it sounds like a practical answer to a familiar problem. Oʻahu still relies heavily on imported fuel for electricity, so a different imported fuel can appear to be a reasonable bridge. LNG is marketed as dispatchable, cleaner than oil, and compatible with … [continued]
Chatgpt generated a visual timeline of SunLine’s hydrogen refueling systems across multiple generations.
SunLine Transit Agency, which provides transportation for the large western California county that includes Palm Springs and Coachella, has spent a quarter century doing more than almost any transit agency in North America to try to make hydrogen buses work. It started hydrogen production and dispensing around 2000, has cycled … [continued]
Chatgpt generated California transit depot where hydrogen remains a niche beside a much larger battery electric fleet.
Ballard Power and New Flyer announced what sounds at first like a market-making agreement, a commercial arrangement for 500 fuel cell engines, or about 50 MW of modules, for hydrogen transit buses starting in 2026. On the surface, that reads like the kind of order that only appears when a … [continued]
Chatgpt generated: Alberta homes in winter, where higher natural gas prices increasingly affect heating costs.
Alberta has spent years arguing that natural gas was undervalued because it was trapped in a basin with too few outlets. That argument was always partly right. The Alberta Energy Regulator says the average AECO-C price was only $1.45/GJ in 2024, down 47% from 2023’s global European Energy crisis prices, … [continued]
