Our February update on EV sales shows: Australian plugin penetration grew from 16% in January 2026 to about 19% in February. That is a sales total of 11,100 battery electric vehicles (BEVs) and 5,854 plugin hybrid EVs (PHEVs). Almost 17,000 Australian motorists joined the electric vehicle ecosystem, a significant increase … [continued]
Buffering batteries placed near transmission constraints are rarely listed among grid enhancing technologies. The usual list includes advanced conductors, dynamic line rating, and power flow control devices. All of those technologies increase the instantaneous capacity of transmission lines. Batteries do not do that. A battery cannot turn a 500 MW … [continued]
Dynamic line rating can produce large savings in some parts of the electricity system. In other cases it reveals that operators had been overestimating how much cooling transmission lines receive from the surrounding air. Both outcomes matter. Dynamic line rating replaces assumptions with measurements and forecasts about what transmission lines … [continued]
The recent investigative reporting by Swedish Television and Norway’s NRK into the fuel cell supplier PowerCell has opened a window into the Vestfjord Lofoten hydrogen ferry project that Norway has been building toward for years. The journalists focused on a specific claim about durability. Internal tests suggested that the fuel … [continued]
The series examining Oʻahu’s energy transition has followed a consistent structure. It began by defining the island’s fully electrified energy system and stripping away energy uses that do not serve the civilian economy. Aviation fuel for flights leaving Hawaiʻi, maritime bunkering for ships crossing the Pacific, and military energy consumption … [continued]
Electricity demand is rising as transport, heating, and industry electrify, with additional growth coming from data centers and expanding industrial loads. The transmission network that moves electricity was built over many decades, but expanding it has become increasingly difficult. Building new transmission lines often takes ten to fifteen years once … [continued]
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]
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]
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]
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]
