The technical case for subsea power cables connecting Southeast Asia’s electricity systems has long been established. The next challenge is ensuring that governance arrangements evolve alongside the growing scale and complexity of regional electricity integration. A new analysis from Ember finds that ASEAN’s cross-border electricity ambitions will require stronger regional … [continued]
Renewable energy developers in Colorado are already swarming around the new Power Pathway transmission line, which will loop around 12 counties.
Google Gemini generated this illustration visualizing a critique of EU infrastructure prioritization, contrasting active electricity markets with "hydrogen pipelines from nowhere to nowhere."
The most important policy lesson from the 400 km European hydrogen backbone segment with no suppliers and no offtakers—a pipeline from nowhere to nowhere—I wrote about recently is that decarbonization succeeds or fails on demand realism, not technological aspiration. Europe knew, as early as the late 2000s, that deep electrification … [continued]
California is doing what it has been doing for years — it’s leading on clean energy again. Well, it is leading in one way and it is catching up in another way. The California legislature passed a couple of bills on the last day of the 2025 legislative session this … [continued]
For years, I’ve been arguing with EV enthusiasts about transmissions. While EV manufacturers can get away with just one gear ratio, the benefits of extra gears are obvious to people familiar with automotive technology. Torque multiplication at low speeds can help with towing, pulling up hills, and just accelerating a … [continued]
ChatGPT generated panoramic image of a pipeline labeled "H2" bursting open and releasing euros and euro cents instead of gas
The molecules for energy industry has been working hard for years to make it seem as if transporting hydrogen by pipeline is going to be cheap and easy, cheaper and easier than moving electrons in fact. I’ve been tracking this set of bad studies and assessing realities for years. Three … [continued]
New direct line ratings technology enables existing transmission lines to deliver more energy — including clean energy — when and where it’s needed.
Two large solar power plants have been approved this week, along with a new plan for more HVDC transmission lines.
Figure 1. Transmission value was relatively high for links that cross between interconnection regions. The three interconnection regions are: the Western Interconnection, including CAISO and much of the Non-Iso West, the Texas Interconnection, including ERCOT, and the Eastern Interconnection including the remaining regions shown. A number of links that cross between different system operators within the same interconnection region also saw relatively high transmission value.
Market Data Shows the Value of Transmission Remained High in Certain Locations Despite Overall Low Wholesale Electricity Prices In 2023 additional electricity transmission would have provided the most value for links that crossed between grid interconnection regions in the United States or crossed between system operator regions within the same … [continued]
How High-Voltage Direct Current Lines Could Better Connect Solar and Wind to the Current Grid Comparing the Routes: HVAC Versus HVDC It is a question on the minds of grid planners throughout the United States: How can we tap into the nation’s best renewable resources at the lowest cost? That … [continued]
