Across 25 assessed power systems, planning, markets and project pipelines are consistently more mature than the delivered portfolios needed to provide dependable flexibility.
Grid flexibility is easy to mistake for a technology market. One jurisdiction announces several gigawatt-hours of batteries, another creates a new ancillary-service product, and a third launches a capacity auction, pumped-hydro program or demand-response target. Those are meaningful signs of activity, but they do not answer the harder question: can … [continued]
Energyminer has something much better than a rendering. Its Energyfish is a small floating hydrokinetic turbine, mostly underwater, anchored in a river current, sending power to shore through a cable and feeding a land-side power box for grid-compliant electricity. It is not a dam, not a conventional run-of-river hydro plant … [continued]
Tidal energy projects can compete on scale and cost with nuclear energy while creating new urban parks, alternative transportation routes and flood control opportunities, too.
In 2019, consumption of renewable energy in the United States grew for the fourth year in a row, reaching a record 11.5 quadrillion British thermal units (Btu), or 11% of total U.S. energy consumption.
The Maid herself has seen some changes over the 160-odd years it’s been in service, but the biggest change so far comes by way of ABB and the New York Power Authority, which have teamed up to deliver two brand-new, all-electric ferry boats to the iconic falls.
NREL says combining floating solar with existing hydroelectric facilities could generate enough electricity to meet up to 40% of the world’s needs.
EWF appears to be positioning itself wisely and carefully in the emerging blockchain-for-energy space. It’s not trying to boil the ocean, it’s aligning itself with the regulated marketplace for electricity and it’s partnering with serious organizations.
Solar and wind power are absolutely predictable when it comes to variable costs. By contrast, coal and gas power are altogether too variable to be reliable.
Los Angeles Water & Power has a plan to build a pumping station 20 miles downstream from Hoover Dam to return some of the water in the lower Colorado River so it can be used to make more electricity. But the devil is in the details.
New research from Arizona State University has raised the issue of climate-proofing the United States’ electricity infrastructure due to possible negative impacts from climate change presently taking place. According to EurekAlert, two Arizona State University engineers contend the electricity generation and distribution infrastructure in the Western United States must be … [continued]
