One of the interesting things I’ve been doing is participating in a review group for a European study on heavy vehicle decarbonization comparisons and simulations. That means, among other things, that I’m poking at the assumptions being used. As the paper is in review and assumptions are being tested and … [continued]
It’s always interesting to figure out why irrational things occur. In the case of London’s foolish hydrogen buses, apparently Wrightbus going into administration aka bankruptcy proceedings led to well-connected people like Wrightbus owner Jo Bamford’s father, Lord Bamford, the man who inherited British firm JCB and was also knighted for … [continued]
California’s Advanced Clean Fleets Rule faces legal opposition, threatening billions in health and economic benefits. California’s Advanced Clean Fleets (ACF) rule combats toxic freight pollution in the state. Driven by decades of advocacy from frontline communities, the rule accelerates the deployment of zero-emission trucks, yielding an estimated $26.5 billion in … [continued]
A new direct air capture system deploys salty wastewater to transform airborne carbon into solid carbonates and produce fresh water, too.
Two states with rapidly growing wind and solar generating fleets account for the bulk of the capacity additions. California has the most installed battery storage capacity of any state, with 7.3 GW, followed by Texas with 3.2 GW. The rapid growth of variable solar and wind capacity in states such as California … [continued]
In terms of cumulative solar power capacity, California has more than twice as much installed than #2 Texas — 43,244 MW versus 20,028 MW. Florida then comes in at third with 12,877 MW, North Carolina in fourth with 8,648 MW, and Arizona in fifth with 6,731 MW. As you can … [continued]
We recently released a new report that evaluates potential scenarios for electric grid transmission development to support floating offshore wind along the northern coast of California and the southern coast of Oregon. The scenarios include onshore and offshore (undersea) transmission systems, with interconnections ranging from 7.2 to 25.8 gigawatts of generation capacity. … [continued]
Fremont, California-based Amprius technologies is the manufacturer of some of the highest energy density lithium-ion battery cells in the world. This was accomplished using their proprietary silicone nanowire anode technology that enables a step change improvement over the traditionally graphite-based lithium-ion cell chemistries. Higher energy density and volumetric density matters … [continued]
Electrify America recently released a report on progress made in California. In the report, the company updates us on how the charging network is doing, what it plans to do next, and some challenges EA has run into. Why release a report? Well, there’s no nice way to bring up … [continued]
As more solar capacity has come online in California, grid operators at the California Independent System Operator (CAISO) have observed a drop in net load (or the demand remaining after subtracting variable renewable generation) in the middle of the day when solar generation tends to be highest. When graphed for … [continued]
