David RobertsJust encountered a new (to me) term: "carbitrage," the practice of absorbing clean energy with your EV battery when it is plentiful and selling it back to the grid when it is more scarce. Keep thinking ...
David Roberts"The world is on track to produce about 50% more fossil fuels in 2030 than would be consistent with limiting warming to 2°C and 120% more than would be consistent with limiting warming to 1.5°C."
There lacks a consistent and holistic evaluation of co-benefits of different mitigation pathways in studies on Integrated Assessment Models. Here the authors quantify environmental co-benefits and adverse side-effects of a portfolio of alternative...
David Roberts"While all decarbonization pathways yield major environmental co-benefits, we find that the scale of co-benefits as well as profiles of adverse side-effects depend strongly on technology choice." Renewables-heavy decarb produces the most co-benefits.
The long read: South Dakota is known for being the home of Mount Rushmore – and not much else. But thanks to its relish for deregulation, the state is fast becoming the most profitable place for the mega-wealthy to park their billions
David RobertsHydropower is counted as 2/3 of the world's renewable energy, but "a new study reveals that the climate impact of hydropower facilities varies widely throughout the world & over time, w/ some facilities emitting more GHGs than those burning fossil fuels."
The Texas grid has posed a concerning riddle: How does a state with the nation's thinnest margin of backup electricity and the largest installed wind capacity manage to keep power humming in a heat wave?
David RobertsJim Robb is CEO of the North American Electric Reliability Corp. (NERC), which oversees grid security. He once said at a conference, of TX and its low reserves, "there's no way in hell they can keep the lights on." Then he added, "And yet they do."
After a long, hot summer, grid operators want to know "what's in the soup" in Texas. Michael Hogan's answer: an economically sound approach to resource adequacy.
David RobertsERCOT, the TX wholesale power market, has no capacity market & does not enforce mandatory minimum reserves. Consequently, people keep claiming it's going to run into a reliability crisis. This summer they were *sure*. But it keeps not happening.
Making high-temperature industrial heat from sunlight.
David RobertsMy new post: last month I wrote about the vexing dilemma of how to generate high-temperature heat for industrial processes — without CO2 emissions. Now a new startup with a clever twist on an old technology thinks it can do the job with sunlight & mirrors.
