[GWSG] Supercritical CO2 turbines; leaking LNG

[Tilley, Al]

I am enjoying convalescence and intend to put out a new version of the news list. I’ll share stories I think are receiving too little attention but are especially significant. That will mean that the lists will usually be briefer than they have been. It also means that the list will ignore many of the most significant issues and events. For example, I will assume most of us are already watching COP 28, the EV market, and the House’s attacks on the IRA.


1. A supercritical carbon dioxide turbine the size of a refrigerator can generate enough power to supply 10,000 homes with greater efficiency than a standard steam turbine and ten minutes of start-up time. Whatever process which uses heat to drive a turbine now will convert from steam easily; concentrating solar just got much more attractive. A 10MW pilot project is underway in Texas. https://newatlas.com/energy/supercritical-co2-turbines/

2. Bill McKibben reports that leakage from supply ships renders liquified natural gas at least 24% worse than coal. We have no business producing or exporting it. The link to the OilChange International study Planet Wreckers which is McKibben’s source is in the article. https://billmckibben.substack.com/p/exports-exports-exports?utm_source=substack&publication_id=438146&post_id=138351327&utm_medium=email&utm_content=share&utm_campaign=email-share&triggerShare=true&isFreemail=false&r=52gzi
