- Scientists develop an energy-efficient strategy to reversibly change "spin orientation" or magnetization direction in magnetite at room temperature. This would let us create high-density spintronic memory devices with large capacity and even neuromorphic devices that mimic biological neural systems. https://www.tus.ac.jp/en/mediarelations/archive/20201117_8877.html 7 comments science
- Krypton and xenon are useful noble gases that we harvest directly from the atmosphere using an energy intensive process that cools air to -300 degrees F. Now, chemists have created a simple, energy-efficient process to separate these gases at room temperature using a special kind of crystal. http://acsh.org/news/2016/08/03/new-energy-efficient-method-to-extract-noble-gases-from-air/ 15 comments science
- Biden administration to transition coal miners to clean energy with $428m in grants. DOE to direct investment into communities hard-hit by fossil plant closures. 14 projects will address five key supply chains – batteries, clean power, energy efficiency, grid components and low-carbon materiala. https://www.rechargenews.com/wind/biden-administration-to-transition-coal-miners-to-clean-energy-with-428m-in-business-grants/2-1-1728339 147 comments energy
- Clean Energy Tax Credits Are Broken—and That’s How Joe Manchin Likes It | “Direct pay” would make more efficient use of public money and speed up renewable energy investment. But Manchin doesn’t want that. https://newrepublic.com/article/166856/joe-manchins-quest-keep-clean-energy-tax-credits-broken 11 comments environment
- Shipping Liquid Hydrogen Would Be At Least 5 Times As Expensive As LNG Per Unit Of Energy. Delivering the same energy in the form of electricity through high-voltage direct current cables is vastly more efficient. https://cleantechnica.com/2021/12/20/shipping-liquid-hydrogen-would-be-at-least-5-times-as-expensive-as-lng-per-unit-of-energy/ 170 comments energy

- Researchers discover a breakthrough process for directly converting methane to methanol. The new process could lead to production of methanol or acetic acid through more energy efficient, low-cost, and environmentally-friendly ways. http://now.tufts.edu/news-releases/researchers-discover-breakthrough-process-directly-converting-methane-methanol 4 comments science
- Hydrogen Reality Check: We Need Hydrogen — But Not for Everything. In theory, hydrogen can indeed be used to decarbonize almost every sector. But just because it can, doesn’t mean it should. Hydrogen should be prioritized in uses where energy efficiency and direct electrification are not possible. https://cleantechnica.com/2022/07/03/hydrogen-reality-check-we-need-hydrogen-but-not-for-everything/amp/ 16 comments energy
