The Supreme Court’s recent decision to strike down President Donald Trump’s global tariffs is shaking up the climate tech trade. https://www.japantimes.co.jp/environment/2026/02/25/climate-change/trump-tariffs-climate-tech/?utm_medium=Social&utm_source=mastodon #environment #climatechange #batteries #energy #renewables #electricvehicles #wind #solar
Form needs these deals to scale. Hopefully they will get Iron air firmly on the map for LDES.

Japan is set to prohibit the use of power banks on flights after incidents involving the portable batteries have been reported. https://www.japantimes.co.jp/business/2026/02/18/companies/power-banks-aircraft/?utm_medium=Social&utm_source=mastodon #business #companies #batteries #airlines #aviation
One effect of the under-whelming demand for electric vehicles is a growing shift by some battery manufacturers from batteries for vehicles to batteries for energy storage facilities (needed to smooth out fluctuation in renewable energy generation).
Given storage in energy networks is a current concern for renewables' expansion this looks like helpful move, although what its impact on the supply of EVs will be remains to be seen.

If anyone with some CFD/CAD experience was wanting to contribute to our open-source battery project at https://fbrc.dev, this would be a great way - the Forner-Cuenca group at TU/E released some software for modeling porous electrodes in flow batteries, if it could be adapted to our geometry, we could reduce pressure drop/improve flow uniformity, etc. Forum post with relevant links here: https://fbrc.nodebb.com/post/591

Chinese battery company CATL unveils world’s first sodium-ion battery-powered EV with 248-mile range —
"The battery technology, aiming to hit public roads by mid-2026, could significantly reduce fire risks while improving performance in extreme heat and cold."

The #electric #aviation industry has publicly downplayed the challenges associated with certifying large #lithium propulsion #batteries, but it’s been a topic of intense negotiation behind the scenes. That's why a milestone announced this week by Swiss battery maker #H55 is so meaningful: it shows a manufacturer and regulator agreeing on the specific tests required to demonstrate that a large propulsion battery is safe for #flight.

This kind of technology is one of the reasons that sodium-ion is going to scale much faster than the people focused on relative prices of Lithium think. (It is MUCH harder to build passively cooled Li-ion BESS (if its even possible above very small sizes))

🧠✨ Researchers at #Cornell have developed a "MOTE" – a tiny wireless sensor that can record #brain activity while sitting on a grain of salt.
Powered by infrared light rather than bulky #batteries, these microscopic devices are small enough to monitor neural #health for years without irritating sensitive brain tissue.

Batteries & BESS going gangbusters.
Summary of Volta's 2025 Battery report: https://www.ess-news.com/2026/01/26/voltas-2025-battery-report-costs-keep-falling-boosting-bess-across-the-globe/
Online report is here:
https://volta.foundation/battery-report-2025
BESS deployments increased by 104GW / 257GWh, for a global capacity of 267GW / 610GWh, breaking through 100GW barrier for the 1st time. ~40% of the cumulative BESS capacity was installed in 2025.
Turnkey BESS (Includes all battery and electrical assets & management software) costs fell another 31% from 2024 to 2025.
Moving to Merchant PPAs means:
- There is a solid enough market
- lenders see the project as low risk
- business and technical controls are sophisticated enough to engage directly with the market
The increasing use of merchant contracts for BESS and renewables is an important signal about their maturity.

There are many promising LDES solutions reaching production deployment stage ATM. Here is another.
