100 MWh Sand Thermal Storage by @polarnightenergy.bsky.social for about 10€/kWh. Despite recent cost reduction in grid-scale batteries, they are still around 200-300€/kWh
=> Using a resistive heater, such sector coupling allows storing excess energy at much lower cost

World's first commercial sand battery begins energy storage in Finland
Wind and solar power are intermittent, generating power when it's available rather than when it's needed, so the green energy transition will require huge amounts of energy storage. This could end up ...

Renewables weren’t to blame for the 2025 Iberian blackout — and history repeats itself.
They’re often the scapegoat:
- 2016 South Australia: blackout blamed on wind, but storms hit the power lines
- 2021 Texas blackout: frozen turbines blamed, but gas supply failed
(Article: Le Soir, May 10 2025)

Complete blackout in Spain, Portugal, and apparently a part of France!
I have been blocked in a train for the last half an hour without any information

Fully agree. And that is one of the main purposes of the Openmod initiative: openmod-initiative.org

Case in point:
Just out: Solar power additions in China in 2024 exceeded expectations, again, with a whopping 277 GW installed in just one year! This was up 28% on the already towering 217 GW added in 2023.
Wind power made a new record as well, with 79 GW added to the grid, up 5% on year.

Where is hydrogen needed most for EU decarbonization?
In this paper, we prioritize hydrogen end-uses at various increasing emission reduction targets:
-50%:Ammonia production
-75% Long-range freight
-90% chemical industry and steel production
Net zero: synthetic fuels (e.g. for aviation)

What comes to mind when thinking about the energy transition?
🌞 For most, it’s about renewables
♻️ Some think about energy efficiency
❗ But almost no one considers reducing demands
In our latest Nature Communication, we explore #EnergySufficiency to reach climate goals!
