RheEnergise - High-Density Hydro
@rheenergise.bsky.social
RheEnergise is bringing fresh innovation to the world’s dominant form of storage: pumped hydro storage. We call our solution High-Density Hydro®.
Great to see the @FT highlight #PSH for a 100% #renewable grid!
Traditional pumped hydro is limited by location, but @RheEnergise unlocks 100s of 1000s of new sites by drastically reducing the needed elevation.
Thanks to Stephanie Findlay for featuring us!

Can energy infrastructure coexist with nature? We believe it can. 🌱
Our first HD Hydro® project is almost entirely underground, enabling landscape restoration after construction. With rapid planning approvals, we're showing clean energy and environmental stewardship can go hand in hand. #CleanEnergy

#DataCentre power demand is surging. Our modelling shows that pairing HD Hydro® with solar can deliver:
$1.27bn (58%) lower lifecycle costs
Grid reliance reduced to 43%
3.3m tonnes of CO₂ avoided
As data centres grow, #LDES will be essential for reliable, cost-effective power. #RenewableEnergy

The UK is on track for an oversupply of short-duration storage, but a shortage of #LDES.
As Pete Roche notes: “The technology is developing so fast around the globe that the UK’s slow decision-making process means we could miss out on an incredible opportunity.”
