Story summary

Pumped hydro technology, dating to the late 19th century, is gaining renewed attention for storing energy from wind and solar.
In 2025, the United Kingdom wasted over £1 billion by shutting down wind turbines due to low demand.
RheEnergise has developed a denser fluid approach that enables more compact storage, with 6,500 viable sites versus 20–25 for traditional pumped hydro.
