Full Power — as designed!
We are utterly thrilled to announce that our first ever High-Density Hydro® project in Devon is now producing full power, at the predicted output and on a consistent basis.
Everyone on the RheEnergise team is delighted that the system has reached full power and is performing exactly as designed. This means that we have proven and critically de-risked our High-Density Hydro technology which will allow us to focus on deploying the solution in commercial-scale Long Duration Energy Storage (LDES) schemes in the UK and worldwide.
Our commercial pipeline is $1.75bn for the top 35 deals across multiple jurisdictions, all of which are facing huge demand growth and system reliability challenges.
Reaching full power is undoubtedly a major milestone in our growth ambitions. Our product fits the market need. A solution designed for the part of the market where traded energy volumes are the greatest.
We are tracking 160 deals across 30 countries.
We need to grow our teams to ensure we can haul in these opportunities.
We have launched a fundraising round on Crowdcube.
This fundraising round is a direct investment opportunity via an Advance Subscription Agreement (ASA), which offers a 20% discount on our future Series A institutional round, due to take place later this year.

Our Market Opportunity
RheEnergise’s High-Density Hydro® solution is low cost, globally applicable and with more than enough site opportunities to solve the climate emergency and energy demand growth challenges many times over. Our solution can address a notable percentage of the projected market:
McKinsey say the long-duration energy storage (LDES) market is going to be
$4 trillion by 2040, while the investment bank
UBS say a
34x market growth is needed.
The LDES Council state that the market must scale 50x faster and Bloomberg New Energy Finance show exponential growth as likely.
Few markets are measured in trillions of dollars. RheEnergise’s solution delivers best-in-class economics, a solution for grid stability, industrial electrification, data centres and island grids.
