British company RheEnergise is revolutionizing hydroelectric power storage with its unique approach. Unlike traditional methods that require large mountains, RheEnergise’s technology uses small hills, making it applicable to a greater variety of terrain. In this method, using gravity, a high-density liquid called R-19 is pumped up a hill during the day and released at night to generate electricity on demand.
RheEnergise’s proprietary R-19 fluid is environmentally neutral and has a density 2.5 times that of water. Due to its density, RheEnergise requires only 40% of the height difference and 40% smaller tanks compared to traditional systems, significantly reducing material, installation and energy storage costs. In some cases, smaller tanks can even be buried underground.
The exact composition of R-19 liquid remains a closely guarded secret, but what is known is that it is a powder that is mixed with water to create a dense substance. RheEnergise describes this solution as “ultra cheap”. Individual projects using R-19 liquid can supply between 10 and 50 MW of electricity to the grid, depending on demand.
The scalability and efficiency of the RheEnergise technology make it a significant advantage in the field of renewable energy. With over 6,500 potential sites identified in the UK alone, RheEnergise aims to deploy at least 100MW of R-19 powered energy storage by 2030 through its partnership with Mercia Power Response. While other storage methods such as lithium-ion batteries may be better suited for instantaneous power generation, RheEnergise’s focus is on long-term storage and providing reliable baseline energy for longer periods of time.
RheEnergise’s innovative water storage technology is poised to revolutionize the energy industry, offering a cost-effective and environmentally friendly solution for storing and delivering renewable energy on demand.
