Hydrostor is a creator of Advanced Compressed Air Energy Storage (A-CAES) - long-duration, emission-free, economical energy storage. Its method is as simple as it is effective: When surplus power is available on the grid, Hydrostor directs it through turbines, transforms it to compressed air and pump it into massive underground caverns. Once in the cavern, it is retained as potential energy. When the grid requires that power back, the storage straightforwardly inverts the process. Adiabatic compression reuses heat for efficiency, while hydrostatic control guarantees stable pressure, decreasing footprint and enabling flexible siting. The company declares delivery of up to 500MW for 8 hours and project lifetime up to 50+ years.

Eavor is developing next-generation geothermal technologies. Unlike traditional geothermal systems (which require either direct access to hot aquifers or hydraulic fracturing), Eavor-Loop extracts heat from hot rock through conduction. Hot rock is found virtually everywhere beneath our feet, meaning Eavor can extract energy from virtually anywhere on the planet. Eavor-Loop is a closed-loop geothermal system drilled deep into the Earth via a series of multi-lateral wells. The system contains and circulates a patented working fluid that transfers heat from the rock. The fluid circulates naturally, without the need for an external pump, thanks to the thermosiphon effect. The heat is then used in commercial heating systems (e.g., greenhouses, district heating) or to generate electricity using conventional heat to power motors.

Ayrton Energy has developed e-LOHC technology - a combination of liquid organic hydrogen carrier (LOHC) and electrochemistry - for the safe storage and transportation of hydrogen. Unlike traditional hydrogen storage in cryogenically cooled high-pressure tanks, e-LOHC stores hydrogen as a liquid at room temperature, allowing it to be transported like diesel fuel using existing fuel infrastructure. e-LOHC uses a carrier oil that readily absorbs and releases hydrogen gas, like hydrogen sponges. Hydrogen molecules chemically bond with the lean carrier fluid through an electrochemical reaction, creating a safe, energy-dense hydrogen storage medium. When needed, hydrogen is released from the carrier fluid and delivered at a purity sufficient for fuel cells.
