The CryoHub project is based on storing renewable energy as a cryogenic liquid, which is then boiled at very low temperatures to generate electricity for on-site use or feeding the power grid during peak demand periods.
Dohmeyer will be responsible for completing the final integration and process design of the demonstrator and then for taking the design from the conceptual phase to an installed and working unit.
Judith Evans, of CryoHub, said, “Having experts like Dohmeyer involved will really catapult the project forward to its next stage of implementing the demonstrator at our chosen Frigologix site in Belgium.”
What is cryogenic Energy storage?
The cryogenic energy storage (CES) is simple and logical:
- During period of low power demand and low energy price, a cryogenic gas is liquefied and stored in a well-insulated vessel (charging period).
- During times of high power consumption and high energy price, the liquefied cryogen is pumped and expanded to drive a generator of power which is restored to the electrical grid (discharging period).
“Refrigerated food warehouses require large cooling capacities to maintain or reduce the temperature of food in a way, which maximise product safety and quality,” CryoHub explained in a statement.
“Stored liquid cryogen is capable of providing part of the refrigerating demand in storage warehouses or food factories, being thereby heated for the purposes of power generation.”
“Furthermore, integrating CES into food storage or processing facilities is a novel and attractive means for fostering the employment of renewable energy sources, revealing also a substantial potential to improve efficiency.”
