provides the necessary cooling capacity to lower the outlet process temperature further. This means that the water consumption throughout the year is as low as possible. This cascade cooling system is a smart solution, combining both advantages of a dry and a wet cooling system, thus lowering energy and water consumption and optimizing CAPEX and OPEX. Another advantage is that the cooling water quality can be lower than in the case of an adiabatic system, or even sea water can be used.

Conclusion There are many different possibilities for an ambient air-based cooling system in large green hydrogen electrolyzer plants. There is no best uniform ambient cooling solution available but to achieve the most suitable cooling solution, various factors need to be evaluated per individual project and often case studies are needed to identify the most appropriate one. Kelvion’ s approach is to get involved in the early stages of the project and advise customers on a tailored, holistic solution for the thermal management system of their plant.
