( see Figure 2 ), Kelvion has developed a comparison table ( see Table 1 ). This table contrasts a fogging system ( adiabatic solution ) with Cascade Cooling for a 200-MWe electrolysis capacity train .
Although Cascade Cooling requires more plot space , it offers significant savings in water and energy , thus lowering operational costs . If additional plot space is available , further improvements can be made by adjusting the switching point for Cascade Cooling . This adjustment leverages the efficiency of Groovy tubes to achieve a lower temperature approach between the dry ambient air and the outlet process temperature during the so-called winter period . Table 2 compares the Cascade Cooling solution with the switching point set at 28 ° C in dry ambient air to a configuration with the switching point set at 30 ° C .
Conclusion
Kelvion ’ s Cascade Cooling solution offers a modular and flexible approach to optimising cooling systems for large-scale green hydrogen plants . By taking into account environmental conditions , process temperatures , ambient conditions , available plot space , water scarcity , and energy costs , Kelvion can tailor the optimal cooling solution for each project . Cascade Cooling is designed to support various development phases , ensuring efficient and effective cooling across different stages of a large-scale green hydrogen project , starting from 100 / 200 MW in the initial phase and scaling up to gigawatts . Close collaboration with plant operators early on is key to enabling proper project design and optimisation .
