Huatian CCHP Architecture Converts Exhaust Heat into Cooling Capacity and Compute

Cascaded waste heat utilisation lifts total system efficiency above 65 percent and lowers PUE to 1.092

WUXI, China — A simple-cycle gas turbine discharges most of its exhaust heat to atmosphere. For a data centre that is twice wasteful: the heat is lost, and roughly 20 percent of incoming electricity is then spent on mechanical cooling. Huatian’s combined cooling, heating and power architecture cascades that energy into usable output instead.
On the aeroderivative platform the cycle runs as a closed loop:

The chilled water covers site cooling demand with no electric chillers in operation, turning a 25 MW gas turbine into a 100 MW-equivalent data centre energy system. Total system efficiency exceeds 65 percent, PUE falls to 1.092, and the same fuel input supports 15 percent more compute. The design scales modularly in N × 25 MW blocks.
At edge scale the same principle applies more simply: turbine exhaust drives an absorption chiller directly, with no supplementary fuel and no boiler, holding PUE at or below 1.2 and meeting ASHRAE 90.4.
This is a structural advantage of the gas turbine as a prime mover. Diesel generators and battery storage cannot supply waste heat for absorption cooling at all, and solid oxide fuel cells remain cost-prohibitive at this scale. Where islanding conditions are met, turbine and chiller continue operating together after a grid interruption — reducing the risk of servers overheating because cooling stopped rather than power.
