Was wondering if heatpumps would be the next step and on the site that is what they exploring net for the cooling side.

In parallel, the project will assess alternative LCT options — such as heat pumps and rooftop wind turbines — to identify ways to further boost SHIELD’s efficiency. As deployment begins, we’ll also explore how the commercial model can evolve to incorporate services like Distribution System Operator (DSO) flexibility and expanded P2P supply arrangements.

If we are looking at this kind of modeling hopefully district systems could be considered as well.
