The State is working with consultants who have experience with decarbonization of district heating and cooling systems and is looking at several technologies to meet targets as well as considering operational changes that can help buildings reduce demand.
Examples are installation of high efficiency boilers, electrification via ground source heat pumps, hydrogen burning boilers (this will eliminate all CO2 emissions), redesigning building heating systems to accept lower entering water temperatures, and reaping the benefits of being a combined heating and cooling system by rejecting heat from the cooling loop into the heating loop during summer when the heating demand is lowest.
