PUMP-HEAT in a nutshell

THE NEED: Gas Turbine (GT) OEMs and energy utilities look for power flexibility

especially for CHP Combined Cycles (CC), constrained by thermal demand, hence providing limited grid services.

THE IDEA: PUMP-HEAT proposes an innovative concept based on the coupling of CCs

with a fast-cycling highly efficient Heat Pump (HP) equipped with Thermal Energy Storage (TES). The integrated system features an advanced control concept for smart scheduling:

• the HP modulates power to cope with the CC reserve market constraints;
• the high temperature heat can be exploited in the district heating network (DHN);
• the low temperature cooling can be used for gas turbine inlet cooling.

The CC integration with a HP and a cold/hot TES brings to a reduction of the Minimum Environmental Load (MEL) and to an increase in power ramp rates, while enabling power augmentation at full load and increasing electrical grid resilience and flexibility. 18/10/2018 - Thessaloniki, Greece 2

PUMP-HEAT concept overview ➢ Heat Pump (HP) as a smart electrical load ➢ HP may allow CC to sell grid services also when the CC is off ➢ HP will impact on the GT inlet air, reducing P_min and augmenting P_max as required ➢ HP can produce useful heat for DHN, displacing auxiliary boilers ➢ HP will also increase the CC average annual efficiency 18/10/2018 - Thessaloniki, Greece 4

Power reduction Impact on Efficiency

• 22%
• 10%

Inlet Heating (without mass exchange)

Rationale: heating the GT intake through the HP will increase the part-load efficiency by 2% perc. points, across the entire off-design curve
