Summary

The main objective of PUMP-HEAT is to develop and demonstrate up to TRL 6 in the relevant environment (a real Combined Cycle Cogenerative plant) an innovative, easily scalable, economically viable and replicable plant layout based on the integration of heat pumps (HP) and thermal energy storage, to un-tap Combined Cycle (CC) potential flexibility through low-CAPEX balance of plant innovations. The new Pump-Heat Combined Cycle (PHCC) will unlock the current situation of low operating-hours or mothballed (=temporarily suspended to operate) CC and Gas Turbine (GT) power plants. In fact, PUMP-HEAT will improve CCs flexibility and global efficiency, in order to strengthen their role in balancing fluctuations of electrical market with a high penetration of renewable sources (RES), while mitigating the effects of cyclic operation and service life expenditure and reducing CO2 and pollutant emissions in these critical operating periods. This is achieved by the integrated PHCC thanks to an increase in part-load efficiency, a reduction of the Minimum Environmental Load (MEL), an increase in power ramp rates, while enabling power augmentation at full load.

Work performed

PUMP-HEAT is a 36 months project. At M18, the project is progressing smoothly, and 26 deliverables have been submitted in the period M1-M18. Furthermore, also all the milestones have been achieved in this period.

All the project goals for the period M1-17 have been successfully achieved except for the definition of the of some details about IREN demosite layout enclosed within some deliverable These deliverables are all related to the IREN demosite and they have collected a delay because of some internal (IREN) delay in the plant layout definition and procurements. D2.2 - Design and specifications of fast cycling warm temperature HP has been submitted in a partial version, and two more deliverables have not been submitted at all D2.3 - Design and specifications of high temperature steam HP and D5.1 - Report on final construction of demosite.

Furthermore, 1 kick off meeting has been organized, also with 1 pre-kick off meeting, 3 physical General Assembly (Bruxelles, Thessaloniki, Alonte) and other 3 online General Assembly.

In M1-18 activities concurring to the achievement of project main objective were:
• Validation site layout: the UNIGE validation site has been defined and the procurement procedures are currently ongoing
• Requirements for demosite HP and heat exchanger are defined: MAYE provided the list of requirements of HP and heat exchangers for demosite is complete and accepted by relevant partners
• Demosite conceptual plant layout: the IREN demosite have been defined in a preliminary way also including P&ID and all the components from different partners also with the control system
• Two-phase expander laboratory prototype tested with refrigerant fluid: UNIGE has developed and produced different prototypes based on Tesla turbomachienry concept
• Requirements for demosite TES are defined: KTH provided all the necessary informations for the definition of the Thermal Energy Storages for the two experimental campaign and for the KTH laboratory activities
• MPC runs with the PHCC dynamic models: UNIGE developed the MPC that will be used in the demosite
• MPC runs with the PHCC dynamic models: UNIGE developed the MPC that will be used in the demosite

Final results

As a “demonstration to market project”, all objectives and impact to be achieved by PUMP-HEAT project are currently partially achieved.
Nevertheless it is worthy to highlight that thanks to a robust dissemination, communication and stakeholders’ engagement campaign, PUMP-HEAT project has been properly promoted among industrial stakeholders and potential demonstrator, also having the opportunity to identify a new potential market sector for large size heat pumps and related energy harvesters.

PUMP-HEAT project successfully participated in many conferences, such as IGTC Brussels, October 2018, GPPS Zurich, January 2018 and 2019, and the forthcoming SUPEHR’19 conference, September 2019, to be originated from the common efforts of three sister projects, namely FLEXTURBINE, TURBO-REFLEX and PUMP-HEAT (leader and promoter).
