Periodic Reporting for period 2 - PUMP-HEAT (Performance Untapped Modulation for Power and Heat via Energy Accumulation Technologies)
Okres sprawozdawczy: 2019-03-01 do 2021-12-31
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) concept 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 can 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.
The consortium worked towards the six main objectives (MO) of the project, each covering one step of the value chain:
MO1: Development of an integrated, flexibility oriented Combined Cycle Balance of Plant concept
Achievement:
Reduction of the Minimum Environmental Load (-16.9% (Bottoming Cycle Heat) ÷-18.6% (HP+ TES charging) of a non PHCC MEL).
Increase of the Maximum Power Output (+10.9% (HP) ÷ +14% (TES) of nominal load)
Consumptions and emissions reduction (CO2 for MEL)
Number of yearly start-ups for the same market condition (-4.3 ÷ +1.4%). Increase of the operative hours for balancing and ancillary services market (-0.2 ÷ +7.1%)
Increase of the yearly efficiency in excess of 1.1%, assessed on a variety of combined cycles and climate conditions
MO2: Effective development of the advanced BoP Components
Achievement:
Full experimental charaterisation and cost assessment of TES prototypes at KTH and UNIGE validation sites
Design achieved and Hex implemented at the cold and warm heat pumps. Air conditioning Hex implemented at UNIGE mGT
Two expanders built, mounted and operated, demonstrating feasibility. Performance improvement needed as future development
MO3: Efficient integration via predictive control systems
Achievement:
Thermoeconomic analysis performed and profitability gain assessed
Non-technical barriers between power sector and HP sector faced and resolved at demosite.
Demonstrated in Model-In-the-Loop and Hardware-In-the-Loop configurations
MO4: Validation and demonstration of components and overall PHCC cycle layout
Achievement:
Experimental monitored data demonstrated power augmentation, MEL reduction, power ramp increase, part-load efficiency increase.
MO5: Demonstration of economic viability, safety and environmental sustainability of the novel solutions
Achievement:
Replication studies performed, guidelines issued for retrofit and new applications
MO6: Communication, dissemination and preparation of the future commercial deployment of the new PHCC concept
Achievement:
Many activities performed including the project SUPEHR’19 international conference

The PUMP-HEAT project has followed a continuous development until the completion of all tasks, facing expected issues on innovative device testing as well as unexpected issues such as termination of two beneficiaries, impact of Covid-19 pandemic, very low river water levels at demosite during last summertime. The Steering Committee, composed of all WP leaders under supervision of Coordinator, maintained constant focus on all the on-going activities, rescheduling the following tasks as needed to mitigate risks and impact on project goals, interfacing with Project Officer as requested, in particular regarding the project extension(s).
At the end, all tasks have been completed, all 12 milestones have been achieved, all 51 deliverables have been submitted, most of them as scheduled.
The project underwent a series of amendments, mainly dictated by two partner withdrawal and to the pandemic situation.
Globally speaking the target project results have been achieved satisfactorily, both towards experimental realization at validation sites (UNIGE and KTH) and at demosite (IREN), allowing for effective project dissemination activities and attraction of stakeholder interest, beyond expectations.
The work has been continuously managed by the UNIGE coordinator with financial coordination support from RINA-C, in close cooperation with all WP leaders also thanks to web-meetings/Telcos.
Regarding replication and dissemination activities (WP6), they have been focused on validation and demo sites, promoting them and targeting upscale and replication.
Technical, economic and non-technical (regulatory, health and safety, intellectual property) aspects have been assessed to draft, via WP6 deliverables, a full replication roadmap of PUMP-HEAT cycles and innovations.
Further to this, PUMP-HEAT results have been always accompanied and promoted by a robust dissemination and communication campaign lead by AUTH that, even in pandemic period, brought to excellent results and promotion of project foreground, among them the organization of SUPEHR’19 conference in cooperation with other similar H2020 projects (Savona UNIGE campus, Italy, in 4-6 September 2019), continuous interaction with ETN (European Turbine Network) and with sisters project (also participating to CINEA/H2020 project workshops) that brought to the participation to different promotional webinars in 2020-2021.
