Summary
SCORES will combine and optimize the multi-energy generation, storage and consumption of local renewable energy (electricity and heat) and grid supply, bringing new sources of flexibility to the grid, and enabling reliable operation with a positive business case in Europe’s building stock. SCORES optimizes self-consumption of renewable energy and defers investments in the energy grid. SCORES is a gamechanger in the European energy transition towards a zero-energy built environment.
The most recent trends looking at the roadmap to achieve the 2050 European energy and climate sustainability goals for renewable energy, CO2 emissions and energy efficiency indicate that R&D efforts must combine electricity and heat at the global and local levels. For this purpose, a multi-energy approach on energy generation and conversion is required to release the full potential of intermittent renewable energies. As the building sector accounts for 40% of the total European energy consumption and intends to be “near zero energy†in 2050, the share of renewable energy locally generated and self-consumed in the building must be increased. Hybrid storage (i.e. storage of electricity and heat) is indispensable for creating flexibility, allowing to optimize the balance between the supply and consumption profiles of both electricity and heat for the lowest cost.
The main goal of SCORES is to demonstrate in the field the integration, optimization and operation of a building energy system including new compact hybrid storage technologies, that optimizes supply, storage and demand of electricity and heat in residential buildings and that increases self-consumption of local renewable energy in residential buildings at the lowest cost.
Moreover, SCORES is perfectly aligned with the widespread implementation of smart grids and its corresponding technology (as developed in other Horizon 2020 Work Programmes e.g. LCE 1-2016 and NMBP-18-2016).
Work performed
In general the project is well on-track with the preparations for the demo’s in WP7-8 and the technology developments in WP3-6. Moreover, initial economic analyses have been done in WP2.
In work package WP2 - Modelling and evaluation of the system added value and business opportunities activities have taken place in 4 tasks. D2.1 has been submitted with Results of techno-economic modelling. Business model and commercial deployment roadmap and strategy activities have commenced resulting in delivery of D2.3 Market analysis on hybrid storage components.
In WP3 a smart electric storage heaters with PCM (EHP) and a smart air to air heat pumps with PCM (AHPP) are being developed. The PCM for both systems has been selected based on CFD simulations and experimental work. The final solution for the core geometry has been achieved. For the EHP, the 1st prototype has been assembled and performed test have commenced. Finally, a Dymola model was developed by EDF. Further more the DWH system definition, with the definition of PV/T’s, collectors, number of HPs and water tank have been finished. Definition of the integration of the sizing of DHW subsystem with the CLC unit (WP5), considering the Demo site conditions have been finished as well. Currently the installation of the DHW system in Agen is finalized. The commissioning is planned for March. The system test will start operating in April.
In WP4 D4.1 has been delivered in which multiple battery technologies have been screened on various technical and non-technical aspects. Also D4.2 show the specifications and design of the Electrical Storage System (ESS) is described in detail.
A WP5 results is D5.1.This report describes the preliminary design of the CLC storage system with the definition of several concepts of CLC reactor configurations. Additionally, a detailed analysis of legislation related to hydrogen use in building environment was performed. In parallel task T5.2 - Enhancement of the CLC storage subsystem has been running. A prototype of the CLC reactor has been scaled up and is used to optimize its performance. The prototype was integrated into a test rig and an extensive test campaign is taking place. Self-sustained reduction and oxidation were observed.
a result of WP6 is D6.1. In this document the requirements, a preliminary design and a control strategy for the BEMS are presented. The energy reduction will be applied by managing the energy flows and controlling the storage systems, with a target of 30% energy reduction for Demo A&C and 20% for Demo B. As result of the preliminary design based on the requirements, a BEMS system architecture is defined.
WP7 delivered 3 documents. D7.1 presents the characteristics of the demonstration site located in Gleisdorf, Styria in Austria. In D7.2 the master system breakdown is elaborated from level 0 to level 3. In D7.3 the detailed system design is summarized and described.
In WP8 also resulted in 3 documents. D8.1 presents the characteristics of the demonstration site B located in South of France. In D8.2 the master system breakdown is elaborated for the French demo similar to D7.2. D8.3 provides the current status of the design of the SCORES demonstration B in the south of France (DEMO-B).
In WP9 various activities have been planned and performed to boost dissemination and exploitation of the project results of which deliverables D9.1 Project website, D9.2 Communication and Dissemination Plan, D9.3 Data Management Plan and D9.4 Brochure, rollup poster, project presentation design are proof. A Exploitation Workshop has been organized by Fenix at GA2. The findings are reported in D9.5 Initial Exploitation Plan.
Final results
Impact of the Scores system will be a broad assessment covering various economical levels like individual home owners, housing companies, grid owners, energy companies and governments, ecological issues and also the security of supply / reduced European dependence on fossil fuels originating from instable countries from across the globe.
An initial impact assessment has been performed for the two demo cases: Demo A, in Northern European, connected to a district heating and Demo B, in Southern European, without district heating connection. For both cases 30 – 50 % energy gains and ROI periods between 7 – 19 years are predicted, using typical European current day price conditions. Including typical future energy scenarios, i.e. increased CO2 taxing, increased flexibility in energy prices, taxing for grid compensation, projected future financial benefits will increase even further. Since both demo cases can be considered representative for the European dwelling stock, impacts well above the values stated are considered realistic, when SCORES hybrid (storage) technologies are widely introduced on the European market.
The expected impact as it is set out in the work program are: - Demonstration of the economic viability of the overall storage systems with return of investment of less than 20 years and proof of the potential for market penetration
- Technologies which are reliable and operating for a minimum of 30 years - Provide compact systems (volume of storage limited to 1 m3) - Overall net energy gain of minimum 30% - Validated contribution to energy system flexibility
