ELSA Report Summary

Project ID: 646125
Funded under: H2020-EU.3.3.

Periodic Reporting for period 1 - ELSA (Energy Local Storage Advanced system (ELSA))

Reporting period: 2015-04-01 to 2016-09-30

Summary of the context and overall objectives of the project

Storage is one of the core elements of the forthcoming energy supply system to enable an increasing local production of renewable energy sources (RES) with fluctuating power output. Storage is actually a key enabler to accelerate the Smart Grid transition, as outlined by European climate and energy policy.

ELSA does not only give additional life to electric vehicle batteries before they are recycled, but also creates stationary storage solutions that comply with the high safety standards required for electric vehicle batteries in a cost-effective manner. ELSA proposes scalable, easy-to-deploy energy storage solutions for factories, large offices and residential buildings and districts.

The main objectives of the EU-Project ELSA are:
• To enable an increasing local production of renewable energy and to accelerate the Smart Grid transition.
• To develop a stationary storage system based on second life EV batteries without previous dismantling of the individual battery packs
• To design a low cost industrialised power converter specially designed to work with 2nd life batteries
• To develop an innovative local ICT-based Energy Management System to interface the storage with the building EMS or with the distribution grid
• To include in the development works, communications and services in order to fully exploit the ELSA concept for local energy optimised management of hybrid virtual multi-source storage system and to integrate existing Web/IP based communication standards for Automated Demand Response (ADR)
• To demonstrate the economic viability and effectiveness of innovative storage services and related business models.

The ELSA consortium consists of 10 members from five EU countries: Bouygues Energies & Services, Renault SAS, Nissan West Europe SAS, RWTH Aachen University, United Technologies Research Centre Ireland Limited, Engineering Ingegneria Informatica S.p.A., B.A.U.M. Consult GmbH, ASM Terni S.p.A., Gateshead College and the Allgäuer Überlandwerk.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

During the first half of the project the work performed includes:

Requirement analysis and System Level Specification
Identifying the services offered leveraging on distributed storage for ELSA, these included both potential envisioned services and actual services that could be implemented at the project timeframe conclusion, depending on the regulatory situations. The Use Cases defined during this period describe in detail the specific ELSA functionalities and the set of possible sequences of interactions between ELSA systems and other actors.
A baseline was also defined for ICT infrastructure. Starting from the existing energy management systems the extensions were identified to evolve towards ELSA integrated ICT platform.
A regulatory and normative analysis have been carried out from international standards, to national laws and standards in six European countries of the ELSA consortium (France, Germany, United Kingdom, Italy, Spain and Ireland) to identify and assess potential regulatory barriers and possible normative gaps for preparing future regulatory and normative framework to better promote the development of electricity storage solution, an essential contributor to the low carbon grid.
The flexibility potential of each test site was assessed. It is an off-line assessment, implemented prior to deployment of the ICT platform, to give an indication of the range of flexibilities available at each pilot site.

Design of the storage system:
Starting from the existing architecture, the aim was to define the design for a mass production of the power converter for the ELSA storage System able to implement the different Use Case defined for the project. The different architectures were analysed with potential suppliers to find the most appropriate in term of technical functions and cost. An intermediate architecture was defined for one of the project pilot site to allow testing of the grid services.

Scalable ICT platform for storage and grid services management
A scalable ICT platform for storage and grid services management is being developed. This platform will be ready for installation on the different test sites during the first quarter 2017.
Installation and maintenance of the distributed storage systems:
Installation and commissioning requirements for the storage systems have been studied.
Safety considerations have been studied in collaboration with inspection services, leading to the redaction of a Safety Concept document.
The storage system has been deployed on three pilot sites (Germany, UK and France.

Economic and environmental impact assessment
The market potential of the battery systems in the 5 countries of the project (UK, Spain, Germany, Italy and France) is being investigated. The study aims to discover how a battery system could generate value or bring economies to the end customer in the existing market and regulatory framework of each county. The study covers the domestic and small to medium non-domestic sector.
A first study on the environmental impact of ELSA battery storage systems has been elaborated. The core part of the work is the LCA which is finished for the production of the battery pack including extraction from the vehicle and transport for 2nd life use. The LCA for the remaining system has been started.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

ELSA has been conceived to accelerate the market entry of a major breakthrough in the energy storage industry. Major European industrial players have joined forces with a strong commitment for the manufacture and sale of a storage solution that will be safer, smarter and more affordable than any other existing system.

ELSA impacts in Europe are expected to be significant in terms of lowering energy cost, increasing energy independence and reducing energy environmental footprint. In addition, as the large majority of the planned industrial activities will be based in Europe it is expected that there will be a significant impact in local economies and job creation.

ELSA will strongly impact the current energy market revolutionising the access to storage.
One of the major impact in the market segments will be an acceleration of the large office applications.
A second one will be the integration of storage services in network management, increasing the grid security and stability and reducing grid congestion, particularly exploiting storage with electronic interfaces to facilitate the integration and back-up of highly variable renewable generation and dispersed demand response and providing new grid supporting services (balancing and ancillary services) linked with the availability of storage.

ELSA will accelerate the move towards smart grids, intelligent and green buildings and smart towns.
