I. About EASE » Top priorities and Members


• The European Association for Storage of Energy (EASE) is the voice of the energy storage community, actively promoting the use of energy storage in Europe and worldwide.

• EASE actively supports the deployment of energy storage as an indispensable

instrument within the framework of the European energy and climate policy to deliver services to, and improve the flexibility of, the European energy system.

• EASE seeks to build a European platform for sharing and disseminating energy

storage-related information. • EASE supports the transition towards a sustainable, flexible and stable energy

system in Europe.

II. What is Energy Storage? » The concept


• Energy storage devices are “charged” when they absorb energy, either directly

from renewable generation devices or indirectly from the electricity grid.

• They “discharge” when they deliver the stored energy back into the grid.

• Charge and discharge normally require power conversion devices, to

transform electrical energy (AC or DC) into a different form of electrical,

thermal, mechanical or chemical energy.

III. Context » Intermittent energy sources increase the need of flexibility


Ambitious European and national energy policies present opportunities for storage

Energy policies promoted by the EU policy makers design a new context for

European power systems.

The main trends are:

• Consolidation of a decarbonised generation mix

• Development of renewable energy sources (RES)

• Demand Response

• Adaptation of the physical infrastructure (mainly in transmission and

distribution)

• Integration of electricity markets to improve use of the generation and

transmission infrastructure and reduce price volatility both in time and location



Ambitious European and national energy policies present opportunities for storage

All flexibility sources will be needed:

• “Dispatchable” power plants;

• Demand-side response via a smart grid;

• Interconnection with adjacent markets;

• Energy storage.

IV. Energy Storage Technologies: An overview of possible applications » Many new technologies, but what are the applications?


EASE supports all energy storage technologies and believes that storage needs to

be addressed agnostically.



• Some technologies such as pumped hydro storage, compressed air energy

storage, hydrogen and thermal storage are characterised by their ability to store

energy over time (several hours)

• Others, e.g. batteries and flywheels, are characterised by their ability to deliver

power very fast

Storage duration

Several hours to several days or weeks

Several seconds to several minutes

PHS, CAES, H2 and thermal storage

Batteries and flywheels



EASE has identified and described a comprehensive set of energy storage

applications and organised them by segment of the energy system.

V. Development of storage: the stakes » Significant efforts in RD&D


Innovation in storage technologies (performance, cost, materials) is necessary

but demonstration of the technical feasibility of storage solutions is also

crucial. We need this to have the best cost for European Electricity.

RD&D of energy storage is identified in several existing European technology

platforms.

The EU and Member States need to further support R,D&D of energy storage if

this technology should become a success story.

V. Development of storage: the stakes » Significant efforts in RD&D (short term)


In a time frame of 2 years, EASE and EERA recommend the

following RD&D priorities :

• RD&D on storage has to be strong

• Starting small to medium scale European demonstration and pilot programs focusing on grid integration of energy storage technologies

• Activating small scale grid-connected battery experiments at different voltage levels

• Initiating pilot projects for thermal management and industrial waste heat storage

• Encouraging modeling efforts

development roadmap towards 2030

V. Development of storage: the stakes » Open-regulation for storage (short term)


Regulation:

Even if storage seems able to provide services efficiently to the system (validation in progress

in the demonstrators), some regulation barriers or cross-border differences prevent its

development. An homogeneous treatment could help.

Define a fair market design for all services provided by energy storage is

necessary

• More market integration is needed (cf. graph)

• Storage can provide applications

to both regulated and non-regulated part of

the system - market solutions should be preferred

European benchmark on primary frequency regulation

V. Development of storage: the stakes » For the midterm


In a time frame of 2-5 years, EASE and EERA recommend

changes on Regulation/ Market Design aspects:

• Designing of market terms for integrating energy storage in the electricity market

• Initiating heat storage experiments (including underground technology) to obtain practical experience for different storage configurations

• Initiating medium to large scale underground heat storage experiments to obtain practical experience with storage properties in different geological formations

Joint EASE / EERA main recommendations for European Energy storage technology

development roadmap towards 2030

VI. Conclusions


• Energy Storage will provide essential services along the whole energy chain:

• Balancing demand & supply

• Managing Transmission & Distribution grids

• Promoting demand side management

• Contributing to competitive & secure electricity supply

... thereby supporting in numerous aspects the transition towards a secure,

competitive and decarbonised energy system in Europe!

• European RD&D for energy storage is at the heart of the energy system

decarbonisation.

• EASE believes that the NER300, conceived as a catalyst for the demonstration of

innovative renewable energy (RES) technologies on a commercial scale within the

European Union, should look into energy storage as a fundamental instrument for

RES integration.
