BATSTORM – A European R&D strategy for battery based energy storage
The BATSTORM project will support the European Commission and the ETIP team in their progress to
identify and support RTD&D needs and market uptake of battery based energy storage as one lowcarbon technology of the future energy system. This objective shall be met in line with the aims to
increase active consumer participation in the energy system and to improve industrial capacity in
Europe. To meet this objective, the knowledge on battery based storages must be fostered and
exchanged between stakeholders and research in the field as well as demonstration projects need to
be collected and efficiently supported. This includes in particular:
2
-
Strategy development
-
Knowledge sharing
-
Support of the policy design process
-
Industrial capacity increase and cost reductions of batteries
-
Connect and involve (especially via http://www.batstorm-project.eu)
Objectives and agenda of the meeting
A BATSTORM expert meeting was held on April 21st 2016 in Brussels with the purpose to:
-
Introduce the first main project deliverable: the draft Implementation Plan 2016-2018
and invite comments and suggestions.
-
Collect any other views and input on the battery-based energy storage in Europe
that could contribute to decision-making on policies and RTD funding.
-
Start a process of periodic interaction with a committed panel of experts
with the aim to collect constructive feedback on the project team’s analysis,
leading to validated project deliverables.

Introduction and remarks by the European Commission
At the beginning of the meeting Henrik Dam welcomed attendant partners and stakeholders of
BATSTORM. He then stressed that energy is one of the Commission’s main subject with the objective
to move the EU towards a low-carbon economy while creating jobs and enhancing competitiveness.
Figure 1: Henrik Dam (European Commission) and project director Frank Wiersma (Ecofys)
He also announced that by the end of April 2016 an issue paper on stationary storage for the
electricity system will be published. It includes following targets that will lead to highly competitive
costs per cycle for battery systems in 2030.
-
costs of less than €150/kWh capacity
-
efficiency above 90 %
-
battery cycle life of several 1,000s
The issue paper should be used as framework for the BATSTORM project. Hence, future system costs
may be assumed rather than today’s prices on the market. Along with this, the Commission would
like to ask the consortium and stakeholders to assume that an proper regulatory framework will
be in place and to further focus technical challenges rather than political challenges as the political
direction is quite clear. Technical and market barriers will be straightened out and a playground for
technologies that provide flexibility will be created.

Key points of discussion on the draft implantation plan
The implementation plan has been compiled under the leadership of Bart Mantels (VITO). He
presented the project team’s approach, the plan’s structure and its content. The investigated pilot
projects as well as the proposed R&I topics were discussed lively with the stakeholder group.
Frank Wiersma collected main points made by the stakeholders on a flip chart and in the end
recapped the session.

made by stakeholders
The implementation plan’s structure follows a matrix posing challenges (technical, market-related,
regulatory, public acceptance-related) over applications (grid, generation, non-residential users,
residential users). Figure 4 displays the results of previous stakeholder feedback and investigation of
research efforts in these clusters.

Topic
Description of remark / discussion
Technical challenges
Energy density
to be increased
Discharge and energy
retention times
to be extended
2nd generation to be
considered separately
Capable communication
infrastructure needed
-
Energy density will be of great interest in order to integrate battery based
energy storage into an urban environment.
-
Battery systems that are tested today in rather rural areas are unimaginable
in urban secondary substations.
-
Longer periods, i.e. longer discharge and retention times, will be needed in
the future.
-
Future battery technologies may close a gap between today’s battery
systems (short periods) and pump hydro storage (large periods).
-
A second generation of battery based energy storage technologies with much
improved performance available should be included and set apart from
current technologies in the BATSTORM project.
-
Current generation: onward development and optimization to be focused
-
Future generation: fundamental work and investments to be done, also aside
from Li-Ion
-
In order to technically enable sufficiently fast communication to control
flexibility and batteries, a proper infrastructure is needed.
-
Smart metering infrastructure is not adequate for this purpose.
-
The participants are aware of technical problems that can arise in the phase
of BES integration (with grid or generation).
-
Participants recommended to discuss with project planners, utilities.
-
A further explanation of safety risks posed by batteries, also regarding
existing elements in the energy systems such as transformers, is needed.
Integration problems
Safety risks to be
explained
Market challenges
Cost per cycle
to be reduced
Business case for
batteries missing
POWNL16059 Benjamin Munzel
- In regard to system prices that need to decrease in the future, not only
material prices play an important role but also the potential number of cycles
a battery is able to perform as the essential indicator comes down to cost per
cycle.
-
The economic issues and cost inefficiencies experienced by many of the
presented battery storage pilot projects are not surprising.
-
Batteries are not made for these kinds of markets.
-
Today, the grid does not yet need batteries (except few cases).
-
There is clearly a surplus of sellers and a lack of buyers.

Topic
System operators
already realize (pilot)
projects
Need for batteries will
arise
EU supply chain to be
strengthened
Procurement standards
Description of remark / discussion
-
There are various examples of DSOs already applying battery storage
systems.
-
However, projects are mostly limited to pilot status and viable only in very
rare cases.
-
Yet, there are grid tasks to which batteries already today offer a costeffective and technically feasible solution.
-
Fast-charging stations for electric vehicles or for a Norwegian electric ferry
that integrate battery storage in order to reduce peaks in the grid and avoid
grid expansion are good examples.
-
The need for batteries will arise in upcoming years and decades when the
demand for balancing storage will exceed seconds or minutes towards hours
and days.
-
With less fossil fuel based generation in the grid it will need another source
of flexibility and balancing.
-
The grid and system operators will sooner or later show value for storage.
-
99 % of all batteries are produced in Asia.
-
The development of a supply chain for battery (system) production in the EU
is desirable.
-
Yet, the EU supply chain does host raw materials producers and battery
system integrators.
-
The supply chain needs to be broken down and analysed part-wise
considering various elements of the supply chain.
-
Considering economic value and opportunities as well as job potential for the
EU may pose many opportunities.
-
There is no (standardized) definition of terms for the procurement process
-
More experience and standardization could reduce costs of whole process
-
Most attendees could not comment on this issue however recommended to
discuss this issue with project planners
Regulatory challenges
Shorten auctioning
times
Proper regulatory
framework necessary
POWNL16059 Benjamin Munzel
-
Shortening auctioning times in energy markets can enable flexibility options.
-
Batteries may participate in multiple applications and markets.
-
A regulatory framework should enable players and make sure the market
does not show value for batteries too late.
-
The ground to commercialise batteries and bring them into the market needs
to be prepared by regulators.
-
Roles in the electricity market need to be defined clearly, i.e. ownership,
ability to manage functionality, market participation etc.
-
Buyers and sellers need to be enabled, same applies for multi-role
applications and business cases.
-
An important step to enable demand for flexibility at distribution grid level,
hence creating a market for flexibility, would be made by enabling
contracting in flexibility services by DSOs, as is common among TSOs.
-
The European Commission recommends focussing rather technical challenges
than political challenges and assures that a proper regulatory framework will
be in place.

Conclusion and next steps
Most importantly, this meeting provided input regarding the preferred direction of the BATSTORM
project. It became clear that regulatory challenges should be considered less while a proper
framework can be assumed. Overall the project’s scope and view shall be focused on future facts and
externalities rather than current market situations and technologies. Therefore, desirable states of
battery technologies and a potential EU value chain will be worked towards to particularly.
This report and the draft version of the implementation plan 2016-2018 will be uploaded to
http://www.batstorm-project.eu/downloads leaving stakeholders the opportunity und deliver further
feedback.
A next expert meeting with a group of stakeholders will be scheduled for after the summer. The
consortium aims to extend the stakeholder group to further players along the whole value chain, i.e.
representatives of manufacturers, academia etc.
