SESSTAM Symposium
Stationary Energy Storage System Technology, Application & Market
Wednesday, January 28 and Thursday January 29, 2015

AABC Europe 2015 - SESSTAM Symposium: Stationary Energy Storage System Technology, Application and Market

The need to reduce energy consumption, improve energy efficiency and reduce dependence on fossil fuel is feeding the development of renewable energy and smart grids. Energy-storage systems designed to make the most of high energy-generation periods and provide energy for low periods are key in the transition to renewable energy sources and a more efficient usage of the grid. For these applications, electrochemical energy storage—batteries—competes with mechanical storage and other systems.
The SESSTAM Symposium will address:
  1. market drivers and scope in a combined session with AABTAM (Session 1),
  2. energy storage in centralized (large) utility systems (Session 2),
  3. energy storage for distributed (small) systems (Session 3), and
  4. integration, logistics, and commercial issues, combined with AABTAM (Session 4).

Symposium Chairman:

Andreas Jossen, Professor, Technical University of Munich

Prof Jossen is Full Professor at the TUM (Electrical Engineering and Information Technology) and the Chair for Electrical Energy Storage Systems (EES). In 1999 he founded the Basytec GmbH. From 1994 to 2010, he was Group leader at the Centre for Solar Energy and Hydrogen Research and Head of the group for Battery System Technology. He holds a Ph.D. in Electrical Engineering from the University of Stuttgart.


Session 1 (joint session with AABTAM):

Advanced Battery Market for Automotive and Stationary Applications

The automotive and stationary markets present great opportunities for advanced high-energy batteries. Battery requirements vary between the specific applications, offering opportunities for multiple technologies. This session discussed the development of the xEV market and the stationary utility-related energy-storage systems, and the expanding battery market for both while assessing market drivers, competing technologies, and technological and commercial challenges.


Menahem Anderman

Session Chairman:

Menahem Anderman, President, Advanced Automotive Batteries


President of Advanced Automotive Batteries and founder of Total Battery Consulting, Inc., Dr. Anderman has led the development and commercialization of high-power Ni-Cd batteries, Li-Ion batteries, and ultracapacitors and spent the last ten years conducting assessments of energy-storage technologies for advanced vehicles, publishing Advanced Automotive Battery Industry Reports and chairing the AABC.

Session 2:

Large Energy-Storage Systems for the Grid

Large Lithium-Ion batteries are being evaluated in numerous stationary energy-storage applications in competition with high-temperature (sodium-based) and redox flow batteries to support the energy-storage needs of large utility applications. This session reviewed the technology's commercial progress and the cost-performance prospects of the various storage solutions.


Wolfgang Weydanz

Session Chairman:

Wolfgang Weydanz, Key Expert for Energy Storage, Siemens Corporate Technology, Siemens AG


Dr. Wolfgang Weydanz works in Corporate Technology at SIEMENS AG. For over 20 years he has been active in the field of electrochemical and electrical energy storage with emphasis on lithium ion batteries. He studied Physics in Erlangen, Germany, and Vancouver, Canada, and received his PhD from Ulm University in Germany. His working experience is as developer of one of the first high power lithium-ion systems worldwide (with GAIA Akkumulatorenwerke), setting up and managing R&D departments with several battery companies in the field of lithium-ion, NiMH and zinc air rechargeable systems (Sanyo Component Europe and ReVolt Technology Ltd). He has a strong background with system integration and application of energy storage. He massively widened his application know how and storage expertise to other fields in electrochemical, thermal and mechanical energy storage as well as renewable energy technologies. He is currently “principal key expert” for energy storage at Siemens Corporate Technology. Further he is author of a book on multiple battery technologies and applications published in 2006, a number of scientific publications, and over 50 declarations of invention / patents filed in the field of energy storage and conversion.

Session 3:

Distributed Energy-Storage Systems

Solar energy usage is on the rise worldwide and with it the need for a long-life efficient storage battery. This session reviewed the battery and system technology of the current installations and discussed technology and commercial roadmaps as the market expands.


Michael Danzer

Session Chairman:

Michael Danzer, Leader, Battery System Engineering Group, ZSW


Dr. Michael Danzer studied electrical and energy engineering at Ulm University, Germany, and at Cardiff University, U.K. He received the Dipl.-Ing. and Dr.-Ing. (Ph.D.) degrees both in electrical engineering from Ulm University, in 2003 and 2009, respectively. His doctoral thesis was focused on the dynamics and efficiency of proton exchange membrane fuel cell systems. From 2009 to 2010, he was at A123 Systems, Inc., Boston, MA, USA, as a research scientist and validation engineer, where he worked in the field of battery characterization and fundamentals of battery operation. Since 2011, he is the Deputy Head of the Accumulator Department at the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (ZSW) in Ulm, Germany, where he leads the Battery System Engineering Group. Since 2011, he is also a Principal Investigator of the System Group at the Helmholtz-Institute Ulm for Electrochemical Energy Storage (HIU), Germany.

Session 4 (joint session with AABTAM):

Logistic Aspects of Vehicle Electrification and Large Stationary Storage Systems

While the biggest obstacle to the expansion of vehicle electrification and ESS proliferation clearly relates to the difficulty for battery technologies to compete with fossil fuel, there are notable commercial and logistics issues. In this session, EV, Utility, ESS systems, infrastructure developers and related stakeholders discussed plans to meet the commercial challenges to vehicle electrification and ESS proliferation, including charging technology and infrastructure, grid integration, maintenance, transportation, and recycling.


Roland Matthé

Session Chairman:

Roland Matthé, GM Technical Fellow Global Battery Systems & Manager Electrification Architecture, Adam Opel AG


Mr. Matthé leads the development of the Li-Ion battery system for GM’s upcoming extended-range EV, the Chevrolet Volt. He began his work in the EFLEX concept team in 2006 and moved to the GM Technical Center in Warren in 2007. Up to then he was responsible for system design of advanced fuel cell propulsion systems and batteries.
