The document summarizes several German government-funded demonstration projects on energy storage technologies. It describes four main funding schemes and provides details on several high-profile projects in different storage areas like batteries, power-to-gas, and hydrogen refueling stations. Overall, over 200 million euros have been invested across many projects focused on developing and demonstrating promising storage technologies.

6. Advanced Adiabatic Compressed Air Energy Storage
› ADELE-ING, 2nd phase of development
› DLR, RWE, Züblin, GE Global Research,
research institutes
› Challenging R&D: heat storage under pressure
› Additional R&D demand: compressor, expander
› More than 10 plant configurations with different
degree of being adiabatic under investigation
› Multi-criteria approach
› Early market entry is expected with partly –
adiabatic, decentralised plants
› Focus: daily charge and discharge, service for
distribution grids (not transport grids)

Project Outline „Energiepark Mainz“
› Partners: Stadtwerke Mainz, Siemens, Linde, University Rhein-Main
› PEM-electrolysers with 6 MW peak power (3 x 2 MW)
› Highly dynamic operation possible
› Flexible ionic compressor
› Products: Green Hydrogen, fuel, admixture to natural gas
› Operation started on 2nd July, 2015, since then: 2 trailers per day

9. Efficient Methanation- and Biogas Technology - WOMBAT
› World´s first power-to-gas plant in industrial scale
› 3 alkaline electrolysers by McPhy at 2 MW each
› Partners: Audi, ETOGAS, EWE Vertrieb, ZSW, Fraunhofer IWES
› Focus of the funded project: synergies between electrolysis & methanation
with the production reactor for bio-methane (EWE)
› Heat management: waste heat of PtG-plant is used to disinfect bio waste
and to heat bio-reactor
› Challenge: intermittent operation of PtG-plant faces continuous heat
demand of biogas-production
› Product: CNG for vehicles (Audi)
› Vehicle approach could provide an early economic perspective
