The STORE&GO approach
STORE&GO goes beyond the state of the art of Power-to-Gas, which has been studied in several research projects. The project focuses on the integration of PtG into the daily operation of European energy grids to investigate the maturity level of the technology. Three different demonstration sites offer highly diverse testing grounds for PtG:
- available energy sources (high wind power; PV and hydro; PV and wind power)
- local consumers (low consumption; municipal region; rural area)
- electricity grid type (transmission grid; municipal distribution grid; regional distribution grid)
- gas grid type (long distance transport; municipal distribution grid; regional distribution grid)
- type of CO2 source (biogas; waste water; atmosphere)
- heat integration (veneer mill; district heating; CO2 enrichment)
Moreover, three different innovative methanation processes will be developed and improved from Technology Readiness Level 5 (TRL) close to maturity (TRL 6–7):
- catalytic honeycomb/structured wall methanation reactors
- biological methanation
- modular milli-structured catalytic methanation reactors
These technologies will be demonstrated at a considerable scale between 200 kW and 1 MW in three different demonstration environments for a runtime of about two years. The resulting product – synthetic natural gas (SNG) – will be injected into the existing grid and delivered to customers.
STORE&GO will exploit the projects results to safeguard the technology. In addition to the technical work packages linked to Power-to-Gas processes, STORE&GO will address the cross-cutting topics of Power-to-Gas. STORE&GO will accomplish the demonstration with a thorough economic and logistic/placement analysis. The integration into the existing power grid will be examined and recommendations for the electricity grid management including Power-to-Gas systems will be given. Furthermore, STORE&GO will assess the economic and business aspects and analyse the large-scale storage and market-uptake potential of the STORE&GO technology. This will lead to business models, a Power-to-Gas roadmap for Europe as well as recommendations for policy makers. Another objective is to reduce the barriers in social public acceptance. Linked to this STORE&GO will examine legislative and legal aspects on European, national and local level, which have a deep impact on the installation and operation of future STORE&GO based Power-to-Gas plants.
STORE&GO will pave the way towards a society whose energy supply chain is almost completely decarbonized.
The ambitious goals and targets of STORE&GO will be reached with the strong partnership established in the project. The consortium is built of 27 partners from six European countries having expertise in the energy sector, process engineering, economics, law and social science.
