This Deliverable has as its goal to identify legal and regulatory challenges for the development of power-to-gas ar the European union (EU) and national level. The focus is on the national legal framework applicable to power-to-gas in Germany, Italy, and Switzerland, the three countries in which the STORE&GO pilot sites are located. Topics which are covered are: legal classification of pwer-to-gas, unbundling of power-to-gas in relation to system operation and gas storage system operation, national authorisation procedures for the STORE&GO pilot plants, legal measures faciliating the injection of synthetic, or substitute, natural gas (SNG) into the gas network, exemptions from network tariffs and other charges, and national support schemes related to the use of SNG.
This Deliverable is part of the work within the STORE&GO project and has as its objective to identify legal and regulatory challenges at the level of the European Union (EU) for the deployment of power-to-gas. Together with Deliverable 7.3,which will assess national legislation applicable to power-to-gasin the countries where the STORE&GO pilot plants are sited (Germany, Switzerland, and Italy), this Deliverable is part of Task 7.3 of the STORE&GO project,which focus is on legal and regulatory barriers.Together, Deliverable 7.2 and 7.3 will provide input for the STORE&GO roadmap,which will be presented near the end of the project in 2020.
To complement the techno-economic evaluation of the Power-to-gas (PtG) technology (private perspective) a broader assessment looking at all the possible impacts on society is also required (social perspective). The assessment of these external effects could lead to a net positive benefit for society that would justify further public funding and support of the technology. For this task, the Social Cost-Benefit Analysis (SCBA) has been chosen given that it takes all possible changes in society welfare into account. This Deliverablefocuses on the environmental component of SCBA and constitutes the link between environmental impact and the monetary valuation needed to weightwith other variables in the SCBA.
In thisreport, the various factors determining the greening of gas across the EU by 2030 have been inventoried, and summarised in four scenarios, that differ in the degree to which markets on the one hand and policies and measures on the other hand create incentives to get to green gases. In the two extreme scenarios, either (in the optimistic scenario) the share of green gas would grow towards 13% to 14% even if the ‘greening’ through CO2 certificates would not be included, or (in the pessimistic scenario) the current share of about 4% would hardly grow (some 4.5%), again excluding the greening through CO2 certificates. Obviously, if the ‘greening’ through CO2 certificates is included in the scenarios, the differences mentioned could grow towards much wider proportions.
This report aims to investigate the role of Power-to-Gas (PtG) in the electrical system, in particular drawing its possible use in the different sectors of the ES (Electricity System). Since one of the partners involved has special expertise in the operation of gas-fired power plants, coupling PtG with such plants was chosen as first application for a deeper investigation. The study includes the technical and legislative aspects involved in the use of Synthetic Natural Gas (SNG) as fuel for gas turbines. An outlook on further applications promising for investigation is provided.
