Közzétételi metaadat

Europe’s energy system is undergoing profound changes. The EU is planning a decarbonisation path that will see the EU reduce their emissions by up to 95% by 2050. To reach this ambition of a carbon-neutral energy supply, the electricity sector will see an increase in variable renewable energy sources (RES) like wind and solar power in the generation portfolio. As a consequence, the electricity system will not only continue to face varying electricity demand throughout the day, but increasingly experience generation-driven fluctuations. The conversion of excess electricity to hydrogen (and vice versa) can help facilitate the integration of large shares of intermittent renewable sources into the electrical grid. Water electrolysers can produce hydrogen from excess or low-cost electricity, either connected to the grid or in off-grid installations. The conversion of (renewable) electricity to hydrogen, also referred to as power-to-hydrogen (PtH), enables the long-term storage of energy and can reduce the load in electricity grids. The produced hydrogen can either be used directly as a chemical feedstock, as a fuel for transport, be fed into the natural gas grid, or be converted back to electricity during periods of large demands. When hydrogen is injected into the gas grid it will increase the share of renewable energy in the natural gas grid, and from there in the end-use applications of transport, heat and industry, where achieving higher-renewable shares is technologically more difficult and more expensive than for power generation. Moreover, by exploiting the huge storage capacity of the gas system, hydrogen effectively decouples energy supply from demand in time and in location and links the electricity transmission and natural gas grids, thereby enhancing energy security. The main objective of the SFEM/WG Hydrogen was to perform an analysis of the state of the art of technology and standardization and a gap analysis on the main barriers including challenges and needs. A second objective was to establish contact with key stakeholders from gas sector, grids, electric supply, mobility, the Fuel Cells and Hydrogen Joint Undertaking (FCH JU) to perform the work in the most effective way and to have broad support from the stakeholders for identifying the key challenges. Also the link to EC services, DG JRC, DG RTD, DG ENER, DG GROW was seen as important. The final objective is to set a long term collaborative framework (liaison) with major bodies for strengthening cooperation between regulatory work, standardization work and RDI programs (e.g. European Commission, JRC, FCH2 JU, IEA, ISO, IEC). The scope of the working group covered the production of hydrogen through electrolysis and the transportation, distribution and usage of that hydrogen in pure form or as a natural gas dominant mixture (H2NG). In addition, actions in cross-cutting fields such as safety and training of personnel were identified. These activities will help increase the societal acceptance of hydrogen, key to a successful market uptake.
