Hydrogen can be produced by various process technologies. Firstly, hydrogen can be obtained from natural gas through a steam reforming process or a methane pyrolysis process. Secondly, hydrogen can also be produced by splitting water into hydrogen and oxygen via electrolysis (power-to-gas). Thirdly, hydrogen can be produced via gasification process, by converting solid fuel (coal or woody biomass) to hydrogen. Fourthly, hydrogen can also by produced through anaerobic digestion, converting wet biomass to hydrogen. At present, steam methane reforming is the most common method of producing hydrogen.
Hydrogen can be utilised directly as fuel or, depending on the application, blended with natural gas.
Hydrogen production from RES-based electricity in power-to-gas facilities or from other fuels in combination with CCS contributes to the decarbonisation of the energy system.
Project envisages construction of a 2 km hydrogen pipeline and facilities connecting Green H2 production plant of Società Chimica Bussi (SCB) to SGI high-pressure gas network. This connection will provide:
GRTgaz SA and Creos Deutschland GmbH are collaborating to create a 100% pure hydrogen infrastructure, connecting the Saar (Germany), Lorraine (France) and the Luxembourg border. This 70 km-long infrastructure will be capable of transporting up to 20,000 m³/h (60 MW) of pure hydrogen via retrofitted existing gas pipelines.
Hydrogen from a large-scale electrolysis shall be injected into the gas transmission network of ONTRAS. The energy will be commercially offered to reduce the CO2 footprint of private households. At later stages the hydrogen ratio in the gas supply of a community will be increased with the target of eventually switch to a 100% hydrogen.
Hydrogen is produced by a 35 MW electrolyser, which is directly connected to a wind farm. The pure hydrogen is stored in a nearby salt cavern. The transport between the underground storage and the end users for the hydrogen inside an existing industrial area is provided by a converted natural gas pipeline.
Snam has launched its experiment of introducing a 5% hydrogen and natural gas blend into the Italian gas transmission network. The experiment, the first of its kind in Europe, is being conducted in Contursi Terme, and involves the supply of H2NG (a blend of hydrogen and gas) to two industrial companies in the area: a pasta factory and a mineral water bottling company.
Nuon / Vattenfall, Gasunie New Energy and the Norwegian energy company Equinor are working together on the conversion of the Magnum power station in Eemshaven. It is planned that the first three units of the power plant that are currently still powered by natural gas will be converted to run on hydrogen between 2023-2025. The Magnum power plant will deliver 440 megawatts per unit.
A project promoted by the Regional and National Government and some private companies: Cemex, Enagás, Acciona and Redexis. The 10 MW green hydrogen production plant will be powered by a 16 MW solar plant. The project contemplates the use of green hydrogen in mobility, as well as its injection into the gas grid.
The strategic goal of Get H2 is to combine regions with a high share of renewable energies from wind and solar sources with H2 production on an industrial scale. The focus is on the development of a nationwide H2 infrastructure with the coupling of all sectors.
The aim of the HESTOR research and development project carried out by a scientific and industrial consortium was to investigate the possibility of hydrogen storage in salt caverns, generated from RES, and its further use for energy generation and technological purposes in oil & refinery industry. The Project also considered technical and economic aspects of the use of hydrogen as a fuel in transport. Read more about the other issues addressed in the document using the link below.
FenHYx is a first demonstrator on a European scale to test hydrogen and decarbonised gases in the networks.The FenHYx platform in particular aims to reproduce the features of gas networks and especially those of the gas transmission networks: compression, expansion, measurement, analysis, injection loop, etc. The opening up of this platform to other operators will contribute to the emergence of the hydrogen sector.
