In order to assess the potential hydrogen release, the proposals should:

• Identify, classify, quantify and prepare an inventory of the types of anthropogenic hydrogen releases expected throughout the hydrogen chain, including production, handling (e.g., compression, liquefaction, packing into hydrogen carriers, purification), transport and distribution, storage, and final uses;
• Identify the most critical elements of the hydrogen chain with regard to potential hydrogen releases considering the different building blocks (e.g., production, handling, etc.);
• Develop and validate appropriate methodologies and test methods and protocols to provide the required data on releases of hydrogen from the most critical elements of the hydrogen value chain. Methods are needed which fulfil similar roles as in the existing natural gas supply chain. These may include methods to enable the identification of sources of hydrogen releases (for example as in leak detection, maintenance and repair programmes), to quantify the mass emission rates of releases into the atmosphere, and to provide test methods to characterise the performance of equipment for hydrogen use. The methods and protocols should be developed considering the potential for future standardisation;
• Identify the total potential hydrogen releases along the whole hydrogen value chain, considering the different building blocks (e.g., production, handling, end-uses, etc.). The proposals should develop simulation tools able to characterise the total potential hydrogen releases considering the different hydrogen scenarios;
• Identify mitigation measures, engineering solutions, technologies, research and development actions to minimise the release of hydrogen.

Research and experimental activities, including the industry contributions, should support the scientific community in the assessment of the quantification of the potential impact of the hydrogen release from the hydrogen value chain on the climate, providing data and tools for the quantification of the total hydrogen released.
