The National Green Hydrogen Mission (NGHM) has several regulations and standards, including:
Greenhouse gas emissions
For green hydrogen produced through electrolysis or biomass conversion, non-biogenic greenhouse gas emissions must be less than 2 kilograms of carbon dioxide equivalent per kilogram of hydrogen over a 12-month period.
Hydrogen detection apparatus
ISO 26142:2010 sets requirements for hydrogen detection apparatus, such as precision, response time, stability, measuring range, selectivity, and poisoning.
Hydrogen generators
ISO 16110-1:2007 applies to hydrogen generators that convert fuel into a hydrogen-rich stream.
Pressure relief valve (PRV)
The NGHM specifies tests and requirements for the PRV, a component of the compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blend fuel system.
Other regulations and standards for green hydrogen include:
Approvals
Setting up a green hydrogen project requires approvals from the central, state, and local governments.
Certification
The Bureau of Energy Efficiency is the nodal authority for accrediting agencies that monitor, verify, and certify green hydrogen production projects.
Methodology
The Ministry of New and Renewable Energy specifies a methodology for measuring, reporting, monitoring, onsite verification, and certification of green hydrogen.
