EHS guidelines for green hydrogen:

 Here are some EHS guidelines for green hydrogen:

Green hydrogen standard

The Ministry of New and Renewable Energy (MNRE) of India defines green hydrogen as having a greenhouse gas emission threshold of 2 kgCO₂eq/kg H2 over a 12-month period. This threshold applies to both electrolysis-based and biomass-based hydrogen production methods. 

IS 16509:2020

This standard defines safety, construction, and performance requirements for hydrogen generators. It applies to hydrogen generators used for industrial and commercial purposes, as well as for indoor and outdoor residential use. 

General EHS guidelines

These guidelines include understanding the likelihood and magnitude of EHS risks. This includes considering the nature of project activities, such as whether the project involves hazardous materials or processes, or will generate significant quantities of emissions or effluents. 

Safety concerns

Liquid hydrogen can be hazardous and can cause fire, explosion, asphyxiation, and exposure to extremely low temperatures. 

Setting up a green hydrogen project in India requires approvals from the Central Government, State Governments, and local bodies.
