The Ministry of New and Renewable Energy (MNRE) has issued standards for green ammonia and green methanol under the National Green Hydrogen Mission. These standards define emission limits and outline certification mechanisms for both fuels.
According to these standards, green methanol refers to methanol produced using green hydrogen. In its production process, renewable energy also includes electricity generated from renewable sources that is either stored in an energy storage system or banked with the grid in accordance with applicable regulations.
The total non-biogenic greenhouse gas emissions resulting from green hydrogen production, methanol synthesis, purification, and on-site storage must not exceed 0.44 kg of carbon dioxide equivalent per kg of methanol, calculated as an average over the preceding 12-month period. During the green methanol synthesis process, carbon dioxide can be sourced from biogenic sources, direct air capture, or existing industrial sources. Additionally, the MNRE will specify a detailed methodology for the measurement, reporting, monitoring, onsite verification, and certification of green methanol.
Meanwhile, green ammonia has been defined as ammonia produced using green hydrogen. The total non-biogenic greenhouse gas emissions arising from green hydrogen production, ammonia synthesis, purification, compression, and on-site storage must not exceed 0.38 kg of carbon dioxide equivalent per kg of ammonia, calculated as an average over the previous 12-month period.
