The EU's Renewable Fuels of Non-Biological Origin (RFNBO) regulations, embedded within the Renewable Energy Directive (RED II) and further amended by RED III, play a crucial role in achieving the EU's decarbonization goals. These rules target sectors challenging to electrify, like aviation and maritime transport, by setting clear standards for renewable fuels. The aim is to reduce reliance on fossil fuels and promote cleaner alternatives, including green ammonia. The Delegated Acts under RED III define conditions for RFNBOs, emphasizing the use of renewable electricity, GHG emission reductions, and supply chain traceability. India's potential in the global green ammonia export market hinges on understanding and complying with these regulations. While the strict production requirements may pose challenges, they ensure the credibility and sustainability of the produced fuels. By meeting the RFNBO criteria, India can position itself as a frontrunner in sustainable energy practices. Under RED III, RFNBOs must satisfy criteria like renewable electricity usage, GHG emission savings of at least 70%, and maintaining supply chain traceability. Additionally, the legislation distinguishes RFNBOs from low carbon fuels, emphasizing the importance of meeting the defined standards. The use of renewable electricity in RFNBO production offers flexibility, allowing for options like grid mix usage. This method enables fuel production to be considered RFNBO based on the percentage of renewable electricity in the public grid. With the EU focusing on green hydrogen as part of its economic strategy, aligning with RFNBO regulations presents opportunities for India to excel in the global green ammonia market and contribute to sustainable energy initiatives.
