More than 30 ac c redited certication entities available Book and claim approach used Hydrogen from electrolysis and bio-based allowed


Use 50% of hydrogen for RFNBO (Renewable Fuel of Non Biological Origin) by 2030 RFNBO must be at least 2.6% by 2030 (may increase to 5.7%) RED III not ratied yet – now in trialogue

RED (Renewable Energy Directive) regulatory framework, latest RED II in 2018 RED III included elements on hydrogen and derived fuels

China Governed by China Hydrogen Alliance’s Standard – released 2021 Denes low - carbon hydrogen as 14.51 kgCO/kgH and renewable hydrogen as 4.9 kgCO/kgH

Annual certication and thi rd parties provide on-site audits No chain of custody methodology is dened


ISCC (International Sustainability and Carbon Certication) Plus is a voluntary market -b ased scheme for bio - based recycled material

Scheme can be used to certify renewable hydrogen for biofuels, recycled carbon fuels , and RFNBOs Other entities oversee audits and ISCC issues certicates

additionality is that the power for electrolysis of water to hydrogen should come from new renewable sources rather than taking existing renewable power away from existing electricity users. Hence, the hydrogen will have to be generated by direct physical connection with the power source or through confirmed purchased power agreements, as well as being generated from new renewable facilities and sources. • Temporal correlation : A specification of the time between power generation and use by the electrolysers to generate hydrogen. Most of these

time frames involve calendar hours and do allow for power storage for use by the asset. However, the time frame is purposely condensed to ensure the use of renewable power directly for low- carbon hydrogen. • Geographic correlation : The electricity generation assets and electrolysis system must be within the same geographical region, often defined by bid zones within a given country or groups of countries. • GHG savings : the GHG savings must be accounted for and included to demonstrate that
