Given India’s climate ambitions, a national transition to green hydrogen (“GH”) appears to be a pressing requirement. In August 2021, India announced the launch of its ‘National Hydrogen Mission’ (“NHM”) to scale up GH production. In February 2022, the Ministry of Power (“MoP”) announced the Green Hydrogen Policy (“GHP”) as the first tranche of instruments to bolster efforts in this direction. Among other elements, the GHP included an understanding that the renewable energy (“RE”) consumed for the production of GH will count towards renewable purchase obligations (“RPO”) of the consuming entity. This January, India’s Union Cabinet approved the National Green Hydrogen Mission (“NGHM”). In February, the Budget confirmed an outlay of almost INR 200 billion for NGHM. While the NGHM aims to develop policies for establishing a viable GH ecosystem, a framework of standards and regulations is expected to be formulated soon.
However, given the government’s accelerated focus on transforming India into a global GH hub, it is unfortunate that the country does not yet have a supporting framework with respect to hydrogen certification. The proposed deployment and uptake of Indian GH will depend on the widespread acceptance of instruments which guarantee its origin. In addition, such a framework can facilitate the trading of hydrogen as a commodity on national and international markets. While national certification processes must align with international markets, tracking systems will be necessary to trace attributes across the value chain, including for the purpose of creating transparency and boosting demand. Furthermore, a robust certification framework can increase investments in RE for the purpose of producing low-carbon hydrogen.
The GH value chain includes production, transportation, storage, and end-use. Each of these activities involves several underlying processes, every one of which requires the use of energy – thus leading to emissions. These emissions can vary depending on the material and technology used. Although color schemes are popular to characterize different types of hydrogen, color-coding by itself fails to provide meaningful details about associated emissions. For instance, even post-production, GH can be involved in significant emissions by the time it reaches an end-use facility, especially if the energy required for constituent processes is not fully supplied through renewable sources.
While RE certificates (“RECs”) help consumers identify the renewable attributes of the energy purchased/used, being able to have the origin credibly certified enables them to make claims about a certain volume of RE generated. For the purpose of GH certification, in addition to RECs, India could draw on tracking templates for other energy products (e.g., biofuels). Further, given that hydrogen is not a primary source of energy (only a carrier), creating a proper link between GH certificates and RECs will be important. Such linkage is additionally necessary to avoid double-counting. Nevertheless, since GH markets are still at a nascent stage, a transitional period could be allowed during which the electrolyzers used to produce GH are enabled to utilize power from existing renewable plants, backed by RECs.
