GIZ provides consultancy to its partners through a wide array of methods. Most importantly, GIZ develops and implements solutions together with partners through close cooperation and process advisory. The project "Green Hydrogen Investments" (GH2I), implemented under the Indo-German Bilateral Development Cooperation by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ) and Ministry of New and Renewable Energy India (MNRE), contributes to a sustainable and inclusive energy transition towards climate neutrality by improving the policy, institutional and technical requirements for the use of green hydrogen in India"s hard-to-abate sectors. The goal of this specific tender is to support GIZ and its partners in achieving these goals. Green hydrogen is particularly important for energy-intensive industrial sectors, such as the iron, e-SAF and fertilizer industry among others, which cannot be efficiently and cost-effectively decarbonized with purely electricity-based technologies. The objective of the tender is to provide high-quality advisory services, ad hoc studies and policy and regulatory instrument proposals and designs in the context of gH2 in hard-to-abate sectors in India based on international experience. The contract offers support through studies in the space of green ports, green iron and steel, e-SAF and green public procurement. The assignment provides the project also with ten regulatory and policy instruments: Policy Instruments: - Framework for Green Hydrogen Demand Creation, e.g. covering sector-specific pathways for the gradual substitution of grey hydrogen in refineries and fertilisers, utilizing non-mandatory and phased market-aligned approaches, and aligning green public procurement with India"s broader decarbonisation goals (NDCs) - Infrastructure Planning Framework, e.g. covering strategic cluster formation, pilot design, RACI-based roles, and te
