Summary Nuclear hydrogen production via commercially mature water electrolysis technology is a promising, low‐carbon route to bulk quantities of hydrogen for industrial decarbonization. This has special relevance to all energy resource‐poor countries like India who must also reduce dependence on imported fossil fuels and chemical feed stock like natural gas. This study assesses green hydrogen demand in major Indian industries vis‐à‐vis the corresponding hydrogen supply capability via water electrolysis by Indian nuclear power reactors. India's existing, upcoming, and planned nuclear reactors can power modular water electrolysers to produce 1.8–4.0 million metric tons H2 per annum at annualized production costs competitive with current renewable hydrogen costs. Nuclear hydrogen can meet between 6% and 15% of the current green hydrogen demand of priority sectors in India. Project profitability requires sale price of nuclear hydrogen to be at least 60% to 90% above the levelized production cost. Depending on the end user sectors, nuclear hydrogen can enable avoidance of 490–570 million tons CO2 per annum from several industries beyond the electric power sector. Novelty Statement The study analyses the potential of India's existing and upcoming nuclear power reactors to diversify and support the creation of a domestic green hydrogen supply chain for decarbonization of critical and hard‐to‐abate industries. It analyzes sectoral demands for hydrogen, techno‐economic aspects of nuclear hydrogen production using site‐specific data, including comparison with solar hydrogen. It emphasizes the importance of diversifying the energy mix used for large quantities of green hydrogen for sustainable decarbonization of sectors like fertilizers, metallurgy, and long‐distance transport.

Summary Hydrogen production via water splitting using nuclear electricity is one of the most promising, mature and near‐term deployable low carbon routes to establishing the hydrogen economy in nuclear‐equipped nations. Hydrogen has enormous potential to decarbonize multiple industrial sectors, including the hard‐to‐abate industries, which release significant quantities of greenhouse gases every year. Both nuclear and renewables can be used as energy sources for green hydrogen production, but presently, the focus is on renewables, possibly because of the high upfront capital investment for nuclear power projects and the skewed perception of risk and safety issues surrounding nuclear energy. In this work, the rationale for supporting the deployment and growth of the nuclear‐driven hydrogen supply sector is established from the perspective of the power plant owner and the potential off‐take industries that will require large quantities of low carbon hydrogen for decarbonizing some or all of their operations. The status of the technology alternatives, their techno‐commercial features, the enabling mechanisms for project deployment, and the potential barriers along the way are analysed, and key recommendations for near‐term policy action are provided.

“…Hence, commercialization of SOEC is restricted using air electrode system like LSM [33] . In response to these challenges regarding functionalization of the LSM air electrode, formulation of alternate novel single/double perovskite based mixed conducting material (MIEC) like La 1‐x Sr x Co y Fe 1‐y O 3 , (LSCF), Ba 1‐x Sr x Co y Fe 1‐y O 3 (BSCF), Ba 1‐x Co x Fe y Nb 1‐y O 3 (BCFN), Sr 2 Fe 1‐x Mo x O 6 with extended TPB length have been investigated by several group of researchers [28,33,34,35] . The electrochemical active area is enhanced through TPB comprising of pore, MIEC active site and ion conducting sites (promoting oxygen vacancy‐

Hydrogen energy has emerged as the only renewable which is capable of sustaining the prevalent energy crisis in conjunction with other intermittent sources. In this connection, solid oxide cell (SOC) is the most sustainable solid-state devices capable of recycling and reproducing green hydrogen fuel. It is operable in reversible modes viz, fuel cell (FC) and electrolysis cell (EC). SOC is capable of engaging multiple fuels thereby promoting carbon neutral planet. The all-solid design further augments the optimization of cost, efficiency, durability and endurance at higher temperature. Electrodes are therefore, an important component which is responsible for electrocatalytic processing of fuel and oxidant for higher recyclability of cell/stack. The present review article embarks a detailed overview on the past and present status of electrode composition, heterointerface engineering applicable for SOC's. Recent trends in electrode engineering and the possibilities for advancement in SOC is also reviewed with respect to both experimental and computational aspects.
