While rapid electrification of the economy is going to be an important step towards decarbonising energy systems and enhancing efficiency levels, electricity cannot address certain carbon-intensive sectors which have to be decarbonised to ensure net-zero emissions, said Amitabh Kant, CEO, Niti Aayog. “Hydrogen, as an energy carrier, is crucial for achieving decarbonisation of hard-to-abate sectors. Many sectors such as iron ore and steel, fertilisers, refining, methanol and maritime shipping emit major amounts of CO2, and carbon-free hydrogen will play a critical role in enabling deep decarbonisation,” he said in an opinion column. Saying that India is one of the early movers in the green hydrogen space, Kant listed out the multiple reasons India is pursuing it with “vigour and conviction”. “Firstly, neither hydrogen nor electrolyser is a new technology. More than 70 million tonnes of hydrogen is produced annually across the world, with India clocking around 8 per cent of global production.” “Secondly, India’s distinct advantage in low-cost renewable-energy generation and world-class clean-power execution capabilities makes green hydrogen the most competitive form of hydrogen in the medium run. This enables India to be potentially one of the most competitive producers of green hydrogen in the world. Since 75 per cent of the cost of green hydrogen is dependent on renewable energy, we should target to further bring down the cost of solar power to Re1 per Kw/h through lower cost of financing.” He cited energy security as the third important reason to pursue green hydrogen as “it will enable the emergence of a domestically produced energy carrier that can reduce the dependence on fossil fuel imports of $160 billion per year. “In addition, with 500 GW renewables expected to come on line by 2030, green hydrogen could act as a solution to extract value out of excess renewable power and avoid the duck curve possibilities in the grid. Key policy measures for creating a green hydrogen ecosystem have recently been announced,” he said.
