Q. What are the key financial and technological interventions under the SIGHT Programme, and how do they address the cost competitiveness of green hydrogen? (15 marks, 250-350 words)

Green hydrogen's chief barrier is cost — production remains costlier than grey hydrogen, largely due to electrolyser capital costs and renewable power tariffs. The Strategic Interventions for Green Hydrogen Transition (SIGHT) Programme, the largest component of the National Green Hydrogen Mission at ₹17,490 crore of the ₹19,744 crore outlay [1], is designed precisely to close this cost gap through demand-side and supply-side incentives.

Key financial interventions - Two distinct incentive mechanisms: one for domestic electrolyser manufacturing, another for green hydrogen production — a PLI-type, outcome-linked structure rather than upfront subsidy [1][3]. - Competitive bidding administered by SECI, which discovers the lowest incentive per unit, preventing over-subsidisation and pushing bidders toward efficiency [2]. - Incentives are tapering over the scheme period, forcing producers to achieve cost reduction through scale rather than permanent support [3]. - Complementary Mission windows — ₹1,466 crore for pilot projects and ₹400 crore for R&D — de-risk first-of-a-kind applications in steel, mobility and shipping [1].

Key technological interventions - Building indigenous electrolyser manufacturing capacity cuts import dependence and reduces the single largest capital cost component [1]. - Incentive design rewards higher stack efficiency and domestic value addition, driving technology upgradation rather than mere assembly. - R&D support targets improved catalysts, storage and derivative conversion, while pilots validate green ammonia and methanol pathways [1].

Impact on cost competitiveness - Assured offtake plus incentive certainty lowers the cost of capital for highly capital-intensive projects. - Scale effects are visible: SIGHT awards have translated into commercial export contracts, such as ACME's long-term green ammonia (405 kTPA) and green methanol (100 kTPA) supply agreements with Japanese firms [2].

SIGHT thus attacks cost from both ends — cheaper equipment and assured demand — converting a nascent technology into a bankable industry. Sustained grid, standards and infrastructure support will be essential to reach the Mission's 5 MMT by 2030 target [4], advancing India's net-zero commitment and SDG-7 on affordable clean energy.
