Discuss how India's biofuel policy (SATAT, CBG blending, SAF targets) can reduce oil import dependence. What are the challenges?

India meets the bulk of its crude oil and LNG demand through imports, exposing the economy to price and forex shocks. Biofuels — compressed bio-gas (CBG) and sustainable aviation fuel (SAF) — offer a domestically produced substitute, and policy has moved from voluntary promotion to enforceable blending mandates.

How the policy can cut import dependence

• SATAT (2018) invited entrepreneurs to set up 5,000 CBG plants with an offtake guarantee by oil marketing companies, explicitly to reduce dependence on crude imports while raising farm incomes and rural employment [1].
• The CBG Blending Obligation makes blending mandatory from FY 2025-26 — 1%, rising to 5% by 2028-29 in CNG (Transport) and PNG (Domestic). Its stated aims are LNG import substitution, forex savings, circular economy and net-zero, drawing about ₹37,500 crore and 750 projects [2].
• SAF targets of 1% (2027), 2% (2028) and 5% (2030) for international flights, aligned to CORSIA, substitute imported ATF in a hard-to-abate sector, with lifecycle CO₂ cuts of up to 80% [3].
• Indigenous feedstock with Make-in-India technology converts agricultural residue and waste — otherwise burnt — into fuel, advancing Atmanirbharta [4]; bringing SAF-blended fuel under the ATF Control Order gives regulatory certainty [5].

Challenges

• Execution gap: against 5,000 plants targeted by 2023-24, the Standing Committee (2022) found only 40 operational; of 3,263 letters of intent, just 35 plants were commissioned, many issued "deceptively" to the same promoters, deterring banks [6].
• Viability: Central Financial Assistance was discontinued in April 2021; returns are low, prompting calls for generation-based incentives and carbon-credit monetisation [6].
• Feedstock seasonality: agricultural residue is available only a couple of months yearly, forcing costly storage; municipal waste and press mud are steadier [6].
• Mandate asymmetry: the obligation binds buyers, not producers; evacuation to the gas grid and single-window clearances remain pending [6].

A blending mandate succeeds only when supply-side economics match it. Assured long-term offtake at feedstock-linked prices, restored capital support and grid connectivity can convert these targets into real import substitution — turning India's waste into energy security consistent with SDG 7 and the net-zero 2070 pledge.
