Indian Oil Corporation (IOCL) is set to temporarily halt its 3,00,000 barrels-per-day diesel desulphuriser unit at the Panipat refinery to upgrade it for the production of sustainable aviation fuel (SAF) from used cooking oil (UCO). The upgrade, slated for late 2025 or early 2026, aims to produce 30,000 metric tons per year of SAF, supporting India's target of blending 2% SAF by 2028. Despite the unit shutdown, diesel output will continue unaffected due to backup hydrotreaters onsite. IOCL is also exploring retrofitting kerosene-producing units in its refineries to enhance SAF output and will soon open bids for a 70,000 tonne-per-year green hydrogen plant and a new SAF project. Furthermore, the corporation has contracted Larsen & Toubro (L&T) to construct a 10,000 tonne-per-year green hydrogen facility at Panipat, with L&T supplying green hydrogen at Rs 397 per kg. These initiatives are in line with India's strategy to fulfill 50% of its hydrogen demand using green hydrogen by 2030, showcasing a proactive approach towards sustainable energy production.
