 Technology Profile

Title:

Sustainable Aviation Fuels (SAF)
Value Proposition:

Air transport is completely dependent upon liquid hydrocarbon fuels. The technical approval (ASTM D7566) of the 50% biofuel / kerosene mix for aviation fuel, in June, 2011 has resulted in a noticeable rapid increase in interest and investment on bio-jet fuel. Also globally, ICAO’s Carbon Offset and Reduction Scheme for International Aviation (CORSIA) commences with a voluntary period (2021-2026) after which it will become mandatory for international aircraft operators to purchase the required offsets for the growth in CO2 emissions above 2020 levels.Green Aviation Bio-Jet Fuels contribute to around 80%reduction in the carbon footprint for the aviation industry and is a potential offset for CO2 emissions for the aviation industry. CSIR-IIP proposes to set-up a unit for bio-jet fuel and renewable diesel.

Process Economics

  • SAF produced by CSIR-IIP only ~1.5X than the conventional ATF
  • Average Opex : ~0.3 $/kg; Feed price and H2 excluded
  • Payback: ~4 Years (Green premium of naphtha and gases not included)
Summary Application:

CSIR-IIP has developed a single-step catalytic process, which is non-infringing, patented, uses a proprietary catalyst and can process wide-range of feedstocks (plant-derived non-edible, waste, low-cost oils) to produce drop-in biofuel for air and road transport purposes. In addition, our technology reduces the cost of production of bio-jet fuel, when compared to the competing 2-step technologies available from US and Europe.
Advantages:

Salient Features of the Technology

  • Single-step catalytic HEFA process
  • High feed flexibility, suitable for multiple feedstocks
  • Composition similar to ATF having cyclic paraffin, paraffins and aromatics of C7 to C15 Carbons
  • CSIR-IIP SAF has potential of higher blending compared to SAF produced from other techniques
  • Patented non-noble metal-based catalyst
  • General usage authorization for the Indian Air Force (Provisional Clearance Certificate issued by CEMILAC subject to OEM concurrence)
  • 1TPD plant installed in Gujarat for green diesel production
  • Demo plant of 9000TPA SAF will be ready by 2027 at MRPL, Mangalore
