Central idea

The Indian Institute of Petroleum (IIP) has developed sustainable aviation fuel (SAF) using home-grown technology from cooking oil and oil-bearing plants.
SAF samples have been sent to the United States Federal Aviation Administration Clearinghouse for testing to obtain the ASTM D4054 qualification from ASTM International.

About ASTM certification

ASTM International is an international standards organization that develops and publishes technical standards for a wide range of materials, products, systems, and services.
It was formerly known as the American Society for Testing and Materials and is based in the United States.
The organization has over 30,000 members from more than 140 countries, including scientists, engineers, and industry professionals.
The standards cover industries such as construction, petroleum, medical devices, and consumer products.

Two of ASTM standards related to aviation fuel are ASTM D4054 and ASTM D7566.
ASTM D4054 sets the requirements for qualifying aviation turbine fuels.
ASTM D7566 sets the requirements for certifying fuels for use in commercial aviation.

The Indian Air Force received provisional certification in November 2021 to use SAF on their test flights, subject to case-by-case approval by the aircraft manufacturer concerned.
However, it is yet to be internationally certified for use in commercial airlines in India.

The Mangalore Refinery and Petrochemicals Ltd is setting up the first SAF plant, which is expected to come online by early 2025.
However, two more SAF plants are expected to be set up by other refineries, probably by 2025-26.
The Mangalore Refinery can produce 20 tonnes of SAF per day, meaning about 7,000 tonnes per year.
However, to achieve even a per cent of blending of SAF in India, around 60,000 tonnes per year are required.

Demand for bio-jet fuel must be increased through a national policy, along the lines of the National Biofuel Policy, for it to be commercially scaled and to accelerate production.
A nodal agency to implement this policy should be formed to bring together energy, transportation and agriculture sectors together under one roof.
Mapping the sources of the various feedstock could aid this policy.
