INST uses Fish Gills to develop low cost electro-catalysts

The Institute of Nano Science and Technology operating under Department of Science and Technology has launched an environment friendly catalyst for rechargeable metal battery.

Highlights

The Catalyst used is made of fish gills. It is low cost and can be used in energy conversion devices. The catalyst invented will overcome the bottlenecks in storage technologies such as metal-air battery, fuel cell and biofuel.

The Catalyst can be used as next generation non-precious carbon-based catalyst.

Catalysts in Biofuels

The Catalysts used in biofuel storage technologies are sodium hydroxide, potassium hydroxide and sodium methanoxide. A biofuel cells are those cells that use living organisms to generate electricity. The metal oxides used in these batteries are harmful as they cause permanent damage to tissues

Metal Air Batteries

The Metal air batteries use metals as anode and air as cathode. However, catalysts and electrolytes have hindered the development of metal air batteries.

Fuel Cell

A Fuel Cell converts chemical energy into electrical energy. Usually, platinum, a very expensive metal is used as catalyst.

First indigenous bio-jet fuel powered IAF aircraft lands successfully in Leh

The AN-32 aircraft of Indian Air Force powered with 10% blend of bio-jet fuel took off and landed successfully in Leh airport.

Highlights

This is the first time, bot the engines of an aircraft are powered with bio-jet fuel. Leh is located at an altitude of 10,682 feet above sea level and is one of the highest operational air field. It challenging to fly an aircraft in the region due to wind turbulence and proximity of mountainous terrain.

Fuel Technology

The technology of the fuel was produced by CSIR-IIP in 2013. However, it couldn’t be used for commercial purposes due to lack of aviation test facilities. Indian Air force in 2018, sponsored the project and channelized material resources and human resources to complete fuel testing.

The bio-jet fuel is manufactured from “Tree-Borne oils”. The raw materials for the oil is grown and procured from Chhattisgarh tribal areas. This will help in reducing India’s dependence on crude oil imports and also will assist in reducing carbon emissions.
