CeNS: Low cost Catalyst for Hydrogen Generation

The scientists and researchers at the Centre for Nano and Soft Matter Sciences operating under Department of Science and Technology have invented a low cost effective way to generate hydrogen from water using Molybdenum dioxide.

Key Findings of the Study

The study says that Molybdenum dioxide can act as efficient catalyst to reduce energy used in splitting water into hydrogen and oxygen. The process is called electrolysis.

About Molybdenum Dioxide

Molybdenum Dioxide has the potential to replace the catalyst that is being used currently, that is, Platinum. Platinum is highly expensive and also is available as limited resource on the earth.

About the Study

The researchers grew Molybdenum Dioxide on tin oxide substrates.

Significance

The splitting of water is important to obtain hydrogen. Hydrogen is lately becoming a popular clean fuel. Hydrogen is predominantly used to make fuel cells. In a fuel cell, the chemical energy, that is hydrogen is converted into electricity.

Hydrogen Energy in India

The Ministry of Renewable Energy is supporting Research and Development on Hydrogen Energy and Fuel greatly. The projects of hydrogen transportation is being conducted by Mahindra and Mahindra, Banaras Hindu University and IIT Delhi currently.

Hydrogen Fuel Bus and car launched by NTPC

The National Thermal Power Corporation recently launched ten Hydrogen Fuel Cell based buses and 10 similar electric cars.

Highlights

The buses and cars were launched in New Delhi and Leh. Similar proposal is under implementation in Andaman and Nicobar Islands.

Other initiatives of NTPC

NTPC has been taking several such initiatives to provide e-mobility solution for public transport. This includes providing charging infrastructure and electric bus to state and city transport systems.

NTPC has so far commissioned 90 public charging stations in and around the city of Faridabad.

Why electric buses?

The initiative undertaken by NTPC to procure hydrogen fueled buses is to decarbonize transport system in the country.

Hydrogen Fuel Cell

The Hydrogen Fuel Cell use chemical process to convert hydrogen rich fuel into electricity. The main advantage of fuel cells is that they need not be charged frequently. They produce electricity as long as the fuel is available

In a Hydrogen Fuel cell, the hydrogen is passed through the anode, oxygen is passed through cathode. At anode, the hydrogen molecules are split into protons and electrons. The protons hence formed pass through electrolyte membrane. This forces electron to pass into the circuit, generating electric current.

Benefits

The major benefits of hydrogen fuel cells include high efficiency, low to zero emissions, fuel flexibility, quiet operation, durability and energy security.
