Green hydrogen: the fuel of the future?

What is green hydrogen? Why is India trying to follow it and how much does it produce?

Stories so far: At the World Economic Forum in Davos, Switzerland, a few days ago, Petroleum and Natural Gas Minister Hardeep Singh Puri said that India would emerge as a green hydrogen leader by capitalizing on the current worldwide energy crisis. His confirmation came nearly a month after Oil India Limited (OIL) commissioned India’s first 99.99% pure green hydrogen plant in Jorhat, eastern Assam.

What is green hydrogen?

Hydrogen is a colorless, odorless, tasteless, non-toxic and flammable gaseous substance, and it is the lightest, simplest and most abundant element in the family of chemical elements in the universe. But the color – green – preceded by it makes hydrogen the “fuel of the future.” The green color depends on how electricity is generated to obtain hydrogen, which does not emit greenhouse gases when burned.

Green hydrogen is produced through electrolysis using renewable energy sources such as solar, wind or hydro power.

India has just started generating green hydrogen with the aim of increasing non-fossil energy capacity to 500 gigawatts by 2030. On April 20, the first pilot plant of 99.99% pure green hydrogen was set up in eastern Assam Duliajan.

Green hydrogen can be stored for long periods of time. Stored hydrogen can be used to produce electricity using fuel cells.

Green hydrogen is produced through electrolysis using renewable energy sources such as solar, wind or hydro power. Hydrogen can be “gray” and “blue” as well. Gray hydrogen is created through fossil fuels such as coal and gas and currently accounts for 95% of all production in South Asia. Blue hydrogen is also produced using electricity generated by burning fossil fuels but using techniques to prevent the carbon released during the process from entering the atmosphere.

Why is India seeking green hydrogen?

Under the Paris Agreement (a legally binding international treaty on climate change aimed at limiting global warming to less than 2°C compared to pre-industrial levels) of 2015, India is committed to reducing greenhouse gas emissions by 33-35% from 2005 levels. At the COP For 2021 in Glasgow, India reiterated its commitment to transition from a fossil- and import-dependent economy to a zero-economy by 2070. The average annual energy import bill in India is more than $100 billion and increased consumption of fossil fuels has made the country a high carbon dioxide emitter. carbon (CO2), which accounts for approximately 7% of the global carbon dioxide burden. In order to become energy independent by 2047, the government stressed the need to introduce green hydrogen as an alternative fuel that could make India a global hub and a major exporter of hydrogen.

The National Hydrogen Mission was launched on August 15, 2021, with the goal of reducing carbon emissions and increasing the use of renewable energy sources.

How much green hydrogen does India produce?

India has just started producing green hydrogen with the goal of increasing non-fossil energy capacity to 500 gigawatts by 2030.

On April 20, 2022, the public sector oil company, headquartered in Doligan district in eastern Assam, set up the first 99.99% pure green hydrogen pilot plant in India, in line with the goal of “making the country ready for pilot production of plants” hydrogen and its uses in Various applications “while” research and development efforts are underway to reduce the cost of producing, storing and transporting hydrogen.

The plant was set up at the pioneer petroleum exploration pioneer’s Jorhat pumping station, also in eastern Assam.

Powered by a 500 kW solar power plant, the green hydrogen unit has the capacity to produce 10 kg of hydrogen per day and expand to 30 kg per day.

A specialized mixer has also been installed to mix the green hydrogen produced from the unit with the natural gas supplied by Assam Gas Corporation Limited and supply the blended gas to the Jorhat area for domestic and industrial use.

Oil has hired experts from the Indian Institute of Technology in Guwahati to assess the impact of the blended gas on the existing facility.

What are the advantages of hydrogen as a fuel?

The intermittent nature of renewable energy, especially wind energy, leads to grid instability. Green hydrogen can be stored for long periods of time. Stored hydrogen can be used to produce electricity using fuel cells. In a fuel cell, the device that converts the energy of a chemical substance into electricity, hydrogen gas reacts with oxygen to produce electricity and water vapor. Thus, hydrogen can act as an energy storage device and contribute to the stability of the network. Experts say that the oxygen, produced as a by-product (8 kg of oxygen is produced for every 1 kg of hydrogen), can also be converted into cash with industrial and medical applications or to enrich the environment. The prospects for hydrogen made many countries pledge investments with Portugal after it unveiled a $7.7 billion national hydrogen strategy in May. Renewable energy developers see green hydrogen as an emerging market and some have targeted the transportation sector, although electric vehicles are beginning to capture the imagination of consumers today.
