How India's pursuit of green hydrogen could contribute to global environmental cleanup

How India’s push for green hydrogen could help clean up the whole world

 Although hydrogen is the cleanest fuel, almost all of it is bound to other elements like water, hydrocarbons, and so on. The extraction of hydrogen using commercial methods currently pollutes the atmosphere, but "green hydrogen" is set to change that. In addition, India intends to become a global leader in this area by 2030 thanks to the recently approved National Green Hydrogen Mission. Sanjay Dutta discusses what green hydrogen is.

The term "green" hydrogen, or increasingly just "GH2," refers to the hydrogen that is created when water is electrolyzed using electricity generated by solar or wind power projects.

GH2 is regarded as the "fuel of the future" for the reason that its production and consumption leave no carbon footprint. However, making it takes a lot of energy.

What do the color codes on hydrogen mean?

The source is indicated by the color codes. The most prevalent type currently in use is grey hydrogen that is extracted from natural gas. Coal is gasified to produce brown hydrogen. As a byproduct, this process releases greenhouse gases. Greenhouse gases stored in carbon capture and storage facilities are used to produce blue hydrogen.

What are some uses for hydrogen?

Hydrogen is currently only used in big businesses like steel, fertilizers, oil refineries, and bulk chemicals. Blending with CNG and PNG to reduce their emissions will be a major use.

When was the launch of the GH2 mission?

At the third meeting of investors in renewable energy in November 2020, PM Narendra Modi presented the plan for the first time. In her Budget speech on February 1, 2021, Finance Minister Nirmala Sitharaman outlined the road map by announcing the mission. On February 17, 2022, the power ministry informed GH2 and green ammonia policy enablers. On January 4, this year, the Cabinet approved a package of incentives to start the market.

What is the goal of the Hydrogen Mission?

to lessen India's reliance on energy imports and strengthen India's leadership position in climate action and energy transition. By replacing conventional industrial fuel/feedstock, GH2 has the potential to reduce India's energy import bill by Rs 1 lakh crore and eliminate 68 percent of costly gas shipments. By 2030, the government expects India to meet 10% of global GH2 demand.

What is the price of hydrogen?

Hydrogen prices fluctuate based on its source, market conditions, and exchange rates. GH2 currently costs Rs 300 per kilogram. Since the conflict in Ukraine, the most common form of hydrogen, grey hydrogen extracted from natural gas, has cost between Rs 200 and Rs 250 per kilogram on average.

How much of a push does India have to create a GH2 ecosystem?

just shy of $2 billion. The majority of this money will be used to support domestic electrolyser manufacturing capacity of 15 GW (gigawatts) by 2030. The government anticipates that India will have the world's largest capacity of 60 GW by then. The remaining funds will be applied to projects that require strategic intervention.

How many additional nations are supporting GH2?

According to official documents, 25 nations are pursuing the GH2 goal with government support. Germany's support is the highest, at $10. 3 billion, the US with $9 billion, France with $8 billion, and so on. $4 and two billion from the European Union. three billion

Which Indian businesses are making investments in GH2 projects?

Plans for GH2 on a commercial scale have been announced by GAIL and state-run IndianOil. This week, NTPC became the first organization to combine PNG and GH2. CNG and grey hydrogen can be blended in pilots operated by GAIL and IOC. In Assam's Kaziranga National Park, hydrogen buses are operated by Oil India Ltd. Reliance Industries Ltd., Adani Group, and ACME Group are private companies with enormous plans to manufacture electrolysers, GH2 units, and green ammonia units.

What drawbacks does hydrogen have?

Due to its high energy density, hydrogen poses a risk when transported or stored. This necessitates either converting the gas into liquid ammonia for transportation or setting up GH2 plants close to consumption sites and transporting green power from a distance. The overall cost of the project is affected by both options.
