Application Areas and Advantages of Using Green Hydrogen Technology

The non-renewable resources are depleting fast and are being replaced by renewable energy, and one such clean source among them is hydrogen. Being a by-product of water, hydrogen is extracted through the process of electrolysis. This clean form of energy can be used for powering several operations, including manufacturing and transportation, among others.

Green hydrogen technology is expected to become a mega-billion worth of technology with its applications across industries. Also, taking into consideration the increasing demand for fuel for various activities, several countries have already started formulating initiatives and steps to harness the benefits that green hydrogen technology offers.

The green hydrogen technology is expected to expand rapidly as a result of its improved functionality and distinct properties, which are required in applications such as oil and gas, petrochemical, electric vehicles, and power generation. In the present scenario, the electric vehicles industry is an emerging application area for green hydrogen.

The areas of application of green hydrogen technology are detailed below:

  1. Oil and Gas: Green hydrogen is one of the gases with an increase in demand from the petroleum refining industry due to its function in different refining processes. During these refining processes, hydrocarbon compounds rich in sulfur are hydrogenated to produce hydrogen sulfide and are treated to reduce sulfur dioxide emissions and remove sulfur to prevent catalyst poisoning.
  2. Petrochemical: Green hydrogen is used to produce ammonia in the petrochemical sector, which can power household cleaning and fertilize plants. The conventional manufacturing of ammonia (NH3) is a dirty process. But without ammonia, one would not be able to produce food for nearly 60 percent of the world’s population. Ammonia is made from nitrogen and green hydrogen. The petrochemical industry is one of the largest consumers and producers of green hydrogen.
  3. Electric Vehicles: One of the most promising areas for green hydrogen is the electric vehicle segment. A hydrogen vehicle is an alternative fuel vehicle that uses hydrogen as its primary fuel. Hydrogen vehicles include space rockets, automobiles, and other means of transportation. The size of the hydrogen fuel tank determines the quantity of energy stored onboard.
  4. Power Generation: The world is currently moving toward green energy, and green hydrogen is one of the power industry’s replacements. Green hydrogen has the potential to reduce the carbon footprint of current coal-fired power facilities. Due to the high cost of acquiring green hydrogen, the total cost of green hydrogen-based power will be higher than existing nuclear and petroleum-based electricity.

Benefits of Using Green Hydrogen

  • The supply of hydrogen is limitless as it can be easily produced and transported from an abundantly available renewable source.
  • Hydrogen can be easily stored in large amounts and for a longer duration of time than other batteries.
  • Hydrogen contains almost three times of energy almost equivalent to the energy generated by fossil fuels.
  • Since green hydrogen can be stored easily, it can be used to power households through existing pipelines.
  • Hydrogen fuel cells can power anything that is run on electyricity, as the fuel cells need not to be charged till the time hydrogen gas is present in the battery.
