Green hydrogen is a type of hydrogen fuel Produced from Renewable energy sources such as wind, solar, and Hydropower, Green Hydrogen is Regarded as a crucial element in the shift towards a Low-carbon economy as a type of Hydrogen fuel.
It offers a way to Recarbonize sectors such as heavy industry and Transportation that are difficult to Electrify using Renewable electricity alone.
The production of green Hydrogen Involves using an Electrolyzer to split water Molecules into their Constituent parts, Hydrogen and oxygen. The Hydrogen produced can then be used as a clean fuel for Transportation, power generation, and other applications.
It has the potential to play a significant role in Reducing Greenhouse gas Emissions and Mitigating climate change. However, its Widespread Adoption still needs challenges, such as high production costs and more Infrastructure for storage and distribution.
Despite these challenges, many countries and companies invest in Developing green Hydrogen technology as a crucial part of their climate Strategies.
Types of Green Hydrogen:
Several types of Hydrogen are Classified based on the production method and purity level. These types include:
Grey Hydrogen:
This is the most common type of Hydrogen produced from fossil fuels such as natural gas through steam methane Reforming. Grey Hydrogen is the Cheapest form of Hydrogen but emits large amounts of carbon dioxide during production, Significantly Contributing to Greenhouse gas Emissions.
Blue Hydrogen:
Both blue and grey Hydrogen use steam methane Reforming for production. However, blue Hydrogen differs by Incorporating carbon capture and storage (CCS) to capture and store carbon dioxide Emissions underground, serving as an interim measure to reduce Emissions from grey Hydrogen production.
However, it still relies on fossil fuels and does not result in a net carbon Reduction.
Green Hydrogen:
To produce this type of Hydrogen, one uses Electrolysis, which Utilizes Renewable energy sources such as wind, solar, or Hydropower. Green Hydrogen earns high regard as the most Environmentally friendly Hydrogen form due to its lack of carbon dioxide Emissions during production and its potential to greatly reduce Greenhouse gas Emissions.
Production of Green Hydrogen:
The production of green Hydrogen Involves using an Electrolyzer to split water Molecules into Hydrogen and oxygen. The process requires electricity from Renewable energy sources such as wind Turbines or solar panels.
There are several different types of Electrolyzers used for it production. The most common type is a proton exchange Membrane (PEM) Electrolyzer, which uses a solid polymer Electrolyte to transport protons between the anode and cathode. Other types include Alkaline Electrolyzers and solid oxide Electrolyser.
In a PEM Electrolyzer, water is fed into the anode side of the cell, where it is split into Positively charged Hydrogen ions (protons) and Negatively charged oxygen ions (Hydroxide ions). The Hydrogen ions pass through the Membrane to the cathode side of the cell, where they combine with Electrons from the External circuit to form Hydrogen gas. At the same time, the oxygen ions react with water and Electrons from the outer course to form oxygen gas.
Once the Hydrogen gas is produced, it can be Compressed and stored for later use as fuel for Transportation, power generation, and other applications. Hydrogen storage is a critical issue, as Hydrogen gas is highly Flammable and requires Specialized storage tanks and safety measures.
