› Resources › Green Hydrogen: The Clean Fuel Powering a Sustainable Future

Despite the current dominance of fossil-fuel-based hydrogen production, there is a growing interest and investment in green hydrogen technologies due to expanding applications across various sectors and improving cost efficiency. The global trends show a surge in the demand for hydrogen and its projected growth. It emphasizes on the importance of transitioning from fossil-fuel-based to green hydrogen production methods.

Our world runs on fuel. From powering our cars to heating our homes, hydrocarbons like petrol and diesel have been the dominant source of energy for over a century. With the looming threat of climate change, however, the need for cleaner, more sustainable alternatives is paramount. This is where green hydrogen steps in, offering a revolutionary solution with the potential to transform our energy landscape.

Understanding Hydrogen – The Fuel, Not Just the Carrier

Unlike fossil fuels, hydrogen itself is a fuel. While it doesn’t exist in readily usable quantities in nature, it can be produced from various sources, including water. Green hydrogen, derived from renewable energy sources, stands out as a clean, sustainable fuel with zero pollution, serving not only as an energy carrier but also as a raw material. Its significance in combating climate change lies in its capacity to substitute fossil fuels in sectors that were previously challenging to decarbonize, alongside its potential as an energy storage solution.

This process produces zero carbon emissions, making green hydrogen a truly clean fuel. In a recently published article by Economic Times, billionaire Gautam Adani asserts green hydrogen as vital for India’s net-zero goals, proposing solar power’s model to cut costs, emphasizing the necessity of renewable leapfrogging for energy security and urban air quality.

But how is Green Hydrogen achieved?

Green hydrogen is produced through electrolysis powered by renewable energies such as wind or solar. The process involves using an electrical current to break down water molecules into oxygen and hydrogen using electrodes.

In 2022, the International Energy Agency (IEA) forecasted a demand of only 115 million tons by 2030, with new applications contributing less than 2 million tons. However, by 2050, the global hydrogen market could experience a significant surge, reaching between 600-650 million tons, possibly meeting over 20 percent of global energy requirements.

Benefits of Green Hydrogen

Over traditional fuels, Green Hydrogen boasts of several advantages:

• Clean Burning:

  As mentioned earlier, green hydrogen combustion produces only water vapor, eliminating harmful greenhouse gases and air pollutants.

• Versatile Fuel:

  Green hydrogen is a highly versatile fuel with applications across sectors. It can be used in:

  • Transportation:

    Powering fuel cell electric vehicles (FCEVs) with longer range and faster refuelling times compared to battery powered EVs.

  • Power Generation:

    Hydrogen can be used in turbines to generate electricity, providing a clean and reliable source of power, especially during peak demand periods

  • Industrial Processes:

    Green hydrogen can replace fossil fuels in numerous industrial processes, particularly in steel and cement production, which are major contributors to greenhouse gas emissions.

  • Energy Storage:

    Hydrogen can be stored and transported in gaseous or liquid form, offering a long-term energy storage solution for excess renewable energy.

• Energy Security:

  Green hydrogen production can be decentralized, relying on local renewable energy sources. This reduces dependence on fossil fuels and volatile energy markets.

• Raw Material for Clean Fuels:

  Green hydrogen is a key ingredient in the production of several clean alternative fuels, such as:

  • Synthetic Methanol:

    Combining green hydrogen with captured carbon dioxide can create clean-burning methanol for transportation and industrial applications.

  • Biogas/Synthetic Methane:

    Green hydrogen can be blended with biogas or used to create synthetic methane, a renewable source of natural gas.

  • Green Ammonia:

    Green hydrogen can be used to produce green ammonia, a clean-burning fuel for transportation and fertilizer production.

Future of Green Hydrogen Industry

Fuelled by the urgency of climate change mitigation, green hydrogen is poised for a dramatic rise. As renewable energy sources like solar and wind become more prominent, green hydrogen offers a solution for both storing excess energy and decarbonizing various sectors.

Technological advancements are making green hydrogen production more cost-competitive, while a shift in policy landscapes with government incentives is further propelling its adoption. The future of clean energy is getting a major boost from green hydrogen. The worldwide market for green hydrogen was valued at approximately USD 6.26 billion in 2023. This number is forecasted to exceed USD 165.84 billion by 2033, with a projected compound annual growth rate (CAGR) of 38.77% from 2024 to 2033.

Among some of the top global companies investing in green hydrogen are AMEA Power, Linde, First Hydrogen, and Lhyfe. AMEA Power focuses on developing a 10,000 MW green hydrogen project in Egypt, while Linde supplies PEM electrolyzer technologies and advocates for hydrogen solutions. First Hydrogen offers integrated green hydrogen-centric solutions for zero-emission fleets, and Lhyfe is a producer and supplier of green and renewable hydrogen, pioneering offshore hydrogen production.

Green hydrogen is experiencing a surge in demand and attracting big energy companies for several future-oriented reasons:
