Hydrogen is the planet's most abundant chemical element
However, it is never found alone; it typically combines with other elements like oxygen to form water or with carbon to create organic compounds.
Humanity has long utilized hydrogen as a raw material in the chemical industry and metallurgy, as well as a fuel. However, since it cannot be sourced in its pure form from nature, it must be produced through various methods. The process used to produce hydrogen ultimately determines whether it serves as a clean and sustainable fuel.
When we refer to green hydrogen, we mean hydrogen produced without emitting pollutants, making it a sustainable fuel. It is increasingly recognized as a crucial energy source for achieving global decarbonization goals and meeting 2050 climate commitments.
Below, we will explore why green hydrogen is crucial for reducing greenhouse gases, how it is produced, and the challenges it must address to become the fuel of the future

OUR TEHNOLOGY
Key Benefits of Green Hydrogen Compared to Blue and Grey Hydrogen
Grey hydrogen is produced from natural gas using steam methane reforming (SMR) without capturing the carbon dioxide emissions. This process releases significant amounts of CO2 into the atmosphere, making grey hydrogen the least sustainable and environmentally friendly form of hydrogen
grey hydrogen
green hydrogen
Blue hydrogen is produced from natural gas through a process called steam methane reforming (SMR). During production, carbon dioxide emissions are captured and stored, or utilized in other processes, which reduces its environmental impact
blue hydrogen
Also known as renewable hydrogen, green hydrogen is produced through the electrolysis of water. The key factor is that this process relies entirely on renewable energy sources, resulting in zero pollutant emissions and making it the cleanest and most sustainable form of hydrogen

Grey hydrogen is produced from natural gas using steam methane reforming (SMR) without capturing the carbon dioxide emissions. This process releases significant amounts of CO2 into the atmosphere, making grey hydrogen the least sustainable and environmentally friendly form of hydrogen
While hydrogen itself is a clean fuel, grey hydrogen’s reliance on fossil fuels negates its environmental benefits. This delays the transition to greener alternatives, like green hydrogen, which is produced using renewable energy and emits no carbon, making grey hydrogen a problematic choice for the planet
Grey hydrogen, produced from natural gas through steam methane reforming (SMR), emits large amounts of carbon dioxide (CO2). For every ton of hydrogen produced, about 9 to 12 tons of CO2 are released, making it a significant contributor to global warming and climate change
Why is gray hydrogen problematic for the planet?
Blue hydrogen is produced from natural gas, similar to grey hydrogen, but with carbon capture and storage (CCS) technology to reduce CO2 emissions. While this might seem like a cleaner option, the process is far from perfect. A significant portion of CO2 still escapes into the atmosphere, and the energy-intensive nature of CCS often relies on fossil fuels, which further contributes to greenhouse gas emissions
Why is blue hydrogen problematic for the planet?
Green hydrogen plays a crucial role in combating climate change by offering a viable alternative to fossil fuels, particularly in sectors and applications that have been challenging to decarbonise. Beyond replacing fossil fuels, green hydrogen also holds significant potential as an energy storage system
Produced using renewable energy, green hydrogen is a clean and sustainable fuel with zero emissions. Moreover, its environmentally friendly nature positions it as a key resource, not only as an energy carrier but also as a valuable raw material in various industries
Achieved through a process of electrolysis powered by renewable energies like wind or solar, green hydrogen is produced by using an electrical current to split water molecules into oxygen and hydrogen at the electrodes. This method ensures that the hydrogen is generated in an environmentally friendly manner
WHAT IS GREEN HYDROGEN, AND HOW DOES IT WORK?
Secondly, green hydrogen is highly versatile and can be used across various sectors. It serves as a clean fuel for transportation, such as hydrogen fuel cell vehicles, and can also be used in industrial processes and power generation. Additionally, green hydrogen provides an effective solution for energy storage, helping to balance supply and demand by storing excess renewable energy and delivering it when needed
Green hydrogen offers several key benefits as a fuel. Firstly, it is produced through electrolysis powered by renewable energy sources like wind and solar, which means it generates zero carbon emissions. This makes green hydrogen a vital tool in reducing greenhouse gases and mitigating climate change, while also contributing to cleaner air and a more sustainable energy system
