Green hydrogen is the ultimate ally to successfully advance the transition towards clean energy and achieve decarbonisation, and it is the fuel that we’ve been waiting for. Since it is produced using renewable energy sources, green hydrogen does not emit greenhouse gasses.

It is a fuel that is safe to transport: it can be taken wherever it’s needed. It can also be stored, offering an energy supply that is not jeopardized by adverse weather conditions, unlike other technologies. All of these characteristics of hydrogen make it key to energy decarbonisation and the fight against climate change, one of the goals set by the United Nations in its Sustainable Development Goals (SDGs) at the 2015 United Nations Climate Change Conference.

Green Hydrogen: Carbon Free, Renewable and Readily Available


Hydrogen is the most abundant element in the universe, and its supply is virtually limitless. It can be used on site where it is produced, and it is also safe to transport and store. When converted into a carrier, such as ammonia, a zero-carbon fuel that has many applications, green hydrogen is a transportable renewable energy.

One of the most prominent advantages of green hydrogen is that, unlike biofuel or hydropower, it doesn’t require large areas of land for its production. It can be produced wherever there is water and cheap electricity, and it can be used for multiple applications. Unlike other sources of power or heat, green hydrogen can be stored in large quantities for extended periods of time. It can also be produced from excess renewable energies wherever there is sun, wind or any other renewable source and stored in large amounts for a long time. This makes it the ideal candidate for large-scale deployment.

Hydrogen has the highest energy content of any common fuel by weight. High pressure gaseous and liquid hydrogen contain almost 3 times as much energy as fossil fuels, so less of it is needed to do any work.

A clean alternative with many applications


Green hydrogen is a power source created using renewable energy instead of fossil fuels. An electric current powered by solar or wind energy is used to split water into hydrogen and oxygen; the resulting hydrogen is pollutant-free. Since green hydrogen is produced through the electrolysis of water, the only byproduct is oxygen and water.

In the short term, there are 3 immediate uses for green hydrogen:

Replace all uses of fossil-based hydrogen
Use it in fuel cells in medium to heavy-duty land transport
Applications in aviation and shipping, transport, manufacturing and industry, using e-fuels based on greed hydrogen

Additionally, green hydrogen can be used in both gas or liquid form, and it can be blended with existing gas pipelines to power household appliances and industries. Thus, green hydrogen will play an important role in balancing the intermittent supply modalities with the challenging end-user demands, avoiding the need for significant early investment to upgrade grid infrastructure.

Advantages of Hydrogen Fuel Cells


Hydrogen fuel cells present several advantages over conventional power sources. They can be used to power machines and devices that use electricity, such as electric vehicles or electronic devices, and be used as backup power to secure the supply. Unlike traditional batteries, hydrogen fuel cells don’t need to be recharged and won’t run down, as long as they are supplied with hydrogen fuel.

Moreover, hydrogen fuel cell technology is able to provide a high-density energy source, with a good energy efficiency, which enables a higher energy production per pound of fuel than other alternative energy sources.

And since hydrogen fuel cells don’t release greenhouse gas emissions, they don’t have a carbon footprint while in use, the air quality isn’t impacted, and pollution rates are reduced. Furthermore, hydrogen fuel cells don’t produce visual or noise pollution, like other sources of renewable energy, such as wind power. Much like electric cars, hydrogen powered vehicles are silent.

Improved Efficiency 

the internal combustion engine of a conventional car has a 25% energy efficiency, whilst hydrogen fuel cells generally range from 40 to 60% energy efficiency.


in recent years, hydrogen fuel cell technology has proven itself in adverse conditions, such as cold temperatures as low as -40ºC, and tough weather like hurricanes and winter storms.

Zero-Emission Power 

unlike battery acid or diesel fuel, hydrogen fuel cells don’t produce any harmful emissions, eliminating the costs of handling and storing toxic materials. The only byproducts are heat and water, making hydrogen fuel cells a sustainable and zero-emission power source.


hydrogen fuel cells are a scalable product that can be designed to meet the power needs of various customers, whether it be for on-road electric vehicles, material handling fleets or stationary power, optimizing costs.

Lower Operational Costs 

since hydrogen fuel cells eliminate the need to change, charge and manage batteries, they reduce labor, time, space and peak power demands. These units run longer than lead-acid batteries and can be fueled in a matter of minutes, thus substantially reducing the vehicle and personnel downtime. Compared to combustion generators for stationary power and batteries, fuel cells save time and money on maintenance.

The Future of Green Hydrogen


The plans and projections for the future of green hydrogen and fuel cells include replacing fossil-based hydrogen with renewable hydrogen in industrial processes, transportation and manufacturing, reducing substantial amounts of carbon emissions and making a significant contribution to the climate global targets. In addition, the use of hydrogen will contribute to energy independence and reduce market fluctuations.

One of the challenges that hydrogen fuel cells face is decreasing its cost without compromising performance. The cost of building and maintaining hydrogen stations also needs to decrease in order for the market to be able to support a hydrogen-based economy.

With the right legal framework and timely investments, renewable hydrogen is estimated to be cost-competitive by 2030
