What is Green Hydrogen?
Green hydrogen is hydrogen gas produced through renewable energy sources like solar, wind, or hydropower using a process called electrolysis. Electrolysis involves passing an electric current through water, causing the water molecules to separate into hydrogen and oxygen. This carbon-free method distinguishes green hydrogen from grey and blue hydrogen, which are derived from fossil fuels. Grey hydrogen is produced from natural gas without carbon capture and storage (CCS) technology, while blue hydrogen uses CCS to reduce carbon emissions. As a sustainable and environmentally friendly alternative to traditional fossil fuels, green hydrogen is expected to play a significant role in future energy systems.
How Green Hydrogen Works?
Producing green hydrogen requires electrolyzers powered by renewable energy sources. These devices use electricity to split water molecules into hydrogen and oxygen while capturing the hydrogen. Green hydrogen can be stored in high-pressure tanks, metal hydrides, or liquid organic hydrogen carriers (LOHCs), which enable safe and efficient storage.
Transportation of green hydrogen primarily relies on pipelines, trucks, and ships, with ongoing research into new methods to improve efficiency, reduce costs, and minimize environmental impacts.
The Future of Green Hydrogen
Green hydrogen holds substantial potential as a clean and sustainable energy source, with applications spanning from fuel for transportation to power generation and industrial processes.
As a crucial component in the global energy transition, green hydrogen aims to reduce greenhouse gas emissions and decrease dependence on fossil fuels. However, its widespread adoption depends on addressing challenges in production, storage, and transportation, alongside ensuring economic viability.
With technological advancements and an increasing focus on renewable energy sources, green hydrogen is expected to play a more significant role in the future. Experts predict that green hydrogen could supply up to 25% of the world’s energy needs by 2050, paving the way for a cleaner and more sustainable future. Additionally, green hydrogen can help countries achieve their climate targets under the Paris Agreement, further emphasizing its importance in the global fight against climate change.

Applications of Green Hydrogen
The versatility of green hydrogen makes it an attractive energy solution for various sectors. Some of its primary applications include:
- Transportation: Green hydrogen can be used as a clean fuel in fuel cell electric vehicles (FCEVs), including cars, buses, and heavy-duty trucks. FCEVs generate electricity from hydrogen through a chemical reaction with oxygen, producing water vapour as the only emission. This makes them a promising alternative to traditional internal combustion engine vehicles, reducing greenhouse gas emissions and air pollution.
- Aviation and Maritime: The aviation and maritime industries are exploring green hydrogen and its derivatives, such as ammonia and methanol, as alternative fuels. These industries face unique challenges in reducing emissions due to the energy density requirements of long-distance travel. Green hydrogen and its derivatives can help them achieve their sustainability goals and contribute to global efforts to combat climate change.
- Power Generation: Green hydrogen can complement intermittent renewable energy sources like solar and wind by providing stable and reliable power during periods of low generation. When the energy demand is higher than the available renewable energy supply, green hydrogen can be converted back into electricity through fuel cells or gas turbines. This enables efficient energy storage and utilization, promoting the integration of renewable energy into the grid.
- Industrial Processes: Green hydrogen can be used as a feedstock in energy-intensive industries, such as steel and cement production. By replacing fossil fuels with green hydrogen, these industries can reduce their carbon footprint and contribute to global emissions reduction targets. Green hydrogen can also serve as a feedstock for producing ammonia, methanol, and other chemicals, fostering a greener chemical industry.
