As the world continues to grapple with climate change, green hydrogen is increasingly being recognized as a potential game-changer in our quest for a sustainable future. Its promise of clean, efficient energy has piqued the interest of scientists, policy makers and investors alike. In this article, we delve into eight essential aspects of green hydrogen that you should know about.
Green Hydrogen: definition and Energy Potential
What is Green Hydrogen ?
Green hydrogen, also known as renewable hydrogen, is a type of hydrogen gas that is produced by water electrolysis powered by electricity generated from renewable energy sources such as solar or wind power. Unlike conventional methods of producing hydrogen which rely on fossil fuels and result in carbon emissions, green hydrogen production is carbon-free making it an environmentally friendly energy source.
The Energy Potential of Green Hydrogen
The energy potential of green hydrogen lies in its ability to store and transport energy effectively. It can be used across various sectors including those that are hard to decarbonize such as heavy industry, transportation and power generation. This makes it an integral part of strategies aimed at reducing greenhouse gas emissions.
As we explore the process of creating this potent renewable resource, let’s shift our focus towards its current and future production methods.
Current and Future Production Methods for Renewable Hydrogen
How is Green Hydrogen Produced ?
To produce green hydrogen, water molecules (H2O) are broken down into oxygen (O2) and hydrogen (H2) through the process of electrolysis. Although this method remains relatively expensive at present compared with traditional production techniques using natural gas, it’s crucial for achieving carbon neutrality goals.
Futuristic Production Techniques
As we move forward, more efficient and cost-effective methods of green hydrogen production are expected to emerge. This is largely driven by ongoing advancements in electrolyser technology and the increasing availability of cheap renewable electricity.
Having understood how green hydrogen comes to life, let’s examine the regulatory challenges it faces and the financing options available within Europe.
Regulatory Challenges and Financing Options for Green Hydrogen in Europe
Overcoming Regulatory Obstacles
Despite its numerous benefits, the journey towards mainstream adoption of green hydrogen isn’t without hurdles. High production costs and inadequate distribution infrastructure pose significant challenges. Additionally, safety concerns around storage and handling need to be addressed.
Financing Green Hydrogen Projects
In response to these challenges, various European countries have started investing heavily in supporting green hydrogen projects. France, for instance, has earmarked substantial funds with a view to achieving carbon neutrality by 2050 and producing up to 6.5 million tonnes of hydrogen annually by 2030.
As we continue our exploration of this promising energy resource, let’s compare its potential with that of electric batteries for clean mobility.
Comparison with Electric Batteries: the Future of Clean Mobility
The Case for Green Hydrogen Over Batteries
The advantages of using green hydrogen as a fuel source in vehicles extends beyond its zero-emission characteristic. When compared with battery-powered electric vehicles (BEVs), fuel cell electric vehicles (FCEVs) powered by green hydrogen have longer ranges and faster refuelling times.
Potential Applications for Green Hydrogen in Transportation
Apart from cars, trucks and buses, even trains are being developed that can run on green hydrogen. By 2024, pioneering projects featuring hydrogen-powered trains and trucks are expected to hit the roads and railways in France and other parts of Europe.
As we evaluate the many uses of green hydrogen, it begs the question: can it replace oil economically ?

The Decarbonization Potential
Green hydrogen’s production technique sets it apart as a truly decarbonized source of energy. However, it is critical that all electricity used for its production comes from renewable sources; otherwise CO2 emissions can still contribute to climate change.
Role in Energy Transition
Green hydrogen stands at the forefront of our quest for a sustainable future. As technology and supportive policies evolve, it becomes increasingly important to track developments in this sector from technological, economical, and environmental perspectives.
Let’s wrap up by discussing some investment strategies one could adopt for this low-carbon hydrogen market.

Riding the Green Wave
The surge in interest around green energy technologies presents numerous investment opportunities. Governments and private investors alike are recognising that low-carbon hydrogen could play a key role in efforts to mitigate climate change, sparking a wave of investment in the sector.
Long-Term Prospects
The long-term prospects for green hydrogen are promising. As production costs continue to reduce and the technology becomes more efficient and widespread, investments in this sector could yield significant returns.
In this rapidly changing landscape, green hydrogen has emerged as a crucial element in our global energy strategies. Its potential applications extend across sectors that have traditionally been difficult to decarbonize, while its environmental benefits make it an attractive solution for sustainable development. With ongoing improvements in technology and regulatory support, the future looks bright for this clean, green energy source.
