As the world is facing a critical energy challenge, there are several reasons why we can’t afford to ignore green hydrogen as an energy source.
In recent years, there has been a growing interest in green hydrogen. Green hydrogen is a clean fuel that is produced from renewable energy sources. It is seen as a way to help meet the world’s critical energy challenges and climate action goals.
Green hydrogen has the potential to play a major role in the future of clean energy. The production is expected to increase in the coming years as the technology develops and more countries commit to ambitious climate targets.
In this blog, we will explore the power of green hydrogen and why we can’t afford to ignore this new energy source.
What is Green Hydrogen?
Green hydrogen is a type of hydrogen that is produced using renewable energy sources. Compared to traditional hydrogen (also referred to as ‘grey’ or ‘blue’ hydrogen) which is produced using fossil fuels, green hydrogen has significantly lower carbon emissions as certified green hydrogen requires an emission reduction of >60-70% (depending on the certification body) below the benchmark emissions intensity threshold. This makes it a much cleaner and more sustainable option for powering hydrogen fuel cells and other devices.
Green hydrogen can be produced through a process called electrolysis, which uses electric current to split water molecules into hydrogen and oxygen. The hydrogen can then be used in fuel cells to generate electricity, or it can be stored for future use.
As the world looks for cleaner and more sustainable energy sources, green hydrogen is looking to play a big role in our future.
The Benefits of Green Hydrogen
Green hydrogen is one of the most promising renewable energy sources of the future. It is a clean, environmentally-friendly fuel that has the potential to power everything from cars and trucks to homes and businesses.
There are many benefits of green hydrogen, including the fact that it emits zero emissions when used. This makes it a great choice for reducing greenhouse gas emissions and fighting climate change. Additionally, green hydrogen is renewable and can be produced using a variety of different renewable energy sources, such as solar, wind, and water power.
Another benefit of green hydrogen is that it is highly efficient. For example, when used in fuel cells, green hydrogen can be around 2.5 times more efficient than gasoline. This makes it an excellent choice for powering vehicles and other high-energy applications.
Finally, green hydrogen will become increasingly affordable as technology advances.
The Drawbacks of Green Hydrogen
Hydrogen is often hailed as a clean energy source that has the potential to help us meet our climate goals. However, the process of producing green hydrogen is not without its drawbacks.
For one, green hydrogen production is currently very expensive and the implementation of green hydrogen infrastructure and research requires significant investments. The decrease in renewable energy prices has opened a new window of opportunity for its cost to become increasingly competitive. However, until costs come down, green hydrogen will likely remain out of the energy mix.
Additionally, green hydrogen production requires a lot of energy. The most common way to produce green hydrogen is through electrolysis, a very energy-intensive process compared to other fuels.
Finally, hydrogen is a highly volatile and flammable element, so it’s important to take safety measures to prevent leakage and explosions. Hydrogen is also odourless, which makes it difficult to detect leaks and can pose health and safety concerns.
The Bottom Line
As the world moves towards cleaner sources of energy, green hydrogen is an option we can’t afford to ignore. It provides a clean energy source that can help meet climate action goals and address many of the world’s energy challenges. While there are some drawbacks to be addressed, such as cost and scalability, the right investments in green hydrogen technology from governments and businesses will allow the world to capitalize on its potential for the future.
