As the world moves towards clean energy and carbon emissions reduction, green hydrogen is emerging as a promising solution. So What is green hydrogen? ?, What are the advantages and disadvantages of green hydrogen? and why is it important? Let's learn about the important applications of green hydrogen in today's life through the article of Green In down here!
1. What is green hydrogen?
Green hydrogen, also known as GH2, is hydrogen produced using renewable or low-carbon energy. Compared to traditional hydrogen, produced by steam reforming from natural gas, grey hydrogen, green hydrogen has significantly lower carbon emissions. - According to wikipedia
2. Applications of green hydrogen in various fields
Applications in heavy industry
Green hydrogen plays an important role in the industrial sector, especially in the steel industry. It is used as a reducing agent to remove oxides in iron ore, and also contributes to the production of oxygen and acetylene – important components in the welding and cutting of metals.
In addition, green hydrogen is also a clean energy source that replaces fossil fuels in industrial boilers. It helps reduce greenhouse gas emissions and limit negative impacts on the environment. With the ability to bring high efficiency and sustainability, this type of fuel is being prioritized by many businesses in the heavy industry sector.
Energy storage
Currently, there are many green hydrogen storage methods being researched and widely applied, including:
- Compressed gas form: Hydrogen is compressed at high pressure for storage and transportation.
- Liquid form: Store hydrogen at extremely low temperatures in specialized containers.
- Absorption in materials: Some materials such as zeolites have the ability to absorb hydrogen for more efficient storage.
Green hydrogen storage systems are applied in many fields, such as powering hydrogen-fueled vehicles and supporting energy storage from renewable sources.
Clean, renewable energy source
Green hydrogen is produced through the electrolysis of water, which separates hydrogen and oxygen without producing harmful emissions. The oxygen can be released into the air, while the hydrogen can be used as fuel or further recycled into clean energy.
Thanks to this property, green hydrogen not only saves resources but also contributes to reducing environmental pollution. Green hydrogen also creates a sustainable and eco-friendly renewable energy source.
Applications in daily life
In the household sector, green hydrogen can be produced from recycled materials, contributing to reducing plastic waste and creating useful products such as furniture, household appliances and children's toys.
With its durability, moisture resistance, fire resistance and ability to withstand harsh environmental conditions, materials made from green hydrogen are becoming the optimal choice for consumers interested in green and sustainable solutions.

3. Advantages and disadvantages of green hydrogen
3.1. Advantages of green hydrogen
- Environmentally friendly fuel: Green hydrogen only emits water during use, does not generate polluting emissions, helps protect the environment and is safe for human health.
- Renewable and sustainable: Produced from abundant natural resources, green hydrogen is infinitely renewable, contributing to a sustainable energy system.
- Easy to store: Green hydrogen can be stored in dedicated tanks as compressed gas or liquid, ensuring long-term storage without loss of quality.
- Ease of transport: Due to its lightweight nature, green hydrogen can be transported more easily than many other fuels. Compressed hydrogen tanks can be handled more flexibly than lithium batteries, optimizing transportation and distribution.

3.2. Disadvantages of green hydrogen
Although green hydrogen offers many outstanding benefits, its widespread development and application still face many challenges, including high costs and policy factors.
- Higher production costs than grey hydrogen: Previously, the production of green hydrogen was significantly more expensive than grey hydrogen. However, thanks to the development of renewable energy sources, this cost is gradually decreasing.
- Requires large investment capital: According to experts' forecasts, in the coming years, hundreds of billions of USD will be needed to build infrastructure and develop green hydrogen production technology globally.
Thus, despite the high initial costs, green hydrogen is still considered a potential investment opportunity with the potential to generate large economic benefits in the future.
4. Potential of green hydrogen in Vietnam
According to the Ministry of Industry and Trade, research from the Institute of Energy shows that the demand for green hydrogen in economic sectors in Vietnam is increasing significantly. This opens up great opportunities for development, especially as production, storage and distribution technologies continue to improve.
Although the application of green hydrogen is still limited at present, with advances in electrolysis technology and falling costs of renewable energy, this fuel could become more competitive by 2030.
In Vietnam, with its commitment to achieve net zero emissions by 0 at COP2050, it is actively promoting the clean energy transition. The expansion of solar and wind power projects is a clear demonstration of this determination. At the same time, through the US$26 billion Just Energy Transition Partnership (JETP) agreement with the cooperation of many international organizations, Vietnam is creating a solid foundation for the development of green hydrogen in the future.

5. Conclusion
The above article has clearly explained to you about What is green hydrogen?, applications of green hydrogen, potential of green hydrogen in Vietnam,... Green hydrogen is gradually becoming one of the important clean energy solutions, contributing to minimizing negative impacts on the environment and moving towards sustainable development.
