Green hydrogen is a type of hydrogen that is produced through the electrolysis of water using renewable energy sources such as solar or wind power. It is considered a key technology in the transition to a climate-neutral energy system because it is a clean and renewable source of energy that can be used in a variety of applications.
As a zero-emission energy carrier, green hydrogen can be used to power vehicles, heat homes and buildings, and generate electricity. It can also be used as a storage solution for excess renewable energy, and as a feedstock for various industrial processes.
Green hydrogen can also help to decarbonize sectors that are difficult to electrify, such as heavy-duty transportation, aviation and shipping, and industrial processes like steel and cement production.
Incorporating green hydrogen into a climate-neutral strategy can help to reduce greenhouse gas emissions, increase energy security, and promote economic growth. However, it is important to note that the development of green hydrogen infrastructure and technologies is still in its early stages, and significant investments and policy support will be needed to accelerate its deployment at scale.
Additionally, it's important to consider the whole hydrogen value chain, from the production to the end-use, and ensure that the hydrogen is produced, transported, stored and used in an environmentally sustainable way.
