What is Green Hydrogen, or renewable hydrogen? We share with you all the information about the energy of the future.
Before we begin, the first step is to know that hydrogen is the most abundant chemical element in nature, the ‘partner’ that contributes two atoms to oxygen to create water (H2O). An element that burns, gives off energy and can be converted into a fuel capable of moving cars, heating houses or powering factories.
It is the perfect substitute for oil or natural gas derivatives, since it can take their place without polluting the planet. The problem, as Alberto Sanz rightly commented in his article, “‘Green hydrogen’, the ingredient in every energy transition sauce”, is that, despite being the most abundant element on Earth, hydrogen is not easy to obtain.
Hydrogen can be converted into a fuel capable of moving cars, heating houses or powering factories.
Because, to be combustible, it needs to be by itself, and in nature it is always found with other elements, such as coal, natural gas or water. In other words, to obtain hydrogen, it needs to be extracted from these natural resources. And the difference between conventional hydrogen and this desired ‘green hydrogen’ lies in its extraction. But then, what is green hydrogen?
“Green hydrogen generation is an alternative to reduce emissions and ultimately take care of our planet”
Green hydrogen: beyond electricity.
The hydrogen produced from renewable energy sources is called green hydrogen. This accumulated green hydrogen is expected to be introduced into many energy sectors.
That is why green hydrogen generation has become an alternative to reduce emissions and ultimately take care of our planet.
Through the most ambitious energy transformation, the IEA has determined that 25 % of the final energy demand in 2050 will come from hydrogen-related transformations. This is particularly important in the TRANSPORT SECTOR .
Financial aids for electric mobility
In our previous post, Financial Aids for Electric Mobility, we already mentioned the financial aids announced by the Government for the automotive industry, a total of 3.75 billion euros to support clean and electric mobility. But how does a hydrogen fuel cell work?
Through the use of fuel cells (road freight transport, fork lifts, stationary cells, etc.), hydrogen is converted back into electricity but it is also present in the production of advanced biofuels.
Green hydrogen has already started to be used in the industrial sector to produce, for example, green ammonia or green methanol, and in the heat sector, where it is being introduced into the natural gas grid as hydrogen or by means of methanation with CO2. capture.
