Why hydrogen?
The basic precondition for the application of hydrogen in all sectors concerned is the transition to a low-emission or zero-emission economy. As for the constant efforts of states across all continents, new alternatives for the development of climate-neutral technologies are sought. The European Union itself has set the goal of achieving complete climate neutrality for the year 2050, i.e., capturing and storing the same amount of greenhouse gas emissions as will be released into the atmosphere. The very fact of the development of renewable energy sources across the Member States then creates room for stabilizing their unpredictable electricity production. In this case, hydrogen will play the role of an energy carrier, which is especially suitable for seasonal accumulation and some mobility applications.
What is hydrogen?
Hydrogen is the lightest gaseous chemical element forming up two-thirds of the entire cosmic mass. It is estimated that it makes up more than 30% of the total mass of the Sun. It is the third most widespread element on Earth, yet it occurs almost never as a single molecule because it is highly reactive and forms compounds immediately. Hydrogen is ubiquitous, whether in the form of water, natural gas, or methanol. As the simplest and lightest element, it disperses into the air very quickly when escapes. When escaping, hydrogen does not pollute the environment in any way. It is an emission-free substance that is non-toxic and odourless. Hydrogen is a combustible element, but it does not support combustion, and burns with a pale blue flame.
