Why hydrogen:

Renewable energy source a prerequisite for sustainability

  • The most common occurrence on earth and in space. Indeed it is, although on earth hydrogen is almost always bound in molecules and thus needs to be extracted. The most common and cleanest way to extract hydrogen is from water using renewable energy, most commonly from photovoltaic or wind power. Ideally, these RES sources should be located on the roofs of halls, at industrial parks, etc., so that they do not take up often unnecessary arable land.
  • The future of these RES is then decentralised and so-called SmartGrids, which can cleverly connect hundreds and thousands of small PV plants into a very efficient source of electricity.
  • High energy density - one kg of hydrogen represents approximately 33.3kWh of energy, which is about 3 times more than in 1 litre of petrol and about 15 times more than in today's best batteries/accumulators
  • Locally produced, with no major environmental impact. This is another prerequisite for sustainability, minimising the need to transport over long distances, the need to build large process units, pipelines and product lines.
  • For transport vehicles, it provides a range equivalent to internal combustion engines and also provides rapid refuelling in minutes. This is due to the fact that hydrogen, like petrol, is an energy carrier. The advantage is that there is no need for such a dense network of filling stations, and there are no extreme requirements for reinforcement of the electricity grid
  • Zero local emissions of vehicles, which also clean the air in their surroundings. No it's not marketing, not only is it inherently an electric vehicle, but in addition, clean water actually comes out of its "exhaust", thus purifying the surrounding air as it is sucked in. This is due to the chemical process in the fuel cells. In addition, there is also heat generated, which can be used to heat the vehicle in the winter months and thus increase the efficiency of the system.
  • Higher efficiency - the "dead" load is incomparably lower, unlike batteries, which is particularly important for freight and air transport. Nor company can afford to carry several tonnes (neither shipping) of batteries. The aim is maximum efficiency. It is also about time spent charging/tanking. There is a clear advantage here on the hydrogen propulsion side.



There is also a great future in this direction in the aviation industry, where payload capacity is absolutely crucial. Whether we are talking about pure hydrogen or its use as a part of synthetic fuels.

  • It enables truly ecological, local and sustainable energy management, and not just in terms of reducing CO2 emissions. If we look at the whole process, it is obvious that, especially on a smaller scale, hydrogen can bring local self-sufficiency and, above all, help the overall sustainability of many sectors. It can be produced locally and used locally now or with a delay.

  • It can be used as a carrier of surplus energy (from PV) or as a source of electrical or thermal energy, always with zero local emissions. And not only in large buildings, but for example in family houses, where it will not matter whether you store it for the next night or the next winter.
