Understanding the element of the stars. Basic facts about hydrogen.
Hydrogen is the most abundant of all chemical elements, making up roughly 75 % of the universe’s elemental mass, which is why it is also called the universal element. As an industrial gas, it is well known and widely used for a variety of applications, for example in the desulphurisation process of crude oil and the production of ammonia.
Global energy. Hydrogen can be produced from many sources.
Currently, 98 % of the world’s hydrogen production is based on fossil fuels – with steam reforming of natural gas being the dominant process. This is a very economical and efficient method, but, like all fossil-based processes, also produces CO2. On the other hand, steam reforming also works with hydrogen-rich biogas, a method that creates a neutral CO2 balance.
Another eco-friendly H2 production process is electrolysis, i.e. splitting water into its main components O2 and H2 with an electric current. With a renewable energy as the primary energy source, this method offers the possibility of a completely emission-free hydrogen energy cycle.

With its innovative developments and enthusiasm for research, the Linde hydrogen generation is paving the way for the world’s cleanest energy carrier. From well to wheel, our expertise covers virtually all steps in the hydrogen technology chain – from production, storage and distribution through to entire refuelling systems and on-board storage equipment for hydrogen vehicles.
Statement by Professor Dr Wolfgang Reitzle, CEO of The Linde Group.
Dear Ladies and Gentlemen,
Worldwide energy consumption is increasing steadily in line with the continuing growth of the world's population and the economic development of newly industrialising countries. Therefore, today more than ever we are faced with the problem of finding an environment-friendly energy source. In response to this global challenge, we are committed to researching and further developing hydrogen technology. Due to its special properties, hydrogen is the ideal storage medium for a wide range of primary energies, including electricity generated from renewable energy sources. This makes it the most important link in a sustainable energy value chain which is completely emission-free from beginning to end.
As an experienced gas specialist and one of the world's largest hydrogen providers, Linde is best positioned to contribute to achieving these goals. In recent years, besides Linde, other companies have also made major technological breakthroughs designed to create a more efficient and environmentally friendly way of producing, storing and utilising the energy of hydrogen. These results bring within reach the vision of a sustainable solution, which is equally suitable for everyday use, for our growing transport and mobility problems.
However, for this vision to become reality, it requires your personal commitment as a possible development partner, potential consumer or future user of this technology. Therefore, I am delighted that you are interested in this website and would like to invite you to inform yourself about the numerous advantages and perspectives offered by hydrogen-based mobility – and to join us in working towards its implementation.

LH2 dispenser
CGH2 dispensers
The LH2 dispenser for liquid hydrogen allows for rapid fuelling. The unit operates at a fuelling pressure of 4 bar and a cryogenic temperature of -253 °C. It is the same patented model used at the Linde Hydrogen Center in Munich.
Fuel cell
The unit can be operated self-sufficiently using an integrated, emission-free hydrogen fuel cell as an on-site power supply. That way, the refuelling unit can be operated independently from an external electric power source.
