Initial situation

The EU member states and 196 contracting parties committed to comply with the Paris Climate Change Agreement 2015.Under the pressure of the impending climate catastrophe if the 1.5 ° C climate targets were exceeded, the EU member states - starting from 2005 - set themselves the goal of reducing 40% of CO2 greenhouse gas emissions, 32% renewable energy technologies and measures to increase energy efficiency also by 32%.

Business area

Hydrogen eMobility AG abbreviated to HeM AG) has taken on the task in its business field for effective climate and environmental protection to build up a nationwide filling station infrastructure for hydrogen in Austria and in the EU countries together with cooperation partners and to provide them with a low-cost bio- hydrogen.

The production of hydrogen

is however a question of costs and thus the affordability. Decisive for a cost-effective bio-hydrogen production is the availability of favorable green electricity for the electrolysis.

The availability of green electricity from wind power is extremely volatile at 1,500 hrs / year, from photovoltaics at 1,000 hrs / year and from hydropower at 5,500 hrs / year because of its dependence on sun, wind and weather. This results in a higher electricity price and an additionally required expensive hydrogen storage increases the price of this bio-hydrogen again considerably.

Bio - hydrogen from wood energy, however, is available to customers around the clock with more than 8,000 hours / year!

The green electricity from the EU

- wide patented CHP - REDOX - HGKW (wood gas power plant) with KD - dryer in combination with electrolyzer is the alternative for a particularly cost - effective bio - hydrogen production, by additional profits such as the sale of heat for district heating and pure oxygen for sewage treatment plants, industry, etc.

The raw material is wood, in many cases from wind breakage and bark beetle infestation, which the forestry and sawmill companies want to profit from lucratively.


To implement the global commitment to comply with the 2015 Paris Climate Targets, patents granted by inventor & patent holder Dipl.-Ing. Walter Sailer to the 2 in 24 EU countries are effective technologies for reducing greenhouse gas emissions and increasing energy efficiency.

USP of HeM AG:

Supply of bio-hydrogen with highest availability and lowest costs!

Hydrogen mobility in Austria starts with the public transport

With pollution-free fuel cell buses our desired destinations can be reached quickly, comfortably and with lower noise levels. The buses liberate Austrian cities from fine dust, bad smell, CO​2 a​nd nitric oxides.

the modular construction of hydrogen filling stations

The construction of hydrogen filling stations in Austria will be carried out in three steps -

Hydrogen eMobility AG with its cooperation partners takes responsibility for operational tasks including financing, network planning, permit, procurement, construction and business.


Hydrogen filling stations for buses in public transport

The strategic focus of the extensive filling stations’ network construction lies primarily on buses. This provides immediately applicable and significant possibilities for saving hundreds of thousands tons of carbon dioxide.

Hydrogen filling stations for logistic companies

In the second step a public expansion for vehicles in the field of distribution logistics is advised. Our customers are vehicle owners in public services and private delivery services.

Hydrogen filling stations for cars

Der finale Schritt im Ausbau eines österreichweiten Wasserstofftankstellen- Netzes liegt im Bereich der PKW’s. Tankstellen nicht nur an Autobahnen und in Ballungszentren, sondern überall dort wo es Wasserstoff-fahrzeuge gibt.

The power of hydrogen

The only emission from hydrogen-powered vehicles is steam. The energy conversion principle works as follows: Hydrogen combines with oxygen from the air in the fuel cell to produce water and electricity, with which it drives an electric motor. Hydrogen enables the usage of pollution-free vehicles that are capable of reaching long distances at short refuelling times. This makes them a great alternative to vehicles powered solely by electricity.

Hydrogen will contribute
to a better future,

help Austria reach its goals in regard to decarbonisation and climate at a faster pace,

store generated power to convert it into electricity again.

With hydrogen, Austria will be less dependent on fossil-fuel imports.

Hydrogen will open up possibilities for new business lines and a big part of net domestic product will remain in Austria.

The origin of hydrogen

Hydrogen is obtained through the electrolysis of water. Together with other renewable energy sources this can bring significant advantages: Solar PV farms and wind farms often produce surplus electricity and have to be disconnected from the grid if the energy is not consumed entirely. However, the surplus electricity can be used to generate hydrogen through electrolysis. A further method for producing hydrogen is through steam reforming.
