A willingness to embrace all technologies is an immediate priority!

Carbon-neutral powertrains are essential for achieving climate goals. A willingness to embrace all technologies to achieve these goals is crucial and using hydrogen – as an infinitely available, renewably generated energy carrier that is easy to store and transport – to drive powertrains is a vital part of this. Hydrogen-fuelled, carbon-neutral internal combustion engines offer an outstanding solution in many areas. Hydrogen engines also have a long service life, after which they can be easily recycled using established processes.

Unlike electricity, hydrogen can refuel machinery out in the field

Carbon-neutral agricultural machinery has the potential to reduce carbon emissions significantly in the food production industry. Agricultural machinery requires powerful, robust powertrain solutions that are as lightweight as possible to keep soil compaction to a minimum. This is where hydrogen comes in as a carbon-neutral energy carrier with a high energy density. What’s more, agricultural machinery with hydrogen engines can be quickly refilled out in the field.

Hydrogen is more than powerful enough

Today’s infrastructure will need to be maintained and constructed long into the future. To make these activities more environmentally friendly, powerful and durable carbon-neutral powertrains are needed for the excavators, cranes, rollers, HGVs, dump trucks and other machinery required to move heavy loads. These powertrains must be able to withstand dust, dirt, heat, freezing conditions, water, snow and ice.

100% ready for action

Climate change is increasing the risk of extreme weather events. This means that rescue teams – usually consisting of volunteers from the general public – need to be ready to spring into action around the clock to save lives and property in extreme conditions. Only reliable and robust carbon-neutral machinery has the power and endurance to provide the swift help needed in these high-pressure situations. Hydrogen engines were born for this task.

We would like to take this opportunity to thank all volunteers with the fire service, the German Federal Agency for Technical Relief (THW) and other civil defence organisations for their tireless work.

The Board of Allianz Hydrogen Motor e. V. focuses on …

  • Professional lobbying in the political and social sphere based on scientific publicly accessible information.
  • Identification of relevant interfaces/stakeholders in politics and associations or the coordinated creation of framework conditions (e.g. through public funding) for projects to demonstrate the feasibility and short-term availability of a reciprocating-based hydrogen drive solution
  • The expansion of the public image "Hydrogen = Fuel Cell" to include the reciprocating engine solution as a further "zero impact" technology
  • Demonstrating the economic/ecological perspective (TCO and CO2 neutrality, concentration on suitable CV "use cases",
  • Argumentation for coexistence with other powertrain  solutions through differentiation)
  • Support for strategic planning and communication with all those involved inside and outside the alliance and the involvement of necessary political bodies, taking into account a non-partisan, common position
  • The creation of an exchange platform for stakeholders from infrastructure, fuel production for use and targeted promotion of discussion
  • The early detection of technical and other risks and the development of solutions
  • The promotion of green hydrogen sharing with fuel cell and hydrogen engine
  • The socio-economic aspects of the importance of technology for society
