Messe Frankfurt Energy4Mobility Series Examines Hydrogen Fuel

Messe Frankfurt Energy4Mobility Series Examines Hydrogen Fuel

Experts at the talk agreed that hydrogen is needed for emission-free mobility.

Messe Frankfurt, one of the world’s leading trade fair, congress and event organizers, announced that its Energy4Mobility Talk series recently focused on the topic of the role hydrogen will play in carbon-neutral mobility.

The transport sector is responsible for 20% of total CO2 emissions in Germany. In contrast to many other sectors, greenhouse gases in transport have still increased in recent years, by 7% since 1990. According to the Climate Protection Act, CO2 emissions are to be halved by 2030 and reduced to zero by 2045. But which alternative fuels are sufficiently available and can be used quickly and efficiently?

Experts from ARTHUR BUS, Cryomotive, Gumpert Automobile, Hydrogen Europe, Linde, Mobil in Deutschland and UnternehmerTum agreed that hydrogen is needed for emission-free mobility.

“We created the expert talk series because there will be no mobility turnaround without alternative-drive energies,” said Michael Johannes, vice president of mobility and logistics for Messe Frankfurt. “Messe Frankfurt therefore wants to provide a platform for this topic and give important players the opportunity to present their innovative projects and ideas, to exchange ideas and to network.”

Hydrogen Important for Future

Matthias Braun, Advisor Aramco Research Center (Paris), added, “I very much welcome the fact that Messe Frankfurt is organizing this Energy4Mobility talk, which I am happy to support. There are several types of drive systems, and they all have to compete with each other. Hydrogen is a very important future type of alternative fuel. It’s very good that speakers from different types of transport, including trucks and sports cars, and also from the energy, service, etc. sectors come together here and network.”

The Aramco Research Center Paris is involved in hydrogen, among other things. Braun explains: “Aramco is currently working with Hyundai and Bosch in Vienna on a new generation of hydrogen combustion engine.” Aramco is also pursuing the goal of supplying Germany with green hydrogen in the future.

Assembly Line Needed

In his presentation on “Reasonable Use of Hydrogen in Transport”, Dr. Ing. Simon Herzog, senior project lead for UnternehmerTUM GmbH, used the example of a long-haul flight to illustrate that it would not be possible to completely electrify all modes of transport. Hydrogen will play an important role in the future, especially since it can be assumed that the costs for hydrogen will decrease. Germany will not become a major hydrogen producer, Dr. Ing. Simon Herzog summed up and explained further: “When it comes to hydrogen, one can see that especially in regions around the world where there is cheap electricity, there is a strong focus on hydrogen, above all in Norway and in some regions in the United States of America. Germany in particular is comparatively well-positioned as a technology supplier, but we will most likely not be the country that will produce hydrogen on a large scale because it is a very energy-intensive endeavor.”

Dr. Ing. Simon Herzog summed up: “Like Henry Ford, who made the car a mass product with the invention of the assembly line, we need an assembly line production for hydrogen and all the components involved in hydrogen.”

State of the Art

The fact that hydrogen refueling has been possible for many years and that the technology is state of the art was emphasized by Thomas Schaefer, business development manager for Linde GmbH, in his presentation on efficient refuelling technology for H2 vehicles. In the meantime, Linde has built various hydrogen fuelling stations worldwide, offering all types of fueling for cars, trucks, buses, trains and other commercial vehicles. At the moment, there is also the issue of green hydrogen, which is not easy to implement, as this not only affects production itself but also transport. But this is only a question of time.

“With the advancing energy turnaround towards renewable energies, green hydrogen will be available,” said Thomas Schaefer. Globally, there is no energy problem; in Africa, for example, there is 200 times more energy than is consumed locally.

“There is no energy problem, but a distribution problem,” Schaefer explained.

Cryopressure Hydrogen

Daniel Duschek, head of requirements management and RCS Cryomotive GmbH, spoke on the topic of cryopressure hydrogen for heavy-duty transport. He pleaded for a set of rules and the establishment of an international standard on hydrogen.

“We need a uniform standard for the suppliers,” Duschek explained. “It cannot be that I am allowed to install the product in one application and not in another because higher safety requirements have to be met there. There are different guidelines here that need to be harmonized.”

As far as the work on corresponding regulations is concerned, Germany is quite active here: “We have the know-how that we can describe new technologies, that we can distinguish them from existing technologies and that we can use the synergies. In Germany, we have a very strong community in this segment that supports the whole thing and continues to build it up in the international segment.”

Standards also need to be developed for the infrastructure; for example, there are many different systems for refueling hydrogen.   

Shaping the Future

The start-up ARTHUR BUS GmbH has set the goal of shaping the future of emission-free mobility.

“We want to solve the challenges of modern mobility — and we want to do it now,” said Philipp Glonner, CEO and cofounder of ARTHUR BUS GmbH. “This requires accessible and affordable solutions. The first solution focuses on public transport, as ARTHUR can make an immediate and systematic contribution to zero-emission mobility in this area.”

Glonner presented the innovative energy concept of the ARTHUR fuel cell bus to the participants, which has a hydrogen consumption of less than six kilograms per 100 kilometers. ARTHUR not only offers emission-free buses, but is also a system manufacturer and is pursuing ambitious goals.

“We also want to steadily expand further business areas within the ARTHUR Holding in the hydrogen sector, especially in zero-emission mobility, for example finding solutions for the infrastructure” Glonner said.

Competition Among Technologies

Dr. Michael Haberland, president of Mobil in Deutschland e.V., gave an outlook on e-fuels and the future of the combustion engine in Germany. He explained that with 48 million combustion engine vehicles in Germany, it would not be possible to operate them all electrically in the future, as the capacity for charging the battery at peak times would not be sufficient. Climate protection and climate-neutral mobility are also possible for combustion engines. For example, vehicles can easily be operated with e-fuels — or in the future with other fuels such as hydrogen. He pleaded for openness to technology: “We need competition among technologies.”

Green Methanol

Roland Gumpert, CEO of Gumpert Automobile GmbH, expressed his preference for the use of green methanol as the fuel of the future. The company developed the Gumpert Power Cell with a methanol fuel cell. In general, the Gumpert Power Cell can be used for all modes of transport, but the company’s focus is on trucks, as the transport and logistics industry urgently needs a solution here.

“The next project is a 40-ton truck that is to travel from Munich to Spain in one go without stopping, and not like a battery truck that would then need three days to recharge in Spain,” said Gumpert.

Gumpert Automobile GmbH aims to become a supplier to OEMs and is also working on product diversification. This would also solve the energy problem by using the waste heat from the Gumpert Power Cell to heat a house. Gumpert is convinced “that our technology will become a mainstream technology in the future, replacing much of other outdated technologies that pollute the environment and release emissions.”

In the discussion round, the experts agreed that hydrogen is needed for emission-free mobility. The mobility turnaround will not succeed with electromobility alone. Open technology is the order of the day. Different technologies would probably be used in parallel, depending on the purpose, mode of transport and distance to be covered. There was also agreement among the participants that the networking of the actors was important and that the discussion had to be continued. Only together can the mobility revolution succeed.

The Energy4Mobilty talk series will be continued this year. The next dates and further information are available here.
