"Hydrogen is a promising energy carrier of the future that can be produced in various ways, which must increasingly meet sustainability criteria."

Dr. Manuel C. Schaloske, e-mobil BW
"A new study by e-mobil BW analyzes the pros and cons of hydrogen combustion engines (H2 engine) and fuel cells (H2 FC) in heavy-duty transport. The comparison shows that both technologies have potential for long-haul transport; in the medium term, there is a tendency toward the use of H2 fuel cells."

Dr. Daniel Chatterjee, Rolls-Royce Power Systems
"Hydrogen is an essential element of the climate transition, but also a complex overall system. The presentation provides an overview of the global and local perspective of Rolls-Royce Power Systems."

Dr. Georg Töpfer, Deutz
"In the off-highway market, there is a very good opportunity to establish a hydrogen engine as a CO₂-free propulsion system, with the first series application planned for 2024. A demonstrator project is already underway. New challenges are expected in the hydrogen supply of machinery; DEUTZ is working with new partners to develop solutions."

Lukas Kniestedt, WTZ
"At WTZ Roßlau, it is possible to simulate and evaluate the interaction of various energy systems. The proprietary Argon Power Cycle represents a key technology for these energy cells and the energy transition."

Georg Blesinger, KIT
"Hydrogen is an indispensable element in the defossilization of large infrastructure facilities."

Tobias Michler & Dr. Olaf Toedter, IFKM KIT
"The required ignition energies and voltages necessitate a careful design of the ignition system."

"Hydrogen and biogas fueled combustion engines – Advances in spark ignition and current research."

Holger Kauß, Robert Bosch GmbH
"Besides the challenge of homogenization, transient torque build-up is another key success factor for the H2 engine – with various strategies, including direct injection playing a central role – significant potential can be unlocked here."

Bernd Niethammer & Christian Mayer, ITAZ
"The pre-controlled H2-ITAZ injector offers maximum flexibility with regard to the gases to be injected and the desired combustion processes, combined with an ultra-compact design, and can thus be used for a wide range of applications with almost no modifications."

Professor Dr. Thomas Jordan, KIT
"In the medium to long term, liquid hydrogen will be an economically attractive, carbon-free, and safe fuel due to its potential efficiency advantages across the entire conversion chain – especially for energy-intensive mobility or transport applications."

Bernhard Klipfel, BKES
"EGR is practically an indispensable requirement in order to take advantage of the hydrogen engine; however, starting from the well-known EGR technology, extensive adaptation and optimization are necessary."

Dr. Patrick Lott, KIT
"This presentation highlights the key aspects of hydrogen engine exhaust gas aftertreatment and particularly shows the state of the art, perspectives, and challenges related to selective catalytic reduction using ammonia as well as hydrogen."

Enno Eßer, TU Bergakademie Freiberg
"Catalytic NOx reduction using hydrogen offers a great opportunity to reduce the already low NOx emissions of the hydrogen combustion engine to or below the detection limit without using additional reagents."

Dr. Heiko Kubach, Dr. Uwe Wagner & Dr. Sören Bernhardt, KIT
"The hydrogen engine offers the potential for excellent efficiencies and increased specific power output with ultra-low emissions using 'well-known measures'."
