A look back on the conference
After the 160 experts who travelled to the Arts et Métiers school in Châlons en Champagne in 2021, no fewer than 280 participants gathered at the PRISME laboratory in Orleans on 30 March for the second edition of this conference dedicated to hydrogen as a power source for internal combustion engines.
In addition to the increase in the number of participants, the special feature of this edition was the opportunity to discuss the first applications, with the presentation of three engines and two vehicles that have already accumulated test kilometres.
The participants, who arrived in Orleans the day before the event, had the opportunity to visit the PRISME laboratory, whose work is aimed at better understanding and modelling the behaviour of hydrogen in the very specific conditions of combustion chambers.
During the conference itself, presentations by representatives of research centres, equipment manufacturers and car manufacturers allowed us to measure the very rapid increase in the maturity of all the players.
What are the main lessons learned from these exchanges? There are many, but the most important is that the hydrogen internal combustion engine works, that it is very close to the fossil fuel engines currently in circulation, that it already achieves efficiencies close to those of diesel and that it does not emit CO2.
While these initial results are promising, a number of technical issues still need to be addressed before this technology can be mass-produced, which would allow a large proportion of the fleet to be decarbonised quickly and at lower cost.
It is also interesting to note that many players have been able to combine their efforts through consortia under the aegis of research institutes such as the PRISME laboratory.
Collaboration and speed therefore seem to be the key words in this field of application which, like the hydrogen molecule, is spreading at breakneck speed!
So, see you in 2024 for a third edition of this day?
