E-fuels are synthetically produced fuels and an alternative to fossil fuels in order to be able to continue to operate combustion engines in the future. In contrast to conventional fuels, electricity from renewable energy sources is used to produce e-fuels. However, the development of e-fuels is still in its infancy - electric motors are currently still significantly more efficient than combustion engines powered by e-fuels, although their range is still limited due to the battery capacities required.
Where could e-fuels be used?
At present, the possible uses of e-fuels revolve more around logistics and military applications than passenger transportation. The current limitations of electromobility also affect operational and combat vehicles (i.e. special vehicles for the military) of the German Armed Forces or other armies. In remote, actively contested regions of the world, there will be no charging infrastructure any time soon, and changing batteries is also utopian in this scenario. A sustainable, practical alternative without mineral oils is therefore needed here. The same applies to maritime units and aircraft. The combustion engine is almost fully developed, has been tested in all scenarios and is extremely stable. E-fuels are therefore a solution to ensure the future transport and combat readiness of military units and their vehicles.
The development in the area of BOS (authorities and organizations with security tasks) is likely to be exciting: As there is less continuous operation here and a charging infrastructure is easier to implement, the electrification of vehicle fleets is certainly within the realms of possibility in the coming years. E-fuels could be a solution for combustion engines, especially in the case of disaster vehicles at THW and the like. At Norrenbrock Technik, we have been closely monitoring the debate on alternative drive systems for years and are already offering innovative solutions for electromobility in special vehicle construction.
