Carnot – Heavy duty, little emission


Net-zero also works with heavy goods vehicles. Carnot ensures this with their engines - cost-effective, environment-friendly, low-emission.

„Our fuel agnostic design allows us to run on all net-zero fuels and together with our high efficiency gives us the lowest total cost of ownership in the market right now.“
Francis Lempp, Carnot

The larger the vehicle, the greater the environmental impact. In addition, this means a high energy demand and, conversely, increased costs - a major problem for companies in heavy duty. Carnot offers a solution for this with its engines, which makes the path to Net-Zero also possible for companies in the marine or off-highway sectors. Co-Founder Francis Lempp explains to us how exactly this is supposed to work - and where the Carnot Engines are used.

Who are you and what is Carnot Engines about in your opinion?
Carnot is tackling one of the toughest challenges of net-zero right now: Decarbonsing heavy duty markets by developing zero-emission combustion engines.

More and more public institutions but also companies are becoming aware of the pressure for sustainable energy. Where do you see the biggest blind spot in this respect?
Markets such as Marine, Heavy goods vehicles and off-highway are really tough to decarbonise and they have no production ready technologies to do so. Batteries and fuel cells aren’t applicable due to size, cost, and weight limitations so we need clean combustion solutions.

You say you produce the world's most efficient engines. What makes your products stand out from the rest?
Modern engines need cooling systems to prevent metallic components from melting and they waste huge amounts of energy (on average 30% of fuel). Carnot uses high temperature materials that can operate without cooling, eliminating this waste and bringing a step change in efficiency.
Our fuel agnostic design allows us to run on all net-zero fuels and together with our high efficiency gives us the lowest total cost of ownership in the market right now.

Where are your engines used in practice?
Heavy duty markets such as marine, heavy goods vehicles, off-highway machinery, and power generation. Anything from 100kW up to 8MW.

At the H2UB Sprint, experts with know-how are at your disposal. What steps do you want to take with their help?
Together with H2UB we devised a strategy to engage with end-users to get them to co-develop and fund our technology. We developed a plan that mitigates risk and we increase partners commitment which has allowed us to enter highly conservative and consolidated markets.

About the H2UB Sprint produced by BRYCK:  

It is a 10 week coaching program, that takes place twice a year. It is specifically designed to help start-ups accelerating their business by providing the right impulses, adapted to their needs. During the program the founder teams concentrate their efforts on selected core challenges, supported by group and 1:1 coaching sessions with dedicated business mentors of our partner BRYCK and hydrogen industry experts. The kick-off, interim and investor pitch presentations are organized as on-sites at our BRYCK tower in the heart of Essen, to enjoy the dynamical team spirit of the group, whereas most of the coaching sessions take place in a virtually workspace. The H2UB Sprint program is fully funded by H2UB, supported by its corporate partners and the state of North Rhine-Westphalia.
