We proudly present our new project on Recursive Sequential Combustion development: MOeBIUS.H ! This is a joint forces project between Combustion Bay One e.U. and Graz University of Technology / Institute of Turbomachinery and Machine Dynamics.
The major milestones of this 3-years project are:
- Progress in fuel placement and optimum mixing with fresh air and burnt gases. The study of hydrogen mixedness in this context will be studied in the frame of a PhD thesis
- Constant section combustor: an ultra compact combustor with a breakthrough architecture will be tested in the frame of this study

2024 was an exceptional year for industry services and R&D at CBOne. We are very happy to conclude the year with the publication of a European Patent, coming from the project we conducted from 2021 to 2023 called Bluetifuel. This is about the safe and low-NOx combustion of hydrogen. In this fifth patent of our IP portfolio, P&P Industries GmbH owns the patent and will see that the technology is deployed, e.g. in the fields of process engineering and energy. CBOne is the inventor.

Paper 157: Experimental Validation of a Recursive Sequential Combustor and Study of the Model
Sequential recursive combustion is a proprietary CBOne technology that we have been working on since the early 2020s. Recently, thanks to an approach that makes good use of additive manufacturing methods, we have been able for the first time to achieve sequential recursive combustion using multiple burners arranged in a loop. The results in terms of good emission performance and lean flame robustness are there for all to see.

IRON LIQORNE: C'est parti!
LIQORNE was a project to develop technologies for advanced thermal management of liquid hydrogen for aviation applications. Following the pilot project's success, CBOne is passing the baton to the FH Joanneum / Aviation team, who will lead this new phase, called IRON LIQORNE, towards creating an iron bird demonstrator.

Towards desirable H2 machines
... that are simply better than the state of the art with conventional fuels. This is within reach.
CBOne is offering for internships to work on technical subjects relating to hydrogen, with recruitment opportunities by 2025. Are you a mechanical or process engineering student? Are you interested in fluid mechanics, energy and gas turbines? We'd like to hear from you.
The subject covers the following topics:
- Design of a burner capable of operating at 100% with hydrogen in premixed mode, towards stoichiometry close to one
- The safety of using hydrogen, particularly with regard to the risk of detonation
- Thermal management and transitions of hydrogen as a working fluid, from the cryogenic state to the gaseous state in the positive temperature range. Use of hydrogen's high calorific value as a coolant.
- Design of thermal machines capable of operating with moderately hot gases (around 1000°C), using hydrogen highly diluted in air, where the lack of thermal efficiency is offset by the simplicity of cooling, if any.
- Improving the combustion performance of conventional fuels by adding hydrogen: thermal performance, emissions performance (NOx, CO, soot, unburnt fuel), stability performance (passivation of combustion instabilities), combustion range performance (towards ultra-lean regimes).
