Patent EP4471330 A1: CBOne invents... the rapid premixer!
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.

A BLUETIFUEL ENDING
The picture shows what a flame of highly premixed hydrogen with air looks like in a high-performance industrial burner.
We demonstrated a two-stage burner fired with highly premixed hydrogen-air that produced combustion gases of over 1000°C with a NOx output of less than 15ppm, which is outstanding. The thermal power was one megawatt and was maintained over an extended time, with the burner demonstrating a high level of safety during start-up and shut-down and excellent stability during operation. The acoustic excitation with the Siren E from Combustion Bay One e.U. did not cause any combustion instabilities. The burner is therefore safe to use and has a high degree of industrial maturity.
The BLUETIFUEL pilot programme for the combustion of carbon-free biofuels was completed last week at the Erzberg open-sky iron ore mine. These industrial-scale tests were operated by P&P Industries AG.
We would like to take this opportunity to thank the management of P&P Industries AG, for supporting us in this latest experiment, which was carried out outside the project’s regulatory timeframe.
We would also like to thank Voestalpine Erzberg GmbH who made these tests possible by making the site available to us during November, the Austrian Research Promotion Agency FFG Österreichische Forschungsförderungsgesellschaft mbHand the Climate and Energy Fund for their financial support of the BLUETIFUEL programme (contract 881129), and last but not least our colleagues from FH JOANNEUM who were scientific partners in this project.
