CIDAUT, as an expert in the use of hydrogen and ammonia in propulsion systems, participates in the NEWBunker project, an initiative that aims to analyze the state of the art in marine propulsion systems with alternative fuels to conventional fuels, such as ammonia and hydrogen. The project will make it possible to identify the different supply modalities (bunkering) of these fuels depending on the storage system and the power generation system installed on board the ship.
NEWBunker is a project led by Gasnam with the technical management of Gas Natural Comercializadora (Naturgy group) and the participation of ESK, Fundación CIDAUT, TESICNOR, Siport21 and AEI-Basque Maritime Forum. This initiative has received a grant of aid for about 175,000 euros in the 2022 call for support for innovative business groups to improve the competitiveness of small and medium-sized companies.

Two new different diffusion actions have been carried out within VULKANO H2020 Project.
The first one was the assistance to the 9th European Combustion Meeting between 14th and 18th of April in Lisbon (Portugal). It was presented the poster entitled: “Natural Gas replacement by syngas in Resource Energy Intensive Industries (REII) burners: numerical CFD evaluation”. This poster gathered the theoretical study for the natural gas substitution by syngas as well as the burner modifications required to achieve the VULKANO objective of co-firing syngas from 10% to 40% of substitution. More than 180 posters in combustion topics were presented by 120 different authors speaking about topics such as: laminar flames, turbulent flames, reaction kinetics, gas turbines, etc.
The second one was the assistance to the 11th Mediterranean Combustion Symposium from 16th to 20th of June in Tenerife, Spain. There, the last part of VULKANO progress was presented in the paper entitled “CFD approach in natural gas hybrid burners adapted for syngas combustion in REII”. This paper goes one step further in the design of new hybrid burners to achieve 100% of natural gas substitution by renewable gases such as process-off-gases and bio-syngases. Both works have been carried out in close collaboration with the Institute of Power Engineering of Warsaw (Poland).

The third General Assembly Meeting of VULKANO project took place in Warsaw on 4-5th July 2018 in presence of the Project Technical Advisor of the European Commission. The meeting gathered more than 30 members of 11 companies located in 6 different countries, in order to review the general status of the project after the first twenty four months of execution.
The project has satisfactorily achieved its objectives throughout this time, obtaining useful results:
- Operating conditions of the two demo site furnaces (steel and ceramic sector) and the requirements from the new technology solutions to be implemented at the furnace have been defined.
- Development of Phase Change Materials (PCM) high temperature (up to 900ºC). After the simulations and the laboratory tests, the production of new PCM has started as well as it pre-implementation in ceramic furnace.
- Development of new refractories with the use of byproducts for the production of innovative materials. For steel furnace, materials based on alumina are used, while based on zirconia materials have been employed for the ceramic furnace.
- Feasibility of the natural gas substitution by the different syngas sources and Computational Fluid Dynamics (CFD) simulation of syngas/natural gas mixtures with adapted co-firing burners. Two different burners have been developed: dedicated burner for 100% of syngas combustion and hybrid burner for 0-100% of syngas / natural gas combustion.
- Optimization of the furnace monitoring and control system through metaheuristics algorithms and implementation. Steel case: automatization of gasifier&co-firing system. Ceramic case: control of PCM system.
- Presentation of a flexible holistic in-house predictive tool prioritizing the critical parameters for each sector with a video explicative.
- Start the construction of the replica furnace.
- Updated market analysis presentation.
With the results of the assessment, IEn as Task leader on WP5.2, 5.3 and 5.4, presented the co-firing CFD simulations, jointly undertaken by IEn and CIDAUT for the unmodified burners. It has been designed, simulated and experimentally tested two new burners: a hybrid one to operate between 0 to 100% of syngas substitution and a dedicated one to operate at 100% with syngas.
Furthermore, VULKANO project partners have already generated seven scientific publications and with an estimated number of 13 to 15 during 2019. CIDAUT has already presented one paper in ECOS Conference in Guimaraes entitled “Application of the CFD simulation to the evaluation of natural gas replacement by syngas in burners of the ceramic sector”.

ECOS 2018 is the 31st International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems which has been taken place in Guimarães between the 18th and the 21st of June.
Main topics discussed during the conference have been exergy as a process optimization, ORC, thermal recovery, fuel cells, energy storage, renewable energy, combustion, etc.
Under VULKANO Project CIDAUT’s paper entitled “Application of the CFD simulation to the evaluation of natural gas replacement by syngas in burners of the ceramic sector” has been presented.This paper gathers a wide evaluation of the alternatives in the reduction of fossil fuel consumption, such as natural gas, promoting its substitution by an alternative fuel (Co-firing). A revision of the types of syngas with potential for use has been carried out, as well as the evaluation of the physical properties of the mixtures from the combustion operation point of view. The feasibility study has taken into consideration parameters such as the low heat value, the Woobe index, adiabatic flame temperature, air preheating temperature, total flue flow and laminar flame velocity. The modifications for SG co-firing have been evaluated using CFD simulations to establish the proper design of the mix zone to ensure the mixture between the air, syngas and natural gas. Moreover, despite the initial objective was to replace 40% of natural gas energy by syngas in an industrial ceramic furnace, new dedicated burners for 100% of syngas substitution have been designed and simulated.
The Institute of Power Engineering (IEn), as partner of CIDAUT in VULKANO, also presented a paper entitled “CFD analysis of natural gas substitution by syngas in industrial furnaces” which evaluated the integration of new burners in the whole furnace system and simulating the real heating process in steel sector.
Furthermore, the VALORCOMP project partners have also been involved attending to different technical presentations in topics related with biomass, energy use and combustion, gasification, reaction engineering and CO2 mitigation.

As Task leader on WP5.1 “Designing and validating of co-firing systems”, CIDAUT presented to the Project Technical Advisor the results obtained in the feasibility assessment of natural gas substitution by alternative fuels (co-firing) in furnaces. Several syngas streams were considered from biomass gasification and process off-gases from steal sector.
With the results of the assessment, IEn as Task leader on WP5.2, presented the co-firing CFD simulations, jointly undertaken by IEn and CIDAUT for the unmodified burners. A deployment plan to design new adapted burners for an optimal co-firing was also established.
