Introduction

The gas mixer utilizes and mixes the fuels generated with the electrolyzer (hydrogen), gasification (syngas), and AD-BES unit (biomethane). The generated gas mixes are prepared to be used in the novel CHP unit of Aurelia – please refer to Section ‘Gas turbine (Aurelia)’ for more information regarding the specific gas mixes used in the CHP unit. The mixed gas fuels must therefore respect the gas mixtures and requirements of the CHP unit. The Paul Scherrer Institute (PSI) developed a tool to determine the characteristics of these fuel mixtures.

Technical description

A gas mixer blends hydrogen, syngas, and biomethane produced by the electrolyzer, gasification, and AD-BES, respectively. As the gas mixes are properly blended, they are ready for use in Aurelia's innovative CHP unit (Section), where the mixtures must meet the CHP unit's gas requirements.

The figure shows the tri-plot results of iso-hydrogen-concentration and iso-Wobbeinindex overwriting the source percent volumetric gas mixer inlet flow. This study enables the creation and delivery of excellent combusting fuels to CHP.
