Cummins and Ad Astra Rocket Company have successfully powered a Cummins generator with hydrogen and biogas.
Accomplishment of the project involved finding a reliable process of mixing and controlling hydrogen with biogas to use together as an energy source.
"This is a tremendous achievement in terms of the science and engineering as well as the environmental benefits associated with the use of hydrogen and biogas," said Franklin Chang Díaz, CEO, Ad Astra. "The teams from Ad Astra, Cummins and EARTH University came together and used their combined talents and creativity to achieve this key milestone. I am looking forward to the next phase of this programme."
The electrical generator forms part of an experimental 7.5 kW renewable energy system that is part of a comercialisation research project between Ad Astra Rocket Company, Cummins Inc. and EARTH University in Costa Rica.
The system also includes an Ad Astra designed solar and wind-based hydrogen production and storage system, which is being developed in collaboration with Costa Rican oil refinery, RECOPE.
The commissioning tests were carried out with hydrogen-propane mixtures in preparation for the first methane deliveries, which will follow the commissioning demonstration.
