Cummins generator fueled with hydrogen/biogas mix

By Cummins Inc. | June 06, 2013

In a significant scientific and environmental achievement, a combined team of engineers and technicians from Ad Astra Rocket Co. and Cummins Power Generation, a business unit of global power leader Cummins Inc., have successfully powered a Cummins-built electrical generator using mixtures of hydrogen and biogas.

The team's success goes hand-in-hand with a parallel and ongoing technology development to store hydrogen affordably—previous methods have been costly. The teams also designed a reliable process to mix and control hydrogen and biogas, and use together as an efficient energy source. These achievements could have long-term positive impacts especially in the developing world where energy resources are scarcer and less affordable.

"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 of 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 program."

"We are pleased to be part of this incredible achievement," said Tony Satterthwaite, president of Cummins Power Generation and vice president of Cummins Inc. "This is innovation at its finest and innovation is one of our company's core values. Further, at Cummins, part of our mission demands that everything we do creates a cleaner, healthier and safer environment and exploring, and investing in new and diverse fuel alternatives helps us meet that important mission."

The electrical generator designed and manufactured by Cummins is part of an experimental 7.5 kW renewable energy system being studied for potential commercialization by a combined team from Ad Astra Rocket Company, Cummins Inc. and EARTH University in Costa Rica.

Other components of this system include an Ad Astra designed solar and wind-based hydrogen production and storage system. Ad Astra is developing this system in collaboration with Costa Rica's state-owned oil refinery, RECOPE. In addition, biogas production from biodigestors is being studied by EARTH University.

Friday's commissioning tests are the result of careful preparation and safety reviews conducted by the engineering team. A full battery of experiments will follow to complete full system characterization and optimization. The Friday tests were conducted with hydrogen-propane mixtures in preparation for the first methane deliveries, which will follow the commissioning demonstration.

The collaborative project was initiated in July of 2011 as part of an integrated renewable energy concept being studied by Ad Astra with application to distributed power architectures and other derivative uses worldwide.
