Fuel Cell and Heat Engine Hybrid CHP Systems 
January 26-27, 2017
Washington, D.C. 

ARPA-E held a workshop on “Fuel Cell and Heat Engine Hybrid CHP Systems” on January 26-27, 2017 in the Washington, D.C. area. The workshop convened leading experts in fuel cells, heat engines, materials and advanced manufacturing technologies to identify related technological solutions that would help to enable the introduction of highly efficient (>70%) yet cost-effective (<$1800/kWe installed) commercial-scale combined heat and power systems.  

ARPA-E is interested in hybrid fuel cell and heat engine hybrid systems that have the potential to reduce the primary fuel consumption associated with the generation of electric power and the satisfaction of concurrent thermal loads (e.g. space or water heating).  Areas of interest and targeted outcomes include:

• Identification of synergistic integration approaches,

• Identification of critical heat-engine-integratable fuel cell stack design requirements,

• Identification of manufacturing approaches that have the potential to enable the fuel cell stacks to meet the cost target required for wide-spread commercial success,

• Identification of manufacturing approaches that have the potential to enable the heat engines, particularly microturbines and stirling engines, to meet the cost target required for wide-spread commercial success,

• Identification of the major technical risks to a successful commercial product, and

• Identification of potential spin-off applications.
