Enabling Technology for Combustion and Carbon Capture with Alternative Fuels
Abstract
APPROVED FOR PUBLIC RELEASEProject Summary: The US Navy is investing significant resources to develop #e-fuels# from hydrogen obtained from seawater and captured carbon dioxide. The distributed production of fuel from local feedstocks can provide a logistical advantage while also supporting fleet decarbonization. Thus, the focus of this research is on developing the enabling technology for the use of these fuels in current and near-future Navy gas turbine systems. The specific goal is to demonstrate the combustion of and promotion of efficient onboard carbon capture from conventional and future #e-fuels# in a relevant gas turbine environment at the 100 kWth scale. The technical approach to achieve this goal is to investigate the use of exhaust gas recirculation and the impact on turbine operability to promote higher carbon dioxide exhaust concentration, which reduces the energy penalty of onboard carbon capture. The research goal will be accomplished through five research objectives (1) investigation of gas turbine operability with conventional and future fuel and approaches to generate high carbon exhaust concentration, (2) development of gas turbine operability prediction tool for exhaust gas recirculation and fuel flexibility, (3) identification of onboard carbon capture system parameters and architecture to minimize size, weight and power, and facilitate ship integration, (4) demonstration of integration of carbon capture and combustion system with conventional and future fuels, and (5) training of future naval workface. The primary outcome of this research will be the development and validation of operability and performance tools that will guide deployment of future fuels and onboard carbon capture on Navy ships. This will directly advance Navy interests for decongested logistics and decarbonization of the fleet. Secondary outcomes will be the establishment and demonstration of lab-scale carbon capture and turbine operability testing thatcan be used with numerous future fuel candidates, identification of operational parameters for larger scale testing at partner sites, and training of future Navy workforce in relevant technologies.
