Integrated Carbon Dioxide Scrubbing System for Shipboard CO2 Capture

CO2 emissions represent a significant threat to both the domestic security and national defense of the United States. Recently, the US Navy established a Climate Action 2030 plan, which targets aggressive reductions in CO2 emissions by 2030. A major limitation toward these reductions is the NavyÆs fleet. Despite recent technological advancements, the US naval fleet relies heavily on ships powered by gas turbine engines. Producing up to 7.5 lbs of CO2 per second at maximum power, these turbine engines represent a major contributor to naval CO2 emissions. However, technological and logistical considerations limit replacement of these engines in the immediate future. Accordingly, an intermediate solution would significantly benefit the NavyÆs climate mission. Specifically, the development of shipboard CO2 scrubbing systems would reduce emissions and facilitate the Navy in reaching its climate goals. This scrubbing system would also reduce emissions for the commercial shipping industry, substantially reducing overall contributions to global warming. To reduce CO2 emissions, Triton Systems, Inc proposes the development of an integrated scrubbing system for US Navy ships. This scrubbing system will utilize sorbent materials to remove CO2 from engine exhaust via chemical reaction. Utilization of regenerable sorbents provides minimum shipboard power consumption, produces no additional waste products or environmental pollution, and provides concentrated CO2 streams for use in chemical industry. Sorbents will be integrated with chemical process equipment to provide autonomous scrubbing with minimal maintenance and training requirements.
