No. 268: A new product for Carbon Dioxide Capture and Storage (April 25, 2011)

Carbon Dioxide Capture and Storage (CCS) is the technology to separate and store carbon dioxide emitted from manufacturing plants and power plants belowground. It is developing rapidly, and some estimate that more than 100 CCS facilities will be built in 2020 worldwide. Hitachi Zosen successfully developed the filtration equipment using thin films and plans to put it into practical use in 2012. The new product is expected to reduce the running cost by 20% from the existing method that requires special absorption agents and solution. It is a roll filtering machine, and inorganic material called zeolite is applied on its leachy ceramic surface. It is 115 cm long and 1.6 cm in diameter, and can separate 3 kg of carbon dioxide per day. It will cost about 30,000 yen. The customer can decided the number of rolls depending on its requirements. The company has already commercialized zeolite films and accumulated delivery results of the production facilities of plant-derived bioethanol. It modified the synthesis ratio of composition of zeolite including aluminum and silicone and elaborated the structure of crystal of the compound. CCS is expected to reduce 19% of 43 billion tons of carbon dioxide to be reduced by 2050 worldwide, and it is followed by utilization of natural energy, 17%, and utilization of nuclear power plants, 6%.
