CO[sub 2] mitigation and energy production with microalgae

Three R D projects to mitigate CO[sub 2] by using microalgae are conducted. The objectives of each project are: (1) Maximum fixation of CO[sub 2] and high density cultivation by using optical fiber, (2) maximum production of energy and (3) hydrogen production. To increase the productivity of the biomass per area is one of the most important point for Japan, where no large area is available. The results of the experiments by Mitsubishi in cooperation with Japanese power companies are presented.
