The City of Yokohama, Tokyo Gas, Mitsubishi Heavy Industries (MHI) and MHI Environmental & Chemical Engineering (MHIEC) have launched a pioneering demonstration experiment geared toward capturing and using CO2 emissions from an area waste-to-energy plant.
The undertaking, primarily based in Tsurumi-ku, Yokohama, is the primary of its form in Japan and entails the separation and seize of CO2 from plant flue gasoline, which is then transported to a methanation facility for reuse. This novel strategy to carbon seize and utilization (CCU) additionally goals to introduce and increase using e-methane.
This groundbreaking initiative was agreed upon by Yokohama and Tokyo Gas in 2022, alongside MHI and MHIEC. With trial operations for all tools now full, the companions are launching the undertaking, which is able to make the most of MHI’s CO2 separation and seize system on the Tsurumi Plant.
The captured CO2 might be transported to the Tokyo Gas Yokohama Techno Station for use in methanation, marking a singular occasion in Japan the place CO2 from a waste-to-energy plant is moved to a distinct location for such use.
Moreover, the methanation facility being utilized for this demonstration operates on 100% renewable power, sourced from electrical energy generated at waste-to-energy vegetation in Yokohama.
In the longer term, the companions purpose to broaden using captured CO2 past methanation amenities. They additionally plan to implement measures for visualizing the CO2 worth chain, together with monitoring the quantity of CO2 collected and its transport vacation spot.
