Acacia Impact Innovation

Acacia Impact Innovation (acacia-ii.com) and HighTechXL (www.hightechxl.com) are, respectively, a Dutch company and a Dutch deep-tech accelerator program working jointly on a technological innovation to achieve large-scale removal of atmospheric methane. They are collaborating with Prof. Matthew Johnson of the University of Copenhagen to investigate a chlorine-based atmospheric methane removal technique using ship plumes as a distinct and attractive reactor class. The advantage of a plume-based approach is that it acts locally and within a limited time (hours), while it is still capable of entraining and processing large air volumes. Compared to other open-air methane removal approaches, they propose that plume-based reactors will be superior in having low environmental impacts that can be controlled, assessed and monitored, and can keep chlorine concentrations within safety limits, even close to the ship’s stack. CIEIF funding will allow the team to conduct expert impact modeling for a hypothetical field test and to obtain a detailed simulation of environmental impacts, as well as to initiate outreach to potentially-impacted stakeholders. The results will then inform them on whether actual field testing is desirable and feasible.
