Beskrivning
In light of ever accelerating climate change, series of mitigation options have entered the political debate. Among them: carbon dioxide removal (CDR) and in particular Direct Air Carbon Capture and Storage in basalt (DACCS-b), where CO2 is taken from the air, dissolved in water, and then pumped into underground basalt formations. According to theory, CO2 reacts with the rock and turns into carbonate minerals and - a central assumption of this approach - stays in this mineralized form forever. The notion of permanence is why DACCS-b is presented as the gold standard of CDR. However, there remains questions amongst scientists on whether mineralization does indeed take place to the extent and over the timescales needed for the technology to be safe and scalable. This matters greatly, because DACCS-b is currently a central tool in many climate mitigation strategies. Through this interdisciplinary research project at the frontier between the social science of climate mitigation and engineering geology, we aim to integrate the risks and uncertainties surrounding geological carbon storage more closely within sociopolitical assessments of DACCS-b. Given the intrinsic uncertainty of our knowledge on subsurface, invisible, phenomena, it is essential to define collectively what level of uncertainty is acceptable for a technology to be considered “safe” and “desirable”. By constructive interaction between scientists who help develop the technologies (engineers and to some extent natural scientists) and others who reflect on their practical effects (social sciences and humanities), we hope to lift the debate on whether engineering solutions to climate change are feasible and desirable pathways forward.
