🔎 The future cost of DACCS is a widely debated topic, with companies making claims they can get below $200/t, some even talking of $100/t. Market reports indicate significant demand uptake should these prices ever be reached.
📜 A study just published by Katrin Sievert, Tobias Schmidt, and Bjarne Steffen of the ETH Zürich and the Institute for Science, Technology and Policy, sheds light on the cost dynamics of DACCS pricing, challenging the feasibility of the <$200/t target.
📉 The authors use a new techno-economic method for projecting future costs of novel technologies which they apply to three DACCS technologies (combined with CO2 transport and storage) to provide probabilistic estimates of the future cost of net DACCS CO2 removal.
💵 At 1 Gt CO2/year cumulative capacity, the authors project costs of 230 to 540$/tCO2 across all three technologies: liquid solvent, solid sorbent, and CaO ambient weathering DACCS.
✈️ However, the authors note that DACCS still holds competitive potential for "hard-to-abate" sectors. For example, sustainable aviation fuels are projected to cost $245–$409/tCO2 by 2050, making DACCS a feasible alternative within the broader spectrum of emission reduction technologies.
💡 The takehome message for me is that DACCS will be a key part of the solution, offering a viable solution for specific hard-to-abaste emissions. It does also resonate that <$200 might never happen, unless we see unexpected major breakthroughs on energy and/or components. Other permanent CDR approaches will likely have the upper hand on price.
