“…Note, that some predictions for the future development of DAC technologies calculate CO 2 cost of 150 to 200 € per ton by 2030. 37,38 A sensitivity study covering the low and high feedstock CO 2 and N 2 cost influence on the cost of H 2 delivery using vector X is provided in Fig. S3d in the ESI †.…”

“…While Carbon Engineering, the major technology vendor of HT-DAC, projects future capture costs of 94–170 € per t, Climeworks, one prominent LT-DAC supplier, projects costs of around 100 € per t. 33,34,36 Other studies predict CO 2 costs of 150 to 200 € per ton by 2030. 37,38 Whether this significant cost reduction will become reality in utility-scale operational plants has to be evaluated after first commercial plants have been commissioned.…”

“…The other economic parameters 8 used in this work are reported in table 3. The capital and non-energy operating costs of DAC are taken from [22] 9 . For the integration cost, which is added to the capital cost of DAC in all the cases considered, a value of 100 €/MtCO 2 /year is assumed.…”

“…On the other hand, while the cost of integration does not play a relevant role in the economics of the system, the CAPEX of DAC has a major impact on the NRC. Given that solid-sorbent DAC is not a mature technology yet, its cost estimations present significant uncertainties (±50% for the data used in this work [22]) and the NRC values obtained in this work should be interpreted accordingly. For example, a reduction in the CAPEX of 50% brings the NRC from 247 €/tCO 2 to 153 €/tCO 2 ; a similar sharp increase in the NRC is observed for a CAPEX increase of 50%.…”

Direct Air Capture (DAC) is a key component in the transition to net-zero society. However, its giga-ton deployment faces daunting challenges in terms of availability of both financial resources and, most of all, large quantities of low-carbon energy. Within this context, small modular nuclear reactors (SMRs) might potentially facilitate the deployment of DAC.In the present study, we present a detailed thermodynamic analysis of integrating an SMR with solid sorbent DAC. We propose different integration designs and find that coupling the SMR with DAC significantly increases the use of thermal energy produced in the nuclear reactor: from 32% in a stand-alone SMR to 76-85% in the SMR-DAC system. Moreover, we find that a 50-MW SMR module equipped with DAC could remove around 0.3 MtCO2 every year, while still producing electricity at 24-42% of the rated power output.Furthermore, we performed a techno-economic analysis of the system, finding a net removal cost of around 250 €/tCO2 When benchmarking it to other low-carbon energy supply solutions, we found that the SMR-DAC system is potentially more cost-effective than a DAC powered by high-temperature heat pumps or dedicated geothermal systems. When DAC is integrated with waste heat from a geothermal power plant, the SMR-DAC would be likely more expensive. However, the SMR-DAC system would circumvent the limitation given by the availability of geothermal waste heat at a sufficiently high temperature.Finally, we evaluated the potential of future deployment of SMR-DAC in China, Europe, India, South Africa and the USA, finding that it could enable up to 96 MtCO2/year by 2035, which is in line with the global requirements illustrated in the Net Zero by 2050 scenario of the IEA. The impact of regional differences on the removal cost was also assessed.

“…They state that USD10-15M was required to build the Orca plant (with removal capacity of 4,000 tCO 2 /yr) 18 and USD3-4M for building the Hinwil plant (with removal capacity of 900 tCO 2 /yr). 18 In addition, independent academic assessments and breakdown of the capital costs are beginning to be published from IEAGHG 10 , Young et al 105 , Sendi et al 106 , Valentine et al 107 . There are still significant uncertainties, especially with respect to the air contactor cost, as completely novel designs are required.…”

Direct air carbon capture and storage (DACCS) involves a set of approaches for capturing CO2 directly from the air and its subsequent long-term storage. DACCS is at an early stage of technical development and currently faces a variety of challenges, including high cost and energy requirements. Building on publicly available data, this paper provides: (i) an overview and classification of DACCS systems, (ii) a harmonization of technical and economic performance of direct air capture technologies, (iii) a comprehensive list of technical- and infrastructure-based obstacles to scaling DACCS systems, and (iv) a roadmap and list of priority initiatives for research, development, demonstration, and deployment of DACCS. Our intent is to drive progress against high-impact priority actions, with a focus on accelerating research, development, and deployment of safe, scalable, and low cost DACCS as a component of the broader carbon dioxide removal portfolio.
