Abstract Direct air capture (DAC) is a key component in the transition to net-zero society. However, its giga-tonne deployment faces daunting challenges terms of availability both financial resources and, most all, large quantities low-carbon energy. Within this context, small modular nuclear reactors (SMRs) might potentially facilitate DAC. In present study, we detailed thermodynamic analysis integrating an SMR with solid sorbent We propose different integration designs and find that coupling DAC significantly increases use thermal energy produced reactor: from 32% stand-alone 76%–85% SMR-DAC system. Moreover, 50–MW module equipped could remove around 0.3 MtCO 2 every year, while still producing electricity at 24%–42% rated power output. Performing techno-economic system, estimate net removal cost 250 €/tCO . When benchmarking it other supply solutions, system more cost-effective than powered by high-temperature heat pumps or dedicated geothermal systems. Finally, evaluate potential future China, Europe, India, South Africa USA, finding enable up 96 /year 2035 if SMRs prove be cost-competitive. The impact regional differences on also assessed.

Nuclear energy is increasingly being considered for such targeted applications as data centers in light of their high capacity factors and low carbon emissions. This paper focuses on assessing the tradeoffs between economies scale versus mass production to identify promising reactor sizes meet center demands. A framework then built using best cost estimates from literature ideal power needs given center. Results should not be taken deterministic but highlight variability output against required demand. While certain advocates claim that with gigawatts clean, firm needed, large plants are ideal, others advocate SMRs can deployed quantities reap benefits learning effects. The findings this study showcase identifying optimal size a likely more nuanced dependent application its requirements. Overall, does show potential economic promise coupling nuclear reactors industrial heat under key conditions assumptions.

Introduction There is a global goal to reduce greenhouse gas emissions by 43% 2023. Nuclear microreactors, subset of small modular reactors, offer potential solution due their compact size, transportability, and carbon-neutral power generation capabilities. Methods This study explores the feasibility using heat from nuclear microreactors for bioconversion agricultural processes, including transforming biomass into energy carriers products such as syngas, bio-oil, pasteurized milk. Operating requirements gasification, pyrolysis, hydrothermal carbonization, liquefaction, ethanol production, anaerobic digestion, pasteurization were obtained through literature review. A Brayton cycle model based on eVinci TM microreactor was developed assess powering these processes heat. Results Discussion Exergetic efficiency values high-temperature ranged 72% 100%, whereas lower-temperature 2% 53%. These efficiencies depend available source temperature each design. trade-offs between producing net process heat, particularly processes. Three exchanger locations considered: before turbine (600 ℃ ), regenerator (370 id="m2">℃ after (192 id="m3">℃ ). High-temperature like gasification require temperatures too high feasibility. Middle are better suited regenerator, while also operable turbine. Lower-temperature digestion can use waste do not impact production. findings valuable optimizing aligning with climate initiatives.
