“…While the former is dominated by the heliostat fields, the latter is mainly determined by a combination of the power block, the heat exchangers and the intermediate storage of synthesis gas. These results are in line with other technoeconomic assessments as they show that the solar field is the largest contributor to the total capital investment [52,56,57].…”

Non-abatable emissions are one of the decarbonization challenges that could be addressed with carbon-neutral fuels. One promising production pathway is the direct air capture (DAC) of carbon dioxide, followed by a solar thermochemical cycle and liquid fuel synthesis. In this study, we explore different combinations of these technologies to produce methanol from an economic perspective in order to determine the most efficient one. For this purpose, a model is built and simulated in Aspen Plus®, and a solar field is designed and sized with HFLCAL®. The inherent dynamics of solar irradiation were considered with the meteorological data from Meteonorm® at the chosen location (Riyadh, Saudi Arabia). Four different integration strategies are assessed by determining the minimum selling price of methanol for each technology combination. These values were compared against a baseline with no synergies between the DAC and the solar fuels production. The results show that the most economical methanol is produced with a central low-temperature DAC unit that consumes the low-quality waste heat of the downstream process. Additionally, it is determined with a sensitivity analysis that the optimal annual production of methanol is 11.8 kt/y for a solar field with a design thermal output of 280 MW.

“…As already described, the thermochemical cycle requires heat delivered by CSTE and thus, the WS and CDS depend on sunlight availability. However, the production of methanol from hydrogen and carbon monoxide is operated around the clock for operability and economic reasons: on the one hand, daily shutdowns are avoided, and on the other hand, the flowrates and the equipment can be smaller while obtaining the same output [40]. Consequently, a storing unit for the gases is needed (TK-401).…”

Methanol is an example of a valuable chemical that can be produced from water and carbon dioxide through a chemical process that is fully powered by concentrated solar thermal energy and involves three steps: direct air capture (DAC), thermochemical splitting and methanol synthesis. In the present work, we consider the whole value chain from the harvesting of raw materials to the final product. We also identify synergies between the aforementioned steps and collect them in five possible scenarios aimed to reduce the specific energy consumption. To assess the scenarios, we combined data from low and high temperature DAC with an Aspen Plus® model of a plant that includes water and carbon dioxide splitting units via thermochemical cycles (TCC), CO/CO2 separation, storage and methanol synthesis. We paid special attention to the energy required for the generation of low oxygen partial pressures in the reduction step of the TCC, as well as the overall water consumption. Results show that suggested synergies, in particular, co-generation, are effective and can lead to solar-to-fuel efficiencies up to 10.2% (compared to the 8.8% baseline). In addition, we appoint vacuum as the most adequate strategy for obtaining low oxygen partial pressures.

“…Process simulation has been used in various research areas such as oil and gas, 26 chemical synthesis, 27,28 biomass utilization, 29,30 and renewable energy. [31][32][33] This approach was best exemplified in a feasibility study on solar steam methane reforming techniques, 31 in which emerging and established technologies were combined. The technical, economic, and environmental factors were evaluated for different combinations of volumetric receiver reactors, molten salts, solar thermal power generation, and water electrolysis capabilities.…”
