“…The performance of the Selexol process to capture CO 2 from the HTL gas has been studied in more detail in a previous publication. 10 Based on the literature review conducted, the hydrocarbon impurities present in the CO 2 are not known to be contaminants for the methanol synthesis catalyst (Cu/ZnO/Al 2 O 3 ), and overall, the final composition seems to be in line with the purity recommendations suggested in the CCS literature (Table 7). Thus, further purification is deemed unnecessary within the scope of the present analysis.…”

“…The main impurities present in the CO 2 output stream are methane and C 2–4 hydrocarbons, predominantly ethane (1 mol %), propane (0.4 mol %), and butane (0.2 mol %), which is explained by their relatively high affinity for the solvent as compared to H 2 and CO.

“…State-of-the-art literature on HTL estimates overall energy efficiencies around 75%, with minimum selling price of drop-in fuels (MFSP) in the range of 15 to 40 EUR/GJ based on lignocellulosic biomass. − Alongside drop-in fuel production, the HTL process delivers a pressurized gaseous byproduct rich in CO 2 that holds potential for a cost-effective CO 2 purification and further conversion into e-fuels (BECCU), or further liquefaction for underground storage to yield negative emissions (BECCS). Still, based on the literature review conducted, the HTL-BECCU/S concept has remained largely unexplored with only few refs – .…”

This study examines the combined production of drop-in fuels and methanol using hydrothermal liquefaction (HTL) as a technological basis in the context of bioenergy and power-to-X (PtX) applications. Given the increasing need for flexibility in a system dominated by fluctuating renewable power, we evaluated flexible methanol operation as a strategy to harness global greenhouse gas (GHG) emissions in a grid-connected HTL setup. In this operation, the biogenic CO 2 destination is alternated between methanol synthesis bioenergy with carbon capture and utilization and combined underground storage depending on the hourly electricity price and grid carbon intensity. The results indicate that the strategy has potential to maintain the average fuel carbon intensity within the 65% GHG reduction threshold set by the renewable energy directive III at a minimum methanol price of 870 EUR/t. This approach could facilitate implementation as it does not require dedicated renewable power generation and hydrogen storage, potentially decreasing costs compared to semi-islands and off-grid PtX systems.

“…Furthermore, The HTL process with CCS is shown to be capable of reducing greenhouse gas emissions by 102–113% compared with fossil fuels 144 . Simulations using HTL, based on lignocellulosic biomass waste and urban biomass using Selexol™, indicate that CO 2 purity between 90 and 98 mol% can be obtained for 40–53 EUR t −1 and 98–99 mol% purity is achievable for 57–77 EUR t −1 145 . Although the liquefaction process is still being studied at the lab scale, further research and development are required to make it feasible for commercial use, as it can be an invaluable component of the BECCS process that produces liquid fuel and reduces CO 2 emissions.…”

The demand for sustainable energy sources has increased owing to environmental concerns, such as climate change, rising energy demand and rapid industrialization. Biomass utilization for bioenergy and value‐added chemical production has become essential for creating a circular low‐carbon bioeconomy and sustainable waste management techniques. This review focuses on thermochemical processes and analyzes the trends of biomass utilization for energy production in the EU over the last decade. It discusses the current state‐of‐the‐art of gasification, pyrolysis, advanced combustion and liquefaction technologies, and presents the individual challenges and prospects of each process. A comprehensive overview of previous studies related to each conversion technology is provided to pave the way for future thermochemical, biochemical and integrated biomass valorization studies. Additionally, the review discusses biomass thermochemical conversion processes, which are combined with carbon capture, such as gasification, liquefaction and pyrolysis. These processes offer the potential to achieve negative net atmospheric carbon emissions, which can contribute to global warming mitigation efforts.

The conversion of abundant forest- and agricultural-residue-based lignocellulosic materials into high-quality bio-oil by the mild hydrothermal method has great potential in the field of biomass utilization. Some excellent research on biomass hydrothermal process has been completed, including temperature, time, catalyst addition, etc. Meanwhile, some research related to the biomass raw material tissue structure has been illustrated by adopting mode components (cellulose, hemicellulose, lignin, protein, lipid, etc.) or their mixtures. The interesting fact is that although some real lignocellulose has approximate composition, their hydrothermal products and distributions show individual differences, which means the interaction within biomass raw material components tremendously affected the reaction pathway. Unfortunately, to our knowledge, there is no review article with a specific focus on the effects of raw materials and their tissue structure on the lignocellulose hydrothermal process. In this review, research progress on the effects of model and mixed cellulose/hemicellulose/lignin effects on hydrothermal products is initially summarized. Additionally, the real lignocellulosic raw materials structure effects during the thermal process are summed up. This article will inspire researchers to focus more attention on wood fiber biomass conversion into liquid fuels or high-value-added chemicals, as well as promote the development of world energy change.
