Swoboda, Philipp; et al. (2021): Remineralizing soils? The agricultural usage of silicate rock powders: A review

Swoboda, Philipp; Döring, Thomas F.; Hamer, Martin (2021): Remineralizing soils? The agricultural usage of silicate rock powders: A review. In Science of the Total Environment, p. 150976. DOI: 10.1016/j.scitotenv.2021.150976.

„Soil nutrient depletion threatens global food security and has been seriously underestimated for potassium (K) and several micronutrients. This is particularly the case for highly weathered soils in tropical countries, where classical soluble fertilizers are often not affordable or not accessible. One way to replenish macro- and micronutrients are ground silicate rock powders (SRPs). Rock forming silicate minerals contain most nutrients essential for higher plants, yet slow and inconsistent weathering rates have restricted their use in the past. Recent findings, however, challenge past agronomic objections which insufficiently addressed the factorial complexity of the weathering process. This review therefore first presents a framework with the most relevant factors for the weathering of SRPs through which several outcomes of prior studies can be explained.“

Rosa, Lorenzo; et al. (2021): The Role Of Beccs To Deliver Negative CO2 Emissions In Europe

Rosa, Lorenzo; Sanchez, Daniel; Mazzotti, Marco (2021): The Role Of Beccs To Deliver Negative CO2 Emissions In Europe. In SINTEF Proceedings (7). Available online at https://sintef.brage.unit.no/sintef-xmlui/bitstream/handle/11250/2780214/THE%20ROLE%20OF%20BECCS%20TO%20DELIVER%20NEGATIVE%20CO2%20EMISSIONS%20IN%20EUROPE.pdf?sequence=1[&]isAllowed=y.

„Bio-Energy with Carbon Capture and Storage (BECCS) is a key climate mitigation technology, which involves the capture and permanent sequestration of biogenic carbon dioxide (CO2). To reach net-zero-CO2-emissions by 2050, it is forecasted that many million tons of CO2 will have to be sequestered through BECCS in Europe. There are different industrial processes that utilize biomass for bio-energy production, namely, pulp and paper mills, biogas facilities, incinerators, and biomass-fired power plants. Moreover, crop residues, organic food waste, and livestock manure could be utilized to transform biomass from a poor energy carrier to an efficient carbon drawdown carrier through BECCS. Here, we quantify the techno-environmental potential for biogenic carbon dioxide removal considering prospective BECCS opportunities that do not require purpose-grown bio-energy plantations. Combining process engineering with a bottom-up assessment, we find that there are 200 million tons CO2 yr-1 that could be deployed for biogenic carbon dioxide removal through BECCS in Europe.“

Wu, Zitao; Zhai, Haibo (2021): Consumptive life cycle water use of biomass-to-power plants with carbon capture and sequestration

Wu, Zitao; Zhai, Haibo (2021): Consumptive life cycle water use of biomass-to-power plants with carbon capture and sequestration. In Applied Energy 303, p. 117702. DOI: 10.1016/j.apenergy.2021.117702.

„Biomass-to-power conversion provides the most promising route to bioenergy with carbon capture and sequestration (BECCS). The objectives of this study are to estimate the water consumption of biomass-to-power plants with CCS and then quantify its variability and uncertainty on a life cycle basis. The fuel-based life cycle analysis reveals that compared to the case of complete coal combustion with CCS, co-firing biomass at coal-fired power plants with CCS significantly increases the life cycle blue water consumption, depending on the type, co-firing rate, and production location of biomass; and dedicated biomass combustion with CCS further increases the life cycle blue water consumption by a factor of more than 55.“

Wang, Nan; et al. (2021): What went wrong? Learning from three decades of carbon capture, utilization and sequestration (CCUS) pilot and demonstration projects

Wang, Nan; Akimoto, Keigo; Nemet, Gregory F. (2021): What went wrong? Learning from three decades of carbon capture, utilization and sequestration (CCUS) pilot and demonstration projects. In Energy Policy 158, p. 112546. DOI: 10.1016/j.enpol.2021.112546.

„The delivery of operational clean energy projects at scales is essential for addressing climate change. Carbon capture and sequestration (CCUS) is among the most important clean technology, however, most CCUS projects initiated in the past three decades have failed. This study statistically evaluates the reasons for this unfavourable outcome by estimating a hazard model for 263 CCUS projects undertaken between 1995 and 2018.“
