The abstract of a lunch lecture giving at Differ (www.differ.nl) about using Olivine for CO2 sequestration. Special attention is given to the Gravity Pressure Vessel to enhance the reaction kinetics.
Presentation at the 8th Dutch CCUS conference.
Short explanation of the idea of using Olivine as a feedstock (together with CO2) in order to produce "CO2 negative materials".
This document discusses using biotechnological processes to increase rates of silicate weathering and limestone formation to store carbon dioxide from the atmosphere. It proposes a two-stage anaerobic digestion system where acidogenic bacteria convert organic matter into carbon dioxide in one stage, and methanogenic archaea convert the carbon dioxide into methane in a second stage. The carbon dioxide is also used to form carbonate minerals like limestone for long term carbon storage. The document outlines using the residues from this process to produce biogenic cement for re-use in construction and agriculture.
The document discusses using olivine minerals to sequester carbon dioxide (CO2) from the atmosphere as a means of mitigating climate change. It describes how olivine weathers in the presence of CO2 and water to form magnesium carbonate and silica, permanently storing the carbon. Several companies are working on mineral carbon sequestration projects using olivine residues, mine tailings, or accelerating natural weathering processes. One such company, Green Minerals, sells a product called "greensand" for use in landscaping, sports fields, and construction to sequester CO2 while providing new markets for olivine materials.
The document discusses using olivine to reduce CO2 levels in the atmosphere through carbon mineralization. Olivine naturally reacts with CO2 and water to form magnesium carbonate and silica. Accelerating this process through mining, crushing, and spreading olivine could provide an effective method to lower CO2 levels. The company greenSand develops olivine-based products for use in soils and gardens to capture CO2 from the air on a large scale through natural carbonization processes. Modeling shows olivine sand can sequester 200-400 kg of CO2 per ton applied, providing an elegant and low-cost solution to climate change.

This document summarizes a presentation on modeling the weathering of olivine rock to sequester carbon dioxide from the atmosphere. The presentation models how olivine weathers over time, calculating the rate of CO2 sequestration and release of nickel into the environment. The model shows that for agricultural applications, only very fine olivine exceeds nickel regulations in the first month, but olivine can be used for both civil and agricultural uses overall. The document includes figures showing model inputs, outputs for CO2 sequestered, magnesium and nickel released over time, and nickel concentrations in plants and soils.
This document summarizes a workshop on mineralization held in Utrecht on September 2, 2019. It discusses using mineralization to sequester carbon dioxide through reactions with minerals like olivine. Specifically, it discusses using olivine in applications to replace agricultural lime and fertilizers. Modeling results are presented on carbon sequestration rates using olivine sand under different pH conditions. Companies active in mineralization technologies are listed, and examples of green sand sales and demonstration project certificates are presented. Developments in research networks and international projects are also summarized.
This document summarizes a presentation on green minerals and SCW systems given on June 25th, 2019 in Aachen. It discusses mineralization from an academic interest to commercial realization. It provides background on CO2 utilization and negative CO2 emissions approaches, including ambient and accelerated mineralization techniques. It also outlines several companies working in residual ores, ambient, and accelerated mineralization areas and describes Green Minerals' research on scaling up an olivine weathering process called GreenSand to store CO2.
This document summarizes a conference on mineralization of CO2 and its beneficial uses. It discusses using mineralization to permanently sequester CO2 by accelerating natural weathering processes. Methods presented include using industrial waste materials like steel slag and fly ash, as well as minerals like olivine and serpentine. Accelerated mineralization techniques aim to increase reaction rates through adding chemicals, operating at high pressure and temperature, or producing functional filler materials. Validation efforts include concrete and paper applications to replace cement or pulp to store CO2 long-term. Challenges addressed developing profitable processes, validating storage, and gaining market acceptance for new products.
The presentation discusses turning CO2 into valuable products by mineralizing it through reaction with olivine to form magnesite and silica. This process traps the CO2 while producing materials that can replace limestone and talc in concrete, paper, and polymers. Currently the process is being researched by Green Minerals and other partners to commercialize CO2 mineralization and utilize the products in various markets.
The document discusses turning carbon dioxide (CO2) into valuable products through mineralization. It describes trapping CO2 by reacting it with olivine at high temperatures and pressures to form solid carbonates. This process can be used to produce construction materials like concrete and paper coatings as a replacement for lime and talc, storing the CO2 within the final products. Some challenges to scaling this up include developing supercritical water systems for the reaction, performing validation testing on the beneficial use of products, and gaining market acceptance and policy support.

The document summarizes a presentation given at the International Conference on Negative CO2 emissions in Stockholm, Sweden on May 22, 2018. The presentation was titled "Safely & Economic Sequestering CO2 with Olivine" and discussed using the mineral olivine to safely and economically sequester carbon dioxide through an exothermic mineralization reaction. Test results from agricultural studies in Wageningen, Antwerp, and the Netherlands demonstrated olivine's ability to sequester CO2 from the atmosphere and sales data and pricing for olivine-based products were presented.
This presentation discusses using CO2 as a feedstock by mineralizing it through reactions with olivine. The process could help address climate change by providing permanent storage of CO2 emissions in minerals. While mineralization occurs slowly through natural weathering, the presentation describes approaches to intensify the reaction through milling, acids, or high pressure and heat in a reactor. Initial testing of the reactor process shows potential to mineralize CO2 while generating heat, and the resulting products may be used in concrete, paper, or polymers. Further research and scaling up of the mineralization technology is needed, but it offers circular economy benefits by converting the waste product of CO2 into useful materials.
This document summarizes a presentation given on March 13, 2018 in Newcastle, Australia about carbon dioxide (CO2) mineralization. The presentation discussed the past, present, and future of CO2 mineralization. In the past, academic and industrial projects explored using CO2 mineralization but were not economically feasible. Currently, the CO2MIN project is investigating CO2 mineralization through funding from the German government. Other current projects are setting up autoclaves and validating uses of mineralized CO2 in polymers and paper manufacturing. Future plans include participating in the CO2MIN project and developing continuous CO2 mineralization processes.
