Bridging experimental analysis to reservoir models: a geochemical modelling approach for Carbon Capture Storage

One of the techniques used to reduce CO2 emissions in atmosphere and minimize climate change's impacts on climate change is systematic modeling. In this context, numerical modeling can play a key role, particularly in the study of subsurface processes, geological, hydrogeological, meteorological, mineralogical, and geochemical studies must be integrated to determine, and possibly quantify, the effects of the dissolution-precipitation reactions triggered by CO2 removal and corresponding changes in the rocks' petrophysical properties. These models' limitations of overlooking mass migration are then overcome by running 1D cartesian simulations, which in turn were used to calibrate petrophysical parameters of more CPU-demanding 2D radial models set up for simulating CO2injection at a large scale, as well as their effects on lithology and petrophysical parameters. This last step represents the ideal link/bridge between experimental field and reservoir models in dynamic reservoir models. The ideal connection/bridge between experimental experimentation and reservoir models is shown in this last step.

Evaluating the efficacy of novel green fertilisers derived from combining carbon capture technology and organic waste materials

Mineral fertiliser production accounts for nearly 1% of the UK's greenhouse gas emissions. Organo-mineral fertilisers are now being tested as a more cost-effective alternative to conventional mineral fertilisers by combining mineral fertilisers with organic materials that would otherwise be destined for landfill or incineration, contributing to a circular economy by returning recycled nutrients to the soil, promoting a circular economy. Here, we analyzed the effectiveness of a novel OMF that incorporates carbon captured from gaseous point sources into their production. We conducted a field experiment using three batches of OMF and compared them to a conventional mineral fertiliser and unfertilised control in two soil types with two crops, but we found no significant or consistent difference between the fertilisers.

Analysing the viability of carbon capture and storage technology via SWOT/PESTLE analysis: Case study in Malaysia

Malaysia is one of the top energy-related CO 2 emitters among the South-East Asian countries, with the largest contribution coming from the energy sector. Carbon capture and storage technologies is one of the most promising methods to combat this anthropogenic greenhouse gases pollution. Whereas the introduction of CCS technology in Sarawak could attract foreign investment, increase economic growth, and job creation. In addition, the economic and economic benefits of retrofitting a CCS that can be retrofitted with existing power plants add value in terms of technology and economic value. Despite the worldwide expansion of CCS technology and its ability to reduce up to 52% of coal power plant emissions, this technology is likely to result in higher energy penalty and electricity decline, as well as lower plant efficiency, which can reduce both plant efficiency and profitability.

Significant land-sparing potentials from implementing carbon capture and utilization for the Brazilian sugarcane ethanol industry

Brazil is the world frontrunner in sugarcane ethanol production. Land use and cost are increasing, with sugarcane production moving to renewable electricity generation becoming a factor of increasing land use and costs. We develop a spatio-temporal model to determine the optimal system design, the resulting land use, and consequently the land sparing potential. Using ERA5 and ERA5-land reanalysis results, the optimization model depends on two time seriess that we derived specifically for each Brazilian ethanol plant based on a single time series of the CO2-streams from ethanol fermentation, as well as its second multi-year time series of wind and solar power in hourly temporal resolution using ERA5 and ERA5-land reanalysis results. In addition, the proposed pathway leads to a total increase of 43%-49% relative to the previous ethanol industry's current output in energetic terms. In comparison, an additional 23,000 km2 of land would be needed if the same amount of energy would be supplied by sugarcane ethanol, which is produced at the new average Brazilian sugarcane-to-ethanol land use efficiency.

Correlation comparison for prediction of density and viscosity of aqueous 2-(ethylamino)ethanol (EAE) for carbon capture

The most cost-effective method to capture carbon dioxide from a gas stream is aqueous amine solution for carbon dioxide removal from absorption techniques such as aqueous 2-ethanol. In addition, the absorption system's design, the density and viscosity are two primary characteristics. The aim of this research is to apply the existing correlations and to investigate correlation comparisons such as the Redlich-Kister equation, Wilson's model, and empirical polynomial correlation to predict these properties. Measurements are used to determine excess molar volumes and viscosity deviations, which are then correlated as a function of the mass fraction and temperature by using non-linear regression methods. The Redlich-Kister equation is the most valid model among these three correlations because it has the lowest average absolute deviation compared to the experimental findings, according to the study's findings.

Hydrothermal Carbonisation of Biomass Wastes as a Tool for Carbon Capture

One of the most promising directions for more environmentally friendly energy production is replacing fossil resources with bioresources, but a substantial amount of waste from biomass production and processing results in a significant amount of garbage with limited use and recycling options. The effect of biomass type and HTC conditions on the yield and stability of artificial humic substances and hydrochar to achieve carbon capture goals has been investigated in this research. Although hydrochar's carbon dioxide absorption capacity is relatively poor, after an activation effective sorbent can be obtained, the potential for carbon capture goals is unclear.

The status and prospects of materials for carbon capture technologies

Potassium hydroxide, a standard sorbent that reacts with CO 2 to convert it into K 2 CO 3 and then precipitates as CaCO 3. Solid sorbents are also functionalized with amines or have natural affinities for CO 2 in another class of carbon capture materials. Activated carbon, metal-organic frameworks, zeolites, carbon nanotubes, and ionic liquids are among the next generation of carbon capture materials under scrutiny. Other materials that can capture CO 2 from low concentrations of gas streams, such as air, are also discussed.

Ionic liquids for carbon capture

This article discusses cutting-edge research in ionic liquid-based materials and their effect on carbon capture. The absorption of CO 2 in ionic liquids can be achieved by physisorption or chemisorption, depending on the degree of the interaction. Both CO 2 -anion and cation-anion interactions, as well as physical contact, are important factors in determining CO 2 solubility. The ions' interaction with porous ionic liquids with porosity in Marrying lead to novel porous ionic liquids with unique characteristics for supporting gas transportation, while porous membranes allow the ions to seal the pores for selective gas transport. Future challenges include monitoring the interaction with CO 2 and its transport at the charged or electrified interface with the ionic-liquid electric double layer, as well as combining CO 2 capture and conversion with ionic fluids.
