In this research, the impact of a carbon sequestration project, in the Hossein Abad Plain in Southern Khorasan Province of Iran, on the status of water and wind erosion was evaluated. The study area has a harsh climatic condition with low annual precipitation and is prone to well-known 120-day winds in summer. Since 2005, various soil conservation treatments (plantations, over-sowing, plantatio...

Seaweed has the ability to use carbon from the environment through photosynthesis to produce biomass. The aim of this study is to estimate carbon sequestration by seaweed aquaculture as a strategy for climate change mitigation. The study was undertaken at Gerupuk Bay, Lombok Island, West Nusa Tenggara Province, Indonesia. Four seaweed variants, such as Kappaphycus alvarezii var. Tambalang and M...

The reduction in CO2 emissions is very important, as highlighted by the issue of global climate warming. As a developing country, China has great differences in regional economic development, which makes it necessary to implement the ecological compensation of regional carbon emissions to coordinate the relationship between regional economic development and environmental protection. Using the e...

The vertical separation of organic matter formation from respiration can lead to net carbon sequestration within the ocean’s interior, making the biological pump an important component of the global carbon cycle. Understanding the response of the biological pump to the changing environment is a prerequisite to predicting future atmospheric carbon dioxide concentrations. Will the biological pump...

This report is being written for the Carbon Sequestration Initiative at the request of two members, GM and ChevronTexaco. The purpose is to give a brief overview and assessment of carbon sequestration by mineral carbonation (referred to as “mineral sequestration” in this report). The assessment is to highlight areas that need development in order for this technology to become commercial, not to...

Root system architecture (RSA) describes the dynamic spatial configuration of different types and ages of roots in a plant, which allows adaptation to different environments. Modifications in RSA enhance agronomic traits in crops and have been implicated in soil organic carbon content. Together, these fundamental properties of RSA contribute to the net carbon balance and overall sustainability ...

Check-dams are the most common structures for controlling soil erosion in the Loess Plateau. However, the effect of check-dams on carbon sequestration, along with sediment transport and deposition, has not been assessed over large areas. In this study, we evaluated the carbon sequestration function of check-dams in the Loess Plateau. The results indicate that there were approximately 11 000 che...

This research explores the feasibility of catalysis-based carbon sequestration by efficiently and accurately modeling the underlying chemical reactions and using this model to identify optimal operating conditions. We employ established and novel computational methods to calculate the Arrhenius rate constants required to model the chemical reactions as a coupled system of differential equations...

We develop a novel superstructure of algal biorefinery processes for biological carbon sequestration and utilization, encompassing off-gas purification, algae cultivation, harvesting and dewatering, lipid extraction, remnant treatment, biogas utilization, and algal oil upgrading stages. Based on the superstructure, we propose a mixed-integer nonlinear programming (MINLP) model to minimize the u...
