Modeling Carbon Sequestration in Home Lawns

Modeling Carbon Sequestration in Home Lawns

Soil organic carbon (SOC) sequestration and the impact of carbon (C) cycling in urban soils are themes of increasing interest. A model was developed to investigate the potential of C sequestration in home lawns. The model contrasted gross C sequestered versus the hidden C costs (HCC) associated with typical lawn maintenance practices. The potential of SOC sequestration for U.S. home lawns was d...

Pore-Level Modeling of Carbon Dioxide Sequestration in Brine Fields

Underground injection of gas is a common practice in the oil and gas industry. Injection into deep, brine-saturated formations is a commercially proven method of sequestering CO2 . However, it has long been known that displacement of a connate fluid by a less viscous fluid produces unstable displacement fronts with significant fingering. This fingering allows only a small fraction of the pore v...

Economic Modeling of Carbon Capture and Sequestration Technologies

As policy makers consider strategies to reduce greenhouse gas emissions, they need to understand the available options and the conditions under which these options become economically attractive. This paper explores the economics of carbon capture and sequestration technologies as applied to electric generating plants. The MIT Emissions Prediction and Policy Analysis (EPPA) model, a general equ...

Carbon sequestration in leaky reservoirs

We propose in this paper a model of optimal Carbon Capture and Storage in which the reservoir of sequestered carbon is leaky, and pollution eventually is released into the atmosphere. We formulate the social planner problem as an optimal control program and we describe the optimal consumption paths as a function of the initial conditions, the physical constants and the economical parameters. In...
