Many studies have developed mathematical programming models for optimal design of supply chains for agricultural or lingocellulosic biomass-derived bioethanol production. However, because of the shortcomings of using agricultural (food supply problems) and lingo-cellulosic biomass (low biomass availability and processing yield) as feedstock, use of...

Most industries consume a large amount of energy to produce goods and to reduce the resultant CO2 emissions. We develop a systematic process integration framework for the optimal design and techno-economic performance analysis of energy supply and CO2 mitigation strategies. We first generate an Integrated Energy Supply and CO2 Mitigation Network (I...

Most chemical plants have their own utility systems (UtSys) to produce utilities (e.g., steam, electricity, water) required for manufacturing chemical products, and the UtSy discharges a considerable amount of flue gases. A monoethanolamine (MEA) based CO2 capture system (CCSy) is a promising solution to separate CO2 from the flue gases, but it can...

Recently increasing attention has been given to a hydrogen infrastructure (HI) including producing, transporting, and delivering H-2, the next generation alternative renewable energy source to users. This paper is concerned with designing the HI considering multiple perspectives of economic cost efficiency, safety and low CO2 emission simultaneousl...

In this study, a comprehensive infrastructure assessment model for carbon capture and storage (CiamCCS) is developed for (i) planning a carbon capture and storage (CCS) infrastructure that includes CO2 capture, utilization, sequestration and transportation technologies, and for (ii) integrating the major CCS assessment methods, i.e., techno-economi...

This study models a network that simultaneously disposes of CO2 and supplies H2. It is motivated by the inevitable reality that renewable energy sources cannot entirely replace fossil fuels at one time. Fossil fuels should be used for some time with renewables. Decision supporting tools to maximize the impact of integration must be developed. The p...

This paper proposes a design methodology for energy infrastructure to address the recent economic and environmental challenges. The proposed energy infrastructure was based on the recognition that fossil fuels will be used for some time with renewable energy sources because renewables are currently unable to replace fossil fuels entirely. A two-fol...

In this study, we address the design of a carbon capture and storage (CCS) infrastructure with economic and environmental concerns. Given a set of available technologies to capture, sequestrate, and transport CO2, the problem consists of determining the optimal planning of the CCS infrastructure capable of satisfying a predefined CO2 reduction targ...

A multiperiod stochastic programming model is developed for planning a carbon capture and storage (CCS) infrastructure including CO2 utilization and disposal in an uncertain environment and with a time-varying investment environment. An inexact two-stage stochastic programming approach is used to analyze the effect of possible uncertainties in prod...

To effectively reduce CO2, CO2 mitigation technologies should be employed tactically. This paper focuses on carbon capture and storage (CCS) as the most promising CO2 reduction technology and investigates how to establish CCS strategy suitably. We confirm a major part of the optimal strategy for CCS infrastructure planning through a literature revi...

A large number of research works were undertaken for the planning of sustainable electricity generation and CO2 mitigation (EGCM) infrastructure design under uncertainty. The typical methodologies assessed the performance of the problem under the variability of the uncertain parameters by optimizing the expected value of the objective function. Thi...

A carbon capture and storage (CCS) plays a very important role to reduce dramatically in emission sources which are distributed throughout various areas. Numerous research works have been undertaken to analyze the techno-economic feasibility of planning the CCS infrastructure. However, uncertainties such as emissions, reduction costs, and carbon ta...

Hydrogen draws increasing attention as an alternative energy source. In order to provide hydrogen to various sectors such as industry, transportation on a global scale, how to produce and distribute it economically is an essential issue not to be missed. This study thereby addresses mathematical modeling of hydrogen supply networks. The proposed mo...

It is difficult to clearly estimate CO2 emissions because CO2 is emitted from various sources according to changing environments. Any approach relating to CO2 disposal has to deal with the presence of such uncertainty in CO2 disposal demand. A two-stage stochastic programming model is developed for planning CO2 emissions disposal networks by taking...

Reducing CO2 emissions economically and efficiently necessitates the construction of carbon capture and storage (CCS) infrastructure as a comprehensive network that is capable of disposing of, and of utilizing CO2. Most of the early attempts to design and model the future CCS infrastructure were either limited to examining an individual component o...

Considerable attention has been given to carbon dioxide for its impact on climate change. Due to carbon dioxide being emitted from various chemical and petrochemical plants, the gases in geographically scattered places should be gathered, transported and sequestrated. The carbon dioxide disposal network resulting therefrom is a recently emerging is...

In a power-generation system, power plants as major CO2 sources may be widely separated, so they must be connected into a comprehensive network to manage both electricity and CO2 simultaneously and efficiently. In this study, a scalable infrastructure model is developed for planning electricity generation and CO2 mitigation (EGCM) strategies under...

Numerous research works have been undertaken to plan carbon capture and storage (CCS) infrastructures for CO2 utilization and disposal. CO2 emissions are difficult to estimate precisely, because CO2 is emitted from various sources at varying rates. In this study, a two-stage stochastic programming model is developed for planning CCS infrastructure...

Much of the previous research on carbon capture and storage (CCS) has focused on individual technologies for disposing of CO2, such as capture, storage, sequestration, or transport. Moreover, recent research work considers utilization of CO2 as fuels, chemicals, or nutrients for bioreactors. To efficiently manage CO2 and the economic benefits achie...
