Optimising Turnaround Maintenance (TAM) Scheduling of Gas plants in Libya
Gas plants consist of several pieces of both critical static and rotating equipment, which operate continuously under severe operating conditions. These pieces of equipment are permanently subjected to be inspected and maintained during total shutdown of plant facilities to execute Turnaround …

Carbon Capture Efficiency in Natural Gas Combined Cycle Power Plants: Analyzing the Effects of Variable Load Operations
Natural gas power generation retrofitted with carbon capture technology is poised to play a crucial role in ensuring energy reliability amidst the transition to variable renewable energy resources. While natural gas generation is used primarily for baseload power, it is expected to transition …

Rethinking CCS - strategies for technology development in times of uncertainty
… emission standard that would require new coal plants to install CCS. Using a stochastic generation expansion model, this thesis concludes that low natural gas prices make fuel switching rather than CCS investment the most likely compliance method. Moreover, should these standards be gradually …

Vulnerability of Coal- and Natural Gas-Fired Power Plants to Climate Change
… will reduce the efficiency (η) of thermoelectric plants by 0.12-0.45% for each 1°C of warming. In Chapter 2, we evaluate these predictions using historical performance data for 39 open- and closed-loop, coal and natural gas plants from across the U.S., which operated under daily and seasonal …

New York City local law 97 : an analysis of institutional response & decision making towards groundbreaking carbon emissions legislation
… code to achieve certain reductions in greenhouse gas emissions by 2050. The Act comprises a series of ten bills passed by the New York City Council including a tax on paper bags, a green roof mandate, and a process to close oil and gas plants around the city, amongst others. One major portion of …

Essays on Efficient Policy Interventions in Electricity, Natural Resource, and New Technology Markets
… second chapter studies the Regional Greenhouse Gas Initiative, a cap and trade program for CO2 emissions from electricity generators in the northeastern United States. I show that while RGGI CO2 allowance prices reduced emissions from coal plants within the RGGI area, allowance prices also …

Remediation and reuse of a former manufactured gas plant site in Champaign, IL
… contamination associated with manufactured gas plant sites by using in situ remediation. Another aim was to speculate an adaptive reuse of the site through revelatory design such that it unfolds the history of manufactured gas plants as they existed in 1800s to mid 1900s and also to educate …

Modeling methane emissions in oil and gas industry: pathway for measurement-informed inventories
Methane emissions from oil & gas (O&G) operations are under increasing scrutiny due to their climate impact and the growing demand for transparent emissions reporting. This work presents the results from two studies that are under the same scope. 1) The development of a mechanistic emissions model …

Energy and environmental contexts of cities, transportation systems, and emerging vehicle technologies : how plug-in electric vehicles and urban design influence energy consumption and emissions
… include operational energy use (e.g., gasoline for vehicles, electricity and natural gas for buildings) and embodied energy used to produce materials and construct buildings and infrastructure. Case study neighborhoods in Austin, Texas, and larger-scale regional models suggest that …

An analysis of the potential economic impact of natural gas production in Tanzania
Following substantial discoveries of natural gas in recent years, Tanzania has new options for economic development. The country's policy makers are faced with having to make decisions about how best to utilize the gas in order to drive economic development The options before the government are …

Leveraging System-Level Analyses and Techno-Economic Modeling to Inform the Viability of Electrochemically-Mediated CO₂ Separation
… it is also predicted that coal and natural gas plants will remain operational in the near term to meet growing energy demands. This, coupled with the persistence of hard-to-decarbonize processes, requires point-source capture technologies to mitigate remaining CO₂ emissions. State-of-the-art …

Assessing the impacts of increasing transmission capacity on the electric power sector in New England
… Through all policy scenarios, combined-cycle gas plants (GasCC) with carbon capture and storage (CCS) technology dominate the capacity expansions. Increases in transmission capacity lead to higher shares of wind in generation, especially when both transmission and interconnection are expanded. …
