“…Through the two-step process of favourability mapping and quantitative resource assessment, this study is the first to provide a focused examination of the geothermal resource potential of the entire British Columbian portion of the WCSB. Similar two-step analyses of the more densely populated island of Sicily, Italy, are not applicable in the WCSB, because they do not consider proximity to energy consumers or transmission infrastructure (Trumpy et al 2015;Trumpy et al 2016).…”

Mitigating climate change requires elimination of fossil fuel related greenhouse gas emissions. Transitioning electricity generation to low-carbon sources and substituting fossil fuels with electricity in non-electric sectors is considered to be a key strategy. This dissertation investigates resource options to and land area impacts of decarbonizing electricity generation and electrifying adjacent sectors. Three studies analyze transition options in the western Canadian provinces of Alberta and British Columbia. The first study investigates technology transition pathways and land area impacts of reducing electricity generation related carbon emissions in fossil fuel-dominated Alberta. A final 70% share of wind, solar, and hydro power reduces emissions by 90% between 2015 and 2060. This scenario requires designating 5% additional land area to electricity generation annually. Land is largely designated to the required space between wind turbines, with smaller areas attributed to ground-mounted solar and hydro power. System planners can reduce the land area impacts by deploying more compact geothermal, rooftop solar and natural gas with carbon capture and sequestration (CCS) technologies. These technology compositions can hold land area impacts constant in time if depleted natural gas and CCS infrastructure is expediently reclaimed, but total net present system costs increase by 11% over the 45-year period. Without reclamation, fuel extraction and carbon sequestration increase land area impacts at least fourfold within this time period. The second study investigates sedimentary basin geothermal resources in northeastern British Columbia. Geothermal energy is a potentially low-cost, low-carbon, dispatchable resource for electricity generation with a relatively small land area impact. A two-step method first geospatially overlays economic and geological criteria to highlight areas favourable to geothermal development. Next, the Volume Method applies petroleum exploration and production data in Monte Carlo probability simulations to estimate electricity generation potential at the four areas with highest favourability (Clarke Lake, Jedney, Horn River, and Prophet River). The total power generation potential of all four areas is determined to be 107 MW. Volume normalized reservoir potentials range from 1.8 xvi Dedication I dedicate this dissertation to my parents, Richard and Dagmar Palmer-Wilson, and to my grandparents, Gerhard and Ilka Radke. The weight of this work calmly rests on their unending love, support, patience and wisdom. "Wenn die Kinder jung sind, gib ihnen tiefe Wurzeln. Danach gib ihnen Flügel."

“…Geophysical methods were among the three main disciplines applied to explore geothermal resources, including geology and the chemistry of thermal fluids [1,7]. Eugenio et al [8] described a data integration tool used to identify potentially undiscovered geothermal resources in the island of Sicily. Freek et al [9] reviewed the potential of remote sensing for exploring geothermal resources.…”

Abstract:Geothermal energy is one of the cleanest sources of energy which is gaining importance as an alternative to hydrocarbons. Geothermal energy reserves in China are enormous and it has a huge potential for exploitation and utilization. However, the development of the geothermal industry in China lags far behind other renewable energy sources because of the lack of fiscal and taxation policy support. In this paper, we adopt the system dynamics method and use the causal loop diagram to explore the development mechanism of fiscal and taxation policies in the geothermal industry. The effect of the fiscal and taxation policy on the development of the geothermal industry is analyzed. In order to promote sustainable development of the geothermal industry in China, the government should pay more attention to subsidies for the geothermal industry in the life-cycle stage of the geothermal industry. Furthermore, a plan is necessary to provide a reasonable system of fiscal and taxation policies.

The overlying structural levels consist of basinal carbonates (Imerese and Sicanian), siliciclastic deposits (Numidian Basin) and the Sicilide Nappe.…”

a b s t r a c tThis paper presents a multidisciplinary methodology to estimate the underground heat-exchange potential for Borehole Heat Exchangers (BHEs) coupled with Ground Source Heat Pumps (GSHPs) over wide areas. The proposed methodology was tested in four sites in western Sicily (southern Italy) where the shortage of subsurface geological data, in addition to the undefined authorization processes for this kind of system, is probably the main barrier to planning and exploiting geothermal heat for heating and cooling purposes. Reliable high-resolution 3D geological and petrophysical models were built based on the integration of airborne electromagnetic data and laboratory measurements of the thermal properties of rock samples. A GIS-based procedure was applied to assess the geothermal heat-exchange potential using 3D models of thermal conductivity as the main input. The results of the analyses are represented by thematic maps of the underground heat exchange potential for BHEs coupled with GSHPs. The study areas show a generally high suitability for the use of this technology and several municipalities in the area could take advantage of the resulting maps for energy planning.
