Abstract

In this paper, fluids that undergo endothermic reactions were evaluated as potential chemical energy carriers of heat from geothermal reservoirs for power generation. Their performance was compared with that of H₂O and CO₂. The results show that (a) chemical energy carriers can produce more power from geothermal reservoirs than water and CO₂ and (b) working fluids should not be selected solely on the basis of their specific thermo-physical properties but rather on the basis of the rate of exergy (ideal power) they can deliver. Finally, this article discusses the results of the evaluation of two chemical energy carrier systems: ammonia and methanol/water mixtures.

Thermocatalytic Heat Pipes for Geothermal Resource Recovery

Technical Report McGrail, Bernard P. ; White, Mark D. ; White, Signe K. ; ...

Heat pipes are an important technology that allow orders of magnitude faster heat transfer than simple conduction. However, operating principles in heat pipes place fundamental bounds on their performance (critical heat flux and efficiency). Conventional heat pipe functionality is inherently tied to vaporization and condensation of the working fluid charged in the heat pipe. These fluids each have different operating temperature ranges based on the capillary, entrainment, sonic, and boiling limits of the heat pipe design. These limits, typically the capillary limit, dictate the maximum heat flux a heat pipe can carry, and most importantly for geothermal systems, the distancemore »« less

Thermal effects on geologic carbon storage

Journal Article Vilarrasa, Victor ; Rutqvist, Jonny - Earth-Science Reviews

One of the most promising ways to significantly reduce greenhouse gases emissions, while carbon-free energy sources are developed, is Carbon Capture and Storage (CCS). Non-isothermal effects play a major role in all stages of CCS. In this paper, we review the literature on thermal effects related to CCS, which is receiving an increasing interest as a result of the awareness that the comprehension of non-isothermal processes is crucial for a successful deployment of CCS projects. We start by reviewing CO₂ transport, which connects the regions where CO₂ is captured with suitable geostorage sites. The optimal conditions for CO₂ transport, bothmore »« less

Two-step fuel oxidation to improve efficiency in the conversion of chemical energy into work

Conference Bisio, G ; Rubatto, R ; Marletta, L

It is well known that in the conversion of chemical exergy into work a remarkable percentage of exergy is destroyed during the combustion process. Obviously, hypothetical reversible combustions, as proposed in some papers, are not to be taken into account. On the contrary, recent studies of a new system to increase the efficiency of the conversion of chemical exergy into work appear interesting. The proposed system includes a gas turbine system with chemical-looping combustion where a metal oxide is used as an oxygen carrier. Instead of conventional combustion, the oxidation of fuel is carried out in a two-step reaction. Themore »« less
Exergy of air, CO₂, and H₂O for use as geothermal fluids

Journal Article Phuoc, Tran X. ; Massoudi, Mehrdad ; Wang, Ping ; ... - International Journal of Heat and Mass Transfer

Geothermal energy refers to the thermal energy naturally stored in the hot rock formation buried deep beneath the Earth’s surface. To harvest this source of energy, a fluid is pumped down in a set of injection wells, circulates through the hot rock and then is collected via a set of production wells for heating or other purposes. Furthermore, the selection of this fluid is an important component of a geothermal system. In this work, we review, evaluate, and develop the fundamental equations that can reliably predict the thermodynamic and the transport properties of air, CO₂, and H₂O. Using these equations,more »« less

CO2 Plume Geothermal (CPG™) – Innovative, Dispatchable Geothermal Power Production Using Non-Water Working Fluids

Technical Report Randolph, Jimmy

Purpose of the research. In DOE SBIR Phase I topic 11.b, Dispatchable Geothermal Operations, DOE seeks technologies and approaches that will enable geothermal to be deployed as a dispatchable, on-demand power source. TerraCOH’s CO₂ Plume Geothermal (CPG) and Earth Battery technologies are ideally suited to meet this objective. These technologies constitute a continuum of renewable power and geologic energy storage systems that are innovative in their use of non-water, and combinations of water and non-water, fluids as the working media to harness geothermal heat and store energy in subsurface formations. The non-water fluids – primarily CO₂ – will allow usmore »« less
