In this work we make a first, partial, assessment of the lowto medium-temperature geothermal reserves of Mexico. The assessment covers about 30% of the identified geothermal surface manifestations. For reserve assessment we use the volume method, supplemented with Montecarlo simulations and statistics, in order to quantify the inherent uncertainties. We estimate these reserves as lying between ...
The modelling and simulation of fracture networks is a critical component of the assessment of hot dry rock (HDR) geothermal resources and of the design and creation of enhanced geothermal systems (EGS). The production of geothermal energy from an EGS depends on fluid pathways through the HDR and thus connectivity of fractures is essential. One way of assessing and modelling fracture connectivi...
In order to face the growing energy demands, renewable energy sources can provide an alternative to fossil fuels. Thus, low-enthalpy geothermal plants may play a fundamental role in those areas— such as the Province of Viterbo—where shallow groundwater basins occur and conventional geothermal plants cannot be developed. Thismay lead to being fuelled by locally available sources. The aim of the ...
Low temperature geothermal systems are an abundant energy resource in New Zealand with over 260 sites with a resource temperature of 150°C and lower. The Organic Rankine Cycle (ORC) is the standard process for low temperature energy conversion with commercial ORCs utilizing temperatures as low as 90°C, with one site at Chena, Alaska (discussed below) utilizing temperatures as low as 74°C. The a...
Efforts to characterize geothermal supply have long been focused on the aspect of power generation [Petty, et al., 1992], [Petty, et al., 2007], and [Augustine, et al., 2010]. This paper focuses on an approach to characterize the supply curve of hydrogeothermal energy that can be used for direct use in the United States. It aims to compensate for the absence of research on thermal uses and prov...
