Utilisation of deep geothermal energy for heating purposes
The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

Thermodynamic analysis of a geothermal district heating system
Thermoeconomic analysis is considered a useful tool for investigators in engineering and other disciplines due to its methodology based on the quantities exergy, cost, energy and mass. This study deals with an investigation of capital costs and thermodynamic losses for devices in the Balcova Geothermal District Heating Systems (BGDHS). Thermodynamic loss rate-to-capital cost ratios are used for ...

Exergetic and sustainability performance assessment of geothermal (ground source) ejector heat pumps
Although ejectors have been used in cooling/refrigeration and Heat Pumps (HP) applications for a long time, utilisation of Geothermal Ejector Heat Pump (GEHP) with Ground–Heat Exchanger (GHE) is a new idea, which has recently appeared in the literature. In this study, we model a GEHP system with a GHE in terms of exergetic aspects and apply our model to this system in the heating mode. The system ...

What’s geothermal again?
Some green energy sources seem to have charisma; others struggle for public attention with little success. Solar energy is an “it” technology, as evidenced once again by the tremendous participation in the annual Solar Power International conference in Anaheim, California this week (Oct. 27-29). Twice as many companies (945) are displaying their wares in the Expo Hall this year, despite the still ...

Rational use and management of geothermal energy resources
This article identifies and explains several attributes of geothermal energy. High exergetic efficiency due to a close temperature tie between geothermal energy and district heating and cooling was noted. Parameters governing the rational use and management of geothermal energy systems with special emphasis on integrated-cascaded district energy systems were formulated and explained with two case ...

Permeable (pervious) pavements and geothermal heat pumps: addressing sustainable urban stormwater management and renewable energy
Water and energy are the two most fundamental ingredients of modern civilisation and are also the most precious and essential resources around the globe. They are inseparably coupled and with increasing pressures on these resources as the world's populations grow, the concepts of a combined approach can be applied while addressing the economic, climate, water and energy crises. Sustainable ...

Investigation of a hybrid solar and geothermal driven absorption cooling system for district applications
In this paper, a new hybrid geothermal and solar driven absorption cooling system (ACS) is proposed for low–temperature district energy applications. Two approaches are proposed in this study, namely: a) a new model for determining the specific entropy values of LiBr–water solution and (b) two new energetic and exergetic parameters, namely geothermal contribution index and solar contribution ...

Top 5 Reasons Homeowners are Ditching Oil Furnaces and Switching to Geothermal Heating and Cooling
You’d be hard-pressed to find a home heating option that’s as expensive, dirty, and inefficient as fuel oil. It’s no wonder that homeowners are upgrading to clean, renewable, energy-efficient geothermal heating and cooling in record numbers. Here are the top five reasons why folks are making the switch: 1. Geothermal saves homeowners thousands of dollars Any homeowner who ...

Heat as a by–product or sub–product of CO2 storage in mafic and ultramafic rocks
Since carbonates are at a lower energy state than free CO2, storage through carbonation of silicate rocks is thermodynamically favoured and proceeds spontaneously by releasing heat. In an in–situ CO2 injection site, the heat released in these exothermic reactions can be exploited in a geothermal power–plant, effectively contributing toward the economic viability of the storage process. Our ...

Case Study - Evaluating Geothermal Potential - Ravenna, Italy
University of Bologna researchers carried out an investigation of the thermal properties of the coastal aquifer at Ravenna Italy in order to evaluate its geothermal potential for residential heating. As part of that investigation, they measured the water temperature versus depth at 56 piezometers. EnviroInsite was then utilized to establish the relationship of water temperature with land use, ...

What energy efficiency type are you?
By Elisa Wood July 29, 2010 Not so long ago, consumers seemed to like energy efficiency just a little bit more than going to the dentist. Clearly that has changed, as evidenced by the recent run on appliance and home retrofit subsidies in several states. Greens are no longer alone in swooning over front loader washing machines and geothermal heat pumps. But who exactly are these new energy ...

Fission, Fusion, What's the Confusion?
Clean, sustainable, and renewable energy is a hot topic. Our world runs on energy and our production and use of energy shouldn’t put us or future generations in harm’s way. Society has responded to increasing power demands with technology such as nuclear fission. Fission splits uranium into smaller elements and releases large amounts of energy used to heat water in nuclear reactors ...
