Environmental impacts of aquifer thermal energy storage investigated by field and laboratory experiments

Aquifer thermal energy storage (ATES) uses groundwater to store energy for heating or cooling purposes in the built environment. This paper presents field and laboratory results aiming to elucidate the effects that ATES operation may have on chemical groundwater quality. Field data from an ATES site in the south of the Netherlands show that ATES results in chemical quality perturbations due to ...

Numerical modeling of aquifer thermal energy efficiency under regional groundwater flow: a case study at Oslo Airport

The main purpose of this paper is to present a robust forward model for simulating extraction and storage of thermal energy in an aquifer. The model is a local three-dimensional finite element model with boundary conditions derived from an analytic large-scale model based on the regional water balance. Numerical investigations and thermo-hydraulic evaluation of a typical dipole ...

Effects of aquifer thermal energy storage on groundwater quality and the consequences for drinking water production: a case study from the Netherlands

We used data from an aquifer thermal energy storage (ATES) system located 570 m from a public water supply well field in the south of the Netherlands to investigate the relation between production of renewable energy with an ATES system and the production of drinking water. The data show that the groundwater circulation by the ATES system can impact chemical groundwater quality by introducing ...

Thermally Enhanced Soil Vapor Extraction

Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

In Situ Thermal Treatment for Soil, Sediment, and Sludge

The main advantage of in situ thermal treatment is that it allows soil to be treated without being excavated and transported, resulting in significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the process is ...

Case study - Using thermal storage systems to reduce carbon emissions

Aquifer Thermal Energy Storage (ATES) systems have the potential to provide a significant tool for climate change mitigation. Using aquifers as a source for thermal energy can provide heating and cooling for houses, offices and other buildings E-USE (aq). In comparison to the use of fossil fuels, as well as providing up to 60% CO2 reductions, these systems are also more cost effective. The ...

Impacts of Shallow Geothermal Energy on Groundwater Quality

The use of shallow geothermal energy (SGE) systems to acclimatize buildings has increased exponentially in the Netherlands and worldwide. In certain areas, SGE systems are constructed in aquifers also used for drinking water supply raising the question of potential groundwater quality impact. Impacts of Shallow Geothermal Energy on Groundwater Quality provides a hydrochemical and geomicrobial ...

Opportunities for public water utilities in the market of energy from water

An inventory is made of the possibilities to recover sustainable energy from the water cycle by identifying different water flows in a municipal environment as a sustainable energy source. It is discussed what role public water utilities should play in the market of energy from water. This is done for Waternet, the public water utility of Amsterdam, by describing experiences on two practical ...

Storing Heat Underground

Underground thermal energy storage (UTES) is a system that uses inter-seasonal heat storage, storing excess heat from the summer for use in winter heating, and the cooling potential from winter for cooling in summer. A cost-effective, low-energy and low-risk proven renewable technology, UTES reduces carbon emissions by up to 60% and is becoming an increasingly popular choice for residential, ...

Impact of dam operations on hyporheic exchange in the riparian zone of a regulated river

Abstract: Dam operations commonly cause large, frequent fluctuations in river stage, which persist for long distances downstream. The stage fluctuations force river water into and out of the hanks, defining lateral hyporheic exchange paths. To evaluate the penetration distance and rates ot dam-induced hyporheic exchange, we monitored water-table elevation, temperature. and specific ...

Case study - Pemaco superfund site remediation

OVERVIEW Pemaco was formerly a chemical facility located in a light industrial and residential area of Maywood, CA, adjacent to the Los Angeles River. No one knows how long hazardous substances had been leaking into the ground but the operations date back to the 1940's. Up until closure of the facility in 1991, chlorinated solvents, aromatic solvents, and flammable liquids had ...
