157. Environmental aspects of geothermal technologies: the contribution of GEOENVI to the description of risks and impacts and related mitigation measures

Adele Manzella (CNR)

10/10/19, 2:30 PM

Topic 7: Sustainability, Environment and Regulatory Framework

Oral

Despite the main contribution that deep geothermal technologies bring to the energy transition from fossil to renewable resources in many European countries, in some regions these technologies are confronted with a negative perception, particularly in terms of environmental performance, which could seriously hamper their market uptake.
The evaluation and effective communication of...

144. Life-Cycle Environmental Impacts of Individual and District Geothermal Heating and Cooling in Geneva

Mrs Astu Sam Pratiwi (Renewable Energy Systems, University of Geneva)

Topic 7: Sustainability, Environment and Regulatory Framework

Oral

In 2017, the energy delivered for heating purposes of buildings in the State of Geneva in Switzerland came from oil- and gas-fired boilers, which led to negative impacts on air pollution and global warming. The 2035 target of the State of Geneva is therefore to reduce the annual heat consumption to 29 GJ/capita, from which 34% should come from renewable energy or waste heat recovery. The State...

148. A case study on the intensive shallow geothermal usage in a German neighborhood

Mr Boyan Meng (Helmholtz Centre for Environmental Research - UFZ)

10/10/19, 3:00 PM

Topic 7: Sustainability, Environment and Regulatory Framework

Oral

Ground source heat pump (GSHP) systems has become a renewable technology to provide space heating and cooling. An evident trend is the intensive exploration of shallow geothermal heat within a limited area, e.g. residential quarters. In such context, thermal interaction among nearby installations is often expected, which leads to concerns about the subsurface environment and the system...

152. Meeting Site-specific Energy Demand With a Fully Renewable Power System

Ms Anna van Brummen (ETH Zurich)

10/10/19, 3:15 PM

Topic 7: Sustainability, Environment and Regulatory Framework

Oral

In electricity grids, demand and generation must be balanced at all times. Modern electricity is primarily generated by constant power sources, such as nuclear and coal, and quickly dispatchable sources, such as gas fired power plants, which can be adjusted based on small demand variations. However, as anthropogenic total CO$_2$ emissions already make up almost 75% of the atmosphere's total...
