Exploitation And Utilization

With the popularization and application of Ground Source Heat Pump (GSHP) technology and the expanding scale of shallow geothermal exploitation, the environmental impact in the process of development and utilization is receiving more and more attention. According to the characteristics of ground source heat pump engineering, eBalance software is used to conduct research on life cycle environmental impact assessment. The result shows that more than 60% of resources consumption potential, acidification potential, and global warming potential derived from the process underground construction, and the eutrophication potential mainly derived from ground construction, underground construction, decommissioning with the contribution of 40.24%, 30.67% and 28.99%. According to the results, we put forward several reasonable control measures to ease the environmental impact in the process of geothermal exploitation and utilization for heat pump project.

Comparative Life Cycle Assessment

Ground source heat pump (GSHP) systems are an extremely efficient space heating and cooling technology. There is a large consensus throughout the literature that GSHP systems can reduce operational CO2 emissions by up to 80% in comparison to natural gas furnace (GF) and air conditioner (AC) systems. The literature is limited; however, in regards to the specific environmental impacts associated with the systems, as well as the impacts that occur throughout the systems’ entire life cycle. In this project, a comparative life cycle assessment was conducted to compare a GSHP system with a GF/AC system, examining 14 specific environmental impact categories. Results were consistent with the literature in regards to the operational stage; however the GSHP system displayed a significantly greater overall environmental impact. While these results are specific to the region of Ontario, Canada, they call into question the prevailing opinion that GSHPs are the more environmentally sustainable option.
