ENVIRON 2014, Dublin - Tracey & John present latest Hydro-BPT work
Tracey Lydon & John Gallagher both attended the ENVIRON 2014 conference held in Trinity College Dublin at the end of February. They presented to an international audience of researchers and policy makers from various backgrounds in environmental science.

Tracey’s presentation was entitled ‘Energy Efficiency of Water: Analysis of Pumps-as-turbines replacing Pressure Reducing Valves in Distribution Networks’. The presentation focused on experimental analysis of pumps-as-turbines (PATs) in order to determine their viability of replacing pressure reducing valves in distribution networks (WDN). The analysis includes verifying PATs efficiency for typical diurnal flow patterns representative of the WDN and related optimal arrangements and adjustments of PAT arrangements, which are conducive to highest energy recovery, with the aim of resulting in more energy efficient water distribution.

John presented some of his work on Life Cycle Assessment (LCA) of Micro-hydropower (MHP) installations. His presentation was entitled ‘Assessing the Environmental Impacts of Micro-hydropower in the Water Industry’. The ongoing work presents the environmental impacts associated with MHP as the embodied carbon within the materials of a renewable energy project are generally not reported. The presentation discussed the procedure related to carrying out a LCA and showed the results from several case studies. The conclusions from the studies showed a low carbon payback for the case studies range from 0.1-0.7 years in comparison to an economic payback of 5-10 years.
