Water and Energy for Climate Change

Water and indoor air, waste heat and solar heat, distillation and absorption

We use membrane distillation and desiccant recovery systems to turn low-grade waste heat or renewable solar PVT heat into high-quality and indoor air. 

Waste heat is produced by a lot of industrial, domestic and energy production processes, and plays a significant part in rising global temperatures. With the WE4CC-II project, we saw a way to harness this waste heat to produce high-quality water and indoor air (humidity) control, which can substantially reduce energy consumption and CO2 emissions. 

WE4CC-II uses membrane distillation technology to produce the water, which is a thermally-driven separating process where water vapour passes through a hydrophobic membrane and high-quality liquid is retained. For air de-humidification, we use desiccant recovery systems.
