Water and Energy for Climate Change

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.
