We've always being doing like that...
...nothing new so far!
Lab tests at Trinity College Dublin
Tests on PATs on a small and large scale
Why such technology isn't implemented everywhere?
Power output: 30 W 4 kW
Why should we care?
The technology: Pumps as Turbines (PAT)
- Low purchase price
- Compact dimensions
- Mass manufactured
- Short delivery time
- Easy maintenance
- Proven results
Hydropower energy recovery
Many opportunities in the water sector, significant potential

Bottlenecks to energy recovery and PAT implementation?
1) lack of knowledge/awareness about PATs and energy recovery potential
Tŷ Mawr Wybrnant, National Trust, Wales
Blackstairs Group Water Scheme, Ireland
2) lack of comprehensive PAT design guidelines
