MemPower: Clear Water And Electricity from Ocean Water

MemPower, clean drinking water and electricity from ocean water

You can also use it for processes in industry such as the energy and chemical sector and the food and bio-based industry.

While there is plenty of water in the world, good-quality drinking water can be scarce. MemPower employs membrane distillation using solar or residual heat to produce very pure water.

This new technology does not need electricity but generates it instead, so clean drinking water and electricity are produced from saltwater at the same time.

Wageningen University & Research is looking for partners to further develop and market this promising innovation, which won the MBR Global Water Award in 2017.

Bacteria instead of Lithium?

Bacteria battery by Sam Molenaar

Sam Molenaar believes that, with further optimization, the bacteria-based battery could rival the performance of lithium-ion batteries at a lower cost and with greater safety.

A rechargeable battery driven by bacteria? Lithium-ion batteries are limited by safety issues, high costs and other factors. Sam Molenaar and his colleagues from Wageningen University wanted to come up with a less expensive, more sustainable solution. 

The research team combined two separate microbial energy systems. One system used bacteria to form acetate from electricity, while the other one converted the produced acetate back into electricity. Read More
