Competitive electricity generation
Using artificial solutions provides the flexibility to choose the salts and the conditions that maximise the productivity of the Reverse ElectroDialysis process, generating up to 10 times more electricity than when using natural water streams. RED Heat-to-Power is on track to achieve the highest efficiencies and lowest costs for converting low grade heat to electricity.
Exploiting widely available low-grade heat
The system can be installed practically anywhere in the world as low grade heat can come from renewable sources like solar or geothermal at very low cost. A very attractive application is to install the system at industrial sites where there is need for electricity, while waste heat is and its disposal is an issue that the industry has to deal with.
Offering flexibility to the power system
The technology is a fully controllable source of electricity: the regeneration step can be operated to match the heat availability profile and the saline solutions can then be stored at no cost in simple tanks for as long as required. This flexibility is a distinctive advantage over variable renewable energy, but also against conventional thermal technologies, which are not very flexible.
A safe and clean source of energy
The technology involves only simple circulation pumps and any noise will be minimal, while it is modular and can be housed in any kind of building raising no visual or aesthetic issues. There are very low requirements for operation and maintenance, making it suitable for any kind of application. It is operated at atmospheric pressure reducing the risks for accidents.
