2What is a solar pond?A pool of saltwater which acts as a large-scale solar thermal energy collectorIt includes an integral heat storage for supplying thermal energy
3How do solar ponds produce electricity The water in the lowest layer heats up to ≈90°CThe fluid inside the pipes turns into steamThe steam moves the turbineThe turbine produces electricity
4Essential requirements for a solar pond SpaceWaterSaltSun
5Energy Comparison Energy Source Generating Cost (Euro per kWh) Range of PowerOil0.251kW-10MWCoal0.031MW-1GWGasSolar PV0.8010W-10MWWind0.07100W-100MWBiomass0.041kW-150MWSolar Pond0.1331kW-5MW (unlimited)
6Advantages Environment friendly energy – no pollution! Reliable energy sourceStores heat, so it can be used 24/7/365Can be constructed according to requirementsLow maintenance costs
7Disadvantages Localized Low efficiency Space availability Salt and water supply
8MAIN PROBLEM! Efficiency Low efficiency due to: Heat losses Bottom lossesTop lossesRadiation lossesMAIN PROBLEM!
13The Zebra Layer® All In One solution Insulation + heat exchanging pipesPeople can easily and fast build new Solar pondsJust lay down the foilCreate the salinity gradientYour Solar pond is ready to use!Really cheap
15Conclusions Reasons of solar ponds failure Our “zebra layer” solar pondComplicated installationEasy to buildNot efficient enough (only 17%)MORE EFFICIENT!!!We hope and believe that solar ponds have the potential to become an important source of energy in certain areas, and that the zebra layer will improve their functioning.
