Hello.
I am at my university working on an idea if it would be possible to store heat energy in quicklime CaO.
We are to use a solar parabol to concentrate the sunlight and get a temperature in focus around 1000 C degres.
In that temperature it is possible to burn limestone to quicklime and then save it in a airtight storage.
1000 kg have about 320 kWh and can be bought in my country for around 45 $/1000 kg.
Does anyone know if we are wrong about this becouse it seems to easy to save energy this way.
To save energy to heat a house I need to burn around 15000 kg to be able to heat a house over the winter and I try to calculate how big solarparabol we need to build to be able to burn 15000 kg limestone to quicklime in a summer.
After the winter the reaction with water have turned CaO to Ca(OH)2 and it can be burned again to store energy for the next winter.
Do you think it is possible?
Have anyone heard if someone does something like this?
Nobody have tried it in my country so I hope someone out there know something.
I found a PDF-document that NASA did about it, so it seem possible.
