    |
|
There are three parts to using solar energy efficiently;
efficient collection or generation of energy
efficient storage and
efficient use to offset demand loads.
Of these three the missing link is typically the storage efficiency of the collected electrical or thermal energy from the sun. I am looking for input regarding projects using efficient long term storage that would empower collection of energy during the hot summer months and use during the winter months. A seasonal cycle rather than a daily cycle.
Specifically requesting any information on long term electrical starage and long term thermal storage of energy.
Can it be done?

I was reading a magazine article on the bus this morning about Ground Source Heat Systems, incredibly popular in Scandinavia. It described how they sometimes used solar panels to replace some of the warmth extracted from the ground during the winter (I think). Even the ambient temperature of the ground can be a limited resource if all your neighbours are also using it!
GSHP's are probably the closest thing to what you describe, a heat source in Winter and a heat sink in Summer. |

I saw a news segment not long ago where someone was converting solar energy into hydrogen and storing it in tanks on site. It also powered their car.
