BILLINGNatural Resources Coard. Solar Budget
BUDGET
(1980) 200 k$

Annual he~t sto~age could be the key to effective application of solar energy in
the Canadian climate . Sensible heat storage in rocks or water is too bulky
a~d costly to meet this need. Chemical heat storage can substantially reduce
size and cost, and hence make annual heat storage possible.

•

LONGRANGE
OBJECTIVES/DEFINITION
OF NEED
Develop an annual heat storage system to transfer excess summerheat to winter
use.

•

1980 KEYRESEAKCH
OBJECTIVES
l.
2.
3.
4.

•

Select salt mixes and eutectics for high transition heats at suitable
temperatures for solar applications.
Multi-cycle test prime candidates.
Encapsulate prime candidates for testing in fixed-bed heat exchange to
develop a scale-up model.
Explore other attractive heat storage techniques.

CURRENT
STATUS/RECENT
ACCOMPLISHMENTS
l.
2.
3.
4.

Found salt mixes can be used to tailor temperature of phase transitions.
Demonstrated polyethylene oxide prevented separation of glauber salts in
a 50 cycle test.
Showed plastic encapsulated spheres of water (base case) gave excellent
temperature stratification
in storage.
Selected and tested a eutectic
for comparison of phase change behaviour
with the base case.

INCENTIVES/JUSTIFICATION
• Annual
storage could eliminate
the number of collectors

(or reduce) the back-up system, as well as reduce
needed and hence offset costs as well.
