High <strong>Solar</strong> Fraction ⇒<strong>An</strong>nual Heat Storage<br />

Heat storage types:<br />

– Sensible: need ~5-30 kGal (w/ efficient house)<br />

– Costly, bulky, “formidable”<br />

– Thermochemical heat pump/liquid desiccants<br />

– High energy density possible (1/6 th that <strong>of</strong> sensible)<br />

– Can use flat-plates at ~160 o F<br />

– Integrates well with solar-driven cooling in summer<br />
