Google AI: The Three Operational Phases
• Charging (Energy Input): Heat from a source—like a solar thermal array or industrial waste heat—is applied to a wet desiccant. This drives off the moisture, leaving behind a dry, high-concentration desiccant material. [1, 2, 3, 4, 5]
• Storage (Energy Retention): The dried desiccant and the separated water are stored in separate tanks. Because the energy is stored in a chemical potential state rather than as sensible heat, it does not dissipate over time and requires no thermal insulation. [1, 2, 3, 4, 5]
• Discharging (Energy Output): When heat is required, liquid water or water vapor from humid air is reintroduced to the dry desiccant. This "watering" process creates an exothermic reaction (heat of sorption), generating heat that can be used for space heating or domestic hot water. [1, 2, 3, 4, 5]
Common Desiccant Materials
Systems utilize either liquid or solid desiccant materials depending on the application design: [1, 2, 3, 4, 5]
Desiccant Type: Common Materials Key Advantages.
Liquid Solutions Calcium Chloride (CaCl₂), Lithium Chloride (LiCl) Easy to pump, scaled its able with single or stratified tanks, can double as a liquid dehumidifier.
Solid Matrices Silica gel, Zeolites, Composite salt-matrices High structural stability, zero risk of corrosion, simple gravity-fed or fixed-bed as high eficiency heat in electricity.
Dlsclosure.
In our turn, we use a separate close tank equipped by input for humid natural air, and by its slightly turbulizers, and by a pair of small quantity of desiccants alternately operated one inside the said tank for energy production and humid extraction, while the second is dewatered as a by-product.
Natural air intakes with a big velocity (about 25 m/s) and turbulizers are needed to accelerate productivity, a small quantity of desiccant allows lower energy loses, deeper thermochemistry, higher temperature, and bigger effectiency heat in electricity.
How it can work.
E (kWh) is electricity annual production, so (E * 3600 sec. /0.3 efficiency) / (40.66 kJ /18 g.) gram H2O /10^6 = (E * 5.3/ 10^3) m3 of the H2O annually, can be separated and simultaniously condenced air humidity, producing a hight temperature clean water vapor and energy. Water and electricity in hotest deserts can be not a dream, but reality.
CaCl2 + 4H2O = CaCl2 * 4H2O exothermic process of 320 C temperature.
The Germany as example. E = 500 * 10^9 kWh electricity, annually + the water of ( 5.3 / 10^3) * 500 * 10^9 /10^6 = 2.7 * 10^9 m3, so 2.7 * 10^9 * 10^6 /7.5 g/m3 of the air = 360 * 10^12 m3 of the air treated annually, or 24 * 10^6 m3 air /sec., and if 10^6 air separators, it is 24 m3/sec. each.
