Problem
Residential and commercial buildings face increasing heating and cooling costs, coupled with a desire to reduce reliance on traditional energy grids and embrace sustainable solutions. Current heat pump technology may not be sufficient as electricity prices continue to rise. There is a need for affordable and efficient thermal energy storage solutions that can integrate with renewable energy sources.
Solution
Batsand provides a thermal energy storage (TES) system that utilizes a proprietary heating generator to store energy in a sand vessel. This "sand battery" can be charged during warmer months and then used to supply heating or cooling throughout the year. When coupled with solar panels, the system offers a fully off-grid solution, reducing reliance on the electricity grid and lowering heating and cooling costs. The system works by blowing heated or cooled air generated by Batsand's proprietary system into a sand container built according to their specifications. Air is then recirculated to warm up an air/water heat exchanger connected to the building's heating system.
Target Audience
The primary target audience includes homeowners and businesses seeking to reduce their heating and cooling costs, achieve energy independence, and adopt sustainable energy solutions.
