The future of

thermal energy storage

Carbon neutral heating and cooling

Cheap, green, and constant.
The solution to storing your solar energy to deliver carbon neutral heating and cooling 24/7 365 days of the year.

The Problem

The use of solar power to provide constant heating and cooling is limited by a lack of cost effective storage requiring solar power users to supplement their energy supply when the sun isn’t shining.

This is generally achieved with back up from mains gas or electricity.


HVAC TES, our solution, is a thermal energy storage system that can fully replace fossil fuels to provide heating and cooling in industrial and commercial settings.

The system is cheap, easily made and quickly deployed. Excess power from solar panels is stored as thermal energy for up to two months and delivered when required as either heating or cooling – enabling full utilization of solar panels throughout the year.

A number of corporations have pledged to achieve net zero emissions by 2025. Our system can fully remove emissions associated with heating and cooling, saving an estimated 40 percent of energy consumption.

The thermal energy storage system uses a flexible rubber coated fabric tank to store hot and chilled water. The quantity of each is regulated by a controller that responds to temperature changes and weather forecasts, delivering heating or cooling as required.
