Two Technologies,
One Vision
Kaaj offers two proprietary technologies designed in various configurations to optimize energy efficiency, reduce greenhouse gas emissions, and store and reuse electricity. These innovations cater to a wide range of commercial and industrial applications, ensuring reliable and economically viable solutions that lower both capital and operating costs.
Kaaj’s solutions are offered as HaaS (Heat as a Service) solutions, which eliminates the upfront costs and financial risks for the customer.
At the core of Kaaj's technologies is the Thermal Energy Storage (TES) device. Utilizing abundant, low-cost, high-density granular natural material as a heat storage medium and transfer surface, our TES system eliminates the need for conventional heat exchangers. This approach significantly reduces both costs and the environmental footprint of our solutions.
To ensure reliability and mitigate hardware risk, Kaaj's main sub-systems are sourced from off-the-shelf equipment. These components are built with mature technology, guaranteeing a long lifespan of over 20 years for our solutions.
Waste Heat Recovery (WHR)
To re-purpose industrial waste heat to useful heat such as material pre-heating, process heating, space heating, hot water, or steam.
Since the source of the energy is wasted heat, these solutions generally have short payback.
The source of the heat could be the flue gas of cement and glass plants, the exhaust of boilers, and the exhaust of gas turbines/engines.
When the available heat has a temperature over 600°C, The solution could also include a power module to provide Electricity in addition to the heat.
ElectroHeat Storage (EHS)
To electrify the heating process, this solution comprises an electrical heater and a TES unit. The heat is generated during the excess power periods and overnight low-carbon periods, stored in the TES unit, and supplied on demand.
This solution is modular and scalable, which minimizes the cost as well as the design, assembly, and installation process time.
When coupled with a power module, this solution could also provide electrical power during the peak demand hours.
