Clean Energy Technologies (CETY) has successfully commissioned three of its Clean Cycle heat recovery solution (HRS) systems in Lebanon, Tennessee.

Clean Energy Technologies (CETY) has successfully commissioned three of its Clean Cycle heat recovery solution (HRS) systems in Lebanon, Tennessee.

The systems have been commissioned as part of a waste-to-energy downdraft gasification plant developed by US-based company Aries Clean Energy. The HRS converts waste heat into reliable electricity without additional fuel or emissions. 

Based upon an efficient, patented, high-speed turbine, the CETY Clean Cycle system is capable of generating electricity in a closed-loop organic rankine cycle by using relatively low temperatures. This type of system helps capture waste heat from a wide range of sources, such as water, exhaust streams, or steam processes.

Additional energy generated by the Clean Cycle system can be used on site or divested back to the power grid.

"CETY's Clean Cycle technology can increase efficiency, reduce costs, and increase revenue."

Aries Clean Energy's gasifier enables conversion of waste into a combustible synthetic fuel gas without any burning or incineration steps. Being thermo-chemical in nature, the high-temperature process uses very low levels of oxygen in a sealed, computer-controlled environment.

The new plant uses scrap tires, commercial wood waste, and biosolids from the adjacent wastewater treatment plant for feedstock. With 64t per day capacity, the plant can generate energy equivalent to supplying approximately 350 households and enables offset of nearly half of the total load at the waste treatment facility.

The plant is capable of reducing 2,500t of carbon emissions annually and will produce high-carbon content biochar, which can be sold both for agricultural and industrial uses.

CETY's chief executive officer (CEO) Kam Mahdi said: “Using the Clean Cycle, municipalities, industries, and businesses are able to recover a significant portion of this previously unutilised energy in the form of electricity.

“CETY's Clean Cycle technology can increase efficiency, reduce costs, and increase revenue, while lowering the carbon footprint, of existing production facilities and processes.”
