Applications & Installations

There are 3 critical factors that make a successful heat to power project:

Heat

The quantity of heat available will determine the amount of power that can be generated from the heat source. For information on assessing a heat source, visit the How a site comes together page

Up-time

The more hours the heat source operates per year, the better for heat to power projects. There are 8,760 hours in a year and ideally the heat source runs for greater than 7,000 of them

Value of electricity

The Clean Cycle can deliver value in a variety of ways including reduced electrical load, carbon offsets, and increased operational efficiency. Typically, the most prominent benefit that the Clean Cycle brings is in the value of each kilowatt of electricity it produces.

Common Applications

Example applications that have delivered numerous successful installations include the following:

Liquid fuel engines

Clean Cycle generators can pair with single or multiple engines to substantially increase the overall fuel efficiency of generator installation. On a typical high speed diesel Engine, one Clean Cycle generator will offset 150,000 liters of fuel per year. Regardless of the fuel type - including diesel, fuel oils, LNG, etc. - the engine produces heat that the Clean Cycle can convert into electricity.

Gas engines

The Clean Cycle can add valuable additional electrical output from the waste heat of biogas engines, which often qualify for lucrative feed-in-tariffs. The Clean Cycle has demonstrated success on landfill gas engines, biogas engines, waste water treatment plants.

Other process heat

Any industrial facility where biomass is involved, whether it's a cement manufacturing facility, flare, engine, flue, etc.

Compression stations

Compression stations used throughout the world transmit gas and oil from one destination to another and produce heat in the process. Both turbine compressors and engine compressors are suitable heat to power candidates and the electricity produced can be used directly on-site.

Turbines

Turbines that generate electricity or are used for compression create a substantial amount of heat in their exhaust. Small scale microturbines can also be utilized in series to extract enough heat for generating electricity.

Biomass boilers

Boilers and other combustion systems using forms of biomass have been used for many years to dispose of waste or industrial by-products, such as farm and sawmill clippings, refuse, and even forms of biogas. The combustion process can be used to heat water that can be delivered to the Clean Cycle unit to turn the waste into valuable electricity.

Example Installations

One unit on two landfill gas engines in the United Kingdom

In the United Kingdom, landfill gas engines supply heat to operate one Clean Cycle unit. One engine didn’t have sufficient heat, so the exhaust from 2 x 1MW engines was captured and delivered to the Clean Cycle containerized solution. This Clean Cycle has generated greater than 38,000 operating hours.

Four units running on the heat of a cement kiln in the United Kingdom

The four containerized Clean Cycle units operate on a single heat source at a biomass fired lime kiln in the United Kingdom. The Clean Cycle units generate enough electricity to decrease electrical demand on-site by approximately 25%.

One Clean Cycle unit operating on a landfill gas engine in France

In France, a single Clean Cycle unit is connected to the exhaust and jacket water heat of a gas engine that operates continuously on landfill gas. The engine, being located on the landfill, had no heat utilization options nearby, so the Clean Cycle solution was an excellent fit to generate additional electricity and increase the efficiency of the site.

Two Clean Cycle units operating on the heat from a biomass boiler

In Italy, two Clean Cycle units generate electricity at a door manufacturing facility from the heat of a biomass boiler. Excess wood and sawdust from the door manufacturing operations feed the biomass boiler that produces heat for the building as well as two Clean Cycle generators.

One unit on one diesel engine using exhaust and jacket water heat

A Clean Cycle solution generates power from the waste heat of a 1.4 MW containerized diesel engine, operating continuously. Exhaust heat and jacket water heat are delivered to the Clean Cycle unit in two separate hot water loops. The use of some of the jacket water heat by the Clean Cycle unit can also reduce electricity consumption by the engine’s radiator.

Two units on two diesel engines in the Pacific Islands

On a remote island in the Pacific, 2 Clean Cycle units are connected to two fuel-fired engines. Only one of the engines operate at a time, but has enough heat to support both Clean Cycle units, so a clever exhaust ducting system was installed to ensure both Clean Cycle units run continuously, regardless of which engine operates.

One Clean Cycle unit operating at an oil and gas facility in Romania

In Romania, right by the Black Sea, a single Clean Cycle unit operates at an oil and gas facility. Large boilers heat up a steam loop that is used for oil and gas processing. As part of the process, low temperature boiler exhaust was vented into the atmosphere until a Clean Cycle was installed to utilize the low temperature heat and convert it into electricity.
