Next Steps
How a Site Comes Together
The flexible and modular design of the Clean Cycle Generator has made tapping into waste heat and converting it into electricity more simple than ever. Follow this five step process to make a site come to fruition in a matter of months.
1. Assess the heat source
The first step in any heat to power application is to determine how much heat is available and at what temperature. All we need to quantify the heat available is the temperature and flow rate of the medium. The amount of heat can vary throughout the day or seasonally, so we will typically ask for historical data over the previous year to get a better idea of how much heat can be captured.
2. Estimate electrical output
With a detailed picture of the inputs, we can run our internal model to provide a clear picture of how much power the Clean Cycle can produce for the specific site. We specialized in accurately quantifying the power we can produce for a particular site. We have looked at everything from single base-load engines to multiple engines run in cycles.
3. Understand site economics
Now that the heat available and power output are well understood, the next step is to determine how much the recovered heat is worth. To do this, we need to know the local cost of electricity. This can be the cost of generation or simply the typical price paid to the utility for each kWh of energy. With this information, we can calculate the annual revenue or savings generated by the Clean Cycle to calculate a return on investment for the project.
4. Create a site integration plan
Once the financials of the project make sense, HRS will work with the customer to develop a site integration plan. This covers all the details of the project from equipment placement to installation and commissioning. At this stage, HRS engineers will work with the customer site personnel to ensure a timely and reliable installation.
5. Execute and install
With a robust integration plan in hand, HRS will see the project execution through to commissioning and beyond. Whether installing through one of our partners or using local resources, HRS is committed to ensuring a quality installation that meets all customer requirements. After the site is commissioned, HRS will monitor the performance of the Clean Cycle, looking for any signs of wear or loss in power. If any problems arise, HRS personnel are just a phone call away.
FAQ

Q: How much does the Clean Cycle generator cost?
A: Depending on our scope of supply (heat delivery, condensing system, etc), the price of a Clean Cycle solution will vary. Please contact us to get a specific cost estimate.
Q: What heat sources can the Clean Cycle run on?
A: The Clean Cycle is heat source agnostic. Engines are our most common heat source. We are able to take heat from engines running natural gas, biogas, syngas, propane, diesel, HFO, or just about any other fuel. With dirtier fuels, like HFO and diesel, additional equipment and maintenance are required to clean the heat transfer surfaces. Outside of engines, we can use low pressure steam (4.5 bar or greater), pressurized hot water, flue gas from ovens, or any other hot stream. Check out our Applications page for more information.
Q: Is my site a good application for the Clean Cycle?
A: To run at full power, the Clean Cycle needs a stream with approximately 1,000 kWth of heat at a temperature of 155C for liquids or 200C for gases. This can often be found in reciprocating engines >1.4MW, turbines >1.2MW, and boilers >1MW of capacity.

Q: What is the pressure of the Clean Cycle unit?
A: The Clean Cycle operates at a max pressure of 24.5 bar.
Q: What is the lead time to ship a Clean Cycle unit?
A: This will depend on the scope of supply, but a standard unit can be ready to ship in as little as 16 weeks after receipt of PO.
Q: How many Clean Cycle units are in the field?
A: We have shipped more than 100 units and the fleet continues to grow.
Q: How many operating hours do Clean Cycle units have?
A: The installed base of Clean Cycle generators has accumulated greater than 1 million operating hours. It’s worth noting that the same core components used in the Clean Cycle have also been used in other technologies as well with over ten years of successful performance.
Q: Can the Clean Cycle withstand harsh environments?
A: We have designed the Clean Cycle to operate in a wide range of environments from freezing conditions to remote islands. For salt air conditions, we apply a protective coating and install a salt filter. Additionally, our condenser fins are coated with an anti-corrosion epoxy and most of the nuts and bolts are switched to galvanized or stainless. For cold environments, we have a container heater option and add additives to the water loops to prevent freezing.
Q: Can the Clean Cycle operate on “island mode” or as a prime mover for a grid?
A: The Clean Cycle is designed to follow a heat source, not be a prime mover for a grid. The power electronics also require a strong signal from the grid to create the appropriate frequency.
Q: What personnel are needed to run the Clean Cycle?
A: None during normal operation. If something goes wrong, the Clean Cycle will shut down and revert to a fail-safe configuration. Often we can remotely diagnose issues and get the system back up and running.
Q: How much maintenance is required?
A: Regular maintenance will enhance the life of any machine and the Clean Cycle is no different. Unlike most generators, the Clean Cycle does not have any oil or lubricants to replace. The primary regular maintenance is replacing filters. Less frequently, pump seals will be replaced and heat exchangers may need to be cleaned.
