Frequently Asked Questions

What is the CE5?

Simply stated, ClearEdge Power introduces a new application for proven technology.  Combined heat and power (CHP) fuel cells have demonstrated superior efficiency for years in industrial plants, universities, hotels and hospitals.  ClearEdge Power is now making it available on a residential and small commercial scale. Patented fuel cell technology in a compact system converts natural gas, propane, and eventually biofuels – into both electricity and heat.

How does it work?

The CE5 consists of three core components, modularly designed to slide in for ease of installation and maintenance. The Fuel Processor converts natural gas into ultra-clean hydrogen through a catalytic process, as opposed to burning the natural gas, reducing CO2 emissions. The hydrogen is processed through a Fuel Cell Stack, creating direct current (DC) power. The Power Conditioning Unit then converts the DC electricity into alternating current (AC), which then ties directly to the main electrical panel, providing steady continuous power for your electricity needs.

What are the best uses for the CE5?

The CE5 is scaled for large homes and small commercial operations where the energy load significantly exceeds the baseline utility allowance.  The CE5 generates around 5kW annually – optimal for larger homes (4,000 sq. ft. or more), especially if pools, spas and radiant floor heating are in plans.  It’s also a convenient source of back-up power for critical secondary energy users like refrigerator/freezers, electronics/computers and wine cellars.  Deploying the system’s heat energy efficiently to a home or business' hot water application displaces the electricity or gas otherwise used to create that heat, further reducing your energy bill. Retail outlets like fast food chains, coffee bars and health clubs will appreciate the operational savings achieved for hot water heating.

How do you install the CE5?

The CE5 is designed and built to fit in either an interior mechanical room or outside – running quietly in the background 24/7. Connected to the utility grid using standard fittings and tools, the CE5 easily integrates with existing electrical and hydronic systems and is compliant with utility interconnection requirements. In the event of grid interruption the system automatically switches to operate in a grid-independent mode to provide continuous backup power while the grid is down. It can also be modified to run off-grid if desired. The CE5 also uses a “smart” web-connected device with centralized command and control capabilities, enabling the operation of multiple units at site or working in parallel.

How much does the CE5 cost?

The list price for the CE5 is comparable to residential solar PV systems on a dollar per watt-installed basis. One advantage over solar, the CE5 generates eight times more energy than the same size solar installation. So, for the same capital investment, the CE5 gives you 80 MWh of annual combined electricity and heat, compared to approximately 10MWh generated by a 5kW solar system.

Operating costs for the CE5 are as low as 6.0¢ per kWh based on $1.20 per therm for natural gas, assuming full electrical and heat load utilization. The purchase price of the CE5 also includes a five-year EnergyPlus™ Service Agreement for all installation, parts and maintenance.

What incentives are available for the CE5?

The CE5 is eligible for substantial incentives and rebates: both California SGIP reimbursement and Federal Tax Credits will significantly reduce the net capital cost to the customer. And, unlike the intermittent nature of solar PV the CE5 provides a reliable, continuous energy resource at the point of load, operating 24/7. In addition, the CE5 receives 'net-metering' credit for any excess electricity generated but not used, by putting it on the utility grid.

What are the environmental benefits of the CE5?

Because the CE5 generates electricity and heat on site, the flameless conversion of hydrocarbon fuels into energy is substantially cleaner and more efficient than comparable grid-connected systems.  The CE5 provides a significant net reduction in CO2 – about one-third lighter footprint.  The system also reduces other harmful emissions produced by conventional power generation sources.  The lower carbon footprint supports the goals of California’s Global Warming Solutions Act (AB32) and other state initiatives to reduce climate change impacts.

What is ‘Tier Pricing’ and how does the CE5 address this?

California utilities charge higher per kWh rates as energy consumption rises above a certain baseline – with the top tier set at the highest rates to discourage consumption at those levels.  The CE5 reduces customer exposure to the top tier rates, saving homeowners an average of $8,000 annual in reduced energy costs, while switching much of the consumption to cleaner natural gas.

Will the CE5 interfere with the building design?

In many situations, efficiency often trump looks when it comes to being green.  With the CE5, you can offer clients both. The sleek design, compact size and color options of the unit will add, rather than deter from a building’s installed systems. Measuring 2’ (D) x 3’ (W) x 5’ (H), the CE5 fits either in an inside mechanical room or outside the home or business, discreetly sited to fit any building's design.

Will the CE5 help with Title 24 compliance?

All municipalities have different requirements for building permitting and codes.  Check with your local municipality to determine code compliance requirements, or contact one of our Sales Engineers for more information.

What is the long-range potential for Combined Heat & Power (CHP) Fuel Cells?

ClearEdge Power represents a fundamental shift in the sourcing of energy.  Ultimately, networks of micro-CHPs will be deployed within communities and business parks to provide self-generated base load energy, centrally controlled to send unused electricity back into the overtaxed grids as peak power on demand. This "distributed" approach secures and increases power generating capacity without adding new power plants and transmission lines.
