ClearEdge Power is reporting that residential fuel cells are a good alternative to solar panels for onsite power because they take less space, don’t depend on sun exposure, and, as a combined heat and power product, are efficient. Its fuel cell is 40% efficient in converting fuel into electricity and 50 % efficient in heat.
Stationary fuel cell makers, including Bloom Energy and FuelCell Energy, focus mainly on business customers. But ClearEdge Power is targeting its unit, about the size of a refrigerator, to both homes and small businesses. The company has sold about 200 units in California, with more than half of the fuel cells installed in 34 California businesses, according to a representative.
The price for a five-kilowatt unit is $56,000 before installation. ClearEdge Power is initially marketing to consumers in California, who receive up to $17,500 per five-kilowatt unit in financial incentives from utility rebates and federal tax credits. Commercial customers can get as much as $27,500 in incentives, according to the company.
The fuel cell runs on natural gas, which is “reformed” and passed through a fuel cell, generating both electricity and heat. In addition to five kilowatts of electricity, one unit can generate 20,000 BTUs of thermal heat an hour at 150 degrees Fahrenheit.
More commercial customers are using fuel cells because they provide reliable power. Fuel cell companies are primarily marketing products in states which have incentives for cleaner sources of energy.
