Industrial-Scale Thermoelectric Generator Debuts

October 8, 2014 By Linda Hardesty

alphabet energy manageAlphabet Energy introduced its E1 thermoelectric generator, which attaches to an exhaust stack to capture exhaust heat and convert it into electricity. The industrial-scale thermoelectric generator is the first product introduction for the company, which was founded in 2009 at Lawrence Berkeley National Laboratory.

Thermoelectrics use a temperature differential to generate electricity in the solid state. The E1 generates up to 25 kW per 1,000 kW engine, saving 52,500 liters of diesel fuel per year, per engine. Alphabet Energy has already taken multiple orders for the E1, which it says has gone through extensive customer testing in the field.

Alphabet says the E1 meets the mining and oil & gas industries’ criteria for simple waste-heat recovery. The E1 operates with technology that has no moving parts, no working fluids and requires minimal maintenance.
