Alphabet Energy is the global leader in thermoelectrics for waste heat recovery.

With over 60 patents issued and filed, Alphabet Energy is the first company to leverage breakthrough thermoelectric materials advances for a modular, scalable approach to waste heat recovery, delivering both PowerModules™ and turnkey thermoelectric generators such as the E1™ .

PowerBlocks™, the first low-cost, efficient thermoelectric for power generation

PowerBlocks™, the first low-cost, efficient thermoelectric for power generation

Thermoelectric materials generate electricity while in a temperature gradient. Our core thermoelectric materials called PowerBlocks™ employ the first low-cost, highly efficient thermoelectric materials: silicon or tetrahedrite. PowerBlocks™ are the first thermoelectrics to use light elements which are abundant and low cost. PowerBlocks™ have been tested by third parties and verified to be the most efficient thermoelectric materials ever made for waste heat recovery.

Modular Thermoelectric Technology

Modular Thermoelectric Technology

PowerBlocks™ are assembled into PowerModules™ that generate power from an exhaust source. PowerModules™ include proprietary hot- and cold-side heat exchangers, advanced interfaces and highly specialized geometries. They are strong, reliable, and the first and only upgradable thermoelectric modules. As theremoelectric materials advance, PowerModules™ in existing generator systems can be upgraded to include higher-performing, next-generation thermoelectric materials.

Alphabet Energy's Turnkey Thermoelectric Generators

Turnkey Thermoelectric Generators

Alphabet Energy offers the only turnkey thermoelectric generators for waste heat recovery that generate reliable remote power while also reducing fuel consumption, operating costs and carbon emissions. Our generator systems are designed to provide reliable 24/7 performance in the world’s harshest operating environments. Because thermoelectrics are steady state, our generator products require no engine modifications, no working or compressor fluids and virtually no maintenance. They also are easy to install and relocate between sites.
