Heat-to-power generator to capture waste heat in the US Midwest

24 March 2010 – The new Michigan-based energy solutions company ProRenewables, in conjunction with Kalamazoo Valley Community College, has introduced the ‘Green Machine’, an innovative, clean energy technology from Nevada-based ElectraTherm Inc, which employs water to produce emission-free electricity from waste heat.
ProRenewables intends to deploy ElectraTherm’s heat-to-power generator to industry throughout the US Midwest to capture available waste heat.
The Green Machine is the most economically-viable technology for capturing waste heat to produce electricity in the global marketplace, says ProRenewables.
The technology enables industrial customers to substantially increase energy efficiency, reduce consumption of costly fuel and decrease emissions. Employing a robust twin-screw expander in place of turbine technology results in low maintenance outlay over the life of the machine, and its compact footprint makes the device modular and scalable.
ProRenewables, a joint venture launched by investment management firm the Windquest Group, and ProServices, a specialized trade contractor, will sell, install and maintain the Green Machine to support industry throughout that states of Michigan, Illinois, Indiana, Ohio, Kentucky, West Virginia and Pennsylvania.
The Midwest is said to be an ideal location for recovered energy generation, given the region’s factories, power plants, paper and steel mills, food processing facilities and other heavy industry.
Approximately two-thirds of the fuel burned to generate power in the US, and up to half of industrial energy consumption is lost as waste heat, and deployment of an energy efficient, emissions-free generator should lower costs and increase the Midwest region’s industrial competitiveness.
The payback period at most installations ranges from two to five years, depending on cost of installation relative to electricity rates and available financial incentives, says ElectraTherm.
While the company has shipped Green Machines for applications employing solar thermal, industrial, boiler, and geothermal heat, the latest demonstration unit at the community college’s Michigan Technical Education Center is the first installed in Michigan and the Midwest.
