CESSFORD, Alta.—A Nevada-based renewable energy equipment said two of its heat-to-power generators running at a ConocoPhillips Co. facility in southern Alberta are producing 90 kilowatts-electric (kWe) of fuel-free, emission-free electricity.
ElectraTherm, Inc. said it installed a pair of its Green Machine 4400 generators at ConocoPhillips’ gas compression station in Cessford, Alta., east of Calgary, to run off of waste heat of a 1,400-horsepower General Electric Co. (GE) Waukesha natural gas engine.
The two Green Machines work to generate a combined 90 kWe of fuel-free, emission-free electricity at the site running off of the Waukesha’s waste-heat alone, according to ElectraTherm.
Exhaust heat from the engine is converted to hot water and added to the jacket water heat through an engine glycol cooling loop combined with an Aprovis Energy Systems GmbH exhaust gas heat exchanger.
The waste heat then enters each Green Machine at 110°C) where it’s converted into usable power.
The Green Machines are remotely monitored by ElectraTherm at its Reno, Nevada, site some 2,000 kilometres away.
According to ElectraTherm, the Green Machines at the ConocoPhillips site are the company’s first commercial units that are approved under the Canadian Standards Association (CSA) and Canadian Registration Number (CRN) deployment in Canada.
