Energy Recovery Generation (ERG®)
Many industrial processes exhaust significant quantities of waste energy as a by-product of operations. The ERG® process captures this energy resource through the use of proven heat recovery technology and converts it to usable electrical energy. This generation results in no incremental emissions while providing electrical energy and dependable capacity into the electrical system. The current focus of Pristine's ERG® program involves existing third party owned gas turbine-driven compressors utilized in long-haul gas pipelines. These projects range in size from 3 to 12 MW in capacity and offer the potential to deliver cost-effective and reliable energy with no or minimal incremental emissions.
ERG® relies on the flow of hot exhaust gases that are otherwise wasted through venting to the atmosphere.
ERG® projects involve zero to minimal incremental air emissions and are expected to have the potential to create GHG emissions offset credits while reducing operating costs to the compressor operator. It is not yet known at this time whether ERG® will be able to generate offset credits, as the Government of Canada has not yet finalized its proposed emissions trading system.
Pristine is currently constructing two 5 MW ERG® projects on a long-haul natural gas pipeline, being the Enpower Projects.
