Greenfield Ethanol Greenfield Ethanol

Greenfield Ethanol’s Tiverton (ON) operation initially used steam from a neighbouring nuclear plant for its process heating needs. When this steam supply became unavailable, they converted to boilers fuelled by heavy oil. Dissatisfied on account of operational and maintenance issues and high fuel costs, they looked to natural gas as an alternative. Without NG pipeline access, this necessitated a bulk transport solution.

Project Fact Sheet

CES Scope of Work:

  • Comprehensive feasibility study to determine operational viability and cost savings achievable with a system that delivers NG via high pressure tube trailer from a pipeline access point situated in Mount Forest
