GE will be implementing its ‘CNG in a box’ technology in the United States to help accelerate the adoption of natural gas as a transportation fuel in collaboration with Chesapeake Energy Corporation.

In March 2011, GE and Chesapeake signed a Memorandum of Understanding on a product and services development partnership, representing a multi-year collaboration between the two companies to develop and bring to market compressed natural gas (CNG) and LNG transportation, and natural gas home-fuelling solutions.

The collaboration is designed to leverage GE’s global oil and gas technology portfolio with Chesapeake’s expertise in developing innovative fuelling solutions to lower the ownership and operational costs of natural gas vehicle (NGV) fuelling stations.

CNG in a box

GE will provide more than 250 modular and standardised CNG compression stations for NGV infrastructure. These units, also known as ‘CNG in a box™’, will provide the core infrastructure to enable expanded access to CNG at fuelling stations.

The technology takes natural gas from a pipeline and compresses it onsite at an industrial location or at a traditional automotive refilling station to then turn it into CNG. A CNG vehicle, such as a taxi, bus or small truck, can then refill its tank using a traditional fuel dispenser.

The technology’s key features include:

  • The gas compression, storage, cooling, drying and controls are easy to ship and maintain due to its compact ‘in box’ design.
  • The units come in two size configurations, depending on the site’s need.
  • Its modular and intuitive design allows it to ‘plug and play’ onsite.
  • The offering includes GE Wayne-branded dispensers with credit card capability and provision for point-of-sale interface.
  • The fuel dispenses at an equivalent rate of approximately 7 gasoline gallon per minute.

The CNG technology will be brought to market by Peake Fuel Solutions, a Chesapeake affiliate.

“A vehicle using CNG can reduce annual fuel costs by up to 40 per cent, assuming 41,360 km per year driven, gasoline priced at $US3.50 per gallon and CNG at $US2.09 per gasoline gallon equivalent,” said GE.

“This represents savings totalling as much as $US1,500 per fleet vehicle per year. In total, for each fleet vehicle using fuel provided by ‘CNG in a box’ instead of gasoline, a fleet operator can reduce CO2 equivalent emissions from fuel combustion by approximately 24 per cent, or 2.2 tonnes per vehicle annually, assuming an average fleet vehicle travels approximately 41,360 km per year.”
