NG Advantage to Provide Compressed Natural Gas via “Virtual Pipeline” to International Paper in Ticonderoga, NY

Service Is the Highest Volume Use of Trucked CNG to Date in the US

NG Advantage LLC – a Clean Energy company (NASDAQ: CLNE) - announced that it has signed a contract to work with International Paper (NYSE: IP) to deliver compressed natural gas (CNG) to International Paper’s Ticonderoga, N.Y. mill.

NG Advantage will deliver CNG to the mill using its Virtual Pipeline which consists of compressor stations located on natural gas pipelines, a fleet of specially designed carbon fiber CNG trailers, and off-loading and monitoring equipment which NG Advantage is installing at the mill. Deliveries will begin in May of 2015.

International Paper initially awarded this contract to NG Advantage in order to begin using natural gas prior to the completion of a planned natural gas pipeline. However, as previously announced, International Paper decided to cancel the pipeline project for cost reasons.

Despite the cancellation of the project to deliver natural gas to the mill by constructing a pipeline under Lake Champlain, contributing to a cleaner environment and reducing fuel costs remain very important to International Paper. The company has issued a new RFP for a long term trucked-CNG contract, starting when the current contract with NG Advantage ends. NG Advantage is a bidder for the long term contract as well.

The mill is currently International Paper’s largest US plant without access to natural gas. In order to meet this huge demand safely and reliably, NG Advantage has invented the “Private Virtual Pipeline”, a high volume variant of the Virtual Pipeline service, which the company introduced to the US market in March of 2013. Tractors and drivers will be based in Ticonderoga, NY – where the mill is - and gas can be provided from any of several compressor stations used by NG Advantage.

Clean-burning North American natural gas is expected to displace at least 32,000 gallons of fuel oil a day during this contract. The gas will be used to run the mill’s kiln and power boiler.

NG Advantage’s CEO Tom Evslin said “Because International Paper is staunchly committed to their environmental goals, they have done years of design work to extend a pipeline under Lake Champlain to replace fuel oil with natural gas. They will now be able to convert to burning natural gas even though the pipeline extension proved uneconomical. We are proud to use our equipment, technology, and experience to deliver the economic and environmental benefits of natural gas using our “Private Virtual Pipeline” to the Ticonderoga mill and to contribute to the economy of that region.”

NG Advantage was the first company to deliver compressed natural gas to industrial customers in the United States and is the US industry leader in volumes delivered. It is a US based mid/downstream company which currently trucks CNG to 22 large industrial and institutional customer sites in New England and New York State. With its majority investor, Clean Energy Fuels, NG Advantage is expanding its coverage area nationwide in 2015.
