In turn, the manager of Ecopetrol talked about its partnerships with the supply chain in the NGV sector. “It is a trust fund system for generating demand. We work on the quality of the conversions and on a competitive market price, and we offer a cost effective scheme for the entire chain and benefits for users,” he said. He also explained the LNG market is still incipient in Colombia, but highlighted trucks as the main target, with 50,000 vehicles currently running on diesel, and revealed that they are already preparing pilot tests with other chain actors. Villa also said it is necessary to develop fueling infrastructure, build liquefaction plants and venture into mobile pipelines.
The second speaker was Henri Tarbouriech, who discussed about “Cryostar Application for Liquid Natural Gas in the Vehicle Industry”. The South American representative of the French company focused on their various LNG-related projects. Besides emphasizing the fuel competitive advantages compared to diesel, he described the different types of LNG (cold, saturated and supersaturated) and further explained the operation of an LCNG station. “It doesn’t take as much energy as a CNG facility, offering more benefits, such as improved energy efficiency and less hard maintenance. We also have new equipment to meet the demand,” he said.
He also spoke about the LNG dispensers they manufacture, which have a capacity of 160 liters per minute and can supply 10 vehicles per hour. “Cryostar offers a control program that lets you supervise the tank, pump and the entire system, with remote control from a maintenance center”, said Tarbouriech as it is another of his company’s services and eventually provided a list led by Sweden with all stations they have implemented in the world.
On behalf GNC Galileo, Del Campo addressed “New Technologies for the Production and Transmission of Gas: LNG, Wellhead Compression and Virtual Gas Pipeline”. “We designed an LNG solution, the natural gas version that may be more widespread and standardized in high horsepower applications,” said the Argentine businessman regarding Cryobox system. Galileo CEO explained that while CNG is ideal for short distance and is an irreplaceable fuel already tested around the world, it cannot provide solutions to heavy-duty vehicles, long haul trucking, trains or the maritime system. He added that the “Transported LNG” model, popular in the 70s, is not a system that can be massive since plants producing LNG are restricted to areas close to gas sources, which require complex logistic and high investments and operative costs.
In this sense, Del Campo provided more details of the technology developed by Galileo, which already services Buquebus ferry operating between Buenos Aires and Montevideo. The Cryobox unit produces LNG as closed as possible from the users, is easy to install and maintain. It is also modular, scalable and capable to be relocated, without sacrificing power or efficiency. “Cryobox is a real product, it is a system based on an existing platform, the Microbox, and produces LNG in the same way that a filling station produces CNG,” he added.
