How does natural gas transportation work? When compressed to 3,600 psi, compressed natural gas, or CNG, can function as an alternative to gasoline, boasting improved power, acceleration, and reduced greenhouse gas emissions. Furthermore, CNG is economically feasible. With increased US supply, owing to recent shale and drilling discoveries, the price of natural gas has dropped 70% over the last five years.
The team, comprised of Brandon Koster, Karl Bratt, and Jonathan Haines, are currently constructing such a system. To ensure heat dissipation and simplicity, the team developed its design around a two-stage hydraulic cylinder compression system. This design, composed of one double-acting hydraulic cylinder, minimizes floor space and overall cost. For reliability, the system’s manifolds and compression cylinders were constructed from cold worked steel, guaranteeing strength and stability. For safety, the system is controlled with input, output, and thermocouple modules affixed to monitoring software. The estimated market price of such unit is under $3,000, far less than the competition.
Overall, team NaturaFill believes that transitioning domestic energy consumption away from imported oil, in favor of cleaner, American natural gas, is vital for long term economic, environmental, and political stability. The team desires that, in some small way, they have helped in carrying out that mission.
