Publication number: 20230332744Abstract: A system for storing and transporting compressed natural gas includes source and destination facilities and a vehicle, each of which includes pressure vessels. The pressure vessels and gas therein may be maintained in a cold state by a carbon-dioxide-based refrigeration unit. Hydraulic fluid (and/or nitrogen) ballast may be used to fill the pressure vessels as the pressure vessels are emptied so as to maintain the pressure vessels in a substantially isobaric state that reduces vessel fatigue and lengthens vessel life. The pressure vessels may be hybrid vessels with carbon fiber and fiber glass wrappings. Dip tubes may extend into the pressure vessels to selectively expel/inject gas from/into the top of the vessels or hydraulic fluid from/into the bottom of the vessels. Impingement deflectors are disposed adjacent to the dip tubes inside the vessels to discourage fluid-induced erosion of vessel walls.Type: ApplicationFiled: June 26, 2023Publication date: October 19, 2023Applicant: NEARSHORE NATURAL GAS, LLCInventors: Pedro T.

Patent number: 10890294Abstract: Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG). An exemplary pipeline system may include a gas supply station, a mother station for treating gaseous fuels from the gas supply station, a mobile transport system for receiving and transporting the gaseous fuels, and user site for unloading the gaseous fuels from the mobile transport system. The unloaded gaseous fuels can be further used or distributed.Type: GrantFiled: December 5, 2017Date of Patent: January 12, 2021Assignee: NEARSHORE NATURAL GAS, LLCInventors: Pedro T. Santos, Scott Rackey, Jeremy Pitts, Aaron Hilber, Kolar L. Seshasai, Pedro Vergel, Jimmy Romanos

Patent number: 10202976Abstract: A mobile compressed natural gas (CNG) vessel and unloader are used to supply CNG to a compressor during regulatory emissions testing of the compressor (e.g., U.S. EPA's Quad J testing). CNG output by the compressor is recirculated to an inlet of the unloader so that it is reused during the emissions testing. Lean CNG from the vessel may be used to power the compressor during the testing. The unloader ensures that the compressor is run at at least a predetermined load factor during the emissions testing.Type: GrantFiled: February 23, 2017Date of Patent: February 12, 2019Assignee: Nearshore Natural Gas, LLCInventors: Daniel P.
