Abstract
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.
