In the following video, Motley Fool energy analyst Joel South tells investors about one pipeline company he's very bullish on, Boardwalk Pipeline Partners (BWP). He tells us about this company's 14,300 miles of natural gas pipeline and 11 storage facilities, which are rare in the industry because the storage facilities are naturally occurring spend aquifers and salt caverns, which help widen Boardwalk's competitive moat . Also, the company's toll-based business model guarantees reliable cash flow, and it has relatively cheap access to capital compared to other players in its industry, which will be vital for growth in the coming years.
