Gulf Coast

Many of the natural gas storage projects under development along the Gulf Coast involve the expansion of existing salt-cavern complexes and, with that, the sharing of at least some already-built infrastructure. That typically saves money, and the lower capital costs can help make a project a “go.” But at least a few well-sited projects competing for commitments are greenfield in nature and require not just the buildout of storage capacity itself but also the development of compression, freshwater wells, saltwater disposal wells, electricity supply, header pipelines and pipeline interconnections. In today’s RBN blog, we discuss two of the largest greenfield projects in the works: the Black Bayou Energy Hub in southwestern Louisiana and the Freeport Energy Storage Hub (FRESH).

As a group, Texas, Louisiana, Mississippi and Alabama have more than 1.1 trillion cubic feet of natural gas storage capacity, most of it along — or within easy reach of — the Gulf Coast, with its long-and-growing list of LNG export terminals as well as gas-consuming industries and gas-fired power plants. That’s a good thing, but still more gas storage will be needed to help ensure there is sufficient gas in hand to meet the region’s rising — and increasingly volatile — requirements. In today’s RBN blog, we’ll continue our review of Gulf Coast storage projects with a look at plans by Trinity Gas Storage and Caliche Storage.

Storms that form in the Gulf of Mexico (GOM) during hurricane season don’t just dissipate once they make landfall and can inflict havoc on onshore assets. Storm damage and flooding can delay plant restarts, but so can power outages, as we saw when Hurricane Beryl hit the Texas/Louisiana region in July. And while there were no major refining or production assets in the path of Hurricane Helene, which slammed into the Florida Panhandle on September 26, widespread damage illustrated the potential risk to onshore infrastructure. In today’s RBN blog, we will examine how hurricanes have disrupted onshore assets and explain why power restoration is often the Achilles’ heel in plans to resume normal operations.

Very little new natural gas storage capacity has been built along the Gulf Coast the past few years, but that’s changing. Driven by rising demand from power generators, LNG operators/offtakers, marketers and traders for storage with high deliverability rates — and by improving storage economics — new salt-cavern and depleted-reservoir capacity is now being developed by midstream players large and small, with plans for a lot more. In today’s RBN blog, we‘ll continue our review of gas storage projects in Texas, Louisiana and Mississippi with a look at what Kinder Morgan, EnLink Midstream and Enstor Gas have been up to.

Fast-changing dynamics in Gulf Coast natural gas, electricity and LNG export markets are increasing the value of gas storage in Texas, Louisiana and Mississippi — or, more specifically, the merit of quickly injecting and withdrawing gas to respond to market swings. As a result, interest in developing gas storage projects with high “deliverability" rates has taken off, with billions of cubic feet of new storage capacity already coming online and a lot more in the works. In today’s RBN blog, we’ll begin a look at why so many market participants — power generators, LNG operators/offtakers, midstreamers, marketers and traders — are chasing the “extrinsic” value of gas storage and where the new storage projects are being built.

The Houston crude oil hub has become busier over the last few months, and if one or more proposals to build a deepwater export terminal nearby capable of fully loading a Very Large Crude Carrier (VLCC) cross the finish line, it could become the hub supplying them. That could push Permian Basin oil flows on Houston-bound pipelines higher at the expense of flows to Nederland and Corpus Christi. In today’s RBN blog, the third in a series, we will examine the latest Permian oil flows to Houston and how that could change if and when a deepwater project comes online. 

In the race to build the next deepwater crude oil export terminal in the Gulf of Mexico, Sentinel Midstream’s proposed Texas GulfLink (TGL) is currently in second place in the regulatory race, behind only Enterprise’s Sea Port Oil Terminal (SPOT) — and seems to be emerging as a serious contender. The plan offers some compelling attributes, including Sentinel’s status as an independent midstream player and plenty of pipeline access to crude oil volumes in the Permian and elsewhere. In today’s RBN blog, we turn our attention to TGL and what it brings to the table. 

The deepwater crude oil export projects under development along the U.S. Gulf Coast offer a number of potential benefits to shippers and customers alike. These include the ability to fully load a Very Large Crude Carrier (VLCC) and the economies of scale that come with that, the elimination of reverse lightering and the corresponding decrease in emissions, and freed-up access on congested ship channels for other exports such as NGLs, refined products and clean ammonia. So, given all the potential upside, why hasn’t anyone fully committed to building one? In today’s RBN blog, we focus on the obstacles faced by deepwater export facilities and where each of the projects under development is in the permitting process. 

Thanks to expanding heavy crude oil production in Western Canada’s oil sands in recent years and increased pipeline access from the region to the U.S. Gulf Coast, re-exports of Canadian heavy crude from Gulf Coast terminals set a record in 2023. With additional production gains on tap in the oil sands, it might seem natural to think that another re-export record is in the works for 2024. However, assuming the much-delayed Trans Mountain Expansion Project (TMX) does indeed start up this year — offering a vastly expanded West Coast outlet for oil sands production — last year’s re-export high might end up being a peak, at least for the number of years it takes for growth in Western Canadian heavy crude production to exceed the capacity of the TMX expansion. In today’s RBN blog, we take a closer look at TMX’s likely impact on Gulf Coast re-exports. 

Crude oil, natural gas and NGL production roared back in 2023. All three energy commodity groups hit record volumes, which means one thing: more infrastructure is needed. That means gathering systems, pipelines, processing plants, refinery units, fractionators, storage facilities and, above all, export dock capacity. That’s because most of the incremental production is headed overseas — U.S. energy exports are on the rise! If 2023’s dominant story line was production growth, exports and (especially) the need for new infrastructure, you can bet our blogs on those topics garnered more than their share of interest from RBN’s subscribers. Today we dive into our Top 10 blogs to uncover the hottest topics in 2023 energy markets. 

We’ve reached the two-year anniversary of the reversal of the joint-venture Capline crude oil pipeline. With its current north-to-south flow, it adds to the few conduits that can move oil from the Midwest to the Gulf Coast, specifically the St. James, LA, oil hub. Flows have been on a steady climb since southbound service began in December 2021, but volumes appear to be short of its available capacity, and there are looming headwinds. In today’s RBN blog, we examine whether Capline’s flows could be affected by the impending startup of the Canadian government-owned Trans Mountain Expansion Project (TMX). Could rising Alberta production be its golden ticket?  

Storage has long been a critically important balancing mechanism in the Lower 48 natural gas market. Now, after languishing for much of the Shale Era, storage values are coming out of the doldrums. The key driver behind this change is that, unlike in the old days, when the storage market was driven primarily by the intrinsic value of capacity — i.e., the need to sock away gas in the lower-demand summer months for use in the peak winter months — the value of storage is being driven almost exclusively by extrinsic economics — i.e., how flexible and responsive capacity allows market participants to manage supply and demand during short-term market swings. This flexibility and responsiveness have become increasingly important criteria for ensuring reliability as LNG export facilities and an increasingly renewables-heavy power sector navigate frequent demand fluctuations day to day, or even intraday, as well as during high-stakes, extreme weather events like 2021’s Winter Storm Uri. In today’s RBN blog, we delve into the fundamental shifts influencing today’s storage market. 

LNG feedgas demand has averaged a record of about 12 Bcf/d this summer and fall. While that may sound like an impressive number (and it is), it could increase significantly — even without new capacity additions — over the next few months as seasonal demand rises and maintenance activity slows. And that’s just for starters. Next year, the first of several planned LNG export terminals and expansions of existing ones will start commissioning, and by the end of this decade feedgas demand may well double. In today’s RBN blog, we look at how current LNG feedgas demand stacks up compared to past years, the factors driving current demand, and the potential for additional upside.

When you’re in competition for billions in federal dollars, you need more than just a sensible approach and a strong economic case. You need a real competitive advantage. That’s what Hy Stor Energy believes it has with its proposed Mississippi Clean Hydrogen Hub (MCHH). It sees off-the-grid renewable power and extensive salt-dome storage capabilities as the surest path to decarbonization for a myriad of industrial needs. In today’s RBN blog, we look at the overall strategy behind the MCHH, the plan to produce 100% green hydrogen, and how Hy Stor hopes to beat the competition and secure Department of Energy (DOE) funding for a regional hydrogen hub.

Enterprise Products Partners doesn’t just extract mixed NGLs from associated gas at processing plants, transport that Y-grade to the NGL hub at Mont Belvieu, and fractionate NGLs into “purity products” like ethane, propane and butanes. The midstream giant also distributes purity products to Gulf Coast steam crackers and refineries, converts propane to propylene at its two propane dehydrogenation (PDH) plants, distributes ethylene and propylene, transports propane and butane to wholesale markets across much of the eastern half of the U.S., and exports a wide range of products — ethane, LPG, ethylene and propylene among them — from two Enterprise marine terminals on the Houston Ship Channel. (Another export terminal in Beaumont, TX, is in the works.) Talk about a value chain! In today’s RBN blog, we continue our series on NGL networks with a look at Enterprise’s NGL and petrochemical production, distribution and export assets.
