Taken together, the ethane-related infrastructure projects developed in the U.S. over the past several years serve as a reliable feedstock-delivery network for a number of steam crackers in Europe, Asia, and Latin America. NGL pipelines transport y-grade to fractionation hubs, fractionators split the mixed NGLs into ethane and other “purity” products, ethane pipelines move the feedstock to export terminals fitted with the special storage and loading facilities that ethane requires, and a class of cryogenic ships — Very Large Ethane Carriers, or VLECs — sails ethane to mostly long-term customers in distant lands. The end results of all this development are virtual ethane pipelines between, say, the Marcellus/Utica and Scotland, or the Permian and India. Today, we continue our series on ethane exports with a look at the two existing export terminals, the ethane volumes they have been handling, and where all that ethane has been headed.

The run-up in U.S. production of natural gas liquids over the past 10 years spurred the development of a whole lot of infrastructure. More pipelines to transport mixed NGLs from production areas to NGL storage and fractionation hubs, especially Mont Belvieu, TX. More fractionators to split y-grade into ethane, propane, and other “purity” products. And, specifically for ethane — the lightest, quirkiest, and most plentiful NGL — a number of ethane-only steam crackers were built along the Gulf Coast to take advantage of the new supply abundance, as were ethane-only pipelines, export terminals, and a whole new class of cryogenic ships — Very Large Ethane Carriers, or VLECs — to move the product to markets in Europe and Asia. Today, we begin a new series on the unique nature of overseas ethane exports, including why most incremental export volumes are tied to long-term supply deals with a handful of global ethylene plants designed — or reconfigured — to “crack” ethane.

U.S. ethane exports have risen steadily over the past five years, from next to nothing in early 2014 to an average of 255 Mb/d in 2018 and 269 Mb/d in the first three months of this year. But unlike its heavier NGL siblings propane and butane, which are in demand globally as fuels and feedstocks, ethane’s only established use is in steam crackers specifically equipped to process it, so there are only a few countries where exported ethane is likely to end up. Also, the waterborne transport of ethane is generally limited to specially designed ethane carriers, and there aren’t many of those around because of ethane’s restricted market. All this makes for an export commodity that stands apart. Today, we review the evolution of U.S. ethane exports and the challenges to export growth posed by the U.S./China trade war.

The Houston Ship Channel (HSC) is one of the busiest shipping lanes in the U.S. Each year, thousands of vessels utilize the waterway, importing and exporting goods ranging from pharmaceutical products to what the Census Bureau classifies as “Leather Art; Saddlery Etc.; Handbags Etc.; Gut Art”. More to the point of today’s blog: over 10 million tons of energy products move through the channel each month. But as ships grow ever larger, the ports and canals that service them must also adapt to be able to handle their increased dimensions. The Houston Ship Channel now finds itself in a situation where it must adapt to meet increasing market demands. Today, we continue our series on the issues facing some Texas ports and the measures being taken to help alleviate them.

In terms of raw tonnage, the Port of Houston is by far the busiest in the United States. The 52-mile-long Houston Ship Channel (HSC) — running from just outside downtown Houston out to an area between Galveston Island and Bolivar Peninsula — is the artery that enables the heavy ship traffic, much of it tied to crude oil, LPG, petroleum products and other hydrocarbons. But in the same way that Houston’s Interstate 45 traffic backs up during the morning commute, the ship channel traffic, which normally runs at about 60% of peak levels, can be (and has been) subject to delays when there’s an accident, visibility problems, or a slow-moving double-wide taking up two lanes. With energy-related export activity on the rise, efforts are underway to address those issues. Today, we begin a series on the issues facing some Texas ports and the measures being taken to help alleviate them.

The U.S. started exporting ethane by ship less than three years ago, first out of Energy Transfer’s Marcus Hook terminal near Philadelphia and then from Enterprise Products Partners’ Morgan’s Point facility along the Houston Ship Channel. Good news for NGL producers, right? Well yes, sort of. Because while waterborne export volumes rose through 2016, 2017 and the first seven months of last year, they’ve been flat-to-declining ever since, with further ethane-export growth hampered primarily by a lack of international demand. That demand may soon be ratcheting up — mostly in China, but also in Europe — but it won’t happen overnight. Today, we discuss ethane export trends, the Morgan’s Point and Marcus Hook marine facilities, and plans for new ethane export capacity tied directly to new overseas ethane crackers.
