INSIGHT: US LNG export projects slate parallels cracker plans

A natural gas flareNEW YORK (ICIS)--As you look over the impressive list of planned projects for North American liquefied natural gas (LNG) exports, it’s hard not to see a parallel in the heavy project slate for planned new world scale crackers in the US. Both are being driven by the US shale gas boom. Yet there is the potential for one to threaten the other.

Unlimited US LNG exports could create volatility in natural gas and natural gas liquids (NGLs) prices, contends US-based Dow Chemical.

While LNG exports for fuel would consist primarily of dry gas where, in the process, NGLs are stripped out, LNG containing ethane and propane could be shipped out as well, according to the company.

“It is not a given that NGLs will always be stripped out prior to shipping,” says Kevin Kolevar, vice president of government affairs and public policy at Dow.

“For example, Japan has specs for wet gas concentrate in LNG. And to what extent would other countries look to use wet gas? We have not heard assurances from the oil and gas community that they would strip out the NGLs.”

This is an important aspect for the chemical sector – one that will continue to be explored. There’s an argument that LNG exports could actually increase NGL supplies, precisely because the NGLs are stripped out.

Dow contends that it supports LNG exports but is concerned that an unchecked level of exports could drive up prices and volatility in gas and NGLs. “The fact that so much capacity is being planned to come on in a compressed timeframe causes concern,” said Kolevar.

“It is all about predictability. In the late 1990s, we saw tremendous volatility in natural gas prices, which deterred investment in the chemical sector,” he added.

Dow estimates that over a 10-year timeframe, the US could export up to 5-6bn cubic feet/day (bcf) of natural gas through LNG without disrupting the market if that capacity comes on in a linear fashion.

That would amount to 38-46m tonnes/year of LNG. Yet, there is a total of 199.5m tonnes/year of LNG export capacity being planned in the US, according to an ICIS analysis. And of that amount, 128.6m tonnes/year of capacity are associated with projects with defined completion dates between 2015 and 2018.

There is virtually no chance this comes on in a disciplined, linear fashion – neither will the wave of new world scale ethane crackers. It’s simply not the nature of capital intensive businesses.

Of course not all of the planned capacity will be built. And even for those projects that do start up, LNG shipments will not always be at full capacity. This will all depend on market conditions and competitive dynamics at home and abroad.

Kolevar said Dow does not oppose LNG exports to countries that have free trade agreements (FTAs) with the US, but advocates limiting exports to non-FTA countries such as Japan – a huge importer of LNG.

So far, the US Department of Energy has approved 19 applications to export LNG to FTA countries, and only one for exports to non-FTA countries – that of Cheniere Energy’s Sabine Pass Liquefaction project in Louisiana. There are 16 other applications for these non-FTA exports under review.

On 6 February, The American Chemistry Council (ACC) clarified its position on US LNG exports, just weeks after removing a statement on its website on 24 January supporting LNG exports.

“The Executive Committee unanimously expressed its opposition to any new export bans or restrictions on liquefied natural gas such as a moratorium on export terminals or the prohibition on the export of natural gas produced on public lands," said the ACC in a statement.

"The Executive Committee also reaffirmed its support for free-market policies that promote the export of American-made goods, including the export of liquefied natural gas," it added.

However, the ACC acknowledged that "there is not a clear consensus among the membership on the question of whether the Natural Gas Act’s 'public interest' requirement should be further defined in export permitting to non-FTA countries".

The ACC is now establishing a senior level committee to further discuss this issue and see if consensus can be reached.

The US Department of Energy (DoE) notes on its website that “federal law generally requires approval of natural gas exports to countries that have a free trade agreement with the United States”.

However, for non-FTA countries, the DoE “is required to grant applications for export authorisations unless the Department finds that the proposed exports ‘will not be consistent with the public interest’. Factors for consideration include economic, energy, security and environmental impacts."

Japan is one major country with which the US does not have an FTA. Japan is also a major importer of LNG for its fuel needs. In 2012, Japan’s LNG imports jumped 11.2% to a record 87.3m tonnes.

It’s important to remember that the chemical industry is not the only group seeking to take advantage of cheap US natural gas prices.

Along with LNG projects, other major draws on natural gas will come from utilities in the form of gas-fired power plants, as well as fertilizer projects.

Meanwhile, the US petrochemical sector is planning seven new world-scale crackers and expansions of existing facilities for a total of 10.2m tonnes/year of additional ethylene capacity. This represents a whopping 38% of existing US capacity.

And speaking of parallels between the rash of planned US crackers and LNG export facilities, one LNG export project website struck a common theme – “thousands of jobs and billions of dollars invested”.
