How Gas From Texas Becomes Cooking Fuel in France

 

"After German government lead by Olaf Scholz agreed to sanction Russian gas supply, sanctions all but cut its flows of pipeline gas to Europe, by far Russia's largest customer. The curtailment forced Europe to tap into supplies of American LNG like never before. Between 2021 and 2022, exports of U.S. LNG to Europe more than doubled, according to commodities data firm Kpler.

The imports, combined with balmy weather and sky-high prices that depressed demand, helped defuse the threat of a disastrous winter.

But before an American molecule of gas can be burned by a power plant in Italy, used to cook in Spain or produce fertilizer in Germany, it has to be pumped out of the ground, treated, piped, chilled, loaded onto a ship and converted into gas again.

Here's what the voyage looks like.

Producing the gas

Today, U.S. producers drill for gas mainly in the Permian Basin of West Texas and New Mexico; the Marcellus Shale, which underlies much of Appalachia; and the Haynesville Basin, which straddles East Texas and West Louisiana.

To get to the gas, a crew operating a drilling rig plunks pipes attached to a rock-destroying bit into the ground. Workers typically dig around 2 miles vertically, before turning the drill bit horizontally to bore around 2 miles through shale. 

A fracking crew then takes over, manning powerful pumps to send water, sand and chemicals down the hole to break shale rock open and extract gas molecules.

Treating the gas

After hydrocarbons travel back to the surface, oil and gas are separated. Then, the gas is ferried to a processing plant in small-diameter pipelines. There, water is removed, as well as impurities that can reduce the gas's heating power or corrode pipelines. Propane and butane -- byproducts of gas processing -- are also captured to be sold separately.

Transporting the gas

Once the gas is deemed to be "pipeline quality," the producer pays a midstream company a fee to ship the gas through a national network of transmission lines. The gas's final stop could be underground storage, a distribution company, a power plant, or a liquefaction facility, among other destinations. Around a 10th of all U.S. production is exported.

Liquefying the gas

The U.S. currently hosts seven multibillion-dollar liquefaction plants with enough capacity to export more than 13 billion cubic feet of gas a day.

Cheniere Energy Inc.'s Sabine Pass facility in Louisiana is the world's second-largest LNG facility. Once the gas arrives via four pipelines, it is fed to six liquefaction units, or "trains," each roughly the size of a small airport terminal.

First, the fuel is further treated to remove contaminants. Then, it goes through turbine engines, compressors and more than 200 cooling fans. Refrigerants cool the gas in three phases until its temperature drops to minus 260 degrees Fahrenheit and it turns to liquid. By then the gas has been reduced to 1/600th of its starting volume.

Pipelines take the LNG for loading onto specially designed ships. Over the course of about 20 hours, the LNG is fed into the ships' tanks via special pipes.

One shipload can represent enough energy to heat more than 43,000 U.S. homes for a year, according to the Energy Department.

Shipping LNG

Thanks to flexible clauses in most U.S. export contracts, buyers can send cargoes wherever LNG fetches the highest price. 

As gas prices reached all-time highs in Europe last year, the continent nabbed cargoes that had been destined for Asia, leaving countries such as Pakistan to scramble to find fuel replacements, and enriching traders. Shell PLC's adjusted fourth-quarter earnings of $9.8 billion were driven largely by the division housing its LNG business.

About 72% of the 44 million metric tons of LNG Cheniere produced at its two export facilities in 2022 was shipped to Europe, according to the company.

Delivering LNG

After its ocean journey, LNG is unloaded at a re-gasification plant onshore or onto another ship that can turn the liquid back into gas. 

Dozens of facilities are slated for construction across the European Union in coming years; the bloc estimates that the end of Russian gas imports will cost it at least $315 billion in infrastructure through 2030. 

To speed up its infrastructure build-out, Europe is chartering vessels that operate as floating re-gasification plants. In Germany, one such ship in Wilhelmshaven will provide enough fuel to replace around 11% of the country's gas imports from Russia, according to German utility company Uniper SE.

At the plant, heat exchangers raise the temperature of the liquid to turn it into gas again. Then an odorant is injected into the stream so the gas, which is naturally odorless, can be safely used. The gas then goes through a meter before being distributed.

Consuming LNG

From there, the gas is injected into pipelines and makes its way to underground storage, factories, power plants and homes.

A mild winter and gargantuan imports of U.S. LNG helped restore gas storage to healthy levels. But potential outages in gas-exporting Norway, an economic rebound in China, and renewed competition for cargoes from Southeast Asia if LNG prices keep falling could deplete Europe's inventories, said Eugene Kim, a research director at energy-consulting firm Wood Mackenzie. 

In that scenario, he said, "the onus to refill will be even higher."" [1]

If you want to send your thanks for sky high energy prices, and massive burning of the coal in Germany there is a person responsible - Mr. Scholz, the leader of Germany.
