U.S. Shale Revolution Transforms the Global Gas Market

Or perhaps more accurately, American shale gas is helping to create a global gas market.

For years, natural gas needed pipelines to make its way from seller to buyer, and owing to that, most natural gas contracts were long-term and often linked to the price of oil. But thanks to liquified natural gas, suppliers can now superchill gas and put it on cargo ships to send halfway around the world, making the gas market more like that of its kindred hydrocarbon, oil. As a result, the differences between regional LNG prices has begun to narrow—the so-called “Asian premium,” more than 50 years old, is starting to evaporate. American shale gas is ready to expedite this transition to a more fungible, global gas market, as Bloomberg reports:

[The] global LNG titans gathering in Tokyo this week for Gastech are in the midst of the biggest shakeup since the industry was founded in the 1960s. Just as American crude is increasingly making its way to Asia, the world’s biggest oil market, the burgeoning armada of gas cargoes from the U.S. and elsewhere are poking holes in the financial system on which the industry’s multi-billion plants are funded.

“As U.S. exports ramp up, we’re going to see even more flexibility with more people trying to buy and trade volumes. The old models of stable long-term contracts will really have to change,” said Zhi Xin Chong, a gas analyst for Wood Mackenzie Ltd. in Singapore. “We’ve already seen the impact of U.S. LNG on contract trends, with more destination flexibility coming into play.”

U.S. shale is also helping to get rid of destination requirements for LNG cargoes, which will allow intermediaries to buy and then re-sell LNG to the highest bidder. That will help make the market more liquid, and will reduce regional price variation as well.

In the longer term they’re hoping this e-plane research will lead to ‘hybrid-electric airliners’.

Siemens has just announced that an electric aerobatic plane powered by its latest motor has nabbed two world speed records, as New Atlas reports.

The Extra 330LE aircraft is now the fastest e-plane under 1,000 kg, and also – after a few mods – the quickest above 1,000 kg, too. The electric test plane also became the first in the world to tow a glider up into the skies.

The Extra 330LE aerobatic plane powered by the lightweight electric motor announced by Siemens in 2015 made its first flight in July 2016.

The motor tips the scales at 50 kg (110 lb) but is reported capable of delivering a continuous output of 260 kW, five time more than comparable propulsion systems.

Before the end of last year, the flying test bed had opened a new page in the record books by setting a new world climb record, winging its way up to 3,000 meters (9.840 ft) in 4 minutes and 22 seconds – a climb velocity of 11.5 meters per second.

On March 23, at the Dinslaken Schwarze Heide airfield in Germany, the Extra 330LE managed to top out at 337.5 km/h (209.7 mph) during its 3 km (1.8 mi) straight line flight, 13.48 km/h faster than the previous record set in 2013. The new record has been officially recognized by the World Air Sports Federation (in the category “Electric airplanes with a take-off weight less than 1,000 kg”).

The e-plane also clocked a new world record in the “above 1,000 kg” category with a modified configuration, achieving a top speed of 342.86 km/h (213 mph).

But two world speed records clearly weren’t enough. The day after setting the speed record, the Extra 330LE took to the skies again – this time towing a type LS8-neo glider, the first time an electric aircraft has been used for such a task. The electric flyer managed to take the glider up to 600 meters (1,968 ft) in just 76 seconds.

There are no current plans to take the test aircraft into series production, but the project collaboration with Airbus that began last April intends to develop hybrid-electric airliners based on scaled up versions of the Siemens electric motor.

*** ‘Cognitive dissonance’ is the mental stress (discomfort) experienced by a person who simultaneously holds two or more contradictory beliefs, ideas, or values; when performing an action that contradicts existing beliefs, ideas, or values; or when confronted with new information that contradicts existing beliefs, ideas, and values. As a twist on that concept, George Orwell […]
