Germany races to stockpile gas before winter

Germany’s race to stockpile gas ahead of the winter is taking place in the Bavarian Alps.

Germany races to wean itself from Russian energy and stockpile enough gas before winter is taking place in the foothills of the Bavarian Alps, 1,600 metres (one mile) below ground.

The former Bierwang natural gas field in Unterreit, surrounded by rolling farmland near the banks of the Inn, operates as one of Germany’s largest underground gas storage facilities.

Run by German operator Uniper, Bierwang can hold more than 800 million cubic metres of gas — enough to power the nearby city of Munich for eight months.

Like other storage sites, Bierwang replenishes its stocks between winters, to keep homes heated and Germany’s energy-hungry industry humming during the cold months when demand is highest.

But this year, the stakes are higher than ever.

With the war in Ukraine raging and Moscow increasingly seen as an unreliable supplier, governments across Europe are scrambling to store supplies before Moscow decides to reduce the flow of gas or close the taps altogether.

“The security of supply this winter will depend on two factors: how full the storage facilities are and how much new gas keeps arriving” from abroad, said Sebastian Herold, a professor of energy economics at the Darmstadt University of Applied Sciences.

Russian deliveries will play a “decisive role” in this, Herold said.

Efforts by successive German governments to build closer economic ties with Moscow have left the country hooked on Russian energy imports, a policy now widely seen as misguided.

Fears that a sudden shortage of Russian gas could bring Europe’s biggest economy to its knees recently prompted the German government to adopt legislation requiring all of the nation’s gas reservoirs to be 90 percent full by November.

Altogether, the above and underground sites have enough capacity to cover 25 percent of Germany’s natural gas consumption. They act as a kind of buffer in times of strain on the gas market or if demand spikes during unusually cold weather.

As part of Western sanctions against Moscow, Germany has already agreed to phase out Russian oil and coal. But becoming independent of Russian gas will take longer — and it won’t come cheap as the war in Ukraine sends energy prices soaring.

So far, Berlin has managed to reduce the share of its natural gas supplied by Russia from 55 percent before the invasion, to 35 percent now thanks to increased deliveries from countries like Norway and the Netherlands, and through liquefied natural gas contracts (LNG).

A network of long-distance pipelines transports gas to the Bierwang storage facility. The gas is then compressed before being injected into porous sandstone reserves deep underground.

This approach allows for enormous amounts of natural gas to be stored, but it takes longer to fill and empty than the second type of underground storage, which relies on large caverns in rock salt formations, which is more frequent in northern Germany.

“We’re on a good way to hopefully deliver the security supply this winter,” said Doug Waters, managing director of Uniper Energy Storage, which operates nine storage facilities in Germany.
