Cold Turkey: How Germany Could End Russian Gas Dependency
The crisis in Ukraine has made painfully obvious just how dependent Germany and other European countries are on Russian natural gas. There are serious alternatives for supplying the vital natural resource, but they all come at a price.
At the edge of the moorlands east of Bremen, an oil derrick juts into the sky. The site, known as Völkersen-Nord 24a, belongs to the oil and natural gas production company RWE Dea and taps into natural gas reserves located 5,000 meters (16,500 feet) below the earth's surface. At the tip of the steel derrick, a German flag flutters in the breeze. But the black, red and gold banner seems out of place.
Alexey Miller, head of the Russian energy giant Gazprom, likewise finds Germany to be an attractive market. This summer, Gazprom's purchase of Wingas -- the Kassel-based trading company that controls a fifth of the German natural gas market -- is scheduled to be finalized. The acquisition will grant Gazprom authority over a 2,000 kilometer (1,243 mile) long pipeline network in addition to several natural gas storage facilities, including Western Europe's biggest, located in Rehden. It is large enough to supply some 2 million households for an entire year.
The timing of the purchases is awkward. Just as all of Europe is looking nervously at the escalating crisis in Ukraine, a significant portion of Germany's energy infrastructure is being sold to Russian buyers -- even as Moscow already plays a key role in meeting the country's energy needs.
Almost 39 percent of Germany's natural gas comes via pipeline from Russia. Thus far, at least. But what happens if Moscow turns off the tap? It is a concern plaguing many politicians in Berlin, and the rhetoric has become sharper in recent days.
Andreas Mattfeldt, a parliamentarian from Chancellor Angela Merkel's Christian Democrats who was born in Völkersen, says that RWE Dea's sale to a Russian oligarch makes him "more than uneasy." He says the deal has "extremely troubled" Germans in his Lower Saxony constituency, adding that, given Germany's existing dependency on Russian natural gas, he himself finds the transaction "very alarming." The country's energy security, he says, is "enormously imperiled."
The scenario of natural gas flows being intentionally reduced by Moscow had long been considered unlikely. Even in the chilliest days of the Cold War, the Soviet Union proved itself to be a reliable supplier. In the years immediately prior to the fall of the Berlin Wall, West Germany got fully half of its natural gas from Russia, via pipelines optimistically named "Brotherhood" and "Union."
A quarter century later, the world has become more complicated and foreign policy less predictable. The conflict in eastern Ukraine looks as though it could explode at any moment, injecting yet more uncertainty into the situation. And Russia has warned of potential delivery interruptions, a reaction to European threats of additional economic sanctions.
The issue has become a major focus of international diplomacy, with negotiators from Moscow, Kiev and Brussels meeting last Friday to discuss Russian gas deliveries to Ukraine. This week, G-7 energy ministers are meeting in Rome to discuss ways to wean themselves off of dependency on Russian natural gas.
Among the proposals on the agenda is a Polish idea to further integrate the gas supply grids of European Union member states so as to prevent shortages. Warsaw envisions the creation of a single European body that could coordinate or direct gas deliveries to and from large storage facilities on the Continent as well as make purchases. The proposal also calls for billions of euros to be made available for natural gas exploration on the Continent.
Germany too has once again begun discussing energy policy. In 2011, Merkel turned the country away from nuclear power and accelerated the development of renewable energy sources in a policy move known as the Energiewende. Now, though, geopolitical factors have suddenly become paramount in the debate over the country's future energy supply. Should Berlin increase its focus on exploiting domestic energy sources? How can Germany expand its supply network? And last but not least: What does all this mean for the environment?
Pursuing Liquefied Natural Gas
One potential solution to Europe's energy policy conundrum can be viewed at the very edge of the Port of Rotterdam, right where ships sail out into the open sea. There, a consortium has constructed GATE, a terminal on several acres of reclaimed land equipped to handle ships carrying liquefied natural gas (LNG). The tankers sail in from Norway, Qatar and Nigeria and are unloaded here. Some of the vessels carry enough natural gas to supply 60,000 households for a year.
LNG is cooled to a temperature of minus-162 degrees Celsius (minus-260 degrees Fahrenheit), which shrinks its volume to 1/600th of its original. The gas is pumped out of the ships at the Rotterdam terminal and into vast, 55-meter (180-foot) tall tanks, with walls of concrete and steel that are two meters thick. Excess heat from a neighboring coal-fired power plant is then used to re-vaporize the gas before it is fed into the pipeline network.
The facility in Rotterdam cost some 900 million to build and it can handle up to 200 tankers per year. So far this year, however, only seven have arrived. Indeed, since Queen Beatrix of the Netherlands cut the red ribbon opening the facility in 2011, a total of only 40 LNG ships have docked at the port.
The Rotterdam LNG port's slow start is primarily a function of the lack of sufficient liquefaction facilities in natural gas production countries. With several such facilities currently in the works, it seems likely that the situation will improve by the end of the decade.
There is, however, no shortage of LNG reception terminals. In Europe, there are already 22 LNG ports with more under construction. Indeed, the EU theoretically has the infrastructure capacity to cover two-thirds of its natural gas needs with LNG.
But there is another factor which has kept liquefied natural gas from playing a greater role in satisfying European energy needs: Price. For large exporters such as Qatar, it is much more lucrative to sell LNG in the Far East than to ship it to Europe. Suppliers are able to charge more than $15 per million British Thermal Units (BTUs) in Asia whereas the price in Europe is around $10. Since the nuclear meltdown in Fukushima in 2011, the price difference has become even larger as a result of Japan's increased need for natural gas.
As such, while it is certainly conceivable that LNG could become a greater part of the mix in Europe, it would mean higher energy prices. And the construction of further LNG terminals, such as the one that had been planned for Wilhelmshaven, Germany, seems unnecessary for the moment.
Exploiting Shale Gas
In the northwestern corner of Lower Saxony, on National Highway 75, the Bötersen Z 11 drilling site, belonging to American energy giant ExxonMobil, can be found. "Z" stands for "Zechstein," a term describing a sedimentary layer found in the European Permian Basin, which underlies a significant portion of northern Europe. The site was constructed almost three years ago.
At the time, everything was prepared, with technicians planning to inject a liquid deep into the ground at 450 bar (5,525 psi). The procedure would have lasted about an hour. But it didn't happen. Public protests against the procedure had become too intense to allow the project to go ahead. Today, a human-sized plug valve seals the drill site.
Aside from nuclear energy, no other technology is currently as controversial in Germany as fracking. Critics fear incalculable environmental damage, particularly to aquifers. Producers counter by claiming that the procedure is well-tested. And indeed, fracking has been employed in Germany since 1961, but only in conventional repositories in porous sandstone, which is comparatively easy to unlock.
The conflict over fracking is more rancorous when it comes to shale. Deposits in such sedimentary rock are much more difficult to access and the procedure is considered to be riskier. Though experts believe that the potential for the technology is great in Germany, shale fracking has not yet been carried out here.
But Yergin's optimism is not widely shared. Germany's Federal Institute for Geosciences and Natural Resources recently concluded in a study that "it cannot be expected that shale gas in Germany will become the 'game changer' it has in the US." German shale gas, the study noted, "doesn't play a central role" relative to deposits elsewhere in the world.
