Not Under My Backyard One German Town's Fight against CO2 Capture Technology
The next Chernobyl? A death blow to tourism? Poisoned drinking water? The residents of Beeskow, Germany worry that a planned CO2 storage facility under their town could end in disaster and are fighting the project. Europe, though, hopes the technology will drastically reduce emissions.
The signs are everywhere -- on church towers, on fences surrounding private homes and in storefronts. At first glance, the scenes evoke the large-scale protests against nuclear power that rattled Germany in the 1970s and 1980s. The resemblance is no accident. Residents in the quiet town of Beeskow in the eastern German state of Brandenburg are gearing up for a fight. They fear the pollutants that are about to be pumped beneath their homes could become the next Chernobyl.
"A field trial under our community is not acceptable," says Beeskow Mayor Frank Steffen.
The town's residents are upset about plans by a German division of Swedish energy giant Vattenfall to build a carbon dioxide (CO2) storage facility in a saline aquifer far beneath Beeskow's cobblestone roads. The site is one of a handful across Europe where companies and governments want to test a process known as carbon capture and storage (CCS), a technology that proponents say will massively reduce CO2 emissions from coal-fired power plants. Instead of belching the emissions into the sky, CCS technology would capture, liquefy and then pump the CO2 into underground storage sites.
CCS has been hailed by advocates as a way to greatly reduce the amount of CO2 emitted by pollution-heavy industry and help countries achieve their goals for limiting emissions of greenhouse gases in order to slow or stop global warming. The International Energy Agency (IEA) estimates that wide-spread adoption of CCS would be the cheapest way to cut emissions by half by 2050, arguing that the technology could contribute nearly 20 percent of those cuts. Critics, however, note that CCS technologies also require significant amounts of energy. The Intergovernmental Panel on Climate Change (IPCC) estimates that power plants would need between 11 percent and 40 percent more fuel once CCS technology is installed.
Negative Impact on Tourism
The most vehement critics of CCS, though, have proven to be those living near the planned facilities. "They are experimenting with humans," says local vacation home owner Mike Kess, the 38-year-old spokesman for a group of residents that formed to combat Vattenfall's plans. If CO2 leaks from the aquifer, they fear, it could contaminate drinking water -- or worse. Residents are also concerned the facility could negatively impact tourism in the economically volatile region. "Who wants to go on vacation in an area with this kind of stigma," asks Kress?
Chancellor Angela Merkel's cabinet is expected to approve legislation in September that would open the door to greater CCS research at different sites around the country. The bill is the implementation of a 2009 European Union directive establishing the legal framework for the "safe geological storage" of CO2 to contribute to the fight against climate chage.
Under the German bill, tests could be conducted in the country with a maximum total volume of 8 million tons per year, and mass quantities could only be stored after the technology's "harmlessness has been demonstrated." The government views CCS as a necessary step to secure the country's long-term energy supply. Under the bill, each German state would be given greater freedom to issue permits for research at potential CO2 storage sites -- in saline aquifiers like the one planned in Beeskow, or in empty oil and gas fields in other parts of the country.
Coal's Role in Germany's Energy Mix
"There is no way we can turn off all the coal-fired plants from one day to the next," says Steven Bretz, a member of Merkel's Christian Democratic Union (CDU) in Brandenburg. His party is in the opposition in Brandenburg, the state that surrounds the German capital, but the CDU supports the government in its decision to allow the exploratory work in Beeskow and elsewhere.
Although CDU leaders in the area have promoted renewable energies, they also argue -- in contrast to the opposition Green Party -- that coal-fired plants must remain an essential part of the energy mix for the foreseeable future. And even if the number of coal plants doesn't increase dramatically in industrialized countries like Germany, reliance on coal for power is growing massively in emerging economies like China and India. "We have a moral obligation to participate in CO2-reduction on a global level," Bretz says. He feels the country has a duty to develop technologies for cleaner production of coal-based energy that can create a model for other countries and be exported.
In Beeskow, where permission to commence has already been granted by the state, locals are hoping that the national debate over CCS technology will give them the momentum they need to stop Vattenfall's plans. Local officials have filed a petition with the state government in the hope of having the permit revoked. Instead, they are proposing that the site be used for a project to explore geothermics, the generation of heat and energy using naturally occurring heat from far below the earth's surface.
'CCS Can Build a Bridge'
Officials at Vattenfall acknowledge the need for discussions. "We think this technology can build a bridge between coal and renewable energies to give the latter the time they need to grow in terms of reliability and efficiency," says Vattenfall spokeswoman Katharina Bloemer. At the moment, a number of CCS technologies are being tested in pilot projects in Germany, France, Norway, the Netherlands, Australia, Canada and the United States. In Europe, many of the pilot projects are being partly funded by the European Union, which has earmarked more than a billion euros for the test sites.
Researchers from the German Research Center for Geosciences (GFZ) in the town of Ketzin in northwestern Brandenburg, have so far reported success with a similar test facility operating there. They have already injected some 36,000 tons of CO2 at a depth of 650 meters (2,132 feet). Project coordinator Hilke Würdemann recently told SPIEGEL the results have been promising. "The conditions are as we expected."
