Major UK Carbon Capture and Sequestration Project on Thin Ice

Concerns over cost may lead to Scottish plan being pulled

Major UK Carbon Capture and Sequestration Project on Thin Ice

The Guardian reported yesterday that a major carbon capture and sequestration (CCS) project planned in Scotland may soon bite the dust. The project, slated for the Longannet coal power station, to the northeast of Edinburgh, has been heavily supported by the government, but apparently the price tag might be too high in current economic and political conditions.

The Longannet station (pictured), owned by ScottishPower, has a massive generating capacity of more than 2300 megawatts. The idea was to capture some of the CO2 emissions and bury them under the North Sea. The collapse of this project might not bode well for the United Kingdom's CCS goals, though some officials said that this was just one project and others will still follow.

According to a recent report from the UK-based Carbon Capture and Storage Association, the government has said it will back three further projects after Longannet, due to go into operation by 2018. But even before this potential problem arose, the report noted:

"The investment case for CCS remains uncertain due to the absence of a firm timetable and a clear roadmap for how these demonstrations will enable and form part of a large scale deployment of CCS in the UK."

The report also notes that most likely 20 to 30 gigawatts of CCS-fitted power plants will have to be in operation by 2030 to meet emissions targets and a growing energy demand. If the Longannet project is any indicator, such targets seem unlikely at this point. And if this sounds familiar, the United States has not fared much better on CCS to this point. There is the ongoing nonexistence of FutureGen, as well as the recent shutdown of a CCS project at a plant in West Virginia. Attitudes remain somewhat split about whether CCS will actually prove cost-effective—and just plain effective—enough to help draw down CO2 emissions, and high profile failures or postponements such as these do little to clear the picture.

This photograph shows a car with the words “We Drive Solar” on the door, connected to a charging station. A windmill can be seen in the background.

The Dutch city of Utrecht is embracing vehicle-to-grid technology, an example of which is shown here—an EV connected to a bidirectional charger. The historic Rijn en Zon windmill provides a fitting background for this scene.

We Drive Solar

Hundreds of charging stations for electric vehicles dot Utrecht’s urban landscape in the Netherlands like little electric mushrooms. Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses.

Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Those arguments are not yet settled. But big automakers like Volkswagen, Nissan, and Hyundai have moved to produce the kinds of cars that can use such bidirectional chargers—alongside similar vehicle-to-home technology, whereby your car can power your house, say, during a blackout, as promoted by Ford with its new F-150 Lightning. Given the rapid uptake of electric vehicles, many people are thinking hard about how to make the best use of all that rolling battery power.
