The Zero Emission Fossil Fuel Power Plant - from Vision to Reality — •Lars Strömberg — Vattenfall AB, SE-16287 Stockholm, Sweden
Sufficient supply of energy without fossil fuels is not possible the next fifty years, neither in the world, nor in Europe. Thus, we must find a solution to use coal, without endangering the environment. Carbon Capture and Storage, CCS, might be the answer.
At a cost of about 20 /ton CO2, there exist technologies, which can be ready for commercial application in 2020. After that, even more cost effective technologies will be developed. The targets set by the EU, to reduce emissions by more than half until 2050, cannot be reached without CCS.
However, CCS is very powerful, but not the only tool. All ways to reduce emissions, including renewables and nuclear must be used.
The technologies are known to a large extent. Most components exist, but are not large enough and not optimized for this purpose. The extra cost is depending on additional investments, but also largely due to the energy penalty the CO2 separation process gives.
To put emphasis behind the words, Vattenfall has started an R&D program to develop technology for CCS in a ten-year process. As part of that, Vattenfall is building a Pilot Plant including all process steps from coal input to liquid CO2. It will be ready in 2008.
In parallel, preparations for a demonstration plant are ongoing. It will be a coal fired full size plant with storage on shore. That can be ready for operation in 2015.
