Electricity from coal accounts for about 40% of the total electricity consumption in Germany. Obviously, we depend upon it. As long as this is true, however, we should endeavor to operate our coal-fired power plants with as few emissions as possible. Unfortunately, CO2 is not the only substance we have to worry about. What many people don’t know is that power plant emissions contain mercury, a highly toxic heavy metal that enters the environment through the air and has been found to accumulate mainly in predatory fish.

Electricity from coal accounts for about 40% of the total electricity consumption in Germany. Obviously, we depend upon it. As long as this is true, however, we should endeavor to operate our coal-fired power plants with as few emissions as possible. Unfortunately, CO2 is not the only substance we have to worry about. What many people don’t know is that power plant emissions contain mercury, a highly toxic heavy metal that enters the environment through the air and has been found to accumulate mainly in predatory fish.

From 2019, power plants will have to adhere to stricter limits for mercury. As a result, the IED Directive of the EU will only allow for a maximum of 10 micrograms per standard cubic meter. So, what are the technical possibilities of capturing the mercury before it gets into the air? How can we reconcile our energy needs with the need to protect our environment?

This blog is accompanying the construction of our complex cleaning system and is concerned with: Overall, how much mercury can be removed? During the ongoing operation of the power plant, will all the renovations go according to plan, just as the engineers thought they would? Furthermore, there is background information about mercury emissions to consider.
