Interesting predictions about the growth in the CEMS market can be found here.

It is pretty likely that as the EPA imposes restrictions and taxes on CO2 emissions that the need to maintain reliable and accurate CEMS will become even more important.

It will also be interesting to see how the Hg CEMS market progresses. As the article mentions, many plants have Hg CEMS that have been moth balled. I have already seen instances where state agencies are starting to arm twist to get data from these systems. They may not be required by the EPA but the states definitely want this data and they are pressuring utilities to provide it. I predict new regulations and even where new regulations are not enacted I suspect that states will start negotiating to add this data to reporting requirements when operating permits are renewed.

Everyone in the CEMS business has been waiting to see how this goes and now we know. A federal court has struck down the EPA’s cap and trade regulation for Mercury.

The Associated Press: EPA’s Relaxed Emissions Rule Struck Down.

This means that the EPA will have to go back and revise their mercury regulations. It will be interesting to see how they handle this. For the time being I guess it is safest to assume that the time lines for installing and certifying you mercury equipment are unchanged.
