A clean-coal technology firm was awarded $12 million late last week by a federal court jury in Pittsburgh in its breach of contract suit against a manufacturer of “powdered activated carbon,” one of the key components of a newly emerging process for removing mercury from the emissions at coal energy plants.

After a seven-day trial, the jury concluded that Pittsburgh-based Calgon Carbon Corp. had breached its contract with ADA Environmental Solutions of Littleton, Colo., by failing to pay commissions on sales of carbon to Midwest Generation, an independent electric power producer.
