Grünergy Technologies aims to greatly reduce these emissions in existing facilities.

The German word "grün" means green primarily, but has contexts including vegetation. Grünergy Tech, good to their name, is in the business of making green profitable by cleaning up coal burning electricity production. Grünergy is a holding company based in Frankfurt, Germany. Their subsidiaries in the U.S. and Canada are responsible for implementation of the Grünergy technology.

Grünergy's focus for the time being is capitalizing on mercury reduction in the emissions of coal burning plants. They have been able to exceed in the reduction of mercury over conventional PAC and BAC capture systems by implementing scalable systems into existing scrubbers. This is done with the attendant result of a large cost savings to the plant.

Grünergy's approach is to use their patented SEATM system in conjunction with proprietary materials which increase greatly the amount of mercury captured. This has worked consistently well. In every case, Grunergy has been able to reduce the amount of mercury in emissions, sometimes by as much as %95. This result is achieved regardless of fuel grade burned or what type of air pollution control system is currently installed.

This "Total Mercury Control" system, as Grunergy calls it, consists of a whole group of components which include the SEATM system and the proprietary chemicals mentioned. The company's stated goal is %100 compliance in all client plants with both existing and proximate environmental regulations regarding mercury emissions.

The EERC, or Energy and Environmental Research Center of the University of North Dakota is responsible for the breakthrough which Grünergy applies. Over the last twelve years, this body has fully cooperated with the U.S. Government and private industry concerns to develop a means of reducing mercury in plant emissions.

Activated carbon has long been used as an adsorbent in applications ranging from chemical warfare protective gear to industrial waste reduction. However, the EERC early on discovered through their testing that activated carbon, while somewhat effective, would never keep pace with emerging environmental standards for mercury adsorption.

A better idea had to be thought up, and soon.

Through continued research and development, the EERC invented an additive which enhances sorbents, which has been monikered the Sorbent Enhancement Additive, or SEATM. This substance, acting in concert with other specially designed sorbents accomplishes a very significant increase in mercury removal effectiveness when fitted into existing air pollution control equipment.

The EERC is not a business, however. They therefore licensed the technology for commercial use to Grünergy exclusively and world wide. Once secured, the license allowed Grunergy to begin massive field testing in power plants throughout North America. Both the EERC and the U.S. Department of Energy participated with Grünergy in these trials. The result has been cost-effective and dramatic reduction in mercury emissions, allowing plants that had an enormous hurdle to overcome avoid shut down for environmental reasons.

Grunergy Technologies offers the option for mercury emissions control personalization and preventative actions based on the industry. Pioneering research in other methods of mercury emissions control, partnering to save the environment and providing customer support for all industries are only a few of the benefits offered when working with Grunergy Technologies.
