DKRW Signs Fischer-Tropsch Technology Master License Agreement with Rentech, Inc.

Houston, Texas - DKRW Advanced Fuels LLC (DKRW-AF), a wholly-owned subsidiary of DKRW Energy LLC, headquartered in Houston, Texas announced today that it has signed a Master License Agreement (MLA) with Rentech, Inc. (AMEX:RTK), for the use of Rentech's patented and proprietary Fischer-Tropsch (FT) coal-to-liquids (CTL) technology for producing up to 500,000 bpd of liquids.

Concurrent with the signing of the MLA, DKRW-AF’s wholly owned-subsidiary, Medicine Bow Fuel & Power LLC (MBF&P), has signed an individual site license for its proposed Medicine Bow Project in Medicine Bow, Wyoming. The first phase of the Medicine Bow project is being designed to produce approximately 11,000 bpd of ultra-clean diesel fuel and other fuels from Carbon Basin coal.

MBF&P has already entered into an agreement with Arch Coal Inc. (Arch), the second largest U.S. coal miner owner and operator, for the purchase of high btu, low sulfur coal from the Carbon Basin Reserve. Arch will act as constructor and operator for the Medicine Bow underground mine sufficient to support the first phase of the Medicine Bow project and to expand up to 40,000 bpd.

The Medicine Bow project will transport diesel and other fuels via pipeline to major energy companies in the region. Power, carbon dioxide, and other products will also be produced and sold from the Medicine Bow project. During the initial phase, it is anticipated that power (45 MW) not utilized in the CTL project will be sold to regional electricity providers. Carbon dioxide will be stripped, sold via pipeline and sequestered in regional enhanced oil recovery operations. Sulfur will be removed from the process, solidified, and sold into the agricultural market. The Medicine Bow project’s power will be produced in gas turbines in combined cycle mode from the synthetic gas and by steam turbines using the steam generated by the gasification and the FT processes. The end result is that the Project’s electric power is produced with very low carbon dioxide and SOx emissions.

Robert Kelly, president of DKRW-AF and MBF&P, stated, "We are convinced that coal-to-liquids will play a major role in North America's energy future. We believe that Rentech has the technology to make this vision a reality."

"DKRW-AF’s business focus is to utilize the world’s abundant coal reserves along with key technologies to produce new, reliable, and more environmentally friendly energy supplies. We have multiple opportunities and expertise which will enable us to become a leader in the CTL industry within the next 5 years," stated Jon Doyle, a DKRW Energy LLC partner.

"In terms of both energy policy and national security policy, this is an important industry for the United States to develop," concluded Robert Kelly.
