Strategic Partnerships

Rentech believes that having the right strategic partners will help us realize our vision of delivering clean energy solutions. The many advantages of the Rentech Process have enabled us to enter into relationships with key strategic partners and, as our business grows, we expect to enter into more of these relationships. Developing relationships with world class technology leaders allows us to provide a more complete product offering to our customers, licensees, and partners.

Denbury Resources, Inc. ("Denbury"). Together with gasification and upgrading technologies, the Rentech Process enables us to produce ultra-clean fuels and chemicals that are cleaner than petroleum-based products in terms of regulated emissions (NO_X, SO_X, and particulates) and carbon dioxide. Our process captures up to approximately 80% of the carbon dioxide generated during the production process. We have entered into an agreement with Denbury, an independent oil and gas company, to sell to them all the carbon dioxide we capture at our proposed Rentech Strategic Fuels and Chemicals Complex ("RSFCC") near Natchez, Mississippi. Denbury expects to use the CO₂ for Enhanced Oil Recovery which would effectively sequester the carbon. Under this long-term agreement, Denbury plans to build a pipeline to our Natchez facility and transport the captured carbon dioxide underground to depleted oil fields to produce otherwise unrecoverable domestic oil reserves. The CO₂ from RSFCC will effectively replace naturally occurring CO₂ that Denbury is currently extracting from its Jackson Dome deposit. It is estimated that the carbon dioxide generated in the production of one barrel of synthetic fuel like RenDiesel^® or RenJet^® will facilitate the production of two additional barrels of crude oil. Our relationship with Denbury will lower the carbon footprint of the Natchez project as well as help America's efforts to reduce its dependency on imported oil. Moreover, we believe the emissions reducing characteristics of the Rentech Process, together with our alliance with Denbury, will result in our Natchez facility being one of the cleanest fuel production facilities in the country.

UOP. UOP, a Honeywell company, whose roots date back to 1914, is the premier refining technology company in the world. UOP's cutting-edge technology advances create higher yields and higher quality products. In addition, they also create cleaner technologies and processes for a healthy environment. Rentech has entered into an agreement with UOP to jointly offer our two companies' respective technologies for the commercial production of synthetic fuels. The proprietary and patented Rentech Process can convert synthesis gas from a wide array of biomass and fossil resources into ultra-clean hydrocarbons. These hydrocarbons are then converted into finished fuels with UOP hydrocracking and hydrotreating technology. As commercialization partners, Rentech and UOP expect to increase our market reach and jointly offer proven technologies that can produce products that are cleaner than traditional petroleum-derived fuels and chemicals.

Jacobs Engineering Group, Inc. We launched an engineering program with Jacobs Engineering Group Inc., one of the world's largest and most diverse providers of engineering and construction services, to assist us in completing a commercial-scale Reactor Design Package for the Rentech Process. This work will enable us to estimate the capital costs for our reactor.

ClearFuels Technology Inc. ("ClearFuels"). Rentech has made a 25% strategic investment in ClearFuels, a biomass gasification and project development company. ClearFuels will install a demonstration-scale biomass gasifier at our Product Demonstration Unit in Commerce City, Colorado to produce syngas from bagasse, virgin wood waste and other cellulosic feedstocks. The gasifier will be integrated with Rentech's Fischer-Tropsch Process and UOP's upgrading technology to produce high-quality renewable drop-in synthetic jet and diesel fuel at demonstration scale.

ClearFuels Technology Inc. has signed an exclusive worldwide license with us for the use of our patented and proprietary Fischer-Tropsch synthetic fuels technology for the production of renewable drop-in fuels from sugarcane bagasse. ClearFuels has also signed a license with us for the use of the Rentech Fischer-Tropsch Process for the production of renewable synthetic fuels from virgin wood waste at up to twelve U.S.-based projects to be developed by ClearFuels.

ClearFuels has begun development of multiple commercial-scale biomass-to-energy projects in the southeastern United States, Hawaii and internationally. These projects will use an integrated ClearFuels-Rentech design pursuant to the licensing agreements and will be co-located at sugar mills and wood processing facilities. The U.S. wood waste projects alone are estimated to have an aggregate annual capacity of more than 100 million gallons of renewable synthetic fuels and 30 MW of renewable power.

The Wilds and Ohio State University. Rentech is collaborating with the Wilds, one of the largest and most innovative wildlife conservation centers in the world, and Ohio State University to study the effect on the entire ecosystem of growing and harvesting biomass and non-food energy crops. The collaboration will be conducted on reclaimed mine lands at the Wilds in Cumberland, Ohio. The study will also examine the utilization of marginal landscapes for the production of perennial, non-food based biofuels, and the potential for bio-sequestration of carbon and other environmental services on reclaimed land.
