The Department of Energy’s National Energy Technology Laboratory is seeking licensing partners interested in implementing United States Patent Number 6,908,497, titled "Solid Sorbents for Removal of Carbon Dioxide from Gas Streams at Low Temperatures."
Disclosed in this patent is a new low-cost carbon dioxide (CO2) sorbent that can be used in large-scale gas-solid processes. Researchers have developed a new method to prepare these sorbents by treating substrates with an amine and/or an ether in a way that either one comprises at least 50 weight percent of the sorbent. The sorbent captures compounds contained in gaseous fluids through chemisorptions and/or physisorption between layers of the substrate lattice. The polar amine liquids are located within these layers. This method eliminates the need for high surface area supports and provides absorption capabilities independent of the sorbent surface area, and can be regenerated.
The U.S. Department of Energy’s National Energy Technology Laboratory (NETL) has developed a method for achieving tunable gas sensitivity of surface acoustic wave (SAW) devices. The innovation implements a class of materials with tunable absolute film conductivities called conducting metal oxides (CMOs), which enables SAW devices to be calibrated for gas sensitivity in diverse harsh-environment conditions.
Research is active on the design and synthesis of a new carbon dioxide (CO2) capture solvent based on PEG-Siloxane. Unlike conventional gas-removal solvents, the NETL’s new solvent technology is hydrophobic and has a low vapor pressure. A hydrophobic solvent with low vapor pressure is highly advantageous because it can reduce the cost and energy-consumption associated with CO2 capture by simplifying solvent regeneration and negating the need to remove water from fuel gas. For example, this solvent operates above room temperature and can be regenerated using low-grade and waste heat, whereas commercially available solvents operate below room temperature and can’t be regenerated using low-grade or waste heat This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
A patent-pending computer-control algorithm invented by the National Energy Technology Laboratory enables the manufacture of single-crystal optical fibers of potentially infinite length, with improved diameter control and faster growth, using a laser-heated pedestal growth (LHPG) system. These fibers can be used to fabricate sensors that can withstand the harsh environments of advanced energy systems. This technology is available for licensing and/or further collaborative research from NETL.
Challenge
Single-crystal optical fibers made of sapphire and other materials are only commercially available in short lengths of less than 2 meters. Using conventional technologies, length is limited by the finite size of the feedstock pedestal and equipment constraints that prevent supplying more feedstock material without compromising crystal quality. A robust technological solution is needed that allows replacement of the feedstock pedestal with minimum crystal defects and more consistent diameter for long single-crystal fibers. Other algorithms have been studied, but none has offered the ability to produce fibers of arbitrary length.
Research is active on a method to convert methane into synthesis gas using a mixture of metal oxides. The resulting syngas could be used to manufacture more valuable chemicals. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
A patented technology invented at the U.S. Department of Energy’s National Energy Technology Laboratory enhances chemical looping combustion by providing tri-metallic ferrite oxygen carriers that offer greater durability and better reactivity than traditional oxygen carriers. Tri-metallic ferrite oxygen carriers also eliminate agglomeration issues, improve reduction rates, and offer similar costs when compared to traditional oxygen carriers, with convenient preparation using readily available materials. This technology is available for licensing and/or further collaborative research from NETL.

This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Challenge
Natural gas (NG), which is composed primarily of methane, is one of the most abundant, low-cost carbon-containing feedstocks available. The economically available route to produce valuable chemicals from methane is via synthesis gas followed by different chemical routes to manufacture the desired chemicals. In a large-scale industrial plant, the production of syngas accounts for a large part of the total costs. Therefore, it is important to develop more efficient and cost-effective methods for the conversion of methane to syngas.
The innovation represents a BIAS particle sorbent suspended in a non-aqueous fluid carrier (slurry) that is capable of CO2 sorption, is easy to incorporate into established power plants, and can minimize energy and infrastructure requirements.
Challenge
Carbon sequestration can reduce the emissions of CO2 from large point sources and holds potential to provide deep reductions in greenhouse gas emissions. Amine-based solid sorbents are effective and economical agents for CO2 capture from gaseous mixtures. However, because of the high concentration of CO2 in many feed streams, a large quantity of the gas often reacts with the sorbent exothermically to produce excessive heat, which must be removed from the sorbent to prevent temperature instability within the reactor and to eliminate potential degradation of the sorbent. Reducing the damage to sorbents with this technology and method can increase efficiency and reduce replacement costs faced by industries.
This invention describes a system and method for detecting corrosion in natural gas pipelines using an optical platform or a wireless platform. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Challenge
The U.S. Energy Information Administration states that natural gas accounts for nearly 30 percent of energy consumption in the United States. More than 300,000 miles of natural gas transmission and gathering lines deliver this valuable energy source to consumers. Like any energy infrastructure, this network of pipelines requires significant maintenance costs. In the case of natural gas pipelines, corrosion accounts for around 25 percent of incidents over the last 30 years, 61 percent of which was caused by internal corrosion.
The corrosion-related annual cost for such incidents amounts to $6 to $10 billion in the United States each year. Therefore, a need exists to monitor corrosion inside of the gas pipelines to implement corrosion mitigation and control before any failure.
