Title Sort descending Date Posted Patent Information Opportunity
Ionization Based Multi-directional Flow Sensor USPN 7,523,673

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,523,673 titled "Ionization Based Multi-directional Flow Sensor."

Disclosed in this patent is NETL’s sensor system and process for multidirectional, real-time monitoring of the flow direction and velocity of a gas stream, with minimal pressure drop, such as air flow in a hybrid power generation system. The sensor comprises an ion source accompanied by a multidirectional ion collection device near the ion source. Possible applications include power generation and weather monitoring.

Laser Ignition Technology U.S. Patent Pending

This technology uses composite lasers to produce multiple temporal ignition pulses, which can be used to improve the efficiency of both laser ignition systems for natural gas fueled engines as well as laser-induced breakdown spectroscopy (LIBS) sensors. 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-fueled engines help to reduce transportation and energy costs, fuel consumption and harmful emissions compared to conventional gasoline engines. One reason for these improvements is because combustion in a natural gas fueled engine takes place in what is called a lean burn mode, in which fuel is burned with excess of air. However, this lean burn mode may lead to unnecessary misfire when the ignition spark occurs but fails to properly ignite the fuel and air mixture.

Laser Induced Breakdown Spectroscopy Probe for Simplified Light Collection and Laser Operation USPN 10,145,737

The U.S. Department of Energy’s National Energy Technology Laboratory (NETL) has developed a laser induced breakdown spectroscopy (LIBS) probe featuring simplified construction that minimizes the need for optical elements from the probes data collection path, reducing potential interference with the transmission of high quality spectra. By reducing the complexity and cost of the laser head, the invention maximizes the amount and quality of light returned for analysis and increases the usefulness of LIBS research.

Laser Spark Distribution and Ignition System USPN 7,421,166

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,421,166 titled "Laser Spark Distribution and Ignition System."

Disclosed in this patent is NETL’s laser spark distribution and ignition system, which reduces the high-power optical requirements normally needed for such a system by using optical fibers to deliver low-peak-energy pumping pulses to a laser amplifier or laser oscillator. Laser spark generators then produce a high-peak-power laser spark from a single low power pulse. The system has applications in natural gas fueled reciprocating engines, turbine combustors, explosives, and laser induced breakdown spectroscopy diagnostic sensors.

Lean Blowoff Detection Sensor USPN 7,197,880

Research is currently inactive on the patented technology "Lean blowoff detection sensor," but the technology is available for licensing from the U.S. Department of Energy’s National Energy Technology Laboratory (NETL).

Mercury Sorbent Delivery System for Flue Gas USPN 7,494,632

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,494,632 titled "Mercury Sorbent Delivery System for Flue Gas."

Disclosed in this patent is NETL’s system for the removal of elemental mercury (Hg) (and other contaminants) from flue gas streams, which involves utilizing a layer of sorbent particles contained within the filter fabric of a filter bag in a flue gas scrubbing system. Gases generated from combustion sources such as coal gasifiers, coal-fired electrical generating plants, and ore smelters are candidates, especially if the gases already need particulate removal, and if cross-contamination of fly ash by-product by sorbent/mercury is to be avoided. More than 90 percent of elemental mercury was shown to be removed when activated carbon particles were tested in this process. The particle-loaded membranes may also act as oxidizers of the elemental Hg ahead of wet scrubbers. In addition, cleanup of aqueous waste streams is possible.

Metal Oxide Promoters for Improving the Reactivity and Capacity of Oxygen Carriers for the Chemical Looping Combustion Process USPN 8,807,988

This technology, titled "Metal Oxide Promoters for Improving the Reactivity and Capacity of Oxygen Carriers for the Chemical Looping Combustion Process,” provides a mixed metal oxide carrier to improve the oxygen transfer capacity and reactivity of existing carriers. Following patent approval, the technology will be available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Metal-organic Framework Films for Gas Sensor Applications U.S. Patent Pending

This invention describes a system and method for rapid, ambient-temperature growth of metal-organic framework (MOF) films for gas sensor applications. More specifically, the invention relates to growth of MOF films on advanced sensor devices such as distributed optical fiber and passive wireless like surface acoustic wave-based sensors. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Challenge
MOF thin films have emerged as particularly attractive candidates for gas sensing applications due to their tunable porosity and pore size, enabling them to be rationally designed to selectively absorb specific gasses of interest. MOFs are especially appealing due to their high selectivity and capacity for energy-relevant gasses such as carbon dioxide and methane. A critical step towards the development of MOF thin film devices is the ability to efficiently and reliably incorporate high-quality MOF layers onto a wide range of substrates like optical fibers. However, current techniques are often inconvenient due to long reaction times, heating requirements, equipment costs and/or poor control over crystal coverage and morphology.

Method for Determining Solids Circulation Rate USPN 8,116,992

Research is currently active on the patented technology "Method for Determining Solids Circulation Rate." The technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Method for Enhancing Selectivity and Recovery in the Fractional Flotation of Flotation Column Particles USPN 7,992,718

Although research is currently inactive on the patented technology "Method for Enhancing Selectivity and Recovery in the Fractional Flotation of Flotation Column Particles," the technology is available for licensing from the U.S. Department of Energy’s National Energy Technology Laboratory (NETL).

Disclosed in this patent is a method of particle separation from a feed stream comprised of particles of varying hydrophobicity by injecting the feed stream directly into the froth zone of a vertical flotation column in the presence of a counter-current reflux stream. The current invention allows the height of the feed stream injection and the reflux ratio to be varied to optimize the concentrate or tailing stream recoveries desired based on existing operating conditions or other considerations. This novel method provides a high degree of particle collection with reduced carryover of lower hydrophobic or hydrophilic particles to the froth overflow, reduces or eliminates reliance on a clean wash-water supply, allows capture of coarse particles beyond the upper limiting size for liquid injection columns, allows capture of fine particles while mitigating the tendency of the low inertia particles to follow bubble streamlines and avoid capture, and provides other benefits over previously used methods of capture.
