Piezoelectric Axial Flow Microvalve 7,159,841

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,159,841 entitled "Piezoelectric Axial Flow Microvalve."

Disclosed in this patent are the design and functionality of NETL’s piezo-electrically operated microvalves and their use in fuel cell systems, which consist of an assembly of individual fuel cells into a stack. The microvalve improves flow control over the entire fuel cell system by integrating flow distribution and controlling of individual fuel cells within the stack. By controlling fuel flow in each individual cell, the microvalve system can prevent the overheating and under-performing of a portion of the stack, thereby avoiding reduced efficiency and energy output for the entire stack.

Method of Applying a Cerium Diffusion Coating to a Metallic Alloy 7,553,517

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,553,517 titled "Method of Applying a Cerium Diffusion Coating to a Metallic Alloy." This invention is applicable to advanced, next-generation power plant components; solid oxide fuels cells; heaters and heat exchangers; or any other application where oxidation-resistant metals are needed.

Disclosed in this patent is NETL’s robust, inexpensive process for increasing the oxidation resistance of nickel-based superalloys, as well as ferritic and austenitic stainless steels. The process involves applying a cerium oxide (CeO2) slurry to the metal surface, followed by heat treating to induce microstructural changes in the surface by cerium diffusion.

Laser Spark Distribution and Ignition System 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.

Regenerable Sorbents for CO2 Capture from Moderate and High Temperature Gas Streams 7,314,847

The Department of Energy’s National Energy Technology Laboratory is seeking licensing partners interested in implementing United States Patent Number 7,314,847 titled "Regenerable Sorbents for CO2 Capture from Moderate and High Temperature Gas Streams."

Disclosed in this patent is NETL’s process for making a granular sorbent to capture carbon dioxide from gas streams. The sorbent is made by homogeneously mixing a reactive substrate containing an alkali metal with an alkaline earth metal-containing moiety to form a mixture; adding water to the mixture; and drying the mixture. After drying, the sorbent is placed in a container permeable to a gas stream. The sorbents produced by this method absorb up to 38 times more gas than current methods.
