Method and Apparatus for High-Efficiency Direct Contact Condensation

Geothermal resources, the steam and water that lie below the earth’s surface, have the potential to supply vast amounts of clean energy. But continuing to produce geothermal power efficiently and economically requires innovative adjustments to the technology used to process it.

In the late 1990s, the pressure of geothermal steam at The Geysers (A geothermal plant in northern California) was falling, reducing the output of its power plants. NREL partnered with Pacific Gas and... read more

Hybrid Air-Cooled Condenser

Geothermal energy has been a viable energy source for power generation for decades. The U.S. currently has an installed base of 3,386 MW. 500 MW have been added since 2002 and an increase of another 600 MW is expected through 2016. For both new capacity and installed capacity, efficiency and power output are necessary to stay competitive.

Geothermal plants can increase efficiency and reliability through a number of systems. One of those systems is the condenser. This is where effluents... read more

Fiber-Optic Long-Line Position Sensor
Sandia National Laboratories has developed a side-emitting fiber optic position sensor and method of determining an unknown position of an object by using the sensor.  Non-electrical position sensors like the one developed by Sandia are desirable for use in hazardous environment, e.g., for measuring the liquid level in gasoline or jet fuel tanks.  This sensor is an attractive option because it does not introduce electrical energy, is insensitive to electromagnetic interference,... read more

TOUGH +: Modeling Fluid and Heat Flow in Porous and Fractured Ground
TOUGH+ is a general-purpose numerical simulation program for modeling multiphase fluid and heat flow through porous and fractured media. It is the successor to the TOUGH2 suite of codes developed at the Lawrence Berkeley National Laboratory (LBNL). Various modules can be linked to the core of TOUGH+ to describe different fluids and their compositions, or to simulate more complex, coupled processes.

Enhanced Pool-Boiling Heat Transfer Using Nanostructured Surfaces
Many devices, appliances, and systems -- such as advanced power electronics with high-power computer chips, high-power lasers and radars, and HVAC systems -- require cooling to keep them running for the long-haul and to reduce maintenance and system failures. Researchers at PNNL and Oregon State University (OSU) have developed a method using nanostructured surfaces to efficiently dissipate heat in such applications at the proper temperature.

Novel Tube-in-Tube System Simplifies Subsurface Fluid Sampling
Barry Freifeld of Berkeley Lab has developed a device that simplifies subsurface fluid sampling. The technology’s tube-within-a-tube construction is a substantial improvement to the U-tube sampling system widely used for borehole sampling today. Using only one line, instead of two, the tube-in-tube system enables the sampling device to get lowered easily through a pressure control device (such as a grease head or pack-off) for discrete level sampling of live oil and gas wells.... read more

Bore II - Advanced Wellbore Technology Characterizes Groundwater Flow and Contamination
Bore II, co-developed by Berkeley Lab researchers Frank Hale, Chin-Fu Tsang, and Christine Doughty, provides vital information for solving water quality and supply problems and for improving remediation of contaminated sites. Termed "hydrophysical logging," this technology is based on a new concept for measuring fluid flow that enables characterization of groundwater problems more quickly, more cost effectively, and with higher resolution than ever before.

Substantially Parallel Flux Uncluttered Rotor Machines (U-Machine)
A general concern based on the supply and demand trend of the permanent magnet (PM) raw materials suggests the need for elimination of these materials from electric motors (and generators) to control future costs. This invention discloses a new motor topology that eliminates the PM. Other innovations include brushless adjustable field excitation for high starting torque, field weakening, and power factor improvement and novel locks for higher peak speed. This novel machine shows promising... read more
