Next Generation of Power Generation
Nanogen Power Systems is a solar power technology developer and manufacturer offering 250kW to 10MW solar energy generating systems (SEGS).
Through the combination of exclusive patented technology, OEM licenses, and proprietary technology and designs, Nanogens has successfully downsized concentrated solar power (CSP) technologies to bring the economics of large solar energy systems to the industrial, commercial and utility sectors in a smaller, robust and more cost effective package.
The company has developed both fixed and portable SEGS.
Fixed | Portable SEGS
Nanogens Fixed SEGS include 1MW to 10MW power plants designed for grid-connected use. These may be used for co-generation compliance along with fossil fuels, and provide renewable energy credits for AEPS and RPS requirements.
Nanogens portable SEGS are available in 250kW increments up to 1MW. These units are fully portable and capable of being transported in cargo containers worldwide and then deployed to provide supplemental power to rural and island systems, off-grid power in emergency disaster relief efforts and for supplemental power to industrial, commercial and government customers.

Nanogen's NanoCSP technology represents the integration of exclusive patented technology, OEM licenses, and proprietary technology and designs, resulting in a successfully down-sized Concentrating Solar Power (CSP) technology. Just as productization of Photo-Voltaic (PV) technology has resulted in affordable PV cells used in calculators, watches and cell phones, Nanogen has scaled down the CSP technology previously used exclusively in power plants costing hundreds of millions to build and operate.
CSP technology was initially developed exclusively for the power industry and is the driving technology in almost all large-sized solar plants. Nanogen has completed development of its NanoCSP technology, a micro-sized and packaged CSP system which is modular, portable and affordable.
In 2009, the U.S. installed about 435 megawatts of solar. That doubled to about 1,000 megawatts in 2010 and many forecasts point to 2,000 megawatts installed in 2011. Modularity of PV solar panels has allowed solar to grow rapidly. Nanogens NanoCSP technology will help drive continued growth in solar power generation.

Nanogen SEGS utilize proven generator/engine combinations (gen-sets). The company is a licensed original equipment manufacturer (OEM) for the leading steam turbine and ORC engine technologies used in Nanogens SEGS.
Nanogens smaller systems (<1MW) are powered by Organic Rankine Cycle (ORC) engines which use a closed-loop system. The larger plants are powered by traditional steam turbines, which use the solar heat to boil water through a heat exchanger, which operates like a radiator in an automobile. The steam is later condensed into water and recycled.
The ORC engine is similar to a steam cycle like the kind used in producing electricity by heating water. Water boils at 212 degrees and the resulting steam comes out of the boiler at high pressure which then drives a turbine. When the steam exits the turbine it is cooled and condenses back into water. A pump then sends the water back to the boiler to make a continuous cycle. An ORC engine uses an organic compound instead of water and the organic working fluid boils furiously at low temperatures, about 140 degrees. The cycle is the same as a steam cycle but it requires much less heat so low temperature solar water panels can be used along with low temperature geothermal wells or waste heat from industrial processes.
The ORC can continue to operate at lower temperatures (unlike a steam turbine, which shuts off if the steam temperature drops). The Nanogen SEGS used in the portable plants can operate at lower temperatures, eliminating the need for highly skilled steam contractors. Customers setting up the portable plants in the field can use standard plumbing skills. The ORC can operate at 10 percent of its operating efficiency and the engine would still continue to operate. In other words, it can operate in cloudier places than the large-scale desert systems. In addition, the ORC engines have significantly lower operating and maintenance costs.

Nanogen has negotiated the exclusive use of the patented solar trough system for solar power applications. This parabolic trough is unique for two reasons: design & cost.
Design: The unique design allows the trough to track the sun without the mechanical tilting equipment required by all other parabolic troughs, making it stronger, more durable, and less expensive to maintain and operate.
Cost: Most parabolic trough collectors use precision optical molding equipment, fragile bent glass mirrors, and vacuum isolated glass encased absorber tubes. The patented troughs are thermal molded plastic, lined with reflective film and extremely rugged. The troughs are both very durable and affordable. By using these rugged, non-breakable troughs, Nanogen has reduced the cost of the solar collecting field by more than 70%.
The patented solar trough collector uses thermal forming to create a parabolic solar trough with a unique design. Unlike linear parabolic trough arrays, which must mechanically track the sun for maximum performance, the patented trough is molded with a patented twist which allows sunlight to stay constantly focused on the absorber tube.
These troughs are shatterproof and can easily be man-handled into position. In the existing multi-MW installations in Nevada and Spain, the solar collector field accounts for more than 60% of the cost of the project; the Nanogen troughs account for only 10% of the cost.

Nanogens proprietary thermal energy storage (TES) technology stores thermal energy to use during non-solar periods and to dispatch when it's needed most. As a result, TES allows the parabolic trough power plants to achieve higher annual capacity factorsfrom 25% without thermal storage up to 70% or more with it.
The TES tank functions as a highly insulated thermos which maintains the solar heated transfer liquid at a temperature sufficient to power the generator for between 8 and 16 hours after the sun has set.
Nanogen's P3 Portable Power Plants are available in 250kW increments up to 1MW. The P3s are fully portable and capable of being transported in cargo containers worldwide and then deployed to provide supplemental power to rural and island systems, off-grid power in emergency disaster relief efforts and for supplemental power to industrial, commercial and government customers.
These portable power plants are ideal for crisis and catastrophe relief worldwide. Additionally, our P3 provides back-up power to both the public and private sectors during service interruptions. There are also several military applications for the portable units. The P3 also serves demand for freestanding, off-grid power plants in emerging countries, remote communities and island nations.
The P3 units are housed in standard steel cargo containers and can be shipped nationwide or worldwide by inter-modal freight operations, including ship, barge, rail, truck, or cargo helicopter. While the gen-set is shipped in a standard 20-foot container, the solar trough collectors are shipped in 40-foot containers, each providing up to 480kW of generation capability. The Nanogen power plants are modular and scalable by adding additional collector containers and gen-set containers.
A typical 1MW power plant would contain 1 steam turbine gen-set in a 20-foot container and two 40-foot containers of parabolic trough collector arrays designed with fold-down walls. When the power plants are delivered on wheels domestically, there are no zoning issues and no building permits required.
The 40 foot cargo containers have six SPT troughs mounted on the inside of each of two fold-down sidewalls. Once the container is delivered to the site, either temporary or permanent, two workers using a contractors laser level and a compass, align the container with the sun at that latitude, drop down the container walls containing the solar trough panels and complete the plumbing fittings. The turbine gen-set is a plug and play module, which has been pre-wired to the transfer switch panel and needs only to have the plumbing connected. Two workers can install a Nanogen P3 unit in less than two days without any heavy construction equipment. It is the ideal off-grid power plant.
Nanogens self-contained SEGS include the ORC engine, generator, solar troughs, TES tank, heat transfer fluid, and control panel all installed in cargo containers and ready to ship worldwide.
Fixed Solar Power Plants
Nanogen's larger, fixed SEGS are available in sizes of 1MW to 10MW and larger. These systems may be utilized by large enterprises to offset significant power usage, or by independent power producers and local utilities to meet renewable portfolio standards (RPS) or alternative energy portfolio standards (AEPS).
Nanogen fixed plants are designed to be delivered as a complete system using concentrated solar heat generation with state of the art steam power generators.
Custom plants can be integrated with existing heat generators to utilize existing power generation equipment or to provide a standalone supplemental power system.
Nanogen manufactures, installs and operates the fixed SEGS.
