steam generators were designed to meet the needs of the oil and gas
industry. They accept exactly the same feed water quality as an
oilfield once through steam generator (OTSG) and they generate exactly
the same steam conditions. Particular attention has been paid to

|Graphite Energy - solar concentrator with storage|
Energy was established in 2008 to develop
and bring to market solar thermal receiver technology.
The company is privately owned and is focused on development and supply of its principle product, the G1-SSR, which is a simple and robust solar superheater and storage receiver.
|Solar Lite CSP power stations|
develops and builds decentralised solar thermal parabolic trough power
plants (Concentrated Solar Power). For the first time worldwide, the
company is applying direct steam generation commercially in a power
plant. With the SL 4600, the company has successfully developed a
parabolic trough collector made with a combination of glass fibre
composite material and an efficient thin-film glass mirror.
|Solar Reserve - heliostat with tracking mirrors|
technology, typically referred to as Concentrated Solar Power (CSP),
uses thousands of mirrors to reflect and concentrate sunlight onto a
central point to generate heat, which in turn is used to generate
electricity. More than 10 thousand tracking mirrors called heliostats
reside in a 1,500 acre field, where they reflect and concentrate
sunlight onto a large heat exchanger called a receiver that sits atop a
AREVA Solar, an AREVA
subsidiary owned in its entirety by the Group, designs, manufactures
and installs solar steam generators for the global power generation and
industrial steam needs of its customers in a dependable,
market-competitive and environmentally responsible manner. AREVA Solar
serves a broad range of power and industrial steam customers, providing
fully integrated solar thermal product offerings.
|eSolar Concentrating Solar Power
eSolar designs and develops Concentrating Solar Power (CSP) projects that start at 46MW and are scalable to any size. eSolar power plant technology utilizes small, flat mirrors which track the sun with high precision and reflect the sun's heat to a tower-mounted receiver, which boils water to create steam. This steam powers a traditional turbine and generator to produce electricity.
|Skyfuel Solar Thermal Power
SkyFuel, Inc. is a solar thermal power
technology and service provider founded in 2007. SkyFuel solar
collectors harness solar radiation to produce steam for electricity
generation and industrial applications. The Company is a leading
supplier of utility-scale concentrating solar power (CSP)
Chromasun Micro-Concentrator is a high
performance solar collector that uses the same technology as utility
scale solar systems, except now in a
much smaller package. It has been designed purposely for rooftop
integration. The MCT is low profile, lightweight
and has no external moving parts so it’s simple to mount and easy to
maintain. Using a 25X Fresnel reflector
optic the MCT generates temperatures up to 400°F (200°C).
HelioFocus-developed solar applications use the same source of solar
energy source: the dish, receiver, and heat logistics elements are used
identically for the different solutions and applications. This
configuration enables high commonality in hardware, achieving better
cost values in high volume manufacturing.
|SBP dish/Stirling systems|
The project involved the construction
of two 50 kW dish/Stirling systems close to Riyadh in Saudi Arabia.
These were the first large concentrators built using metal membrane
technology, and they still are the largest dish/Stirling systems
worldwide. The highly efficient Stirling motors were equipped for solar
operation for the first time and a very innovative, state of the art
drive and control system was developed.
The ultra-high efficiency concentrating photovoltaic (CPV) power generation system technology is based on the use of the company’s proprietary ‘Dense Array’ Convertor Technology which utilises the world’s highest efficiency triple junction (TJ) solar cells, capable of converting sunlight into electricity at around 40% efficiency.

|Solarsphere CSP Technology
Solarsphere technology was developed by the late Richard von Braun. It
used thin film structures to form a concentrating
mirror. Pictured is the 8 metre diameter unit being tested. The
a very large, very cheap concentrating mirror.
|Sunpulse Stirling Engine
The Sun pulse, a innovative water pump using solar concentrator and stirling engine. At the front of the pump is a solar collector; this reflects sunlight towards the middle where it heats up the front of a Stirling Engine. Sunvention's unique design of Stirling engine uses air at atmospheric pressure as the working fluid, and pulses at a slow 30-60 times per minute. The pump can be attached to a rotary pump, or as shown, connected to a hydraulic cylinder.
