What is Industrial Solar Thermal?
The Technology
3 4Parabolic trough collectors tracking the sun
Solar thermal technology uses the sun’s energy, rather than fossil fuels, to generate
low-cost, environmentally friendly thermal energy; i.e. heat. Our solar systems
often incorporate thermal storage so that heat can be delivered around the clock.
Energy use does not have to stop when the sun goes down. As a result, we can
reduce fuel bills by up to 70%.
Solar thermal systems differ from solar photovoltaic (PV) systems that generate Solar thermal systems differ from solar photovoltaic (PV) systems that generate
electricity. The peak efficiency of generating solar heat is greater than 65%
compared to 20% for PV systems, and PV electricity generation stops when the sun
goes down. In addition, solar heat output increases with rising temperatures,
whereas PV suffers a significant decrease. Overall, for a given area, our collectors
deliver three or four times more energy than PV systems.
Abengoa employs parabolic trough collectors that concentrate the sun’s energy to
deliver heat in the form of hot water, steam or process heat to client facilities in
the industrial and commercial sector. Abengoa’s collectors automatically track the
sun throughout the day to maximize the capture of solar energy. Sunlight is
reflected off the collectors and concentrated onto the receiver, where thermal
energy is absorbed by a heat transfer fluid. The fluid is heated to the desired
temperature and delivered to the process loads using a heat exchanger.
Compared to fixed-tilt collectors (flat plates), tracking is advantageous because the Compared to fixed-tilt collectors (flat plates), tracking is advantageous because the
collectors operate longer during the day and energy delivery is more efficient and
uniform throughout the day. Parabolic trough systems are easily scalable whether
the need is for 1 or 50 million Btu/h output. They are also extremely flexible and
economically deliver heat from 120 F to over 400 F. Thermal energy storage tanks
can be incorporated to deliver heat 24/7 or to meet client schedules.

Investing in Solar Thermal
Why Do It Now?
The state and federal incentives have never been better for solar thermal
technology. Currently, the State of California, through the California Solar
Initiative (CSI), will provide up to $800,000 to build a commercial system that
displaces conventional energy. Additionally, our systems qualify for the Federal
Investment Tax Credit (ITC), which provides a tax credit equal to 30% of the
gross installation cost of the system.
Depending on the application, Abengoa can install a system that will provide Depending on the application, Abengoa can install a system that will provide a
simple cash on cash payback in less than 2 years. After year 2, the fuel savings
combined with incentives will grow the return on investment throughout the
life of the project.
Furthermore, solar thermal technologies reduce the emission of greenhouse
gases and air pollutants and mitigate the impact on climate change.
The incentive programs are set to expire within the next 3 years. The CSI is only
valid for systems that are operational by the end of 2017, and the money is
awarded on a “first come, first served” basis on a declining scale until the money
runs out. Additionally, systems must be operational before the end of 2016 to
capture the 30% ITC, before it decreases to 10%. As a capital investment, the
system can be depreciated over a five-year accelerated basis.

Our solar thermal technology is a zero-waste and zero-emissions system. It reduces
the emission of greenhouse gases and air pollutants, and mitigates the impact of
commercial operations on climate change. After the life of the system, the
aluminum collectors and steel piping system are profitably recycled since no
hazardous materials are used in the system.
Installing an Abengoa solar heat system is one of the most economic ways to lower Installing an Abengoa solar heat system is one of the most economic ways to lower
the carbon footprint and protect the environment. On-site energy generation
reduces the need to extract and transport fossil fuels. For many businesses, water
heating and/or steam generation can account for over 50% of greenhouse gas
emissions. For businesses required to meet sustainability benchmarks, solar thermal
systems are an ideal solution.
Primary energy consumption in the US is used 40% to generate electricity,
28% for transportation fuels and 31% as heat. While the renewable energy
focus is on solar electricity generation, solar heat is a large untapped market
with a vital part to play in the US energy mix to stabilize prices and to
mitigate the impacts of energy consumption on climate change.
