USA Solar Companies surviving the Downturn The Solar Industry has seen a massive shakedown with hundreds of bankruptcies and thousands of jobs lost. There has been no solar energy company which has been left unaffected by this brutal consolidation. Even the biggest solar panel manufacturers have seen huge losses and restructuring. The biggest solar companies […]
However Solar Thermal Technology is finding a niche in Hybrid Fossil Fuel Power Plants . The reason that Solar Thermal is gaining traction in Solar Hybrid Plants is
1) They can use the existing Electricity and Transmission Infrastructure of the new Fossil Fuel Plant or the Existing One
2) Solar Thermal Technology in most cases generate Steam which can be used by the Turbines of the Fossil Fuel Plant saving additional costs
Solar Thermal Energy has been losing out in the last couple of years to solar photovoltaic energy which is seeing a huge increase in demand amidst very low prices.Some of the major solar thermal energy projects in the globe have been converted into solar pv installations due to its lower costs.Some of the major solar thermal energy companies like Solar Millennium have sold their solar thermal portfolios to other companies while Stirling Power Systems has gone bankrupt.Tessera has sold its solar thermal plants which had gotten DOE Loan Guarantees in California to Solar Developers who have made these solar thermal plants into solar panel ones.However there are some companies like eSolar and Brightsource Energy which are powering ahead with their technologies and projects with backing from big industrial MNC conglomerates like GE and Areva.Their Power Tower Technologies are supposedly more efficient than the mainstream parabolic toughs that are used.
eSolar is a US based Solar Thermal Technology Startup which has managed to raise $182 million from top VCs and investors and managed to win contracts to build solar power plants using its properietary Power Tower Technology in the US,China and India.Note like Brightsource Energy,eSolar is one of the most promising CSP startups which has managed to get funding and contracts,it now needs to execute to deliver on its potential.
Solar is using the Power Tower Technology same as Brightsource Technology which differs from the parabolic trough mainstream CSP Technology.Note Parabolic Trough Technology is used by most of the established Spanish players like Abengoa.It is also the Technology used in the 392 MW largest solar thermal plant in the US built in the 1980s by Luz.In this technology thousands of heliostats (mirrors) reflect the solar light onto a “Power Tower” where water or salt is heated up.This heat energy is then transferred into Electrical Energy through standard Steam Turbines and Generators used in Gas,Nuclear and Thermal Power Plants.
Note China’s Solar Market is a highly competitive and protected one with outside solar companies hardly having any presence similar to Japan’s market.First Solar which signed a massive gigawatt contract to build a plant in Ordos has seen only delays as Chinese solar manufacturers opposed the plant.First Solar is still trying to build the plant signing a new JV with one of China’s 5 big utilities.eSolar another CSP company got a contract to build a plant with China but till date construction does not seem to have begun there also.The Chinese government seems mostly interested in high-tech technology (First Solar,eSolar) rather than run of the mill players.Even these technology companies have failed to make much headway.Remains to be seen whether SkyFuel Succeeds.
Solar Thermal Technology has been facing tough competition from its sister Solar PV Technology in recent times.Despite strong government subsidies and support,numerous drawbacks have contributed to this Technology losing out to Solar PV in a number of projects in the US notably by Tessera.However a number of startups and big conglomerates continue to make huge investments in this technology.Spain and US are leaders in implementation of this Solar Technology type,however others like India and China are to building CSP plants as their energy needs continue to grow.Note like Solar PV,there are a number of different technology types for CSP like Power Tower,Parabolic Troughs,linear fresnel technology and Stirling Engines.Here is a list of the most important Solar Thermal Companies (Technology Providers cum Project Developers)
