The sun rises in the east of solar power plants from Amal. During the fall put ten of Cleanergy solar power units in China. The test facility of 100 kilowatts can be followed by a power plant of 50 megawatts.
The company's solar power unit consists of an 8.5 meter parabolic mirror with a Stirling engine in focus. The solvarmda engine drives a generator that provides about ten kilowatts of electricity. The idea is that thousands of such units are connected to a solar power plant which, via a converter plant, connected to the mains.
Next year we hope that the Chinese are buying an entire power plant, says Alexander Vestin, business developer at Cleanergy.
It would be a real boost for the company, as the last two years made a few tens of demonstration units in small scale. If china order goes through, it means that Cleanergy to assemble 5000 stirling engines.
We are in contact with suppliers who can supply such large quantities.
For nearly 50 years, several Swedish companies have tried to do business on the Stirling engine. But so far, almost all efforts failed. Just Kockums has been successful with its submarine engine, but then, it has been expensive motors in small series. Now it's about large-scale production of cheap engines.
What speaks to us is that today's manufacturing methods gives better dimensional accuracy, which is a prerequisite for the Stirling engine, says Alexander Vestin.
Biogas-powered CHP plant is Cleanergy second application of the Stirling engine. Among others, the Russian gas company interested to have power plants along its pipelines.
