Not every energy technology that is explored is going to lead to a successful new power industry. Osmosis power was one of the more unusual technologies we’ve come across. But now, after a few years of investigation, it appears that this technology is not a viable option for larger scale power generation.
Statkraft, the Norwegian company which had opened a pioneering research facility to explore the potential of osmotic power generation, has closed its operations. Moreover, a recent research publication looking at the technology finds that biofouling, the accumulation of algae, bacteria, and other organic material on surfaces where they adversely affect the performance of the system, makes the technology unfit for power generation at the present time.
It is not inconceivable that further technological developments might be developed that could make osmotic power generation a viable system. However, with so many other ways of producing power cleanly and inexpensively, and with the other challenges presented in using osmosis, it is likely that this option will remain shelved.
