A new concept of hydroelectric turbine designed for the exploitation of very low water heads (net head height ranging between 1.4 and 2.8 m) originated from an intuition by a team of professionals in the field of hydroelectric power plants highly experienced over the years and with hundreds of traditional plants executed.
There are up to now no equipments enabling the erection of acceptably profitable hydroelectric sites with a head lower than 2 m within the economical context of developed countries. Technically, existing technologies are available, but their implementation implies such civil engineering costs that they make the global investment too heavy to be supported.
A French patent application has been filed for the VLH turbogenerator unit in 2003 as the outcome of many years of experience in the design of low-head turbines. This patent has been given an international extension in 2006.
In April, 2004 MJ2 technologies was founded in order to develop the new project from the scientific, R&D and industrial point of view.
In 2004 and 2005 the preliminary studies had been completed.
In 2006, laboratory tests on small scale models had a positive outcome thus confirming the technical performances, leading by the end of the same year to the commissioning of the first plant.
Within the following 5 years MJ2 technologies closed agreements with partners in ten different European countries as well as in North and South America, performing the commissioning of more than 30 plants.
By the end of 2012, MJ2 technologies definitely became a company by Sorgent.e, which increased its initial shares up to a control share.
