Cleantech - 5 sociétés israéliennes parmi les 100 retenues
Energy generation - Solar
Beit Shemesh, Israel.
Product description: Large-scale solar thermal power plants
Solar thermal power plants, built by Israeli firm Solel, produce electricity in much the same way as conventional power stations, except that they obtain their energy input through concentrated solar radiation, rather than fossil fuels, and then convert it to high-temperature steam or gas to drive a turbine or motor engine. This difference means that no pollutants are emitted in producing the electricity. Solel provides the key technology for new solar power plants in the US and Spain and other sun-rich locations.

Product description: Wind power
IQWind believes it has solved one of the main problems restricting the growth of the wind turbine sector. Its flagship product, a new gear system, allows rotors to move faster than they currently do. Traditionally, the blades have had to turn at a constant speed and have been unable to take advantage of periods of the fastest wind flow. The company has applied for a patent for the system, which can be fixed to existing as well as new wind farms, and could also have sea tide energy applications.
Zichron Yaacov, Israel.
Product description: Fuel cell storage
EnStorage is developing energy storage systems through which, for instance, solar energy companies can produce uninterrupted supply even when the sun is not shining. It believes its proprietary fuel cell technology is “smaller, more efficient and lower-cost than state-of-the-art energy storage systems in the market”. The technology also works with wind-power plants and for dealing with demand management in conventional power grids. EnStorage products are based on technology developed at Tel-Aviv University.
Product Description: Biological wastewater treatment
Aqwise increases the efficiency of wastewater treatment by using what is considered to be the next generation of biological processing methods. Its Agar (attached growth airlift reactor) technology optimises oxygen transfer efficiency and maximises the surface area through which treatment takes place. Its systems have been installed around the world within the municipal sector and industry, especially in the food and drinks, pulp and paper and aquaculture areas. Its designers and consultants work on improving the efficiency of existing water plants and designing compact schemes through offices and representation in Latin and North America, Europe, the Middle East and Asia Pacific.
Product description: Electric vehicles
Better Place is working with several governments around the world to launch the necessary infrastructures that would enable electric cars to take off en masse. Israel became the first pioneer last year, potentially paving the way for widespread adoption of electric vehicles. Drivers have access to a network of charge spots and battery-switching stations, and over half of Israelis would now consider buying an electric car, according to the company’s research. Denmark, Australia, California, Hawaii and Ontario are following suit. The company is also in discussions with car makers.
