Cleantech is still one of the central topics in today’s businesses environment. In spite of the crises, European government is continuing its strong support of cleantech development programs. As the result, today we can find a lot of technological innovations related to clean and sustainable technologies. Here is a list of seven French startups that are developing different innovative technologies with a promising market potential.
Ennesys Converts Waste Water Into Energy
Ennesys has developed a technology that allows to convert waste water of a building into a source of heating and electricity using microalgae. These algae have nothing to do with algae that we used to see in the sea. We are talking about microalgae that are placed in transparent plastic tubes that form so-called photoreactors. Waste water passing through these reactors feeds algae, which start growing instantly in the presence of light (photosynthesis process). Resulting biomass is used as biofuels for a cogeneration system that produces heat and electricity.
NaWATechnologies Brings Innovation to Energy Storage
The company brings to the market a family of ultracapacitors with performances surpassing current technologies by a factor of ten. NaWATechnologies patented technology enables to reach higher power density (capacity, equal to quantity of energy stored in the device) at lower costs. The major applications of this technology cover smart grids, electric hybrid vehicles, mobile phones and aeronautics.
Green Leverage Converts Industrial Waste Heat into Electricity
Industrial waste heat is energy that is generated during industrial processes without being put to practical use. The sources of waste heat are combustion gases discharged to the atmosphere, different heated products coming from industrial processes, and heat transfer from hot equipment. GREEN LEVERAGE’s technology allows to capture and reuse waste heat in other industrial processes for heating or generating mechanical and electrical energy. Green Leverage systems can produce up to 20% of the total industrial electricity needs from its waste heat. Moreover, it is a clean energy production, allowing industries to reduce carbon footprint of their plants. Energy intensive industries such as cement, glass manufacturing, aluminum, iron and steel production might be very interested in such technology.
Hekyom Develops ‘’Green’’ Heating and Cooling Systems Based on Thermoacoustic Technology
The company implements the results of research coming from the French National Center for Scientific Research made in thermoacoustics. Thermoacoustics is a physical phenomena involving the conversion of sound energy to heat energy and vice versa. Acoustic wave energy can be converted in heat as well as in cold. On the basis of thermoacoustics Hekyom develops eco-friendly heat pumps and refrigeration systems. The major advantages of these devices over conventional technologies are their inherent mechanical simplicity (the systems operate with almost no mechanical moving parts, reducing the cost of maintenance to trivial levels and substantially increasing their operational life) and the use of environmentally friendly working gases.
Disasolar Develops Flexible Photovoltaic Systems
DisaSolar has developed an innovative technology of inkjet printed photovoltaic layers. Flexible solar panels can be installed on the roofs of trains, cars, boat hulls and tents. Being transparent or colored, they can be part of buildings’ facades. At the same time, manufacturing method of these flexible panels is cheaper than the production of classic, heavy silicon solar panels. Moreover, printed solar panels, unlike the traditional one, does not involve the use of heavy metals and chlorinated solvents.
Innoveox Converts Toxic Liquid Waste into the Water
Technology developed by Innoveox allows the treatment of all forms of organic waste. It is especially effective in treating hazardous industrial waste such as oils, solvents, pesticides and also complex, corrosive and resistant waste. Liquid waste is heated to 400 C under a high pressure of 250 bar, after which the oxygen is injected. This triggers the oxidation and near-total destruction of the organic matter. The water produced by this process can be reused or released directly into the environment. Metals and minerals can be recovered and also reused. Today it is the world’s first eco-friendly method for recycling of such waste. The major markets of this technology are refining, chemical and petrochemical industries. Innoveox has already a portfolio of contracts with companies such as Total, Air Liquide, Akrema.
Sunhy Energy Reduces Transport Fuel Consumption
Company has developed a technology that allows to purify and reduce fuel consumption of transport and stationary power systems. SUNHY ENERGY solution is about injection of a small amount of hydrogen in the combustion chamber of an engine, turbine, or boiler, which reduces emissions and fuel consumption. For example, for a four cylinder gasoline engine, injection of 4% of hydrogen can reduce fuel consumption by 17%. This innovation has a big commercialization potential among big fleets owners.
