Market for supercapacitors to grow 30% year on year and reach $11 billion within ten years

Market for supercapacitors to grow 30% year on year and reach $11 billion within ten years Supercapacitors (ultracapacitors) are now center stage for designers of electronics and particularly power circuits. This is because they are improving faster than the batteries and electrolytic capacitors they increasingly replace.

More subtly, they reduce the need for and danger from lithium-ion batteries. For example, when placed across a rechargeable battery, they protect it from fast charging and discharging and allow more of the energy in the battery to be utilised. The result is that less battery is needed, life and safety are improved and maintenance is reduced. As a result of this and the increasing use of supercapacitors where they do not replace batteries, the growth of the leading suppliers in aggregate has increased from 25% yearly to a blistering 30% yearly rising to over $11 billion within ten years according to market research firm IDTechEx.

Of the eighty or so companies making or about to make supercapacitors and their variants such as supercabatteries ("assymetrical electrochemical double layer capacitors" such as "lithium capacitors"), only 6% are in Europe. It may therefore seem to be a strange location for the Supercapacitors Europe 2013 event. However, 25% of supercapacitor demand is in Europe, from Bombardier using large banks of them to recapture braking energy of trains to Riversimple putting them across the fuel cell in a car and extensive use by others as backup in wind turbine blade control, bus door opening, hybrid car, crane and elevator braking and many stand-by power supplies for electronics. The MAN hybrid bus in Germany is a success with the lithium-ion battery completely replaced by a supercapacitor.
