    Supercapacitor tid bits

    Supercapacitors are a curiously neglected aspect of electronics and electrical engineering with a multi-billion dollar market rapidly emerging. Supercapacitors, sometimes called ultracapacitors, are electrostatic, not electrochemical devices. Unlike batteries, they can be fully discharged for transport and maintenance. Their behavior is more predictable and they are more tolerant of faults and damage. In the past, they have been little used because they are expensive and they hold one tenth of the electricity per unit of volume or weight.

    Little wonder that the leaders in supercapacitors are growing sales at 30% yearly nowadays. Supercapacitors are improving much faster than lithium-ion batteries and their marketing is now more imaginative, many applications not involving batteries being opened up. The future of supercapacitors may involve rivaling the size of the lithium-ion battery market within twenty years particularly as use in vehicles and grid applications take off.

    The bottom line is that almost everywhere you see next generation electronic and power technology you see supercapacitors and supercabatteries being fitted or planned because of superior performance, cost-over-life and fit-and-forget.

    The grid storage market will reach $6.1 billion by 2018 making energy storage one of the fastest growing opportunities in the smart grid industry. Supercapacitors will become integral to grid storage, as costs go down and capacities increase.

    By 2018, supercaps will generate $1.1 billion in revenues from grid-storage, especially regenerative braking on grid-attached light rail and frequency regulation. Here supercaps can result in a 30% reduction in electrical costs. The long lifetimes and near-zero maintenance for supercapacitors make them attractive for such applications.

    The default option for grid batteries today is lead-acid, accounting for more than 55% of revenues from grid batteries currently. By 2018, this share will decline to around 30% as new grid battery technologies become commercialized. The lead-acid battery will itself get an upgrade; carbon electrodes, promising a 4x performance improvement. In addition, the ultrabattery, with combination lead/carbon electrodes will compete for grid-storage markets. In 2018, lead-carbon batteries/ultrabatteries will generate around $300 million in revenues.

    note: the many benefits of supercapicitors being designed in many applications suggest the upside of this technology is very bright indeed. Maxwell's fundies continue to look better for the future.
