Ultracapacitors are playing an increasingly important role as efficient high power energy storage devices. UC market has shown 30% CAGR since 2009. Leading consultancy IDTechEx estimates that by 2021 the directly addressable segment of large format ultracapacitors (over 100F) is forecast to reach $4bn USD. The same research identifies low energy and power density, together with high costs, as the main factors inhibiting further market growth.
Skeleton Technologies (SKL) has developed a patented carbide derived carbon (CDC) ultracapacitor technology, which enables a four-fold increase in power density and twice the energy density and, approximately halves the cost/performance ratio. Contingent on the specific application, in most cases the economic impact of an ultracapacitor based energy solution returns its value more than ten-fold over its lifetime as monetary savings in energy consumption and reduces emissions accordingly.
The technological challenge of the project lies with scaling CDC production from TRL 6 by deploying large-scale fluidized bed reactors at a certified chemical manufacturing site to achieve TRL 8.
