Early adopters reap the benefits

Aerospace, motorsports and defense industries are all early adopters of many technologies, which then trickle down to more general applications for a multitude of industries. Kinetic Energy Recovery Systems are a great example of a technology that was first developed for Formula 1 cars, but is gaining popularity in the automotive and transportation sectors and can prove to be a significant help in reducing carbon emissions.


Ultracapacitors are now being applied to satellite technology and space travel. The aerospace industry is particularly demanding and requires extremely low-weight, high-performance technologies that can tolerate large temperature variations and exposure to radiation. Power-to-weight ratio is particularly important as the cost of sending 1 pound to space is around €9000 and reducing overall weight, and therefore cost, is a key target for the industry. Ultracapacitors offer a very high power-to-weight ratio, are robust under challenging conditions and offer long lifespan, making them ideally suited to the aerospace industry.

The motorsports industry has a key role to play in driving fuel efficiency and leading technological thinking for the automotive industry as a whole. The sector has become a test-bed for many of the common technologies we see in the automotive industry today, from disc brakes and rearview mirrors to engine air intake and the use of new materials like carbon fiber. Motorsports is an ideal environment to apply the new high-performance systems that ultracapacitors enable and to lead engineering advancements in vehicle performance and efficiency.

Kinetic Energy Recovery Systems (KERS) are an advanced technology used in modern racecars and high performance vehicles for recovering kinetic energy under braking. The recovered energy is then used to provide additional power and boost acceleration when needed while reducing fuel consumption. With recent advances in technology, ultracapacitors now provide one of the best technology solutions on the market for KERS applications.

Why Skeleton's ultracapacitors are ideal for aerospace and motorsports

Space is a hostile place.

Our ultracapacitors are resilient to the extreme temperatures and radiation concentrations experienced in space.

Maintenance is expensive.

Our ultracapacitors can undergo millions of cycles without any significant reduction in performance, and therefore rarely need to be replaced.

Every kilogram counts.

High power to weight ratio means ultracapacitors can efficiently handle much of the ‘heavy lifting’ on board satellites, reducing the amount of weight and room needed for energy storage.

Minimal weight and maximum power output.

Our ultracapacitors deliver 60 times more power for weight compared to lithium ion batteries, and have a higher power and energy density compared to any competing ultracapacitors on the market.

Fuel efficiency is crucial.

Our ultracapacitors have efficiencies of 98%, which is considerably higher than many other energy storage technologies.

High tolerance of extremely high temperatures.

Race cars can experience extremely high temperatures near the engine. Our ultracapacitors are tolerant of high temperatures with minimal impact to efficiency and lifespan.
