Ultracapacitors have been used in heavy transportation for many years. With increasingly stringent regulations around fuel efficiency and emissions controls, their use is set to grow exponentially.
Ultracapacitors have proven to be a superior technology for regenerative braking in hybrid buses and trucks, and cold starting of diesel engines for trucks and trains.
Ultracapacitors can recover energy from a train braking and then provide additional power when a train begins to accelerate again. This facility improves energy efficiency and reduces strain on the grid by removing the spikes in power demand. Ultracapacitors can also be used to provide engine start power for locomotive trains.
Ultracapacitors are well suited to providing the necessary burst of power for starting large diesel engines. Trucks around the world are increasingly replacing lead acid batteries with ultracapacitor technology that is more reliable, guarantees starting in very cold weather and prolongs the engine starting system’s service life.
Trucks can also be fitted with a Kinetic Energy Recovery System that can decrease fuel consumption and carbon emissions by up to 32%.
Ultracapacitors can be used to recover energy from the crane during lowering and braking, and then release that energy during lifting. Ultracapacitors also enable downsizing of diesel engines as the peak power no longer needs to come from the engine.
Ultracapacitors capture braking energy in cranes to power lifting, decreasing fuel consumption by 34%.
