Skeleton Technologies ultracapacitors for crane applications

RTG PORT CRANE
ENERGY RECOVERY

KERS (Kinetic Energy Recovery System) captures and re distributes energy during lowering of freight and supplies energy during lifting of freight

Benefits of our solution

  • Longer lifetime of KERS compared to a li-ion solution
  • Retrofit & downsizing of the diesel powerplant leads to 60% savings
  • Over 30% less greenhouse gases emissions
  • Less noise from the diesel engine during operation
  • Preventive attitude towards regulation changes

Challenge

Reduced emissions & minimized fuel consumption

  • Key Challenges
  • Ca.25% of global CO2 emissions come from transport
  • 30%-40% of this total is produced by cargo transport - Read more
  • Emissions will need to fall by 95% by 2050 to ensure that the marine transport sector adheres to the Paris Climate Agreement - Read more
  • Most ports still use only diesel-powered RTG cranes.
  • The diesel engine needs to be sized to cater for power peaks
  • The greenhouse gas emissions have to be lowered
  • It is required to lower the noise level
  • known consequences
  • Higher CAPEX due to larger engine sizing
  • OPEX more costly than it needs to be due to inefficient use of engine
  • Regulation becomes more stringent
  • Cranes enforced to be upgraded

solution

KERS – most economical solution

  • what we offer
  • KERS* captures and re-distributes energy during lowering of
    freight and supplies energy during lifting of freight
  • ADVANTAGES OF OUR PRODUCT
  • Smaller and 8 times cheaper vs a fully electrified solution of similar requirements
  • Operating temperature range -40°C to +65°C
  • Simpler monitoring and system health checks

case study

Port of Muuga (part of HHLA)

  • Situation WITHOUT ULTRACAPACITORS
    Prior to adding the ultracapacitors Kalmar E-one RTG consumed on test cycle 30.21 l of fuel.
  • Situation WITH ULTRACAPACITORS
    After the addition of KERS of  ultracapacitors the average fuel consumption for doing the same operation cycle was 2.86 liters less (27,35 l).
