Energy storage
Industrial applications: peak load shaving
Downsize dimension and cost of your applications by 20 – 40% with the Liduro Energy Storage system
Port cranes: calculating overall costs and savings
Genset and network factors: Based on a set of relevant factors, we calculate an estimate of savings you can make through the integration of an energy storage system and, additionally, a retrofit of your genset.
Machine power cycle (ds/ms/ms/ns)
Output power genset (kw)
Machine operating time (h)
Power source (genset or network)
Rubber-tired gantry crane
Sample calculation saving 34% of fuel:
Originally used genset: 345 kW
Storage power: 200 kW
Reduced genset: 160 kW
Total lifetime: 53,700 hrs / 10 years (average)
Fuel / CO2 savings: up to 34,6% / 63t CO2 per year
Amortization of investment: 2,5 years
Industrial applications with high peak loads
The Liduro Energy Storage is an efficient component for machines and machine networks in the manufacturing and process industry:
- Presses
- Centrifuges
- Milling machines
- Others
Presses
Sample calculation saving 225.000 kWh per Year
Originally required power: ~ 900 kW
Storage power: 450 kW (LES 300)
Peak power: LES 300: + 350 kW / - 460 kW
RMS power:~ 250 kW
Total lifetime: 53,700 hrs / 10 years (average)
The exchange of a mechanical storage through an electric storage results in an elimination of downtimes through services as well as noise
Passenger and freight elevators
The Liduro Energy Storage provides for power supply during switching or peak shaving.
Sample measurement saving 50% of energy:
Originally used genset: 45 kW
Storage power: 200 kW
Reduced genset: 22 kW
Energy savings: 50%
Reduction of energy consumption

Ultracapacitors
Liduro Energy Storage – LES 300: The scalable Liduro Energy Storage systems for stationary and mobile applications are characterised by a high power density. With their compact dimensions, they can easily be integrated in applications with limited space:
Technology: Ultracapacitors / Liquid-cooled
Energy content: 690 – 4,140 kJ
Power output: 100 kW / 200 kW
Dimension (W / D / H): 800 / 600 / 2,000 mm
Scalable system
The LES 300 can be scaled within its cabinet: Energy contents from 690 kJ to 4140 kJ are possible as well as power outputs of 100 kW or 200 kW.
Both systems, the LES 300 and LES 200, can be connected in parallel up to ten times.
The System includes:
- Storage units
- Converter unit
- Cooling
- Control
Power density and safety
Liduro Energy Storage – LES 200: The systems have well thought-out protection concepts: In the event of a fault, an isolating unit with fuses and switching contacts separates the storage from the power supply.
The housing of the LES 200 combines utility and design. Dust and water do not pose any problem. The connection unit of the power cables and the plug interfaces are correspondingly sealed, this allowing both indoor and outdoor operation.
Technology: Ultracapacitors / Liquid-cooled
Energy content: 1,500 kJ
Power output: 100 kW
Dimension (W / D / H): 750 / 1,120 / 1,100 mm
Liebherr, durable and robust – Liduro
Reliability and application safety: The highly efficient storage and reuse of recuperation energy provides for maximum reliability and operational safety during network fluctuations and prevents applications from malfunctions related to the network supply.
Low2no maintenance: The Liduro Energy Storage system is a low2no maintenance product based on its design, quality and protection concept. It is water-cooled and hardly includes wearing parts.
Easy integration: The mechanical and electrical integration of the complete system in an application is easy: Including the storage, converter, controlling and cooling units, only the electrical power cables as well as the power supply and cooling need to be connected.
Lithium-ion batteries
Liduro Power Port: The battery-based energy storage system is an easy to use integrated or stand-alone power source for electric vehicles and machines on off-grid construction sites or sites with limited grid access.
