Getting larger grid connections is challenging, while running generators is expensive and polluting. Tower cranes and hoists demand high power but consume little energy — an inefficient grid usage. This is where we enable you to make a difference. Because project delays are not an option.
- Limited grid capacity
- Inefficient and costly diesel consumption
- Project delays & higher costs
- Tighter zero emissions rules
Common challenges
- Reduce your site’s overall power demand
- Minimise or eliminate fuel use from generators
- Peak shave multiple cranes and hoists at once
- Cut down costs on power infrastructure
- Reduce your site’s overall power demand
What we can do for you
Energy storage solutions
THOR Flywheel
Peak shave your construction site with flywheel technology. Our kinetic battery can reduce the maximum power demand of one or multiple tower cranes and hoists by up to 80%, giving you total control, lower costs, and a smarter path to a cleaner build.
CRYSTAL Battery
CRYSTAL is equipped for sites with high base-loads, long runtimes, and limited access to strong grid connections. Want to get rid of generators? Our Sodium-ion battery matches lithium performance but uses safer, more abundant materials — making it the future of sustainable construction energy storage.
Uptake of electric port cranes, shorepower facilities and electric machinery is driving up power demands, straining local electrical grids. Not optimizing your power needs means huge investments in grid capacity, long lead times and unreachable sustainability ambitions. Ports need to become energy experts to be able to conduct their business in the future.
- High peak power demand from port cranes and equipment
- Limited grid capacity or costly infrastructure upgrades
- Stricter zero-emission and sustainability targets
- Inefficient generator fuel consumption for microgrid-based ports
Common challenges
- Reduce power demand of your electric port cranes by 60 to 80%
- Minimize or eliminate CAPEX need for grid upgrades

- Free up capacity in your existing grid connection
- Lower fuel consumption on generator-based port microgrids

Energy storage solutions
THOR Flywheel
Our THOR Flywheel has near unlimited cycling capacity and can function as the shock-absorber and peak-shaver for other storage systems and the energy systems as a whole. The technology excels in delivering frequent, high power peaks for high power applications. This helps smoothen load curves for slower responding energy sources and enables frequency regulation to maintain a high power quality on site.
ZEUS Hybrid
The ZEUS container makes your microgrid more efficient and resilient. This hybrid energy storage system combines the high power and cycling capabilities of the flywheel with the cost-efficient energy storage properties of the sodium-ion battery. Our integrated solution manages short, high-power peaks and provides reliable backup from the same unit — ensuring stronger grid stability, fewer outages, and more efficient use of renewables.
Energy flexibility is vital to efficiently balance the dynamic supply and demand within a microgrid; without energy storage, it's incredibly difficult and costly to manage the fluctuating power demands that are inherent to your microgrid. Energy storage enables generators to run more efficiently and smooths out intermittent renewable energy. This makes energy storage a fundamental necessity.
- Not unlocking full potential of Solar PV
- High OPEX due to inefficient generator use
- Wasting fuel on unoptimized power demand
- Voltage fluctuations
- Blackouts
Common challenges
- Reduce your fuel consumption
- Lower your OPEX
- Improve your energy resilience
- Enhance your power quality
- Eliminate unnecessary generator start-stops
