The Revolution Battery replaced a diesel generator saved over 750 litres of diesel per week, preventing the emission of 2 tonnes for CO₂ per week. It also cut costs, reduced noise and improved air quality.
Revolution Battery is an industrial battery energy storage system (BESS) which breaks the link between energy storage and output power. This innovative battery system incorporates a battery pack which can deliver high amounts of power from a comparatively small amount of energy storage. This results in a smaller battery system with much reduced use of battery cells, higher efficiency and lower embedded emissions. Dumarey Green Power produces its Revolution Battery in the UK, utilising local labour & suppliers as well as minimising transport emissions in the large UK construction market.
Launch customer Falcon Tower Cranes immediately deployed their first Revolution Battery to a Bowmer + Kirkland construction site in Nottingham, where the system was set to work powering a Jaso J118pa and a Jaso J138A tower crane. Traditionally, these cranes would have been powered from a 200kVA generator. Such a large generator results in significant CO₂ and other local emissions.
Instead of the large diesel genset, the Revolution Battery allows these cranes to be powered from only a 32A mains connection. As a result, Dumarey Green Power calculated that the Revolution Battery would save over 2,000kg of CO₂ per week.
Daily energy throughput for the first week averaged 92kWh per 10-hour day which corresponds with an average loading of just 4.6% on the proposed 200kVA generator. This highlights the chronic underloading experienced when using diesel generators on cranes, and such low levels of loading are associated with a range of reliability issues. These issues are compounded when Stage V generators are deployed, as these can also suffer from particulate filter regeneration issues and problems with the SCR (AdBlue) systems.
The introduction of the Revolution Battery delivered impressive savings in just the first month:
High Power low energy battery energy storage system, ideal for tower cranes
The system replaced a diesel generator with a small 3-phase mains supply
Removing diesel generators eliminates fuel deliveries, reduces noise and improves local air quality
The Revolution Battery Runs 24 hours per day, 365 days per year enabling unlimited crane operations when required
litres of diesel saved each week
tonnes of CO₂ avoided each week
ZERO NOISE,
on site emissions, fuel deliveries
