Select Plant Hire and PUNCH Flybrid are pleased to reveal the latest results from its innovative flywheel energy storage system, which is set to save over 80 tonnes of CO2 being released into the atmosphere and over 30,000 litres of fuel every 3,000 hours.

Since launching the product back in September, additional testing has taken place over the last seven months which has seen a 66 tonne luffing crane on a London construction site carry out its normal operations with a 320kVA generator set, combined with the PUNCH Power 200, as opposed to a 800kVA generator set up.

The CO2 saving with the PP200 set up is the equivalent of the annual emissions of 55 passenger vehicles. These latest findings prove that by connecting the PUNCH Flybrid technology to the generator set, the flywheel load-levels the peak power that the generator set has to deal with. The PUNCH Flybrid system then delivers energy immediately at high power during an increasing load step and captures excess energy during a decreasing load step.

Alex Warrington, Select’s Managing Director, said: “It is quite staggering when you see the environmental savings this technology can have on just one crane. At Select we are proud to be leading the way in something that could easily be integrated to cranes not just across the UK, but the world and make a significant impact on CO2 pollution.”
