Actions and Implementation
1. Transition to HVO Fuel: Mackenzie Construction switched to Hydrotreated Vegetable Oil (HVO), reducing the consumption of high carbon-emitting diesel. This green fuel powered all onsite plant, equipment, and generators. We have made this mandatory for all Scottish Water sites.
2. Battery Storage Systems: These systems, charged during the generator's operation, intelligently powered site accommodation, and charged electric vehicles and plant equipment. This maximised energy storage and efficiency when burning HVO. By using the telematics, we can get a better understanding of the way each item is operating, and its power requirements. This can support the development of an assessment of ‘breakeven’ to allow the shift to new power sources as soon as is viable.
3. Aluminium Trackway System: Instead of the high-carbon activity of creating a traditional access road, Mackenzie opted for an aluminium trackway system. This drastically cut down on the fuel consumption and carbon emissions typically associated with temporary road construction.
4. Hydrogen-powered CCTV Security Units are being used on-site and are a much greener alternative to fossil fuel, another benefit is that they don’t need to be powered by generators meaning that there is no noise pollution whilst having live CCTV on-site at night.
