The CAGE Hybrid Gas Engine (HGE) is a novel generator technology developed and trialled on this construction site. It enables seamless switching between hydrogen, LPG, and (potentially) biomethane fuels, providing a flexible, low-emission alternative to traditional diesel generators. The system is designed for easy integration with site battery storage units and can be optimised for different gas fuels at the…
This contractor has used a dredger powered by liquefied natural gas (LNG). Making this choice provides a cleaner, more sustainable alternative to traditional marine gas oil (MGO), with emissions significantly reduced. There was a saving of up to 20% for CO2, up to 85% for NO2, and virtually eliminating SO2 and particulate matter. This supported compliance with strict environmental regulations…
Fuel consumption savings of up to 7.59% have been verified in a three-month series of trials with trucks owned by the demolition contractor using the product SulNOx Eco Diesel Conditioner. Following these results, this has now rolled out to 100% of the fleet. Based on 2024 fuel consumption data from the Jigsaw Fuel Management System and UK Government conversion factors,…
On this project there are two site compounds which were initially run using diesel generators. The diesel was switched to hydrotreated vegetable oil (HVO) as it was more sustainable and produced less emissions. However, the cost of HVO has increased and the emissions are comparable to white diesel when comparing well to wheel. The diesel powered generators were not running…
To move towards their Net Zero by 2030 goal, this contractor has deployed the Deep Green carbon-neutral welfare set up at their site . The unit is powered by an ultra-efficient solar panel electrical system with a back-up HVO generator, meaning the unit is powered by virtually 100% renewable energy and operates at a near-silent level. The unit also has…
On this project they have invested and continue to invest in the green spaces and wildlife areas in their development. Every roof is finished with a green or brown roof, along with logs piles and other habitats promoting wildlife. In 2020 the project won the prestigious Sir David Attenborough award for its commitment to enhancing biodiversity. Systems are in place…
This contractor is using a generator which uses glycerin as its power source. This is a waste product from bio diesel production and when consumed in the generator it provides mobile power with zero particulate emissions, it is also non-flammable, non-toxic and biodegradable and therefore has a very low carbon footprint. This is an example of beneficial reuse of a…
This project is reducing their carbon emissions by using an alternative fuel to diesel. They have started trialling the use of Green Diesel and Hydrotreated Vegetable Oil (HVO). HVO is a fossil free fuel made from 100% renewable raw materials and will be supplied to the project for use in both their generators and other plant machinery. Throughout the trial…
HVO is a high quality bio-based fuel which does not compromise the performance of the plant or engine, only improving the emissions related to plant operations within construction. Ferrovial trialled a HVO (Hydrotreated Vegetable Oil) renewable fuel as an alternative to traditional diesel. The HVO was trialled in a 17t wheeled excavator and it was compared against a 22t tracked…
At 21 Moorfields, we are trying to reduce our carbon footprint and minimise the disturbance to the local community who surround our central London site. Following this aim, we have decided to trial the use of a hydrogenated vegetable oil to fuel two generators on site whilst we transfer the mains power supply from low to high voltage. The ‘Green…
New passenger tunnels were required to be built between existing platforms at Kennington Station to cope with increased passengers numbers once the Northern Line extension to Battersea and Nine Elms becomes operational. The tunnels had to be completed within a 16-week window to minimise impacts on the network and works were required 24/7. Unfortunately there was insufficient power supply available…
Used cooking oil from the site canteen is collected by a specialist company who then transform it into biodiesel. This is used for powering diesel vehicles and also for heating. Any packaging related to the cooking oil is also recycled. The collection is free of charge and the company delivers fresh cooking oil at the same time as making the…
