Black Dog Biogas, the owner and operator of an anaerobic digestion plant near Newport on the Isle of Wight, has completed commissioning of a private wire to supply renewable electricity to Vestas’ neighbouring wind blade manufacturing facility.
The project, led by Black Dog Biogas and its manager Earth Capital, will supply low-carbon electricity to Vestas’ 221.2k sq ft plant.
The facility employs over 600 people and produces 80m long blades for installation on offshore wind projects globally, particularly in the UK.
Vestas will use this renewable electricity to manufacture offshore wind turbine blades that will generate low carbon power in wind farms across the world for decades to come.
Black Dog Biogas generates renewable electricity through anaerobic digestion.
Organic matter, such as maize and grass, in this case 100% sourced from the Isle of Wight, are broken down by enzymes to produce biogas and biofertiliser.
Black Dog uses the biogas as a fuel in two combined-heat-and-power units to generate renewable heat and electricity.
The nutrient-rich biofertiliser is spread back onto the Isle of Wight’s arable farmland and helps to grow more crops for both the Black Dog facility and promoting sustainable agricultural practices.
This helps support a circular economy and avoids the use of carbon intensive fertilisers.
Black Dog Biogas expects to generate sufficient power to supply around 80% of Vestas’ needs, as well as around 1200 homes on the Isle of Wight.
Earth Capital has invested in Black Dog Biogas through the firm’s Nobel Sustainability Fund.
This is a multi-phase, multi-geography fund, which invests across the sustainable and impact private markets, accelerating companies for growth, expansion, and subsequent acquisition.
Vestas’ Isle of Wight facility senior factory director James Luter said: “The UK Government has unveiled ambitious plans to expand the country’s offshore wind capacity, potentially powering all UK homes by 2030.
“Our factory has an important role in helping to make that ambition a reality.
“It’s particularly pleasing that we can deliver our blades to the UK and global markets sustainably, using renewable energy from Black Dog to manufacture our blades.”
Director of Black Dog Biogas & investment director of Earth Capital Dr Simon Crook said: “This is a great opportunity for two neighbouring green businesses to deliver a scheme that both makes environmental and commercial sense.
“We could not have wished for a better partner with which to deliver this project.
“Collaborations such as this are vital in helping the UK reduce carbon emissions and embrace renewable energy.
“Biogas is an important part of the low-carbon energy mix and it has the potential to reduce waste to landfill by converting household food waste into energy as well.”
