Xergi has signed agreements to supply two of its first biogas plants. Xergi has signed contracts to supply two Anaerobic Digestion (AD) plants to the British company Tamar Energy. These plants are among the first projects in Tamar Energy’s overall plan for a network of more than 40 biogas plants across the UK, with a total capacity of 100 MW and producing enough energy to power more than 200,000 homes.“We are very proud that Tamar Energy has chosen Xergi as its supplier. Tamar Energy is an extremely strong player dedicated to promoting biogas production in the British market,” says Xergi chief executive officer Jørgen Ballermann.Tamar Energy was set up in February 2012 with a capital base of almost GBP 100 million – with an unparalleled focus on generating green energy using AD.Investment has come from a number of influential shareholders, including The Duchy of Cornwall, the Rothschild family and RIT Capital Partners, Dubai-based investment company Fajr Capital, the Tamar Energy Executive Management Team and Sainsbury’s, who is also a strategic operating partner.“We have built up good relations with Tamar Energy over an extended period of time, and there is no doubt that the company will play a very important role in the British biogas market in the coming years. This is why the contracts are so strategically important to Xergi,” states Jørgen Ballermann.Dan Poulson, engineering and strategy director, Tamar Energy, added: “Tamar Energy is a company focused on AD and obsessive about quality, delivery and advancement in every aspect of what we do. So we’re very proud to work closely with Xergi as a partner that shares these values with us.”Its project in Retford, Nottinghamshire is to use Xergi’s NiX® technology. This patented technology makes it possible to digest large quantities of poultry manure in a biogas plant.“Poultry manure contains high levels of nitrogen. This impedes the biological process in the digester which means that most standard biogas plants are not capable of processing large quantities of poultry manure. However, Xergi’s NiX® technology removes some of the nitrogen before the poultry manure is added to the digester,” explains sales manager Jørgen Fink from Xergi.In addition to poultry manure, the Retford AD plant will also be processing vegetable waste and maize silage. The plant will have the capacity to generate 3 MW of electricity and is expected to be commissioned in January 2014.The other project in Holbeach in Lincolnshire is located close to one of the region’s largest potato producers and processors. This plant will process vegetable waste and maize silage and will have the capacity to produce 1.5 MW of electricity. The plant is scheduled to be commissioned in December 2013.
