Low carbon buildings


www.heatingandventilating.net Biocoal facility to


cut emissions L


eaders in the smokeless fuel industry are to develop a new £4m facility capable of producing next-generation biocoal to reduce


greenhouse gas emissions. CPL Industries, manufacturer of smokeless coal, together with The University of Nottingham and the Energy Research Accelerator (ERA) is using new technology known as Hydrothermal Carbonisation (HTC) which mimics the long-term natural process of coal formation. The technology will convert high- moisture biomass, including food waste, into next-generation solid fuels with coal-like properties. The process, which will be managed by CPL at its manufacturing plant in Immingham, North Lincolnshire, takes a matter of hours rather than millennia. The HTC method allows for the mass production of a high-energy, low-carbon biofuel for domestic and industrial uses, offering a solution to the issue of air quality. Production is scheduled to begin this summer.


Speaking about the new facility Tim Minnett, CEO


of CPL, said: “The technology has the potential to revolutionise the treatment of high-moisture organic waste streams, producing value-added products that displace fossil fuels and promoting the circular economy. CPL and the rest of the project partners stand ready to engage with local authorities and waste managers to source suitable waste material, conduct trials and develop the wider commercial and environmental benefits.” The new facility is being co-funded by ERA, a


consortium of six Midlands universities and the British Geological Survey (BGS), which has investment from the government’s innovation agency, Innovate UK, to research and demonstrate low carbon technologies.


The technology has been supplied by Spanish


company Ingelia; the intention for the HTC facility is to investigate suitable replacements for fossil fuels in CPL’s home heating products, with possible future developments being the replacement of coking coals in industrial applications such as foundries and smelters.


CPL is working with Professor Colin Snape at the


University of Nottingham, who is director of the Centre in Efficient Power from Fossil Energy and Carbon Capture Technologies. Professor Snape added: “This new HTC facility is the first such plant in the UK, enabling us to look at how we can convert waste streams into value-added fuel products that have many domestic and industrial applications. Also, by using the biocoal that has been made from biowaste, we are producing a carbon-neutral fuel and reducing greenhouse gas emissions.”

University of St Andrews’ energy centre


S


pirotech vacuum degassers are helping Scotland’s oldest university with its ambition to become carbon neutral for its


energy usage. The units have been installed in the former 19th-century Guardbridge Paper Mill, now transformed into an ultra-modern energy centre serving the North Haugh campus of the University of St Andrews in Fife. The degassers remove dissolved gasses in the


system’s installation fluid by temporarily subjecting a portion of the water to underpressure, or vacuum. The released air is then separated and


expelled. By continuously repeating the process 99.9% of the gases are released and removed. If left to circulate the air would adversely affect the system’s efficiency, impacting on flow rates and causing corrosion. In turn, this could lead to dirt build-up, maintenance problems and higher energy costs. In the long-term even system breakdown. The energy centre is at the heart of the £25 million University of St Andrews Biomass District Heating Project, which was designed, built and operated by energy generation and


district heating specialist Vital Energi. A key element in the university’s ambition to be the UK’s first carbon neutral university for its energy usage, is the 10-metre high 6.5MW boiler from which the energy centre generates hot water. The water is then distributed through a network to the campus where it provides low-carbon heat and hot water. The energy centre is capable of pumping hot


water through a 10.6km district heating network serving 35 buildings. Spirotech vacuum degassers are designed for use in large commercial systems with many branches and low flow rates, where ‘ordinary’ dearators are not sufficient. Rob Jacques, Spirotech’s national key accounts and technical sales manager, said: “When specifying for a heating, or cooling, system it is important to remember the conditioning of the water is a critical factor in the final efficiency, effectiveness and lifespan of the installation. “It’s very rewarding to know our vacuum degassers are making a contribution to one of the largest biomass and district heating schemes in Scotland at one of the country’s leading research institutions.”
