For the latest news, follow us on Twitter: @CI_EnergyMan, Facebook or LinkedIn PROJECT TO TURN SEWAGE WASTE INTO CLEAN FUEL FOR VEHICLES


Researchers from Coventry University are collaborating with Severn Trent and the Organics Group to turn sewage waste into a clean fuel for tankers and other vehicles. Severn Trent currently destroys the waste ammonia present in sewage due to its toxic properties but this programme of work could see it captured and converted into hydrogen. The benefits of the process are twofold – firstly,


Severn Trent will gain a more efficient method of processing ammonia; and, secondly, hydrogen will be produced as a clean fuel. If trials are successful, Severn Trent has the potential to recover up to 10,000 tonnes of green ammonia from its wastewater treatment plants, which could be converted into 450 tonnes of hydrogen. The Organics Group will be responsible for


developing an ammonia-stripping unit, recovering the chemical from the sewage waste at Severn Trent’s facility. Coventry University researchers will then seek to convert this into hydrogen by forming a purified electrolyte from the ammonia, which could be processed to create nitrogen and hydrogen gas. Dr John Graves, associate professor at the


Institute for Future Transport and Cities, is leading the university’s contribution. He said: “We are delighted to be part of this groundbreaking initiative with Severn Trent and Organics Group. The project will enable us to demonstrate that ammonia, which to date has had to be regarded as a waste product, could be processed in a more environmentally-friendly manner with the benefit of producing hydrogen, which has a number of


useful applications. These include its use as a potential fuel for heavy vehicles that may not be suited to battery electrification.” Peter Vale, technical lead in Severn Trent’s


Innovation team said: “We are thrilled to be collaborating with Coventry University and Organics Group on this potentially transformative project that will help us move towards a more circular approach to treating wastewater on our sites, and deliver on our net zero carbon commitments.” This project forms part of REWAISE, a €15m


initiative funded by the EU Horizon 2020 programme. A consortium of 24 organisations lead REWAISE, providing expertise across the water management and academic sectors with the aim of developing a carbon-neutral water cycle. www.coventry.ac.uk


RESPONDING TO THE DEMAND FOR GRID FLEXIBILITY


Smarter Grid Solutions (SGS) has responded to the growing demand for grid flexibility with the release of ANM Strata 3.1, the latest development of its flagship distributed energy resources management system (DERMS) product. The product launch comes at a time when changing energy use caused by national lockdowns has highlighted the need for more flexibility from distributed energy resources (DERs). Currently, the UK’s flexibility market is underdeveloped,


meaning it is difficult for the grid to respond quickly to unexpected changes in energy consumption. Between March and July 2020, it cost National Grid ESO an unprecedented £718 million to balance supply and demand, revealing the vulnerabilities of a system which is not agile enough for the changing energy landscape. The new version of SGS’ DERMS software will make


it quicker and easier for utilities and DER asset fleet operators to deliver flexibility services. Thanks to enhanced cloud deployment capabilities, the product can be rolled out to a wider range of clean energy operators, including those managing resources in electric heating and cooling, renewable generation,


W


energy storage and smart EV charging infrastructure. These capabilities, which allow cloud-based dispatch of grid flexibility services, have already been tested with UK distribution utilities. Euan Davidson, chief technology officer at SGS,


said: “ANM Strata 3.1 is our answer to the high demand for more flexibility in the energy market. We need solutions to manage rapid changes in supply and demand quickly and effectively, and the updates we have made to our software are designed to achieve exactly that. “This new version gives utilities and DER operators a


very high level of control over their distributed energy assets, allowing for precisely targeted instructions to be sent to individual units to increase or decrease power output, delivering exactly what’s required from each one. Having such granular control will allow users to extract value from resources when demand is high and avoid unnecessary waste of energy when it is low. Improving the flexibility of clean energy resources will not only boost the viability and economic case of the net-zero future, but will build much needed resilience into the electricity grid.” www.smartergridsolutions.com


elcome to the Spring issue of Energy Management. Net


zero is one topic that is becoming ever more important, and one step towards this is the growing adoption of electric vehicles. The UK Government has recently


announced that the sale of new petrol and diesel cars will come to an end by 2030. But while sales of electric cars are improving, there are still many factors that are slowing its uptake, including range anxiety. In our Electric Transport focus this month we cover a number of interesting areas – the first of which looks into EV efficiency, but also questions whether recent developments mean that, one day, hydrogen vehicles will dominate the market instead (see page 13). It has also been interesting to see how electric buses are being used


more across the country – in fact Arrive Merseyside is now running these on some of its routes as it heads towards its commitment to make its business carbon neutral by 2030, while reducing its impact on air quality in urban centres (please turn to page 14). Other interesting areas covered in this issue are boilers, pumps &


valves; bio-energy; efficient products; purchasing utilities; and monitoring & metering.

EFFICIENTLY BAKING PET TREATS


A Babcock Wanson BWD40 Fire Tube Boiler has been installed in the Real Petfood Company’s manufacturing facility in north east Wales, where it is being used to heat retort cookers and mixing vessels for high quality baked semi-moist pet treats and super premium biscuit products. The Boiler was chosen as the heat


source due to its high efficiency, long life and low cost maintenance. Efficiency comes as a result of the optimised matching of the boiler shell and the burner, along with advanced burner head geometry which provides stable combustion with near constant efficiency throughout the complete burner modulating range. Efficiencies of 95% have also been achieved with the installation of a Babcock Wanson matched economiser. www.babcock-wanson.com


SIMEC Energy, part of the GFG Alliance, has partnered with intelligent energy technology and flexibility leader GridBeyond to participate in the GB Frequency Response Market, helping National Grid balance and decarbonise the energy network whilst generating substantial savings. Ian Love, Power and Hydro


manager at SIMEC Energy, commented: “This is a fantastic partnership and one which both benefits the National Grid and enables SIMEC Energy’s assets to provide more renewable energy, cementing GFG Alliance’s commitment to be carbon neutral in 2030.” www.simec.com/energy/


Recognising the urgent need to make net zero a reality, Centrica has announced that it will accelerate its commitment to be net zero by 2045, five years ahead of its previous target and the UK deadline. The company has also announced a new commitment to helping its customers be net zero by 2050. The reduction in Centrica’s


own emissions (scope 1 and 2) and those of its customers (scope 3) align with science-based targets and the actions required to limit warming to 1.5°C. www.centricabusinesssolutions.com


Schneider Electric has announced it will electrify 1200 vehicles by 2025 for its own fleet. The commitment marks a significant step towards making the most sustainable company even closer to carbon neutrality. This will enable Schneider to


directly reduce its climate impact by preventing the creation of 64,400 metric tons of CO2


emissions per


year by the end of the transition. www.se.com/ww/en/
