| Power from waste and biomass enfineum selects HZI for Skelton
Construction is now underway on enfinium’s 49 MW Skelton Grange waste-to-energy facility in Leeds, West Yorkshire, UK, following financial close in July. HZI (Hitachi Zosen Inova) is EPC contractor. It is HZI’s fourteenth energy-from- waste project in the UK.
Skelton Grange is a combined heat and power facility. It will process 410 000 t/y of residual (post-recycled) waste (ie waste that cannot be reduced, reused or recycled). Full commissioning of the plant is planned for 2025.
Planning permission was given by Leeds City Council in March 2020 and an environmental permit awarded by the Environment Agency in December 2020. In January, enfinium Skelton Grange signed two long-term waste supply contracts, amounting to over 50% of the facility’s annual capacity, with SUEZ and Beauparc. Further long-term waste supply contracts were signed with Biffa and B&M Waste in June 2021. enfinium says it has had “a long and successful partnership with HZI, following the successful construction of nearby waste-to-energy facilities, Ferrybridge 1 and 2.”
The new EfW facility will be built on the site of the former Skelton Grange Electricity Works units, which were decommissioned in 1983 and 1994. It will have two incineration lines, which will be equipped with HZI’s own moving grate EfW technology. It will also include XeroSorp® multi-stage dry flue gas cleaning process.

enfinium describes itself as the “largest pure play waste-to-energy business in the UK”, and is developer, owner and operator of seven “strategically located” UK residual-waste-to-energy facilities in operation or advanced development, including two further CHP facilities, Kelvin (400 000 t/y) in West Bromwich and Kemsley North (390 000 t/y) in Sittingbourne, Kent. For Skelton Grange, enfinium was advised by Deloitte and Ashurst. Santander, MUFG, Natixis and Credit Agricole are lenders to the project and were advised by Linklaters.
enfinium brings together Wheelabrator UK and Multifuel Energy Limited to form a single combined company. Multifuel Energy Limited – developer of Ferrybridge 1 and 2, West Yorkshire – was a joint venture of Wheelabrator UK and SSE.

Ratcliffe regenerated, as EfW facility
Uniper has received planning permission for its proposed residual-waste-to- energy facility – the East Midlands Energy Re-Generation (EMERGE) centre – to be located at the Ratcliffe-on-Soar coal power plant site, UK.
Andy Read, EMERGE centre project manager for Uniper, said:
“With the required planning consents in place, we are now in a position to move forward with the project and start to deliver our wider vision for Ratcliffe – to move towards becoming a zero carbon technology and energy hub for the East Midlands region. The planning approval will enable £330 million worth of capital
infrastructure investment to be realised… The EMERGE Centre will be the first significant new development at Ratcliffe-on-Soar in over 50 years.”
Construction is expected to begin in late 2022, with the facility anticipated to become fully operational in 2025.
Why 40 modules are better than one
Spanner Re² reports installation of a 2 MWe wood fuelled plant in Azumino City, Japan, at Air Water Inc’s Azumino Biomass Energy Center. The facility is a trigeneration plant, producing heat for greenhouses and CO2
all peripherals, including biomass conveyor and fuel dryer.

tomato growing, as well as power. The facility, Spanner Re2’s largest to date, consists of no less than 40 wood gasification modules, connected in cascade configuration. Spanner Re2’s scope included

Operation of the power plant can continue while maintenance work is being carried out on individual modules – “a major advantage over conventional large-scale single systems that have to be shut down completely for maintenance work”, says Spanner Re2. Only local wood is used as fuel. This is processed into wood chips, which are then fed into the plant as needed, in a fully automated process.
Power supplied to the grid benefits from the Japanese feed-in-tariff for renewables.
