Cory’s heat-main plan: how to make it happen

As from 2027, Cory’s Riverside energy-from-waste facility, consisting of two units, Riverside 1 (800 000 t waste/y) and 2 (650 000 t waste/y), located at Belvedere on the River Thames, UK, will treat more than one-third of London’s residual waste, which would otherwise go to landfill.
The process creates enough waste heat to supply 400 000 homes, says Cory, which is developing a long
Cory’s heat main concept
distance “Strategic Heat Main”, which would enable this heat (initially drawn from unit 1) to be supplied to users. A new paper from Cory and Stonehaven sets out a way this could be financed, helping to unlock around £5bn in investment.
Cory is also looking at adding carbon capture and storage at the Riverside site and has received approval for its Development Consent Order
application. Once captured, the CO2 would be
liquefied and transported via ship for permanent sequestration under the North Sea. “This use of a shipping solution draws on the company’s extensive maritime heritage and over 200 years of operating on the River Thames,” Cory notes. It would be the UK’s largest WECCS (waste-to-energy with CCS) project.
Valmet’s advanced heat recovery technology improves boiler efficiency
Valmet says it is joining Veolia’s HeatUp! Project in Poland, which aims to add an innovative heat recovery system to a biomass fuelled fluidised bed boiler at the EC4 combined heat and power energy efficiency and increase the production of renewable energy and thereby improve Veolia’s CO2
emissions footprint. Valmet will deliver the flue gas condensing heat recovery system for the project, plus automation technology. Start-up of the new facility is scheduled for the third quarter of 2027. The heat recovery system will extract more than 50 MW of heat from the boiler flue gases and provide it to the local district heating
with a “sustainable and future-ready solution” that is calculated to reduce carbon dioxide emissions by over 82 thousand tonnes per year. “The HeatUp! project, together with further investments planned in the near future – such as the construction of a gas-fired unit and a heat accumulator – guarantee a complete from 2031 and the transition of the entire district heating system towards a reduced environmental footprint.
The implementation of HeatUp! is part of Veolia’s strategic GreenUp programme, which sets ambitious decarbonisation goals and is said to be based on “organisational agility, operational excellence and advanced technological know-how.” Under this programme, Veolia has developed a comprehensive decarbonisation strategy system, of which HeatUp! is an
integral part and “clear proof that the chosen direction delivers tangible results.”
The project also represents an important step towards the long-term goal of climate neutrality in the energy sector, supporting coal phase-out, pollution reduction and the regeneration of natural and vice president of the management board of the Veolia Group in Poland.
“Thanks to the HeatUp! project, renewable heat production at EC4 will increase by one third without increasing the amount of biomass burned, while CO2
emissions will be reduced.
This investment is a key element of Veolia’s at phasing out coal, but also at ensuring long- term security of heat supply for local customers,” “By integrating condensing heat recovery with high-efficiency heat pumps, we enable Veolia to increase efficiency, reduce environmental impact, and provide sustainable district heating for the process technology from a single supplier ensures an optimised lifecycle performance,” said Lari-Matti Kuvaja, director, environmental solutions, pulp, energy and circularity, Valmet.

The flue gas condensing plant that Valmet is supplying to the project included three different flue gas condensing stages, designed to maximise heat recovery. The Valmet scope also includes a condensate treatment system to make use of the flue gas condensate for producing raw water for utilisation in plant processes. Valmet’s scope will also include extension of the existing Valmet DNA system at the plant to the new heat recovery equipment.
