In the latest evolution of Sheffield’s proud history as a leader in industrial steel production, the city that invented stainless steel has now forged a new agreement, which will see heat reclaimed from the Marcegaglia Stainless Steel melting shop and distributed into E.ON UK’s local district heat network. The move will bring more low carbon heating to homes and businesses across The Steel City.
The new agreement – a Memorandum of Understanding (MoU) – develops E.ON UK’s existing district heat network in Sheffield’s Lower Don Valley and utilises waste heat, a by-product of the stainless melting process.
Once operational, the collaboration will play a critical role in enhancing the resilience of the Lower Don Valley region’s energy infrastructure, while also contributing to Sheffield City Council’s decarbonisation goals and aligning to wider UK Government policy around Heat Network Zoning, where the city was identified as one of six pioneers.
“This agreement with Marcegaglia marks a major milestone in our efforts to accelerate the energy transition and expand sustainable energy solutions for the City of Sheffield,” said Vijay Tank, Chief Commercial Officer of E.ON Energy Infrastructure Solutions.
“By leveraging Marcegaglia’s expertise and infrastructure, we are forging the foundations for a greener, more resilient energy future that will create a crucible of benefits, including green jobs, increased skills and warmth within the local community.”
Liam Bates, President of Long Product at Marcegaglia, added, “As a company committed to improving its sustainability, this partnership allows us to enhance our energy efficiency and contribute to the decarbonisation of the region. We are proud to be part of a project that not only supports our own sustainability goals but also plays a key role in advancing city-wide energy resilience.”
The partnership is a significant step in E.ON UK’s ongoing efforts to develop city-wide district heating solutions, and it signifies Marcegaglia’s dedication to contributing to the global transition to a low-carbon economy.
