Next Stage of District’s Proposed Energy Network Heats Up
One of Kirklees Council’s key carbon reduction projects reached another milestone in its journey today. Approval by councillors at Cabinet will now enable the Heat Network project to progress to the next phase.
What is the Energy Network?
Huddersfield District Energy Network (HDEN) is considered key infrastructure to help the district achieve its ambitious target of net zero carbon emissions by 2038. A target set by the council when it declared a Climate Emergency in 2019.
The system, which features a network of underground insulated pipes, distributes heat in the form of hot water from a centralised heat generation plant to different buildings. These buildings are provided with space heating and hot water from the network instead of via traditional individual gas boilers.
Additionally electricity will also be delivered to buildings via a separate electricity network referred to as ‘private wire’.
Where will it be built?
The existing Energy-from-Waste (EfW) plant, located in Huddersfield, presents an ideal opportunity as a central heat and electricity generation plant. Harnessing the heat already produced there for the network. A separate energy centre, proposed at a nearby council owned site, would house pumps and vessels to store the heat. This would be in the form of hot water, as well as helping to smooth any demand from the network. It will also contain back-up gas boilers for providing heat during periods when the EfW is offline. This could be due to planned maintenance or unexpected outages. Back-up electricity would be provided via the national grid.
What are the benefits?
If the scheme is ultimately approved and constructed it is expected to achieve significant carbon emission savings of around 70%. This is when considered against typical individual gas boilers, over the lifespan of the scheme. In addition air quality improvements, through the removal of the need of natural gas-fired boiler plants at sites that would be able to connect to the network.
Heat network piping can also last over 50 years and has the ability to accommodate different sources of heat. So if an existing energy source reaches end of life, it can be removed from the system and replaced by a new source. This makes the system even more sustainable adding to its environmental credentials.
Contributions to other Council regeneration
The timing of the upcoming procurement process for the Recycling and Waste contract renewal has also been recognised as an important opportunity to the council and will play a key role in the heat network project. Work will be undertaken by relevant council officers to align these two projects to ensure mutually beneficial outcomes. Additionally other significant council-led redevelopments via the Huddersfield Blueprint and Station to Stadium schemes where possible would also connect to the network.
Councillor Naheed Mather, Cabinet Member for Environment and Councillor Will Simpson, Cabinet Member for Culture and Greener Kirklees said:
“District Energy Networks are recognised by central government as one on the most effective ways of decarbonising the local heat supply in urban areas.
We recognise the challenges of a changing climate facing the district and are making changes to meet the important target of net zero in 2038 for the benefit of Kirklees residents, its wildlife, landscape and biodiversity.
The scheme – managed by the Council’s Air Quality, Energy and Climate Change Team – would make a considerable dent in the decarbonisation of Huddersfield Town Centre and contribute significantly in making our district greener and carbon neutral by our 2038 target. We would like to thank officers for all the work that has gone into the project to date to gain approval for the next stage of project.”
How will funds be raised?
Now approved, additional funding is required to progress the project to the next stage. The team hope to raise this through a bid to the Green Heat Networks Fund (GHNF), launched by the government in March. The council have previously benefitted from funding for the various stages of the project . This included £300k for the delivery of the outline business case from the BEIS Heat Network Delivery Unit who have since shown their written support of the scheme to progress to the next stage.
With Cabinet approval the team await the outcome of the bid to the GHNF due later this year. If successful officers would start work on developing the full business case.
