Heat pump technology supported by heat networks investment project

Following the publication of the Heat and Buildings Strategy, Triple Point Heat Networks Investment Management has announced funding awards to a suite of low carbon heat network projects.

Heat networks have been identified by the Government as a key technology and the Strategy placed particular emphasis on the use of heat pumps in the delivery of low carbon heat.

The announcement combines the two technologies across four projects. The variety of projects that have secured funding are said to demonstrate the adaptability and flexibility of heat pump technology when deployed in heat networks.

The successful heat network schemes announced today all utilise heat pump technology and bring the total amount awarded via the Heat Networks Investment Project to over £250 million.

Ken Hunnisett, Triple Point Heat Networks Investment Management said:
“The Heat and Buildings Strategy made clear that both heat networks and heat pumps are central to the Government’s decarbonisation efforts. So, it is fantastic to see so many schemes already stepping up to combine these solutions in such innovative ways to access heat under our feet, in the air around us, in our waterways and even within our sewerage system. Not only will these inspiring projects deliver carbon savings, but they prove that heat pump technology is adaptable and can contribute to a smarter, more flexible future energy system.”

Lord Callanan, Department for Business Energy and Industrial Strategy said:
“Changing the way we heat our homes and workspaces is key to tackling pollution and today’s investment into new heat networks across Worthing, London, Bristol and Liverpool will ensure these areas are placed at the heart of the UK’s green industrial revolution.
“The new networks of air source heat pumps will deliver affordable, low-carbon heat and energy across the nation’s homes, universities residences, and business units, while opening up huge job and investment opportunities, making our thriving cities and seaside towns greener places to live, work, and visit.”

Overview of projects awarded funding

Kensington and Chelsea Council has been awarded over £1.1 million to develop a new zero carbon heat network which will be able to provide heat to 826 existing homes in North Kensington, and several public buildings and business units.

Worthing Borough Council’s pledge to become carbon neutral by 2030 by replacing gas boilers in 27 buildings with a heat network that will use a centralised heat pump to take heat from the sewer underneath the town. The use of ‘sewer heat’ to replace gas boilers follows a discovery that sewers below Worthing contain more than enough heat to replace gas boilers in public buildings.

Bristol City Council has previously been awarded HNIP funding for two heat networks in the city and has secured a further £1.7 million to support the development of a new heat network. Combined, these low carbon networks are expected to deliver heat to over 6,000 residences.
The Temple Heat Network is being developed to generate low carbon heat from water sources accessible from the regeneration of Temple Island and waste heat from the University of Bristol’s Temple Quarter Enterprise Campus.

Peel NRE, through its supply company (ESCo) Mersey Heat are delivering a district heat network to the Liverpool Waters development and the surrounding areas. Peel NRE, part of Peel L&P, successfully secured funding in Round 2 to deliver the first phase of the Mersey Heat network. The scheme was initially designed on a Gas CHP generation; however, this new HNIP funding award of £6.2 million will enable the transition to a heat pump solution as the main generation source and connection of a central cluster of existing buildings with significant load (Liverpool’s The Three Graces buildings and surrounding properties). The funding will support one of two 3MW low-carbon heat pumps, the first of which will be water source heat pump.
