The UK arm of Swedish energy company Vattenfall is looking to expand its plans to help Scotland heat homes in a more environmentally-friendly way. The test case is Midlothian Energy, a joint venture between Midlothian Council and Vattenfall Heat UK, which is working on a long-term business plan to invest £100m in energy projects over the next five years. They have employed Stirling-based FES Group to deliver low-carbon heating for around 3,000 homes, several shops, and a new school at Shawfair Town, a new development in the north of the Midlothian Council area.
Utilizing Waste Heat for Sustainable Heating
The project aims to capture heat that would otherwise be wasted at the Millerhill recycling and energy recovery center, operated by FCC Environment. This heat will then be transported via a network of underground pipes to provide heating and hot water for properties at Shawfair. Vattenfall’s modeling suggests that the heat networks in Midlothian could reduce emissions by up to 90% compared to individual gas boilers fitted in every home. Additionally, this low-carbon heating solution will reduce consumer and business exposure to gas price volatility.
The initial phase of the network involves laying approximately four kilometers of pipes, with completion expected by next June. This project is estimated to save over 2,500 tonnes of CO2 per year, equivalent to taking 1,200 cars off the road. The Scottish Government’s Low Carbon Infrastructure Transformation Project is providing £7.3m of funding for this initiative.
A Catalyst for Regional Network Expansion
Vattenfall’s first heat project in Scotland is seen as a catalyst for a wider regional network stretching across the Lothians. Eoghan Maguire, director for Scotland at Vattenfall Heat UK, expressed the company’s desire to grow the Midlothian region network, highlighting that heat networks are not limited by local authority borders. Vattenfall has a business plan for £120m of investment in the area.
Construction has already begun on the facility beside the energy-from-waste plant, with developers aiming to complete the outer shell by November. Around half of the pipe network for Shawfair has been laid, and more pipes will be installed as roads are developed for the new homes. Maguire explained that district heating, which involves moving waste heat through a network of hot water pipes and heat exchangers, is a proven technology. The unit in people’s homes is no bigger than existing gas boilers.
Addressing Scotland’s Carbon Emissions
Decarbonizing heating is a significant challenge, as it accounts for around 14% of Scotland’s overall carbon emissions. Vattenfall’s waste heat capture project presents a unique opportunity to utilize waste heat from the Millerhill facility, where waste is burned to generate electricity. By capturing the heat emitted from the chimney and delivering it as water and space heating to Shawfair, Vattenfall aims to contribute to Scotland’s carbon reduction goals.
Midlothian Council has been proactive in addressing climate change, being the first local authority to sign Scotland’s climate declaration in 2007. In 2019, the council declared a climate emergency, leading to the partnership with Vattenfall in the following year.
Expanding Low-Carbon Heating Beyond Midlothian
Vattenfall is not only working on the Midlothian project but also collaborating with Bristol City Council and Brent Cross near London. In Bristol, Vattenfall plans to invest £300m over the next five years to develop similar low-carbon heating networks. The company is also working on heating around 7,000 homes in Brent Cross and building a city-wide network.
While Vattenfall acknowledges the effectiveness of air or ground-source heat pumps, the company believes that district heating has an advantage in denser, urban areas close to factories that generate waste heat. Both technologies are crucial in achieving net-zero targets. Vattenfall emphasizes that retrofitting existing networks is possible, citing the example of Amsterdam, where a district heating network was gradually installed in both new and older properties.
Building Relationships for a Sustainable Future
Vattenfall recognizes the importance of building strong relationships with the supply chain, local authorities, consumers, and businesses to ensure the success of low-carbon heating initiatives. The company aims to educate stakeholders about the benefits of district heating and garner support for sustainable heating solutions.
With its ambitious plans and commitment to reducing carbon emissions, Vattenfall is playing a significant role in Scotland’s transition to a greener and more sustainable future.
