Low carbon heat
Heat is the single largest source of carbon emissions in Scotland and the largest element of our energy demand. With the lowest rate of decarbonised heat of any country in Europe, Scotland is poised to rapidly scale up the expansion of its low carbon heat capacity and tech solutions.
Leading on climate change
Scotland is committed to decarbonising its economy for the benefit of our environment, our people and our prosperity. Scotland was the first country in the world to declare a climate change emergency and the Scottish Government has shown global leadership in setting world-leading targets.
75% reduction in emissions
Scotland has the toughest statutory target in the world for a 75% reduction in greenhouse gas emissions by 2030.
£2 billion public finance
has been allocated long-term to a new public investment bank to decarbonise Scotland’s economy.
£3bn green investment opportunity
launched by the Scottish Government to attract new low carbon investments into Scotland.
Scotland’s low carbon heat challenge
- Heat currently accounts for 52% of Scotland's energy demand and is the single largest source of emissions (41% indicative)
- Scotland's renewable electricity (as a percentage of gross consumption) is the second highest in the EU
- By contrast, at 5.9%, heat supplied by renewables in Scotland (as a percentage of gross consumption) is the lowest in the EU
- 80% of Scotland’s domestic energy used is for heating and hot water
- By 2032, 35% of domestic buildings must be heated by low carbon technologies
- By 2024 all new homes must use low carbon heating
Growing market opportunities for low carbon heat solutions
Heat pumps
To decarbonise heat, it’s estimated that more than one million heat pumps need to be installed in the UK each year by the mid-2030s, totalling 26 million by 2050.
The heat pump market in Scotland, including manufacturing, components, installation and servicing is set to ramp up to meet its ambition to become a net zero society by 2045. In the following webinar recording, John Maslen, project manager at ParkPower, summarises Scotland’s unique position and the wider ground source heat pump opportunity.
Heat networks
There are more than 800 district and communal heating networks in Scotland, supplying more than 25,000 households and about another 100 networks supply commercial and public sector buildings. Scotland has favourable locations for heat network development in urban areas with high density for regeneration.
If reducing emissions is the question, are heat pumps the answer? Scotland's low carbon specialists open the discussion in the following webinar recording:
Minewater geothermal
Using geothermal heat from minewater could help reduce Scotland's greenhouse emissions. With its ambitious climate change legislation coupled with the potential availability of 600km3 of disused mine workings in the Midland Valley (in theory meeting 8% of Scotland's domestic heating requirement and up to 40% of Glasgow's heat demand) Scotland has the potential to lead the world in minewater geothermal technologies.

Funding and support for low carbon heat projects
Strong government programmes and public funding will assure you of Scotland's commitment to driving market growth in low carbon heating, including:
- Scotland’s Programme for Government 2020 – a commitment to secure investment of £1.6 billion in heat and energy efficiency in our homes and buildings
- £120 million Heat Transition Deal – includes a £50 million Heat Networks Early Adopter Challenge Fund for local authorities and a £10 million fund to support hydrogen heat demonstrator projects
- Low Carbon Infrastructure Transition Programme (LCITP) – speeds the development and delivery of significant low carbon energy projects across Scotland
- District Heating Loan Fund – offers low interest unsecured loans of up to £1 million, with larger loans available on a co-investment basis
- District heating relief – rate relief guaranteed until 2032, providing certainty to investors
- Community and Renewable Energy Scheme (CARES) - offers a range of financial support to local energy and heat projects
Low carbon heat projects underway in Scotland
The Queens Quay is an innovative heat network in Clydebank that uses ground-breaking low carbon heat generation technologies, including harnessing heat from wastewater and large-scale water sourced heat pumps. It's Scotland’s largest single heat network powered by Scotland’s first large-scale river-based heat pumps.
The Glasgow Observatory provides an at-scale facility, open for research and innovation to explore the processes and impacts of minewater geothermal as a sustainable way of heating urban homes and businesses.
The availability of 600km3 of disused mine workings in Scotland’s Midland Valley could meet 8% of Scotland's domestic heating requirement and up to 40% of Glasgow's heat demand, providing an exciting opportunity for geothermal companies to innovate and grow here.
World first
UK’s new underground observatory in Glasgow is open for research
This is the first of two new underground laboratories in the UK and a world first, that will give scientists an unprecedented look at the subsurface of the Earth.
It comprises 12 boreholes, which are 16-199m deep and fitted with 319 state-of-the-art sensors.
Data from the observatory will help scientists understand how heat using warm water from abandoned mines could be used as a renewable energy source for homes and industry.
Research will contribute to the UK’s ambition to decarbonise its energy supply and achieve net zero by 2050.
"There is no other publicly-funded observatory like this in the world, and it is very fitting that it is located in Glasgow, which will host COP 26 next year."
Karen Hanghøj, executive director of the British Geological Survey
HALO is a major 23-acre redevelopment project in Kilmarnock. It comprises 13 acres of mixed used development, including domestic housing which will use a ground source heat array.
The EastHeat project installed solar panels and trial heat storage batteries in housing association properties across Edinburgh and the Lothian region. The EastHeat project will save its tenant up to 20% on the part of their fuel bill which provides hot water.
Stirling Renewable Heat project is a pioneering district heat network using heat extracted from wastewater, combined with biogas from sewage and combined heat and power (CHP) to heat a leisure centre, school, sports stadium and offices.
4D Heat is a new multi-partner project led by National Grid Electricity System Operator (ESO) and Scottish and Southern Electricity Networks (SSEN) which will explore the potential to use electric heat demand in off-gas areas of Scotland to soak up surplus wind generation, rather than reduce wind farms' output.
The 4D Heat project aims to find a way to match the flexible demand from electric heat to occasions when wind farms are generating too much power, without impacting on the distribution network.
