Waste heat is the most sustainable potential source of heat and deserves special attention at assessing energy mix of sustainable and energy efficient district heating system. However, obtaining data from industries can be very challenging
Mapping the waste heat sources
Instructions for the mapping of waste heat potentials were developed within the Interreg CE project CE-HEAT (see Instructions for a waste heat cadastre creation based on CE-HEAT cadastre development process – available under Waste_Heat_Cadastre_Development_Guide.pdf). The application of the methodology described there - as summarised below is still recommended - Read more
The guide serves as a practical manual for organizations developing waste heat or broader energy cadastres with the following main objectives:
- Facilitate the matching of waste heat supply with energy demand.
- Support investors in identifying opportunities for heat recovery networks.
- Raise awareness among policymakers and the public about the potential of waste heat.
Waste heat mapping is intended to achieve the following key results:
- Improved visibility of waste heat potential.
- Enhanced cooperation between industry, government, and energy planners.
- Contribution to regional energy efficiency and sustainability strategies.
To reach established stakeholders across the energy and environmental sectors, waste heat cadastres should be integrated into existing regional or national energy cadastres. The aim should be to combine energy data into one accessible system for analysis and planning purposes. Therefore, interoperability for GIS data processing is essential. To ensure data sharing and compatibility between regional and national cadastres, the guide recommends using a uniform data export structure with two tables in CSV, Excel or JSON format.
Waste heat data collection
The data required for estimating and mapping waste heat potentials can be obtained directly from companies or calculated based on emission data. The collection of the following essential data is recommended in connection with waste heat:
- Key data about the company (company name, website, contact person if applicable, industrial sector - using NACE codes, …)
- Total available waste heat (MWh/year) from all plant sources
- Medium type (air, liquid, solid)
- Temperature (°C)
Assessing the regional waste heat potential
Assessing the waste heat availability at regional or national level is also very useful for energy planning and can be done at macro level without knowing the specific data from industry. The only data required for the estimation are the official energy statistics for industry sectors of the region of interest and specified conversion factors.
