The Boltzmann Institute's project What We'll See Down Two Pathways compared two pathways to net-zero heating for buildings in Canada.
The pathways considered, which would, by 2050, replace (almost) all at-building heating equipment that burns fossil fuels (primarily natural gas) with a zero-emissions heating alternative, are:
- Electrification Pathway - Use electrically powered heat pumps (primarily air-source, but also ground-source where feasible) installed at individual buildings. In very cold weather when heat pumps lack adequate capacity, use electric resistance elements for supplementary heat. The electricity supply would need to have net-zero emissions.
- Thermal Networks Pathway - Supply heat to buildings using thermal network utilities, also known as district heating or district energy. The sources of heat would need to have net-zero emissions.
To support the mandate of Canada’s Net-Zero Advisory Body related to research, this project was undertaken with the financial support of the Government of Canada. Funding was provided through the Environmental Damages Fund’s Climate Action and Awareness Fund, administered by Environment and Climate Change Canada.
