Résumé
Industrial electrification is an important step on achieving net-zero in industry. For several industrial subsectors in Canada, a significant portion of the energy input is consumed in fossil fuel boilers. An interesting solution is the replacement of the boiler with a high temperature heat pump (HTHP) capable of delivering the required process heat. The efficiency of a HTHP being closely dependent on the waste heat temperature levels, this effect is also studied. The results show that electrification of boilers by HTHPs being supplied with waste heat at 29°C leads to energy savings of 11%, 14% and 38% in the petroleum refining, pulp and paper and food and beverage subsectors respectively. These numbers can significantly increase when part of the heat can be obtained through heat recovery alone and/or heat pumping from higher-temperature waste heat, which is expected to always be the case, although in proportions that are site-specific. One challenge in making HTHP projects cost-effective is the higher electricity cost compared to fossil fuels. This issue is partly addressed through carbon pricing mechanisms and a high coefficient of performance (COP).
