Cogeneration of Heat/Cool and Power from Gas (not exclusive to natural gas)
D - Electricity, gas, steam and air conditioning supply
Construction and operation of a facility used for cogeneration of heat/cooling and power from Gas Combustion (not exclusive to natural gas)
Climate Change Mitigation
Metric and threshold:
Any cogeneration technology can be included in the taxonomy if it can be demonstrated, using an ISO 14067 or a GHG Protocol Product Lifecycle Standard-compliant Product Carbon Footprint (PCF) assessment, that the life cycle impacts for producing 1 kWh of heat/cool and power are below the declining threshold. A full PCF shall be applied, using project specific data where relevant and shall be subjected to review. This assessment should include actual physical measurements, i.e. methane leakage measurements across gas extraction, transport and storage systems.
The Cogeneration Threshold is the combined heat/cool and power threshold of 100 gCO2e/kWh. This threshold will be reduced every 5 years in line with a net-zero CO2e in 2050 trajectory. Assets and activities must meet the threshold at the point in time when taxonomy approval is sought. For activities which go beyond 2050, it must be technically feasible to reach net-zero emissions. Facilities that will incorporate any form of abatement (e.g. CCS, Co-firing, other…) must show that the abatement activity is eligible under the Taxonomy. The full PCF assessment shall be subjected to review. Cogeneration from other fossil-fuel based gases would be eligible under the Taxonomy, subject to meeting the declining emissions threshold.
