Explained: what does 'unabated coal' mean? E3G

Jun 24, 2021 Reducing emissions from ‘unabated coal’ power generation. In the case of coal power generation, abatement is generally understood to mean the use of Carbon Capture and Storage (CCS), or Carbon Capture, Utilisation and Storage (CCUS) technology. So in converse, ‘unabated coal’ means coal power plant without CC (U)S technology equipment.

Tackling emissions World Coal Association

As with other forms of thermal power generation, water in coal-fired plants is used in different ways depending on the type of cooling technology employed. Many technologies do not consume significant amounts of water, but it is important to make sure that the extraction and return process minimises impacts on water temperature and wildlife.
