Ascent Project
5 - Safety and sustainability impact assessment

The main gaps in terms of safety for the different technology lines will be identified in this work package and recommendations will be outlined for the safe deployment and operation of these technology lines. Life Cycle Assessment (LCA) and Socio-Economic Assessment (SEA) of the investigated technologies are analysed in order to identify potential gaps that would be needed to facilitate the large scale implementation of these technology lines in the future.

The ASCENT consortium has now presented in the periodic general assembly held in Saragossa the methodology and interim LCA results for the different reference and ASCENT technologies studied.

The purpose (or function) of the different technologies studied is to produce electricity from fossil fuel (natural gas or coal) generating power, flue gas and water vapour. There are various processes and co-products involved, however, power production is the main goal of the different technologies studied. As a result, the chosen functional unit is to provide 1 kWh of electricity

The objectives of this interim report are as follows:

  • To calculate the environmental impacts over the life cycle of defined reference power plant technologies generating electricity from coal (IGCC) or natural gas (NGCC);
  • To calculate the environmental impacts over the life cycle of power plant technologies equipped with high-temperature technologies for pre-combustion CO2 separation and capture developed in the ASCENT project in order to identify the “hot spots”, key parameters and identify the main areas of environmental impacts;
  • To compare the ASCENT technologies with the conventional reference technologies, with or without carbon capture, and determine if the ASCENT technologies present an advantage in terms of environmental impacts or not.
