Installation

First you need to setup your conda environment.

conda env create -f environment.yml

You can also use any management of environment you want the installed libraries are standard: matplotlib, numpy, pandas.

The only special library is gboml. You can find the documentation and installation guide here: https://gboml.readthedocs.io/en/latest/

How to use the code

In order to reproduce the results obtained in the article run:

python3 main.py -sc $num_scenario -y 2

There are 5 scenarios from 1 to 5.

Therefore, $num_scenario \in {1, 2, 3, 4, 5}

This framework allows a valorization of CO2 using carbon capture technologies. This valorization is grounded on the idea that CO2 gathered from the atmosphere or post combustion can be combined with hydrogen to produce synthetic methane. The hydrogen is obtained from water electrolysis using renewable energy (RE). Such renewable energy is generated in RREHs, which are locations where RE is cheap and abundant (e.g., solar PV in the Sahara Desert, or wind in Greenland). We instantiate our framework on a case study focusing on Belgium and 2 RREHs, and we conduct a techno-economic analysis. This analysis highlights the key role played by the cost of the two main carbon capture technologies: Post Combustion Carbon Capture (PCCC) and Direct Air Capture (DAC). In addition, we use our framework to derive a carbon price threshold above which carbon capture technologies may start playing a pivotal role in the decarbonation process of our industries. For example, this price threshold may give relevant information for calibrating the EU Emission Trading System so as to trigger the emergence of the multi-RREH.} }
