TotalEnergies is targeting carbon neutrality by 2050 and to achieve that, must reduce its greenhouse gas (GHG) emissions. The E&P branch, which generates nearly half of the Group’s emissions, has set up a dedicated department to focus on Carbon Footprint Reduction (CFR). The team responsible for CFR in E&P has developed a roadmap to reduce the emissions of the branch’s operated assets from 18 million metric tons of CO2 in 2019 to 16.2 million in 2025. Emmanuel Pradié, who leads the CFR department talks about these challenges.

Digital technology, a strategic approach

One of the concrete actions being taken by E&P affiliates to reduce GHG emissions is displaying and monitoring these emissions on sites in real time.

Real-time display and monitoring of GHG emissions

This project is intended to provide our operated assets with digital displays to monitor their calculated or estimated GHG emissions and energy efficiency indicators in real time. These tools support operational decision-making (on site and/or at base) whilst taking environmental constraints into account.

There are three levels of challenges. Firstly, we need to adopt a timescale that is in phase with decision-making. Real-time monitoring will supplement the monitoring of safety processes and systems already in place in control rooms and smart rooms. The impact of any action decided on site (stopping/starting a machine, changing a process parameter, etc.) can therefore be assessed using these new indicators with a view to reducing our emissions and improving our energy performance.

Next, we must be able to gauge actions to optimize design and reduce GHG emissions through other projects in the CFR roadmap in order to identify the most relevant and effective. Lastly, our affiliates and assets all need to be put on an equal footing, digitally-speaking, so we must provide a simple solution based on a suite of software (Plant Information or PI) that is already available and in use.

A high value-add initiative

Besides this initiative making it possible to provide all our affiliates with a simple solution to monitor greenhouse gas emissions, it will also - for the first time - enable us to assess the individual emissions of some GHG-emitting equipment. For example, we can estimate the GHG emissions of one gas turbine and compare it to another. This solution, coupled with the monitoring solutions already in place for this equipment, would enable engineers to optimize the operating parameters of the equipment and thus move towards reducing emissions.

Lastly, the initiative is based on a suite of software that enables the creation of standardized or “template” solutions: calculations and displays only need to be authored once, at the start of the project, and can then be deployed rapidly for the maximum number of assets in different affiliates, maximizing the ratio of asset numbers to time invested. As this suite of software is already in use in all our operating affiliates, investment, deployment and maintenance effort will also be minimized.

An initial pilot in Angola

An initial release (enabling the monitoring of emissions generated by rotating machines) has been presented to TotalEnergies’s Angola operations and  covers all the assets in blocks 17 and 32. Identical work has been carried out on the deepwater assets in Nigeria and is being rolled out in other affiliates, starting with those with the highest emissions (Nigeria, Congo, etc.). A second release (incorporating flare emission and energy efficiency calculations) is already being deployed in the same deepwater operations and the Project team is considering developing new real-time views and additional indicators for 2021. In parallel, the test phases of these releases will give us feedback enabling us to correct and improve the solution and ensure its adoption by the operating teams. In all cases, the initiative and solution are being developed in collaboration with existing digital initiatives (Digital Asset Flagship in our UK operations, Digital Factory use cases for our Angola and Nigeria operations, etc.).
