Methodology development for accounting of negative emissions via BECCS - case study CHP

Purpose and goal:

The project was created to strengthen Swedish energy companies´ opportunities to develop BECCS, by offering a method for demonstrating the net negative emissions of carbon dioxide produced by their planned facility. The project goal was to increase Swedish producers´ competitiveness to sell their negative emissions to external parties. The project has resulted in a tool now available and free to use.

In addition to providing an estimation of the amount of negative emissions, the tool can also be used to decide which parameters in the value chain have the greatest impact on the net. Expected results and effects:

The project resulted in the development of tools that can calculate the number of net tonnes that a BECCS system produces. results result is that the producers got an opportunity to understand their planned system better and thus be able to influence the design of the value chain to increase the climate benefits. results expected result is to contribute to the public discussion about how much climate benefit is created net by BECCS. At the company presentations that have been made, the tool and other documentation have given rise to many interesting follow-up questions and ideas.

Approach and implementation:

Conclusions from the implementation are that there was an unexpectedly large gap between how the research world and the cogeneration industry communicate and which words and concepts are used. Bridging the distance went well, but required a little more work than we expected.

Another conclusion is that each cogeneration plant is unique and that it is a challenge to make the balance between simplifying the tool and at the same time making it suitable for many different plants. Another conclusion is that there is potential to continue developing the tool to make it more user friendly.
