Twence has plans to capture CO2 on a large scale from its Energy from Waste plant and make it available for useful application. This means this CO2 will no longer be emitted directly, and that is good for the environment. In September the Memorandum on Scope and Detailing, the former ‘notification of intent’ for the environmental impact assessment, was submitted to the Province. In the coming months, the Province will evaluate which questions about environmental effects need to be investigated and answered so that Twence can be awarded an integrated environmental permit for this project (the Guidelines).
For activities that can have major environmental effects, it is obligatory to perform an environmental effects investigation and make an environmental impact assessment (EIA). Twence has asked engineering consultancy firm Witteveen en Bos to work out the EIA for this project. The guidelines for the EIA are expected to be laid down by the competent authorities in December of this year. Witteveen en Bos has already started a number of (partial) investigations in anticipation of these guidelines. The intention is to submit the EIA in January 2018.
Capturing and reusing CO2 is of huge importance to stop further global warming. Twence can contribute to this. The aim is to capture 100 ktonne CO2 per year as well as find good uses for it. The scale corresponds roughly with the impact of more than 30 wind turbines in CO2 equivalents.
After the carbon dioxide gas is isolated from the flue gases, it is liquefied for transport to the customers. There are various possibilities for the useful application of CO2, for instance as ‘fertiliser’ in glasshouse horticulture and as a basic substance in the production of fuels, raw materials and construction materials.
Our experience in capturing CO2 has been growing since 2014. With our ‘own’ CO2 we produce sodium bicarbonate, which we then use to scrub flue gases. This is on a relatively small scale, for our own use. The knowledge this has given us is highly valuable for ourselves, but also for others. It is attracting interest from all over Europe.
In Europe the primary aim of many existing plants and new plants under development is to capture CO2. Twence takes an important step further in its development as a raw material company by also focusing on the next step: ‘useful application.’
