A New Species Emerges: Applied Biomimicry
How do things come to life? How do new species emerge from coincidences? Those questions (…)
A cooperation project between Arne Knöchel, Stefan Max Garzarolli and COBIOM
If global warming is to be limited to 1.5 degrees, CO2 will likely have to be removed from the atmosphere to offset unavoidable emissions from agriculture and industry. This is shown in the special report published in 2018 by the IPCC. The European Commission also expects that “negative emissions” will be necessary for the declared goal of a greenhouse gas-neutral Europe by 2050. Various ways of removing CO2 from the atmosphere should, therefore be investigated – including bioenergy with carbon dioxide capture and storage (BECCS). *(1)
The term bioenergy with carbon capture and storage (BECCS) describes a process of CO2 separation and storage, in which biomass is burned in industrial processes, in order to subsequently remove the resulting carbon dioxide to deposit and save. In the context of the climate crisis, BECCS is seen as a theoretically promising procedure, the application of which should contribute to achieving the two-degree target from the Paris Agreement. * (2)
Chemical looping combustion (CLC) is an innovative concept that offers a potentially attractive option to capture CO2 with appreciably lower thermal efficiency penalties when compared to the traditional approaches. *(3)
In contrast to traditional approaches, CLC represents a cheaper and more effective method of CO2 separation. With this technology, it is possible to reduce the cost per captured ton of CO2 from currently 80-100 Euro to an estimated 30-40 Euro. *(4)
This project deals with the realisation of a technical and methodical prototype for testing and optimising the economic efficiency of CLC-based BECCS.
This prototype will be realised by using bark beetle-damaged dead wood from Thuringian forests and an existing decommissioned 32 MW CLC plant called GobiGas in Gothenburg. In the future, the CO2 will be stored in reservoirs such as Porthos, Northern Lights, Aberdeen, Drax and Northgate et. al. In this way, proof of the economic efficiency and scalability of this technology could be provided in a short period of time typical for this kind of project.
Realisation period 1.5 – 2.5 years
The investment costs for the realisation of this project amount to approx. 10 – 15 million Euro depending on the recommissioning costs of the CLC plant and the costs for CO2 storage.
