Project: 101084405 - CRONUS - HORIZON -CL5-2021-D3-03

Research on Sustainability Transitions

The overall approach is built on insights from research on ‘sustainability transitions’ that analyses innovation within socio-technical systems.

13 partners from 8 countries

The project will be delivered by 13 participant organisations representing 8 European countries

CRONUS addresses the current gaps in biofuels production, namely the carbon waste and biogenic effluent gases

The overall objective of CRONUS is to develop, assess and test 5 new integrated and sustainable technological solutions for highly efficient biogenic effluent gases CUS within the biofuels value chain.

  • enzymatic capture of CO2
  • autotrophic algae cultivation
  • biological CO2 hydrogenation
  • syngas biomethanation
  • biogenic carbon storage through biochar production
  • in-situ biomethanation using Microbial Electrolysis Cells

5 Functional Prototypes will be designed, constructed and tested

In order to achieve a strategic capture, utilization and storage of biogenic effluent gases within biofuels production lines, integrated processes will be up-scaled according to the optimized scenarios derived during lab scale investigation. In this context, 5 Functional Prototypes will be designed, constructed and tested in a relevant environment.

New Peer-Reviewed Publication: Advancing Potassium Carbonate–Based CO₂ Capture

We are pleased to announce the publication of a new peer-reviewed study demonstrating the technical feasibility of potassium carbonate–based CO₂ capture as a robust alternative to conventional amine systems. Using detailed rate-based process modelling, the study achieves approximately 90% CO₂ removal across representative industrial flue gas streams, including cement production, biomass combustion, and biogas upgrading.

Crude Microalgae Extract for Increased CO2 Capture and Higher Biomass Production in Algal Cultivation Systems

Authors: Maja Berden-Zrimec, Domen Lazar, Domen Trontelj, Elli Maria Barampouti, Sofia Mai, Dimitrios Malamis, Robert Reinhardt This study demonstrates that crude microalgal extracts containing carbonic anhydrase (CA) can enhance inorganic carbon utilization in algal cultivation. CA-containing extracts prepared from Scenedesmus-dominated biomass were shown to increase specific growth rates of Chlorella sorokiniana by 21–82% in digestate-based […]

Methodology

CRONUS will deliver a unique platform of novel technologies, suitable for easy integration to the existing biofuels production plants, able to upcycle dissimilar kinds of biogenic effluent gases to biofuels ready to be distributed within installed grids and biochar, as biogenic carbon sink.
