With this event the culmination of the third year of the Carbon to Value (C2V) Initiative will be celebrated! Hear from the 8 Year 3 Cohort startups shaping the future of the carbontech industry as they each present their solutions, the progress they’ve made throughout the past six months of the C2V program, and where they are headed next.

In seven years, CO2 removal (CDR) technologies are expected to reach a Technology Readiness Level (TRL), relevant to industrial applications. The most promising technologies are at TRL-7, but the jump to TRL-11 in the new IEA scale for disruptive technologies looks unlikely because the scale-up from small pilots to industrial scale requires time and large investments. Moreover, validation on a large scale is still missing or even unplanned. This work also identifies the critical materials supply chain and the competition with the energy transition as limiting factors which could further hinder DAC deployment and reduce DAC contribution in the next years when a first significant emissions cut should be addressed.

Direct air capture (DAC) technologies require high regeneration energy to release CO2 from sorbents. Various approaches have been tested and optimized for different DAC systems. This review demonstrates that the work equivalent regeneration energy demand (supported by either the electric grid or fossil fuel combustion) ranges from 0.5–18.75 GJ/t-CO2 for solid sorbent DAC systems and 0.62–17.28 GJ/t-CO2 for liquid solvent DAC systems.

This review presents a comprehensive survey of recent advancements, challenges, and potential applications of DAC technology, with an emphasis on the recent rapid increase in the number of DAC developers, the majority of them being founded in the past 4 years.

„Pflanzenkohle hat im Kampf gegen den Klimawandel großes Potenzial – insbesondere in der Landwirtschaft. Dr. Maria-Elena Vorrath aus dem Fachbereich Erdsystemwissenschaften der Universität Hamburg will ein neues Herstellungsverfahren entwickeln und testen. Dafür erhält sie aus dem „Klaus Tschira Booster Fund“ für die kommenden zwei Jahre 80.000 Euro.“
CDR.fyi is the largest open data platform dedicated to high-permanence CDR monitoring. Their goal is to equip market participants, policymakers, consultants, academic researchers, and capital allocators with up-to-date, accurate data on the CDR industry to guide investment and help scale this important component of the climate equation.

This paper proposes and tests a photovoltaic-powered DAC (Direct Air Capture) system in a generic residential building located in Qatar. It can efficiently reduce CO2 concentration in a living space, thus providing an incentive to individuals to adopt it. The ventilation performance of the building is determined using Computational Fluid Dynamics (CFD) simulations, undertaken with ANSYS-CFD. The CFD model was validated using microclimate-air quality dataloggers.

„The U.S. Department of Energy (DOE) today announced 16 projects across 14 states are set to receive $23.4 million to provide locally-tailored technical assistance and enhanced stakeholder engagement around carbon management technologies. The projects, housed at both universities and private sector companies, aim to connect carbon management developers with local communities to foster collaboration and education toward the advancement of commercial deployment of carbon capture, transport, and storage technologies across the United States. Large-scale deployment of carbon management technologies will help reduce emissions from hard to decarbonize industrial facilities and power plants, which is crucial to meeting President Biden’s ambitious climate goals.“

Here the authors demonstrate a continuous electrochemical carbon-capture design by coupling oxygen/water (O2/H2O) redox couple with a modular solid-electrolyte reactor. By performing oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) redox electrolysis, their device can efficiently absorb dilute carbon dioxide (CO2) molecules at the high-alkaline cathode–membrane interface to form carbonate ions, followed by a neutralization process through the proton flux from the anode to continuously output a high-purity (>99%) CO2 stream from the middle solid-electrolyte layer. No chemical inputs were needed nor side products generated during the whole carbon absorption/release process.

The authors analyzed scenarios that include direct air capture of CO2 with storage (DACCS), a novel CDR technology that is not dependent on land potential and can be deployed widely, as well as regional variations in institutional capacity for mitigation based on country-level governance indicators. They find that including novel CDR and representations of institutional capacity can enhance both the feasibility and fairness of 2 °C and 1.5 °C high-overshoot scenarios, especially in the near term, with institutional capacity playing a stronger role than the presence of additional carbon removal methods.
