University of Houston’s Carbon Capture Breakthrough Cuts Costs, but Scale Remains Uncertain | Happy Eco News
The University of Houston’s carbon capture researchers achieved 90% CO2 removal at $70 per ton using membraneless technology; however, scaling faces challenges related to cost, policy, and infrastructure.

France Bets on Carbon Capture as North Sea Rivals Surge Ahead
France is accelerating carbon capture deployment, but structural weaknesses in transport, storage capacity, and political clarity threaten to slow its path to carbon neutrality.

Carbon Capture: Isolierte Atome ermöglichen grünes Methanol aus Wasserstoff - Golem.de
In Form von Methanol lässt sich Wasserstoff effizient speichern und kann direkt in Motoren verbrannt werden. Dafür muss er leicht verfügbar sein.

What happens if you offer generous subsidies💰 for Carbon Capture and Storage💨 - but you demand that projects deliver on time⏰?
In recent years, Denmark🇩🇰 has started a fast rollout of CCS technology. Unlike previous attempts, which were met with substantial resistance, this one happened without much opposition. A wide range of political parties supported the plans. 🧵

Denmark's CCS Strategy: Deliver or Pay
In recent years, Denmark pushed CCS technology and ran multiple tenders handing out substantial subsidies. But they came with a catch: either deliver on time or risk hefty penalties. What can be learned from the experiences in Denmark?

Study maps tree-planting risks and rewards for climate and biodiversity
Establishing forests can capture carbon and boost biodiversity — but some biomes are a better bet than others, a recent study finds. Forest restoration has emerged as a top nature-based solution to mitigate climate change, with numerous high-profile initiatives launched over the past few decades. And while there’s enthusiasm for replanting degraded forest areas, or […]

Kann sich das jemand anschauen und mir eine Zweitmeinung geben?
Bin mir nicht sicher, dass ich 1,5 Stunden Zeit für jemanden habe, der mit "I am picking up on a [problematic] vibe" ankommt und den dann nicht artikuliert.
Der als positives Beispiel für "generative AI"-Nutzung "materials used in carbon capture" (of all things) nennt.
Und dann ein "trust me, I am very good at this" einwirft, obwohl er bisher, wenn überhaupt, den gegenteili…

Jede bislang bekannte Carbon-Capture-Methode¹ ist teurer als den in Kohle, Öl und Gas gebundenen Kohlenstoff einfach im Boden zu lassen, statt ihn mittels Verbrennung in CO₂ zu verwandeln, und stattdessen Energie anderweitig herzustellen.
Klar, wir könnten Pflanzen wachsen lassen, und dann unter Luftabschluß sagen wir in alten Kohlebergwerken so einlagern, daß sie nicht gleich wieder vermodern, und wenn wir sie ganz ganz fest zusammendrücken, dann passen da auch genug rein, um genau da…

A sustainable photocatalytic pathway for concurrent hydrogen and value-added chemical production utilizing microalgae as bio-scavenger in water

Abstract: Microalgae are an abundant bioorganic material source and play a significant role in life on Earth by conducting photosynthesis for carbon dioxide (CO2) capture and its conversion to oxygen (O2). In this study, a combination of microalgae as a negative-CO2-emitting sacrificial agent with the traditional photocatalytic water-splitting process using brookite TiO2, as a model photocatalyst, is introduced as a new strategy to maximize green hydrogen (H2) production while converting microalgae to valuable products, like methane (CH4) and carbon monoxide (CO). The process, under optimal conditions, produces up to 0.990 mmol/g.h of H2 without cocatalyst addition and 3.200 mmol/g.h with platinum (Pt) cocatalyst, which is 13 times higher than the production rate without microalgae. The strategy of using microalgae in photocatalysis has high potential in green H2 production, as it not only eliminates valuable hole sacrificial agents, like alcohol, but also produces other useful compounds, like CH4 and CO. Moreover, this sustainable process contributes to CO2 capture and conversion during microalgae cultivation.

Governments across Canada should stop funding all these dubious carbon capture projects and just throw more Canadian Beavers at the problem. A good Beaver can solve anything.
