Climate Transformed host Karolin Schaps interviews Howard Gunstock, Chief Kelper and Co-Founder of Carbon Kapture, a company that grows seaweed with the aim of removing CO2 from our oceans and atmosphere.
Climate discourse with Kate McKenzie (at Applepodcast)
Kate was joined by Wil Burns for a special edition of the Climate Discourse podcast to discuss the fascinating science and legal complexities of carbon removal law. They were joined by Romany Web to talk about a series of papers she published on the law of enhanced weathering for carbon dioxide removal. This is the first episode in a series highlighting some of the most important research in this area. (40 min in total)

Within the special Research Topic of Frontiers about Ocean Artificial Upwelling: In this study, the effect of different intensities of artificial upwelling was investigated combined with two upwelling modes (recurring additions vs. one singular addition) on POC export, sinking matter stoichiometry and remineralization depth.

A novel coupling of HVAC-systems (heating, ventilation and air conditioning systems) with DAC-technology (direct air capturing technology) is proposed to separate CO2 in the exhaust air of buildings and recirculate the CO2-depleted air back into the building.

Brussels, Dec 1: The European Union plans to capture five million tonnes of carbon dioxide from the atmosphere each year by 2030 through technologies, and create an EU system to certify carbon removals.
Climate Vault, an award-winning non-profit founded at the University of Chicago, today issued an RFP (Request For Proposal) to identify, assess, and award funds to Carbon Dioxide Removal (CDR) technologies that are helping make net negative emissions possible. Climate Vault will award successful CDR applicants funding for an equivalent mass of carbon removed with the value of the award being based on the market price of Climate Vault’s held carbon permits.
Since November 24 , „Carbon Removal“ – a Norwegian development company, „Carbon Engineering (CE)“ – a leading provider of Direct Air Capture (DAC) technology that captures carbon dioxide (CO2) out of the atmosphere, and „Oxy Low Carbon Ventures (OLCV)“ – which is developing large-scale DACs for use in CO2 storage projects, announced they are working together to deploy commercial DAC projects in Norway.

While land-based solutions, especially forests, have received a lot of attention in the past, this is not the case for ocean-based solutions. Thus in this working paper of the Kiel Institute of Economy, the focus is on different blue carbon ecosystems (BCEs), their potential for sequestering and storing carbon, and the management challenges they involve.

Model-based scenarios are used to inform policymakers about emissions pathways and cost-effective carbon prices. Many of these scenarios are based on the Hotelling rule, assuming that a carbon price path increasing with the interest rate leads to a cost-effective strategy. The robustness of this rule was tested by using experiments with plausible assumptions for learning by doing, inertia in reducing emissions, and restrictions on net-negative emissions.
