Using alkaline rock minerals to combat climate change

Press release on geomar.de

How can carbon dioxide (CO2) be removed from the atmosphere and stored safely and permanently in the ocean? This question is being investigated by scientists from seven nations led by GEOMAR Helmholtz Centre for Ocean Research Kiel in an experiment just starting in the Raunefjord near Bergen, Norway. In mesocosms, free-floating, experimental enclosures, they are exploring whether the ocean can absorb additional CO2 from the atmosphere through the addition of alkaline minerals – known as ocean alkalinisation – and what influence this has on marine communities. The study will last until mid-July and takes place as part of the Ocean-based Negative Emission Technologies (OceanNETs) project funded by the European Union.

Bloomberg: Is Carbon Removal Finally Getting Serious?

Bloomberg opinion editorial

„In a field long plagued by hype and high costs, new startups are showing real promise. The question is whether they can scale up in time. […] Philanthropists and government agencies have long offered prizes for various carbon-removal benchmarks. And inchoate efforts are underway to turn stored carbon dioxide into something economically useful. Yet none of these efforts amounts to a sustainable business. […] In time, companies may devise cleverer ways to commercialize removed carbon, rendering advance commitments moot. Perhaps the $12 billion Congress pledged to the technology in last year’s infrastructure bill will lead to a breakthrough. Maybe green-energy investment will yield much faster emissions reductions than expected. But for now, an all-of-the-above approach makes sense — and harnessing the magic of competition can only help.“


Voters Want State and Federal Lawmakers to Lead on Carbon Dioxide Removal

by Celina Scott-Buechler and Toby Bryce on dataforprogress.org

„The New York Carbon Dioxide Removal Leadership Act (CDRLA) marks the first of its kind: a state-level bill aimed at advancing CDR deployment in the immediate term to ensure it’s ready to be scaled up when we most need it and done so in a sustainable and progressive way. The act authorizes the creation of a state-run advance market commitment for durable carbon removal, starting with a very small amount (10,000 tons in 2024) that doubles each year through 2029.[…] And the New York CDRLA is popular: recent Data for Progress polling in New York state finds that 72 percent of voters approve of the state legislature passing a bill to accelerate the development of carbon removal approaches and technologies. This includes 85 percent of Democrats, 66 percent of Independents, and 57 percent of Republicans.“


CNN: DOE announces multibillion-dollar project to kickstart a carbon dioxide removal industry in US

by Ella Nilsen, CNN May 19, 2022

The US Department of Energy is announcing a massive investment in direct air carbon removal projects, in hopes of kickstarting an industry. On Thursday the DOE relesead a notice of intent for developers for four direct air capture hubs – each capable of removing over a million tons of CO2 per year — using $3.5 billion from the bipartisan infrastructure law.


Greenhouse gas removal: How could it help the UK reach net-zero by 2050?

on carbonbrief.org

A mix of scientists, economists and government advisers met in London last week to discuss how removing greenhouse gases from air could help the UK hit net-zero emissions by 2050. Over two days, researchers and policy experts debated the scalability of CDR techniques, as well as the potential benefits and drawbacks for UK communities and the country’s ailing wildlife. Carbon Brief was there to take in the scientific presentations, panel discussions and lunchtime chatter and has produced an in-depth summary of the event.


The Hill: The climate solution that can also restore our seas

by Brent Fewell and Alex Carlin, opinion contributors – 05/10/22

The National Academies of Sciences released a report assessing potential benefits of ocean-based carbon dioxide removal strategies and calling for more research to learn how these methods could help mitigate the impacts of climate change. Among the strategies recommended is ocean iron seeding or ocean pasture restoration (OPR) – what is discussed in this article.


Investment in Carbon Removal Technologies Just Hit an Inflection Point

„At Columbia Business School’s 2022 Climate Business & Investment Conference, hosted by the Tamer Center for Social Enterprise and Columbia Climate School, some of the leading investors in the space—as well as a representative from one of the companies developing this technology—gathered for a panel discussion about the possibilities and limitations of carbon capture technologies and the auspicious moment in which they currently find themselves.“
