Washington Post: Carbon Removal Is Where Green Investment Should Go

by Lara Williams (Bloomberg) on washingtonpost.com, January 27, 2023 at 10:49

„Green investment hit a milestone in 2022: The world put as much money into replacing fossil fuels as it put into producing them, with clean energy investments jumping 31% from 2021 to top $1 trillion for the first time. Of course, it’s not job done. Annual investments into decarbonizing the economy must triple for the rest of this decade. One area that’s seen a dramatic expansion in investment lately is carbon capture.“

Japan sets carbon capture roadmap with 6-12 million tonne/year target by 2030

on channelnewsasia.com; 26 Jan 2023 09:47PM

„TOKYO : Japan’s industry ministry on Thursday set a target of annual carbon dioxide (CO2) storage capacity of 6-12 million tonnes by 2030 under a long-term roadmap for carbon capture and storage (CCS). Japan sees CCS technology – which removes CO2 emissions from the atmosphere and stores them underground, and which a host of Japanese companies said on Thursday they were working on – as essential to achieving its goal of carbon neutrality by 2050.“

Phys.org – What Is Blue Carbon and How Can It Help Fight Climate Change?

by Olga Rukovets on Phys.org, 26 January

„According to the National Ocean Service, „blue carbon is simply the term for carbon captured by the world’s ocean and coastal ecosystems.“ So why is it important? And what role can it play in addressing climate change?“ Researchers at Columbia Climate School discuss the benefits and challenges of working with carbon from ocean and coastal ecosystems.

Re-carbonizing the sea: Scientists to start testing a big ocean carbon idea

by Jeremy Hance, on mongabay.com, 25 January 2023

„Ocean alkalinity enhancement (OAE) involves releasing certain minerals into the ocean, sparking a chemical reaction that enables the seawater to trap more CO₂ from the air and mitigating, albeit temporarily, ocean acidification. Some scientists believe OAE could be a vital tool for drawing down and securely storing some of the excess CO₂ humanity has added to the atmosphere that is now fueling climate change. Yet many questions about OAE remain, including most prominently how it would impact marine life and ecosystems. Several programs are aiming to spark the research needed to answer these questions, including field tests in the ocean.“

Nature – Carbon capture nets 2 billion tonnes of CO2 each year — but it’s not enough

Miryam Naddaf, on Nature.com, 23 January 2023

„As well as cutting emissions, governments need to ramp up investment in carbon dioxide removal technologies to hit climate goals, researchers warn. (…) The report, called The State of Carbon Dioxide Removal, provides the first global estimates of the total amount of carbon that is being sucked out of the air each year, and predicts how much this will have to increase under various emissions scenarios.“

A Solution to Excess CO2? New Study Proposes Fertilizing the Ocean

by Beth Mundy on scitechdaily.com, January 20, 2023

„An international team of researchers led by Michael Hochella of the Pacific Northwest National Laboratory suggests that utilizing tiny organisms could be a solution to addressing the pressing need to remove excess carbon dioxide from the Earth’s environment. The team conducted an analysis, published in the journal Nature Nanotechnology, on the possibility of seeding the oceans with iron-rich engineered fertilizer particles near ocean plankton, crucial microscopic plants in the ocean ecosystem, to boost the growth and carbon dioxide uptake of phytoplankton.“

Revealed: more than 90% of rainforest carbon offsets by biggest provider are worthless, analysis shows

Patrick Greenfield, The Guardian, 18 Jan 2023 14.00

The research into Verra, the world’s leading carbon standard for the rapidly growing $2bn (£1.6bn) voluntary offsets market, has found that, based on analysis of a significant percentage of the projects, more than 90% of their rainforest offset credits – among the most commonly used by companies – are likely to be “phantom credits” and do not represent genuine carbon reductions.
