The first terawatt of solar was the hardest.

True story. It was great to return to #negativeco2conference, now w @JoePerryman1, and meet with @RobertHoglund & @coreyamyers again - without whom @Brineworks would not exist. Stay tuned!

[Robert Höglund @RobertHoglund]

Two years ago I dragged along @Guffi to this talk by @coreyamyers, and he got so excited he started @Brineworks
A full fledged Direct ocean capture company with offices in Amsterdam and really promising results!

A massive AI CDR Heart to keep track of all the research

Only one person in the world probably scans through the majority of CDR publications, and that's Andrew Lockley @geoengineering1. For the rest of us, we have to pick and choose, with only specialists in specific CDR methods able to follow all the research developments. Today, there are over 50,000 publications on CDR, with most research coming from China, driven by studies on biochar and soil carbon sequestration interestingly enough.

There is a solution: the State of CDR team has built a living, AI-enhanced systematic map of CDR research that tracks developments in the field almost in real-time.

The interactive tool, hosted on the State of CDR Data Portal, lets users identify relevant research through pre-defined filters.

Very cool

@salkagullbra @jokull Sorry, það var ekki beint meiningin. Og var nuna að læra þetta geggjaða hugtak. Ekki hjalpleg = meina að eg held þetta tvit hjalpi ekki almennt við að rallya þvi folki sem þu vilt rallya ❤️

@jokull @salkagullbra Sammala @jokull. Rikisstjorn KJ, og su nuverandi hefur brugðist. Það er ekki einungis KJ að kenna. Hun hefði getað slitið samstarfi utaf þessu en þa hefðum við setið uppi með nyja rikisstjorn sem hefði liklegast verið enn verri. Held þessi orðræða se ekki hjalpleg @salkagullbra.

@AndreasenJack Or are based on some very optimistic $/MWh estimates.

Yesterday a new study was shared that estimated the cost of DACCS won’t go below $340/t. But at the same time DACCS costs from some companies are already close to, or at this level.

In this post, I show that the cost of DACCS is lower in the near term than people are assuming.

Today, we're dropping the second-annual https://t.co/5DYVuAVbgw Year in Review: an in-depth look into key trends in the durable carbon removal market

Some key trends:
🚀 CDR purchases grew 7.3x to 4.5 megatonnes (Mt), up from 0.615 Mt in 2022,
🚚 Deliveries grew 2x from 2022 to 2023, up to 125kt
🌿 Biochar represented 94% of CDR deliveries

@hajak @michael_nielsen Laugavegur is nice but for 5-7 days in Iceland I’d recommend Hornstrandir or Lónsöræfi!

During #ClimateWeekNYC, global leaders convene to discuss vital climate action. Imagine a world where those flights don't add more emissions. Enter EP-1, our pioneering all-electric propulsion system prototype—a leap toward that reality. Learn more at https://t.co/Da3AUAPTYw
