Australia and Japan Are Quietly Building a DAC and Hydrogen Partnership

Australia and Japan Are Quietly Building a DAC and Hydrogen Partnership

While America’s $3.5 billion DAC hub program sits in bureaucratic limbo, Australia’s climate minister Madeleine King was in Kobe meeting with Kawasaki Heavy Industries executives about direct air capture and hydrogen. No audits. No 500-day review. Just two countries making plans. Why KHI matters#Kawasaki Heavy Industries isn’t a climate startup hoping to survive its next funding round. It’s a $15B+ industrial conglomerate that builds gas turbines, LNG carriers, ships, aerospace components, and rolling stock. When KHI shows up at a DAC meeting, it means heavy industry — the kind that actually builds infrastructure at scale — sees a business case. ...

Biochar Just Got Another Job: Destroying Antibiotics in Water

Biochar Just Got Another Job: Destroying Antibiotics in Water

A biochar composite laced with carbon nanotubes and iron carbide (Fe₃C) removes over 90% of common antibiotics from wastewater within hours. That’s 15 times better than conventional treatment materials. Every time biochar proves useful for something beyond carbon removal, the CDR business case gets stronger. This one’s a big deal. The problem it solves#Antibiotics like enrofloxacin and amoxicillin are everywhere in wastewater — from hospitals, farms, and households. Conventional water treatment doesn’t remove them well. They persist in the environment, driving antibiotic resistance, which the WHO calls one of the top ten global health threats. We need better tools. ...

The Math on DAC Subsidies: $900B to $3T, and It's Worth It (With a Giant Asterisk)

The Math on DAC Subsidies: $900B to $3T, and It's Worth It (With a Giant Asterisk)

Subsidies for direct air capture must exceed $200–330 per ton of CO2 and be sustained for decades. That’s not an activist estimate — it’s the central finding of the first rigorous uncertainty analysis of DACCS scaling, published by researchers at Politecnico di Milano and ETH Zurich. The total public bill? Between $900 billion and $3 trillion. Before you close this tab: the investment pays back by mid-century. But only if — and this “if” is load-bearing — we simultaneously cut emissions hard. ...

CDR Daily Digest — March 20, 2026

Five original posts today — anchored by a Princeton study that challenges one of CDR’s most relied-upon pathways, and bookended by a fashion-industry-first DAC deal and new soil science that matters for enhanced weathering. ⚠️ BECCS May Emit More Than Natural Gas for Decades#BECCS May Emit More Than Natural Gas for Decades, Princeton Study Finds A preprint from Princeton, Hong Kong University, and WRI drops a bomb on bioenergy with carbon capture and storage. Their analysis: when you account for land-use change, supply chain emissions, and the decades-long carbon payback period of growing new biomass, BECCS could produce higher net emissions than just burning natural gas — for decades. That’s a problem, because BECCS underpins a large share of IPCC scenarios that keep warming below 2°C. The paper doesn’t say BECCS can never work, but it argues that the conditions under which it delivers net-negative emissions are far narrower than most models assume. ...

How Organic Carbon Changes Enhanced Weathering Reactivity

How Organic Carbon Changes Enhanced Weathering Reactivity

Enhanced weathering sounds simple in theory: spread crushed rock on farmland, let it dissolve in soil water, and the chemical reactions pull CO₂ out of the atmosphere. In practice, the soil has opinions. New research presented at EGU 2026 — the European Geosciences Union General Assembly in Vienna — digs into one of the field’s most important open questions: what happens when you combine enhanced weathering with organic carbon amendments? The answer appears to be “it depends” — which in soil science means “it’s complicated.” ...

Chinese Startup Claims Competitive Synthetic Fuel From Air and Water

Chinese Startup Claims Competitive Synthetic Fuel From Air and Water

A Shanghai-based startup called Carbonology claims it has cracked the economics of synthetic fuel production — making petrol, diesel, jet fuel, and naphtha from atmospheric CO₂ and water at prices competitive with fossil fuels. If true, it would be one of the most significant breakthroughs in the history of carbon utilization. If not, it joins a long list of overblown e-fuel announcements. The details so far lean heavily toward the “if” side. ...

Coach and Kate Spade's Parent Signs 10-Year Carbon Removal Deal With Climeworks

Coach and Kate Spade's Parent Signs 10-Year Carbon Removal Deal With Climeworks

While US corporations are quietly retreating from climate commitments under political pressure, one major fashion group just went the other direction. Tapestry — the parent company of Coach, Kate Spade, and Stuart Weitzman — has signed a 10-year carbon removal partnership with Climeworks, the Swiss direct air capture company. It’s the first deal of its kind from a North American fashion company, and the length of the commitment stands out: a decade is an eternity in corporate sustainability, where most buyers sign one-year or three-year purchase agreements. ...

CDR Misconception #2: DAC Uses Too Much Energy to Ever Work at Scale

CDR Misconception #2: DAC Uses Too Much Energy to Ever Work at Scale

The Myth#“Direct air capture consumes insane amounts of energy. It’ll never work at scale — we’d need entire power grids just for DAC.” This is probably the most common objection to DAC. And unlike last week’s misconception, there’s a kernel of truth here. DAC is energy-intensive. But the conclusion — that it can never scale — doesn’t follow. Here’s why. The Energy Numbers (Real Ones)#Current DAC systems use roughly 2,000–3,000 kWh of combined thermal and electrical energy per ton of CO₂ captured. That’s a lot. For context, it’s about what two American households use in a year. ...

BECCS May Emit More Than Natural Gas for Decades, Princeton Study Finds

BECCS May Emit More Than Natural Gas for Decades, Princeton Study Finds

Bioenergy with carbon capture and storage — BECCS — is the IPCC’s workhorse. It appears in the vast majority of net-zero pathways. Climate models lean on it to close the gap between what emissions reductions can achieve and what the atmosphere actually needs. It’s supposed to be the technology that makes the math work. A new preprint from researchers at Princeton University, the University of Hong Kong, and the World Resources Institute says the math might be wrong. ...

CDR Daily Digest — March 19, 2026

Five stories today — ranging from a serious accounting warning for biomass credits to the EU putting rules on paper for carbon removal certification. ⚠️ Biomass Carbon Credits Face an Accounting Crisis#Biomass Carbon Credits Face Accounting Crisis Before They Even Scale 88% of all carbon removal credits sold involve biomass. A new CATF report examined 25 certification protocols for biomass-based CDR — and found nearly all have significant accounting flaws. The voluntary carbon market already crashed once from sloppy accounting in the offset era. CDR can’t afford a repeat. Getting biomass carbon accounting right now, before the market scales further, isn’t optional. ...
