Researchers propose using “wood vaults” to store carbon by burying wood to prevent decomposition, potentially sequestering up to 10 gigatons of CO2 annually. Further study is needed to assess the method’s environmental impacts and scalability.
Inspired by the discovery of an ancient buried log, researchers have developed a new method to capture and store atmospheric carbon for centuries. The technique involves sealing woody biomass in “wood vaults,” offering a potentially cost-effective way to combat climate change.
Achieving net-zero carbon dioxide (CO2) emissions is crucial for combating climate change, yet reducing fossil fuel emissions alone is insufficient to meet the Paris Agreement’s targets. To achieve these goals, carbon dioxide removal (CDR) methods must be implemented, including engineering solutions, like direct air capture, and nature-based approaches, such as reforestation or afforestation. Forests play a crucial role in the climate change discourse as significant carbon sinks in natural carbon cycles, sequestering atmospheric carbon through photosynthesis.
Limitations of Natural Carbon Storage However, the carbon stored in wood via this natural carbon cycle is often quickly returned to the atmosphere due to decomposition or burning of biomass, leaving little net impact on atmospheric carbon. It is unknown whether carbon-storing woody biomass can be preserved long enough (hundreds of years or longer) to have an appreciable effect on reducing anthropogenic CO2 in the atmosphere.
Here, Ning Zeng and colleagues explore the viability of a CDR strategy involving burying sustainably sourced wood in an engineered structure called a “wood vault” to prolong the duration of carbon storage by preventing decay and decomposition. This novel method was inspired by the discovery of a remarkably preserved 3775-year-old Eastern red cedar log buried in clay soil in Quebec, Canada – a find that demonstrates the potential for long-term carbon storage through wood burial within certain environments.
Research Findings and Carbon Storage Potential By comparing the ancient log to a modern sample from the same species, Zeng et al. found that, despite being buried for nearly 4 millennia, the ancient wood had only lost up to 5% of its carbon, likely due to the low permeability and anoxic nature of the compact clay soil in which it was buried. Using carbon cycle modeling and forestry data, the authors estimate that up to 10 gigatons of CO2 could be sequestered via wood vaulting annually, using trees as well as underutilized wood residues, such as urban tree waste and forest byproducts from commercial thinning.
The authors also estimated an initial CDR cost of only $100 to $200 per ton. “A full life-cycle assessment is needed to quantify the net emissions and environmental impacts across ecosystems, supply chains, and engineered wood vaults, as well as to understand how these impacts vary by location and wood sources,” writes Yuan Yao in a related Perspective. “These understandings will be critical to developing biomass burial projects on a global scale.”

if you liked fiat money, you’ll love carbon credits.
OFFS! Guessing there’s SO much money to be made this won’t go away until the meteor strike.

Great idea — greenies can donate to the cause of buying up billions of cords of firewood and storing them on ice for centuries. Meanwhile, the rest of us can ignore the issue forever.
Another way to do the exact same thing is not recycle paper.
I’m afraid that the “carbon” they want to put into the boxes are people they don’t like.
Bulldoze the Amazon!
Educated idiots yammering to a mindless mass of sheeple about trying to control Mother Nature.
Spending trillions in the process and dreaming up outlandish schemes those same sheeple then embrace?
Absolutely ridiculous.
A couple of obvious false assumptions in that clause.
The human race has lost it’s mind.
They could achieve their goal just by planting fast growing trees...........
What a joke. Somebody will get rich (like Al Gore).
Pretty much..............
Mars atmosphere is 95% carbon dioxide................
Destructive solutions for non-existent problems, that’s what we need.
Now if Chevy Chase had a log, a yule log, not in the sense you may think of a log....

Burn and bury the Paris Agreement. Problem solved. No muss, no fuss.
