There are four marine CO₂ removal (#CDR) companies (2 OAE, 1 DOR, and 1 kelp) that are among the 20 finalists in the $100 million XPRIZE carbon removal competition.
For April Fools' Day, I was going to suggest a ridiculous CO₂ removal (#CDR) method but everything I’ve come up with has already been proposed as a real solution.
"MIT chemical engineers have devised an efficient way to convert carbon dioxide to carbon monoxide, a chemical precursor that can be used to generate useful compounds such as ethanol and other fuels."
@davemark a useful form of carbon dioxide removal that helps replace fossil fuels but will it help reduce the excessive amounts of greenhouse gases in the atmosphere? #co2#CO#cdr#fossilfuel#climatechange
There are proposals to implement enhanced rock weathering on farms for CO₂ removal (#CDR), and studies have shown that spreading rock dust on farmland can boost crop yields and help increase fertilizer use efficiency.
It's no wonder people confuse carbon capture and sequestration (#CCS) with carbon dioxide removal (#CDR). The people naming these CDR techniques keep calling them direct air CAPTURE and direct ocean CAPTURE.
Use Direct Air Removal and Direct Ocean Removal instead!
Did you know that Britain is starting to install power cables from solar farms in the Sahara to their island nation? Well, now you do
The ship that is going to install that 10,000 miles of cable isn't even built yet though so it's going to take some time to do at 100 miles at a time once the ship's constructed and the cables are manufactured
Anyways, that's quite a commitment to procuring clean electrons. I expect the cable factory and the ship end up being good investments
Germany is getting closer to starting to pump CO2 underground to keep it out of our already polluted atmosphere.
Habeck, a member of the environmentalist Green party, recalled opposition to carbon storage when it was discussed in the 2000s. But he said “the technology has been developed further ... and from my point of view it is mature and safe," and that it is now being used elsewhere, not just in research projects.
So, I'm quite resigned to not being able to entirely restore the reputation of carbon offsets using carbon dioxide with everyone and I entirely appreciate the damage that has been done to this budding new part of the circular economy we need to transition into.
@jgkoomey@matthewtoad43 since y'all have been some of the fiercest opponents to this new industry, I'm curious what you think of this American University's group rebranding.
To me biochar is one of the most promising Direct Air Capture Carbon Dioxide Removal technologies because it is so accessible to the most people to take part in especially all of the farmers that we need to recruit into the struggle to transition away from fossil fuels and to minimize greenhouse gas emissions.
Someone should air a CO₂ removal (#CDR) commercial during the Super Bowl because if CDR’s gonna happen, it has to evolve from something that almost no one’s heard of to the largest industry the world has ever known in a relatively short time.
I talked to Todd Woody from Bloomberg about Banyu Carbon, a marine CO₂ removal (#CDR) company that is working on using photoacids for direct ocean removal (DOR).
It seems promising, but the challenges of DOR include the ecological impacts of sucking in so much seawater, making sure removed carbon is permanently sequestered, and MRV.
We need CO₂ removal (#CDR) to reach net zero, but it's incorrect to say we must ramp up both decarbonization and CDR today.
Minimizing CDR deployment will decrease fossil fuel use, greenhouse gas emissions, and air pollution.
For climate and human health, we should focus current efforts on deploying renewables, electrification, carbon-neutral/negative fuels, and efficiency, instead of betting on our ability to scale CDR in the future.
This graph of falling prices for batteries is all the reason anyone should need to justify making the decision to pause building new LNG export terminals.
Renewable energy and storage can replace all of our fossil fuel use for electricity production, heating, and industry.
This isn't a novice-level entry into the world of biochar and its potential role in helping to reverse the global warming we've caused and the two presentations are quite bland by most modern standards, but I really like this graphic that Nikolas Hagermann shared to help explain pyrolysis. https://youtu.be/WHIVyx9-HlY?si=rKcazC7ZgMiMpKQX
I also quite liked that he showed the snowboard built using biochar that won a medal for its rider
If the estimate is correct, it would take 14 billion tonnes of olivine to remove 10 billion tonnes of CO₂ from the atmosphere. This is a CO₂ removal (#CDR) target for 2050.
We currently ship 11 billion tonnes of goods every year. Imagine shipping 14 billion tonnes of olivine on top of that.
Ocean alkalinity enhancement is a promising marine CO₂ removal (#CDR) technique, but in this important new contribution, @bach_lennart points out that adding alkalinity could decrease natural alkalinity sources, creating an additionality problem.
This happens because anthropogenic alkalinity increases the calcium carbonate saturation state, which reduces the dissolution of calcium carbonate from sand, a natural alkalinity source.
Roads2Removal.org is a collaborative public outreach initiative from Climate Now and the Livermore Lab Foundation trying to help us to save our planet by scaling up our drawdown of carbon dioxide out of our atmosphere.
Humans have always treated the ocean as a dumping ground: toxic chemicals, munitions, plastics, and now we want to dump massive amounts of terrestrial biomass in the ocean for CO₂ removal (#CDR).
Africa and South America a 'blindspot' in carbon removal research, study reveals (www.imperial.ac.uk)
A review of research on carbon dioxide removal reveals a lack of evidence on its costs, impacts and benefits in Africa and South America....
