How Biochar Removes CO2 From The Air — And Helps Farmers Thrive | Axel Reinaud | TED
Biochar is a kind of charcoal that removes CO2 from the atmosphere, helping yield healthy crops and even producing abundant renewable energy in the form of electricity as it’s made. This exciting climate change fighter is ready for scaling now. Entrepreneur Axel Reinaud outlines three ways to make this material more accessible to farmers —…

Does the biochar requires energy (for heating) to be produced? How much, and from what source?
Matt V
March 2, 2022 at 5:20 pm
No, it actually produces excess energy. Volatile compounds in the biomass are burned, which creates heat and leaves behind carbon (biochar or charcoal).
Daniel
March 2, 2022 at 11:48 pm
@Matt V Right, the only energy input it needs is the flame that starts the fire (i.e. a Zippo lighter or match). The rest all comes from combustion.

@Daniel no, that would be with normal burning (using oxygen), which releases carbon.
If you watch until the second half, it requires energy to start the pyrolysis, but capture of the flammable gases makes the net energy usage negative

Carbon is life so if you take carbon away you take life away. Carbon dioxide makes plants live so anyone who is vegan should be very worried about getting rid of it. I hear lots of people talking about climate change and only talking about taking co2 from the atmosphere but nobody is talking about all the chemicals and heavy metals getting sprayed in the skies all day every day that is poisoning the earth and everything that lives here as well as blocking out the sun which all life needs to survive. Wake up people you are being taken for a fool and helping them kill you and everything else off for good if you go along with these lies. Humans have been around for hundreds of millions of years but keep getting wiped out by the same kind of people who are trying to wipe us out now. History is lies along with everything you are being brainwashed to believe now. Something much more powerful and complex than humans designed this world and it works well enough on its own without humans trying to be the creator. Humans can’t even handle the force of water let alone anything else.

Simply packing it in a sealed metal box with an outlet valve and heating the box will do
Christian Panero

Usually in a pyrolysis plant a fraction of the biomass is burned to produce heat, or another fraction can be gasified to produce a syngas. Both the exhaust gases from the burner and the syngas produced by gasification do not contain oxygen and they are hot. So they can be used to heat up the biomass to produce char.

By removing CO2 from the atmosphere you are suffocating the plants that manufacture oxygen. If you do not have oxygen to breath then you suffocate also.

I am so very sorry, I have to admit it was me, I wen’t out the other epoch and silly me, I left the heating on full blast. Was such a bender that sesh, took me a million years or so to get home and turn it down.
freemanjack msiradio
March 2, 2022 at 9:49 pm
@Dusty McGuire Can I ask you to consider the vast volume of water the oceans would have had to swallow, given any sea ice does not add to the level in the same way melting ice does not brim a glass if it melts, so all those mega kilometers of water volume can only have occupied the most northern and southern land masses (lets give it a generous half the total land mass @5% total area) so we need to explain a 95-5 volumetric increase ie; 90% of the planet rose by hundreds of meters with a volume ONLY drawn from 5% of its surface!
Florian Hansch

@freemanjack msiradio that’s actually quite interesting because I never crunched the numbers until now, but it doesn’t really add up, it’s like a drop in the ocean (no pun intended)

Trees are carbon neutral.
freemanjack msiradio
March 2, 2022 at 9:39 pm
@Krystal so is biochar ultimately, all biology decays, decay releases sequestered carbon, biochar merely slows that process but then so does simply planting more trees, wood fuel should count as ‘carbon neutral’ in reality which might drive far better change than its listing as a pollutant.
Krystal
March 2, 2022 at 10:17 pm
@freemanjack msiradio As long as large trees are not planted in the suburbs, this has caused property damage, destruction and major maintenance on these properties. Where I live, everybody planted trees in the 1980’s because our Prime Minister told everybody we had to plant a billion trees to save the planet. The trees surrounding me, actually affect my insurance, and I don’t even have any trees. I can see in the next ten to 20 years the tree problem here will become massive.

March 2, 2022 at 10:43 pm
@Krystal Agree entirely, in south east london we are now overrun by a canadain maple used as a decoration for a royal visit that never happened in ’77, now if all those trees were treated as a man made forest and harvested on a 12 year cycle, none of this would be problematic and home owners could be compensated by selling their low grade timber for fuel wood.

Ill informed bunkum, biochar is a wonderful soil conditioner, however the sequestering of the initial charcoal into the soil column ‘increases microbial activity and biodiversity’, ANY biological action outside of the oxygen produced by oceanic blue green algae PRODUCES carbon dioxide as a net output, carbon dioxide is the gas of life, continually cycled to generate every cellular function. Just as an fyi, the Amazon is NOT the ‘lungs of the world’ it like every other land based life, has a carbon net zero, if you want to sanctify any part of the planet, the subsurface of the oceans is where to look, not only does this ecosystem generate ALL available excess oxygen (due to the gaseous bubbles rising from their source to the surface into the atmosphere) it also feeds the diatoms whose skeletons are sequestered carbon in the form of calcium carbonate which slowly rains on to the sea floor.

Oh we finally figured out how to use energy to put carbon back to the ground? Thats almost as cool as not digging it up and burning it in the first place.
Peter Clark

CO² is airborne fertiliser for plants that photosynthesise. A vital element for continued life above ground. The Carboniferous (the most productive period in Earth’s history) had levels up to 7000ppm; and it laid all the oil and coal.
A shortage of CO² costs the plant internal water because the stoma have to remain open longer to get the essential snack.
Biochar: requires burning organic matter which releases CO².
The most complete solution to Earth’s problems are contained in the principles of Regenerative Agriculture (RA) because life on Earth is a dynamic system that requires consumption, recycling and regrowth. Once you grasp the interweaving of all the processes of RA we can see a path to the reversal of all of the man-made deserts; which is all of them, they are not natural. New growth sucks up CO² fast.

Or he could produce it himself and sell it to his neighbors.
He will donate his waste product and pay to get it back? Hmmm wonder why this is suggested in Africa and not Arizona or Texas or California? Why, because the plan is probably to exploit.

Um, how is this any better than just mulching or composting dead plants? How is generating _more_ heat a good thing? Lots of other things already generate heat (eg electronics), why not try to capture or divert those unavoidable sources of heat instead of making more? If you want to burn plants (hopefully already dead), then at least try to find ways to reduce how much heat other stuff (like lighting and transportation) generate.
