XPRIZE Carbon Removal Challenge

A Worldwide Hectare Homestead Act for the 21st Century
Summary of Intent to Image
By any reasonable civil right everyone who has a desire to live and work a single hectare of land needs to have one, for the sake of humanity's futurity.

Therefore, to begin, we purpose that there are presently the means for all unaccompanied climate refugee children and forest guardian asylees to be expeditiously ceded a hectare of land in their name. This to be paired with a vocational offer featuring indigenous legacy for guidance in place-based self-sufficiency, domestic biochar production and regenerative utility maintenance. As a pilot project for all future willing and able refugees it will presage the nexus of interactions that an equitable zeitgeist world culture will experience in transiting the 21st Century. The future of the future is the present.

The Xprize carbon removal 'land' category has almost 300 entries where a significant number have biochar/soil as their primary instrument. Clear evidence that the science is in and the word is out about biochar's high-integrity in the durable natural climate solutions catalog.

Our Xprize intent is to portray the OnePlanet biochar hectare homestead (OPBH2) as a most holistic and rational pathway to an enduring gigaton culture.


 
Some very round ballpark numbers we want to put into plug and play:
  • select and vet 500 NGO allies and stakeholders for organizational agility.
  • begin acquiring access to 500mn hectares for 500mn one planet family biochar treefarm homesteads - that's almost 2mn sq. miles, mostly distributed throughout the northernmost and southernmost temperate zones. 

  • begin resettling 100mn refugee children in the next ten years, @ 10mn turnkey homesteads a year.

  • At 1 tonne of biochar per hectare per year, 500mn hectare homesteads can sequester ~1500mn tonnes of CO2e, annually, conservatively, and further

  • the same 500mn hectares as oneplanet homesteads can sequester another >1500mn tonnes through tree farming, food forests, place-based emissions avoidance, stacked functions, shrunken externalities and sovereign soil co-benefits.

  • 1500mn tonnes x 2 = 3 gigatonne@year, conservatively. That's 3000mn tonnes of CO2e annually, mostly off-grid, by 2050. Come, run, see!

  • Worldwide there are over 470mn <2ha family smallholdings/homesteads in situ. If not already, they are en mass recruitable to the oneplanet biochar sovereign-soil gigatonne cause, as well.


To win the grand Xprize, teams must demonstrate:
1. A working solution at a scale of at least 1000 tonnes removed per year;

  • A biochar homestead can make, at least, 1 tonne of biochar@year, therefore sequestering >2.5 tonnes of CO2@year, at least, with production emissions factored in.
  • It would take 400 biochar homesteads each making only one tonne@year to produce 1000 tonnes of sequestered carbon.
  • We can presume this to be easily happening worldwide and verifiable, right now.
       further notes
  • 1 tonne (1000kg) of biochar divided by 52 wks = 19.2 kgs@wk = 2.7 kgs@day (6 lbs).
  • 2.7kg@day average could be produced domestically with a biochar hearth.
  • 20kg@wk avg is easily accomplished with a homemade outdoor kiln.

  • A hectare can commonly and sustainably bring forth >20 tonnes of dry biomass, which equals ~4.5 tonnes of captured CO2e when pyrolyzed. 400ha X 4.5 = 1800 tonnes, conservatively.

2. Model their costs at a scale of 1 million tonnes per year;


If the above data is found feasable and conservative we would need 400,000 biochar homesteads to sequester
a million tons (a megaton) of CO2, just through low tech biochar production.

This can be fulfilled through our proposed homestead program and recruitments from present day smallholder / homesteaders worldwide.

Let's say that the avg cost of a turnkey refugee family hectare homestead is - all things considered - $1mn@, equalling $400bn (billion). USgov just spent over 6tn (trillion) on Covid.

3. And show a pathway to achieving a scale of gigatonnes per year in the future.

How many one planet biochar hectare homesteads (OPBH2) would it take to capture a gigatonne (a billion tonnes) of CO2 @year? We need 400mn hectare homesteads for a gigaton of reasons, including the full realization of a gigaton culture. Confronted with this number we can now propose the one planet biochar hectare to be the final coin of the realm.

XPrize continues:
"Any carbon negative solution is eligible: nature-based, direct air capture, oceans, mineralization, 
or anything else that achieves net negative emissions, sequesters CO2 durably, and show a sustainable
path to achieving low cost at gigatonne scale."

Our proposal fully realized will meet all the above criteria.
