I appreciate the amount of thought that went into the creation of this tool, yet it is limited to land-based BECCS technology. Reworking this BECCS Doughnut tool to encompass marine BECCS technical options should give the policy makers a much more realistic view of the STEM, policy, and socioeconomics benefits of the general BECCS field.

Ignoring 71% of the surface area of this planet, ignoring the vast scale potential of the water, energy, and nutrient nexus resources provided within that 71% of planetary surface area, and ignoring the unique governance aspect of the high seas doesn't offer as useful of a planetary C management tool as one that includes the full range of BECCS options. 

I recommend that a 'Blue Biochar' ring be added to the land centric BECCS doughnut model.

[RWL1:  I agree totally.  In my reading of the same paper today,  I came to the same conclusion re biochar.   I will shortly be saying the same as I forward Andrew’s message to the biochar list (I forward a lot of them).

Ignoring 71% of the surface area of this planet, ignoring the vast scale potential of the water, energy, and nutrient nexus resources provided within that 71% of planetary surface area, and ignoring the unique governance aspect of the high seas doesn't offer as useful of a planetary C management tool as one that includes the full range of BECCS options. 
[RWL2:   I am sure this same approach for marine CDR would be very helpful to many of us.  But this Master's thesis assumes BECCS fitting into the electricity production part of the energy world.  And ocean CDR rarely includes 100’s of MW electric.  Electricity fits partially for biochar - but biochar doesn’t include the important underground CCS of this thesis (nor soil depletion, etc).  

At first I was wishing that Mr. Tress had included the word “biochar, but that could have increased his work load by an order of magnitude.  He did apparently (I’m still reading) a very good job of creating a “Haworth” donut specific for BECCS.  For sure that donut for biochar (as for oceans) will be similar but different.  

I am unaware of any similar use of Dr. Raworth’s contribution to (among many others) CDR.   But hope someone can recommend others.  Dr.  Raworth has added an important layer to CDR, so very glad to see this thesis, which covers many dozen pertinent CDR and Donut topics.

I recommend that a 'Blue Biochar' ring be added to the land centric BECCS doughnut model. 
[RWL3;  Thanks for your plug for the word “biochar”. (There are slight allusions in this thesis.).  

I don’t think we can “add"; the donuts will be different.

Ron, et al.,

I see your point.

I could never work out a way to translate Dr. Raworth's work directly into mCDR technical terms as his work is far more strategic in nature than being technical, yet  Mr Tress has provided a Raworth-like model for building donuts for different tech combinations. 

If the different tech models use the same nomenclature, largely the same assumptions, and the same definitions we may end up with a more standardized working language and development strategy for the CDR field in general.

I was clearly wrong in viewing his work as an end-product as it is more of a road map demonstrating how different tech combinations can be viewed under largely equal terms. That is exciting.

Best regards
