Potential relevance to BECCS? However, making molecular CO2 from dilute sources
is still no slam dunk as noted by Tony:
"Tony Marshallsay 11th October 2016 at 12:20 pmAs a CCS skeptic, I have the
1. “claimed” $30/tonne: The proof of the pudding is in the eating
2. “reduce… to $10/tonne by 2018”: Wishful thinking
3. “zero-emission” because captured CO2 reused locally: OK – much better than
sweeping the dust under the carpet.
4. “20% reduction in energy costs”: Presumably relative to use of another
(unspecified) solvent in a similar process for the same quantity of capture?
5. “8 times less solvent loss”: I dislike this fashionable expression, which is
open to misinterpretation. Why didn’t they say so many % reduction, as for
6. The environmental impact of the lost solvent (unspecified but identified in
linked article as APBS – a very variable mixture of possibly toxic chemicals)
is not mentioned.
7. “7 times reduction in corrosion”: See #5 above.
8. Has the cost of regular replacements for corroded parts (together with the
environmental impact of their production) and of the plant refurbishment and
downtime (during which I assume capture will be maintained by a standby?) been
included in the $30 figure?
9. For comparison purposes, what would be the carbon footprint (tonnes of CO2)
of the manufacture and installation of this proposed CCS plant?"
GR - How much cheaper and safer would it be to make products directly from CO2
without having to recycle expensive, corrosive, toxic chemicals - e.g. Skyonic,
