Abstract

CO2 captured from the air (DAC, or “Direct Air Capture”) , it is the most effective capture of many senses, being natural diffusion to and inside open ponds and can be collected and/or stored either in cycle in a form of  CaCO3 sediments, further thermolysed, or by biomass as an alternative. Such CO2 can be used as a raw material for artificial carbon based fuels production for distributed zero carbon powering, and to reach energy independency and safety.

 

Such ponds’ CO2 is concentrated and clean and is 1144 kWh/ton of about 900 C and up to 320 ton per m2 of these ponds [1], while such energy can be very cheap renewable clean one, can  be cheaper USD 0.01/kWh by different ways being developed too.   

 

Electricity of USD 0.01/kWh or cheaper is impotent criteria, that allows  zero carbon powering by carbon based liquid or gaseous fuels at competitive price cheaper USD 70.0 per a barrel of oil equivalent. It is synthetized from such cheap clean and abundant and inexhaustible CO2 not needed in a long transportation, if being nearby such renewable energy power plants with nearby such artificial carbon based fuels manufacture from such CO2 and H2 produced by clean water splitting either by the alkaline electrolysis or by concentrated rays of magnetrons, the both being very cheap and very energy effective and compact mass produced and simple devices.

 

For such CO2  storage’s needs it would be very fool and potentially dangerous deal to store it in grottos in its gaseous form, but being convenient to store it in a form of biomass as for long CO2 storage, as for different applications, including for carbon bases fuels’ production, for further zero carbon powering. Surplus CO2 concentration in the air for greenhouse can sufficiently increase and cheapen the biomass yield.  Moreover, especial circulation water channel system to grow small aquatic plants (e.g. Lemna Minor, Azolla), plankton , microalgae at its exponential part of grow rate curve, can triple biomass harvesting.
