This is a complete ecosystem of reactors which I previously uploaded in detail one by one, what is uploaded here is the integration to become a solution that we call Integrated Carbon Capture and Utilization for Regenerative Energy (ICCURE).

The first is in the top left corner, Autothermal Slow Pyrolysis (ASP) - which is the process of carbonizing biomass into charcoal. After undergoing the activation and functionalization process in the same reactor, this charcoal will be ready to become an adsorbent in the CO2CAN reactor, and a reactant in the OCCYRE reactor.

The second is the CO2CAN reactor, whose function is to capture and bind CO2, both from within the ICCURE ecosystem itself and CO2 from other emission sources. CO2 will be stored by CO2CAN in the form of adsorbate - CO2 which is bound to the adsorbent. This bond is only released when CO2 is about to be used for further processing.

The third is the OCCYRE (Onboard Carbon Cycles for Regenerative Energy) reactor, which is a reactor where CO2 in the form of adsorbate is debonded by heat and reacted with charcoal produced by the ASP reactor. Through the Boudouard reaction, C + CO2==>2CO, the result is CO gas which is the main component of syngas and building blocks for all subsequent forms of regenerative energy.

Fourth is the XH2 (Extra High Hydrogen) reactor, which processes CO gas from OCCYRE through the Water Gas Shift (WGS) reaction, CO+H2O==>H2+CO2, the main result is hydrogen (H2), with byproduct in the form of CO2. This CO2 is then withdrawn back into CO2CAN to be stored in the form of adsorbate again, to become raw material for the next CO gas production process.

Fifth is the GTX (Gas To X) reactor, which processes some of the syngas and H2 with a minimum ratio of H2/CO>2, to become hydrocarbon fuels such as gasoline (GTG), diesel (GTD), jet-fuel (GTJ) and LPG (GTL).

Even though this hydrocarbon fuel is exactly the same as fossil hydrocarbon, this one is regenerative - it can be regrown again, namely use CO2 to regenerate CO gas through the OCCYRE reactor mentioned above.

As the ultimate feedstocks for this regenerative energy are only biomass, CO2 and water, clean and affordable energy as per SDGs no 7 - should be achievable long before its due in 2030!
