Blue Planet.jpg

Blue Planet’s technology uses CO2 as a raw material for making carbonate rocks. The carbonate rocks produced are used in place of natural limestone rock mined from quarries, which is the principal component of concrete. CO2 from flue gas is converted to carbonate (or CO3=) by contacting CO2 containing gas with a water-based capture solutions. This differentiates Blue Planet from most CO2 capture methods because the captured CO2 does not require a purification step, which is an energy and capital intensive process. As a result Blue Planet’s capture method is extremely efficient, and results in a lower cost than traditional methods of CO2 capture.

Carbon XPRIZE.jpg


We’ve discovered the inexpensive transformation of the greenhouse carbon dioxide into a widely useful and highly valued product. In our C2CNT process, CO2 is directly transformed to hollow nanofibers, “carbon nanotubes,” products with remarkable properties of conductivity, nanoelectronics, higher capacity batteries, flexibility, with greater strength than steel and widespread use as carbon composites. The conversion of CO2 to pure carbon nanotubes provides the most compact form to capture carbon dioxide and mitigate climate change.

Carbon Upcycling Technologies.png


Carbon Upcycling Technologies Inc. (CUT) is a Canadian clean-tech startup based out of Calgary, Canada that is working on sequestering CO2 gas in a solid form while creating high quality graphite and graphene nanoparticles.

Carbon Upcycling.png


Carbon upcycling is based on the integration of several technologies into a closed-loop, to fabricate CO2NCRETE™, a near CO2-neutral construction material. The process is designed to efficiently utilize flue gas exhausted from point source emitters (e.g., power plants and cement plants), by efficiently recovering waste heat and enriching CO2 present in the gas stream. A novel binder system based on calcium hydroxide (hydrated lime) is mixed with aggregates and admixtures to form a shape-stabilized CO2NCRETE™ building element. The final, and key step lies in combining the captured CO2 with CO2NCRETE™ element via a carbonation reaction (i.e., CO2-mineralization) to form a solid building component. These elements can be used like Lego® to rapidly assemble buildings, bridges, and other infrastructure traditionally constructed with concrete.

Carbon XPRIZE.jpg


We convert carbon dioxide waste from power plants into drop-in liquid fuels by adding carbon from biomass and hydrogen from methane and using process energy from biomass.

Ingenuity Lab.jpg


Our approach borrows from what occurs naturally, namely photosynthesis. By utilizing the enzymes within plants, we are able convert atmospheric carbon dioxide to innocuous sugars by capturing a small amount of sunlight as an energy source, which is required to regenerate the consumable cycle cofactors ATP and NADH. If needed, a solar rechargeable battery could be used to produce enough light to run the reactor in the dark or at night and operate the control systems. The system is extremely environmentally friendly. All of the naturally occurring proteins used to run the reactor are produced by bacteria using recombinant DNA technology and are all biodegradable. The substrates we are currently using for immobilization are made of silicon dioxide or sand. Everything is self-contained, the same way it is within the leaf of a plant, and like plants there are no hazardous waste materials produced. By adapting the cycle, we further hope to convert these sugars to other chemicals with alternative industrial applications.

SkyMining first addresses the urgent problem of climate change by removing CO2 from the atmosphere and using it to produce a clean replacement for oil and coal. For the same USD 2 trillion that was invested in wind & solar during the past decade, SkyMining could have produced enough carbon negative fuel to replace all coal use and 30% of all oil.

Our mission is to establish atmospheric CO2 use in everyday life. We hope to initiate a positive shift in people’s perception: from CO2 as a potential problem to CO2 as an essential and incredibly versatile resource.

Our founders met at the European Space Agency (ESA) in 2008 where they were working as system engineers on the life-support project for the International Space Station, studying what would ultimately become Skytree’s technology.
