Definitions

  • Autotrophic, non-photosynthetic organisms can utilize the energy stored in various metal ions that are common in minerals. Apart from energy these organisms need a source of carbon atoms to produce biomass. Autotrophs typically start with oxidized carbon, i.e., carbon dioxide or carbonate as the source of their carbon. The autotrophic organisms reduce the carbon and thus produce biomass, which can then be incorporated into useful hydrocarbon fuels to provide the energy for the transportation sector. In order to close the carbon cycle, the carbon fed to the autotrophs must come from the oxidized carbon, i.e., carbon dioxide or carbonate as the source of their carbon. The autotrophic organisms reduce the carbon and thus produce biomass, which can then be incorporated into useful hydrocarbon fuels to provide the energy for the transportation sector. In order to close the carbon cycle, the carbon fed to the autotrophs must come from the
  • Autotrophic, non-photosynthetic organisms can only grow if they are provided with a continuous supply of inorganic carbon that can be converted into cellular material and eventually into electrofuels.
  • the sustainable use of these fuels without accumulation of carbon dioxide in the atmosphere requires that the carbon dioxide resulting from their consumption is recaptured from the air and recycled.
  • a highly efficient air capture system for carbon dioxide could remove the most difficult supply bottleneck in any autotrophic bioreactor system and with chemotrophic organisms allow for a system design that is far more compact than a photosynthetic bioreactor could ever be.
  • the disclosed subject matter includes methods and systems for feeding carbon dioxide captured from air to autotrophic bioreactors. Carbon dioxide is captured directly from the atmosphere and used to produce a carbon-enriched solution that is fed to chemotrophic organisms.
  • Non-photosynthetic autotrophic organisms provide a novel avenue toward bio- derived energy and liquid fuels. These organisms use inorganic building blocks, like carbon dioxide and water to form biomass.
  • the biomass is the first step in fuel generation.
  • the energy required to produce this biomass is typically derived from the oxidation of certain minerals containing for example sulfur, iron or hydrogen that can be oxidized in the presence of oxygen. Because they feed on minerals, these organisms are also known as lithotrophs. They consume water and carbon dioxide to produce biomass, which then can be converted into fuel. Thus, one must feed them not only the minerals that provide the energy but also the carbon dioxide that is to be converted into fuel. This carbon dioxide must ultimately come from the air, because at the point of consumption the carbon dioxide that is produced from the fuel is released to the air. It will accumulate in the air unless some action is taken to remove it again. BRIEF DESCRIPTION OF THE DRAWINGS

  • System 100 includes the following interactive components: a carbon dioxide collector 106; a regeneration unit 108; and an interface unit 110.
  • Carbon dioxide collector 106 includes filter units 112 having anionic exchange resin 114 for capturing carbon dioxide 116 from ambient air 118.
  • Anion exchange resin 114 is typically fabricated so as to readily absorb carbon dioxide 116 when substantially dry and release carbon dioxide when it is exposed to moisture.
  • a dry anion exchange resin 114 absorbs carbon dioxide from the air. When wetted, resin 114 releases carbon dioxide against a backpressure of about 0.1 bar.

  • the carbon dioxide is transferred to a solution thereby forming a carbon-enriched solution by rinsing the anionic exchange resin loaded with the carbon dioxide with water thereby releasing the carbon dioxide into air adjacent the anion exchange resin.
  • the resin is rinsed with either a carbonate or a bicarbonate solution instead of water.
  • the carbon dioxide in the air adjacent the anion exchange resin is contained thereby forming a carbon dioxide-enriched air.
  • the carbon dioxide-enriched air is about five percent carbon dioxide by weight.
  • a water wash also drives the carbon dioxide off the resin, but the solubility of carbon dioxide in water is small and unless the water volume is very large, the carbon dioxide is released from the water into the surrounding gas volume. If the resin during the wash is confined to a closed space, the carbon dioxide partial pressure in the head space above the water will gradually approach a partial pressure of five to ten percent of an atmosphere.
  • the moisture swing has a number of practical advantages, which become of particular importance in the context of feeding autotrophic organisms the carbon dioxide they need.
  • the moisture swing in its current implementation can only produce carbon dioxide at sub-atmospheric pressure.
  • production of pure carbon dioxide requires chambers strong enough to pump the air out of, and pumps and compressors to take low pressure carbon dioxide to liquid density.
  • In feeding autotrophs it is, however, quite sufficient to produce carbon dioxide enriched air, or an aqueous solution in equilibrium with carbon dioxide enriched air. This greatly simplifies the design of the system and removes nearly all of the energy requirement that is present in a system to produce pipeline-ready carbon dioxide.
  • the carbon dioxide partial pressure one can reach in the current system is between 5,000 Pa and 10,000 Pa, i.e. between 5 and 10 percent of atmospheric pressure. This is more than sufficient for feeding autotrophs.
  • the moisture swing absorption system is ideally suited to this application and will result in an extremely energy efficient implementation, which we will discuss in more detail below. In short, the dominant energy consumption in the system will be in the water preparation for the moisture swing.
  • the carbon dioxide-enriched air is placed in contact with a nutrient solution thereby forming the carbon-enriched solution.
  • the nutrient solution is prevented from contacting the anionic exchange resin.
  • the anionic exchange resin loaded with the carbon dioxide is rinsed with a solution recycled from the autotrophic bioreactor thereby forming the carbon-enriched solution.
  • the rinse solution is substantially free of chlorides and sulfates.
  • the carbon-enriched solution is fed to autotrophic microorganisms in the autotrophic bioreactor.
  • some embodiments include a method 300 of producing a biomass precursor to a biofuel using feedstock including carbon dioxide captured from ambient air.
  • carbon dioxide is captured from ambient air by exposing the ambient air to an anionic exchange resin thereby loading the anionic exchange resin with carbon dioxide.
  • the carbon dioxide is transferred to a solution thereby forming a carbon-enriched solution by rinsing the anionic exchange resin loaded with the carbon dioxide with water thereby releasing the carbon dioxide into air adjacent the anion exchange resin.
  • the resin is rinsed with either a carbonate or a bicarbonate solution instead of water.
  • the carbon dioxide in the air adjacent the anion exchange resin is contained thereby forming a carbon dioxide-enriched air.
  • the carbon dioxide-enriched air is placed in contact with a nutrient solution thereby forming a carbon-enriched solution.
  • the anionic exchange resin loaded with the carbon dioxide is rinsed with a solution recycled from an autotrophic bioreactor thereby forming the carbon-enriched solution.
  • the rinse solution is typically substantially free of chlorides and sulfates.
  • predetermined minerals are provided depending on a variety of factors including the type of biofuel that is desired. In some embodiments, the predetermined minerals include at least one of sulfur and iron.
  • the carbon-enriched solution and the predetermined minerals are fed to predetermined autotrophic microorganisms capable of oxidizing the predetermined minerals.
  • the autotrophic microorganisms and predetermined minerals are positioned in an autotrophic bioreactor. In some embodiments, the autotrophic microorganisms and predetermined minerals are positioned in situ at the natural location of the predetermined minerals. In some embodiments, hydrogen is produced during oxidation of the predetermined minerals by the predetermined autotrophic microorganisms and ultimately consumed by the microorganisms.
  • Non-photosynthetic, autotrophic processes have a fundamental advantage over photosynthetic processes, because they do not rely on dilute sunlight to operate.
  • the output of chemotrophic bioreactors can scale with the volume of the reactor vessel, which stands in contrast to algae bioreactors whose output scales with the surface area that is exposed to sunlight. It is possible to create large reactor vessels that are deep and thus can have a much smaller footprint than algae ponds. A large autotrophic reactor can be made more compact until it reaches the next binding constraint, which typically is access to the carbon dioxide that provides the raw material for producing fuel. Thus autotrophic reactors, even more than algae reactors, benefit from the delivery of carbon dioxide from external sources.
  • Biological systems take advantage of a large variety of pathways for utilizing energy that is present in the environment. Photosynthesis is the most dominant pathway, but there are also many chemical pathways available to a great variety of organisms that are known as chemotrophs. Chemotrophs are quite common. For example, it is well known that chemotrophic autotrophs form the foundation of a fostering ecological food chain around hydrothermal vents in the deep ocean. Sulfur oxidation is the largest contributor of energy in these ecosystems, but it is known that iron oxidation and manganese oxidation also play a role. In some situations, in which sulfur is rare, organisms that oxidize iron to drive their metabolism provide the dominant source of energy.
  • a major advantage of chemotrophic bioreactors is that they can be very compact. Thus, the rate at which carbon dioxide can be provided rapidly becomes rate limiting. This already poses a serious problem to algae farms, which cannot become as compact as chemotrophic bioreactors because they rely on sunshine for their energy source. Since direct chemical capture of carbon dioxide from the air can achieve uptake rates three orders of magnitude higher than photosynthetic organisms have achieved, air capture can go a long way in mitigating the carbon dioxide bottleneck.
