[0023] FIG. 1 provides a schematic drawing representing an overall system view of the present invention. The present method and system may use a combination of existing and new technologies or may rely on new technologies to achieve a lower-carbon, carbon negative, or carbon neutral result. Potentially part of the overall system is the use of a bio-refinery 102 which generates converts biomass to fuel 112 and, in the process, produces some amount of CO2. A portion of the CO2 may be captured by a system 103 and then sequestered as part of the same system or different system 104 such as through the use of a pipeline for storing CO2 in the ground.

[0024] Fuel 112 from the bio-refinery, such as biodiesel, renewable diesel, renewable naphtha, renewable propane, bio-methanol, bio-ethanol, bio-propanol, bio-ethanol, or other renewable or bio-based fuel known to those skilled in the art, are provided to a combustion-powered device 170 to an engine control module 175. The surrounding 115 is in this embodiment air which may be encountered in a metropolitan, industrialized, or rural areas and may contain any level of pollutants and particulates. The incoming fuel/air then passes through the internal combustion engine (ICE), particulate filter, and the NOx control 120 which will then generate an air level having a pollution calculation. The air continues to an emissions capture device which includes a CO2 capture device 130, which may be a mechanical, chemical or electrical system designed to remove various components from the air. As the exhaust is exiting the combustion-powered device it is measured by one or more sensors 140 which detect the various components contained in the air/exhaust and compares the levels with the first pollution level to provide a score.

[0025] FIG. 2 shows a block diagram setting forth an exemplary method of creating a comparative score though uses of a lower-carbon, carbon negative, or carbon neutral system for combustion-powered devices. The method begins by providing a plurality of lower-carbon, carbon negative, or carbon neutral combustion-powered devices at step 200. There may be a step of calculating the pollution value of the surrounding and incoming air at step 205. A score relating to the collective use of the combustion-powered devices is created at step 210. A database is accessed at step 220 and the database may include different information concerning performance against other types of combustion-powered devices, other entities in the data collection area, historical data generated by the user from prior years and other useful information. In addition, other databases may be provided at step 225 which includes a database housing governmental standards and at step 227 which may include information of currently available proposal or opportunities for an operator to bid on. Any one or all of the databases may be utilized in connection with an assessment of the combustion-powered devices. Next, at step 230 the emission score is analyzed from the selected standard or other data from which a comparison is to be made. Finally, at step 240, a report is generated based on the comparison and analysis conducted in step 230. The report may be used for example in the operator submitting a bid for an outstanding governmental or customer request, or to show compliance with local emission standards or to obtain tax or other credits or incentives which may be offered by a governmental agency or sponsoring organization or to prove the operator is achieving lower carbon emissions.

[0026] FIG. 3 provides a schematic 300 of a system for treating polluted, contaminated or other high carbon content air. Ambient air 310 containing one or more pollutants, contaminants or other elements is enters the combustion-powered device 320 via a treatment system 315 which will begin the process of removing designated contaminants. The incoming air 310 is measured by measuring device 317 to determine the level of pollutants or other contaminants in the air. Partially treated air 323 may be released at a first port 321 which has a first set of pollutants or contaminants removed. Treated air 330 may be released through second port 327 after passing through a second treatment system 325 and the treated air may have all the pollutants removed. Each of the treatment systems 315 and 325 may use mechanical, electrical or chemical treatment processes in order to treat the air traveling through the systems or alternatively, one system may use a different system than the other system, e.g., one may use a mechanical system and the other a chemical system. Each of the ports 321 and 327 may have a measuring device 315 and 319 to measure the amount of pollutants still in the air that is leaving the combustion-powered device 320. The operator of the vehicle may elect to release treated air through either of the first and second ports 321 and 325 due to such factors as fuel economy or targeting a specific contaminant.

[0027] FIG. 4 provides a block diagram of a method for creating one of a carbon neutral, carbon negative, or lower-carbon environment and comprises the steps of initially providing a combustion-powered device at step 410. Next, ambient air which may contaminated with pollutants from a metropolitan or industrial area is received at an air intake point of the combustion-powered device at step 420. The incoming air may be measured at step 425 to determine the level of contaminants, pollutants and or carbon content or level. Once the measurement is obtained, the measurement is stored at step 427 for later comparison. The air is processed through a total capture device on the combust-powered device at step 430. Treated air is released from the combustion-powered device at step 440. Treated air may also be released by a second port at step 445. The treated air, being released from either the first or second port, is measured at step 450 to determine the level of carbon and or pollutants in the air. Next, the results of the measurements from the treated air is compared from the stored data of the incoming air at step 460. Based on the results of the treatment, the owner/operator of the combustion-powered device may request a credit or other benefit from a local, state or federal agency for improving the quality of air at step 470 of the metropolitan or industrial area where the air was collected.

[0028] FIG. 5 provides a schematic drawing representing an overall system view of the present invention. The present method and system may use a combination of existing and new technologies or may rely on new technologies to achieve a lower-carbon, carbon negative, or carbon neutral result. Potentially part of the overall system is biomass (500) that has, over time, biologically fixed atmospheric carbon dioxide (501) into a solid or liquid form. Through agricultural or industrial practices, the biomass (500) is then harvested, in all or in part, such that a biomass feedstock (502) is brought to a bio-refinery (510) for further processing. In some embodiments, a portion of the biomass (503) can be handled in such a way as to sequester the carbon in a carbon sink (590).

[0029] The portion of the biomass (502) that is brought to the biorefinery (510) is subjected to processing such that one or more fuel products (511) are produced. In embodiments, the fuel (511) is a carbon-containing renewable fuel such as biodiesel, renewable diesel, renewable naphtha, renewable propane, bio-methanol, bio-ethanol, bio-propanol, bio-ethanol, or other renewable or bio-based fuel known to those skilled in the art. In embodiments, the bio-refinery (510) also produces one or more byproducts (512) that contain a portion of the carbon initially contained in the biomass feedstock (502). In some embodiments, these byproducts (512) may optionally be handled in such a way as to sequester the carbon in a carbon sink (590).

[0030] Additionally, in the fuel production process the bio-refinery (510), may also emit carbon dioxide emissions (513). In embodiments, a portion or all of carbon dioxide emissions (513) may be captured and sequestered (514) using a carbon dioxide capture device known to those skilled in the art.

[0031] The fuel (511) is subsequently transferred to a combustion-powered vehicle or device (520) for the purposes of conducting useful work, such as transportation. Also directed to vehicle (520) is polluted air (531) containing primarily oxygen (O2), nitrogen (N2), water vapor, argon, carbon dioxide (501), and pollutants (530). Pollutants (530) typically contains some measureable amount of nitrogen oxide (NOx), sulfur oxide (SOx), particulate matter, hydrocarbon, heavy metals, and/or carbon monoxide. The exact composition of pollutants (530) will be known to those skilled in the art to vary based on a variety of factors such as season, geography, and time of day. The polluted air (531) being directed into the intake of vehicle (520) in order to feed combustion

[0032] In the process of conducting useful work, combustion-powered vehicle (520) combusts the fuel (511) and produces emissions, of which a portion can be captured and sequestered as sequestered emissions (522) prior emitting the remainder as tailpipe emissions (521) into the atmosphere. In embodiments, the composition of certain impurities are lower in the tailpipe emissions (521) than in the polluted air (531) entering the air intake of the vehicle. In preferred embodiments, the composition of the sequestered emissions (522) is primarily carbon dioxide.

[0033] FIG. 6 provides a schematic or drawing representing a further embodiment of the present invent by providing additional detail to the combustion-powered vehicle (520).

Air filter (615) may be composed of at least one of a porous absorbent material (such as cellulose, glass fiber, or similar material known to those skilled in the art) or porous adsorbent material (such as activated carbon, or similar material known to those skilled in the art) to purify the polluted air (531) such that the composition of cleaned air (616) is lower in pollutants such as nitrogen oxide (NOx), sulfur oxide (SOx), particulate matter, hydrocarbon, heavy metals, and/or carbon monoxide than polluted air (531). Cleaned air (616) is then introduced into the combustion engine (620). Meanwhile, the fuel (511) is introduced into a fuel storage tank (610) to be stored and subsequently introduced into combustion engine (620). In embodiments, the fuel storage tank (610) is comprised of a vessel for holding at least one of fuel (511) and other fuels, a method of conveying and dispensing the fuel (511) into the combustion engine (620), and a method for returning any unused fuel (511) back to fuel storage tank (610). In further embodiments, fuel tank (610) also includes a method for maintaining the temperature of the fuel (511) at a controlled temperature. The cleaned air (616) and fuel (511) that is introduced into combustion engine (620) then undergoes combustion to produce heat, pressure, and combustion products (621).

[0034] In embodiments, combustion engine (620) is a reciprocating piston engine (such as a spark-ignition engine or compression-ignition engine), a rotary engine (such as a Wankel engine), a continuous combustion engine (such as a gas turbine engine), or similar device known to those skilled in the art. Combustion engine (620) converts the pressure generated through combustion of the cleaned air (616) and fuel (511) to mechanical energy, which is then used to produce useful work. In embodiments, combustion engine (620) includes systems for enhancing the combustion performance such that the combustion approaches ideal conditions such that the combustion products (521) is comprised entirely of carbon dioxide and water.

In these embodiments, combustion products (621) is introduced to aftertreatment system (630) where the concentration of pollutants is reduced such that the concentration of pollutants in treated exhaust (631) is lower than the concentration of pollutants in combustion products (621). In additional embodiments, aftertreatment system (630) is comprised of a plurality of devices known to those skilled in the art to chemical modify or remove pollutants such as nitrogen oxide (NOx), sulfur oxide (SOx), particulate matter, hydrocarbon, heavy metals, and/or carbon monoxide. These devices may include at least one of a direct oxidation catalyst, selective catalytic reducer, catalytic reducer, particulate matter filter, particulate matter trap, or other device known to those skilled in the art.

[0036] In still other embodiments, the concentration of particulate matter in treated exhaust (631) is at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, at least 99.5%, or at least 99.9% lower than in combustion products (621).

In yet further embodiments, the sum of nitrogen oxide, sulfur oxide, particulate matter, hydrocarbon, heavy metals, and carbon monoxide is at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, at least 99.5%, or at least 99.9% lower than in combustion products (621).

[0037] The treated exhaust (631) is then introduced to total capture device (640) where a portion of the water vapor, carbon dioxide, and remaining pollutants are removed from the treated exhaust (631) to produce tailpipe exhaust (521). Total capture device (640) is comprised of one or a plurality of devices such as condensers, gas adsorbers (containing adsorbent media such as activated carbon, zeolites, polymers, metal-organic frameworks, and/or metal oxides), barrier filters, gas scrubbers, membrane separators, catalytic converters, or other means of gas purification known to those skilled in the art. As known to those skilled in the art, depending upon the selection of devices including total capture device (640), additional equipment or systems are necessary for the proper function of the device.

[0038] In some embodiments, total capture device (640) includes one or more gas adsorbers, configured in series and/or in parallel, wherein the adsorbent media is suitable to capture at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, or at least 90% of the carbon dioxide in the treated exhaust (631). In preferred embodiments, the adsorbent media in total capture device (640) is also suitable to capture at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, or at least 90% of the nitrogen oxide in the treated exhaust (631).

[0039] In other embodiments, the total capture device (640) produces sequestered emissions (622) that includes carbon dioxide. In preferred embodiments, the sequestered emissions (622) includes carbon dioxide and pollutants such as nitrogen oxides.
