  2. Carbon dioxide generator - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_generator

    A carbon dioxide generator or CO 2 generator is a machine used to enhance carbon dioxide levels in order to promote plant growth in greenhouses or other enclosed areas. [1] [2] Carbon dioxide generators have been used to help grow marijuana. [3] [4] They can be fueled with propane or natural gas.

    "If carbon dioxide is so bad for the planet, why do greenhouse growers buy CO2 generators to double plant growth?" reads text above the image. The user captioned the post, "Science is hard. # ...

  4. CO2 fertilization effect - Wikipedia

    en.wikipedia.org/wiki/CO2_fertilization_effect

    Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems). [23]

  6. Bioenergy with carbon capture and storage - Wikipedia

    en.wikipedia.org/wiki/Bioenergy_with_carbon...

    Carbon flow schematic for different energy systems. The main appeal of BECCS is in its ability to result in negative emissions of CO 2. The capture of carbon dioxide from bioenergy sources effectively removes CO 2 from the atmosphere. [9] [10] Bioenergy is derived from biomass which is a renewable energy source and serves as a carbon sink ...

  7. Free-air concentration enrichment - Wikipedia

    en.wikipedia.org/wiki/Free-air_concentration...

    Increased atmospheric carbon dioxide has been found to reduce plant water use, and consequently, the uptake of nitrogen, so particularly benefiting crop yields in arid regions. [10] The carbohydrate content of crops is increased from photosynthesis, but protein content is reduced due to lower nitrogen uptake.

  8. Power-to-gas - Wikipedia

    en.wikipedia.org/wiki/Power-to-gas

    In the third method the carbon dioxide in the output of a wood gas generator or a biogas plant after the biogas upgrader is mixed with the produced hydrogen from the electrolyzer to produce methane. The free heat coming from the electrolyzer is used to cut heating costs in the biogas plant.

  9. Hydrogen-cooled turbo generator - Wikipedia

    en.wikipedia.org/.../Hydrogen-cooled_turbo_generator

    Carbon dioxide is favored as due to the very high density difference it easily displaces the hydrogen. The carbon dioxide is admitted to the bottom of the generator first, pushing the hydrogen out at the top. Then air is admitted to the top, pushing the carbon dioxide out at the bottom. Purging is best done with the generator stopped.
