  "patent_number": "US 11648507",
  "country": "US",
  "title": "How to Capture Carbon Dioxide from Air or Smoke Using Seawater",
  "original_title": "Process and apparatus of ocean carbon capture and storage",
  "summary": "This patent describes a system that uses natural seawater to wash carbon dioxide out of industrial smoke or the air, then stores it safely in the ocean, aiming for an affordable, green way to fight climate change.",
  "what_it_does": "The patent details an apparatus and process for ocean carbon capture and storage. It involves a carbon capture device that scrubs gas containing carbon dioxide, like smoke from a power plant or even the atmosphere itself (Claim 1, 5, 6). Seawater is pumped into this device to absorb the carbon dioxide. This 'after-scrubbing seawater,' now containing dissolved CO2, is then discharged into the ocean's water column for storage (Claim 2). The system is designed to use low pumping energy, often referred to as 'low head,' and can be powered by renewable sources like wind or waves (Abstract, Claim 7, 10). For example, a coastal facility could pass its exhaust fumes through this system, using pumped seawater to clean the gas before releasing the CO2-enriched water into the sea.",
  "what_it_does_not_cover": [
    "Does not cover carbon capture methods that use chemical solvents or other non-seawater scrubbing agents.",
    "Does not cover storing captured carbon dioxide as a compressed gas, liquid, or solid, only dissolved in seawater within the ocean's water column.",
    "Does not cover systems requiring high-pressure pumps to move seawater for scrubbing, as it specifically emphasizes 'low head' operation (Claim 10).",
    "Does not cover land-based carbon capture systems that do not discharge the CO2-enriched seawater into the ocean (Claim 1).",
    "Does not cover systems that capture CO2 from sources other than directly from the atmosphere or fossil fuel flue gas (Claims 5, 6)."

  "abstract": "The present invention relates to a process and an apparatus of ocean carbon capture and storage (Ocean CCS), which can be used for carrying out carbon capture and storage of flue gas discharged from marine facilities using fossil energy such as coastal power plants and marine ships, and direct air capture (DAC). The natural engineering method are adopted in the present invention, and natural seawater is used for washing and dissolving CO2 gas for carbon capture; and natural seawater carbonate neutralization and formed bicarbonate is used for ocean storage in water column; and low head and large water flow is used to save energy. The discharged water complies with environmental regulations. The present invention provides an affordable and green effective mean for using marine ecosystems of carbon sinks and reservoirs to respond to the climate change.",
