  electrochemical:
    text: electrochemical
    description: Uses electrochemistry to increase seawater alkalinity. This process
      typically involves separating seawater into acidic and alkaline streams, with
      the alkaline stream being released into the ocean to enhance carbon sequestration,
      with the acidic stream neutralized on land or used as a byproduct.
  mineral:
    text: mineral
    description: Involves adding alkaline minerals or particulate slurry (such as
      MgOH2, MgO, or CaO) to seawater either directly or through coastal outfalls
      (such as wastewater) to increase its alkalinity.
  dissolved:
    text: dissolved
    description: Involves the addition of dissolved or aqueous alkaline feedstocks
      (e.g. NaOH solution) into seawater either directly in coastal waters, through
      coastal outfalls or in the open ocean.
  river:
    text: river
    description: Involves adding alkaline substances (such as limestone) in rivers
      before they flow into the ocean for the purposes of carbon removal or emission
      reduction.
  coastal:
    text: coastal
    description: Introduces alkaline mineral sand (e.g. olivine), boulders or berms
      in coastal areas to promote the absorption of CO₂ from the atmosphere into carbonate
      minerals (e.g., calcium carbonate, CaCO₃).
  preequilibrated:
    text: preequilibrated
    description: Involves pre-treating seawater with alkalinity in a controlled setting,
      allowing equilibration with the atmosphere before returning into the marine
      system.
