UTILIZATION OF CARBON NEGATIVE RESOURCES TO REALIZE CARBON NEUTRAL PORTS

Abstract

 Carbon neutralization is a global issue that needs to be implemented immediately, but the use of energy resource is not fully explored. In this study, we examine the carbon negative resources that can be used in the coastal areas as a tool for realizing carbon neutral ports. Deterioration of coastal water environment is mainly due to long-term accumulation of enormous energy of organic carbon, thus energization of soil organic carbon in reduced sediments leads to improvement of carbon circulation. In addition, energization of soil organic carbon simultaneously reduces emissions of CO₂ and other greenhouse gases such as CH₄. In this paper, the potential of reduced coastal sediments as a negative carbon resource is quantified, and the electrochemical characteristics of soil organic matter in the electric fields are revealed experimentally.
