Work package 6: Ocean alkalinization case studies

Leaders: Heriot-Watt University, University of Oxford

A common challenge in many negative emission proposals is the difficulty of creating new global industries and supply chains. Here we will investigate two case studies that examines realistic deployment scenarios for ocean alkalinization by augmenting existing infrastructure. This focus allows us to study the technical, social, environmental and economic consequences of modifying current industries to increase greenhouse gas removal, yet with implications that are relevant to the creation of new technologies. We propose a multi-disciplinary and reflexive approach to the development of the two case studies, centered on use of existing capacity in the cement and desalination industries.

Objectives

  1. Scopes and define realistic deployment scenarios for two ocean alkalinization approaches – ocean liming and electrochemical weathering
  2. Complete life cycle assessments of the scenarios based on international standards
