Carbon dioxide in water nanoemulsions for carbon sequestration

该项目将通过消除长期泄漏到饮用水含水层或大气的风险，解决对地质二氧化碳(CO2)封存的一个关键反对意见。通过注入水中二氧化碳的纳米乳状液，该项目寻求在几周内显示对永久稳定的固体碳酸盐的完全反应，从而消除对安全盖层或延长密封完整性监测的需要。将使用创新方法产生新的知识，以创造和稳定水中二氧化碳纳米乳液，并展示二氧化碳快速转化为稳定的矿物。在开放潜在的封存目标以包括没有安全上限的地区、降低成本和消除长期泄漏风险方面，好处是显著的

The project will address a key objection to geological carbon dioxide (CO2) sequestration by removing the risk of long-term leakage to drinking water aquifers or to atmosphere. By injecting a nano-emulsion of CO2-in-water, the project seeks to show complete reaction to permanently stable solid carbonate occurs within weeks, eliminating the need for secure caprock or extended seal integrity monitoring. New knowledge will be generated using innovative approaches to create and stabilise CO2-in-water nano-emulsions and demonstrate the fast conversion of CO2 into stable minerals. The benefits are significant in opening potential sequestration targets to include areas without secure caps, reduced cost and elimination of long-term leakage risk
