Carbon dioxide mineralization using Newfoundland's ultramafic rocks

全球气温正在上升，部分原因是人为二氧化碳（CO2）排放。减少二氧化碳排放对于实现巴黎气候雅阁设定的目标是必要的。各国政府已经引入了总量管制和交易制度，并将碳税作为二氧化碳减排的激励措施，有效地使二氧化碳成为一种商品。因此，加拿大需要新的技术来消除大气中的二氧化碳，以保护我们的环境和经济。我们建议通过将其转化为长期储存的碳酸盐岩来研究从大气中去除CO2。这一过程被称为二氧化碳矿化，它已经在一些火成岩、蛇纹岩化地点和一些尾矿中自然发生。加拿大有许多地方有可能通过二氧化碳矿化来封存二氧化碳。 我们建议从加拿大纽芬兰省开始调查。纽芬兰拥有长期二氧化碳矿化所需的地质、地理和气候条件，包括超镁铁岩、地质稳定性、水资源以及潮湿多风的气候。本提案的目标是：1）调查岛屿蛇绿岩复合体湾和圣安东尼外的怀特丘陵内的CO2封存; 2）在实验室CO2矿化实验中使用这些地点的岩石样品，以确定通过CO2矿化快速封存CO2的反应和最佳条件。有关二氧化碳矿化的新知识将转移到参与碳总量管制和贸易的加拿大工业，或那些希望减少碳税支付额的人。

Global temperatures are rising, in part, due to anthropogenic carbon dioxide (CO2) emissions. CO2 reductions are necessary to meet the goals set by Paris Climate Accord. Governments have introduced cap and trade systems, and carbon taxation as CO2 reduction incentives, effectively making CO2 a commodity. Therefore, Canada needs new technologies to remove CO2 from the atmosphere for our environment and our economy. We propose to study the removal of CO2 from the atmosphere by converting it into long-term storage - carbonate rock. This process is known as CO2 mineralization and it already happens naturally in some igneous rocks, at sites of serpentinization, and in some mine tailings. Canada has many locations that have the potential to sequester CO2 through CO2 mineralization. We propose to start our investigations in the Canadian province of Newfoundland. Newfoundland has the geologic, geographic, and climatic conditions necessary for prolonged CO2 mineralization including ultramafic rocks, geologic stability, access to water, and a wet and windy climate. The objectives of this proposal are to 1) investigate CO2 sequestration within the Bay of Island Ophiolite Complex, and White Hills just outside of St. Anthony; 2) use rock samples from these sites in laboratory CO2 mineralization experiments to determine reactions and optimal conditions for rapid CO2 sequestration through CO2 mineralization. The new knowledge gained about CO2 mineralization will be transferrable to Canadian industry involved in carbon cap and trade or those wanting to reduce the amount they pay in carbon tax.******
