Carbon capture and storage – why nickel alloys are capturing attention
As industries around the globe work to reduce emissions of carbon dioxide , there is also an effort to prevent its escape into the atmosphere by sequestering it . These technologies are known as carbon , capture and storage .

To help achieve the ambition of net zero anthropogenic greenhouse gas emissions , the Nickel Institute continues to explore what kind of contribution and criticality nickel will play in the successful deployment of carbon capture and storage ( CCS ). This is an endeavour that includes the entire CCS value chain from mature carbon capture , transportation to sub-surface storage .
Going for higher grades Corrosion and correct material selection are key concerns in the development of safe , reliable , and economical operation of CCS infrastructure . Many CCS processes involve low temperatures with free water present , resulting in acidic conditions and risk of corrosion . As such , carbon steel is not suitable and therefore
