CCS - MV Bluefin 2017 V01 Methane

Project Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters.

A Contros model Hydro-C CH4 methane analyser was installed in the carbon team’s container and measured seawater from the ship’s auxiliary seawater pump for the duration of the voyage. The instrument had 2-2.5 litres per minute of seawater flowing over the sensor head with the entire housing submerged in seawater.

Survey settings:
The instrument was submerged in a bath of continuously flowing seawater with a flow of 2.5 litres per minute into the sensor head. Readings were recorded once per minute

Calibration Information:
The instrument was calibrated by the manufacturer in 2017.

项目概述：
为达成全球共识的二氧化碳（CO₂）减排目标，需配套一系列解决方案。碳捕获与封存（CCS）是助力降低澳大利亚能源体系向大气排放CO₂的技术体系之一。当前已有多种处于不同技术与商业化成熟度阶段的相关技术，且针对经济高效的CO₂捕获与封存技术的研发工作仍在持续推进。本研究将提供全新的知识支撑，为近海水域CCS项目的环境经济高效测量、监测与验证（MMV）提供决策依据。

研究团队将一台Contros Hydro-C CH4型甲烷分析仪安装于碳研究团队的集装箱内，在整个航行周期中，该仪器以船舶辅助海水泵抽取的海水作为检测样本开展测量。该仪器的传感器探头处海水流速为2~2.5升/分钟，且整机外壳完全浸没于海水中。

测量设置：
仪器浸没于持续流动的海水中，传感器探头处海水流速为2.5升/分钟，且每分钟记录一次测量数据。

校准信息：
该仪器于2017年由生产厂商完成校准。
