船舶によるCO₂シャトル輸送のCCSへの適用に関する予備FS

1st August 2014

Organisation(s): Chiyoda, Global CCS Institute

Topic(s): Carbon capture, CO₂ transport, Use and storage (CCUS)

提案する船舶によるCO₂の輸送では、Fig 1.2-1に示す通り、液体CO₂（LCO₂）のカーゴタンクを備えた船が重要な構成要素となる。すなわちこのシステムでは、圧縮CO₂を直接船から圧入坑井の海底坑口に送る船上圧入ポンプを特徴としている。
本提案に基づく船舶を使用したシャトル輸送により、複数の回収サイトから複数の貯留サイトへのCCSチェーンの接続が可能となる。これには、以下のような利点がある。

CCS導入初期の「シンク（吸収源）-ソース（排出源）マッチング」要件の緩和
水中にあるCO₂輸送パイプを通じた、海底下地層への直接アクセス
積み出し港と注入サイトの両方に、大容量の一時貯留タンクを設置する必要がない
CCSプロジェクト計画を柔軟に変更できる
注入サイト設備を簡単に廃止、移転、再利用できる
従って、システムの冗長性を確保できる

Preliminary feasibility study on CO2 carrier for ship-based CCS. Phase 2: unmanned offshore facility

Preliminary feasibility study on CO₂ carrier for ship-based CCS. Phase 2: unmanned offshore facility

30th November 2012

Organisation(s): Chiyoda, Global CCS Institute

Topic(s): Carbon capture, CO₂ transport, Use and storage (CCUS)

The current study considers the transport of CO₂ using shuttle ships. It follows on from an earlier study completed by Chiyoda Corporation. In this study, the CO₂ is stored and transported at different conditions and the injection site has been relocated meaning that different ocean conditions need to be considered. The viability of an unmanned injection buoy, instead of a platform, was also considered in this study. The impact of the changes to the CO₂ conditions and the injection site on the tank and ship design, the loading and unloading equipment and the flexible riser pipe is studied in this report. An economic evaluation is also completed to assess the cost of CO₂ transport for a nominal injection volume of 1 million tonnes per year with the transport distance ranging from 200 to 1,600 km. The shuttle ship’s capacity is approximately 3,000 tonnes CO₂ and to reach the nominal injection volume requires a shuttle ship to inject its cargo on a daily basis.

This report presents how the storage capacity of CO₂ in the offshore area beyond the continental shelf ( i.e.deeper than 200m below sea-level) can be assessed. The “volumetric method” as used for identifying onshore storage capacity was adapted for estimating the capacity in offshore locations.

31st October 2011

Organisation(s): Chiyoda, Global CCS Institute

Topic(s): Carbon capture, CO₂ transport, Use and storage (CCUS)

This report from Chiyoda Corporation covers a technical pre-feasibility study of shuttle type CO₂ ship transport, the engineering design of ship equipment and injection method suitable for offshore operations, and goes further on to discuss the regulatory considerations for ship-based CO₂ transport and injection.

Many regions will be unable to secure suitable onshore CO₂ storage and that this will be the major barrier to the deployment of domestic CCS. Shipping CO₂ to a suitable offshore site via smaller shuttle tanks could provide an economical alternative to long distance seabed pipeline transportation.

The Project Leader for the study is Professor Masahiko Ozaki, who was the lead author on the IPCC Special Report on CCS -Chapter on CO₂ Shipping Transportation.

선박 기반 CCS의 CO₂ 수송선 관련 예비 타당성 연구

1st October 2011

Organisation(s): Chiyoda, Global CCS Institute

Topic(s): Carbon capture, CO₂ transport, Use and storage (CCUS)

본 보고서는 치요다社의 CO₂ 수송선 기술 관련 예비 타당성 연구에 대해 다루며, 해양지중 운영에 있어서 선박 설비의 엔지니어링 설계 및 주입 방식, 더 나아가 CO₂ 수송선 및 주입에 관한 규제와 고려사항에 대해 논의한다. 육상 부지에 대한 CO₂ 저장의 적합성을 보장하기 어렵다는 점은 일본 내 CCS 보급에 있어서 주요 장벽이 될 것이다. 보다 작은 규모의 셔틀 탱크를 이용하여 CO₂를 적합한 해양지중 부지로 선박 수송하는 방식은 장거리 해저 파이프라인 수송에 대한 경제적 대안이 될 수 있다.
