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
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.

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

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
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.
