PCC Pilot Plant Test: Continuous Operation Results


<Background> Zero‐carbon power plants, as well as drastic energy‐saving and maximum use of renewable energy, are essential

to reduce GHG emissions by 80% by 2050. Major emission sources that keep releasing large amounts of CO2 during their long lifetime, especially coal‐fired

power plants, etc., are recommended to implement CCS. To introduce CCS, environmental conservation should be considered by taking Japan‐specific factors into

account: for example, major emission sources spreading throughout Japan, highly‐developed coastal areas, etc.

<Purpose> Examining the components and whole system of the shuttle ship transportation and injection concept, which is

seen as a feasible technology to efficiently transport CO2 between onshore emission sources and offshore storage sites.

Examining environmental impacts of amine solutions that are used to separate and capture CO2. Investigating the effective introduction of CCS (public acceptance, economic evaluation, etc.)

<Goal>Integrated CCS demonstration project consisting of CO2 separation and capture at emission sources such as coal‐fired power plants, CO2 transportation via a shuttle ship, injection from the ship to under the seabed, and monitoring.

Ministry of the Environment CCS Project


Task 2. Study of Shuttle Ship Transportation and Injection System• Study of shipping models and schedules.• Preliminary design of a vessel and its components.• Technical studies of the components and whole system of

transportation and injection, etc.

Task 3. Investigation of an Effective Introduction• Summarization of advantages and challenges of an environmentally friendly CCS.• Feasibility study and supporting policy evaluation.• Review of Strategy to enhance public acceptance and build consensus.• Exploration of overseas deployment, etc.

MoE CCS Project – Institutional Arrangement


<Details>① Understanding environmental load of CO2 capture processUnderstanding the actual status of environmental effects of amine solutionsduring the use phase and the disposal phase will be conducted.

② Evaluation of amine emissionsQuantitative analysis of amine compounds in emission tests under continuousoperation of Mikawa Post Combustion Capture Pilot Plant will be carried out.

③ Assessing environmental riskTaking into account the results of ①,②, and ④, we will determine thechemical substances subject to risk assessment, define the scope of theassessment, and conduct risk assessments.

④ Investigation of methods to mitigate amine emissionsUsing the newly constructed system which enables control of amine emissionto a low level, optimum operation parameters will be investigated andmitigation performance of the amine emissions will be confirmed to studyemission reduction methods.

⑤ Drafting guidelinesTo minimize environmental impacts of the CO2 capture process, and toencourage plant owners to construct and install the equipment appropriately,we will draft guidelines, which will include guideline values for environmentalrisk assessment.

⑥ Front‐end design for CO2 capture demonstration projectIn order to construct and execute the demonstration facility after FY2016, front‐end design of a CO2 capture facility, with the capacity to capture around 1000 tons of CO2 per day or more, will be performed.

<Background and goals> CO2 absorbents (amine solutions) may affect the

environment when released into the atmosphere. Nitrosamine, a class of chemical compounds including

some amine derivatives, may pose risks to human health. To draft guidelines for risk assessment, which include

guideline values, by understanding the environmentalload through the assessment of risks of the CO2 captureprocess.

To study the impact of emissions from amine solutions onthe environment and flue gas composition, and emissionreduction technologies.

Toshiba continues to work in improving the efficiency anddecarbonizing thermal power plant, as an integrated powerplant supplier.

Toshiba recognizes CCS as means to fundamentally decreasethe CO2 emission of the thermal power plants. With this view,Toshiba built its pilot plant at Mikawa power plant in 2009 totest, verify and accelerate the early deployment of the technology.

Mikawa pilot plant will be used to support the CCS Project forthe Ministry of the Environment, the goal of which is to realizea fully integrated CCS demonstration in Japan, from CO2 capture,transport, off-shore sub-seabed storage and monitoring.
