Study on 2nd Generation Carbon Capture & Storage


REGINA, July 9, 2018 /CNW/ - Earlier today SaskPower announced their intention to retire their aging Boundary Dam Power Units #4 and #5, in 2021 and 2024 respectively. Despite this decision, the news release notes that Carbon Capture and Storage (CCS) will continue to play an active role in reducing emissions in Saskatchewan.

REGINA,2018年7月9日/ CNW / - 今天早些时候,SaskPower宣布他们打算分别在2021年和2024年撤掉老化的边界大坝动力装置#4和#5。 尽管做出了这一决定,但新闻稿指出,碳捕集与封存(CCS)将继续在减少萨斯喀彻温省的排放方面发挥积极作用。

In fact, the next generation of CCS technology will be significantly cheaper, more efficient, and integrate well with renewable energy - that's according to the preliminary results of a high-level CCS feasibility study on SaskPower's Shand Power Station. The study, conducted by the International CCS Knowledge Centre, presents a compelling business case for applying CCS technology to larger coal units.

事实上,新一代CCS技术将会更便宜,更高效,并与可再生能源完美整合 - 这是根据SaskPower的Shand电站的高水平CCS可行性研究的初步结果。 该研究由CCS国际知识中心进行,为将CCS技术应用于大型煤炭单位提供了令人信服的商业案例。

CCS has critical roles in providing reliable baseload power and mitigating greenhouse gas (GHGs) emissions. Once the feasibility study is complete, results will inform SaskPower of the potential to add CCS on Shand as part of the province's future energy mix. The International CCS Knowledge Centre will apply these principles to other feasibility and FEED studies throughout the world in a variety of industrial applications, including cement, waste-to-energy, as well as coal power.

CCS在提供可靠的基荷电力和减少温室气体(GHG)排放方面发挥着关键作用。 一旦可行性研究完成,结果将告知SaskPower有可能在Shand上添加CCS作为该省未来能源结构的一部分。 国际CCS知识中心将这些原则应用于世界各地的其他可行性和FEED研究,涉及各种工业应用,包括水泥,废物转化为能源以及煤电。

2nd Generation CCS


Recent advancements in engineering and design garnered from the feasibility study take large-scale carbon capture up to a new level, creating a second-generation in CCS.


The substantial experience gained from operating SaskPower's Boundary Dam Unit 3 Carbon Capture Facility (the world's first commercial-scale CCS project using post-combustion technology on a coal-fired power plant) is having positive impacts on the design contemplated in the feasibility study.  Scaling from a 150 MW coal-fired unit to 300 MW coal-fired unit, the new CCS design would have the potential to capture as much as 2 million tonnes of CO2 per year.

运行SaskPower边界大坝第3单元碳捕集设施(世界上第一个在燃煤电厂使用燃烧后技术的商业规模CCS项目)获得的丰富经验对可行性研究中设设想的设计产生了积极影响。 从一个150兆瓦的燃煤机组到300兆瓦的燃煤机组,新的CCS设计将有可能每年捕获高达200万吨的二氧化碳。

As with any second-generation technology, cost reductions are expected. Cost reductions for a next facility were originally anticipated to be 30% less; however, this study's preliminary findings indicate the potential for significantly deeper cost reductions.

与任何第二代技术一样,预计会降低成本。 原先预计下一个设施的成本降低30%; 然而,这项研究的初步调查结果表明,可以显着降低成本。

New CCS Design & Environment


There are also several important environmental benefits of the new design beyond CO2 abatement. The design takes advantage of the CCS plant's ability to vary the plant output, and to increase the capture rate at lower loads beyond 90%, such that it supports the integration of additional renewable energy from wind and solar.

除二氧化碳减排外,新设计还有一些重要的环境效益。 该设计利用了CCS工厂改变电厂产量的能力,并在低负荷下提高捕获率超过90%,从而支持风能和太阳能的额外可再生能源的整合。

The new design also requires no additional cooling water and eliminates all sulfur dioxide emissions.


Report Release


The CCS feasibility study on the Shand Power Station is due for publication release later this year.


In the meantime, for high-level information about the feasibility study, please see the abstracts for technical papers (spearheaded by the International CCS Knowledge Centre) that have been accepted to the renowned GHGT-14 - a biannual premier technical conference on CCS that attracts cutting edge experts from around the world to provide a platform for knowledge sharing and CCS growth.
