Carbon capture and storage in China and implications for climate policy

PESD releases new working paper on the real drivers of carbon capture and storage in China and implications for climate policy


PESD researchers Richard Morse, Gang He, and Varun Rai offer a unique analysis of China's carbon capture and sequestration efforts, which are now widely viewed as critical for stabilization of the global climate. They argue that China's energy security interests are the primary drivers of current CCS projects. Contemplating CCS at scale in the Chinese context, they argue that Chinese energy markets present special obstacles for deploying CCS in China and offer insights into how international climate policy can engage this crucial problem.

The capture and permanent storage of CO2 emissions from coal combustion is now widely viewed as imperative for stabilization of the global climate.  Coal is the world’s fastest growing fossil fuel.  This trend presents a forceful case for the development and wide dissemination of technologies that can decouple coal consumption from CO2 emissions—the leading candidate technology to do this is carbon capture and storage (CCS). 

China simultaneously presents the most challenging and critical test for CCS deployment at scale.   While China has begun an handful of marquee CCS demonstration projects, the stark reality to be explored in this paper is that China’s incentives for keeping on the forefront of CCS technology learning do not translate into incentives to massively deploy CCS in power plant applications as CO2mitigation scenarios would have it.  In fact, fundamental and interrelated Chinese interests—in energy security, economic growth and development, and macroeconomic stability—directly argue against large-scale implementation of CCS in China unless such an implementation can be almost entirely supported by outside funding.  This paper considers how these core Chinese goals play out in the specific context of the country’s coal and power markets, and uses this analysis to draw conclusions about the path of CCS implementation in China’s energy sector. 

Finally, the paper argues that effective climate change policy will require both the vigorous promotion and careful calculation of CCS’s role in Chinese power generation.  As the world approaches the end of the Kyoto Protocol in 2012 and crafts a new policy architecture for a global climate deal, international offset policy and potential US offset standards need to create methodologies that directly address CCS funding at scale.  The more closely these policies are aligned with China’s own incentives and the unique context of its coal and power markets, the better chance they have of realizing the optimal role for CCS in global climate efforts.

后人有诗云:
秋高气爽桂花汀,云淡风轻碧空盈。
此生最幸恰逢君,前路漫漫携手行。

背景音乐之Miles away:

Madonna - Miles Away

I just woke up from a fuzzy dream
And I never want to see
the things that I have seen
I looked in the mirror and I saw your face
You looked back through me,
you were miles away.

All my dreams, they fade away
I'll never be the same
If you could see me the way you see yourself
And pretend to be someone else

You'll always love me more
Miles away
I hear it in your voice when we're
Miles away
You're not afraid to tell me
Miles away
I guess we're at our best when we're
Miles away

So far away
So far away
So far away
So far away
So far away
So far away
So far away
So far away

When no ones around and I have you here
I begin to see the picture it becomes so clear
You always have the biggest heart
when we're six thousand miles apart

Too much alone sound uncomfortable
silence can be so loud
Those three words are never enough
when it's long distance love...

You always love me more
miles away
I hear it in your voice when you're
miles away
You're not afraid to tell me
miles away
I guess we're at our best when we're
miles away

So far away so far away
So far away so far away
So far away so far away
So far away so far away

I'm alright
Don't be sorry
But it's true
When I'm gone..
You'll realize that I'm the best thing that happened to you...

You always love me more
miles away
I hear it in your voice when you're
miles away
You're not afraid to tell me
miles away
I guess we're at our best when we're
miles away

You always love me more
miles away
I hear it in your voice when you're
miles away
You're not afraid to tell me
miles away
I guess we're at our best when we're
miles away

So far away so far away
So far away so far away
So far away so far away
So far away so far away
So far away so far away
So far away so far away
So far away so far away
So far away so far away
So far away so far away

So far away so far away

碳捕获和碳储存(CCS)在中国的未来?

最近在思考的问题:中国到底要不要发展CCS,如何发展CCS?

Fact Sheet:
碳捕获和碳储存:简单说就是把直接排放到大气中的CO2捕集起来打到地下去,从而降低大气中的温室气体浓度。
中国(已经/或迟早将)成为最大温室气体排放国,2008年排放达68亿吨,占全球总排放的21.8%(BP能源统计)。
70%的能源依赖煤;80%的电力来自于煤;2001年到2008年,火电装机容量翻倍,从300GW到600GW(2008电力统计快报)。
要实现2℃目标(450ppm),2050年前,全球平均每年约需减排50-100亿吨(IPCC,IEA情景分析),其中14-19%要通过CCS来实现。
碳捕获的平均成本约为30美元/吨(保守估计),碳储存的平均成本为10美元/吨(乐观估计),储存潜力(远景)可达23000亿吨(PNNL)。全球CCS平均成本50-100美元/吨。
全球碳市场的价格,CER:15-30欧元/吨(点碳)。缺口30-60美元/吨。
2009年7月,全球第一个CCS示范项目大瀑布电力公司在德国北部的电厂捕获运行不错,碳储存阶段却因为地方居民的反对歇菜了(路透)。

争论焦点:
中国是否定量减排?减排多少?
CCS可以发挥多大作用?成本代价几何?
技术路线选择?未来前景?

正方观点:
以煤为主的能源结构决定了大量排放
中国受气候变化影响以及全球应对气候变化的国际压力增大
发电厂仍然是最大的温室气体来源
CCS技术已经基本成熟,在于国际机制的设计
Know-how(没找到好的翻译)以及潜在技术出口机遇

反方观点:
CCS技术还不成熟,不确定性仍然很大
CCS的成本非常大,除有EOR和ECBM外基本是烧钱
碳储存还未可知,中国地质条件非常复杂,不确定性较大
运输和储存过程中的风险,如泄漏等
中国尚无减排义务
CCS无溢出效应:不生产GDP,不解决就业
有这个钱干点啥不好:节能减排、可再生能源

被忽视的成本:
CCS的能源损失,约为20-23%,由此造成的煤炭使用增量将通过煤炭产业链条扩散到整个能源系统。
被忽视的事实:
煤电矛盾长期存在,电厂无法连煤炭成本都无法消化,哪能消化CCS增加的成本。

结论:
No easy CCS, No quick CCS.
能力建设(技术储备、地质调查、风险评价、公众参与)
主动CCS:对于符合中国能源战略的CCS技术和项目优先开展
被CCS:加强国际合作、学技术、引资金、搞创新
提高能效节能减排是王道,新能源可再生能源清洁能源是正道

欢迎讨论。

手冢不二之:给孩子们的教科书
引子
       话说手冢和不二在西葛西度过了快乐的夏天后(请参照前文《租赁协议》),手冢终于鼓起勇气求婚,不二看着Tiffany的钻戒,眨巴眨巴眼睛说:
       “好。”
       手冢乐得拉着不二的手,第二天就去见不二的爸妈。
       不二的爸爸很严肃,打量着手冢,问道:
       “手冢君是学什么专业的?”
       手冢毕恭毕敬地回答:“环保。”
       不二爸爸想了想,认真地说:“学环保好啊,不二从小就不太会收拾屋子,你正好可以……”
       多日后,不二鹦鹉学舌地把这事讲给同样学环境的大石和学国关的菊丸听,菊丸乐不可支,指着窗外一辆“保洁”车,对大石说,“大石,快看,你们院车!”
————背上不明之冤的分割线————
       再过了一段时间,手冢和不二决定搬到太平洋的另一边——加州湾区,因为手冢在那边找到了一份很环保的工作。两人也过上了男耕女织的生活。就这样,斗转星移,转眼已是第二年的春夏之交。
       有一天,不二接到同在湾区朋友的电话,去附近的一个地方BBQ。
       不二记下地址,在google map上搜了一下,离住的地方1个多小时的车程,叫Livermore。
       手冢凑过头来看了一眼,“哦,这里有很多好玩的。”
       “哦?”不二有点诧异地回头看看手冢,“有哪些好玩的?”
       手冢凝神屏气地细想了一会,认真地说:“有个国家实验室。”
————手冢君是学术男的分割线————
       话说这天手冢回家的时候,看到不二正在键盘上飞快的打字。
       手冢问:“亲爱的,干啥捏?”
       不二说:“国光桑,在写日记。”
       手冢定睛一看,《给孩子们的教科书》。
       手冢感动地:“不二,你真的开始考虑……”
       不二:“没,写着玩。”
       手冢定睛一看,好家伙,把我们的吵架记录地清清楚楚。
       不二(振振有辞):“为我们的孩子现身说教,让他们少走弯路。”
