Coal
Paragraphs

(Excerpt) According to climate scientists, averting the worst consequences of climate change requires that the increase in global temperature should be limited to 2°C (or 3.6°F). to achieve that objective, global emissions of green house gases (GHGs)—the main human cause of global warming—must be reduced to 50 percent of 1990 levels by 2050.

The key to successful climate change abatement at those scales lies in leveraging the collective actions of developed and developing countries. Cumulatively, developed countries have been responsible for most human emissions of GHGs. that picture will be quite different in the future as emissions from the developing world take over the top mantle. Given this dynamic, there is a general agreement internationally that developed countries will lead emissions reductions efforts and that developing countries will follow with “nationally ap- propriate mitigation actions.” turning that agreement into environmentally beneficial action requires close international coordination between the developed and developing countries in allocating the responsibility for the necessary reductions and following up with credible actions. However, the instruments employed so far to promote the necessary collective action have proved to be insufficient, unscalable, and questionable in terms of environmental benefit and economic efficiency.

Currently, the most important and visible link be- tween developed and developing countries’ efforts on climate change is the Clean development Mechanism (CdM). the CdM uses market mechanisms—the “carbon markets”—to direct funding from developed countries to those projects in developing countries that lead to reductions in emissions of warming gases. In reality, the experience with the CdM has been mixed at best since its inception in 2006. while the CdM has successfully channeled funding to many worthy projects that reduce emissions of warming gasses, it has also spawned myriad projects with little environmental benefits. overall, the CdM has led to a significant overpayment by developed countries for largely dubious emissions reductions in developing countries.

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 CO2 mitigation 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.

PESD affiliated faculty Burton Richter argues in Roll Call that the climate bill passed by the US House of Representatives misses the mark on several fronts, especially in its inadequate funding for long-term research. The Senate must do better.

Will climate change finally wake us from our energy lethargy? Three times in the past 36 years, our nation has suffered from oil shocks and done little to implement lasting policies that could avoid them in the future. We took some small steps in the 1970s and 1990s, but ultimately we failed to close the deal.

Today, we are more dependent than ever on imported oil - two-thirds of our total consumption in 2008 came from other nations compared to one-third in 1973. And today we face the recognized threat of climate change, which will affect the entire world dramatically in the coming decades - unless we and other nations reduce the production of greenhouse gases, primarily carbon dioxide.

For our oil dependence, we took half-measures. Will we do better on climate change? The House version of the climate bill, which passed by a narrow margin, offers some hope, but it misses the mark on several accounts. To satisfy various interests - some legitimate, others selfish - drafters of the legislation compromised away a number of crucial provisions. The big question now: Will the Senate make it better or worse?

The House gives away too many of the emission allowances that are central to cap-and-trade; places too much emphasis on renewables, which are not as ready for the big time as their advocates claim; gives too little emphasis to natural gas and nuclear power, both of which could play a large role in replacing coal; does not fund the necessary long-term research, development and demonstration program that President Barack Obama proposed; and places far too little emphasis on energy efficiency, which is easy to implement and saves money in the long run.

The Senate can do better. It should start by including in the legislation the president's Clean Energy Technology Fund, an investment of $15 billion per year over 10 years to develop affordable, low-emission energy technologies that could be used by the developing world as well as by rich countries. The provision wasn't included in the House bill, and I am one of 34 Nobel Laureates who recently wrote to the president, urging him to try to get Congress to include the fund in a final climate bill.

A stable funding mechanism for basic and applied research, development and demonstration is critical to developing the technologies we will need to greatly cut emissions in a cost-effective manner. The Senate should set aside at least 5 percent of all emission allowances for the Clean Energy Technology Fund, and for purposes of stability of funding, provide support for the full lifetime cost of a competitively selected project at the time the award is made.

Current technologies are a good start, but they are not up to doing the entire job. For example, we have no effective way to store energy from intermittent sources to smooth out the variations of wind and solar output that hugely complicate their use on a large scale.

Another challenge is the use of hydrogen fuel cells to store energy from intermittent sources and use it for transportation. The present cells use so much platinum as a catalyst that the entire yearly world supply of platinum is not enough to supply the fuel cells needed for U.S. auto production, much less the world's.

Our very expensive corn ethanol program is at best a marginal reducer of emissions, and if the effects of land-use changes are included, is positively harmful. There are more advanced biofuels that might actually do some good, but they, too, need more research and a lot more development and demonstration.

Nuclear power, a safe source available 24/7, is being slowed by concern about the lack of a permanent repository for spent nuclear fuel. There is no intermediate-term problem because spent fuel can be stored safely at reactor sites for many years. In the interim, we can do the research and development that might allow us to reduce the volume of waste in a way that is proliferation-resistant.

Energy efficiency is an easy, low-cost way to reduce emissions. There are many ways to improve efficiency in power generation, transportation and buildings that would benefit from the president's fund. Some things don't even need research and development, like an energy audit before the sale of any building that would tell the buyer how to save with simple upgrades that pay for themselves through reduced utility bills. Unfortunately, the House failed to include a provision for the audits, bowing to the National Association of Realtors, which seems to want buyers to know as little as possible.

Tackling climate change is not mission impossible. Deploying today's technologies and supporting the research and development for tomorrow's will put us on the right path toward achieving energy security and mitigating climate change.

Paragraphs

Project development is particularly challenging in “frontier” environments where alternative technologies, conflicting laws and agencies, and uncertain benefits or risks constrain the knowledge or decisions of participants.  Carbon capture and storage (“CCS”) projects by means of geologic sequestration are pursued in such an environment.  In these circumstances, entrepreneurs can seek to employ two distinct types of tools:  the game-changer, being an improvement to the status quo for all those similarly situated, generally achieved through collective or governmental action; and the finesse, being an individualized pursuit of an extraordinary project that is minimally affected by a given legal, business or technological obstacle.  These techniques are illustrated in the case of CCS as to ownership of property rights, carbon dioxide (“CO2”) transportation economics, liability for stored CO2 following the closure of injection wells, inter-agency and federal-state conflicts, competing technologies, and uncertain economic or legal incentives.  The finesse and the game-changer should also be useful concepts for creative solutions in other applications.

Coal is the major primary energy which fuels economic growth in China. The original Soviet-style institutions of the coal sector were adopted after the People's Republic of China was founded in 1949. But since the end of 1970s there have been major changes: a market system was introduced to the coal sector and the Major State Coalmines were transferred from central to local governments. This paper explains these market-oriented and decentralizing trends and explores their implications for the electric power sector, now the largest single consumer of coal.

The argument of this paper is that the market-oriented and decentralizing reforms in the coal sector were influenced by the changes in state energy investment priority as well as the relationship between the central and local governments in the context of broader reforms within China’s economy. However, these market-oriented and decentralizing reforms have not equally influenced the electric power sector. Since coal is the primary input into Chinese power generation, and power sector reform falls behind coal sector reform, the tension between the power and coal sectors is unavoidable and has raised concerns about electricity shortages.

This paper analyzes the potential contribution of carbon capture and storage (CCS) technologies to greenhouse gas emissions reductions in the U.S. electricity sector.  Focusing on capture systems for coal-fired power plants until 2030, a sensitivity analysis of key CCS parameters is performed to gain insight into the role that CCS can play in future mitigation scenarios and to explore implications of large-scale CCS deployment.  By integrating important parameters for CCS technologies into a carbon-abatement model similar to the EPRI Prism analysis (EPRI, 2007), this study concludes that the start time and rate of technology diffusion are important in determining the emissions reduction potential and fuel consumption for CCS technologies. 

Comparisons with legislative emissions targets illustrate that CCS alone is very unlikely to meet reduction targets for the electric-power sector, even under aggressive deployment scenarios.  A portfolio of supply and demand side strategies will be needed to reach emissions objectives, especially in the near term.  Furthermore, the breakdown of capture technologies (i.e., pre-combustion, post-combustion, and oxy-fuel units) and the level of CCS retrofits at pulverized coal plants also have large effects on the extent of greenhouse gas emissions reductions.
