  • Another Tipping Point: US Coal Supply Decline So Real Even West Virginia Concurs (REPORT)

    November 26, 2013 (Huffington Post via NewEnergyNews)

    Everywhere we turn, environmental news is filled with horrid developments and glimpses of irreversible tipping points.

    Just a handful of examples are breathtaking: Scientists have dared to pinpoint the years at which locations around the world may reach runaway heat, and in the northern hemisphere it's well in sight for our children: 2047. Survivors of Superstorm Sandy are packing up as costs of repair and insurance go out of reach, one threat that climate science has long predicted. Or we could simply talk about the plight of bees and the potential impact on food supplies. Surprising no one who explores the Pacific Ocean, sailor Ivan MacFadyen described long a journey dubbed The Ocean is Broken, in which he saw vast expanses of trash and almost no wildlife save for a whale struggling a with giant tumor on its head, evoking the tons of radioactive water coming daily from Fukushima's lamed nuclear power center. Rampaging fishing methods and ocean acidification are now reported as causing the overpopulation of jellyfish that have jammed the intakes of nuclear plants around the world. Yet the shutting down of nuclear plants is a trifling setback compared with the doom that can result in coming days at Fukushima in the delicate job to extract bent and spent fuel rods from a ruined storage tank, a project dubbed "radioactive pick up sticks."

    With all these horrors to ponder you wouldn't expect to hear that you should also worry about the United States running out of coal. But you would be wrong, says Leslie Glustrom, founder and research director for Clean Energy Action. Her contention is that we've passed the peak in our nation's legendary supply of coal that powers over one-third of our grid capacity. This grim news is faithfully spelled out in three reports, with the complete story told in Warning: Faulty Reporting of US Coal Reserves (pdf). (Disclosure: I serve on CEA's board and have known the author for years.)

    Glustrom's research presents a sea change in how we should understand our energy challenges, or experience grim consequences. It's not only about toxic and heat-trapping emissions anymore; it's also about having enough energy generation to run big cities and regions that now rely on coal. Glustrom worries openly about how commerce will go on in many regions in 2025 if they don't plan their energy futures right.

    Scrutinizing data for prices on delivered coal nationwide, Glustrom's new report establishes that coal's price has risen nearly 8 percent annually for eight years, roughly doubling, due mostly to thinner, deeper coal seams plus costlier diesel transport expenses. Higher coal prices in a time of "cheap" natural gas and affordable renewables means coal companies are lamed by low or no profits, as they hold debt levels that dwarf their market value and carry very high interest rates.

    One leading coal company, Patriot, filed for bankruptcy last year; many others are also struggling under bankruptcy watch and not eager to upgrade equipment for the tougher mining ahead. Add to this the bizarre event this fall of a coal lease failing to sell in Wyoming's Powder River Basin, the "Fort Knox" of the nation's coal supply, with some pundits agreeing this portends a tightening of the nation's coal supply, not to mention the array of researchers cited in the report. Indeed, at the mid point of 2013, only 488 millions tons of coal were produced in the U.S.; unless a major catch up happens by year-end, 2013 may be as low in production as 1993.

    Coal may exist in large quantities geologically, but economically, it's getting out of reach, as confirmed by US Geological Survey in studies indicating that less than 20 percent of US coal formations are economically recoverable, as explored in the CEA report. To Glustrom, that number plus others translate to 10 to 20 years more of burning coal in the US. It takes capital, accessible coal with good heat content and favorable market conditions to assure that mining companies will stay in business. She has observed a classic disconnect between camps of professionals in which geologists tend to assume money is "infinite" and financial analysts tend to assume that available coal is "infinite." Both biases are faulty and together they court disaster, and "it is only by combining thoughtful estimates of available coal and available money that our country can come to a realistic estimate of the amount of US coal that can be mined at a profit." This brings us back to her main and rather simple point: "If the companies cannot make a profit by mining coal they won't be mining for long."

    No one is more emphatic than Glustrom herself that she cannot predict the future, but she presents trend lines that are robust and confirmed assertively by the editorial board at West Virginia Gazette:

    Although Clean Energy Action is a "green" nonprofit opposed to fossil fuels, this study contains many hard economic facts. As we've said before, West Virginia's leaders should lower their protests about pollution controls, and instead launch intelligent planning for the profound shift that is occurring in the Mountain State's economy.

    The report "Warning, Faulty Reporting of US Coal Reserves" and its companion reports belong in the hands of energy and climate policy makers, investors, bankers, and rate payer watchdog groups, so that states can plan for, rather than react to, a future with sea change risk factors.

    [Clean Energy Action is fundraising to support the dissemination of this report through December 11. Contribute here.]

    It bears mentioning that even China is enacting a "peak coal" mentality, with Shanghai declaring that it will completely ban coal burning in 2017 with intent to close down hundreds of coal burning boilers and industrial furnaces, or shifting them to clean energy by 2015. And Citi Research, in "The Unimaginable: Peak Coal in China," took a look at all forms of energy production in China and figured that demand for coal will flatten or peak by 2020 and those "coal exporting countries that have been counting on strong future coal demand could be most at risk." Include US coal producers in that group of exporters.

    Our world is undergoing many sorts of change and upheaval. We in the industrialized world have spent about a century dismissing ocean trash, overfishing, pesticides, nuclear hazard, and oil and coal burning with a shrug of, "Hey it's fine, nature can manage it." Now we're surrounded by impacts of industrial-grade consumption, including depletion of critical resources and tipping points of many kinds. It is not enough to think of only ourselves and plan for strictly our own survival or convenience. The threat to animals everywhere, indeed to whole systems of the living, is the grief-filled backdrop of our times. It's "all hands on deck" at this point of human voyaging, and in our nation's capital, we certainly don't have that. Towns, states and regions need to plan fiercely and follow through. And a fine example is Boulder Colorado's recent victory to keep on track for clean energy by separating from its electric utility that makes 59 percent of its power from coal.

    Clean Energy Action is disseminating "Warning: Faulty Reporting of US Coal Reserves" for free to all manner of relevant professionals who should be concerned about long range trends which now include the supply risks of coal, and is supporting that outreach through a fundraising campaign.

    TODAY’S STUDY: THE STATE OF NUCLEAR (EXPENSIVE)

    Technology is always promising. The problem is that when it delivers, there is a fee-for-service. The new versions of the Old Energies (advanced nuclear, "clean" coal) are seductively promising but remain largely unproven for the simple reason that testing them is too costly. Moving ahead on them would be even more expensive and - given the risks of handling radioactive waste or huge amounts of carbon dioxide - would represent an unwise degree of potential public harm. And building even a small capacity would take decades.

    Meanwhile, the New Energies (especially onshore wind and rooftop solar) become more affordable and more accessible. As to risk, there IS the ocassional turbine failure or injury installing rooftop panels. Not exactly financial catastrophes or environmental disasters, are they?


    The Future of the Nuclear Fuel Cycle; An interdisciplinary MIT study
    Mujid Kazimi, Ernest J. Moniz and Charkes W. Forsberg, September 2010 (Massachusetts Institute of Technology)

    Study Context

    In 2003 MIT published the interdisciplinary study The Future of Nuclear Power. The underlying motivation was that nuclear energy, which today provides about 70% of the “zero”- carbon electricity in the U.S., is an important option for the market place in a low-carbon world. Since that report, major changes in the US and the world have taken place as described in our 2009 Update of the 2003 Future of Nuclear Power Report.

    Concerns about climate change have risen: many countries have adopted restrictions on greenhouse gas emissions to the atmosphere, and the U.S. is expected to adopt similar limits. Projections for nuclear-power growth worldwide have increased dramatically and construction of new plants has accelerated, particularly in China and India. This study on The Future of the Nuclear Fuel Cycle has been carried out because of the continuing importance of nuclear power as a low-carbon option that could be deployed at a scale that is material for mitigating climate change risk, namely, global deployment at the Terawatt scale by mid-century. To enable an expansion of nuclear power, it must overcome critical challenges in cost, waste disposal, and proliferation concerns while maintaining its currently excellent safety and reliability record. In the relatively near term, important decisions may be taken with far reaching long-term implications about the evolution of the nuclear fuel cycle—what type of fuel is used, what types of reactors, what happens to irradiated fuel, and what method of disposal for long term nuclear wastes. This study aims to inform those decisions. For decades, the discussion about future nuclear fuel cycles has been dominated by the expectation that a closed fuel cycle based on plutonium startup of fast reactors would eventually be deployed. However, this expectation is rooted in an out-of-date understanding about uranium scarcity. Our reexamination of fuel cycles suggests that there are many more viable fuel cycle options and that the optimum choice among them faces great uncertainty—some economic, such as the cost of advanced reactors, some technical such as implications for waste management, and some societal, such as the scale of nuclear power deployment and the management of nuclear proliferation risks. Greater clarity should emerge over the next few decades, assuming that the needed research is carried out for technological alternatives and that the global response to climate change risk mitigation comes together. A key message from our work is that we can and should preserve our options for fuel cycle choices by continuing with the open fuel cycle, implementing a system for managed LWR spent fuel storage, developing a geological repository, and researching technology alternatives appropriate to a range of nuclear energy futures.

    Study Findings and Recommendations

    Economics

    The viability of nuclear power as a significant energy option for the future depends critically on its economics. While the cost of operating nuclear plants is low, the capital cost of the plants themselves is high. This is currently amplified by the higher cost of financing construction due to the perceived financial risk of building new nuclear plants.

    For new base load power in the US, nuclear power plants are likely to have higher levelized electricity costs than new coal plants (without carbon dioxide capture and sequestration) or new natural gas plants. Eliminating this financial risk premium makes nuclear power levelized electricity cost competitive with that of coal, and it becomes lower than that of coal when a modest price on carbon dioxide emissions is imposed. This is also true for comparisons with natural gas at fuel prices characteristic of most of the past decade. Based on this analysis, we recommended in 2003 that financial incentives be provided for the first group of new nuclear plants that are built. The first mover incentives put in place in the US since 2005 have been implemented very slowly.

    Recommendation: Implementation of the first mover program of incentives should be accelerated for the purposes of demonstrating the costs of building new nuclear power plants in the U.S. under current conditions and, with good performance, eliminating the financial risk premium. This incentive program should not be extended beyond the first movers (first 7–10 plants) since we believe that nuclear energy should be able to compete on the open market as should other energy options.

    Fuel Cycle

    There is no shortage of uranium resources that might constrain future commitments to build new nuclear plants for much of this century at least. The benefits to resource extension and to waste management of limited recycling in LWRs using mixed oxide fuel as is being done in some countries are minimal. Scientifically sound methods exist to manage spent nuclear fuel.

    Recommendation For the next several decades, a once through fuel cycle using light water reactors (LWRs) is the preferred economic option for the U.S. and is likely to be the dominant feature of the nuclear energy system in the U.S. and elsewhere for much of this century. Improvements in light-water reactor designs to increase the efficiency of fuel resource utilization and reduce the cost of future reactor plants should be a principal research and development focus.

    Spent Nuclear Fuel Management

    Long term managed storage preserves future options for spent fuel utilization at little relative cost. Maintaining options is important because the resolution of major uncertainties over time (trajectory of US nuclear power deployment, availability and cost of new reactor and fuel cycle technologies) will determine whether LWR spent nuclear fuel is to be considered a waste destined for direct geological disposal or a valuable fuel resource for a future closed fuel cycle. Preservation of options for future fuel cycle choices has been undervalued in the debate about fuel cycle policy. Managed storage can be done safely at operating reactor sites, centralized storage facilities, or geological repositories designed for retrievability (an alternative form of centralized storage).

    Recommendations: Planning for long term managed storage of spent nuclear fuel—for about a century—should be an integral part of nuclear fuel cycle design. While managed storage is believed to be safe for these periods, an R&D program should be devoted to confirm and extend the safe storage and transport period. The possibility of storage for a century, which is longer than the anticipated operating lifetimes of nuclear reactors, suggests that the U.S. should move toward centralized SNF storage sites—starting with SNF from decommissioned reactor sites and in support of a long-term SNF management strategy. This will have the additional benefits of resolving federal liability for its failure to start moving SNF from reactor sites starting in 1998.

    Waste Management

    Permanent geological isolation will be required for at least some long-lived components of spent nuclear fuel, and so systematic development of a geological repository needs to be undertaken. The conclusion of the 2003 MIT report that the science underpinning long term geological isolation is sound remains valid. The siting of a geological repository for spent nuclear fuel and high-level waste has been a major challenge for the United States. The failures and successes of U.S. and European programs suggest that a nuclear waste management organization should have the following characteristics: (1) authority for site selection in partnership with state and local governments, (2) management authority for nuclear waste disposal funds, (3) authority to negotiate with facility owners about SNF and waste removal, (4) engagement with policy makers and regulators on fuel cycle choices that affect the nature of radioactive waste streams, and (5) long-term continuity in management. These characteristics are not recognizable in the U.S. program to date. A key element of successful waste management programs is consistency of science based decisions.

    Recommendation: We recommend that a new quasi-government waste management organization be established to implement the nation’s waste management program. Closed fuel cycle design has focused on what goes back to the reactor but not on how wastes are managed.

    Recommendation: We recommend (1) the integration of waste management with the design of the fuel cycle, and (2) a supporting R&D program in waste management to enable full coupling of fuel cycle and waste management decisions. A key finding is that the U.S. classifies many radioactive wastes by source rather than by hazard. This has already created gaps in disposal pathways for wastes and this problem will be exacerbated with alternative fuel cycles.

    Recommendation: We recommend that an integrated risk-informed waste management system be adopted that classifies all wastes according to their composition and defines disposal pathways according to risk.

    Future Nuclear Fuel Cycles

    The choices of nuclear fuel cycle (open, closed, or partially closed through limited SNF recycle) depend upon (1) the technologies we develop and (2) societal weighting of goals (safety, economics, waste management, and nonproliferation). Once choices are made, they will have major and very long term impacts on nuclear power development. Today we do not have sufficient knowledge to make informed choices for the best cycles and associated technologies. Our analysis of alternative fuel cycles for nuclear power growth scenarios through 2100 yields several results of direct importance in fuel cycle choices:

    a-fuel cycle transitions take 50 to 100 years;there is little difference in the total transuranic inventories or uranium needs in this century

    b-for the standard plutonium-initiated closed fuel cycle, many LWRs are needed in this century for nuclear power growth scenarios. A key finding is that reactors with very high conversion ratios (fissile material produced divided by fissile material in the initial core) are not required for sustainable closed fuel cycles that enable full utilization of uranium and thorium resources.

    A conversion ratio near unity is acceptable and opens up alternative fuel cycle pathways such as:
    a-Very different reactor choices. such as hard-spectrum LWRs rather than traditional fast reactors for closed fuel cycles, with important policy implications and potentially lower costs.
    b-Startup of fast reactors with low-enriched uranium rather than high-enriched uranium or plutonium thereby eliminating the need for reprocessing LWR SNF for closed fuel cycle startup.

    There is adequate time before any choices for deployment need to be made to move away from the open fuel cycle. However, there are many viable technological choices that need to be examined, and the time needed to establish new commercial options in the nuclear power business is long. Consequently, the R&D needed should now be vigorously pursued to enable alternative fuel cycle options by mid-century.

    Recommendation: Integrated system studies and experiments on innovative reactor and fuel cycle options should be undertaken with vigor in the next several years to determine the viable technical options, define the timelines of when decisions need to be made, and select a limited set of options as the basis for the path forward.

    Nonproliferation

    Proliferation at its center is an institutional challenge. The civilian nuclear power fuel cycle is one of several routes to nuclear weapons materials. Establishment of enrichment and/or reprocessing capabilities are proliferation concerns and are not economic choices for small reactor programs. However, guaranteed supplies of fuel are important to countries that embark on electricity production from nuclear energy. Waste management will be a significant challenge for many countries.

    Recommendation: The US and other nuclear supplier group countries should actively pursue fuel leasing options for countries with small nuclear programs, providing financial incentives for forgoing enrichment, technology cooperation for advanced reactors, spent fuel take back within the supplier’s domestic framework for managing spent fuel, and the option for a fixed term renewable commitment to fuel leasing (perhaps ten years).

    Research Development and Demonstration

    Many decades are needed to research, develop, demonstrate, license, and deploy at scale any major new nuclear technology. A robust RD&D program, aligned with the possibility of substantial nuclear power growth, must be implemented if the U.S. is to have well-developed fuel cycle options in time to make wise strategic fuel cycle choices. The 2010 DOE roadmap is a significant improvement on previous agency plans

    Recommendations for RD&D Priorities:

    a-Enhanced LWR performance and fuels.
    b-A much broader set of spent fuel storage and nuclear waste disposal options than has been pursued for decades.
    c-Modeling and simulation capability for developing technology options and for understanding tradeoffs among options.
    d-Innovative nuclear energy applications and concepts, including provision of process heat to industrial applications and development of modular reactors.
    e-Rebuilding the supporting R&D infrastructure, such as materials test facilities and other key facilities to enable innovative fuel cycle and reactor R&D. We estimate that about $1 B/year is appropriate for supporting the R&D and infrastructure programs. Additional funding will be needed for large-scale government-industry demonstration projects at the appropriate time.
