WASHINGTON, March 14 /PRNewswire-USNewswire/ -- Leading academics from an interdisciplinary Massachusetts Institute of Technology (MIT) panel issued a report today that examines how the world can continue to use coal, an abundant and inexpensive fuel, in a way that mitigates, instead of worsens, the global warming crisis. The study, "The Future of Coal -- Options for a Carbon Constrained World," advocates the U.S. assume global leadership on this issue through adoption of significant policy actions.
Led by co-chairs Professor John Deutch, Institute Professor, Department of Chemistry, and Ernest J. Moniz, Cecil and Ida Green Professor of Physics and Engineering Systems, the report states that carbon capture and sequestration (CCS) is the critical enabling technology to help reduce CO2 emissions significantly while also allowing coal to meet the world's pressing energy needs.
According to Dr. Deutch, "As the world's leading energy user and greenhouse gas emitter, the U.S. must take the lead in showing the world CCS can work. Demonstration of technical, economic, and institutional features of CCS at commercial scale coal combustion and conversion plants will give policymakers and the public confidence that a practical carbon mitigation control option exists, will reduce cost of CCS should carbon emission controls be adopted, and will maintain the low-cost coal option in an environmentally acceptable manner."
Dr. Moniz added, "There are many opportunities for enhancing the performance of coal plants in a carbon-constrained world -- higher efficiency generation, perhaps through new materials; novel approaches to gasification, CO2 capture, and oxygen separation; and advanced system concepts, perhaps guided by a new generation of simulation tools. An aggressive R&D effort in the near term will yield significant dividends down the road, and should be undertaken immediately to help meet this urgent scientific challenge."
Key findings in this study:
-- Coal is a low-cost, per BTU, mainstay of both the developed and
developing world, and its use is projected to increase. Because of
coal's high carbon content, increasing use will exacerbate the problem
of climate change unless coal plants are deployed with very high
efficiency and large scale CCS is implemented.
-- CCS is the critical enabling technology because it allows significant
reduction in CO2 emissions while allowing coal to meet future energy
needs.
-- A significant charge on carbon emissions is needed in the relatively
near term to increase the economic attractiveness of new technologies
that avoid carbon emissions and specifically to lead to large-scale CCS
in the coming decades. We need large-scale demonstration projects of
the technical, economic and environmental performance of an integrated
CCS system. We should proceed with carbon sequestration projects as
soon as possible. Several integrated large-scale demonstrations with
appropriate measurement, monitoring and verification are needed in the
United States over the next decade with government support. This is
important for establishing public confidence for the very large-scale
sequestration program anticipated in the future. The regulatory regime
for large-scale commercial sequestration should be developed with a
greater sense of urgency, with the Executive Office of the President
leading an interagency process.
-- The U.S. government should provide assistance only to coal projects
with CO2 capture in order to demonstrate technical, economic and
environmental performance.
-- Today, IGCC appears to be the economic choice for new coal plants with
CCS. However, this could change with further RD&D, so it is not
appropriate to pick a single technology winner at this time, especially
in light of the variability in coal type, access to sequestration
sites, and other factors. The government should provide assistance to
several "first of a kind" coal utilization demonstration plants, but
only with carbon capture.
-- Congress should remove any expectation that construction of new coal
plants without CO2 capture will be "grandfathered" and granted emission
allowances in the event of future regulation. This is a perverse
incentive to build coal plants without CO2 capture today.
-- Emissions will be stabilized only through global adherence to CO2
emission constraints. China and India are unlikely to adopt carbon
constraints unless the U.S. does so and leads the way in the
development of CCS technology.
-- Key changes must be made to the current Department of Energy RD&D
program to successfully promote CCS technologies. The program must
provide for demonstration of CCS at scale; a wider range of
technologies should be explored; and modeling and simulation of the
comparative performance of integrated technology systems should be
greatly enhanced.
