| Zusammenfassung |
| Substitution of carbon-intensive coal with less carbon-intensive natural gas for energy
production is discussed as one main pillar targeting reduction of antrophogenic greenhouse
gas emissions by means of climate change mitigation. Other pillars are energy efficiency,
renewable energies, carbon capture and storage as well as further development of nuclear
energy.
Taking into account innovative clean coal technologies such as UCG-CCS (underground
coal gasification with carbon capture and storage), in which coal deposits are developed using
directional drilling technologies and subsequently converted into a synthesis gas of high
calorific value, the coupled conceptual approach can provide a synergetic technology for coal
utilization and mitigation of carbon emissions.
This study aims at the evaluation of UCG´ s carbon mitigation potentials and the review
of the economical boundary conditions. The analytical models applied within this study are
based on data available from world-wide UCG projects and extensive laboratory
studies.
In summary, scenarios considering costs and carbon storage potentials are economically
feasible and thus competitive with less carbon-intensive energy generation technologies such
as natural gas. Thus, coal to gas substitution can be one of the coal based options. |
