Alternative uses of waste for energy production become increasingly interesting when considered from two perspectives, that of waste management and the energy system perspective. This paper presents the results of an enquiry into the use of waste in a future energy system. The analysis was performed using the energy system analysis model, Balmorel. The study is focused on Germany and the Nordic countries and demonstrates the optimization of both investments and production within the energy systems. The results present cost optimization excluding taxation concerning the use of waste for energy production in Denmark in a 2025 scenario with 48% renewable energy. Investments in a range of waste conversion technologies...

The global climate problem becomes tractable if CO2 emissions from coal use are phased out rapidly and emissions from unconventional fossil fuels (e.g., oil shale and tar sands) are prohibited. This paper outlines technology options for phasing out coal emissions in the United States by similar to 2030. We focus on coal for physical and practical reasons and on the U.S. because it is most responsible for accumulated fossil fuel CO2 in the atmosphere today, specifically targeting electricity production, which is the primary use of coal. While we recognize that coal emissions must be phased out globally, we believe U.S. leadership is essential, A major challenge for reducing U.S. emissions is that coal provides the...

The horizontal drilling and hydrofracturing techniques used for extraction of natural gas from shales of the Marcellus Formation (USA) lead to production of significant volumes of high-TDS (total dissolved solids) waters that have interacted with the source shale and potentially adjacent units. Determining the source of these dissolved salts and understanding local and basinal variations in TDS have direct relevance to exploration methodologies and water management and reclamation. A series of flowback waters have been collected from drilling operations in a geographic region spanning ~375 km, from northeastern to southwestern Pennsylvania. Most 87Sr/86Sr values fall within a narrow range, from 0.7101 to 0.7112;...
