Thermodynamic modelling of hydrogen production in sorbent-enhanced biochar-direct chemical looping process

Zezhong Li

Hydrogen (H-2) has been widely considered the clean energy carrier of choice for emerging renewable energy generation technologies. However, H-2 is a secondary fuel mainly derived from natural gas. Over the past decades, research on developing H-2 producti ...

Fine Particle Iron in Soils and Road Dust Is Modulated by Coal-Fired Power Plant Sulfur

Athanasios Nenes

Transition metal ions, such as water-soluble iron (WS-Fe), are toxic components of fine particles (PM2.5). In Atlanta, from 1998 to 2013, a previous study found that WS-Fe was the PM2.5 species most associated with adverse cardiovascular outcomes. We exami ...

Health effects of power plant emissions through ambient air quality

Christine Choirat

Coal burning power plants are a frequent target of regulatory programmes because of their emission of chemicals that are known precursors to the formation of ambient particulate air pollution. Health impact assessments of emissions from coal power plants t ...

Enhancing the operational flexibility of thermal power plants by coupling high-temperature power-to-gas

François Maréchal, Jan Van Herle, Ligang Wang, Yang Sun

The increasing penetration of intermittent renewable power challenges the stability of the electrical grid, thus coal power plants are usually required to extend the operation range by reducing the minimum load. This work proposes a concept of coupling sol ...

Underground Pumped Storage Hydropower Case Studies in Belgium: Perspectives and Challenges

Elena Vagnoni, Alessandro Morabito

To avoid the geographical and topographical prerequisites of the conventional pumped hydro energy storage, the use of underground cavities as water reservoirs allows countries without steep topography, such as Belgium, to increase the potential of the ener ...

Cutting the cost of carbon capture: a case for carbon capture and utilization

Berend Smit

A significant part of the cost for carbon capture and storage ( CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific ...

Online Detection of Selenium and Its Retention in Reducing Gasification Atmosphere

Christian Ludwig, Andrea Testino, Adrian Hess

The emission of selenium from coal gasification processes can cause harm to the environment and downstream equipment. With upcoming legislation, reliable detection as well as control of such gas species become crucial. This study therefore addresses the de ...

Review of fly ash inertisation treatments and recycling

Rudolf Paul Wilhelm Jozef Struis

Fly ash (FA) is a by-product of power, and incineration plants operated either on coal and biomass, or on municipal solid waste. FA can be divided into coal fly ash, obtained from power plant burning coal, flue gas desulphurisation FA, that is, the by-prod ...

A Metamodel of the Oil Game under Climate Treaties

Marc Vielle

A climate treaty like the one which should replace the Kyoto Protocol after 2012, may have important impacts on the oil, gas and coal markets. The full impact of such a treaty will not be felt before 2030. In this paper one uses a computable general equili ...

Methodological Aspects of the Definition of a 2kW Society

Daniel Favrat, Pierre-André Haldi

The consumption of primary energy is often used to compare energy systems from a sustainability viewpoint at regional, national or even world level. For such comparisons to be “fair” and meaningful, this implies however to define primary energies in a cohe ...
