At the Laboratory for Transport Phenomena in Energy Systems, we research several sustainable energy technologies and their applications, including fuel cells, batteries, supercapacitors, and CO2 capture technologies.
With ever-increasing concerns over climate change and energy independence, the development of sustainable energy systems and pollution abatement technologies are prominent on the global agenda. However, significant research and development are required to realize sustainable energy technologies that are economically feasible and publicly acceptable.
Energy & Fuels has published research from the TPES group regarding steam-coal gasification with in-situ carbon capture. This work was a collaboration between TPES and the DoE's National Energy Technology Laboratory (NETL). MORE
This month, Energy and Environmental Science accepted and pre-published a manuscript by Siefert et al. on the steam gasification of coal and molten alkali hydroxides, producing hydrogen and methane while the hydroxides capture both carbon and sulphur species.MORE
The Journal of the Electrochemical Society has published the work done by Katherine Hess, Jay Whitacre and Shawn Litster on measuring electric potential, current and charging current in aqueous sodium hybrid batteries.MORE
The Journal of Physical Chemistry C has published an article by Zenyuk and Litster. The paper presents a multi-scale model of coupled proton transport and reaction kinetics in water-filled mesopores of a PEFC anode.
The International Journal of Hydrogen Energy recently published a short communication by Epting and Litster. Its focus: the effect of a real agglomerate size distribution on the agglomerate model of a PEFC electrode.MORE
On 2 December 2011, Epting presented "Nano-Scale X-Ray Computed Tomography of Polymer Electrolyte Fuel Cell Electrodes" at the 2011 MRS meeting in Boston, MA. Click to see the presentation in its entirety. MORE
Advanced Functional Materials has published a paper on nanoscale X-ray CT of a fuel cell electrode by Epting, Litster, and external collaborator Gelb (Xradia Inc.). The paper describes the 3D imaging of the porous electrode at 50 nm resolution, as well as a comprehensive analysis and validation using other techniques.MORE
Analytical Chemistry has published an article by the TPES lab (Hess et al.) that describes the first in-situ measurements of ionic potential across the thickness of a fuel cell electrode, which was achieved using the lab’s unique micro-structured electrode scaffold (MES) diagnostics.MORE
EPA-STAR fellow and TPES member Billy Epting attended the official EPA-STAR conference on 19 and 20 September 2011 in Washington, D.C., presenting a poster and a new infographic on the importance fuel cell and battery research.MORE
TPES researcher Kacy Hess was awarded a Dowd Fellowship for the 2011-2012 academic year. This fellowship will fund her work studyingin-situ, through-plane distribution measurements in aqueous hybrid batteries for grid-scale energy storage.MORE
Nick Siefert and Billy Epting presented at the combined ASME Fuel Cell Science, Engineering & Technology and Energy Sustainability conferences. The meeting was held in Washington, D.C., on 7-10 August 2011.MORE
The EPA awarded Billy Epting a prestigious Science to Achieve Results (STAR) fellowship, to start this year. The three-year fellowship provides funding for graduate studies and research expenses in fields related to the environment.MORE
