We are delighted to announce that Energy Science & Engineering has published its inaugural issue.
Since opening for submission in October 2012, Energy Science & Engineering has received high quality of papers across the field of energy research. Published in collaboration with SCI (Society of Chemical Industry), ESE is a peer reviewed, open access journal dedicated to fundamental and applied research on energy supply and use. Priority is given to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy.
Biodiesel from Grease Interceptor to Gas-Tank
Alyse Mary E. Ragauskas, Yunqiao Pu, Art J. Ragauskas
Summary: The need for sustainable biofuels has initiated a global search for innovative technologies that can sustainably convert nonfood bioresources to liquid transportation fuels. While 2nd generation cellulosic ethanol has begun to address this challenge, other resources including yellow and brown grease are rapidly evolving commercial opportunities that are addressing regional biodiesel needs. This review examines the technical and environmental factors driving the collection of trap FOG (Fats, Oils, and Greases), its chemical composition and technologies currently available and future developments that facilitate the conversion of FOG into biodiesel.
Next generation biorefineries will solve the food, biofuels, and environmental trilemma in the energy–food–water nexus
Y.-H Percival Zhang
Summary: The future roles of biomass and carbohydrate for meeting needs of food/feed, renewable materials, and transportation fuels (biofuels) remain controversial due to numerous issues, such as increasing food and feed needs, constraints of natural resources (land, water, phosphate, biomass, etc.), and limitations of natural photosynthesis, as well as competing energy conversion pathways and technologies. The goal of this opinion article is to clarify the future roles of biomass and biorefineries using quantitative data other than adjective words
Lock-in thermography as a tool for quality control of photovoltaic modules
Andreas Vetter, Frank Fecher, Jens Adams, Raymund Schaeffler, Jean-Patrick Theisen, Christoph J. Brabec and Claudia Buerhop
Summary: In this short communication, we present a method which utilizes contactless ILIT (illuminated lock-in thermography) measurement of a photovoltaic (PV) module and image postprocessing in order to calculate the peak power Pmpp of the module and to study the influence of local defects on the module performance. In total, 103 Copper-Indium-Gallium-Diselenide (CIGS) modules were investigated and the results showed a good correlation (mean error less than 6%) between the calculated IR-signal and the measured Pmpp. We performed our study on CIGS modules but the presented approach is not restricted to CIGS modules. The method provides a valuable tool for PV quality control.
