Analysis of Lifecycle Water Requirements of Energy & Transportation Fuels: Electricity from Geothermal Resources - Model Description [PDF]

open access: yes, 2010
A model is developed to estimate water requirements for electricity from various forms of geothermal resources. It considers two types of hydrothermal resources, wet steam and hot water, as well as enhanced geothermal systems (EGS).

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Transonic Flow of Wet Steam — Numerical Simulation

open access: yesActa Polytechnica, 2012
The paper presents a numerical simulation of the transonic flow of steam with a non-equilibrium phase change. The flow of steam is approximated by a mixture model complemented by transport equations for moments. Proper formulation of the problem consists

Effective pretreatment of wet microalgal biomass to enhance lipid extraction in biodiesel production

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biodiesel is a viable alternative to fossil fuels. Identifying and evaluating nonedible sources is essential to address ecological concerns and meet energy demands. Microalgae are effective for lipid production but their rigid cell walls hinder bioproduct release making the process energy‐intensive and costly.

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...
