“Bionic” Liquids from Lignin: Joint BioEnergy Institute Results Pave the Way for Closed-Loop Biofuel Refineries

December 11th, 2014|Categories: Biofuels, Biomass, Capabilities, Energy, Facilities, JBEI, News, News & Events, Partnership, Renewable Energy, Research & Capabilities, Transportation Energy|Tags: , , , , , , , , |

While ionic liquids (paired-ions salts that are liquid at room temperature) show great promise for liberating fermentable sugars from lignocellulose and improving advanced-biofuel economics, an even more promising candidate is now on the horizon—“bionic” liquids. Bionic liquids derived from lignin and hemicellulose show great promise for liberating fermentable sugars from lignocellulose. The current “standard,” imidazolium-based ionic liquids, effectively and efficiently deconstruct biomass into fuel sugars, but are expensive, and thus limited in industrial [...]

Sandia has implemented a scalable parallel capability to model polarized-fluid dynamics in micro devices driven by an electric potential. The Sandia team discretized the mathematical model (Navier-Stokes and Poisson-Bolzman equations) with an implicit smoothed-particle hydrodynamics (SPH) method. Due to the method’s particle nature, the team used the LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) particle library, which was coupled with Trilinos for linear and nonlinear systems solutions. This was the first time that LAMMPS and Trilinos [...]

Inter-Agency Agreement Signed between DOE’s Wind and Water Power Program and Carderock

December 3rd, 2014|Categories: Energy, News, News & Events, Partnership, Renewable Energy, Water Power|Tags: , , , , , , , , |

The Department of Energy (DOE) has launched a multiple-year effort to validate the extent to which control strategies can increase the power produced by resonant wave-energy converter (WEC) devices. Many theoretical studies have shown a promise that additional energy can be captured by controlling the power-conversion chains of resonant WEC devices. The numerical models employed in these studies are, however, idealized to varying degrees. The 12.2-million-gallon Maneuvering and Sea Keeping (MASK) Basin at the [...]
