Adding Complex Terrain and Stable Atmospheric Condition Capability to the Simulator for On/Offshore Wind Farm Applications (SOWFA)

This presentation describes changes made to NREL's OpenFOAM-based wind plant aerodynamics solver so that it can compute the stably stratified atmospheric boundary layer and flow over terrain. Background about the flow solver, the Simulator for Off/Onshore Wind Farm Applications (SOWFA) is given, followed by details of the stable stratification/complex terrain modifications to SOWFA, along with some preliminary results calculations of a stable atmospheric boundary layer and flow over a simple set of hills.

Benchmarking Soft Costs for PV Systems in the United States

This paper presents results from the first U.S. based data collection effort to quantify non-hardware, business process costs for PV systems at the residential and commercial scales, using a bottom-up approach. Annual expenditure and labor hour productivity data are analyzed to benchmark business process costs in the specific areas of: (1) customer acquisition; (2) permitting, inspection, and interconnection; (3) labor costs of third party financing; and (4) installation labor.

Fermentation and Electrohydrogenic Approaches to Hydrogen Production

This work describes the development of a waste biomass fermentation process using cellulose-degrading bacteria for hydrogen production. This process is then integrated with an electrohydrogenesis process via the development of a microbial electrolysis cell reactor, during which fermentation waste effluent is further converted to hydrogen to increase the total output of hydrogen from biomass.

Impact of ALD Coating on Mn-rich Cathode Materials

LG Chem Power Inc. (LGCPI) and NREL have collaborated to demonstrate the scalability of the atomic layer deposition (ALD) coating process over the last 6 months, and the benefits of ALD coatings for long-term cycling and calendar life are being quantified. The objectives of this work are two-fold: 1) to evaluate the scalability of the process to coat LGCPI cathodes with alumina using the ALD technique, and 2) to demonstrate improvements in rate capability and life of ALD-coated LGCPI electrodes. NREL received samples of baseline material to be coated from LGCPI. NREL carried out ALD coating of the samples with help from a subcontractor, ALD Nanosolutions. NREL fabricated cells from those samples for quick screening and feedback to ALD Nanosolutions. LGCPI is currently fabricating larger-format cells for further evaluation.

Incentivizing Distributed Solar: Best Practices

The presentation discussed findings of a recent NREL technical report on best practices for designing and implementing incentives for small and mid-sized residential and commercial distributed solar energy projects. Topics covered included: factors to consider in setting and modifying incentive levels over time, differentiating incentives to encourage various market segments, and administrative issues such as providing equitable access to incentives and customer protection. In addition, the presentation explored how incentive programs can be designed to respond to changing market conditions while attempting to provide a longer-term and stable environment for the solar industry. The findings of the report were based on interviews with program administrators, regulators, and industry representatives as well as data from numerous incentive programs nationally, particularly the largest and longest-running programs.
