Most rooftop solar photovoltaic (PV) systems must be reviewed and approved by local governments and electric service providers prior to operation. These permitting, inspection, and interconnection (PII) requirements help ensure safe PV system installation and operation, but onerous requirements may needlessly delay construction and operation. Here,...

Outdoor photoautotrophic algal growth is limited by light attenuation and attendant respiratory CO2 losses during dark periods, limiting its productivity potential and carbon use efficiency. Developing a system that leverages mixotrophic growth (combining the benefits of both heterotrophic and photoautotrophic growth) has the potential to dramatica...

About 1 in 10 rooftop solar photovoltaic (PV) customers who sign a contract to install a PV system cancel their contract before the system is installed. Although some cancelation risk is inherent in the solar industry, there may be ways to reduce cancelation volume, such as reducing project delays. Delays can occur at each stage of PV adoption proc...

Research efforts have investigated a range of system designs for algae growth and conversion into biofuels. The economic feasibility and environmental impact of these systems are frequently evaluated through techno-economic analyses (TEA) and life-cycle assessment (LCA), which typically determine the levelized cost of fuel production in gallons of...

Curtailment of solar photovoltaics (PV) could increase significantly as PV composes greater shares of grid capacity. Curtailment risk—the possibility that future curtailment levels exceed projections—poses a challenge to PV project economics. PV industry stakeholders have begun to develop new contract structures that may address curtailment risk mo...

Solar photovoltaic (PV) systems generate electricity with no marginal costs or emissions. As a result, PV output is almost always prioritized over other fuel sources and delivered to the electric grid. However, PV curtailment is increasing as PV composes greater shares of grid capacity. In this paper, we present a novel synthesis of curtailment in...

Objective: Benchmark the economic value of renewable energy and battery storage systems to extend operation of certain critical infrastructure facilities in different markets. Design: This study uses the renewable energy optimization model to assess three critical facilities in North Caro-lina. Techno-economic results were then compared to analy...

This study presents an extensive systems-level multi-pathway sustainability assessment of algae biofuel production that demonstrates the necessity of high-value co-products, examines the impact of public policy scenarios, and identifies improvements and pathway directions required for economic viability. Engineering process models for several fuel...

For the practical implementation of an energy harvesting system, the signal conditioning electronics play an important role in defining the overall efficiency of these power systems. There are currently a number of commercially available energy harvesting circuits designed to condition the output of piezoelectric-based electromechanical transducers...

The purpose of this study was to establish a test setup and vibration analysis method to predict femoral stem seating and prevent bone fracture using accelerometer and force response data from an instrumented stem and impactor. This study builds upon earlier studies to identify a means to supplement a surgeon's tactile and auditory senses by using...
