A Techno-economic, Environmental and Risk Analysis (TERA) computational method has been developed for marine propulsion systems. The method comprises several numerical models which simulate the life cycle operation of marine gas turbines installed on marine vessels. Using a system-of-systems...

Researchers at the Pacific Northwest National Laboratory (PNNL) perform fungal research and development activities to support the goal of promoting renewable energy production as set by the U.S. Department of Energy (DOE). This techno-economic analysis assesses the process economics of ethanol...

This paper determines the energy consumption ratio and overall bio-energy production costs of micro-algae cultivation, harvesting and conversion to secondary energy carriers, thus helping to clarify future perspectives of micro-algae production for energy purposes. A limitation growth model is...

It is well-established that microalgal-derived biofuels have the potential to make a significant contribution to the US fuel market, due to several unique characteristics inherent to algae. Namely, autotrophic microalgae are capable of achieving very high efficiencies in converting solar energy...

With its rapid economic development, China has already become the largest emitter of carbon dioxide in the world, facing the pressure from environment and clean energy. In the last decade, the solar photovoltaic (PV) industry in China has developed rapidly, with the joint promotion of the market...

This paper discusses the integration of solar photovoltaic (PV) and battery energy storage (BES) units for reducing energy loss and enhancing voltage stability. Here, each nondispatchable PV unit is converted into a dispatchable source with a combination of PV and BES units. New multiobjective...

This paper describes a novel type of solar concentrator – a rotationally asymmetrical compound parabolic concentrator (RACPC). The RACPC aims at addressing the following objectives: (i) to increase the electrical output of a concentrating photovoltaic (CPV) system by providing sufficient...

This paper presents a mirror symmetrical dielectric totally internally reflecting concentrator (MSDTIRC). Here, its electrical and optical performances are investigated for building integrated photovoltaic applications. This concentrator is designed to tackle two issues: (i) providing sufficient...

In the last decade, China’s photovoltaic (PV) industry has developed rapidly, with the joint promotion of the world market and domestic policies, and China has now become the largest PV manufacturer in the world. Meanwhile, the international market has responded to China’s rapid development,...

This paper describes a novel type of solar concentrator – a mirror symmetrical dielectric totally internally reflecting concentrator (MSDTIRC). This new concentrator type has been designed to satisfy the following objectives: (i) to provide optimum gain in two different planes, therefore...
