Renewable hydrogen may be produced in the near term at a cost that is competitive with natural gas reforming by integrating hydrogen production with existing industrial utilization of agricultural residues. A team of government, industrial, and academic organizations is developing a steam reforming process to be demonstrated on the gaseous byproducts from a process for making activated carbon f...

For the open loop control system based on solar position algorithm (SPA), without sensor correction, error of SPA will bring tracking directly to decrease efficiency system. By comparing with proposed by NREL, this paper first evaluates main SPAs different accuracy and presents error. Based annual average trough system, impact caused proposes that calculation can be applied characterize making ...
پره های روتور اصلی ترین بخش توربین های بادی هستند. خصوصیات آئرودینامیکی توربین های بادی وابسته به شکل هندسی پره هایشان بوده و خصوصیات پره ها به نوبه خود وابسته به پروفیل سطح مقطع آنها می باشد. پروفیل سطح مقطع یک پره معمولا ً به صورت ایرفویل است. قسمت اعظم طراحی یک توربین باد از لحاظ مدت انجام و حجم محاسبات تنها صرف شناسایی نیروهای وارد بر پره توربین می گردد. در این تحقیق مدل هایی از مقاطع پره تو...
Wind turbine manufacturers publish and certify power curves for their turbines. These turbine power curves are used for planning purposes and estimating total wind power production. When a wind plant consisting of many turbines connects to the utility grid and starts operation, the focus shifts to the entire plant’s performance. An equivalent wind plant power-curve becomes highly desirable and ...
(or up to 150 million gallons per year) to BioAlternatives as a feedstock for fuel production. The partners plan to locate algae production and biodiesel refinery facilities in Louisiana. In October 2007, the Chevron Corporation announced a collaborative research project with the DoE's National Renewable Energy Laboratory (NREL) to explore the production of transport fuels, including jet fuel, ...
Abstract Floating offshore wind turbines are easily affected by typhoons in the deep sea, which may cause serious damage to their structure. Therefore, it is necessary study further dynamic response of turbine structures under typhoons. This paper took 5MW floating developed National Renewable Energy Laboratory (NREL) as research object. Based on motion theory platforms waves, a physical model ...
