This work aims to develop an accurate energy management strategy for a hybrid renewable energy system feeding a pumping station. A developed model under Simulink environment is used to compare the performance of the pumping system when it is only fed by a photovoltaic generator, by a hybrid photovoltaic and fuel cell system and finally by a hybrid photovoltaic, fuel cell and a supercapacitor sy...

Accounting for transportation is an important part of the life cycle analysis (LCA) of beef cattle production because it is associated with energy consumption and greenhouse gas emissions. This paper describes the development and application of a model that estimates energy consumption and greenhouse gas emissions of transport in beef cattle production. The animal transport model is based on th...

This paper addresses the relative suitability of nuclear and solar in Australia as a primary future electricity option, since nuclear can use abundant Australian resources of U235, but the direct solar option is the biggest global resource. The background is that we are likely to need generation systems which use close to zero net emissions by mid-century. There are many energy options, but few...

Several technologies are being used in distributed generation applications with variable degree of success. Among those are: wind turbines, small-scale hydropower plants, biomass, microturbines, photovoltaic arrays and fuel cells. In a fuel cell, the chemical energy incorporated in the fuel is converted directly to electricity and heat. Fuel cell technology is one of the most interesting energy...

1.Introduction Energy efficiency and environmental performance are mainstream issues for ship operators who are aiming through low carbon shipping and cost reductions. Although reducing fuel consumption seems to have priority, environmental considerations also push the shipping industry to operate in more efficient way. Strict legislations on GHG emissions and increasing fuel prices turn the fo...

Alternative fuel usage is becoming a more and more prevalent topic of discussion and important research area for those who work in the energy field and perform research on energy topics. This interest is due to the dwindling supply and increasing cost of more traditional energy supplies, as well as environmental considerations. Bio-fuels have now become an important research area as they have t...

Ð Promoting sustainable development requires evaluating the technical and policy options that will facilitate the adoption and use of energy ecient and less polluting cooking stoves and practices. The transition from traditional to modern fuels and devices has been explained by the ``energy ladder'' model that suggests that with increasing a‚uence, a progression is expected from traditional bi...

Tea industry plays a major part in the economy of the North Eastern region of India. About 54% of the tea produced in India comes from North East region. The energy requirement of the industry is high and is being provided by utilization of conventional fuel till now. But the increasing prices of fossil fuel have affected the economy of the industry and the production prices have gone up. This ...

Ultra-portable devices like wireless autonomous sensors can be as ubiquitous as cellular phones, if not more, because, among other things, they can retrofit and convert older macro-scale technologies that are difficult to upgrade and expensive to replace in places like factories, power plants, hospitals, and every-day living spaces into intelligent energyand power-efficient solutions [1]. The p...

Fuel cells are generally considered as a clean, efficient and silent technology that can produce electricity and heat from fossil fuels, biofuels as well as hydrogen produced from renewable energy sources such as wind energy and solar energy. The expectations with respect to their commercial introduction in transport as early as 2003 and stationary applications by 2001 held since the mid 1990s ...
