China awakes to clean transportation
In the following months and at least until the Beijing Olympic Games in 2008, Chinese roads and cities, particularly in Beijing and Shanghai, will be a choice testing ground for different types of clean individual and collective low-pollution vehicles, such as fuel cell, hybrid and electric vehicles. We already knew that hybrid microturbine buses were to be road tested in China. Now ...

The impact of national environmental policy on the global success of next-generation automobiles
In this paper, we identify the most crucial factors of the potential world market success of alternative car designs: fuel cell vehicles (FCVs), hybrid electric vehicles (HEVs), battery electric vehicles (BEVs), and conventional fuel efficient vehicles (FEVs). We assess which vehicle concept is favoured under which regulation regime. We suggest that the global success of a certain technology ...

Greenhouse gas emissions of fossil fuel-fired power plants: current status and reduction potentials, case study of Iran and Canada
In this paper, methodology to estimate GHG emissions from electricity generation sector using Iran as an example was first explained. Then different scenarios to reduce GHG emissions were evaluated for two countries: Canada and Iran. The results demonstrated that there were great potentials for GHG emission reduction in both countries. These potentials were evaluated by introducing eight ...

Evaluating advanced automotive energy technologies: a multivariate mobility contribution metric
Mobility technology is beginning to shift from gasoline-fuelled, internal combustion engines to a variety of alternate fuels and powertrains, including hybrid and fuel cell vehicles. The benefits and/or limitations of many of these technologies are not well characterised by a simple fuel economy metric: mobility is a complex system requiring a multivariate systems measure, especially ...

The hydrogen loop: the means for making the hydrogen economy realistic
The hydrogen economy has already started with the introduction of the Ovonic nickel metal hydride battery, which has enabled the rapid growth of hybrid vehicles. Reversible storage of hydrogen in a solid hydride permits the entire loop of hydrogen generation, storage and use, all of which have been placed some time in the future. It is often stated that the hydrogen infrastructure does not exist ...

Power management policies and control of hybrid electric vehicle
With increasing concern over the environment and ever-stringent emission regulations, the use of hybrid electric vehicle (HEV) is being investigated as an alternative form of transportation. A hybrid vehicle combines the advantages of an electric drive and an internal combustion engine. This paper proposes the necessary hardware and software needed for an effective control of the electrical part ...

Coming In Out of the Cold: Hybrids Put to the Test
Untitled Document Point Roberts, WA, Delta B.C.- May 25, 2004 With gas prices reaching an all time high and not much promise of an end in sight, hybrid technology is falling under the lens of some careful scrutiny these days with investors. In a recent article in MIT’s Technology Review, author Peter Fairley estimates “though buyers would have to pay more ...

How Many Cells do I Need in my Fuel Cell? (Simple Fuel Cell Design Guide)
As with Electrolyzers on my previous post, there are many nuances in the optimal design of a Fuel Cell. The proper selection depends on the application, type of fuel cell, component selection and design (MEAs, flow fields, etc.) and a host of other factors. However, I will start with a simple tool that will help determine some general characteristics of a typical H2/Air fuel cell. Thanks to ...

A novel stabilisation scheme for hybrid photovoltaic, fuel–cell and diesel gen–set utilisation system
The paper presents a novel FACTS–based modulated filter compensator scheme for a hybrid renewable photovoltaic–diesel–fuel cell common DC bus interface scheme. The proposed standalone photovoltaic–diesel–fuel system is fully interfaced using the common AC–DC collection bus topology. This allows for full decoupling of AC and DC type green source and ensures full flexibility in controlling the ...

Planet Before Profit
The question of Profit before Planet is not tenable anymore. It is too selfish to think of Wealth at the cost of Planet. Unfortunately, it is still not sinking in our mind @ speed at which it should except Greta Thunberg (Sweden), Adelaide Charlier (Belgium), Luisa Neubauer (Germany), Xyie Bastida (Mexico), Prof Johan Rockstrom, most influential Earth Scientist (Sweden) and David Attenborough ...
