Oxy-fuel coal combustion with flue gas re-circulation is known to be one of the most promising methods for reducing CO2 emissions from coal combustion power plants. In the oxy-fuel system, the combustion atmosphere consists of only O2 separated from air and flue gas re-circulated from a stack. Therefore, the flue gas is dominated by CO2 without any nitrogen gas. The most attractive potential as...

Modern civilization is dependent upon fossil fuels, a nonrenewable energy source originally provided by the storage of solar energy. Fossil-fuel dependence has severe consequences, including energy security issues and greenhouse gas emissions. The consequences of fossil-fuel dependence could be avoided by fuel-producing artificial systems that mimic natural photosynthesis, directly converting s...

reduction of exhaust emissions is a major research task in diesel engine development in view of increasing concerns regarding environmental protection and stringent exhaust gas regulations. simultaneousreduction of nox emissions and particulate matter is quite difficult due to the soot/nox trade-off and isoften accompanied by fuel consumption penalties. towards this aim, automotive engineers ha...

This article introduces an on-demand microfluidic hydrogen generator that can be integrated with a microproton exchange membrane (PEM) fuel cell. The catalytic reaction, reactant circulation, gas/liquid separation, and autonomous control functionalities are all integrated into a single microfluidic device. It generates hydrated hydrogen gas from an aqueous ammonia borane solution which is circu...

New energy technologies are needed to limit CO2 emissions and the detrimental effects of global warming. In this article we describe a process which produces a low-carbon gaseous fuel from coal. Synthesis gas from a coal gasifier is shifted to a gas mixture consisting mainly of H2 and CO2. The CO2 is isolated by a physical absorption process, compressed, and transported by pipeline to a deplete...

Various recently proposed biomass fuels are reviewed from the point of view of their safety. Many biomass materials are proposed for use as fuels, such as refuse derived fuel (RDF), wood chips, coal-wood mixtures, etc. However, these fuels have high energy potentials and can cause fires and explosions. We have experienced many such incidents. It is very difficult to extinguish fires in huge pil...

As a new type of functional materials, porous metal–organic frameworks (MOFs) have experienced tremendous development in the past decade. Their amenability to design, together with the functionalizable nanospace inside their frameworks, has afforded them great potential for various applications. In this review, we provide a brief summary of the current status of porous MOFs in energy-related ap...
