The use of biomass, wood in particular, is one of the oldest forms of producing energy for heating or cooking. Nowadays, new technologies concerning the utilisation of biomass or waste residues are in demand and the trend to use them in decentralised applications for combined heat and power...

A thermally reduced graphene oxide (TRGO) grown with carbon nanotubes composite (G-CNT) was utilized as three-dimensional highly conductive carbon scaffolds, where a large amount of small and homogeneous Pt nanoparticles (from 3.37 ± 1.22 to 4.24 ± 1.83 nm) was directly synthesized on...

For the evaluation of potential routes for production and application of hydrogen in a future energy system, well-to-wheel (WtW) methodologies provide a means of comparing overall impacts of technologies and fuels in a consistent and transparent manner. Such analysis provides important...

This paper aims at selecting different types of fuel cells using an MINLP (mixed-integer nonlinear programming) model, whilst considering the usage of waste hydrogen from the outlet gas. Hydrogen separation from the outlet gas is a good alternative from the economical and environmental perspectives.

This study investigates the potential of energy efficiency, renewables, and micro-cogeneration to reduce household consumption in a medium Italian town and analyses the scope for municipal local policies. The study also investigates the effects of tourist flows on town's energy consumption by...

High-quality nano-sized Ce0.8Dy0.2O2−δ powders were synthesized by the solution combustion method, using C4H7NO4 (aspartic acid) as the combustion fuel. The nano-sized Ce0.8Dy0.2O2−δ powders provided an ultra-fine grain size and high density even at low sintering temperatures...

In this report, we describe the preparation of OMC (ordered mesoporous carbon) via a conventional templating method using mesoporous silica (SBA-15) as a Pt–Ru catalyst support for use in fuel cells. The influence of surface treatment of the carbon supports on the electrochemical properties of...

Hydrogen is an especially attractive transportation fuel. It is the least polluting fuel available, and can be produced anywhere there is water and a clean source of electricity. A fuel cycle in which hydrogen is produced by solar-electrolysis of water, or by gasification of renewably grown...

Fuel cells are a promising technology for combined heat and power (CHP); however their efficiency and carbon benefits are often overlooked because of their reliance on fossil fuels. This paper sets out the numerical methods and evidence of real-world performance needed to compare fuel cells with...

There are three systems and applications of fuel cells in China, namely transportation fuel cells, stationary systems and portable fuel cells. It is important for China to analyze the supply and the cost of fuel cells in the context of the energy crisis. After introducing the current situation...
