Applications & Pathways

Electrifying energy-intensive processes is currently intensively explored to cut greenhouse gas (GHG) emissions through renewable electricity. Electrification is particularly challenging if fossil resources are not only used for energy supply but also as feedstock. Copper production is such an energy-intensive process consuming large quantities of fossil fuels both as reducing agent and as energy supply.Here we explore the techno-economic potential of Power-to Read More

Tropical climate is characterized by hot temperatures throughout the year. In areas subject to this climate air conditioning represents an important share of total energy consumption. In some tropical islands there is no electric grid; in these cases electricity is often provided by diesel generators. In this study in order to decarbonize electricity and cooling production and to improve autonomy in a standalone application a microgrid producing combined coo Read More

This paper discusses the numerical modeling of an automobile fuel cell system using a two-stage turbo-compressor for air supply. The numerical model incorporates essential input parameters for air and hydrogen flow. The model also performed mass and energy balances across different components such as pump fan heat-exchanger air compressor and keeps in consideration the pressure losses across flow pipes and various mechanical parts. The c Read More

About 400 million tonnes of plastics are produced per annum worldwide. End-of-life of plastics disposal contaminates the waterways aquifers and limits the landfill areas. Options for recycling plastic wastes include feedstock recycling mechanical /material recycling industrial energy recovery municipal solid waste incineration. Incineration of plastics containing E-Wastes releases noxious odours harmful gases dioxins HBr polybrominated diphenylethers and ot Read More

The remaining useful life (RUL) prediction for hydrogen fuel cells is an important part of its prognostics and health management (PHM). Artificial neural networks (ANNs) are proven to be very effective in RUL prediction as they do not need to understand the failure mechanisms behind hydrogen fuel cells. A novel RUL prediction method for hydrogen fuel cells based on the gated recurrent unit ANN is proposed in this paper. Firstly the data were preproc Read More

The future energy system is widely expected to show increasing levels of integration across differing energy carriers. Electricity hydrogen methane and heat systems may become increasingly interdependent due to coupling through conversion and hybrid energy technologies. Market parties network operators policy makers and regulators require tools to capture implications of possible techno-economic and institutional developments in one system for t Read More

The electric power industry sector has become increasingly aware of how counterproductive voltage sag affects distribution network systems (DNS). The voltage sag backfires disastrously at the demand load side and affects equipment in DNS. To settle the voltage sag issue this paper achieved its primary purpose to mitigate the voltage sag based on integrating a hydrogen fuel cell (HFC) with the DNS using a distribution static synchronous compensa Read More

The influence of the initial tank temperature on the evolution of the internal gas temperature during the refuelling of on-board hydrogen tanks is investigated in this paper. Two different types of tanks four different fuel delivery temperatures (from ambient temperature refuelling to a pre-cooled hydrogen at −40 °C) several filling rates and initial pressures are considered. It has been found that the final gas temperature increases linearly with the increase of th Read More

This study outlines a pathway for commercialisation of stationary fuel cells in distributed generation across Europe. It has been sponsored by the Fuel Cells and Hydrogen Joint Undertaking (FCH JU) a public-private partnership between the European Commission the fuel cell and hydrogen industry and a number of research bodies and associations. The FCH JU supports research technology development and demonstration activities in the field of fuel cell and Read More

This paper aims to expand current thinking about the future of energy and water utility provision by presenting a radical idea: it proposes a combined delivery system for household energy and water utilities which is inspired by an analogy with the human body. It envisions a multi-functional infrastructure for cities of the future modelled on the human circulatory system. Red blood cells play a crucial role as energy carriers in biological energy distributio Read More
