Reductive catalytic fractionation (RCF) is a promising approach to fractionate lignocellulose and convert lignin to a narrow product slate. To guide research towards commercialization, cost and sustainability must be considered. Here we report a techno-eco ...
Thermodynamics and heat engines are the core disciplines which enabled the development of the thermo-industrial society during the 20th century. Liquid hydrocarbon fuels are one of the easiest and most convenient solutions offered by the thermophysical con ...
This article presents the exergoeconomic evaluation of a new geothermal-based integrated system, which produces hydrogen and freshwater. The proton exchange membrane electrolyzer (PEME) and humidifier-dehumidifier (HDH) units are responsible for hydrogen a ...
Towards decarbonizing the global economy, hydrogen produced through water electrolysis is expected to be one of the key solutions for variable renewable energy storage and sector coupling, in particular, via the transport sector in the next few decades. Ev ...
To limit climate change by reducing global greenhouse gas emissions, a transition away from fossil fuels is required. Biofuels represent a promising low carbon alternative for sectors that are hard to electrify, such as aviation. The integration of bio ref ...
A redox dual-flow battery is distinct from a traditional redox flow battery (RFB) in that the former includes a secondary energy platform, in which the pre-charged electrolytes can be discharged in external catalytic reactors through decoupled redox-mediat ...
The electrochemical splitting of water holds promise for the storage of energy produced intermittently by renewable energy sources. The evolution of hydrogen currently relies on the use of platinum as a catalyst-which is scarce and expensive-and ongoing re ...
Hydrogen fuel cell is a promising green technology that transforms the chemical energy in hydrogen into electricity. Currently, most of the efforts are focused on developing proton exchange membrane fuel cells (PEMFCs), however they are heavily dependent o ...
Ammonia (NH3) has 17.8 wt% hydrogen and is easily liquified at 25°C and 8 bar pressure. Ammonia is carbon-free and can be produced sustainably at large scale and low cost. Solid oxide fuel cells generate electricity with efficiencies greater than 60% and c ...
Urban planning in the twentieth century has expressed as one of its main objectives its concern for the health of cities. With the advent of the hygiene movement and the decentralization of industry, new urban models and rationalities came into practice, e ...
