This study focuses on the optimization of green ammonia production systems through a mixed-integer linear programming (MILP) framework. The proposed model integrates both design decisions and detailed annual operational strategies, evaluated at an hourly r ...

Coupling a biomass gasifier with a solid oxide fuel cell system through a high-temperature syngas compressor holds great promise to achieve low-emission, small-scale combined heat and power, since it reduces the number of heat exchangers and increases the ...

We carry out a weakly nonlinear analysis of the centrifugal instability for a columnar vortex in a rotating fluid, and compare the results to those of the semi-linear model derived empirically by Yim et al. (J. Fluid Mech., vol. 897, 2020, A34). The asympt ...

Rational design of non-noble metal electrocatalysts with high intrinsic activity for both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is extremely impressive for sustainable electrocatalytic water splitting systems. However, i ...

Utilizing earth-abundant metals to design economical and efficient electrocatalysts for cathodic hydrogen evolution reaction (HER) and anodic oxygen evolution reaction (OER) is critical for acquiring clean hydrogen energy by the electrochemical overall wat ...

The combination of porous reticular frameworks and nanocrystals (NCs) offers a rich playground to design materials with functionalities, which are beneficial for a large variety of applications. Achieving compositional and structural tunability of these hy ...

Interest in the hydraulic and mechanical characterization of shales has grown in recent years, because of their application in the context of energy geotechnics. In the frame of nuclear waste disposal shales are considered as host formations for the placem ...

Improving the throughput of electrochemical reactions such as water electrolysis is an ongoing effort. In a membrane-less electrolyzer, product separation can be achieved via controlled two-phase flows within the electrochemical flow cells. In this case, i ...

Modern ammonia production plants are equipped with efficient energy integration networks able to recover an important fraction of the waste heat exergy available throughout the chemical system. However, in order to drive the endothermic reforming reactions ...

The hydrogen storage properties and crystal structures of YMgNi4-based alloys, which were synthesized from (2 - x)YNi2 and xMgNi(2) (0.6

Solar technologies hold the potential to ultimately counteract the effects of climate change. Nevertheless, the intermittency of sunlight poses technical challenges regarding the storage of the surplus production and the supply of the deficit. The generat ...

To handle global problems of energy and environmental pollution, efforts have been made to harvest energy from sunlight. Photoelectrochemcal water splitting is an efficient way to achieve sustainable solar-fuel production. However, to make this method comp ...

Pressurised water supply systems are infrastructures that offer a potential for energy recovery in locations where these systems operate with an excessive pressure. The integration of micro hydropower plants for energy recovery is a challenge, as these sys ...

The low temperature boundary layer plasma (scrape-off layer or SOL) between the hot core and the surrounding vessel determines the level of power loading, erosion and implantation of material surfaces, and thus the viability of tokamak-based fusion as an e ...
