Neo-Carbon Food concept: A pilot-scale hybrid biological–inorganic system with direct air capture of carbon dioxide
(Elsevier, 2020-08-22)
The pace at which the human population is growing raises serious concerns related to food security while at the same time conventional agriculture-based food production is becoming a major cause of environmental pollution ...
Mitigation of inverter-induced noncirculating bearing currents by introducing grounded electrodes into stator slot openings
(IEEE, 2020-12-23)
Modern converter-supplied AC motors are exposed to bearing currents. Despite extensive research and development, the industry still does not have a final solution with acceptable cost and high efficiency. This paper focuses ...
A life cycle environmental sustainability analysis of microbial protein production via power-to-food approaches
(Springer, 2020-09-21)
Purpose
Renewable energy produced from wind turbines and solar photovoltaics (PV) has rapidly increased its share in global energy markets. At the same time, interest in producing hydrocarbons via power-to-X (PtX) ...
Power quality and reactive power of water electrolyzers supplied with thyristor converters
(Elsevier, 2020-03-28)
Industrial water electrolyzers apply direct current in kiloampere ranges. Therefore, rectifiers are typically based on thyristors despite the high amplitude current fluctuation excited by the rectifier. This paper studies ...
Mitigating noncirculating bearing currents by a correct stator magnetic circuit and winding design
(IEEE, 2020-04-06)
Different mechanisms by which bearing currents flow inside the electrical machine are well studied. In contrast, investigation and development of different techniques to mitigate these currents remain a field for improvement, ...
Effect of power quality on the design of proton exchange membrane water electrolysis systems
(Elsevier, 2020-09-29)
Water electrolyzer technologies may play a key role in the decarbonization of the fossil-fueled world economy. Electrolytic hydrogen production could bridge emission-free power generation and various energy end-use sectors ...
Technical feasibility evaluation of a solar PV based off-grid domestic energy system with battery and hydrogen energy storage in northern climates
(Elsevier, 2020-12-10)
Self-sustaining off-grid energy systems may require both short-term and seasonal energy storage for year-around operation, especially in northern climates where the intermittency in both solar irradiation and energy ...
Electrocatalytic performance and cell voltage characteristics of 1st-row transition metal phosphate (TM-Pi) catalysts at neutral pH
(Elsevier, 2020-06-07)
Water electrolysis represents a clean and sustainable route for large-scale hydrogen generation. However, efficient water splitting is hindered by the kinetically sluggish oxygen evolution reaction (OER), which requires ...
