Effect of Converter Topology on the Specific Energy Consumption of Alkaline Water Electrolyzers
(IEEE, 2018-10-17)
Water electrolysis will be used to produce renewable hydrogen for energy storage and Power-to-X applications in the future renewable-energy-based energy systems. Therefore, the energy efficiency of hydrogen production will ...
Optimal sizing ratio of a solar PV inverter for minimizing the levelized cost of electricity in Finnish irradiation conditions
(Elsevier, 2019-05-01)
The amount of installed solar power in Finland is increasing as a result of decreasing photovoltaic (PV) system component prices. The growth is especially noticeable in residential systems, and ways to make PV electricity ...
Sensitivity analysis of a PLC-based DSSS anti-islanding system in power distribution grids
(Elsevier, 2019-06-14)
As smart grid applications, distributed generation, and microgrid technologies have become more widespread, new safety-related issues have arisen. Unintentional islanding is an example of a grid fault that may result in ...

Power-to-X technology using renewable electricity and carbon dioxide from ambient air: SOLETAIR proof-of-concept and improved process concept
(Elsevier, 2018-10-15)
This work demonstrates hydrocarbon production directly from water, solar energy, and air—called SOLETAIR. The plant includes direct air capture (DAC) of carbon dioxide, hydrogen production by water electrolysis, and two-step ...
Optimal dimensioning of a solar PV plant with measured electrical load curves in Finland
(Elsevier, 2018)
The amount of installed solar power in Finland tripled in 2016, reaching 27 MWp. In Finland there are no feed-in tariffs, and with the low price of electricity together with the annual distribution of insolation concentrating ...
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 ...
Variable-speed-drive-based method for the cost optimization of air filter replacement timing
(Elsevier, 2021-03-13)
The flow resistance of air filters accounts for a significant share of the electric energy consumed by fan systems. Due to their inevitable fouling, filters must be replaced periodically. This paper presents a novel ...
