Assessment of Energy Storage from Photovoltaic Installations Using Hydrogen or Batteries
August 4, 2020This paper presents a series of economic efficiency studies comparing three different investment variants: without energy storage, with energy stored in batteries and hydrogen installation with a PEM fuel cell stack for a location in Poland.
Storing Energy as Hydrogen
November 19, 2020Extensive research on photovoltaics (PV) cooperating with energy storage systems are conducted all over the world. For example, in reference [27] the authors show a PV installation connected with a hydrogen production system. Paper demonstrates that with a proper design of the system proposed by the authors it … Continue reading
Storing Hydrogen
October 19, 2020In some areas, the problem of wind and solar power curtailment is prominent. Hydrogen energy has the advantage of high storage density and a long storage time. Multi-energy hybrid systems including renewable energies, batteries and hydrogen are designed to solve this problem.
Dissociation Of Water Into Hydrogen And Oxygen Through A Combination Of Electrolysis And Photocatalyst
July 28, 2020In this paper, through a review of the literature, a method of separating hydrogen and oxygen from water through a photocatalysis process that utilizes the energy of photons from visible light is combined with the electrolysis process to increase hydrogen production with a fairly small current.
Enhancing Photovoltaic Performance of Porous Silicon Solar Cells
April 21, 2021This work examines nanocrystalline porous silicon (PSi) prepared by electrochemical etching of p type silicon wafers.
Improving Sustainable Hydrogen Production From Green Waste
September 16, 2021Bio-hydrogen production via dark fermentation of low-value waste is a potent and simple mean of recovering energy, maximizing the harvesting of reducing equivalents to produce the cleanest fuel amongst renewables. Here, an alternative application of green wastes, low-value compost and intermediate products (partially composted but unsuitable for completing … Continue reading
Green Hydrogen, Spaceship Earth, and a Circular Economy
December 2020Based on a review of the literature, researchers synthesize some aspects which represent in their understanding the essence of the circular economy concept. While in no way intended to be absolute, definitive and final, these aspects represent a level of understanding of the concept at this specific moment.
Societal Consequences to the Transition to Green Hydrogen
July 15, 2021The need for green hydrogen is likely to require massive expansion of renewable energy plants. Researchers have identified a gap between political action, technological developments, and expertise from the social sciences and humanities as the world transitions from fossil fuels to green hydrogen. They argue that the respective … Continue reading
