Regenerative Energie
The development of a sustainable society requires reduction of dependency on fossil fuels and of the amount of pollution generated from human activities. The treatment of solid waste and of wastewater is an area in which these two goals can be simultaneously achieved. Biological Hydrogen Production is an interesting opportunity to produce hydrogen from renewable source, at low costs and sustainable environmental impacts.
Energy is fundamental for life and the development of the society. The global energy request is satisfied from fossil fuels which are currently used as primary energy source and found economic convenience for transport and production of energy for industrial and house requests. Emerging scientific evidences are proving climate change effects from the use of fossil fuels caused by the emissions of COx, NOx, SOx, CxHx, dust and ash, produced during combustion processes and released in atmosphere. Hydrogen is receiving higher interest to avoid fossil fuels consumption and climate changing. It cannot be considered as a primary energy source but it could be transported, stored and used like other primary energy sources. Hydrogen is the most plentiful element in the universe making up about three-quarter of all the matter. The atmosphere contains about 0.07% hydrogen, while the earth’s surface contains about 0.14% hydrogen. Hydrogen is the lightest elements. The mass of one litre of hydrogen is 0.09 g, while the mass of one litre of air is about 1.2 g. Due to its clean and high energy yields (122 kJ/g) hydrogen is a promising candidate as an ideal fuel in the future. In addition, hydrogen has great potential for use as primary or secondary energy source for chemical synthesis or for electrical storage and generation with fuel cells. To avoid carbon dioxide emission in atmosphere, hydrogen has to be produced from renewable source.

Stand der Pumpspeicher in Deutschland 2025
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (12/2025)
Infolge des Ausbaus der Stromerzeugung aus erneuerbaren Energien ist ein erhöhter Speicherbedarf im Stromverbundnetz notwendig. Hierdurch steigt die Bedeutung von Pumpspeichern als bis auf weiteres einzige Möglichkeit für eine großmaßstäbliche Stromspeicherung.
Pumpspeicherkraftwerke - Empfehlungen zur Verkuerzung und Vereinfachung von Genehmigungsverfahren in Deutschland
