Energy storage

Energy storage is the capture of energy produced at one time for use at a later time [1] This stored energy can be used at a later time when demand for electricity increases or energy resource availability decreases. To exceed a self-sufficiency of 40% in a household equipped with photovoltaics,

Hybrid Hydrogen Home Storage for Decentralized Energy

A self-sufficient energy supply with hydrogen storage has already been realized for single- and multi-family dwellings [31, 32], as well as for residential districts [33], and there are commercial suppliers that offer all-in-one hydrogen solutions for residential storage. 2 These implementations show that a viable degree of autarky 3 for energy

Modeling building energy self-sufficiency of using rooftop

The significant contribution of buildings to global energy-related CO 2 emissions and climate change has led to projections of a carbon–neutral building stock by 2050. This study evaluates the potential contribution of rooftop photovoltaics to urban energy self-sufficiency by developing an enhanced CityBEM framework, our in-house urban building energy model (UBEM).

Energy self-sufficiency, grid demand variability and consumer

The degree of household electricity self-sufficiency is defined by the proportion of demand met by local generation, i.e. not imported from the grid. Thus, the annual proportion of imported electricity is determined for each household simulation and the impact on self-sufficiency of each parameter listed in Table 1 is analysed. The individual

A systematic review of building energy sufficiency towards energy

Energy sufficiency is commonly confused with energy efficiency, which is a term representing the relative relationship between energy input and effect output; it is possible for a building to be both energy-efficient and energy consumption intensive. The results showed energy and computational time savings of approximately 5% and 70%

Green Transformation of Mining towards Energy Self-Sufficiency

This article presents the concept of green transformation of the coal mining sector. Pump stations that belong to Spółka Restrukturyzacji Kopalń S.A. (SRK S.A., Bytom, Poland) pump out approximately 100 million m3 of mine water annually. These pump stations protect neighboring mines and lower-lying areas from flooding and protect subsurface aquifers
