As solar and wind energy replace fossil fuels for electricity generation and space heating, the need for seasonal energy storage will increase. Seasonal storage options include pumped hydro, compressed air energy, thermal, hydrogen, and biomass. I will discuss the advantages and disadvantages of each and the role hydrogen can play in seasonal energy storage.
Seasonal Energy Storage Needs
Except for biomass, most seasonal energy storage systems can be quite expensive. Therefore, it is key to size them properly an
The second edition of the Global Energy Assessment (GEA) is a colossus. It contains no less than 1,865 pages of densely packed and informed data, analysis, and possible outcomes. It was written by a global panel of 30 highly specialized authors and reviewed by another 180 energy specialists. The result is as comprehensive as the title promises, ranging from statistics on energy sources and energy consumption to less obvious analyses such as water use by energy sources or the impact of different lifestyles on energy consumption.
The EPB regulations imposed a calculation rationale for heating end use in residential buildings with people’s habits embedded as default values: whole protected volume heated, indoor temperature 18°C, ventilation and internal gains a fixed function of the protected volume, etc.
Measurement of heating end use in hundreds of dwellings and transposing it to the EPB reference year now showed the EPB largely overestimates real use.
