Problems solved by technology

where Ca(OH) 2 / CaO system is an ideal thermochemical energy storage system with high energy storage density (437kWh / m 3 ), non-toxic and good safety, wide and cheap sources of raw materials, no side reactions and high reaction temperature (450°C-600°C), so Ca(OH) 2 / CaO system is used for solar medium-high temperature thermochemical energy storage, which can well solve the problem of continuous and efficient operation of solar medium-high temperature thermal power plants, but currently the Ca(OH) 2 / CaO system for thermochemical energy storage is in its infancy

Description

A kind of calcium hydroxide thermochemical energy storage reactor and energy storage method thereof technical field The invention belongs to the field of solar power generation, relate to a kind of thermochemical energy storage reactor, relate in particular to a kind of hydrogen peroxide Calcium thermochemical energy storage reactor and energy storage method thereof. Background technique Solar power generation has the advantages of wide sources, no environmental pollution, etc., and is an ideal alternative to fossil fuels. clean energy. However, the intermittent and unstable characteristics of solar energy make it difficult to continuously and steadily supply energy. Therefore it is necessary Accelerate research in the science of energy storage, where high-temperature energy storage is a solution to the intermittency and instability problems of renewable energy Efficient latent technology. Among the three main heat storage methods of sensible heat energy storage, ...
