Advances in thermochemical energy storage and fluidised beds for domestic heat

Thermochemical energy storage (TCES) has a vital role to play in future where 100 % of our domestic needs are generated by renewables. Heating and cooling represent 51 total consumption, as such contribute highly greenhouse gas emissions. As society, we have effective solutions for this the form renewable sources, primary two being: solar thermal heat wind power. However, one issue plagues these that is their intermittency. Specifically, seasonal deficit which represents significant surplus summer months dearth winter months. Effective needed solve problem. At present, best candidates TCES. Both sorption reaction present many interesting chemical pairings optimise various different important parameters, including: Energy density, cycle stability, turning temperature, capital running costs, power output, charging discharging speed. due hazardous high temperatures chemicals associated with based TCES, it can be all but ruled out from application. Sorption TCES presents promising subcategories, salt composite materials emerging most likely category succeed market. faces key though, its output. Fluidised bed reactors (FBRs), both bubbling fluidised beds circulating beds, been used extensively industry increase mass transfer industrial processes. They context assist concentrating plant systems. And, they shown effectively improve output systems, well other temperature systems (sensible storage, phase-change storage). Overall, clear FBRs potential applied priming applications. It also worth noting very few studies exist investigating there limited knowledge understanding how will affect • Domestic system density lack huge promise storage. not investigated Novel reactor types could vastly
