WP1 Integrated Electrical Heat - Integrated Electric Heat - Domestic Heat Storage: A Landscape Review
Abstract:
The Integrated Electric Heating Project provided a modelling tool to evaluate the opportunities and challenges for electric heating to meet UK household requirements. The tool will be used to create and evaluate upgrade pathways for a small number of housing archetypes informed by detailed information gathered from dwelling participating in the recent Home Energy Management System trial.
This report contains a landscape review of domestic heat storage, produced by NEF, is included as an annex to the final report of the Integrated Electric Heat project.
We looked in detail at 13 technologies that could provide the necessary thermal storage. We considered both daily storage (energy stored and used within the a 24 hour period), and also seasonal storage (energy stored in summer to be used in winter). We also considered which technologies were appropriate for which heat sources and delivery mechanisms – like radiators, underfloor heating, or warm-air heating. We concluded that the most promising four technologies to pursue in the integrated electric heating project are:
- Phase-change materials in a storage unit – using the Sunamp or other system to provide storage over a day or a few days.
- A seasonal storage pit – using solar thermal energy to store energy from summer to winter.
- Electric storage heaters – powered by excess solar PV and cheap Economy 7 electricity overnight.
- A thermochemical system – included for its potential as a disruptive technology, which may need a buffer tank until system designs are refined
