Traditional Phase Change Material Plentigrade
Low thermal conductivity resulting in low power and inability
to accept and deliver heat from high flow rate hot water
✓Unprecedentedly high flow rate, high power hot water via
innovative design
Sub-cooling (failure to solidify–low energy release or output temperature)
✓Additives to the PCM and internal design of heat battery
eliminates sub-cooling
Unsustainable and scarce resources and materials (e.g., palm oil)✓Made from by-products of widely deployed industrial
processes (chlor-alkali, petro chemicals, brewing)
Toxic materials sometimes used (e.g., barium hydroxide and chlorates)
✓Non-toxic: Main components are found in food products
Often organic PCMs that are flammable and have volatile oil-
linked pricing
✓Based on inorganic salts: Non-flammable, pricing much lower
and stable
High cost of materials and devices (e.g., £5–10/kg PCM; batteries >$200+/KWh)
✓PCMs <£0.5/kg; complete heat batteries cost under $75/kWh
(Pathway to further 50% cost down)
Uncertain long-term compatibility with their local environment (corrosion uncertainties, permeability restrictions)
✓Strong focus on corrosion and permeability (water/oxygen
ingress), resulting in confidence in long lifetime
Usually fails in less than 100 cycles ✓Over 95% capacity remains after 40,000 accelerated cycles
