Under accelerated development

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
