Sunamp is a thermal energy storage company headquartered in Edinburgh that has developed modular heat batteries for storing excess heat and electricity from renewable sources. Their core product is the Sunamp Heat Battery, which uses phase change materials to store and discharge heat energy at high power levels. Sunamp is seeking collaborations with Chinese companies in HVAC, energy, and automotive to refine their products for the Chinese market and expand their thermal energy storage solutions.

4. Core Development – Sunamp Heat Battery
Sunamp developed world’s first volume-production
heat battery (made in Sunamp own factory).
Sunamp Heat Battery is core Sunamp product:
• Modular – change shape and capacity
• Scalable – adapt to different installations
• High power – store or discharge heat energy at >35 kW
• Energy dense – 4x better than hot water, oil or glycol
• Advanced, Stable, Safe
• No Degradation – 22,000 cycle test completed
Based on Phase Change Material (PCM) developed in R&D
collaboration with University of Edinburgh.
Patents for materials, heat battery and applications
granted in U.K. and China. Pending in other countries.

8. Hybrid Bus:
• Not enough engine heat in
the morning to warm the
passengers = complaints
• Solution: Save waste heat
late in the day, charge into
heat batteries, store
overnight and use next
morning to heat the bus
Example product: Bus heating
Electric Bus:
• 30 – 50% range loss in
cold weather
• Current solution: Use
11kW diesel fuel heater
• Sunamp solution: Charge
heat battery straight after
the electric battery
finishes charging, use the
heat to warm the bus and
save the electric battery
for driving
