Solthera Technologies

🚀 From the Stars to the Suburbs

In the 1960s, as NASA prepared for human spaceflight, engineers faced a daunting challenge:
How do you regulate temperature in space, where there’s no atmosphere to insulate against extreme heat or cold?

Their answer wasn’t more electricity. It was smarter heat management.
They developed early versions of phase change materials (PCMs)—substances that absorb, store, and release heat during the process of changing state (from solid to liquid and back again).

What started as a solution for astronauts and satellites has now landed in our homes, buildings, and cities.

🧪 What Is PCM (Phase Change Material)?

PCMs are materials that store and release latent heat as they melt or freeze at a specific temperature.

Example:
A PCM with a melting point of 55°C (131°F) will:

Absorb heat as it melts—keeping surroundings cooler
Release heat as it solidifies—providing warmth on demand

This cycle can repeat thousands of times, making PCMs an efficient and reliable tool for managing temperature without using extra energy.

🔋 Solthera: Bringing Space-Age Materials Into Every Mechanical Room

Solthera’s thermal battery uses proprietary PCMs that melt and solidify at key setpoints to store thermal energy from:

Solar thermal systems
Electric or heat pump sources
Grid power during off-peak hours

Benefits of PCM-based storage over traditional water tanks or electric heaters:

✅ Higher energy density
✅ More compact design
✅ Zero energy loss during storage
✅ Long-term durability (>20 years)
✅ No moving parts or mechanical degradation

🏡 Why PCM Belongs in Modern Homes

Just like NASA used PCMs to balance temperature in space, Solthera uses them to balance energy in homes.

With volatile energy prices, increased demand for electrification, and tighter building codes, PCMs offer:

Load shifting: Store heat during low-cost hours, use it during peak demand
Grid resiliency: Reduce stress on infrastructure
Smart integration: Pair with solar, heat pumps, and radiant systems
Passive energy control: Thermal comfort with zero standby loss

🔄 From Cold Chain to Carbon Neutral

Today, PCMs are found in:

Shipping containers transporting COVID-19 vaccines
Emergency shelters in disaster zones
Data centers managing server heat loads
Clothing for elite athletes and military personnel
Your next home’s mechanical room

Solthera is proud to bring this high-performance material out of the lab and into everyday life—providing decarbonized heating that’s scalable, sustainable, and space-ready.

📡 A Future Built on Smarter Heat

PCMs are one of the few technologies that transcend sectors—from aerospace to agriculture to architecture.

Solthera is building on that legacy, putting the same space-tested material that once protected astronauts… into homes that now protect families from rising costs, climate instability, and grid failure.
