Episode notes

In this episode of Earthlings 2.0, we chat with Pieter Smit, Head of Global Sales at Wright Energy Storage Technologies (WEST), about how the company is redefining energy storage with supercapacitor-based systems. Unlike lithium-ion, WEST’s electrostatic storage delivers high efficiency, rapid charge cycles, and extreme durability — tested everywhere from Africa to North America With applications spanning homes, data centers, shipping, and utility-scale projects, WEST is positioning supercapacitors as a safer, longer-lasting, and more sustainable path “beyond lithium.”

Key Points:

Electrostatic Advantage – WEST’s supercapacitors store energy without the fire risks or chemical degradation associated with lithium-ion batteries.
Built to Last – The systems are designed for up to 45 years of operation and come with a 20-year warranty to ensure reliability.
Efficiency Edge – With 97% round-trip efficiency, nearly all the energy stored in the system can be recovered and used.
