Fairlight energy carrier.Swiss development platform / FEC–1

Electricityyou can move.

Fairlight is developing a reusable physical carrier for stored renewable energy. Charge it. Store it. Move it. Use it elsewhere.

02 / Batteries stay put

Batteries stay put.
Fairlight doesn’t.

Most stored electricity is tied to the place where its battery is installed. Fairlight separates the energy inventory from the machine that charges and discharges it.

03 / One machine, many carriers

One machine.
Many carriers.

The entire architecture is three steps: charge the carrier, prepare it for storage, discharge it where it is needed.

One machine / development architecture

The expensive machine stays.
The energy inventory scales.

04 / Standardize the carrier

Standardize the carrier.
Improve what’s inside.

FEC-1 defines the physical interface: handling, docking, storage, identity and logistics. The electrode technology inside can improve without replacing the surrounding infrastructure.

05 / The payoff

Stored energy
becomes inventory.

The ambition is not another fixed battery. It is a common physical format for stored electricity.

Proposed future operating models
Now we prove it.
  1. Energy density

    Can a complete carrier exceed ~100 Wh/kg?

  2. Efficiency

    Can the full system reach ~40% or better?

  3. Dormancy

    Can useful energy survive months of storage?

  4. Cost

    Can the carrier become cheap enough to scale?
