Physical energy infrastructure / network concept

Charge here.
Use somewhere else.

A standardized carrier is designed to connect surplus, storage and demand across different places and owners. The carrier network comes first; any single application is just one job it can do.

Inventory opens possibilities.

A physical standard could separate who generates energy, who owns the carrier and where the energy is used.

A solar producer could charge carrier inventory owned by someone else.

Explore Fairlight Exchange ↗

Future operating concepts, not available services. Certification, settlement, safety and commercial viability remain to be established.

Surplus → preserved carrier → demand elsewhere

Industrial PV hub

Surplus production near a source of low-value or curtailed energy.

A proposed operating model. Fairlight Exchange is not yet a trading or transport service.

Value at destination>Energy loss + handling + transport

Moving energy only makes sense when the value exceeds the logistics. Fairlight is designed for local and regional exchange, not for replacing transmission lines with trucks.

  • 0–50 kmStrongest early exchange zone
  • 50–100 kmUse-case dependent
  • Long distanceOnly high-value applications

Economic development hypothesis—not a product limit.

01 / Utilization

Poor capital utilization

A seasonal-only carrier earns once, then waits. The processing asset and the inventory both sit idle.

An illustrative principle. Fairlight does not present a measured LCOS.

02 / Efficiency

~40–45% round-trip

Current published iron-air system evidence. The objective is to improve the complete system, not just one electrode step.

Fairlight system efficiency: not measured yet. No 80% is implied.

03 / Energy value

Go where the value is

Best early applications:

  • Curtailed commercial solar
  • Negative-price energy
  • Remote diesel displacement
  • Capacity and resilience
  • Grid constraints
  • Local exchange

Weak initial use case: pure one-cycle-per-year household arbitrage.

A seasonal battery that earns nothing the rest of the year is hard to finance.

That is why Fairlight is being designed as reusable energy inventory rather than a single-purpose household appliance.

One carrier.
Many jobs.

  1. 01

    Multi-day storage

    Commercial solar surplus today. Use later this week.

  2. 02

    Seasonal reserve

    Summer surplus. Winter demand.

  3. 03

    Local exchange

    Charge at one nearby site. Use at another.

  4. 04

    Resilience

    Stored reserve held for outages and emergencies.

  5. 05

    Remote power

    Displace expensive fuel or weak-grid supply.

Seasonal storage is a capability.
Not the only business model.

A carrier that only cycles once each year is difficult to justify economically. Fairlight is therefore being developed for long dormancy and useful operation throughout the year.
