Hemp farms: honest about drying and decortication

Industrial hemp is harvested fast and must be dried quickly to avoid mould. Some of that fits a stored hydrogen system. A lot of it does not.

The big loads are too big

Hemp grown for fibre goes through decortication, which strips fibre from the hurd with heavy machinery. Hemp grown for seed or flower needs drying soon after harvest, often in large belt or batch dryers with big fans and heaters. Both draw far more than 15 kW. Running them from hydrogen at round-trip efficiency of 30% or less would not make sense, even in a multi-unit setup. If your question is whether this can run a decorticator, the answer is no.

What it would keep running

  • Small drying room dehumidifiers
  • Drying room fans and controller
  • Seed storage cool room
  • Farm office and security

Where it does fit

Smaller hemp operations often dry seed or flower in a dedicated drying room with dehumidifiers, fans and a controller. Those can fit within 15 kW continuous. Seed storage needs cool, dry conditions, and a small cool room or dehumidified store fits well. The farm office, testing equipment and security systems are small loads that matter. A UPS-mode inverter keeps controllers from resetting, and the fuel cell runs from hydrogen stored at 30 bar or less.

How it works →
The H2OME loop: an electrolyser splits water into hydrogen, the hydrogen is stored in a tank for weeks, a fuel cell turns it into electricity for your home, and the water returns to the loop.

Planning for harvest

Hydrogen is made on off-peak power or wind before harvest and the store keeps for weeks. During harvest, it covers drying room controls and fans through outages so a batch does not sit damp and start to mould. The pilot would separate loads that fit from those that need a much larger supply, and say plainly which side your farm is on.

Questions

Can it run a hemp decorticator?

No. Decorticators are heavy industrial machines drawing far more than 15 kW. This system is designed for smaller loads like drying room controls, seed storage and the office, and we would say so plainly in a pilot.

What about a belt dryer?

Large belt dryers with heaters are also beyond one unit, and heat from hydrogen at 30% or less round-trip is costly. Small drying rooms with dehumidifiers are a better fit.

Will it keep seed storage dry in an outage?

Yes. A dehumidifier or small cool room fits within 15 kW, and the switch-over is instant, so seed stays in the right conditions through the outage. That protects germination and next season's planting.
