Off grid steam powered generator

Its slowly coming together

 

Below is the link to the prototype of the pellet boiler, still not allowed to show the CHP unit

As you will see, the boiler is designed to run on torrefied wood pellets (Biocoal)

These are a more efficient product than conventional wood pellets.

White pellets 4800kWh/kg 4.4 - 4.8p/kWh

Biocoal Pellets 6900kWh/kg 3.6 - 3.8p/kWh

The boiler is far more efficient than existing pellet boilers and has far fewer parts.

 

Hope to be selling the boilers and the fuel for next winter in East Anglia

How come it's cheaper running on biochar?

Seems odd that another level of processing makes it cheaper.

Point of order; Peter Read coined the word biochar for char used as a soil amendment and to sequester recalcitrant carbon for millennia as a means of removing excess CO2 from the atmosphere and surface waters of the sea. I think the reference was to biocoal burning in the stove.

Oops sorry. Misread woodworms post.

 

Think my question still stands though. Wood gets processed where I believe some of the volatiles are lost yet comes out cheaper than pellet

[woodworm]

Its because its not another level of processing, its a different method of processing which leaves no volatiles in the fuel. These are all utilised for process heat during the manufacturing process.

The fuel is therefore cleaner as there are no volatiles released during combustion.

The energy content of the fuel is at least 30% (can be up to 45%) greater than conventional pellets and we will base our pellet prices on energy content.

If we were to sell biocoal pellets at the same p/kWh price as white pellets (at £240/t), we would be looking at a much higher price and no benefit of making the fuel.

The pellets are also hydrophobic (Waterproof).

Looks like we will just about make it inside 12 months.

Hope to be able to announce something in the next 3-4 weeks.

Keep your eyes peeled Skyhuck

Will do

Take a look at the link below.

As promised the tech is almost here, not long to wait now.

We almost made it within the 12 months Skyhuck!

 

The future of energy has almost arrived.

Watching with great interest.

Not long to wait now. Looking forward to hearing more.
