I'm intrigued. Don't know how the Kommune system works but I'd assume someone with clout on the committee got a bee in their bonnet, without thinking it through. This kind of thing isn't normal in Norway, right?

  
Oslo Kommune has very green initiatives.  Probably written by people with no knowledge of practical applications.

 

For example, the contract went out for the Oslo Kommune tree contract.  The city was split east and west.

 

The tender and eventual winner was to use all electric tools for works on the trees.  Including the chippers and larger chip trucks.  Electric powered 7.5 ton tippers didn’t exist at that time.  The tech wasn’t there on the batteries.  Chippers were next to useless.

 

I guess they were trying to attain the highest level of Greenism and worked back from there with feasible options.

Ah, so a big battery. 3,072Wh, does that mean it can produce 3 kilowatts for an hour?

Yes just about but you musn't discharge below 10%, 15% to be sure, so knock 10 minutes off.

A suppose being  4 stoke a genny is less polluting than a 2 stroke and it might  it also burn less fuel overall to do the same job...?

 

 

 

TP  have made a electric chipper says its can run 5hrs looks very slow though

Same with the vehicles.  Elctric cars everywhere, superb charging network and there “used” to be concessions for el car owners.  Such as zero vat, use of buss and taxi lanes etc.  they have slowly relinquished those now.

 

My own thought on this…. In order to compensate for the huge amount of fossil fuels the Norwegian Industries (Oil/gas) require to refine they have such green initiatives to reduce the Carbon Footprint.

I think it was a TP that the Kommune delivered to my mate for the Oslo job.

 

I didn’t hear good reports back.

I like the idea of this mini one thats  truck  mounted  🙂

Having a herd goats/sheep about to recycle  the suitable species of clippings also that would  be the extra eco icing on the cake.

 

 

 

 

Kommune should specify only plant goat friendly species!

Yes but the difference is gnat's piss in the scheme of things. I think a 4 stroke small liquid cooled engine running a DC charger at constant optimum power into a battery would be more efficient than running a flywheel and its fan at constant speed but it would need a rethink of how it chipped and probably load. I expect all the chipper firms will be investigating, hey @PeteB?

I see, advertised here, that Timberwolf have a hybrid with a small engine (beneath the size needing pollution controls??) that stores power produced at high idle, between chipping, into super capacitors which then feed an electric motor to increase power on demand. What they don't mention is the energy capacity of the system and how long the assistance is available before recharging.

Now that sounds like a good idea. Worth trying anyway.

If my memory is correct, the TW gives you 20 seconds of 25hp diesel followed by 20seconds of 60hp combined. The pack is estimated to be good for a million cycles. 

 

Greenmech did an electric CS100 some years back and did look at an electric Evo165. The battery supply was questionable and the cost was quiet prohibitive too. We shelved it as we are Tier 5 compliant with the petrol and diesel units we make. Demand or at least, requests from customers, was pointing out that electric would be a vanity build more than a business/financial success.
