• What are the environmental impacts of wood terminal equipmenttoday?‒ Focus on fuel consumption and emissions to air

• What kind of alternative (hybrid/electric) solutions‒ Are already on the market?‒ Have been recently studied or tested?

• What is the potential of the new solutions to decreaseenvironmental impacts?

Electric material handlers


• Electric material handlers are provided in different size classes and by several manufacturers (for example Mantsinen, Liebherr, Sennebogen)

• In Finland, electric material handlers are used at the major paper and paper mills and are the only fully electric equipment being used in wood handling

• In Sweden, an electric material handler is used for energy wood handling at Port of Stora Vika(Enström 2015)

• Hybrid material handler byTerex‒ launched in 2013 ‒ Available in 33–37,8 ton

equipment‒ Even up to 30 % saving in fuel

consumption

• Hybrid solutions available alsoby Sennebogen

• Hybrid wheel loaders are being manufactured by different companies (for example Volvo, John Deere and Parker).

• Volvo claims that its recently launched prototype (LX1) can bring fuel savings up to 50 %. This prototype is not yet commercially available.

• No hybrid log stackers?

• Electric chippers are common at pulp mills• Electric crushers are getting more common at the heat and power plants • Electrically powered, stationary crushers and chippers are in use in some

major energy wood terminals• In smaller terminals, only diesel-powered equipment is used (Impola &

Tiihonen 2011)

• KESLA’s full hybrid chipper is the first of its kind in the world

• The prototype was studied in theINFRES project (Laitila et al 2015)

• When compared to a traditional chipper, the fuel consumption was ‒ 3,1 l / 1 000 kg (6 %) less in chipping

of pulpwood‒ 2,9 l / 1 000 kg (26 %) less in chipping

of logging residues

• Hybrid shunting locomotives are being manufactured be several companies and they claim substantial fuel consumption savings (Konarzewski 2013):‒ Railpower (Canada) 40–70 % saving in

fuel consumption‒ Toshiba (Japan) 36 % fuel saving ‒ Alstom (Germany) prototype 40 %

fuel saving• The rail companies are also

increasingly interested in converting existing locomotives to hybrid.

• Electric shunting locomotive was studied by Molineri (2016). The analyses showed that hybrid locomotives are more feasible.

• In Germany, the world’s first hydrogen-powered passenger train will start operating in 2017.

• In Central Sweden, a pilot project is studying environmental impacts of hybrid trucks that are fully electric whenconnected to overhead power lines. (Region Gävleborg 2016)

• Two kilometers of power lines havebeen installed above the Motorway E16

• Partners in the project are for exampleSiemens, Scania and Stora Enso.

• Hybrid trucks are also manufactured byNikola Motors and Terberg.

• A simulation study carried out at Aalto University (Lajunen 2014)‒ Estimated fuel consumption (l/tkm) of electric wood trucks (90 tonner and

40 tonner) ‒ 3 different battery options and 5 route types were compared‒ Hybridization seemed to be more advantageous on routes with substantial

amount of hill climbing‒ In average, 3 % saving in fuel consumption was discovered
