Dutch power rental company Bredenoord has launched a hybrid diesel-battery genset, Esaver, which it claims offers fuel savings of up to 40%.
The ESaver is a 400 V battery pack which, when combined with a standard 15 kVA genset, will provide a maximum output of 30 kVA.
The battery pack, which is in a separate enclosure and linked to one of Bredenoord’s standard rental gensets, provides power when charged and is recharged when the diesel genset resumes operation. The generator will only operate at its optimal rating, which also increases fuel efficiency, it says.
Bredenoord will offer customers an online system to monitor the operation of the hybrid unit, showing how much fuel is being saved over traditional alternatives. The Esaver unit weighs 1450 kg and is 2.33 m high, 1.2 m wide and 0.8 m deep, and uses a 48 V – 660 Ah battery pack.
