By Nick Carey LONDON (Reuters) -Daimler Truck aims to cut costs and boost profit across all regions by 2025 as it goes "all in" for electric and hydrogen fuel cell powered vehicles, the world's largest truck and bus maker said on Thursday. German carmaker Daimler plans to spin off Daimler Truck later this year as it seeks to increase its investor appeal as a focused electric, luxury car business. "Both technologies (electric and hydrogen) will be needed," Daimler Truck CEO Martin Daum told an investor presentation on Thursday. "And we intend to lead the way in both technologies." Daimler Truck said zero-emission vehicles should make up 60% of its sales by 2030 and 100% of sales by 2039. As truck makers move towards a zero-emission world - and their hitting sustainability targets becomes more important for their customers - electric trucks are expected to be used for shorter distances, but the batteries needed for longer journeys would be too heavy and hydrogen fuel cells will need to be used instead.
