Engineering, energy intelligence and investment support for fleet, rail, depot and logistics systems where uptime, infrastructure and energy demand must work together.
Fleet efficiency depends on vehicles, routes, driving patterns, charging or fuelling, maintenance and the buildings and depots that support operation.
Rail and logistics systems add stations, warehouses, workshops, traction or charging infrastructure and tightly controlled service schedules.
Zerith builds an evidence-led view across vehicles, sites and infrastructure so operators can reduce cost, manage capacity and plan investment without weakening service reliability.
Routes, payload, weather, congestion and driver behaviour influence vehicle energy use and the conditions behind each journey.
Warehouses, workshops, stations and depots add HVAC, lighting, process and out-of-hours demand alongside transport loads.
Charging, electrical distribution, maintenance windows and resilience need to align with operational schedules and future plans.
What drives the cost: select a factor to explore how it affects energy demand, capacity and operational decisions.
Zerith combines energy data, operational context and engineering review to identify measures that improve efficiency without obstructing service delivery.
Establish a useful baseline across vehicle groups and operating conditions so performance can be understood in context.
The question: how does energy use change by duty, route and vehicle?The aim is a prioritised programme of low-risk operational improvements, planned upgrades and longer-term investment decisions.

Zerith assessed operational requirements and compared electric, hydrogen-based and drop-in sustainable fuel options against real-world use, infrastructure constraints and long-term viability.
Yes. The scope can combine fleet or rail energy with depots, stations, warehouses, workshops and associated infrastructure.
Yes. Zerith can review demand profiles, diversity, maximum demand, electrical capacity, charging strategy and investment phasing.
Performance can be normalised using distance, payload, duty cycle, operating hours, vehicle type and other relevant variables.
Yes. Availability, maintenance, operating windows and resilience are treated as core design constraints.
Yes. Roadmaps can coordinate vehicle replacement, infrastructure, energy supply, operational change, cost, carbon and programme risk.
