Introduction
Purpose of this paper
The purpose of this paper is to provide the Taskforce with an overview of key elements of the vehicle supply chain and issues over the vehicle lifetime that are critical to HGV decarbonisation.
The HGV supply chain and use landscape can be considered as a number of stages from manufacture to end of life as presented in Figure 1 for HDVs.
This paper focuses on HGVs and covers the impact of producing Battery Electric Trucks (BETs) and Hydrogen Fuel Cell Trucks (FCETs) on:
the vehicle production process - the manufacture of parts, components, systems and fuels, vehicle manufacture and conversion; and
vehicle maintenance and end of life.
Implications for Scottish firms and institutions are also drawn out.
The focus of the paper is on the impact of shifting to ZETs on the vehicle supply chain rather than on current supply chain issues relating to other external factors.
The impact on skills will be covered in a separate paper by Transport Scotland.
The Taskforce is asked to consider how can we maximise the involvement of Scottish suppliers and Scottish R&D in the design and development of any trials.
Where do OEMs see most potential for Scottish firms adding value?
How can operators make best use of local expertise?
Definitions and assumptions
Four main types of vehicle powertrain technologies are expected to contribute to the pathway to zero emission trucks – Battery Electric Trucks (BETs), Hydrogen Fuel Cell Trucks (FCETs), Catenary Electric Trucks (CETs) and Low Carbon Fuels (LCFs). The literature review did not reveal information on the impact of CETs and LCFs so these technologies are not covered in this paper. In the case of CETs, effects on the vehicle supply chain are expected to be similar to BETs. LCFs are likely to require minor modifications when compared to BETs and FCETs.
The supply chain for ZET production is defined as follows (Based on definitions used in Optimat study):
OEMs – manufacturing and integrating different components and systems into the final vehicle;
Tier 1 suppliers – pr
