Scottish Zero Emission Bus challenge fund

The aim of the Scottish Zero Emission Bus Challenge Fund (ScotZEB) is to support swift, and significant, change in the bus market in favour of zero-emission technologies. This will support the Scottish Government’s purpose to create sustainable and inclusive growth. In particular, the fund aims to support the National Outcomes relating to the Economy, the Environment, and Fair Work and Business.

By supporting the swift transition to zero emission vehicles and infrastructure, the fund will help to achieve targets to reduce greenhouse gas emissions, contribute to the delivery of Low Emission Zones, encourage inward investment and growth in the supply chain of zero carbon vehicle and energy solutions in Scotland, with associated employment, economic and social benefits.

ScotZEB is a new challenge fund focussed on supporting innovative business models designed around the characteristics and opportunities presented by zero-emission buses and associated charging or refuelling infrastructure. Bidders are strongly encouraged to put in place arrangements with partners or collaborators, to minimise the level of subsidy being requested. This may involve, for example:

  • collaborations across multiple bus operators to get the financial benefits of scaled demand for new buses
  • collaborations with non-bus vehicle operators or Local Authorities to get the benefits of scaled up demand for hydrogen
  • partnerships between energy companies, operators and financiers to use the charging infrastructure to generate new revenue streams
  • partnerships between financiers, manufacturers to purchase buses for leasing to operators
  • or a range of other possibilities

Phase 2

Phase 2 of ScotZEB, which opened to applications on 15 May 2023, is designed to provide capital funding to forward-thinking companies to disrupt the bus and coach market, and help make zero-emission vehicles the default choice for all operators from now on – that includes operators of public service buses, home-to-school buses, community buses, transport-to-health buses and tourist and private-hire coaches who can all potentially benefit. 

Effective private financing is key to making zero emission buses and coaches, and infrastructure, affordable to all operators. Financing that aggregates ownership to generate greater buying power, spreads the cost of these assets over their full useful lives, supports the transition of other transport operators and modes (such as goods vehicles, and vans), and transfers the risk and complexity of these assets from those operators who prefer not to deal with these issues are all essential considerations. Bids that provide solutions to these issues will be favoured. 

Who can apply to ScotZEB Phase 2

The following bodies will be eligible to bid for funding from ScotZEB Phase 2 as part of a consortium:

  • Financiers
  • Bus and coach operators, including home-to-school and tour coach operators
  • Community Transport Organisations
  • Original Equipment Manufacturers, including repowering companies
  • Infrastructure providers
  • Local authorities

Other bodies may also be eligible in addition to those listed above. For more information, please refer to the guidance available on the administrator’s website.

* This table shows the operators who have been offered awards. There are more operators than there were bidders, as all the bids from Stagecoach owned operators were treated as a single bid.

** A variety of bus sizes, from minibuses to double decks, are being supported. All awards also include support towards the charging infrastructure, in some cases the charging infrastructure will support a greater number of vehicles than the number of buses shown in the table.

*** The difference from the estimated costs to the final costs drawn down could be as a result of various factors, such as changes in cost, suppliers or withdrawal from the scheme.
