The Scottish Government has committed to almost complete decarbonisation of the road transport sector by 2050.
Switched on Scotland
Switched On Scotland: A Roadmap to Widespread Adoption of Plug-in Vehicles sets out a vision that Scotland's towns, cities and communities will be free from the damaging effects of petrol and diesel vehicles by 2050.
The report was developed by the Scottish Government in partnership with experts from industry, academia and environmental bodies.
The roadmap outlines our plan to drive forward the uptake of electric vehicles in Scotland and was published on 12 September 2013.
Analysis is presented which illustrates that electric and plug-in hybrid electric vehicles (EVs /PHEVs) will make a substantial contribution to this ambition.
This will be motivated by Scotland's world-leading climate change targets and commitments to improve local air quality and noise pollution. The potential economic opportunities and the contribution of plug-in vehicles to Scotland's renewable energy targets are also recognised.
Switched on Scotland refresh
Recognising the rapid pace of change in technologies and markets for plug-in vehicles, the Switched On Scotland Roadmap includes a commitment to review early progress and identify any areas in which further action is required.
As a first phase in this process, Transport Scotland published a Roadmap Review on 7 November 2016. The Review takes a detailed look at progress since 2013, against the goals and actions contained in the Roadmap.
The Review is also being used to help inform engagement and consultation with the E-cosse plug-in vehicle partnership, which comprises more than 150 different organisations. The outcomes of this engagement will feed into the development of a refreshed plug-in vehicle action plan, which will be published by Spring 2017.

Electric vehicles & energy systems
A key goal identified in the Switched On Scotland Electric Vehicle Roadmap is to ensure that as an increasing number of electric and plug-in hybrid vehicles enter the market, the electricity grid is sufficiently robust and well-managed to accommodate any changes in demand. A further key opportunity is to fully realise the potential of plug-in vehicles to support the development of a cleaner and smarter energy system.
Transport Scotland, working with Urban Foresight, has therefore undertaken research to review the interaction between energy systems and electrified road transport. This supports the Scottish Government’s twin ambitions of encouraging widespread adoption of plug-in vehicles and developing a secure, sustainable and affordable electricity grid.
A report summarising the findings of this research is published on 28th July 2016 and is available to download. The report draws on desk research, interviews and findings from two workshops that brought together over 30 participants from across the public and private sector.
The report will feed directly into the Scottish Government’s development of a new Scottish Energy Strategy (due for publication in summer 2017) and Transport Scotland’s refresh of the Switched On Scotland Roadmap (due to be published early 2017). Continued engagement with stakeholders will be vital as we move forward.
The E-cosse partnership played a key role in the development of the Switched On Scotland report. Launched in March 2012, the partnership consists of the Scottish Government along with experts from industry, academia, environmental bodies and local authorities.

Advice on Low Carbon Vehicles
Choosing the right vehicle and driving in the most economical way can make a significant reduction in the level of emissions from transport.
Low carbon vehicles (LCVs), more efficient vehicle engines and alternatively fuelled vehicles can also help reduce transport sector carbon emissions.
Visit Greener Scotland for more information on electric cars and details on how to arrange a test drive.
Information on buying an efficient car, eco driving and energy saving tips can also be found at the Energy Saving Trust.
Electric vehicle grants for motorists
Motorists purchasing a qualifying ultra-low emission vehicle can receive a grant towards the cost from the UK Government, up to a maximum of £4,500.
Where can I charge my electric vehicle?
The Scottish Government has established ChargePlace Scotland – a network of charging points across the country. The network currently comprises over 600 publicly available charge points and is operated by Charge Your Car (CYC) Ltd.

Hydrogen and fuel cell technology
Hydrogen fuel cells combine compressed hydrogen with oxygen (from the air) to produce electricity. They can be used to power electric vehicles – either as the primary power source, or as a battery range extender, with the only tailpipe emission being water vapour. Fuel cells should be seen as a complementary technology to batteries as both are likely to play a part in the transport sector’s decarbonisation.
Transport is not the only sector where hydrogen is a useful resource. It can be used for heating and power applications and as a feedstock for chemicals production, such as fertiliser for agriculture. In future, we expect to see combined uses within projects that have multiple benefits for the environment and local communities.
Hydrogen can be made from natural gas or other fossil fuels, but if it is made from sustainable sources, (such as biogas, or by using renewable energy to “split” water molecules into hydrogen and oxygen gases), then the production process is also very green. In fact, the creation of hydrogen using Scotland's plentiful renewable resources will also be hugely beneficial to the energy sector as a means of storing renewable energy and helping to balance demand on the grid. Hydrogen can be stored indefinitely in compressed form. It can be transported from the point of production to the point of use in “tube trailer” trucks, or piped just like our natural gas supply. In fact hydrogen may be injected into the existing gas grid in future – helping to increase the decarbonise it, whilst also increasing its domestically sourced content.
Hydrogen fuel cell vehicles (HFCEVs) have a far greater range than most of today’s pure battery EVs. They can also be refuelled in a similar time to a petrol or diesel vehicle. However hydrogen is not limited to fuel cells…it can also be burned in specially converted petrol and diesel engines again producing mainly water vapour The lack of an existing nationwide refuelling infrastructure is currently a barrier to hydrogen vehicle use, but roll-out of refuelling stations will need to be carefully matched to need.
HFCEVs are available to buy right now, with a small number of car, light van, and bus types on offer. Several large car manufacturers will be launching HFCEV models in the coming months. These currently come at a high price premium, but volume production should see price reductions. Significant developments in refuelling infrastructure will also be required to support their wider introduction, but some exciting developments are already underway in Scotland:
Aberdeen is leading the way with a green production and refuelling station already up and running (since early 2015), with a second one due to be operational in mid-2016. The city also has a fleet of hydrogen-fuelled vehicles, including buses, light vans, and (in a world first), HFCEVs will soon be available to the public to drive, through the city’s “Co Wheels” car club.
Fife will soon be “joining the club” – with a hydrogen refuelling station directly connected to a wind turbine at the Levenmouth Community Energy Project. This will power a fleet of low emission vehicles for use by the council and community groups, including a pair of hydrogen fuelled refuse trucks - another world first for Scotland.
Orkney’s “Surf and Turf” project will soon see hydrogen produced on the islands from surplus wind generation capacity, with it being used to power vessels in Kirkwall harbour. In future this facility could be evolved to include hydrogen road vehicles.
Transport Scotland works closely with the Scottish Government’s renewable energy team and also the Scottish and Highland & Islands Enterprise agencies, to support and fund the introduction of hydrogen technology – in projects such as those mentioned above. Transport Scotland is also an active member of several groups and projects at both UK and EU levels, sharing knowledge, expertise and emerging research findings on hydrogen`s potential in transport.
Biofuels and other alternative fuels
Biofuels are fuels produced from a range of organic material – they can be both liquids and gases and can be used in wider applications than transport, primarily heating and power generation. Sustainable biofuels are derived from waste streams such as animal tallow or used cooking oil, with novel sources such as seaweed or algae also being researched.
Many biofuels are produced from crops such as wheat, maize, rapeseed, or sugar cane. However, the need to grow these crops can have unwanted effects in agriculture that undermine the carbon benefits and lead to food price rises. The main fuels currently in use in Scotland are bio-ethanol and bio-diesel. These are blended into most standard fuel in small percentages.
The increased use of alternative fuels will help reduce the carbon footprint of petrol and diesel fuelled vehicles and improve local air quality. Some alternative fuels, such as biodiesel from waste oils are well understood, but others involve relatively new and complex technologies to create synthetic fuels. These require further research and development before their uptake can be accelerated.
Transport Scotland is working with Scottish Enterprise and Zero Waste Scotland in funding the Scottish Biofuel Programme, which offers expert advice and support to companies in the sector in Scotland.
