Project Title

ROBUST (Electric shaRed mOBility hUbS Trials)

From

2023

2027

Summary

The project proposes a long-term mobility hubs trial in four urban locations in Ireland, Galway, Sligo, Donegal, and Dublin. The installed hub infrastructure will comprise e-car charge points, electric vehicles and e-bikes (provided by partners ESB & Enterprise) and further expand the offer of micro-mobility options. The mobility hubs show evidence of being an effective intervention to change travel behaviours and the ROBUST project will seek to develop an evidence-informed toolkit for mobility hub deployment. The 2-year trial will provide an opportunity to study the persistence of modal shift. The hub will serve as an incubator, accelerating the uptake of electric mobility options by allowing interacting with future mobility technologies and removing barriers through participatory research. Various stakeholders will be engaged in the process of hub evolution through stakeholder workshops and co-creation workshops. The project will use an experimental design comparing prior-to-trial travel behaviour, engagement with the hub modal options and after-trial persistence of the modal shift.

TRACT: TRAnsport Behaviour Change Trials

From

2022

2025

Summary

TRACT has two distinctive trials, one which will focus on the transition to electric vehicles (EVs) and the second using the mobility hub concept to encourage modal shift. The e-mobility trial will consist of a TRACT smartphone app that will be developed to inform users about their driving behaviour and the impact of switching to an electric vehicle. Several specific use cases will be examined (those without driveways, taxi drivers, rural groups) to determine what would encourage them to switch. The mobility-hub trial will combine the use of shared bikes, cars, active modes and public transport. A suburban location will be selected, and shared cars and bikes (provided by partners Yuko & BleeperBike) will be located there, advertised and promoted to the community. This model has been shown to reduce car ownership and emissions internationally. The 18-month trial will enable the TRACT researchers to measure the impacts of these interventions. The results from the trials will be extrapolated to the wider population to demonstrate what the potential emissions reduction could be in similar areas and user groups. A cost-effectiveness analysis, looking at wider economic benefits, will also be conducted at several stages of the project to feed into policymakers and inform local and national policy.

Project Title

Irish Car Stock Model (RATE)

From

Summary

In transport emissions modelling is a process that uses a lot of data. The accuracy of this modelling process is very much dependant on the quality of the base data used in this process. In 2019, it was estimated that 74% of trips in Ireland were made by private car. This demonstrates the importance of having an accurate car stock model. The RATE project will develop a sophisticated national car stock model that will incorporate purchasing preferences with historical data to provide a state-of-the-art national car stock model. The 2023 Climate Action plan places aims to decrease transport emissions in Ireland by 50% compared to 2018 levels. The policy uses the Avoid-Shift-Improve paradigm and under the improve section it is planned to sell 845,000 private electric cars. The improve section of the plan is responsible for removing 4.74 MtCO2eq and is the largest policy tool in the transport sector accounting for 43% of all emissions in the sector. Given the importance and the amount of emissions required to be reduced by this policy, it is vital to have the most up-to-date tools to monitor the success and project future trends. That is what is planned in the RATE project. The RATE project will: - Provide realistic estimated of the potential growth of EVs in the Irish Market - Estimate the associated emissions reductions from EV growth - Model the changes in air quality indicators such as particulate matter and nitrogen dioxide - Build upon existing SEAI funded research projects

Project Title

CONUNDRUM - Co-Creating sustainable and shared community mobility

From

Summary

Tackling transport and mobility challenges is critical to addressing the climate crisis, given that transport emissions accounted for more than 20% of sectoral emissions in Ireland in 2020. A recent OECD (2022) report noted that current policies that aim to decarbonise the system via private vehicle improvements are `unlikely to lead to substantially different patterns of behaviour, rapid emissions reductions, and large well-being improvements'. A key challenge is how to move beyond a focus on private, electric mobility to engage with more radical low-carbon alternatives. Our team proposes to accelerate progress towards carbon emission reductions but also to actively enhance and sustain community wellbeing. The key objective here is to empower communities to adopt more sustainable modes of mobility by demonstrating how shared low-carbon transport can plug the gap when high frequency public transport might not be available. As well as addressing carbon reduction targets, shared mobility could support community wealth building through the development of novel initiatives that address a community need and reconnect people to their place and each other, contributing to addressing the challenge of isolation that many more vulnerable communities feel post-Covid (Government of Ireland, 2021). Balancing climate action with social justice requires recognition that not all places are equal, with some smaller towns and rural areas facing much more challenging sustainability transitions. We will complete an initial mapping of key relevant stakeholders in each location, building on the existing work of TASC (our societal impact champion,) who have initiated some community engagement already around just transitions in Enniscorthy. We will then develop the SCOOT App using deep learning methods, behavioural tools and tailored information to enable the community to optimise modes of transport that reduce emissions and decrease travel costs and travel time. The third solution will see the amalgamation of the previous two solutions into one research activity, modelling how the potential change of transport modes impacts the south-eastern regional transport model developed by the National Transport Authority. The changes in mode preferences and the use of shared modes of transport will be modelled for the Enniscorthy area to determine how it affects travel times and emissions in the community.

POWERDRIVE

From

2022

2025

Summary

POWERDRIVE is submitted in framework of the Horizon Europe's Cluster 5 "Climate, Energy and Mobility" whose main focus is to "accelerate the twin green and digital transitions and associated transformation of our economy, industry and society with a view to achieving climate neutrality in Europe by 2050". To comply with the described policy framework and meet the work programme requirements and EU policy goals, POWERDRIVE aims at developing a next generation, highly efficient, cost-effective, and compact power electronics solution that integrate a portfolio of technologies for multi objective optimisation of electric powertrains of battery electric vehicles (BEV). These integrated solutions can be applied to both low-performance and high-performance vehicles, and they will be suitable for diverse types of electric vehicles (EV). The concept of POWERDRIVE is that all the experience and expertise of the project partners in the development of electric drivetrain components will be leveraged and lead into the integration of advanced power electronics solutions for an optimised powertrain. This concept brings additional opportunities to strengthen Europe's supply chain in electromobility for road transportation and to achieve zero-emission road mobility.
