The US Department of Energy (DoE) is to provide $20 million (£15.47m) of funding across 10 low carbon transport and fuel projects.
The move completes the approval process for awardees selected by Advanced Research Projects Agency-Energy (ARPA-E).
They form part of the organisation’s Next-Generation Energy Technologies for Connected and Autonomous On-Road Vehicles (NEXTCAR) and Renewable Energy to Fuels Through Utilisation of Energy-Dense Liquids (REFUEL) programmes.
The NEXTCAR project at the Southwest Research Institute in Texas aims to work towards the department’s goal of reducing individual vehicle energy usage by 20% by modelling controls for efficient vehicles equipped with 12 volt micro-hybrid engines.
It will receive $2.9 million (£2.24m) in funding.
The nine REFUEL projects aim to use water, air and renewable power to produce liquid fuels for transportation and other purposes.
The EU is mobilising €1 billion (£850m) to leverage private investment in green transport infrastructure.
