The Innovations Pushing Transport Toward Net-Zero

The global transport infrastructure is deeply intertwined with the fossil fuel industry. Transportation contributes 15% of global emissions, making it the second-largest emitter of greenhouse gases. To achieve transport decarbonization, the sector must wean itself off fossil fuels which still powers most vehicles worldwide.

 

There are promising signs of progress.. The electrification of road transport is accelerating, with advancements in electric vehicles and batteries leading the way. However, other transport segments—public transit, freight, aviation, and maritime—still have a long road ahead. Decarbonizing long-distance transport remains one of the toughest challenges.

 

To cut emissions, the transport sector must immediately improve energy efficiency across all modes and expand the use of low-carbon fuels. Yet, progress is hindered by declining investment. Climate Tech funding for transport has steadily decreased, from 22.3% of total Climate Tech funding in 2020 to 19.1% in 2024. Achieving deep emissions reductions will require significant infrastructure investments to enable low- and zero-emission transport solutions at scale.

Electric Vehicles

 

The electrification of road vehicles via EVs is a game-changer for the transport sector. EVs allow the industry to integrate clean energy sources and reduce dependence on fossil fuels. EV adoption is growing strong, with global sales surpassing 10 million in 2022, accounting for 14% of all car sales.

 

Some of the key Climate Tech innovations in road transport electrification include:

  • EV Manufacturing – Advanced battery technologies increase energy density and charging speeds, while automated production and lightweight materials improve efficiency.
  • Electric Air Transport – eVTOLs (electric vertical take-off and landing) and electric aircraft reduce aviation emissions, making urban air mobility and short-haul flights more sustainable.
  • Electric Trucks – Battery-electric models dominate short- and mid-range transport, while hydrogen-powered trucks enable longer distances with fast refueling.
  • Electric Scooters – Compact and powered by electric motors, they offer a zero-emission solution for urban commuters and short-distance travel.
  • Electric Vessels – Ships and boats run on electric propulsion, using high-capacity batteries and efficient motors to cut maritime emissions.

Charging Stations

 

Charging stations serve as critical infrastructure for the shift to cleaner transportation, supporting both electric vehicles (EVs) and alternative fuels. While traditional EV charging points dominate, many stations accommodate compressed natural gas (CNG) and liquefied natural gas (LNG) too. Hydrogen fuel stations further strengthen the ecosystem by enabling zero-emission fuel cell vehicles with quick refueling capabilities.

 

Despite rising EV sales, charging infrastructure has not kept pace. A reliable and widely accessible network is essential to ease range anxiety, improve user convenience, and support long-distance travel. Charging must also integrate seamlessly into daily life—at home, workplaces, and public locations.

 

Advancements in EV charging focus on speed, flexibility, infrastructure management, and user experience. Key innovations include:

  • EV Charging Technology – Faster charging speeds, smart energy management, and improved grid stability through innovations like ultra-fast charging, wireless charging, and vehicle-to-grid (V2G) solutions.
  • Hydrogen Fuel Stations – These refueling hubs enable hydrogen-powered vehicles to achieve long driving ranges with quick refueling, positioning hydrogen as a strong contender in clean transportation.
  • Charging Digitalization – Smart charging solutions, including dynamic load management and real-time pricing, optimize grid demand and improve cost efficiency.
  • EV Charging Financing – New business models like Charging-as-a-Service (CaaS) reduce upfront costs, making charging infrastructure more accessible for businesses and consumers.

Transport Fuels

 

The transport sector accounts for nearly 60% of global oil demand, and rising economic standards continue to drive consumption. However, long-term projections suggest a shift. The Global Energy Perspective 2023: Oil Outlook forecasts that oil demand will start to decline by year 2030. This trend is mostly driven by a decrease in fossil fuel-powered road transport, as more EVs hit the road. Given the scale of road transport, especially in remote regions, phasing out fossil-fueled vehicles must happen gradually.

 

Similarly, scaling low-emission fuels is necessary for high-energy sectors like aviation and maritime. Transitioning ships and planes to alternative fuels should help cut emissions.

 

Innovation in low-carbon fuels powers the shift to sustainable transport through solutions such as::

  • Biofuels produced from renewable sources like crops, algae, and waste materials provide a cleaner alternative to fossil fuels, helping to cut emissions.
  • Hydrogen is a fuel cell technology that delivers zero-emission energy with potential across multiple transport applications.
  • Synthetic Fuels are created through carbon capture and utilization and offer a scalable option to lower the carbon footprint of internal combustion engines.

 

Beyond fuel alternatives, improving fuel efficiency is an easy path to transport decarbonization. Advancements in vehicle technology optimize energy use and reduce fuel consumption. Key innovations include real-time traffic monitoring, fleet management systems, and next-generation engine designs.

Ports and Maritime Transport

 

The global economy is highly dependent on international shipping which facilitates nearly 90% of worldwide trade. However, it also accounts for 70% of global shipping-related energy emissions, making it one of the hardest sectors to decarbonize. Achieving net-zero emissions in maritime transport requires a strategic combination of energy efficiency improvements and a transition to renewable fuels.

 

Advancements in both container ships and port infrastructure are accelerating the shift toward maritime transport decarbonization. Innovations in container ships focus on reducing emissions, improving fuel efficiency, and integrating cleaner propulsion systems:

  • Advanced hull designs and propulsion systems enhance fuel efficiency by reducing drag and optimizing energy use.
  • Alternative fuels such as LNG, hybrid propulsion, and ammonia-based fuels offer lower-carbon solutions to power long-haul shipping.
  • Emissions capture and monitoring technologies enable real-time tracking of pollutants, helping ships comply with global environmental regulations.
  • Electric maritime transport utilizes battery-electric propulsion to cut emissions, particularly for short-distance ferries and smaller vessels.

 

In port infrastructure, key developments include the creation of charging and refueling stations for ships, implementation of smart port technologies, and optimization of maritime container operations. Some of the innovative solutions include:

  • Smart port technologies leverage IoT and AI to optimize logistics, minimize delays, and reduce fuel consumption.
  • Automated and remotely operated equipment improves efficiency, cutting turnaround times and operational costs.

 

Preserving marine ecosystems is essential to maintain coastal health. Marine environment remediation involves restoring polluted or damaged marine ecosystems to their natural state. Innovative solutions focus on pollution prevention and cleanup:

  • Ballast water treatment systems use filtration, UV radiation, or chemical disinfection to stop the spread of invasive species.
  • Oil spill management employs advanced techniques like bioremediation, where microorganisms break down oil, and deployment of oil-absorbing nanomaterials for rapid cleanup.
