Transport is the necessity of modern life, but it comes with a heavy cost. The sector accounts for ~25% of global CO₂ emissions—a figure expected to rise as economies grow and mobility demand increases, according to IEA. This growing ecological footprint is urging governments, automakers, and energy providers to embrace sustainable mobility solutions and take decisive action toward decarbonization.
Among the sustainable mobility solutions, electric vehicles (EVs), hydrogen-based systems, and synthetic fuels (eFuels) have been the front-runners in lowering emissions. The technologies that were once conceptual are now shaping trillion-dollar markets, propelled by stricter emissions standards, net-zero targets, and shifting consumer demands. The strategic approaches for enterprises and policymakers to achieve net-zero goals are clear. They need to determine which solutions to deploy, in which regions, and for which mobility segments.
Mapping the Mobility Market with Categorization
The sustainable mobility space has become quite complicated, with each technology having distinct advantages based on geography, infrastructure, and use case.
Electric Vehicles (EVs)
EVs are set to lead in the passenger cars segment, expecting ~50% of new sales by 2035. Advances in battery technology (250–400 Wh/kg) extend range (400–600 km), and fast charging (150–350 kW) reduces downtime. EVs are cost-efficient per kilometer, and thus are an optimal choice for urban and light-duty mobility.
Fuel Cell Electric Vehicles (FCEVs)
FCEVs are best suited for long-haul transportation, particularly heavy-duty vehicles, due to high energy density (~33 kWh/kg H₂), significantly short refueling time (10–15 minutes), and more than 600 km of range. This technology is majorly integrated in freight corridors, public transit, and logistics hubs, where the extensive weight of batteries and long charging time are the key hurdles.
Hydrogen Internal Combustion Engines (HICEs)
HICEs are an in-transit solution where green hydrogen is abundant, but fuel cell infrastructure is lacking. While less efficient (~30–40% vs. ~60% for fuel cells), they leverage existing ICE platforms for quicker decarbonization of legacy fleets.
eFuels
eFuels are derived from CO₂ and renewable electricity, aiming to decarbonize the heavy emissions sectors, foremost among those being aviation & shipping. Fully compatible with existing engines and supply chains, they have near-zero emissions over their lifecycle. While production based on the current technologies remains expensive ($3–5/L), mandates and economies of scale promise to make eFuels more competitive.
Core Levers of Mobility Adoption
The pace of sustainable mobility adoption depends on four interlinked levers:
- Technology Performance – Advances in batteries, hydrogen systems, and synthetic fuels set the limits on range, refueling time, and reliability across use cases.
- Economics of Scale – Cost competitiveness hinges on scaling production—whether through battery gigafactories, hydrogen hubs, or eFuel plants.
- Ecosystem Infrastructure – Charging networks, refueling stations, and renewable integration define how quickly technologies can move from pilots to mass deployment.
- Policy & Regulation – Emission caps, fleet targets, and carbon pricing remain the strongest accelerators, shaping where capital and infrastructure are deployed.
How Geographies Are Driving Adoption (With Regulatory Influence)
Adoption of sustainable mobility varies by region, shaped by infrastructure, energy mix, and regulatory frameworks:
- Europe: EV penetration in the region has been gaining momentum (20%+ of new sales in 2023), driven by an ICE ban from 2035, more than 550,000 public chargers, and incentives. Hydrogen corridors for trucks are under development, and binding eFuel blending mandates are framing OEM plans.

- China: The world’s largest EV market with 60% of global EV sales share in 2023, supported by 1.8Mn public charging points and dominance in battery supply chains. EV subsidies and New Energy Vehicles (NEV) policies reinforce adoption, while FCEVs are piloted in freight and port operations.

- United States: EV adoption is skyrocketing (9% of new sales in 2023) due to IRA subsidies. A multibillion-dollar investment in hydrogen hubs positions the U.S. at the global forefront of green hydrogen for freight transportation and heavy-duty transportation
- Japan & South Korea: Early leaders in hydrogen transportation, with Japan aiming to establish more than 900 H₂ stations by 2030 and South Korea plans to have 30% of its buses run on hydrogen by 2035. National hydrogen targets and refueling mandates support industrial and logistics centers, while EV adoption remains steady but secondary.
- India: The country is projected to hold 30% of the global EV market share by 2030, with incentives for two- and three-wheelers driving early adoption. The National Green Hydrogen Mission and PM E-Drive scheme are collaboratively contributing to driving hydrogen and EV deployment.
- Middle East & Australia: Both regions prioritize hydrogen. Australia is deploying freight corridors, while Saudi Arabia’s NEOM project positions the region as a major green hydrogen producer.
Challenges in Sustainable Mobility: Overcoming Critical Barriers
Sustainable transport transition still encounters countless daunting challenges to provide a greener future. Infrastructure gaps remain one of these challenges, as EV charging infrastructure continues to expand rapidly while hydrogen refueling stations remain scarce—especially in critical long-distance freight corridors. Large-scale synthetic eFuels adoption also relies on large-scale renewable electricity production and CO₂ capture facility investments, necessitating cross-sector investments to keep pace. Unpredictable supply and prices of critical battery materials like lithium, cobalt, and nickel also continue to reduce EV affordability, as hydrogen production and storage technologies remain expensive and energetically intensive.
Policy and regulatory differences at regional levels cause uncertainty, delaying adoption timelines and infrastructure development, and posing planning challenges to both investors and manufacturers. On the consumption side, lingering range anxiety, refueling inconvenience, high purchase prices, and low awareness keep market uptake sluggish. End local cultural and travel behaviors, also highlighting challenges in untangling these interrelated difficulties.

Strategic Opportunities: Pathways to Accelerate Adoption
Despite these hurdles, ample strategic opportunities exist to accelerate the adoption of sustainable mobility solutions. Expanding EV charging infrastructure alongside increased deployment of hydrogen refueling stations is key, supported by targeted investments that integrate renewable energy production with carbon capture to enable eFuels. Securing stable supply chains for battery materials, advancing hydrogen technologies, and scaling eFuel manufacturing are crucial to reducing costs and enhancing commercial viability.
Additionally, policymakers can play a pivotal role by harmonizing emissions standards, subsidy programs, and carbon pricing—providing clarity and stability that de-risks investments and accelerates infrastructure deployment. On the consumer side, comprehensive education campaigns, improvements in charging and refueling convenience, and diversified vehicle offerings tailored to market-specific preferences can effectively address range anxiety and cost concerns. By leveraging these opportunities through cross-sector collaboration and innovation, stakeholders can overcome existing barriers and drive the transformation towards a sustainable, resilient mobility ecosystem.
