Ammonia (NH3) produced from renewable energy serves as a carbon-free maritime fuel that can reduce shipping emissions by 80-100% compared to heavy fuel oil while leveraging existing global ammonia distribution infrastructure. Green ammonia contains 18.6 MJ/kg energy density enabling long-distance shipping with fuel costs targeting $500-800 per ton. Companies like MAN Energy Solutions and Wärtsilä are developing ammonia engines with first commercial vessels planned for 2025-2027.
Hydrogen fuel cell trains provide zero-emission rail transportation with 400-1,000 km range and 160 km/h operating speeds, replacing diesel locomotives on non-electrified lines. These trains achieve 35-45% fuel cell efficiency with hydrogen consumption of 0.3-0.4 kg per km. Companies like Alstom and Siemens deploy commercial hydrogen trains with operating costs 10-20% higher than diesel but eliminating local emissions.
Electric Bus Rapid Transit (BRT) systems use dedicated lanes and electric buses to provide high-capacity urban transportation with 70-90% lower emissions than diesel buses. These systems can carry 20,000-35,000 passengers per hour per direction while reducing urban air pollution and noise. Cities like Bogotá and Istanbul operate large-scale electric BRT systems with total costs of $3-15 million per km including infrastructure.
Electric micromobility sharing systems including e-bikes, e-scooters, and e-mopeds provide sustainable urban transportation with 90% lower emissions than car trips for distances under 5 km. These systems serve 15-20% of urban trips in major cities with 400+ million rides globally in 2023. Companies like Lime, Bird, and Voi operate fleets with operational costs of $0.15-0.30 per km and user costs of $0.25-0.50 per minute.
Sustainable Aviation Fuels (SAF) produced from waste feedstocks including municipal solid waste, agricultural residues, and used cooking oil can reduce lifecycle carbon emissions by 50-80% compared to conventional jet fuel. These drop-in replacement fuels meet existing engine specifications while utilizing waste streams that would otherwise generate methane emissions. Companies like Fulcrum BioEnergy and Neste have commercial production facilities with costs targeting $3-4 per gallon.
Highly efficient electric rail transportation that is 6x more energy efficient than road transport, with high-speed rail reducing emissions by 80% vs aviation. Battery trains enable electrification of non-electrified lines.
Carbon-free marine fuels including green ammonia and methanol for decarbonizing shipping, which accounts for 3% of global CO2 emissions. Green methanol can reduce shipping emissions by 95% while meeting IMO 2050 targets.
Hydrogen fuel cell vehicles offering 300+ mile range with 5-minute refueling, optimal for long-haul heavy-duty transport. Green hydrogen production costs are falling rapidly, making hydrogen mobility increasingly viable for transportation applications.
Electric aviation uses battery-electric or hybrid-electric propulsion to reduce aviation emissions and noise. Electric aircraft range from small 2-seat trainer aircraft to 19-seat commuter planes, with companies like Eviation, Heart Aerospace, and Wright Electric developing commercial models. Current limitations include battery energy density and range, with most electric aircraft targeting short-haul flights under 500 km initially.
Electric vehicle fast charging technology enables rapid battery charging at power levels of 150-350 kW, reducing charging times to 15-30 minutes for 10-80% charge. Ultra-fast charging networks are expanding globally, with over 60,000 fast charging stations operational in 2023 .
