Bill Gates' hydrogen-powered superyacht Breakthrough offers silent, zero-emission cruising - but at a steep cost. With limited refueling infrastructure and green hydrogen priced at $36/kg, clean sailing runs $59 per nautical mile. HVO diesel remains the practical fallback. While Breakthrough showcases innovation, EVWorld.com asks the hard questions: Is hydrogen truly viable for marine travel, or just a billionaire's experiment?
CATL's new Naxtra sodium-ion "salt" EV battery costs just $10–$19/kWh - about one-tenth of current lithium-ion prices (~$100–$115/kWh). It retains 85% capacity after 3.6M miles, charges at up to 5C (full in ~12 min), and goes 30–80% in 30 min even at –30 °C with ~93% usable capacity. The low cost, long life, and cold-weather performance could transform EV affordability and durability.
British-market buyers can now opt to pay a monthly fee for that horsepower increase..details in fine print, where a disclaimer notes that "Engine power is [148 hp] as standard, [168 hp] if you activate the optional power upgrade for a fee."
"...the fee is equivalent to $22.50 per month, $225 for a year, or a one-time purchase of $878...the one-time purchase is priced the same as 39 months of monthly subscription..."
Compelled by federal court ruling, the Trump administration unfroze $5B for EV fast chargers, dropping equity and climate rules. Funds target interstates via the NEVI program, with 80% federal coverage and 20% local match. Gas stations gain easier access, but rural and underserved areas lose priority. Critics warn of charging deserts and slower adoption. States must submit revised plans in 30 days to access funding.
Hydrogen's Flight Path: Fuel Cells, Turbines, and the Economics of Clean Aviation
10 Oct 2025 | Aviation is shifting from Jet A to four fuel systems: electricity, hydrogen (fuel cell and combustion), SAF, and petroleum. Fuel cells suit short-haul aircraft; hydrogen combustion may power long-range jets. SAF bridges legacy fleets. Hydrogen costs - $5-$7/kg today, possibly $2/kg by 2040 - impact ticket prices and infrastructure decisions. Airport authorities, airlines, and governments will share deployment costs. Each fuel has distinct environmental pros and cons shaping aviation's net-zero future.
