Ports need more investment for bigger ships, resilience and decarbonization just as some of the bulk cargoes that funded them begin to decline.
Ports are being asked to make infrastructure decisions that will last thirty, forty or fifty years while several of the assumptions that paid for their existing infrastructure are changing at the same time. Ships are getting larger, requiring deeper channels, larger cranes and more capable tug fleets. Climate disruption is … [continued]
OceanX survived severe Yagi wind and waves with little reported nacelle inclination, but its stayed, weather-vaning architecture is the more interesting result.
OceanX gave me two immediate reasons to be skeptical. It puts two turbines on one floating platform, and it puts the rotors downwind of their supports rather than in front of them. I had looked at both ideas years ago and found good reasons why the wind industry had largely … [continued]
Green Lightning produces measurable nitrate, but its claimed fertilizer replacement is vastly larger than the nitrogen it actually fixes.
Green Lightning really does make nitrogen fertilizer from air and electricity, but it makes very little of it compared with what its marketing says it can replace. Nitrogen is not merely something that encourages a plant to grow. Nitrogen atoms become part of the plant itself, incorporated into proteins, chlorophyll, … [continued]
The Netherlands cut its 2040 hydrogen forecast by more than half as electrification displaced hydrogen across power, heat, buildings and transport—but the remaining forecast still assumes substantial demand growth.
Three years is a long time in hydrogen strategy. The Netherlands’ 2023 National Energy System Plan projected roughly 460 petajoules of gaseous hydrogen demand in 2040. Its 2026 National Energy System Plan update cuts that central estimate to about 200 PJ, a reduction of roughly 57%. This is especially interesting … [continued]
The leaked preferred option would eliminate binding national RFNBO consumption targets while retaining an indicative EU hydrogen target, financing and enabling measures.
Europe’s current Renewable Energy Directive requires renewable fuels of non-biological origin, or RFNBOs, to account for at least 42% of relevant industrial hydrogen use by 2030 and 60% by 2035, subject to exclusions and flexibilities. Those provisions do more than subsidize hydrogen production. They create a specified market for a … [continued]
Tugboats combine brief demands for very high thrust with repeated operation inside the same ports, making their duty cycle unusually well suited to electrification.
Tugboats do not initially look like good candidates for battery propulsion. A harbour tug has to shove, pull and control ships weighing tens or hundreds of thousands of tonnes, sometimes in wind, current and confined channels where losing thrust is not an acceptable outcome. Modern ship-assist tugs consequently carry propulsion … [continued]
DNV says shore power, plug-in hybrids and fully electric ships could materially reduce future shipping fuel demand, but those pathways sit outside the simulation producing its headline 2050 fuel requirement.
DNV’s new Maritime Forecast to 2050 puts a very large number on shipping’s future demand for low-carbon molecules. In its strongest global-regulation scenario, internationally operating ships above 400 gross tonnes require about 185 million tonnes of oil equivalent of low-GHG fuel in 2050, roughly 7.7 to 7.8 exajoules. That implies … [continued]
More than 300,000 plant-protection drones now perform roughly 203 million hectare-treatments annually in China. The market has moved beyond adoption into service, maintenance, renewal and operating standards.
Agricultural spray drones are no longer an emerging technology in China. They are ordinary farm machinery at extraordinary scale. China entered 2026 with about 309,000 plant-protection drones, and those aircraft performed roughly 203 million hectare-treatments during 2025. A hectare treated three times counts as three hectare-treatments, so that figure measures … [continued]
China’s high-speed rail removes dense short-haul corridors from aviation while helping define the regional routes where electric aircraft can make more sense.
The electric-aviation contest is often presented as a race between aircraft startups. That is probably the wrong unit of analysis. An airplane that flies once, wins a certification milestone or accumulates a large order book has demonstrated something useful, but it has not demonstrated an industry. What matters is whether … [continued]
Cheap working fluids do not make cheap electricity storage. Compression, thermal management, containment and expansion turn apparently simple gas storage into process infrastructure.
Two years ago I called compressed-gas electricity-storage claims mostly hot air. Since then the sector has produced exactly the sort of evidence that should force a reassessment rather than a repetition of the old argument. China has commissioned the 600 MW / 2.4 GWh Huai’an compressed-air demonstration, Hydrostor has pushed … [continued]
