Maritime batteries do not have to electrify every ship to reshape fuel demand; short-sea, port-adjacent and hybrid-electric operations are already a serious wedge.
A useful paper has landed in the Nature family on the techno-economics of electrifying short-sea shipping, and the result should make the maritime fuel debate a little less vague. The paper does not claim that every ship becomes battery-electric. It does not need to. It finds that by 2030 a … [continued]
Engine-supported air lubrication may trim ship fuel use by reducing hull friction, but the useful number is net savings after the air has been compressed and delivered.
The interesting part of Everllence and Silverstream’s Engine Supported Air Lubrication concept is not that ships can reduce drag by pushing air under the hull. That has been known for decades, and commercial systems are already in service. The interesting part is where the air comes from, because air lubrication’s … [continued]
Hydrogen buses may look operationally familiar, but the procurement risk sits in the fuel supply, depot infrastructure, maintenance depth, uptime, and long-term cost.
Hydrogen buses are real. They can carry passengers, complete routes, refuel, and operate in public transit fleets. That much has been demonstrated often enough that it is no longer the useful question. The useful question for transit agencies is whether hydrogen is a better procurement choice than battery-electric buses once … [continued]
Belgium’s hydrogen refuelling announcements need to be tested against vehicles served and kilograms dispensed, not just station capacity.
Belgium has another hydrogen refuelling announcement, and on the surface it sounds like progress. Atawey is selling three new hydrogen stations to Colruyt Group and Virya Energy for heavy-duty mobility, with a stated combined distribution capacity of more than 7 tonnes per day and deployment planned by the end of … [continued]
Climate-tech claims need to be tested against comparators, customers, costs, and repeat procurement, not just announcements and pilots.
Energy transition analysis is littered with evidence that is real and stories that are not. A pilot exists, therefore the market is forming. A government grant lands, therefore the technology has been validated. An offtake agreement appears, therefore customers must be willing to pay. A large company issues a press … [continued]
The demand for SUV vehicles has never been higher but contributes to higher prices that drive some out of the market.
Green H2 or not, hydrogen trains will help the Czech Republic cut ties with Russian gas suppliers.
Originally published by Union of Concerned Scientists, The Equation. By Dave Cooke EPA just put out its annual report on the emissions and fuel use from passenger cars and trucks. The good news: vehicles are more efficient than ever before, with the average vehicle achieving 25.4 miles per gallon on-road and every … [continued]
President Joe Biden’s decision to nominate Pete Buttigieg to lead the Department of Transportation may be among the most consequential of his presidency.
CNN reported that Tesla’s stock surge isn’t just making Elon Musk and Tesla investors rich — it’s affecting other industries as well. Investors who are focusing on other industries, such as lithium and batteries, are also benefitting from Tesla’s success
