Two New Approaches To Wind-Powered Ships
Ships haven’t had sails for generations, but the idea is gaining new supporters as shipping companies work to lower their carbon emissions.
Globalization has spawned a tremendous increase in the number of ships crossing the world’s oceans. Ships the size of small cities haul thousands of containers and tankers as large as aircraft carriers transport millions of gallons of oil from one continent to another. Many of them run on bunker oil — a gelatinous mass of whatever is left over after the refining process is over. The stuff is so thick, it needs to be heated in order to flow and when it is burned, it leaves behind sulfurous clouds of carbon dioxide so thick they can be tracked by satellites.

The Hydrogen Stream: Hydrogen Buses Less Efficient than Battery Models
Eurac Research scientists have analyzed data from 21 fuel cell electric buses (FCEB) and battery electric buses (BEB) in Italy, comparing efficiency, consumption, temperature sensitivity, distances, and cost, and they discovered that Hydrogen buses’ tank-to-wheel (TTW) efficiency is lower than battery electric buses, indicating higher consumption variation for BEBs.

Daimler’s RIZON Electric Truck Feels like Driving a Car
Daimler recently launched a class 4-5 medium-duty electric truck brand, RIZON, and Electrek got a chance to kick the tires and drive one around. They were impressed at how well it drives (for an 18k GVWR vehicle) and how comfortable it feels like it would be on long shifts.
Rizon is a new brand from Daimler Trucks focusing entirely on zero-emissions in the class 4-5 space. Trucks of this size don’t require commercial driver’s licenses, and you’re more likely to see them around your neighborhood, doing local delivery tasks, equipment rentals, moving businesses, and the like. So, it’s nice to have clean, quiet operation instead of noisy and stinky diesel vehicles.

Why Is California Building a Refueling Network for Hydrogen Cars Nobody Uses?
Guy Youngs California is essentially the only state in the USA that has any hydrogen cars to speak of, but even in that state, there are only about 12,000 of them on the roads. Despite this, the state intends to spend hundreds of thousands of dollars per year (or more) to build a refueling network for those vehicles.
California lawmakers are now debating how much money to pour into a fueling station network for hydrogen cars.
A lobbying group for suppliers and supporters of H2 includes Shell, Chevron and Toyota is aiming for a designated 30% of the Clean Transportation Program money, which would represent about $300 million spent over the next 10 years.

Australian Mining — Can It Power All The New EVs?
Australia is already the largest exporter of lithium in the world and has the largest lithium mine in the world. Each quarter, the Australian government produces a report from the Department of Industry Science and Resources which discusses Lithium and most of the other minerals needed to support the EV revolution.
The report is 175 pages long and this article focusses on the sections dealing with copper, nickel, zinc, and lithium.

Black Mass, Black Gold, And the Truth About EV Battery Recycling
“Black mass” is a term used to refer to the residual compound formed by shredding of li-ion batteries that have reached the end of their usable life cycle. It is a huge task and challenge to recover the valuable cathode elements (lithium, nickel, manganese, and cobalt) entwined within the battery and upcycling them into usable battery materials.
RecycLiCo is among the first companies to turn that black mass into what is referred to as “black gold.” They do this by recovering almost all of the cathode…

Redesigned Zinc-Air Batteries ‘Better’ than Lithium, say Researchers
Researchers at Edith Cowan University in Australia have redesigned zinc-air batteries and have found the technology to be preferable to lithium-ion batteries – even for electric vehicles, and they claim to have overcome the technology’s notorious power output limitations.
Zinc-air batteries consist of a zinc negative electrode and an air positive electrode. The chemistry holds promise and is significantly more sustainable than lithium-based counterparts, but the poor performance of air electrodes and short lifespan has limited the technology’s power output.

Hydrogen Engines Face Production Hurdles
Liebherr’s managing director of its combustion engine business unit, Stefanie Gerhardt, has outlined four major hurdles to resolve before hydrogen can become mainstream.
Gerhardt asserted that hydrogen combustion engines can be used everywhere where electrically powered machines and hydrogen fuel cells reach their limit. And she suggested that they would be particularly useful in construction applications where economy, robustness, and high performance are required.
