Researchers at McGill University in Canada have increased a battery’s energy density by adding a rare-earth metal to an anode.
The scientists added a small amount of neodymium (Nd) to the anode in a bid to increase its energy density without compromising safety. This resulted in a 19% increase in energy density.
Over a year ago, Ethiopia became effectively the first country in the world to ban the import of internal combustion engine vehicles. This was an immediate ban on the import of all ICE cars. The motivation wasn’t environmental, but economic: A high fossil fuel import bill of over US$5 billion a year, was taking a huge chunk of the country’s scarce foreign currency resources. Energy security and self-sufficiency were other major drivers.
Ethiopia’s ban covered fully built units and left out semi-knocked down (SKD) and completely knocked down (CKD) ICE vehicle kits. That meant companies importing SKD and CKD kits for local assembly could still do so.
In September 2024 the Maersk McKinney Møller Center produced a pre-feasibility study on battery-powered vessels. The report identified battery-hybrid propulsion as an essential part of shipping’s decarbonization toolkit. It demonstrates a clear understanding that batteries offer significant efficiency gains over internal combustion and that partial electrification can sharply reduce greenhouse gas emissions and local air pollution.

The rising demand for zero-emission mobility goes beyond the nice idea of preventing a catastrophic climate crisis. EVs are a better fit for the connected, electrified lifestyle of the 21st century; they offer more opportunities for convenience, they are more useful for weathering power outages and climate-connected emergencies, and they are more adaptable to the needs of fleet managers, among other advantages.
However, while some researchers note that “salt batteries” are not quite ready for prime time, other stakeholders — including industry leader CATL — are already laying plans for mass production. Last month, CATL also burned up the Internet when it announced a suite of two sodium-ion batteries ready for full volume production by the end of this year.
The world’s sources of critical minerals are increasingly concentrated in just a few countries, most notably China, leaving the global economy vulnerable to supply cutoffs that could disrupt economies and hit consumers with higher prices, a report from International Energy Agency (IEA) has stated.
The report looked at the availability of minerals and metals that may be small in quantity but large in impact when it comes to shifting the economy away from fossil fuels toward electricity and renewable energy.
The U.S. had a robust policy in place to promote the adoption of electric cars, and it used all the tools conservatives say they like — carrots such as financial incentives instead of sticks such as mandates. But now, according to the IEA (International Energy Agency), USA is moving backwards while the rest of the world continues to move forward.
In its EV Global Outlook 2025 report, the IEA says that 20% of new cars sold worldwide in 2024 were electric, a definition that includes plug-in hybrids as well as battery-electric cars.
A decade ago, many people believed hydrogen fuel cells were the future, not battery-electric cars. The debates raged and it was common to have press releases, auto executive statements, and debates about the future of hydrogen-powered cars.
In the last decade or so, the market apparently has decided that hydrogen-powered cars do not make sense, and they can’t compete in the market as a result. Despite this situation, there are still plenty of discussions, trials, and vehicle development programs for hydrogen-powered trucks.

In theory, hydrogen can compete in the truck market, but in practice, it’s an entirely different matter. Battery technology keeps improving rapidly, and solutions for battery-electric trucks are becoming clear. If battery costs keep coming down — as expected — and proper charging hubs for heavy-duty electric vehicles get developed, battery-electric trucks seem set to win the day.
