  • Are Sodium Ion Batteries Viable Alternative to Lithium?

    ALTERNATIVE POWER REPORT

    Despite lithium ion battery prices continuing to fall, interest in sodium ion (Na-ion) energy storage has not waned. Sodium ion batteries are undergoing a critical period of commercialization as industries from automotive to energy storage bet big on the technology. Sodium ion looks well placed, with superior safety, raw material costs, and environmental credentials.

    Sodium ion cells, produced at scale, could be 20% to 30% cheaper than the dominant stationary storage battery technology, lithium ferro/iron-phosphate (LFP), primarily due to abundant sodium and low extraction and purification costs. Sodium ion batteries can use aluminum for the anode current collector instead of copper, which is used in lithium ion batteries, further reducing costs and supply chain risks.

  • New Hydrogen Colors to Watch in 2024

    Hydrogen has the potential to be emissions free but only if we understand how the hydrogen is generated / manufactured or whether it occurs naturally. Several new terms have been used recently in the press, and this article explains them.

    Gold hydrogen refers to naturally occurring deposits of the gas trapped underground in a way similar to how natural gas and oil deposits are found under the Earth’s surface. This type of H2 is different from White in that White now typically refers to the gas when it is above the surface, such as in the atmosphere, but Gold refers specifically to the gas found in underground deposits.

  • Study Shows Plug-in Hybrids Aren’t as Clean as We Thought

    A new report by the European Commission shows that plug-in hybrid electric vehicles create much more emissions than we previously thought – by an average of 3.5 times as much as lab testing indicates.

    Plug-in hybrids (PHEVs) were thought to bring the best of both worlds – a large enough battery to take care of your daily tasks, paired with a gas engine for longer trips. There are downsides in cost and complexity, but the powertrain choice does provide more options than others.

  • CATL, Yutong Launch Long-life EV Battery

    CATL has launched a battery pack with Yutong Bus Co to power commercial vehicles like buses and trucks. Yutong said the new battery packs will be used in upcoming electric vehicles and that the new long-lasting EV battery has zero degradation through the first 1,000 cycles.

    The new EV battery pack, made with CATL, has a 932,000 mile (1.5 million km), 15-year warranty. Yutong calls the long-life battery an industry first. The bus manufacturer introduced another battery with a 10-year and 621,000 mile (1 million km) lifespan.
