A super El Niño isn't about the planet heating up, but about weather patterns shifting dramatically. Rain, storms, and heat move to unprepared areas, disrupting established climates. #ElNino #ClimateChange

Don't pit battery tech against each other! Sodium won't replace lithium for phones or EVs due to energy density. It's targeting grid storage and home batteries, complementing lithium's reign. #BatteryTech #EnergyStorage

As the grid gets cleaner, the midday energy glut and evening shortage will worsen. The only fix? Staggering amounts of storage to hold cheap midday power for when it's truly needed. #EnergyStorage #CleanEnergy

The world's largest battery company is investing billions in a 30-year-old chemistry. Why? It’s not about batteries, but about a fundamental supply chain idea. #Energy #Innovation #SupplyChain

The world's biggest battery company is betting on old chemistry: Sodium-ion. It's not much cheaper than LFP now, but its raw materials are far more abundant, promising stability for long-term energy planning. . #BatteryTech #Sustainability

Lithium batteries pose a fire risk due to flammable electrolytes, as seen with the Galaxy Note 7. Cold temps worsen this by causing dendrites that can short the cell, and reduce EV range by up to 40%. #BatteryTech #EV

We can make jet fuel without oil, but economics is the real hurdle. Current synthetic fuel costs are massive, and scaling up is a huge challenge. The gap between synthetic and traditional fuel prices is just too wide for widespread adoption. #SustainableAviation #FutureOfFlight

Synthetic fuels don't make sense for passenger cars with EVs on the rise. But for long-haul flights, like NY to London, they're hard to replace. What do you think about sustainable aviation fuel? #SustainableAviation #FutureOfFlight

Invented in 1925, Fischer-Tropsch synthesis creates jet fuel chemically identical to fossil fuels. It's a drop-in replacement, even burning cleaner due to the absence of sulfur and aromatics. . #FischerTropsch #SustainableFuel

Stop waiting for perfect solutions. Focus on the hardest part first, and let the rest be plug-in. Like this company in Germany turning CO2 into fuel, running 24/7. #ClimateTech #Innovation

Aviation's climate impact is 2-4x worse than CO2 alone due to contrails. These form from soot particles in exhaust. Synthetic e-fuels burn cleaner, producing fewer particles and significantly reducing contrails. #Aviation #ClimateChange #SustainableFuels

Lithium isn't the rarest battery ingredient. The real challenge lies in the positive electrode, particularly nickel, manganese, and cobalt. Cobalt is the core issue, with 76% mined in the Democratic Republic of Congo, often under questionable conditions. #BatteryTech #SupplyChain

Sodium was the frontrunner for rechargeable batteries in the 1960s, but its molten state at high temperatures made it impractical. Lithium won out due to its ability to work at room temperature, and its ions fitting perfectly into graphite structures. #BatteryTech #ScienceFacts

CATL's sodium battery uses abundant materials: sodium (1000x more common than lithium), iron, and manganese. The negative electrode is hard carbon, avoiding graphite. . #BatteryTech #Sustainability #Innovation

CATL is investing billions in sodium-ion batteries like Naxtra, offering impressive specs for cars and grid systems. The real question: why now for a technology that could have existed decades ago? #BatteryTech #Innovation #ElectricVehicles

The undisputed king of lithium-ion batteries just unveiled a grid-scale storage system with ZERO lithium. Why is CATL, the industry leader, betting against its own technology, and what's inside this cheaper, potentially game-changing cell? #BatteryTech #EnergyStorage #CATL

The Titan submersible's hull degraded with every dive, yet its use continued despite damage. The push for more dives persisted, even as evidence mounted. #TitanSub #SafetyFailure
