Electric buses are an upgrade over their gas-powered counterparts in every single way. New technology and software solutions are unlocking the potential behind these zero-emission heavy-duty EVs.The mighty machines are now being used to build a vehicle-to-building (V2B) “resilience hub” with emergency backup capabilities.

The project is being funded by the California Energy Commission (CEC) and is designed to show the value of bidirectional charging and V2B capabilities in electric buses.

You may have heard of vehicle-to-grid (V2G), which uses two-way flow to send energy from an electric vehicle or bus back to the grid. Several companies are solely focused on advancing bidirectional EV charging solutions to reduce emissions further and provide backup energy options.

The Intelligent Transportation Systems program (part of the Department of Transportation) estimates electric buses with V2G technology can eliminate 1,000 metric tons of C02 emissions on average over their lifetime, while electric school buses can erase over 1,400 metric tons.

The new CEC-sponsored program focuses on a similar solution, using electric buses with V2B to provide backup energy, creating a “resilience hub” for clean energy generation during emergencies.

Details behind the “V2B Oakland” program using electric buses

The “V2G Oakland” project, what it’s being called locally, will use the energy from zero-emission electric buses (owned by AC Transit) to supply clean power and filtered air-conditioning to Oakland residents.

The electric buses using V2B will be used at the West Oakland Branch of the Oakland Public Library during poor air quality from heat or smoke.

Several partners are working to bring the project to life, including the Center for Transportation and the Environment (CTE), The Mobility House, AC Transit, New Flyer, Schneider Electric, and the City of Oakland.

Each battery electric bus will generate six hours of backup energy for the library, reducing emissions that would otherwise be released with diesel generators. The US managing director at The Mobility House states:

We are thrilled to bring our “vehicle-to-everything” expertise from numerous projects in Europe and Asia to now develop the first-ever vehicle-to-building resilience hub in the US.

Jana Gerber, president of Microgrids at Schneider Electric, adds:

Powering emergency shelters with islanded energy supply is an innovative feat we are honored to help facilitate. It is also exciting to demonstrate how different technologies can integrate with each other so seamlessly and intelligently to allow for crucial backup power for the community and infrastructure.

The CEC contributed $3.2 million toward the project through its electric program investment charge strategy, with another $400,000 made possible through AC Transit and West Oakland Environmental Indicators Project (WOEIP).

Battery electric buses loaded with V2B can provide a quicker response in the event of an emergency while avoiding harmful emissions that would otherwise be released through a backup generator.

The infrastructure behind the project expects to be completed by mid-2023, and testing will take place through July 2025.

World's largest EV maker unveils new sodium battery electric motorbikes

Yadea, which has claimed the title of the world’s largest electric vehicle maker for seven years running, has just announced a new electric motorbike powered by the company’s innovative HuaYu sodium-ion battery technology.

Yadea has long dominated the electric two-wheeler and three-wheeler market globally, but has generally relied on both lithium-ion and lead acid batteries to power its vehicles in different markets.

The newly unveiled electric scooter uses Yadea’s recently introduced sodium battery technology, offering what the company says is outstanding performance in range, charging speed, and safety. Using the HuaYu Sodium Superfast Charging Ecosystem presented by Yadea, the battery can reach 80% charge in just 15 minutes, providing greater convenience for riders.

Yadea’s sodium battery has successfully passed more than 20 safety tests, many focusing on its resistance to fire and explosions under extreme conditions like punctures and compression.

Yadea’s new sodium battery offers an energy density of 145 Wh/kg and a lifespan of up to 1,500 cycles at room temperature, with the company rating it for a five-year useful lifespan. It also includes a three-year warranty for added assurance.

With excellent low-temperature capabilities, the battery retains over 92% of its discharge capacity at -20°C, making it well-suited for colder climates.

Sodium batteries present major advantages

Most electric vehicles used in the West, especially electric two-wheelers, rely on lithium-ion batteries for their high energy density. But sodium-ion batteries offer many benefits over traditional lithium-ion batteries.

Sodium is an abundant element on the planet and is easily accessible, unlike lithium, which is concentrated in specific regions and often expensive to extract. This abundance can make sodium-ion batteries cheaper to produce, reducing costs for EV manufacturers and potentially making electric vehicles more affordable.

Lithium mining also has environmental challenges, such as water depletion and habitat destruction. Sodium, on the other hand, can be sourced from seawater or common salts, offering a more sustainable and environmentally friendly option.

Sodium-ion batteries are less prone to overheating and thermal runaway compared to lithium-ion batteries. This makes them inherently safer for electric vehicles, reducing the risk of fires and improving consumer confidence in EV technology.

Sodium-ion batteries perform better than lithium-ion in cold climates. Lithium-ion batteries struggle with capacity retention in freezing conditions, but sodium batteries maintain efficiency, making them ideal for EVs in colder regions.

Sodium batteries still have challenges to overcome

While sodium-ion batteries are promising, they currently have a lower energy density than lithium-ion batteries, meaning they store less energy per unit of weight.

For EVs, this translates to shorter driving ranges for the same-sized battery. That’s especially important in electric two-wheelers like motorbikes and electric bicycles, which don’t have much extra space for storing bulky batteries.

However, advancements in cathode materials and battery architecture are quickly closing this gap, which Yadea has demonstrated. These sodium-ion batteries still can’t match the energy density of lithium-ion batteries, but as they continue to improve their energy density, the technology’s other major advantages provide encouraging signs for larger adoption in the industry.

Yadea’s status as a major electric motorbike maker also means that its adoption of sodium-ion battery technology could help lead the entire industry towards this battery chemistry, bringing safety and performance benefits along with it.

Last year I had the unique opportunity to visit one of Yadea’s global manufacturing sites.

CES2025 | John Deere autonomous mower promises a perfect cut, every time

At CES2025, the impressively built-out John Deere exhibit was all about automation. Autonomous job sites, autonomous farms … but it was this new, battery electric, autonomous lawn mowing robot that stole the show.

The self-driving Deere mower robot was positively dwarfed by the giant farm machinery surrounding it, but it continues to prove that humans will pack bond with anything as more than one burly-looking and grizzled man asked what its name was. (It’s Howard. I’ll fight you.)

For his part, Howard packs a 21.4 kWh battery pack that runs a suite of electric motors that includes a drive motor and three cutting blade motors spread across a 60 inch cutting deck – but it’s not the electric motors that make John Deere’s little robot mower cool, it’s the way it works.

See, instead of using “just” GPS data or “just” repeating a pre-recorded run, Howard can do something in between. The way it was explained to me, you would ride the stand-up mower around the perimeter of the area you wanted to mow, select a pattern, then hop off, fold up the platform, and let it loose. Howard mows just the way you would, leaving you to focus on edging, planting, or (let’s face it) schmoozing with the clients.

It’s exactly the sort of help landscapers are looking for.

But that should come as no surprise, of course. John Deere, perhaps more than most companies, knows its customer. “We’ve been in the turf business for 60 years — it’s a core part of Deere,” says Jahmy Hindman, chief technology officer at John Deere, explaining things beautifully. “The work that’s being done in this industry is incredibly labor intensive … they’re not just doing the mowing work. They’re doing the tree trimming, maintaining flowerbeds and all these other jobs. The mowing is table stakes, though, for them to get the business. It’s the thing they have to do in order to get the higher value work.”

Tim Lewis, lead engineer with the commercial automatous mower, told Lawn & Landscape that the industry in general has a high turnover rate as well, making it difficult to hang to people who know where one job ends and another begins. “There’s a lot of nuances it takes to do these jobs effectively,” he explains, “so “Autonomy can help with that.”

The John Deere autonomous commercial mower (there’s no snazzy alphanumeric, yet) leverages the same camera technology as other Deere autonomous machines, but on a smaller scale (since the machine has a smaller footprint). With two cameras each on the front, left, right, and rear sides of the little guy, he has a 360-degree view of the world and enough AI to lay down a pattern, avoid an obstacle, and shut off if it thinks it’s about to mow down something (read: someone) it shouldn’t.

John Deere will have Howard on display through tomorrow at CES in the LVCC’s West Hall. If you’re in town, be sure to go say hi.
