A new bill introduced Friday by US Senator Angus King of Maine could unlock the true potential of electric school buses and provide stability to communities in need. The BIDIRECTIONAL Act would “create a program dedicated to deploying electric school buses with bidirectional vehicle-to-grid (V2G) flow capability.”
Zero-emission electric school buses are being deployed nationwide as state leaders and school districts look to protect the children and communities they vow to serve. New information shows school districts that replace just one diesel school bus with an electric one can reduce toxic emissions by 54,000 pounds a year.
However, the benefits of electric school buses don’t stop there. The massive batteries they utilize also make perfect energy storage devices. Several automakers and charging companies are experimenting with vehicle-to-grid (V2G) technology that enables vehicles to send energy back to the grid.
Manufacturers of electric pickup trucks (like the Ford F-150) and other EVs have dived into bi-directional charging, but this technology makes even more sense for electric school buses because they have large batteries that sit most of the day. To illustrate this point, Thomas Built Buses partnered with Proterra to show two electric school buses can send 10 MWh total back to the grid, enough to power around 600 homes.
Senator King wants to capitalize on this ability with the BIDIRECTIONAL Act to promote the widespread deployment of electric school buses with V2G capability to improve community stability.
The BIDIRECTIONAL Act is designed to accelerate adoption of EV school buses while using them for more than just a ride to school.
According to Senator King, the BIDIRECTIONAL Act will:
- Establish a Department of Energy (DOE) program to roll out electric school buses designed with V2G capabilities in communities that need them most.
- Require the DOE to report on current V2G initiatives (such as Thomas Built and Proterra) while also requiring electricity providers to consider bi-directional integration.
Senator King commented on the initiative, stating:
Vehicle-to-grid school buses are another common sense tool that can help to create a reliable grid, promote clean energy, and cut costs for local towns and school districts.
The BIDIRECTIONAL Act will assist school districts across Maine and America transition to electric buses and make sure these vehicles provide greater stability to their communities. Combined with electric bus investments in the Inflation Reduction Act, this will be an important step towards unlocking America’s clean energy future. It’s a simple, win-win bill and I hope it can get bipartisan support across Congress.
Several major electric school bus makers and other organizations are backing the bill, such as Blue Bird, Highland Electric, Lion Electric, Nuuve, Proterra, and Xcel Energy.
Electric school buses with V2G are a no-brainer. Not only will they reduce greenhouse gas emissions, protecting the communities they serve, but they can also play a key role in providing energy stability to communities in need.
The Environmental Protection Agency (EPA) just announced it would be nearly doubling EPA clean school bus program funding to $965 million in its initial round . Federal funding is a huge first step, but strong state leadership is also necessary if these clean machines are going to become widely adopted. Virginia, for example, just surpassed 500,000 electric school bus miles driven thanks to a state initiative to roll out 13,0000 electric school buses in 2019. They now have the nation’s second largest fleet of electric school buses.
I believe Senator King is wise in proposing this bill. I truly believe electric school buses have unlimited potential waiting to be unlocked, and the BIDIRECTIONAL Act can do just that.

California-based startup unveils 58 MPH electric jet ski on hydrofoils
It’s an exciting time for personal watercraft enthusiasts that want to swap a roaring engine for the instantaneous (and silent) power of electric motors. The latest electric jet ski making a splash is the Valo Hyperfoil.
Technically speaking, it’s not actually a jet ski, nor is it making that much of a splash. “Jet Ski” is a brand name owned by Kawasaki, and the Valo Hyperfoil isn’t really making a splash because it’s actually flying above the waves on hydrofoils.
But whatever you call it and whichever hydro-based pun you shoehorn into an electric watercraft article, the Valo Hyperfoil is certainly an impressive machine.
Unveiled today by California-based startup Boundary Layer Technologies, the Valo Hyperfoil is one of the most advanced personal electric watercraft we’ve ever seen.
Not only is it quite powerful, packing in a 108 hp (80 kW) motor, but it can reach a maximum speed of 50 knots (58 mph or 93 km/h).
And it will do so while flying a full 2 feet (60 cm) above the surface of the water.
As founder and CEO of Boundary Layer Technologies Ed Kearny explained in a statement provided to Electrek:
“Valo will be a complete revolution to personal watercraft. The first Jetski was on the market 50 years ago this year, and it’s time for a major upgrade. Valo will be fast, agile, and tremendously exhilarating, all while being near silent and leaving zero wake. It will be like flying a stunt plane but on water. We see this a completely new form of water based mobility”
The secret to the flying nature of the Valo is its hydrofoils, which function like a set of airplane wings under water.
They lift the watercraft out of the dense water, helping it to save energy by flying through the air. That makes the ride smoother, faster and more efficient. It also means that the Valo can get by with fewer of those heavy and expensive batteries.
The company has spent the last four years developing hydrofoil technology for commercial purposes, such as passenger ferries and container ships. Now the company is hoping to apply that technology to the recreational market with a personal electric watercraft.
As Kearny continued:
“We are passionate about bringing foiling technology and its huge benefits to ships big and small. We simply shifted from ‘big first’, to ‘fast first’. What we love about Valo is how fast we can get to market. We are bringing all the technology we were developing for massive container ships and ferries and using it to deliver one hell of a recreational product.”
Hydrofoiling boats have been made famous by the Swedish company Candela, who is already building and delivering electric speedboats with impressive hydrofoiling performance. The company is also working on passenger ferries and water taxis for commercial use, but hasn’t shown off a personal electric watercraft like the Valo.
Other companies like Taiga have leveraged their electric snowmobile technology to demonstrate personal electric watercraft. But their planing hulls will have a hard time matching the efficiency of hydrofoils like those displayed on the Valo.
Boundary Layer Technologies expects to have a small number of limited edition Founders Edition Valos by the summer of 2023 Full production vehicles aren’t expected to hit the water before 2024. The anticipated price for the production vehicles is $59,000, though we don’t yet know what price tag those first run Founders Edition vehicles will carry.
Until then, we can at least look at these pretty renders.

Hitachi Energy debuts wireless grid tech that prevents wildfires
Hitachi Energy just launched wireless Spark Prevention Unit indicators that help prevent wildfires by enabling remote monitoring.
According to the US Department of Energy, approximately 10% of wildfire ignitions are sparked by faults on electrical infrastructure or electric equipment failure. Hitachi Energy’s new Wireless SPU Indicators allow utilities to monitor the grid remotely, in real time, with automated visual inspection rounds.
The SPU monitors the current and thermal load of surge arresters – which protect equipment from surges in the power system – installed in wildfire risk areas.
If there’s a thermal overload in the grid, the SPU interrupts the current flow and disconnects the surge arrester, thus preventing any arcing – which is when a circuit becomes overloaded and overheats – sparking, or ejection of hot particles that could potentially start a wildfire.
A visual indicator on the SPU lets the utility field crew know that it needs to be replaced. Hundreds of thousands of SPUs installed in some of the world’s most wildfire-prone areas, such as in the United States and Australia, have had a real impact in preventing wildfires. Being able to monitor them remotely is only going to improve wildfire prevention.
