Why the National Renewable Energy Laboratory just banned electric bikes
The National Renewable Energy Laboratory (NREL) has recently announced a hardline approach that bans the entrance of electric bicycles by visitors or staff due to safety concerns.
The NREL is a federally-funded R&D center that focuses on sustainable energy solutions, including research into solar energy and energy efficiency, among others.
According to the NREL’s fire marshal Nicholas Bartlett, micromobility devices such as electric scooters and bikes are no longer permitted to be charged or stored in the buildings.
As Bartlett explained:
“The data in the past few years shows an alarming trend of injuries and deaths, as demonstrated by entities such as NYFD and the UL Fire Safety Research Institute. The fires and explosions are attributed to a wide variety of causes such as mismatched chargers, overcharging, uncertified/Listed batteries, poor manufacturing quality, home made devices, etc. We cannot necessarily control what people purchase and use, but in some instances we are able to put restrictions on where and how an activity can be done (and we routinely do for everything from experiments with chemicals to fall protection).”
While still rare, some college campuses and government housing initiatives in the US have announced similar bans under the guise of fire safety.
For its part, the NREL has shown tacit support for electric bikes and micromobility in the past, and isn’t saying that employees should avoid riding e-bikes to work. As an alternative to storing or charging e-bikes indoors, such as in employees’ offices, Bartlett shared that the NREL has “worked to implement outdoor charging locations, at a reasonable distance from building entrances, such as the one shown here,” alongside a photo of a short bike rack with three parking slots next to an outdoor electrical outlet.
The NREL has an annual budget of US $783.5 million and a staff of over 2,600 people.
Electrek’s Take
Frankly, I’m quite disappointed in the NREL for getting caught up in this sensationalism. This is the e-bike equivalent of your ignorant neighbor quipping “I see you bought an electric car… better not park it in the garage unless you have fire insurance”.
The fact of the matter is that e-bike fires, while a legitimate threat, are also a tiny, minuscule threat. They get a disproportional amount of media attention because those headlines get far more clicks (and thus make more money) than “Millions of e-bikes charged uneventfully today, just like yesterday.”
I understand that the NREL’s goal here is to protect their staff. But if that’s truly the case, then they would be much better served with a scientific approach to the problem. This knee-jerk reaction likely “feels right” to the decision makers because they saw several scary headlines and now felt like they are doing something, but the data doesn’t support the move. Even a more soft-touch approach, such as banning charging indoors while still letting employees park their e-bikes in their offices, would have been a major improvement. E-bike fires in buildings are exceedingly rare. Of the small number that do occur, cases where the e-bikes spontaneously combusted while in storage are a small subset of an already small subset. The small number of e-bike fires has almost always occurred during charging (generally due to charging mistakes and/or ultra-low quality batteries).
Instead of banning e-bikes in the building, the NREL could have a much larger impact on their staff’s health and safety by banning arriving at work by private automobile. Essentially every study on the subject has proven that private cars are several times more deadly than public transportation. But hey, why let data ruin good intentions?
That isn’t to say that more effort shouldn’t be put into higher quality e-bike manufacturing principles as well as regulating out the more dangerous dirt-cheap e-bikes. But let’s get real. E-bikes sitting in the corner of someone’s office are saving countless more lives than they are risking.

Oil prices jumped on Friday as the U.S. Treasury Department announced sweeping sanctions against Russia’s oil industry.
Brent gained $1.92, or 2.5%, to $78.84 per barrel by 11:12 a.m. ET, while U.S. crude oil advanced $1.89, or 2.56%, to $75.81 per barrel. Brent broke $80 per barrel for the first time since October earlier in day, hitting a session high of $80.75.
The sanctions target Russian oil companies Gazprom Neft and Surgutneftegas and their subsidiaries, more than 180 tankers, and more than a dozen Russian energy officials and executives. The sanctioned executives include Gazprom Neft CEO Aleksandr Valeryevich Dyukov.
The sanctioned vessels are mostly oil tankers that are part of Russia’s “shadow fleet” that has dodged existing sanctions on the country’s energy exports, according to the Treasury Department.
“The United States is taking sweeping action against Russia’s key source of revenue for funding its brutal and illegal war against Ukraine,” Treasury Secretary Janet Yellen said in a statement.

“With today’s actions, we are ratcheting up the sanctions risk associated with Russia’s oil trade, including shipping and financial facilitation in support of Russia’s oil exports,” Yellen said.
The perception in the oil market is Indian and Chinese refiners that have imported Russian oil will have to scramble for barrels from the Middle East, said Bob Yawger, executive director of energy futures at Mizuho Securities, in a note to clients Friday.
The Biden administration has sought to ratchet up pressure on Russia and dispense aid to Ukraine before President-elect Donald Trump takes office.
“The Biden administration opted for more robust energy sanctions, which caught the oil market especially complacent about sanctions risks,” said Bob McNally, president of Rapidan Energy Group.
“Therefore, we expect today’s material risk premium in Brent to stick pending signals from the Trump team as to whether they will continue these sanctions,” McNally said.
Hydrostor’s GEM A-CAES has received a conditional loan guarantee of up to $1.76 billion from the US Department of Energy (DOE) to build the Willow Rock Energy Storage Center, a cutting-edge compressed air energy storage (CAES) system, in Eastern Kern County, California.
If everything goes as planned, Willow Rock will bring 500 megawatts (MW) and 4,000 megawatt-hours (MWh) of long-duration energy storage (LDES) to the southern California power grid.
This system will lower energy costs, improve grid reliability during peak demand, and expand the rollout of renewable energy into the grid. Here’s how it works and why it’s unique.
How compressed air energy storage works
CAES technology is all about storing energy for later use, especially when the sun isn’t shining or the wind isn’t blowing. Here’s how it works:
- Storing energy: The system takes surplus energy (often from renewable sources like solar or wind) and uses it to compress air, which is stored in underground caverns.
- Releasing energy: When the grid needs power, the compressed air is released, passing through a turbine to generate electricity. Willow Rock will be able to dispatch stored energy at full power for over eight-hour periods.
Unlike conventional batteries, CAES can scale up based on the size of the storage cavern and doesn’t rely on scarce critical materials. It’s durable, too –systems like Willow Rock are designed to last over 50 years.
Why advanced CAES is different
Traditional CAES systems face two big challenges: wasted heat and inconsistent power output. Willow Rock’s advanced compressed air energy storage system (A-CAES) technology solves these problems:
- Thermal energy capture: Conventional CAES loses around 50% of energy during the air compression process. Willow Rock pairs a proprietary thermal storage system with this process, so it captures, stores, and reuses heat from the compression cycle.
- Constant Pressure: Traditional systems lose efficiency as underground air pressure drops. Willow Rock maintains consistent pressure by using water from an above-ground reservoir. As a bonus, the facility will be a net producer of fresh water, as water condensed during the compression process will be captured and reused.
This innovative design means A-CAES systems can be installed in a greater variety of underground conditions – an estimated 80% of US geology could support similar systems, opening the door for wide deployment.
Willow Rock will create up to 700 construction jobs at its peak, and 40 full-time operations roles will follow. These positions require skills similar to those used in the oil and gas industry, making it a natural fit for Kern County, a region with roots in fossil fuel production.
GEM A-CAES is a subsidiary of Hydrostor USA Holdings, a subsidiary of Hydrostor of Canada.

Chinese EV automaker Build Your Dreams (BYD) has unveiled its ATTO 2 compact SUV to the European public. The launch, which took place at the Brussels Motor Show, kicks off BYD’s next EV entry into European and UK markets. The BYD ATTO 2 is smaller and more affordable than its SUV siblings, with a decent range to boot, perfect for European roads.
The ATTO 2 is a rebranded version of the Chinese EV automaker BYD’s Yuan Up – an ultra-affordable compact SUV that debuted in China in February 2024. BYD may not be bringing “Yuan” branded EVs over to new markets in Europe, but that lineup continues to grow each month.
BYD currently sells four all-electric models in the UK and seven in Europe, including the ATTO 3 SUV. Today, BYD debuted a rebranded version of the Yuan Up called the ATTO 2, which will go on sale to customers in the UK and Europe next month.
BYD unveils ATTO 2 in Brussels, sales begin in February
The Brussels Motor Show recently kicked off as the first major automotive expo in Europe in 2025, and BYD showed up with a new affordable BEV option to complement the ATTO 3. Per BYD executive vice president Stella Li:
We’re excited to start 2025 with another important model for our plans in Europe. The B-segment SUV class is incredibly popular here, and with the ATTO 2, we have an agile and versatile offering that will appeal to that large potential customer base. It takes all of BYD’s strengths in batteries, electric motors and Cell-to-Body construction and combines them in a compact package that brings new intelligent technologies to the urban SUV class.
The ATTO 2 is 4,310mm long, 1,830mm wide, and 1,675mm tall—145mm shorter and 45mm slimmer than its ATTO 3 sibling. Despite its compact size, the ATTO 2 offers up to 1,430 liters of cargo capacity with its rear seat down.
The ATTO 2 also sits atop BYD’s e-Platform 3.0, the first of the brand’s compact SUVs to utilize Cell-to-Body (CTB) construction, which integrates the battery completely into the vehicle chassis—this design results in optimized space and overall increased vehicle rigidity.
Speaking of batteries, the EU and UK customers who opt for an ATTO 2 can experience BYD’s proprietary Blade Batteries, which integrates LFP cells directly instead of fitting them into multiple modules. BYD says customers can choose between two battery sizes in their ATTO 2 order. At launch, a standard range edition will utilize a 45.1 kWh Blade Battery, delivering a (WLTP) 312 km (194 miles) range.
However, BYD said a larger-battery version of the ATTO 2 will arrive in the coming months and offer drivers greater range. The automaker is not yet sharing individual pricing for the ATTO 2 in the UK or Europe. Still, a representative for the company said the compact SUV is expected to land between the BYD Dolphin and ATTO 3 BEVs, which in the UK cost 26,140 GBP ($32,157) and 37,140 GBP ($45,689) respectively.
ATTO 2 sales are expected to begin in February.
