An article in the latest issue of IEA Energy: The Journal of the International Energy Agency reports that Estonia, which has the most developed oil shale industry in the world, is collaborating in pursuing wider use of oil shale in a cleaner, more sustainable manner. Different that shale oil—i.e.,
But for something like building or grid-level powerstorage—where they’re just going to sit there—the fact that you get more kilowatt hours per dollar becomes a strong selling point. —UMD Professor Chunsheng Wang. Sodium-ion batteries are also heavier, so for now they’re not suitable for most vehicles and airplanes.
An Israeli startup thinks they may have found the solution to rural electric vehicle charging and powerstorage. One of the most significant challenges facing electric vehicle charging in rural areas worldwide is inconsistent power generation; if power isn’t generated, you can’t charge your car.
And because such batteries could be installed and operated just like conventional solid lithium-ion batteries, without any of the auxiliary components needed for a lithium-air battery, they could be easily adapted to existing installations or conventional battery pack designs for cars, electronics, or grid-scale powerstorage.
The company also plans to invest in continued advancements in photovoltaic cells and in powerstorage—and smaller, more energy-efficient sensors. This article appears in the August 2022 print issue as “Julie Angus.”. I can also imagine having aerial drones or underwater vehicles as part of our data-collection services.
cell as % of cost = 50% (BCG article w. EnerDel expects the pack to depreciate more slowly than the rest of the vehicle and to have a secondary life in fork lift trucks or residential powerstorage once the car has been recycled. Sub-pack share of system cost = 90%; 0.9* 2,400 = $2160 (pack, wiring, testing = $1500 - $2k).
The descriptive article GM and PG&E to test how EVs can power homes during blackouts provides several jumping-off points for your independent investigation. In fact, there have been predictions of late that vehicle-to-grid bi-directional charging capability will one day be a requirement for all vehicle sales.
Sven Thesen, the communication and technology director for Better Place , a start-up that is gaining traction (see this recent New York Times article ) in its effort to create a network for electric cars in various countries, likened the concept of electric cars to cellphones. Fifteen years ago, how many people had a cellphone?”
And, you have to recognize that they pull a hell of a lot of power through the local grid: there will come a time when we will see utility transformers popping from all the current being drawn (imagine just a few dozen EVs fast-charging simultaneously, on 480V at 500A: wow). I would prefer to recharge at home, and could do so.
