Audi and the utility EnBW are pioneering an energy storage facility built on retired electric vehicle (EV) batteries. This partnership is being billed as the solution to a major problem in each industry.

For automobile manufacturers, the question of how to recycle retired batteries has been pressing for some time. Utilities have been struggling with the perverse problem that excess generation from renewable sources has been slowing adoption, as surges from those sources can disrupt the stability of power grids.
EV batteries have a functional life of 3-10 years after they are retired from vehicle use, making them a ready tool for use by utilities.
Portland General Electric Company (PGE) also is seeking to create a more resilient grid for the utilization of renewable energy sources. They are launching a pilot program to incentivize the installation of home battery systems to act as a virtual power plant.
In a statement released June 30, Daimler announced it will be investing “a very substantial sum” in achieving a CO2-neutral future for the transportation sector. Hydrogen fuel cell production facilities are currently in development, with an eye toward mass production of fuel cells and their component parts.

Some of the hurdles Daimler is working to overcome are the needs for highly-filtered air and stable ambient temperature and humidity. The materials and components used in fuel cell production do not allow for an easy transfer in process from conventional engine manufacturing.
The symposium of battery change mode for new energy vehicle was held June 15 in Xuzhou, Jiangsu. Data from National Big Data Alliance of New Energy Vehicles suggests that over 3 million new energy vehicles were in the system in 2019 and 900,000 vehicles are running daily. Data also suggest that new energy vehicle GVW range primarily falls under 4.5 tons.
PSR Analysis: Many numbers are in the article, some contradictory. As one of the truck OEMs, XCMG does make some excellent points on the daily use of the battery-powered vehicle, using data collected from end-users, such as working hours, range anxiety and surprisingly, maintenance and downtime.
But I want to point out one potential issue that might travel under the radar: operating cost, more specifically, fuel cost. For large fleet owners like JD.com Inc. or SF Express, fuel cost might be a key factor in choosing a battery-powered vehicle over ICE-powered vehicle for urban delivery.
There are energy companies already working with large industrial businesses to install wind or solar power onsite to address their electricity bill issue. Once completed, giant companies like JD or SF Express will significantly cut down their operating expenses on fuel, in this case, electricity.
There is one game changer out there now. How will ICE-powered light duty trucks compete with battery-powered vehicles, when the latter runs free of charge and free of emission? What will happen to all the components suppliers for light duty trucks, especially urban delivery trucks? PSR

My other article in this month’s issue of PowerTALK News describes how home battery systems, even though they are not themselves viable products for most consumers, still benefit from a virtuous cycle of product improvement and investment because of the relative success of battery-powered vehicles and other battery-powered products.

But the COVID-19 pandemic has not missed those drivers. Venture Beat magazine reports that investors are largely avoiding lithium this year, preferring to safeguard cash until the economy starts to improve. The delay in funding could have several knock-on effects.
One is consolidation in the industry. Ganfeng Lithium is picking up a lithium project from Lithium Americas, a smaller operation. Fewer, larger players in the market later on might have price consequences for lithium adoption after the economy improves and demand for those goods increases.
This article is being written the week after SpaceX successfully brought two astronauts to the International Space Station, which has been celebrated across the country as a great achievement for the United States Space program.
I certainly share the feeling that it is good to be back in space, but there is also this lingering feeling that 50 years after we landed on the moon, we might be somewhere further along than just getting back into space on American-piloted rockets.

Combining that with a pandemic that has brought us to a public health and economic situation more appropriate for the early 20th century than the early 21st century, and protests over racial inequality issues that many hoped we’d be further along with 60 years after the Civil Rights movement, it feels appropriate to reflect on the phenomenon of future-hype.
The blog article Why Have Home Battery Forecasts Been Staggeringly Wrong for Years? examines the future-hype specifically around home battery systems. Specifically, why were predictions made only four years ago, not 50 or 60 or 100 years ago, so wrong about where home battery systems would be now?
The word “hybrid” in the power generation universe has generally been understood to mean a fossil-fuel engine supplemented by another power source, usually a renewable.
Tyler Wiegert
Then, the word grew to include vehicles and equipment that ran primarily on battery power but could be switched to a smaller engine that would recharge the battery while it ran.
Now, we are entering a time when “hybrid” includes drive systems that are primarily renewable-based and supplemented by an additional renewable system.
In this sphere, alternative power has primarily meant batteries and hydrogen fuel cells; one of the major impediments to wide adoption has always been range.
R&D World magazine recently examined the global market for lithium-ion batteries and concluded that there could very well be a shortage in the next decade. They projected that recent investments will ensure supply keeps ahead of demand for at least the next two years, but that the demand for lithium in 2030 will be 2.3x higher than the global output in 2019, and investments may not be happening at the pace needed to meet it.
Tyler Wiegert
The main bottleneck is that it takes 5-10 years to bring a new lithium or cobalt mine online, but their low prices right now remove some of the incentive to make those investments.
In the absence or shortage of those investments, control of current resources will play a critical role in the production costs of lithium-powered equipment, including on-highway vehicles. In this area, as in many others, Tesla appears to be a leader. The electric car maker has made a number of moves recently to pursue vertical integration, including, most recently, signing a supply deal with Hanwha for battery production equipment. But they are also making moves to secure ownership of the raw materials needed for battery production.
Recently I was at a dinner with visiting members of my family discussing the noble transition that many manufacturers are making from producing their typical goods to producing essential goods and equipment for the coronavirus fight.
Tyler Wiegert
One that came up was Tesla’s transition to making ventilators, and one member of my family began to say that they wouldn’t want a Tesla ventilator if they were hospitalized, because it would probably catch fire and explode.
My fiance is in medicine rather than in our industry, so she took that to be a serious comment about the risk of ventilators sparking in an oxygen-rich environment. But it quickly became clear that this critic just has a deep and abiding skepticism of battery technology, because they repeatedly brought the conversation back to battery fires and cars exploding, despite there having been only 14 reported cases of Tesla vehicles catching fire between 2013 and 2019, with most of those happening after accidents.
