Every summer, millions of people across the country stay indoors to keep cool and stay healthy. In a summer like 2021’s record-setting heat wave, there’s nothing more satisfying than the feeling of a crisp, air-conditioned room. 

But heat is not just inconvenient; it can be dangerous. In the United States, more than 600 people die from extreme heat every year, and that number could climb because of the effects of climate change. If everyone cranks up their air conditioning or turns on fans, the grid — which shuttles our electricity from place to place — can short-circuit, putting millions at risk—from hospitals, grocery stores, to nursing homes, and even our schools.

One of the biggest ways our grid avoids short-circuiting? Water batteries.

(Pumped-storage hydropower is the most dominant form of energy storage on the electric grid today. It also plays an important role in bringing more renewable resources on to the grid.)

Also known as pumped storage hydropower, water batteries are made of two big pools of water, one high above the other, that act like an hourglass to provide power. They’re some of the biggest batteries on Earth, and that’s just one of many reasons we love pumped storage hydropower — and you should too!

In honor of National Hydropower Day on August 24, here are 10 reasons to appreciate how important — and powerful — water batteries are, and why we need to continue investing in these important resources across the country.

  1. Grid overload? Thanks to water batteries, it’s rare. When other energy sources like solar and wind make more electricity than nearby homes need, that extra power pushes water up into the water battery’s top pool where it waits, “charging” the water battery. Then, when needed—like during a grid-gutting heat wave — the water is released from that top pool and flows down, spinning a turbine that creates electricity to power your lights, refrigerator, or other essentials.
  2. Mother nature is no problem for water batteries. Renewable energy is crucial for a clean energy future, but sometimes, mother nature makes it challenging. Water batteries can fill energy gaps on cloudy and still days, making sure clean energy is still reliable energy.
  3. Pumped storage hydropower provides 93% of U.S. energy storage. Pumped storage hydropower projects are some of the biggest long-term energy storage systems around today. You might have yet to see this invisible force, but it’s helping to power the world around you.
  4. The United States of water batteries — in 2021, 18 states and all major regions of the country use pumped storage hydropower to store energy. California, Virginia, and South Carolina get the most out of these clean energy pools, and three new states have projects in progress (which will bring the total up to 21).
  5. In the United States, pumped storage hydropower can store up to 553 gigawatt-hours of energy. That could power video gaming across the entire country for about a week. Every year, American video gamers use about as much energy as 85 million refrigerators or 5 million cars.
  6. Pumped storage is the most efficient large energy storage system currently available — clocking in at 70-80%! Because it takes energy to store energy, no storage system — not even typical batteries — are 100% efficient. Pumping water into a water battery’s top reservoir requires a burst of energy. Still, a good 80% of what goes up, comes back down.
  7. Hydropower and pumped storage facilities provide 40% of the power needed to jumpstart a grid after a blackout. Ice storms, wildfires, and even hackers could stop the electric grid from powering our homes and offices. When emergencies knock out other energy sources, water batteries can turn on fast to keep people safe and comfortable.
  8. Natural disasters are no match for hydropower and pumped storage’s flood control and irrigation benefits! Water batteries can save you from those, too — they help absorb that extra water and use it to power your home (or help put out those wildfires that can harm the grid). The pools of water can also give clean water to crops, and you, too, making sure you don’t go thirsty during a heatwave.
  9. U.S. pumped storage hydropower grew without any new construction. How does that work? Through “capacity increases” or upgrades to facilities that make them more powerful. From 2010 to 2019, upgrades at just six pumped storage facilities led to 1,400 MW in capacity increase for U.S. pumped storage. That means that within the capacity of U.S. pumped storage — without any new construction — pumped storage grew by almost as much as all other types of energy storage combined.
  10. Water batteries are almost a century old. 90 years in fact. The first U.S. water battery — dubbed the 10-mile storage battery — popped up in Connecticut in 1930. Almost a century later, water batteries still provide energy at a low price. Here’s to the next 90!

Stig drifts 2,000 hp electric Ford Supervan around Top Gear test track [video]

Stig drifts 2,000 hp electric Ford Supervan around Top Gear test track [video]

The Top Gear TV show might be over, but its tamed racing driver – a masked, anonymous hot shoe known only as “the Stig” – lives on … and his latest adventure involves pitching the 1,400 hp electric Ford SuperVan demonstration vehicle around the famed Top Gear test track. Sideways.

Whether we’re talking about record lap times at hallowed motorsports grounds like Bathhurst or the Hillclimb at the Goodwood Festival of Speed, we’ve been covering the 1,400 hp SuperVan project for some time – but the big boxy Transit-ish racing van with hypercar-slaying performance never seems to get boring.

In this video from the official Top Gear YouTube channel (is Top Gear just a YouTube show, now?), the boxy Ford racer seems to have sprouted an additional 600 peak horsepower in its latest “4.2” iteration, for a stout 2,000 hp total. For his (?) part, the Stig puts all of those horses to work in what appears to be a serious attempt to take the overall track record.

I won’t spoil the outcome for you, but suffice it to say that even the most die-hard anti-EV hysterics will have to admit that SuperVan is a seriously quick machine.

SuperVan 4.2: How fast can a 2000 hp transit go?

[SPOILERS AHEAD] Even with 2,000 hp, instant torque, and over 4,000 lbs. of aerodynamic downforce, the SuperVan wasn’t able to beat the long-standing 1st and 2nd place spots held by the Renault R24 (a legit Formula 1 race car) and the Lotus T125 Exos (a track-only special that sure looks like a legit Formula 1 race car), but after crossing the line with a time of 1:05.3, the Ford claims third place on the overall leaderboard.

That 3rd place is likely to be a permanent spot on Top Gear‘s leaderboard, as well – as the track itself is likely to be demolished somewhat sooner than later.

You can check out the video (above) and watch the whole segment for yourself, or just skip ahead to the eight-minute mark to watch the tire-shredding sideways action promised in the headline. If you do, let us know what you think of Ford’s fast “van” in the comments.

First autonomous electric loaders in North America get to work

Swedish multinational Sandvik says it’s successfully deployed a pair of fully autonomous Toro LH518iB battery-electric underground loaders at the New Gold Inc. ($NGD) New Afton mine in British Columbia, Canada.

The heavy mining equipment experts at Sandvik say that the revolutionary new 18 ton loaders have been in service since mid-November, working in a designated test area of the mine’s “Lift 1” footwall. The mine’s operators are preparing to move the automated machines to the mine’s “C-Zone” any time now, putting them into regular service by the first of the new year.

“This is a significant milestone for Canadian mining, as these are North America’s first fully automated battery-electric loaders,” Sandvik said in a LinkedIn post. “(The Toro LH518iB’s) introduction highlights the potential of automation and electrification in mining.”

The company says the addition of the new heavy loaders will enable New Afton’s operations to “enhance cycle times and reduce heat, noise and greenhouse gas emissions” at the block cave mine – the only such operation (currently) in Canada.

From drilling and rigging to heavy haul solutions, companies like Sandvik are proving that electric equipment is more than up to the task of moving dirt and pulling stuff out of the ground. At the same time, rising demand for nickel, lithium, and phosphates combined with the natural benefits of electrification are driving the adoption of electric mining machines while a persistent operator shortage is boosting demand for autonomous tech in those machines.

The combined factors listed above are rapidly accelerating the rate at which machines that are already in service are becoming obsolete – and, while some companies are exploring the cost/benefit of converting existing vehicles to electric or, in some cases, hydrogen, the general consensus seems to be that more companies will be be buying more new equipment more often in the years ahead.

What’s more, more of that equipment will be more and more likely to be autonomous as time goes on.

We covered the market outlook for autonomous and electric mining equipment earlier this summer, and I posted an episode exploring the growing demand for electric equipment on an episode of Quick Charge I’ve embedded, below. Check it out, then let us know what you think of the future of electric mining in the comments.

More EVs means more mines, equipment

Contargo logistics adds 20 Mercedes eActros 600 electric semis to fleet

European logistics firm Contargo is adding twenty of Mercedes’ new, 600 km-capable eActros battery electric semi trucks to its trimodal delivery fleet, bringing zero-emission shipping to Germany’s hinterland.

With over 300 miles of all-electric range, the new Mercedes eActros 600 electric semi truck was designed for (what a European would call) long-haul trucking. Now, after officially entering production at the company’s Wörth plant in Bavaria last month, the eActros 600 is reaching its first customer: Contargo.

With the addition of the twenty new Mercedes, Contargo’s electric truck fleet has grown to 60 BEVs, with plans to increase that total to 90. And, according to Mercedes, Contargo is just the first.

The German truck company says it has plans to deliver fifty (50) of the 600 kWh battery-equipped electric semi trucks to German shipping companies by the close of 2024.

Contargo’s 20 eActros 600 trucks were funded in part by the Federal Ministry for Digital Affairs and Transport as part of a broader plan to replace a total of 86 diesel-engined commercial vehicles with more climate-friendly alternatives. The funding directive is coordinated by NOW GmbH, and the applications were approved by the Federal Office for Logistics and Mobility.

Electrek’s Take

Holcim, a global leader in building materials and solutions, has recently made a significant commitment to sustainability by placing a purchase order for 1,000 Mercedes electric semi trucks.

Electric semi trucks are racking up millions of miles in the US, and abroad. As more and more pilot programs begin to pay off, they’re going to lead to more orders for battery electric trucks and more reductions in both diesel demand and harmful carbon emissions.

We can’t wait to see more.
