With declining technology costs and increasing renewable deployment, energy storage is poised to be a valuable resource on future power grids — but what is the total market potential for storage technologies, and what are the key drivers of cost-optimal deployment?

In the latest report from the Storage Futures Study (SFS), Economic Potential of Diurnal Storage in the U.S. Power Sector, NREL analysts Will Frazier, Wesley Cole, Paul Denholm, Scott Machen, and Nate Blair, describe significant market potential for utility-scale diurnal storage (up to 12 hours) in the U.S. power system through 2050. They found storage adds the most value to the grid and deployment increases when the power system allows storage to simultaneously provide multiple grid services and when there is greater solar photovoltaic (PV) penetration.

“We find significant market potential for diurnal energy storage across a variety of modeled scenarios, mostly occurring by 2030,” said Will Frazier, National Renewable Energy Laboratory (NREL) analyst and lead author of the report. “To realize cost-optimal storage deployment, the power system will need to allow storage to provide capacity and energy time-shifting grid services.”

The SFS — led by NREL and supported by the U.S. Department of Energy’s (DOE’s) Energy Storage Grand Challenge — is a multiyear research project to explore how advancing energy storage technologies could impact the deployment of utility-scale storage and adoption of distributed storage, including impacts to future power system infrastructure investment and operations.

Expanded Capabilities to Model Storage Potential

For this work, researchers added new capabilities to NREL’s Regional Energy Deployment System (ReEDS) capacity expansion model to accurately represent the value of diurnal battery energy storage when it is allowed to provide grid services — an inherently complex modeling challenge. Cost and performance metrics focus on Li-ion batteries because the technology has more market maturity than other emerging technologies. Because the value of storage depends greatly on timing, ReEDS simulated system operations every hour.

NREL researchers used ReEDS to model two sets of scenarios — one that allows storage to provide multiple grid services and one that restricts the services that storage can provide. All the scenarios use different cost and performance assumptions for storage, wind, solar PV, and natural gas to determine the key drivers of energy storage deployment.

Installed Storage Capacity Could Increase Five-Fold by 2050

Across all scenarios in the study, utility-scale diurnal energy storage deployment grows significantly through 2050, totaling over 125 gigawatts of installed capacity in the modest cost and performance assumptions — a more than five-fold increase from today’s total. Depending on cost and other variables, deployment could total as much as 680 gigawatts by 2050.

“These are game-changing numbers,” Frazier said. “Today we have 23 gigawatts of storage capacity, all of which is pumped-hydro.”

Initially, the new storage deployment is mostly shorter duration (up to 4 hours) and then progresses to longer durations (up to 12 hours) as deployment increases, mostly because longer-duration storage is currently more expensive. In 2030, annual deployment of battery storage ranges from 1 to 30 gigawatts across the scenarios. By 2050, annual deployment ranges from 7 to 77 gigawatts.

System Flexibility Key to Storage Deployment

To understand what could drive future grid-scale storage deployment, NREL modeled the techno-economic potential of storage when it is allowed to independently provide three grid services: capacity, energy time-shifting, and operating reserves.

  • Blue — Energy Time-Shifting & Operating Reserves (No Firm Capacity From Storage)
  • Black — Firm Capacity & Energy Time-Shifting (No Operating Reserves From Storage)
  • Green — Firm Capacity & Operating Reserves (No Energy Time-Shifting From Storage)

NREL found not allowing storage to provide firm capacity impacts future deployment the most, although not allowing firm capacity or energy time-shifting services can also substantially decrease potential deployment. Operating reserves, on the hand, do not drive the deployment of storage within the study because they find limited overall market potential for this service.

Storage and Solar Symbiosis

Multiple NREL studies have pointed to the symbiotic nature of solar and storage, and this study reinforces that relationship. More PV generation makes peak demand periods shorter and decreases how much energy capacity is needed from storage — thereby increasing the value of storage capacity and effectively decreasing the cost of storage by allowing shorter-duration batteries to be a competitive source of peaking capacity. NREL found over time the value of energy storage in providing peaking capacity increases as load grows and existing generators retire.

Solar PV generation also has a strong relationship with time-shifting services. More PV generation creates more volatile energy price profiles, increasing the potential of storage energy time-shifting. Like peaking capacity, the value of energy time-shifting grows over time with increased PV penetration.

Next Up in the Storage Futures Study

The SFS will continue to explore topics from the foundational report that outlines a visionary framework for the possible evolution of the stationary energy storage industry — and the power system as a whole.

The next report in the series will assess customer adoption potential of distributed diurnal storage for several future scenarios. The study will also include the larger impacts of storage deployment on power system evolution and operations.

With glowing reviews, RIZON could soon be the #1 truck in the #2 business

Portable bathroom company Diamond Environmental showcased its new, all-electric RIZON medium duty commercial truck at a San Marcos, California mobility event last month – and the verdict is in: these electric trucks don’t stink!

City officials from San Marcos attended the electric vehicle and sustainability-focused event, including San Marcos Mayor Rebecca Jones, San Diego Land Policy Advisor Hunter McDonald, and councilman Ed Musgrove. The stars of the show, however, were Diamond Environmental’s four RIZON e18L medium-duty commercial EVs.

“RIZON trucks are perfect for our daily local operations and align with our environmental and sustainability goals,” explained Alex Fortunati, CEO of Diamond Environmental. “Thanks to San Diego County’s incentive programs, we could economically make the transition to electromobility.”

Diamond Environmental equipped their RIZON electric trucks with stake bed/flatbed style bodies for two of the trucks, enabling a wide range of versatility for transporting portable toilet facilities, sinks, and other sanitation supplies to construction job sites and outdoor events like the Super Bowl in San Diego and the Coachella Music Festival.

For their part, the RIZON seems genuinely excited for the high-visibility partnership with Diamond Environmental.

“We’re pleased to support Diamond Environmental in their transition to zero-emissions RIZON trucks, enhancing both convenience and flexibility in their operations. Our sales team collaborated closely with them throughout the selection process to customize trucks that perfectly meet their business needs,” said Alex Voets, General Manager of RIZON USA. “We are proud to contribute to the innovations in today’s electric truck market, driving towards a more sustainable future for our communities.”

The RIZON offers fast-charging options for its 124 kWh battery pack, including DCFC up to 104 kW and Level 2 AC up to 14.9 kW, minimize downtime for the company’s daily delivery routes, achieving a range of up to 160 miles on a single charge. More than enough, in other words, to handle whatever loads Diamond Environmental will dump on it.

Funding for the trucks came, in part, from the Innovative Small e-Fleet (ISEF) Program that offers qualifying small fleets a minimum voucher of $120,000 toward an all-electric Class 4-5 electric truck, as well as region-specific incentives, like the San Diego County Air Pollution Control District’s grant program.

Electrek’s Take

There’s a total place in the North American market for an agile, easy-to-drive medium duty truck like the RIZON, and Daimler’s nationwide network of Freightliner and Western Star dealers should give first time MD buyers a bit more peach of mind than they might get from a startup brand.

Farmrobo iMog hopes to bring autonomous tractor to hobby farms

Developed by Indian company Farmrobo Technologies, the iMog is a fully autonomous, multipurpose electric farm tractor designed to be a cost-effective solution to support small-scale farming operations and hobby farms.

In constant development since 2019, the Farmrobo iMog weights in at “just” 550 lbs., and is just two feet wide and four feet long. That’s small enough to allow it to easily fit between tightly-packed rows of crops without damaging them. The robot’s small size also makes it pretty efficient – its 8 HP electric motor can run for up to 5 hours on its relatively small 90 AH LFP battery (about 4 kWh, assuming a 48V system).

The robot uses RTK-enabled GPS, which stands for “Real-Time Kinematic Global Positioning System.” RTK-enabled GPS combines standard GPS signals with real-time correction data from local base stations, delivering what the company calls “centimeter-level positioning accuracy.” The robot can then be programmed to operate on a given route or path by the farmer, or operated remotely via on-board cameras.

The iMog also features an innovative Power Take-Off (PTO) system that allows it to power a range of conventional attachments that includes a roto-tiller, high-tech sprayer, a mulcher, and more. The base robot retails for €12,000 and is available in India, the Middle East, and (now) in Europe.

As I write this, Farmrobo claims 20 examples of its iMog robot tractor are currently in operation, with many more on their way to customers.

Electrek’s Take

Y’all know I love a good electric tractor, but while the North American market seemingly wants to go bigger and badder than even Solectrac’s 25 HP machines, it seems the rest of the world understands that the biggest tool for the job isn’t always the right tool for the job.

Here’s hoping the Farmrobo team has better luck than Solectrac.

Awesomely Weird Alibaba EV of the Week: A $7,000 armored golf cart?

Awesomely Weird Alibaba EV of the Week: A ,000 armored golf cart?

What would you get if you created the illegitimate love child of a Mercedes G-Wagon and a Brinks armored truck (and perhaps if the Mercedes chain-smoked through the pregnancy)? I think you’d wind up with something like the wacky-looking electric cart that has earned the dubious honor of being named this week’s Awesomely Weird Alibaba Electric Vehicle of the Week!

I’m not sure this is exactly an armored golf cart, so I wouldn’t invite any unnecessary potshots while cruising your hood, but I’m at a loss of how else to describe it.

It’s definitely not a “real” car, as evidenced by its US $6,999 price tag and the 30 km/h (18 mph) top speed. If you ask me though, that speed goes in the ‘advantages’ column. When you drive something that looks this good, you want to be going slow enough to give people a good, long look.

A vehicle like this is designed to send a statement. Unfortunately, I think that statement might be, “I wanted a Jeep but my spouse wanted to remodel the kitchen.”

So if it’s not a real car, then what is it?

Measuring a stubby 306 cm long (an entire half inch over 10 feet), this four-seater mini-SUV is less G-Wagon and more “Oh, gee” wagon. It can supposedly carry up to 370 kg (815 lb) in passengers or cargo, but there’s no telling how much of a dent that puts in the already challenged top speed.

Safety might also be a passing concern. It doesn’t have any seatbelts, but the tires look like they just about extend out past the front and rear, so at least you’ve got some nice shock-absorbent bumpers built into the design.

The advertisement claims a maximum range of up to 80 km (50 miles) per charge, which seems like several more miles than anyone needs from something like this.

There’s no word on battery technology, which means I’m assuming either features older lead acid tech or there’s a frunk full of lemons and a bunch of loose wires running through the firewall.

I’m glad to see that the roof rack is at least equipped with enough LED lights to make an airport runway jealous, just in case I find myself stuck in the wilds of my backyard after dark. And that roof rack even looks pretty heavy-duty, though since the cart is considerably taller than it is wide, tight turns with a heavily-loaded roof rack should probably be avoided.

As much as I love this thing, I don’t think I’ll be whipping out my credit card any time soon.

Don’t get me wrong, I’ve bought plenty of bad ideas on Alibaba before. But since my $2,000 electric truck ending up costing me nearly 4x that much by the time it landed in the US, I’m a bit worried what the final price tag on a $6,999 Mini-MegaOverlander would become.

I don’t recommend anyone actually try buying this cute little TinyTrailblazer either, and I’m certainly not vouching for the vendor, who I discovered by chance while scrolling through Alibaba to procrastinate real work. Keep in mind that this is all part of a tongue-in-cheek column I write, diving into the depths of Alibaba’s weird and funny collection of awesome electric vehicles.

But hey, if someone does go that route, it wouldn’t be the first time my advice has been ignored and some awesome photos have landed in inbox several months later. Just don’t say I didn’t warn you if it turns out some Nigerian prince has your last paycheck and you’re up a creek with no MicroMudder to come bail you out!
