The Storage Futures Study (SFS) was launched in 2020 by the National Renewable Energy Laboratory and is supported by the U.S. Department of Energy’s (DOE’s) Energy Storage Grand Challenge. The study explores how energy storage technology advancement could impact the deployment of utility-scale storage and adoption of distributed storage, as well as future power system infrastructure investment and operations.

There is economic potential for up to 490 gigawatts per hour of behind-the-meter battery storage in the United States by 2050 in residential, commercial, and industrial sectors, or 300 times today’s installed capacity. But only a small fraction could be adopted by customers, according to the latest phase of the National Renewable Energy Laboratory’s (NREL’s) Storage Futures Study.

“By implementing new battery capabilities in our model, we were able to do scenario comparison that revealed battery cost and the value of backup power are important drivers of distributed storage deployment,” said Ashreeta Prasanna, lead author of the NREL technical report, Distributed Solar and Storage Outlook: Methodology and Scenarios.

The study provides one of the first published estimates of distributed battery storage deployment. The NREL team of analysts — also including Kevin McCabe, Ben Sigrin, and Nate Blair — modeled customer adoption of battery storage systems coupled with solar photovoltaics (PV) in the United States out to 2050 under several scenarios. The results can help inform planning for technical grid infrastructure to capture the benefits and mitigate the challenges of growing distributed electricity generation.

PV-Plus-Battery Scenarios

The Rise of Behind-the-Meter Battery Storage

A widespread transition to distributed energy resources (DERs) is taking place. Households and businesses around the world are adopting DERs to lower their energy bills and curb carbon emissions. Local policymakers have set ambitious energy and climate goals; grid resiliency is a growing concern due to climate change and weather disasters; and more communities face high energy burdens.

In addition, Federal Energy Regulatory Commission Order 2222 enables DERs to participate alongside traditional energy resources in regional organized wholesale markets.

All these factors have contributed to a rise in DER deployment, including batteries. With declining battery storage costs, customers are starting to pair batteries with distributed solar. Behind-the-meter battery capacity totaled almost 1 gigawatt in the United States by the end of 2020, according to Wood Mackenzie.

While DERs offer many benefits to customers and the grid, like peak load shifting, integrating these resources into the power system presents complex challenges for electric utilities. “The transmission system wasn’t designed with distributed generation in mind,” said Ben Sigrin, coauthor of the report. “Projected DER adoption potential can provide a window into distributed generation and help inform future power system planning.”

Bottom-up Modeling for Bottom-up Generation

NREL’s open-source Distributed Generation Market Demand (dGen) model simulates customer adoption of distributed solar, wind, and storage using a bottom-up, agent-based approach and spatially resolved data (watch a Super Mario Bros.-inspired video to learn more).

For this phase of the Storage Futures Study, the model was modified to simulate the technical, economic, and market potential of behind-the-meter battery storage.

dGen interoperated with NREL’s System Advisor Model (SAM), which simulates the performance and efficiency of energy technologies, including cash flow analysis to calculate payback periods — an important consideration in a customer’s decision to adopt a technology.

By interfacing with SAM, dGen modeled the cost-effectiveness and customer adoption of PV-plus-battery storage systems for residential, commercial, and industrial entities in the United States with different technology costs, storage valuation, incentives, and compensation. The resulting upper and lower bounds of adoption revealed what customers consider most in their decisions.

Lower Battery Costs, High Backup-Power Value Drives Deployment

Across all 2050 scenarios, dGen modeled significant economic potential for distributed battery storage coupled with PV. Scenarios assuming modest projected declines in battery costs and lower value of backup power show economic potential for 114 gigawatts of storage capacity — a 90-times increase from today. When battery costs significantly reduce and the value of backup power doubles, the economic potential increases to 245 gigawatts.

However, only 7% of the estimated capacity is adopted by customers. The difference is largely due to the long payback period for distributed PV-plus-battery storage systems, which averages 11 years for the residential sector, 12 years for the commercial sector, and 8 years for the industrial sector in 2030.

“The estimated adoption potential translates to less than 20% of the market potential,” Prasanna said. “Customers are less inclined to invest in a system that takes a long time to be profitable.”

Modeled deployment varies by location based on specific rate structures or incentive programs but is generally driven by battery cost and the value of backup power. Similar trends are seen on the national scale, where lower battery costs and high backup-power value increase deployment.

PV and Batteries Drive Each Other’s Adoption

Several findings in the study demonstrate that PV and batteries make an economical pairing. Because an average PV-plus-battery storage system is larger than PV-only configurations, battery storage increases the PV capacity and the system’s economic value.

About 34%–40% of total annual PV installations projected in 2050 in the reference or baseline scenario are coadopted with batteries. This rate, again, is driven by higher value of backup power and lower technology costs.

Combined cost reductions in both PV and battery storage technologies drive additional adoption compared to cost reductions in just battery technology alone. When costs decrease for both technologies, more customers adopt PV-plus-battery systems, and deployment increases by 106% in 2050.

“The process of developing and implementing the distributed storage technology within dGen revealed additional questions and needed research capabilities related to behind-the-meter battery storage adoption,” Prasanna said. “Additional enhancements of dGen will be needed to explore research questions such as projecting the adoption of community-scale DERs and storage capacity and their impact on the distribution grid, exploration of the tradeoffs between distributed and utility-scale storage, and the role of DERs in supporting the transition to a decarbonized economy.”

BYD is offering free car insurance on select EVs in new end-of-year sales promo

China’s EV leader wants to close the year strong with a new sales promotion. BYD is now offering free car insurance on certain EVs ahead of the upcoming Chinese New Year. Will it be enough to take the global EV sales crown in 2024?

BYD offers free insurance on some EVs to boost sales

With a record 506,804 NEVs (EV and PHEV models) sold in November, BYD has now had two straight months with over 500,000 in vehicle sales.

The EV giant has no plans to slow down. On Thursday, BYD announced its latest “New Year GO New Car” sales promotion on its Weibo page.

From today, December 26, 2024, through January 26, 2025, BYD is offering free car insurance on select PHEVs and EVs in its Ocean and Dynasy lineups. The promo includes several top-selling EVs, including the Dolphin, Seal, and Sea Lion 07.

Through the first 11 months of 2024, BYD sold nearly 3.76 million NEVs, including 1.56 million all-electric models. The promo comes as BYD is in a tight race with Tesla for the global EV sales crown for 2024.

Through September, Tesla delivered 1.3 million EVs compared to BYD’s 1.17 million. Since Tesla doesn’t report monthly sales numbers, we will have to wait until the end-of-year numbers come out to determine who will take the EV sales crown in 2024.

The Seagull EV, BYD’s cheapest electric car starting under $10,000, was once again China’s best-selling vehicle last month after topping the Tesla Model Y. BYD sold 56,156 Seagull EVs last month alone in China.

Although the global EV sales race between BYD and Tesla is heating up into the end of the year, the Chinese EV leader is quickly outselling some of the largest global automakers.

BYD sold more vehicles globally than Nissan and Honda in the third quarter, and it is now closing in on Ford.

The rate at which China has rebuilt its car industry is truly staggering

The rate at which China has rebuilt its car industry is truly staggering

After starting off slow, China’s EV industry has reorganized itself in record time, going from a global laggard to a global leader in about 5 years – showing other countries how it ought to be done.

In 2020, China was still early in its EV transition, lagging behind many other countries and regions. With EVs only consisting of 5.4% of the country’s car market, it lagged behind California and almost all of Europe – even the slower-adopting countries, like Romania. It was only barely ahead of the 4.6% global average that year.

It set a relatively unambitious goal of 50% EV sales by 2035 – and those 50% didn’t even need to be gasoline-free, they could be hybrids or plug-in hybrids which still have a gas engine inside (what China classifies as “New Energy Vehicles” or NEVs). Around that time, both California and Europe were thinking about banning gas car sales by 2035 – and each of those targets probably could have been earlier, too.

Now, with 2025 coming in just a week, China is likely to hit that 2035 target ten years early – closer to the year that it set the target than the year that the target was set for. It even moved its target forward to 45% NEVs by 2027 this January… and exceeded that target within less than a year.

It’s an indication of how much China is able to do when they put their minds to it – and how other countries have completely failed to keep up due to bickering and resistance from companies or governments being hostile to better technology.

The rapid rise in Chinese EVs

2020 was a turning point for the Chinese EV industry. China responded strongly to the start of the COVID-19 pandemic (and as a result, had a lower death rate than almost any country, despite life within China being relatively normal after initial lockdowns), which meant a large drop in vehicle sales in the country (much like the rest of the world).

But when sales recovered, China’s eyes had turned inwards. Not only had domestic EV makers started to ramp up production rates and quality (after a decade of smart industrial policy focusing on mineral supply and encouraging domestic manufacturers), but the rest of the world had spent years blaming China for all sorts of ills (like carbon emissions, which China was criticized for not doing enough about, and now is criticized for doing too much). Technology blockades and discussions about tariffs led to consumer nationalism, with Chinese consumers expressing interest in domestic goods more than they had before.

This, coupled with new emissions rules that the rest of the world’s automakers hadn’t prepared properly for (despite having 7 years notice) led to a glut in gas car supply – mostly from foreign brands – which we called the “canary in the coal mine” for where the global ICE car market was going.

Chinese auto dealers could have responded to this by asking the government to reverse the rules, but instead they asked for (and were granted) a six month amnesty in order to clear unsold cars off of their lots, and otherwise demanded that auto manufacturers shape up and build EVs faster.

As a result of this mentality, China became the top global exporter of automobiles this year – a title that Japan had for decades.

Meanwhile, the West drags its feet

It’s a stark difference to how automakers and governments usually behave in the West (and in Japan), working to slow down transitions and add protectionist measures instead of gearing up for an inevitable change in the industry that already started.

And the regressive portions of Western governments are all too happy to oblige, with for example the US republicans promising to hold the US auto industry back even further, ensuring it isn’t ready for the present, and their far-right ilk in European governments arguing for similar measures.

President Biden’s administration did do its part to try to turn US industrial policy around to be ready for EVs with the excellent Inflation Reduction Act, which brought hundreds of billions in investment and hundreds of thousands of EV jobs to the US. Biden’s EPA and DOT also improved several emissions rules (despite softening them somewhat after industry pressure) to move the industry forward. But it also implemented large tariffs, which could help to breed complacency.

But unfortunately for America, the next occupant of the White House is convicted felon Donald Trump, who finally received more votes than his opponent on his third attempt (despite committing treason in 2021, for which there is a clear legal remedy), with less than half of the country voting to ensure that US manufacturing fall further behind.

In his last stint squatting in the White House, the EPA knowingly worked against clean air and instead of preparing the US to lead the EV transition, it focused on petty losing squabbles with states that are actually trying to move the US forward. We could have had smarter industrial policy, like China, but instead government worked to shatter the regulatory certainty that President Obama had helped to lay out.

Luckily, most Western auto manufacturers may have learned their lessons, and this time they’re finally asking government not to blow up emissions rules. They recently donated money to the famous narcissist, presumably hoping to get in his ear – we’ll have to wait and see whether what they say is actually geared towards the future (and whether the ignoramus they’re saying it to is even able to comprehend it). Though that could all be for naught, because one of Mr. Trump’s closest allies is Elon Musk, CEO of the largest EV maker in the US, who has confusingly focused his advocacy on harming EVs.

Change is coming faster than you think

China’s rapid rise in EV sales, meeting targets well ahead of schedule, may seem anomalous at first blush. It’s not often that a target gets met in one third of the time allotted for it, especially when you’re dealing with a country of 1.5 billion people. That’s a lot of inertia to turn around.

But there are other examples of targets getting met and exceeded early, and companies and governments need to be aware of these and maintain flexibility instead of fighting in the face of positive change.

Norway is one example, where the country was already far ahead of the international community, and set a target to end gas car sales by 2025. While there are still a trickle of non-EVs sold in the country, Norway’s market was already over 90% electrified in 2021.

This is not uncommon with technology adoption curves, as once a technology reaches a critical mass, most consumers consider it the default and will switch to it without much issue. That critical mass has already been met in most Northern European countries and in China, but other places could get there fast.

Once they do, who do you think will come out for the better – the countries and companies whose manufacturing base is ready to supply products that fuel that change, or the ones that have spent decades bickering and trying to slow it down so they can continue spewing poison in all of our lungs?

And as I’ve ended several articles in recent years: we should have been doing more earlier, but as the famous (possibly Chinese) proverb says, “the best time to plant a tree is 20 years ago, the second best time is today.”

Kia's new Syros SUV is going electric as a low-cost Hyundai Inster EV twin

Kia introduced its new Syros SUV last week. Although it was launched with a gas-powered engine, Kia plans to launch the all-electric version soon. The new Kia Syros EV will share underpinnings with the Hyundai Inster EV as its latest low-cost electric model.

What we know about the upcoming Kia Syros EV

India’s EV market is expected to surge over the next few years. In 2024, the India EV market is projected to be valued at around $24 billion. That number is expected to reach nearly $118 billion by 2032.

Kia is looking to take advantage of the transition. After launching its first vehicle (Seltos) in India in 2019, Kia is already one of the top 10 auto manufacturers in the region.

The Korean auto giant has added several models to its lineup, including the Sonet, Carnival, Caren, and electric EV6 and EV9 SUVs.

Just last week, the Kia Syros made its global debut. Kia calls the compact SUV “revolutionary,” but there’s one problem: it only has two gas-powered engine options. That will soon change. According to Autocar India, Kia will launch the Syros EV in India in early 2025.

Although no other details were confirmed, the Kia Syros EV will share its K1 platform with the Hyundai Inster EV. Hyundai’s compact electric crossover has two battery options, 42 kWh and 49 kWh, good for 300 km (186 mi) to 355 km (220 mi) range on the WLTP cycle.

In Europe, the Inster EV starts at around $30,000. In Korea, the electric crossover is known as the Casper Electric, and prices, including incentives, start around $20,000.

Kia’s new electric SUV is expected to start in the price range of Rs 15 lakh-20 lakh (ex-showroom), or around $17,500 to $23,500.

Despite the difference in powertrain, the electric version is expected to have the same styling and features as the gas-powered models. Kia expects between 50,000 and 60,000 in sales between the upcoming electric Carens and Syros EV models by 2026.

The company is launching a series of more affordable, mass-market EVs globally, including the EV3, EV4, and EV5, to secure its spot in the industry as it shifts to electric vehicles.
