California-based Rondo Energy and Thailand’s Siam Cement Group are going to operate the world’s largest battery factory in Thailand.
The world’s largest battery factory
The production capacity of Rondo Heat Battery storage at Siam Cement Group’s factory is going to be ramped up from 2.4 GWh to 90 GWh per year – that’s larger than any existing or planned battery manufacturing factory worldwide.
The existing 160,000 square meters (1.72 million square feet) factory is going to be expanded. A spokesperson told Electrek that the launch timeline is over the next few years, but the two companies have not yet committed to a set date.
The 90 GWh of planned capacity will result in 12 million tons of CO2 emissions savings annually, equivalent to removing over 4 million ICE vehicles from the road each year.
How the Rondo Heat Battery works
Siam Cement Group is the largest and oldest cement building material company in Southeast Asia. Its subsidiary SRIC produces refractory bricks. Also called fire bricks, refractory bricks are made of fireproof materials that can withstand high temperatures.
Each brick that Siam Cement Group makes for Rondo’s batteries (pictured above) is 500 kg and stores 100 kWh – as much as a Tesla Model X.
Rondo Energy, which is backed by Bill Gates-founded Breakthrough Energy Ventures and utility-backed Energy Impact Partners, launched its first commercial operating unit at an ethanol plant in Pixley, California, in March.
The Rondo Heat Battery captures intermittent electricity from solar and wind, stores the energy from that electricity as high-temperature heat in brick materials, and delivers the stored energy on demand as high-temperature heat and/or electricity:
The battery is made only of brick and iron. It charges in as little as four hours and stores heat energy at temperatures up to 1500° C for hours or days, delivering zero-carbon heat for such processes as steel, cement, and chemical manufacturing.
Rondo has designed its battery for such industries as steel, cement, grid energy storage, power plant conversion, and mining.
Here’s how Rondo says its batteries can reduce emissions in different sectors:
Raymond James energy analyst Pavel Molchanov said in a statement:
Electric thermal energy storage can play a useful role in addressing the needs of the industrial sector, which has been slow to decarbonize.
And, from an energy security standpoint, it is worth noting that this technology avoids the use of scarce and expensive materials.
Industry uses more energy than any other sector in the world, and most industrial energy is used as heat. Industrial heat consumes a quarter of total world energy and today releases a quarter of the world’s carbon dioxide emissions.

A former coal mine in western Maryland is now generating solar power – and it’s the largest solar farm in the state. Competitive Power Ventures (CPV) has brought Maryland’s largest solar project online in Garrett County, turning reclaimed coal mine land into a source of clean electricity.
CPV Renewable Power, an affiliate of CPV, and investment partner Harrison Street Asset Management have started commercial operations at CPV Backbone Solar, a 160-megawatt solar project in western Maryland. The site sits on a reclaimed, decommissioned coal mine, turning previously disturbed land into a new source of clean power.
Construction of the project was handled by Vanguard Energy Partners, a solar engineering, procurement, and construction firm.
The project comprises approximately 324,000 solar panels and is expected to generate enough electricity to power around 30,000 homes. For Maryland, it adds new in‑state generation while giving former fossil fuel land a second life.

CPV says that the project aims to demonstrate the role of brownfield redevelopment in the energy transition. The company’s CEO, Sherman Knight, said Backbone Solar shows “how brownfield redevelopment, innovative engineering, and strategic partnerships can meet complex project challenges and deliver new power generation in Maryland.”
Local officials have welcomed the project. Garrett County Board Chairman Paul Edwards said bringing the solar facility to the county helps protect the region’s natural landscape while also creating economic value for local residents.
CPV Backbone Solar also includes a community and environmental investment tied to the project. CPV has committed $100,000 over four years to the Deep Creek Watershed Foundation.
Backbone Solar becomes part of CPV’s growing renewable portfolio, which includes four operating wind and solar projects. The company also says it has a 4.8-gigawatt renewable development pipeline.
A second phase of the Backbone Solar project is already under construction. Once completed, it’s expected to increase the site’s total installed capacity from 160 MW to 175 MW.

U.S. President Donald Trump makes an announcement about the Navy’s “Golden Fleet” at Mar-a-lago in Palm Beach, Florida, U.S., December 22, 2025.

President Donald Trump on Monday said the U.S. will keep crude oil and tankers seized near Venezuela.
“We’re going to keep it,” Trump told reporters in Palm Beach, Florida after unveiling a new class of battleships named after himself.
“Maybe we’ll sell it, maybe we’ll keep it, maybe we’ll use it in the strategic reserve,” Trump said of the seized oil. “We’re keeping the ships also.”
Trump has ordered a blockade of sanctioned oil tankers entering or leaving Venezuela as he escalates pressure on President Nicolas Maduro.
The U.S. seized a large tanker on Dec. 10 that was carrying more than 1 million barrels of oil, according energy consulting firm Kpler. It intercepted a second vessel over the weekend. Trump confirmed Monday that the U.S. is pursuing a third tanker.
“It’s moving along. We’ll end up getting it,” Trump said of the tanker. “It came from the wrong location. It came out of Venezuela, and it was sanctioned.”
Trump said “it would be smart” for Maduro to step down when asked whether his ultimate goal is to oust the Venezuelan president.
Venezuela is a founding member of OPEC and has the largest proven oil reserves in the world. It is exporting about 749,000 barrels per day this year with more than half that oil going to China, according to data from Kpler.
The U.S. has staged a major military build up in the Caribbean. The Trump administration has launched deadly strikes on boats that it says were trafficking drugs to the U.S. The legality of those strikes is disupted and has been subject to scrutiny by Congress.
Trump threatened Monday to expand the strikes to land.
“We’ll be starting the same program on land,” he said. “If they want to come by land, they’re going to end up having a big problem. They’re going to get blown to pieces, because we don’t want our people poisoned.”
Pennsylvania just opened its first federally funded EV charging station on the Pennsylvania Turnpike — a key step toward making long-distance EV travel easier across the state.
The new station just opened at the Blue Mountain Service Plaza at Exit 202 westbound. Another NEVI-funded site at the New Stanton Service Plaza (Exit 77 westbound) is expected to open next week, according to the Pennsylvania Department of Transportation (PennDOT).
The chargers were built using funds from the federal National Electric Vehicle Infrastructure (NEVI) program, which is designed to install fast, reliable charging stations where drivers already stop — especially along busy highway corridors.
The Pennsylvania Turnpike is one of the state’s most heavily traveled roads, particularly during holiday travel, making service plazas a natural location for en-route EV charging. This first Turnpike site marks the beginning of NEVI-funded charging directly on the state’s toll road.

The Blue Mountain and New Stanton locations are part of the Turnpike’s larger, systemwide EV charging rollout. Working with Applegreen Electric, the Turnpike plans to install 80 new universal EV charging stations across all 17 service plazas by the end of 2027.
In addition to the NEVI-funded sites, the Turnpike has already brought new chargers online at the North Somerset, South Somerset, and Hickory Run service plazas using funding from Pennsylvania’s Driving PA Forward program. Each location offers high-speed charging with four ports per site, and all chargers are designed to work with all EV models without the need for adapters.
The project was awarded under the first round of PennDOT’s NEVI Alternative Fuel Corridor program. The next phase of funding, known as Corridor Connections, is focused on filling in charging gaps along major roadways that fall outside previously designated alternative fuel corridors. The goal is to make longer EV trips across Pennsylvania easier and more predictable.
The announcement also comes as Pennsylvania continues to push back against federal attempts to block EV funding. The US Department of Transportation is currently withholding congressionally approved money that would have supported EV infrastructure projects and jobs in the state. Governor Josh Shapiro (D-PA) sued the Trump administration over the move and, alongside 15 other states, successfully challenged an earlier attempt to derail the NEVI program. That legal fight helped keep projects like these Turnpike charging stations moving forward across the Commonwealth.
Electrek’s Take
This is precisely what the Biden administration’s NEVI program was meant to do: put fast, reliable charging stations where drivers already stop. Service plazas on major turnpikes are prime real estate for EV charging, particularly during holiday and long-distance travel. Pennsylvania’s rollout is still early days, but once chargers are live at all 17 plazas – assuming the federal funding spigot stays open – one of the Northeast’s busiest corridors is going to be a great place to road-trip in an EV.
