Toyota has opted to postpone the introduction of its 2027 Highlander EV, a move that signals a reevaluation of its electric vehicle strategy. The decision is attributed to the need for further vehicle refinements and, notably, the enduring popularity of its existing gasoline and hybrid Highlander models. This unexpected delay underscores the complexities and fluctuating consumer demand within the automotive industry's transition towards electrification.

Earlier this year, Toyota demonstrated a robust commitment to electric vehicles, rolling out several new or refreshed models in the United States, including the updated bZ series and the new C-HR. Its luxury division, Lexus, also introduced a new electric model, the ES, with another scheduled for release later in the year. The electric Highlander was poised to be a significant addition, marking Toyota's most assertive push into the EV sector after facing criticism for lagging in electrification efforts.

The fifth-generation Highlander was initially planned to debut as an all-electric model by the end of this year, completely replacing its internal combustion engine (ICE) and hybrid counterparts. This would have been a landmark move, making it the first Toyota nameplate to transition exclusively to an EV. The current fourth-generation Highlander, on sale since 2019, is showing its age, and an EV-only successor was seen as a bold step forward. For customers still preferring conventional powertrains, the larger Grand Highlander remains an option. Furthermore, plans were in motion for electric variants from Subaru and Lexus, known as the Getaway and TZ, respectively, based on the Highlander EV platform.

However, the EV market in the U.S. has experienced a shift this year. Factors such as the expiration of federal tax credits and a rollback of fuel economy standards have lessened the urgency for automakers to heavily promote EVs. Consequently, there's been a noticeable acceleration in the adoption of hybrid vehicles over purely electric models. Despite the planned discontinuation of the ICE Highlander, its sales have seen a 6.7% increase year-to-date, with over 32,000 units sold in the first half of the year. The forthcoming Highlander EV promises advanced features like up to 320 miles of range, 338 horsepower, and bidirectional charging capabilities, and is set to be Toyota's first U.S.-manufactured EV, with production planned at its Kentucky plant using North Carolina-assembled batteries. For the interim, the 2026 Highlander will continue production throughout the year and is expected to be available at dealerships well into the next year.

This delay illustrates the cautious approach some manufacturers are taking in the rapidly evolving automotive landscape. While committed to an electric future, Toyota is strategically adapting its rollout schedule, ensuring its offerings align with market demands and are fully optimized before reaching consumers. The strong performance of its traditional models provides a buffer, allowing for careful consideration and refinement of its electric alternatives.

China Three Gorges Corporation (CTG) has inaugurated the world's largest integrated solar photovoltaic and concentrated solar power (CSP) facility in the remote Gobi Desert. This groundbreaking project distinguishes itself by delivering electricity after sundown through a molten salt energy storage system, rather than conventional lithium-ion batteries. The Hami complex in Xinjiang represents a significant leap in renewable energy technology, offering a solution to the intermittency of solar power.

The Hami project, a 1-gigawatt behemoth, combines 900 megawatts of standard solar panels with a 100-megawatt concentrated solar power unit. Spanning 1,817 hectares at the foot of the Tianshan mountains, this facility involved an investment of approximately $480 million. During daylight hours, the vast array of PV panels supplies the grid with electricity. Simultaneously, the CSP unit employs 260,000 tracking mirrors, covering 800,000 square meters, to focus sunlight and heat molten salt to an impressive 550°C. This captured thermal energy is then stored, ready to be converted into steam to drive a turbine once the sun sets, providing power for up to eight hours.

It is crucial to note that the post-sunset power output, lasting for up to eight hours, originates specifically from the 100 MW CSP component, not the entire gigawatt capacity. This demonstrates a dispatchable evening block of power, tackling solar's primary challenge of nighttime generation. The plant's reliance on thermal storage, as opposed to batteries, highlights an alternative strategy for energy resilience. CTG has implemented a linear Fresnel design for the CSP section, which reportedly enhances heat-conversion efficiency by up to 10% compared to traditional Fresnel systems. Additionally, a 46-loop layout ensures continuous operation even during maintenance periods. A sophisticated centralized control system manages the output between the PV and thermal sections, maintaining precise frequency regulation and rapid response times.

While the project officially commenced commercial trial operations on July 1, its connection to the grid dates back to September 18, 2025. Since then, it has maintained a continuous load, feeding 6.54 million kWh into the regional grid. At its maximum capacity, CTG anticipates the complex will generate 2.07 TWh of electricity annually, sufficient to power roughly 830,000 homes. This output is also projected to reduce carbon dioxide emissions by approximately 1.63 million tons each year and boost Xinjiang's renewable energy utilization rates beyond 95%. This achievement surpasses the 950 MW Noor Energy 1 plant in Dubai, making Hami the world's largest CSP-PV hybrid facility.

The debate between molten salt thermal storage and lithium-ion batteries centers on their respective applications. Niu Jianle, project director for the CTG Hami project, emphasizes that lithium batteries are primarily suited for short-duration peak shaving, while CSP thermal storage excels in large capacity, extended discharge cycles, and zero operational emissions. He views the grid connection as a monumental step, transitioning the technology from laboratory research to extensive commercial implementation. The main hurdle for CSP technology has traditionally been its cost-effectiveness compared to PV-plus-battery systems, especially as lithium battery prices continue to decline. The true measure of Hami's success will be its ability to provide affordable power for an extended duration over many years, outperforming the rapidly evolving battery market.

China is heavily invested in this technology, with CTG planning to expand the Hami facility to 3 GW in a subsequent phase. Furthermore, China Energy Engineering Corp has initiated construction on a neighboring 1.5 GW hybrid project, comprising 1.3 GW of PV and 150 MW of CSP, which is poised to surpass Hami's capacity upon completion. This aggressive development underscores China's commitment to industrializing molten-salt storage at a utility scale, a strategy that many other nations have largely overlooked in favor of battery solutions. While CSP's levelized cost has historically lagged behind PV-plus-lithium, the continued innovation and large-scale deployment in China present an intriguing case study for the future of renewable energy storage. The Hami project, despite some skepticism regarding its overall contribution compared to its battery counterparts, undeniably represents a significant engineering feat and a valuable exploration into diverse energy storage solutions.
