Following its successful concept validation in laboratory settings and at MARIN, where the system demonstrated resilience in harsh ocean conditions, Sizable Energy is now progressing with a new prototype test in the Mediterranean. This pilot project, situated off Reggio Calabria, Italy, is designed to confirm the efficacy of its floating system, assembly processes, and deployment techniques. This critical step is intended to pave the way for a multi-megawatt demonstration plant in the Mediterranean Sea. Looking ahead, the company aims to initiate commercial project development by 2026 across multiple global locations. This expansion will involve collaborations with governments, energy providers, and local manufacturers to scale up long-duration ocean energy storage solutions.

Sizable Energy's innovative approach to energy storage, by transforming ocean depth into a sustainable power reserve, represents a monumental stride towards a more sustainable and resilient global energy landscape. By effectively addressing the intermittency challenges of renewable energy, this technology not only promises economic viability but also underscores humanity's ingenuity in leveraging natural resources responsibly, paving the way for a future powered by clean, stable, and abundant energy.

China's Chery Automobile Pioneers 800-Mile Solid-State EV Battery, But US Access Remains Uncertain

Chery Automobile, a leading Chinese car manufacturer, has announced a significant advancement in electric vehicle technology with the development of a solid-state battery prototype. This innovation promises to dramatically extend EV driving ranges, potentially reaching over 800 miles, while also offering superior safety compared to existing lithium-ion batteries. Despite this breakthrough, new export regulations from China could limit the availability of this technology in markets like North America, highlighting the growing geopolitical factors influencing technological dissemination in the automotive sector.

Chery's Breakthrough in Solid-State Battery Technology

Chinese automotive company Chery has recently revealed a groundbreaking solid-state battery prototype that promises to revolutionize the electric vehicle industry. This new battery technology boasts an impressive energy density of 600 watt-hours per kilogram, which is more than double that of current lithium-ion batteries. Such a leap in energy density could translate to an electric vehicle driving range of up to 1,300 kilometers (approximately 807 miles) under the China Light-Duty Test Cycle (CLTC), effectively addressing range anxiety, a major concern for potential EV buyers. The battery's design incorporates a lithium manganese rich cathode and an innovative 'in-situ polymerized solid-electrolyte,' a material formed within the cell during the manufacturing process, enhancing its performance and safety characteristics.

The company showcased the resilience of its new battery module through rigorous testing, including nail penetration tests, which it reportedly survived without igniting or emitting smoke. This enhanced safety profile is a key advantage of solid-state batteries, which are generally considered less prone to thermal runaway than their liquid electrolyte counterparts.
