Following talks between Kazakhstan's President Kassym-Jomart Tokayev and Abu Dhabi's Crown Prince Sheikh Khalid bin Mohammed bin Zayed Al Nahyan, the two countries signed a series of cooperation agreements. The agreements cover a wide range of areas, including energy, transportation, justice and digitalization, and are aimed at deepening bilateral cooperation.

Bulgarian energy storage manufacturer has released a new utility scale battery energy storage system with a rated capacity of 8.1 MWh and integrated 4 MW inverters. The X-BESS 8 system is installed in a space equivalent to a 20 foot container and uses liquid cooling technology.CEO Alexander Langlov stated, "In terms of capital expenditures, a compact modular architecture enables easy customization and future oriented expansion, while significantly reducing system balancing , transportation,and installation costs. In terms of operating expenses, all key components adopt a distributed design to ensure that the system is easy to maintain and runs reliably throughout its entire lifecycle, avoiding single point of failure for the entire system. ”

Market analyst firm IDTechEx predicts the lithium - sulfur market will exceed $1.3 billion by 2035 and global production will exceed 14 GWh. Lithium - sulfur batteries use a lithium metal negative electrode and a sulfur positive electrode, having high energy density by weight, potential cost - reduction due to abundant sulfur reserves, and improved safety. They're expected to be in mass production by 2033. However, they face issues like polysulfide shuttling, which reduces Coulombic efficiency and battery life, lithium metal dendrite formation, and significant cathode expansion during charge - discharge. To counter polysulfide shuttling, solid electrolytes, alternative liquid electrolytes, or diaphragms can be used. Cathode swelling can be solved by alternative cathode structures or materials like sulfurized polyacrylonitrile. These batteries are suitable for aerospace, defense, maritime applications (especially UAVs) and are expected to be used in electric vehicles, particularly heavy - duty ones.
