A Massachusetts-based battery startup, Alsym Green, has developed a new battery pack that is being hailed as a game-changer for the energy storage sector. The Malden-based company’s product is a solution for grid, home, business, and data center storage, and is said to be fire-safe and sustainable. What sets it apart from other battery packs is its use of common water in its chemistry, making it a safer and more environmentally friendly option.
The need for reliable energy storage has become increasingly important with the rise of renewable energy sources like wind and solar. While lithium-ion packs, such as Tesla’s Megapack, have been the go-to solution for energy storage, they come with their own set of risks, including fire hazards and reliance on foreign and expensive supply chains. Alsym Green aims to address these issues with its innovative battery pack.
The battery works similarly to a lithium-ion pack, with ions moving between two electrodes through an electrolyte. However, Alsym Green replaces toxic and flammable materials with water and nonhazardous additives, making it less prone to thermal runaway and fire. This also means that the materials used in the battery are all available in the US or from reliable trade partners, reducing pricing and supply volatility.
In addition to being a safer and more sustainable option, Alsym Green also offers long-duration energy storage capabilities. The battery can discharge for up to 110 hours and recharge in less than four hours, giving customers the flexibility to manage their energy demand and take advantage of electricity market opportunities. It also provides up to five days of power for blackout protection, which is becoming increasingly important as severe weather events linked to climate change can cause mass outages.
While Alsym Green’s battery packs are still in the early stages of development, they have the potential to revolutionize the energy storage industry. By addressing key issues such as safety, sustainability, and reliability, Alsym Green is taking on one of the world’s greatest challenges and paving the way for a cleaner and more resilient energy future.
