High-density energy storage systems are storage technologies designed to pack more usable energy into less space or weight. Here is what that means in practice, where these systems are used, and the trade-offs that matter most.
Graphene Manufacturing Group has signed a multi-network media deal to promote its graphene production platform and energy-efficiency products, including thermal-management applications aimed at HVAC and data centers.
Battery storage has moved from a supporting role to a central grid technology, with the International Energy Agency saying it was the fastest-growing power-sector technology in 2025 and Reuters reporting a rapid industrial pivot toward stationary storage for data centers.
Meta has agreed to reserve up to 1 GW and 100 GWh of Noon Energy’s ultra-long-duration energy storage, beginning with a 25 MW/2.5 GWh project scheduled for completion by 2028. The deal gives one of the clearest signals yet that data-center developers are looking beyond conventional batteries for multi-day firm power.
Coherent has introduced Thermadite 800 liquid cold plates for AI accelerator cooling, a move that brings an ultra-thermally conductive material into the fight against rising chip heat in high-density data centers.
Graphene Manufacturing Group has received U.S. Environmental Protection Agency approval for the import and sale of its THERMAL-XR graphene coating in the United States, clearing a regulatory hurdle that had blocked commercial sales in the country. The decision gives GMG and distributor Nu-Calgon the right to begin shipments into the HVAC-R market, with applications also cited for data centers, electronics and other industrial uses.
