1s1 Energy (Accelerator)

Company Description: 1s1 Energy is a Portugal and US-based company developing key technology that improves the economics of water electrolysis to eliminate the 300% to 400% "green premium" that hampers the adoption of green hydrogen. A core element of the technology is a novel proton exchange membrane (PEM) that provides superior performance and durability at a fraction of the cost, enabling a Levelized Cost of Hydrogen production (LCOH) below $1.5/kg. 1s1 Energy will be producing PEMs, water electrolysis stacks, and 1 MW water electrolysis modules. The 1 MW modules will be integrated into 2-10 MW distributed operation or combined to realize centralized plants with a capacity exceeding 100 MW. 1s1 scale-up plan includes working with large plant integrators that use third-party electrolysis stacks and modules to implement hydrogen fueling stations and large plants by first engaging in testing collaborations to develop these products to meet their specifications.
