PEM Fuel Cells

Proton exchange membrane Fuel Cells are electrochemical energy conversion devices that utilize hydrogen and oxygen to generate electricity, with the only byproducts being heat and water. PEMFC's operate at relatively low temperatures and can quickly vary their output to meet shifting power demands. Typical applications are automobiles and stationary power production.
Flow Batteries

Flow Batteries are an excellent source for long term and large-scale energy storage due to the high cycling capabilities with minimal performance degradation. Typical applications for Flow Batteries are grid balancing, mini grids, energy storage for renewable energy production, telecom towers and shipping ports.
