Bipolar plates are a key component of PEM fuel cells, providing structural support and carrying out a major role in the power generating electrochemical reaction. This article discusses the materials consideration for plates, which can be made from metal or graphite/graphitic composite.

Supercapacitors are energy storage devices that offer distinct properties when compared to batteries. Supercapacitors have higher power density and lower energy density than batteries. They also have a significantly larger cycle lifetime, in the tens of thousands, which enables them to undergo frequent charge-discharge cycles without degradation. This allows them to perform in applications where batteries are not appropriate. IDTechEx covers supercapacitors in detail in its recent report: "Supercapacitors 2026-2036: Technologies, Applications and Forecasts".

The climate crisis demands diversity in decarbonization solutions. From CCUS (carbon capture, utilization, and storage) to renewable electricity from wind and solar power, many green technologies must grow in tandem. In this article, IDTechEx explores how electrochemical technologies could redefine carbon capture as an energy asset.

The transition to 800V EVs is one which affects the whole powertrain, including the power electronics. In IDTechEx's report, Power Electronics for Electric Vehicles 2026-2036: Technologies, Markets, and Forecasts, these trends are analysed and used to forecast the adoption of wide bandgap semiconductors SiC and GaN, as well as the entire power electronics market for electric vehicles (EV).

As the demand for clean green hydrogen grows, electrolyser demand will grow in tandem. This article details which electrolyser components will seize market value based on adoption of different electrolyser technology solutions.

The reliability of high-tech, miniaturized technologies is something easily assumed, but could they be reaching their peak? The looming presence of recent solar flare activity impacting communications is a reminder of the large and ever-present phenomenon of outer space, and could mean preparing for the return of communication-by-pigeon.

Despite a year of critical material supply disruptions, technology mega-trends in decarbonization, electrification, automation and AI continue to fuel demand for high-performance rare earth magnets. IDTechEx forecasts that rare earth magnet demand will reach 332 ktpa by 2036 and breaks down usage and adoption trends in electric vehicles, wind turbines, and robotics growth markets.
