The Use of Hydrogen as an Energy Storage System

Many countries around the world have been diligently working towards implementing renewable energy plants for over a decade. According to the International Energy Agency (IEA), renewables in the form of hydropower, bioenergy, wind and solar will account for 18% of primary energy by 2035. Since 2013, more electrical grid capacity was added...

Stationary Fuel Cell Power Applications

Fuel cells can be used for primary power, backup power, or combined heat and power (CHP) for stationary applications. Stationary fuel cells can be sized to power anything from a single-family home to a large business center, which means they make sense for a wide range of markets including retail, data centers, residential, telecommunications, and...

Chemical Hydrides

Fuel cells often use compressed hydrogen as the fuel; however, many other hydrogen sources can be used with fuel cells. Chemical hydride storage is an alternative method of producing hydrogen via a chemical reaction. These reactions involve chemical hydrides, water, and alcohols. The chemical reactions are not reversible, and the byproducts must be discarded. Hydrogen fuel can also...

Carbon Nanotubes

There are many novel hydrogen methods that are currently being investigated that offer the potential for higher energy density than conventional methods. These include hydrogen storage in carbon nanotubes. Carbon nanotubes are unique structures with exceptional electronic and...

Electrical Subsystem of Fuel Cells

If you took the electrical output directly from a fuel cell, it would be an unideal power source. The output of a fuel cell is a DC voltage that varies widely and has a limited overload capacity. The electrical output is slow to respond to load changes because it is based on a chemical reaction, and may have...
