Air Products’ Hydrogen Energy Station produces renewable electricity, hydrogen and heat from biogas.
Hydrogen is being considered as a replacement for today's fossil fuels because it is abundant, efficient, and unlike other alternatives, it offers the potential to be renewable and it produces no emissions. It can be utilized as the energy carrier for generating electrical power with hydrogen fuel cells and hydrogen combustion engines.
Within a hydrogen fuel cell, hydrogen combines with oxygen from the air to create electricity. The fuel cell can run continuously and generate energy as long as the hydrogen fuel is being supplied, and the only by-products are heat and water.
Many fuel cells utilized today for distributed power generation require integration with a fuel processor to produce a hydrogen-rich gas from a hydrocarbon based fuel such as natural gas or propane. However, numerous benefits can be realized by the use of direct high purity hydrogen to the fuel cell. The applications that are amenable for direct hydrogen fuel sourcing include portable devices, primary power, backup power, peak-shaving and grid stabilization.
