Principles and Applications of Hydrogen Energy Technology

Flashcards covering key vocabulary related to hydrogen energy technology.

Hydrogen Energy

A clean, efficient alternative to fossil fuels that produces only water vapor as a by-product.

Electrolysis

A process that uses electricity to split water into hydrogen and oxygen.

Fuel Cells

Devices that convert hydrogen into electricity through electrochemical reactions.

Green Hydrogen

Hydrogen produced using renewable energy sources via electrolysis.

Hindenburg Disaster

A tragic event in 1937 where a hydrogen-filled airship caught fire, raising safety concerns about hydrogen.

Thermochemical Process

A method of splitting water or methane with high heat to produce hydrogen.

Hydrogen Storage

The methods used to store hydrogen safely, which can include compression or liquefaction.

Proton Exchange Membrane (PEM)

A type of electrolyzer that produces hydrogen from water without corrosive chemicals.

Hydrogen Fuel Cell Efficiency

Approximately 60% efficiency at converting stored energy compared to 30% in internal combustion engines.

Blue Hydrogen

Hydrogen produced from natural gas with carbon capture and storage.

Hydrogen Applications

Uses of hydrogen across various sectors, including transport, electricity generation, and industrial processes.

Greenhouse Gas Emissions

Gases that trap heat in the atmosphere, which hydrogen energy aims to reduce.

Hydrogen Safety,

Considerations for safely using and storing hydrogen due to its flammability and volatility.

Fuel Flexibility

The ability of hydrogen technologies to work with various fuel sources and applications.

Disadvantages of Hydrogen Energy

Challenges such as high costs, storage difficulties, and lack of infrastructure.
