What are the environmental benefits of hydrogen fuel cells in?.

Hydrogen fuel cells are an innovative technology that generates electricity by combining hydrogen and oxygen, emitting only water vapor as a byproduct. This process significantly reduces harmful emissions compared to internal combustion engines.

Key Facts

• Hydrogen fuel cells produce only water vapor, contributing to cleaner air.
• They operate efficiently, converting about 60% of the energy from hydrogen into power.
• The use of hydrogen can reduce greenhouse gas emissions by up to 90% when sourced from renewables.
• Deployment of hydrogen technology is expected to grow, with projections of over 10 million hydrogen vehicles by 2030.

Examples or Use Cases

• Numerous automotive manufacturers are investing in hydrogen fuel cell technology, including Toyota with its Mirai model.
• Hydrogen fuel cells are also used in public transport systems, such as buses in Germany and Japan, reducing urban pollution.

FAQs

• What is the main byproduct of hydrogen fuel cells? Water vapor is the main byproduct, making them environmentally friendly.
• How does the efficiency of hydrogen fuel cells compare to traditional engines? Hydrogen fuel cells are significantly more efficient than traditional internal combustion engines, which typically convert only about 20% of their fuel energy into usable power.
