Hydrogen Could Help Halve Global Carbon Emissions By 2050

Aggressively expanding the use of hydrogen and other cleaner energies could halve emissions of carbon dioxide (CO2), the main greenhouse gas, by 2050, the International Energy Agency (IEA) said here Thursday. In a report coinciding with a key UN conference on global warming, the IEA said that if conditions were right, hydrogen and hydrogen fuel cells could play key roles in weaning energy users away from oil, gas and coal.

“In the most favourable conditions, hydrogen fuel cell vehicles would enter the market (in mass numbers) around 2025 and power 30 percent of the global stock of vehicles by 2050 — the equivalent of about 700 million vehicles,” the IEA said. “The oil saving would then be equivalent to some 13 percent of global oil demand, or five percent of the global energy demand.”
