Hydrogen Economy Working, Importance, and Future.
                     Hydrogen Economy: Working, 
Importance, and Future
HYDROGEN ECONOMY
• The hydrogen economy is an envisioned 
future in which hydrogen is used as a fuel 
for heat and hydrogen vehicles, for energy 
storage, and for long distance transport of 
energy.

POWER GENERATION 
• Once hydrogen is ready to be consumed, it is 
necessary to do so in the most effective way: the 
power generation system that uses hydrogen 
needs to be both efficient and, for mobile 
application, lightweight.

HYDROGEN PRODUCTION FROM WATER
• Although many technologies have been explored 
for production of hydrogen by splitting water into 
hydrogen and oxygen, these processes have yet 
to achieve the necessary efficiency and scalability 
for industrial application.

BIOHYDROGEN PRODUCTION
• Biological H2 production represents an effort to 
harness biological processes to generate 
hydrogen on the industrial scale. 
• Although they have found no industrial 
application, there are a number of processes for 
conversion of biomass and waste streams into 
biohydrogen.

IMPORTANCE OF HYDROGEN ECONOMY
REDUCES POLLUTION
• When hydrogen is combined with oxygen in a 
fuel cell, energy in the form of electricity is 
produced. 
• This electricity can be used to power vehicles, as 
a heat source and for many other uses. 
• The advantage of using hydrogen as an energy 
carrier is that when it combines with oxygen the 
only byproducts are water and heat.

HYDROGEN CAN BE PRODUCED 
LOCALLY FROM NUMEROUS SOURCES
• Hydrogen can be produced either centrally, and 
then distributed, or onsite where it will be used. 
• Hydrogen gas can be produced from methane, 
gasoline, biomass, coal or water.

SUSTAINABLE PRODUCTION SYSTEM
• Electrolysis is the method of separating water 
into hydrogen and oxygen. 
• Renewable energy can be used to power 
electrolyzes to produce the hydrogen from water. 
• Using renewable energy provides a sustainable 
system that is independent of petroleum 
products and is nonpolluting.

FUTURE OF HYDROGEN 
ECONOMY
• With increasing use of hydrogen and technical 
advances, the costs of production, distribution 
and product manufacturing will becoming 
increasing affordable. 
• By continuing to build partnerships between 
business, government , universities and non-
profit organizations hydrogen will be the 
foundation of a sustainable energy economy.
