As fossil fuel usage increases, greenhouse gas emissions, including carbon dioxide, are getting worse. This changes the climate and has brought serious impact on the systems of nature and human society across all continents and oceans. Climate change has countless negative consequences, including rising sea levels, flooding and storm tidal waves, drought, and loss of marine and land ecosystems. For this reason, The world agrees on the need to reduce greenhouse gas emissions and is working toward a reduction target.

Humans can endure for a certain period of time without drinking food or water, but if human don't breathe air, human can't live for even five minutes. Such important air has a serious impact not only on the ecosystem, the greenhouse effect, increased acid concentration, but also destroy ozone, dust, nitrogen oxide, sulfur oxide from various industries resulting in changes in oxygen concentration in the atmosphere. Hydrogen is a clean energy source with only water emissions and contributes to reducing air pollution.

Energy independence is the concept of self-producing and consuming the necessary energy. In particular, Korea relies on imports for 97% of its energy needs, which is an urgent task because it is vulnerable to problems such as geopolitical bias in energy producers, competition for energy sources, and infrastructure destruction caused by natural disasters. Hydrogen, one of the eco-friendly energy sources, is seen as a solution that will reduce energy dependence on other countries and contribute to energy independence.

As the world's population grows, more and more people have an energy-intensive lifestyle. Therefore, the need to supply more energy has emerged, and hydrogen can meet the growing energy demand with high-efficiency energy with political power generation efficiency of 35%~60% for fuel cells and 80% of total energy efficiency combined with electricity and heat. It is spotlighted as a new energy source.

Current energy systems are vulnerable to accidents and disasters, as they are mostly concentrated in large power plants. A stationary fuel cell using hydrogen and a fuel cell vehicle capable of supplying power in an emergency are distributed energy and play an important role in the recovery elasticity in an emergency.

The development of new technologies contributes to job creation, driving economic growth. Hydrogen is an eco-friendly energy that has a great economic ripple effect, which can cause chain reactions to industries such as petrochemicals, steelmaking, construction, automobiles, materials, and parts, and give a great boost to investment and job creation.
