Toshiba provides a one-stop solution for all hydrogen processes, from production to storage and use. We can do this thanks to our technologies for generating power from renewable energy sources and our knack for finding ever more efficient ways to utilize hydrogen--advantages Toshiba has been developing since its establishment as a leading company in the energy industry.

Energy issues in Japan

Japan faces three energy issues. The first is the nation's low rate of self-sufficiency in energy. Although Japan ranks 5th in the world in terms of energy consumption, its energy self-sufficiency is only 6%. This means that among developed countries, Japan's energy supply risk is great. Japan's second issue is its high rate of CO2 emissions. Producing some 1,220 million tons of CO2 per year, Japan ranks 5th in the world. Finally, Japan faces the key issue of finding a way to manage the unstable energy supply from renewable resources such as wind and solar power, across the range of weather conditions.

What can CO2-free hydrogen do?

CO2-free hydrogen is generated from solar power, wind, and water. This frees us from our reliance on imported natural resources. Generating electricity with zero CO2 emissions, it's the ultimate clean energy source. Furthermore, CO2-free hydrogen constitutes a renewable energy source that can be stored in various forms such as gas, liquid, and more--which means it can be stored and transported stably. CO2-free hydrogen also achieves high energy-efficiency because the thermal energy generated through the use of electricity can be utilized for fuel cells or for heating.
