Toshiba's hydrogen business

  • To achieve carbon neutralitv
  • 1967 History of Toshiba's hydrogen energy systems
  • 1978 Toshiba is first in Japan to generate electricity with fuel cells at a 50-kW phosphoric acid fuel cell demonstration power generation plant
  • 1991 Delivery of demonstration equipment to the then world's highest-capacity 11-MW fuel cell power generation plant using phosphoric acid fuel cells (located in the Goi Thermal Power Station of TEPCO)
  • 2005 Participation in the demonstration project for the world's largest green energy recycling system using 200-kW fuel cells (Aichi Expo)
  • 2013 H2Rex™ series of pure hydrogen fuel cell systems suitable for a wide range of commercial and industrial applications
  • 2014 Launch of H2One™, an autonomous hydrogen energy supply system that provides a comprehensive solution for the production, storage, and use of hydrogen

The reduction of CO2 emissions is needed to curb global warming. Hydrogen energy has been attracting a lot of attention since hydrogen power generation does not emit CO2. As a leading energy company, Toshiba will realise green energy supply by using hydrogen technology, which is one of the energies that Toshiba has cultivated as a leading company.

Initiatives for carbon neutrality

For a sustainable society, there are various issues to be solved, such as global warming and abnormal weather. Now, Japan and other countries around the world are aiming for "carbon neutrality". This is to curb greenhouse gas emissions and curb temperature rise. More than 90% of greenhouse gases are carbon dioxide in Japan.

①Reduce carbon dioxide emissions


●Use of renewable energy

Most of the carbon dioxide currently emitted comes from energy. To reduce this emission, the conversion to renewable energy with low carbon dioxide emissions is underway, and the national target is to raise the ratio of renewable energy to 50-60% by 2050.

However, the output of renewable energy tends to fluctuate due to the influence of the weather, so adjustment technology is required to secure stable power.


●The role of hydrogen

Hydrogen is considered to be a carbon-neutral key technology. Only water, not carbon dioxide, is generated during power generation. By storing the surplus of renewable energy as hydrogen, it can be used at different times and places. It becomes possible to:
 ● Use it as power for adjustment power
 ● Use it outside the power sector
Hydrogen makes effective use of renewable energy and contributes to carbon neutralization.

Toshiba's hydrogen energy related business

Sustainable society contributed by Toshiba technology

① Hydrogen energy that does not emit carbon dioxide


Toshiba contributes to the reduction of carbon dioxide emissions through the technology of "Produce・Store・Use" Hydrogen.

Produce・Store・Use Hydrogen

② Effective use of carbon dioxide


There are areas where it is difficult to control carbon dioxide emissions, as part of the hot heat utilization and industrial process sector. Toshiba has developed and emitted a technology to separate and recover the emitted carbon dioxide and a new technology that decomposes carbon dioxide into carbon monoxide and can convert it into chemicals and fuel. We are also working on the recycling of carbon dioxide.

History of Toshiba's hydrogen energy systems

Toshiba commenced the development of fuel cell systems in the 1960s. Since then, Toshiba has continually developed hydrogen-related technologies.
