Reason why hydrogen is necessary
I have talked about DENSO’s vision of carbon neutrality.Now, let me talked about why hydrogen is necessary. I mentioned earlier that we are developing batteries and CO2 capture technology as well. though.
The pie chart on the left shows annual greenhouse gas emission volume. The leftmost blue segment represents the CO2 emissions from thermal power plants. The segments enclosed by the red line represent the CO2 emissions from customers, including households and enterprises. The sources of CO2 emissions are fossil fuels, such as gasoline and city gas.
To achieve carbon neutral, fossil fuels used by power plants and customers must be replaced by electricity and hydrogen. In general, hydrogen is known to be used in fuel cells for power generation, but it can be used for various applications.
Hydrogen is used as a fuel to power vehicles such as fuel cell vehicles (FCVs) and to generate power in fuel cells. In industry, hydrogen is used as a fuel for boilers and furnaces to generate heat. In fact, hydrogen is already used for various applications, in which it is typically sourced from coal and natural gas, which are fossil fuels. Significant progress toward decarbonization can be made by replacing the hydrogen with clean hydrogen derived from renewable energy. Thus, hydrogen is essential for decarbonizing the fields in which customers operate.
As I explained using this pie chart, thermal power plants account for 40%. Decarbonization is done by combusting hydrogen and ammonia. Accordingly, hydrogen is indispensable for society.
