Toward the achievement of a carbon neutral society, the adoption of new energy sources such as hydrogen is progressing worldwide, in addition to further improvement in the efficiency of energy use. However, the industry faces many challenges in its practical application, such as reducing production costs. Moreover, technological development for CO2 capture and reuse is also advancing, yet there remain many hurdles that must be overcome. 

We believe that it is important to operate each energy source in an optimal manner with high efficiency, low emissions, and minimal energy loss, and we are committed to working together with key players in the industry to realize a new era of "generating," "storing," and "using" energy in a smart way, from the aspects of analysis and measurement. We will continue to make concerted efforts to realize a new era of "generate," "store," and "use" energy wisely.
