A 3.8MW solar carport, one of the largest among domestic universities, begins operation at the University of Miyazaki Promoting a zero-carbon campus by reducing CO₂ emissions by approximately 1,400 tons per year

The University of Miyazaki has set a goal of reducing the total greenhouse gas emissions directly or indirectly associated with university administration and business by 51% by 2030 (compared to 2013), Our basic philosophy is to aim for the realization of ``neutral.''
To achieve this goal, Idemitsu Kosan and Solar Frontier installed solar carports on campus. By signing a PPA (power purchase agreement) with Idemitsu Kosan, the University of Miyazaki will be able to introduce and operate a solar carport that utilizes the know-how of Idemitsu Kosan and Solar Frontier without incurring initial investment or maintenance costs. can.
The newly introduced solar power generation will supply approximately 23% of the electricity used at the Kibana campus, approximately 16% of the electricity used at the Kiyotake campus, and approximately 18% for the university as a whole. As a result, the University of Miyazaki is expected to be able to reduce CO₂ emissions by approximately 1,400 tons per year, or approximately 12% of the university's overall emissions. In addition, it will be possible to procure electricity at a lower price than the most recent unit price of electricity, which is expected to reduce electricity costs.
This solar carport uses a double-sided photovoltaic module, which generates power not only from sunlight but also from the light reflected from the ground, ensuring a larger amount of power than a typical solar cell module. can. It also has a power storage system that can charge EVs, so it can also be used as an emergency power source.
In addition, synthetic calcium carbonate (Calcarbo®), which is produced from CO₂ in exhaust gas using Idemitsu Kosan's carbonation technology, is used as a paving material in some of the paved areas on the grounds of the University of Miyazaki Konohana campus. Approximately 110 kg of CO₂ is fixed.

At the University of Miyazaki, we aim to become carbon neutral in 2050, and are promoting various initiatives including energy saving and energy creation, and are promoting a lot of research related to renewable energy such as solar power generation, fuel cells, and biomass. I'm here. Regarding solar power generation in particular, we have installed solar power generation systems from almost all domestic manufacturers on campus and are conducting joint research with companies, including analysis of power generation performance.

This initiative is positioned as an effort toward the development and provide for society of "Energy one step ahead" among 3 business domains mentioned above. Idemitsu Kosan and Solar Frontier will continue to promote decarbonization in the region and contribute to the stable supply of carbon-neutral energy.
