Mitsubishi Heavy Industries Ltd (MHI) announced Feb 27, 2019, that it has selected four environment-related cases such as a rooftop solar power generation (PV) system set up at a manufacturing plant in Thailand for the "Best Innovation 2018."

The Best Innovation 2018 is a corporate commendation system for improving environmental consciousness and encouraging further technological innovations in the group.

For the "Environment/Practice Award," which commends activities that contributed to global environmental protection, MHI selected a rooftop PV system that the Thai Plant of Mitsubishi Turbocharger Asia Co Ltd (MTA) installed in March 2018. The capacity of the system is 3.95MW, and it generates 5.8GWh of electricity per year. The system uses facilities manufactured by Kyocera Corp. Electricity generated with the system is consumed in the plant (e.g. air-conditioning system).

It is the MHI group's largest-scale rooftop PV system and one of the largest-scale rooftop PV systems in the ASEAN region. The PV system received an award from the Thai government because "it eliminated nearly 3,000t of CO2 emissions per year and contributed to the reduction of greenhouse gas."

For the "Environmental Product Award," which is for products contributing to global environmental protection, MHI selected (1) a freezing/refrigerating unit that uses CO2 (natural refrigerant) in place of chlorofluorocarbon (CFC) or alternative CFC, (2) gas purification device that is for ships and supports the regulations on the emissions of SOx (sulfur oxides) from ships, which will become stricter in 2020, and (3) the Azalea/Lavender New Japan Sea Ferry, which emits about 30% less CO2 (ton per mile), compared with the global average.

The Best Innovation is a commendation system targeted at creative new technologies/services, new technologies, new businesses, etc of the MHI group. It has annually been used since fiscal 2003. This time, a total of 16 cases received awards including the four environment-related cases.

MHI deals with geothermal power plants and, through a joint venture formed with Vestas Wind Systems A/S, large-scale offshore wind power generation facilities and has a good track record on a global basis. Also, the company developed and sold amorphous silicon thin-film solar panels in the past.
