Japanese trading house Mitsui & Co. announced an investment in U.S.-based synthetic fuel maker Twelve Benefit Corp, along with partners like Mitsui O.S.K. Lines Ltd. and the Development Bank of Japan. Synthetic fuels, derived from carbon dioxide and hydrogen generated through renewable energy sources like solar power, offer a more environmentally friendly alternative to traditional fossil fuels. The demand for synthetic fuels, particularly for sustainable aviation use, is expected to rise due to their substantial CO2 emission reduction benefits.
