Japan plans to fast-track talks with South Africa on a yen-denominated energy loan, while promoting its technology to blend ammonia with coal to reduce carbon emissions in a country that still generates most of its electricity from one of the dirtiest fossil fuels.The loan would be used by South Africa to extend its own energy transition aims, Japanese diplomatic officials said, asking not to be identified in line with government practice, during a visit by Foreign Minister Toshimitsu Motegi. The size of the loan was not specified.Japan’s offer of energy transition assistance for South Africa adds to about $10 billion in climate finance pledged to the continent’s biggest economy by European nations in a formal pact. Countries such as Germany and Japan are seeking to boost the presence of their companies in the nation, which has some of the world’s best solar power and green hydrogen production potential.
