Everllence, the German engine manufacturer formerly known as MAN, has successfully run its ethanol-fuelled 21/31 dual-fuel engine at test facilities in Frederikshavn. The company was the first engine manufacturer to launch a small-bore, four-stroke, methanol-burning engine in 2024, known as the 21/31DF-M unit. Several are already in commercial operation. The company continued work on the 21/31 platform and has completed successful operation on ethanol. This provides Everllence with a fully operational engine with which to document ethanol’s capabilities as fuel. “This engine platform has shown great promise when burning alternative fuels, and during testing, we even managed to expand the ethanol fuel share compared with methanol. In general, the past few years have seen steadily growing interest in ethanol from the market,” said Rasmus Frimann Nielsen, senior manager and head of four-stroke small-bore engineering at Everllence. He added that the company was still evaluating the data, and that it confirms earlier assumptions that the company could run the 21/31 engine on ethanol without issues. “Our position as the world’s leading engine designer means that we have a special, ongoing obligation to develop new technologies to decarbonise the global maritime industry. Now we need legislation in place that considers the case of ethanol as a viable fuel source, as well as developing a requisite market demand,” added Lars Zimmermann, director of sales and promotion for marine GenSets at Everllence. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1_95_0_1_2'); }); TagsGermany
