Rolls-Royce Tests Hydrogen-Powered MTU Engine

In a major advance for hydrogen power, Rolls-Royce announced last week that it completed testing a hydrogen-powered MTU engine, and it worked. The bench test was on a 12-cylinder MTU Series 4000 gas engine (pictured above) using 100 percent hydrogen fuel. For the test, Rolls-Royce engineers had to modify some MTU components, including fuel injection, turbo-charging and piston design, because of the different combustion of hydrogen, compared to gas. The test lasted several months, but then Rolls-Royce announced it was successful in terms of efficiency, performance and combustion. MTU has been making engines in Germany for more than a century.…
