Power outages can cripple businesses and back-up generators are often diesel fuelled, expensive, noisy and dirty. Enter the 220- 250kw fuel-flexible "linear generator". Mainspring's generators can run on natural gas, propane, biogas or hydrogen, and are designed to ramp up and down to fill gaps in power supplies, either on their own or as part of a microgrid with renewable energy & battery storage. The simple (compression) design, with no flame/spark or spinning elements, also means it should be lower cost, lower maintenance and lower emissions to other traditional generators.https://www.mainspringenergy.com/
German companies and researchers, led by MAN Energy Solutions, are working on a medium speed engine that can burn both diesel and ammonia. Ammonia is made from hydrogen through the Haber-Bosch at industrial scale and is a better energy carrier than hydrogen due to its high stability and energy density. An ammonia engine makes it possible to direct use of ammonia as power fuels by the transport sector for higher energy efficiency without converting it back to hydrogen. https://www.offshore-energy.biz/man-energy-kicks-off-ammoniamot-project/
