Rolls-Royce mtu Kinetic PowerPack approved for renewable diesel

Green Car Congress

Rolls-Royce has approved its mtu Kinetic PowerPacks, based on the mtu Series 4000 and 1600 diesel engines, for use with renewable diesel (HVO/Hydrogenated Vegetable Oil) and the other synthetic diesel fuels of the EN15940 standard. The systems performed the same with HVO as with fossil diesel.

OptiFuel to repower Argentina’s 400 freight locomotive fleet from diesel-power to CNG and/or RNG

Green Car Congress

Traditional locomotives run on diesel fuel, emitting high levels of NO x , PM, and CO 2. OptiFuel is developing modular repower kits for diesel locomotives and new locomotives in all lengths, horsepower levels, and track gauges. For line-haul operations in the US, RNG is the only practical zero-emission diesel-alternative solution.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. It took us a long time to get the data needed to let us connect to the grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%.

Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

With battery storage able to provide a unique role in balancing a renewable electricity grid, Toby Gill, CEO of Intelligent Power Generation, asks could innovations in green hydrogen and biofuel technologies contribute to a more optimized and economical energy mix? Our grid is changing, and so must the way we operate it.

Siemens Energy, FFI and GeoPura developing prototype ammonia cracker to produce hydrogen

Green Car Congress

We have just 13 years to deliver a net-zero electricity grid for the UK. It can be used for storing large amounts of hydrogen in a liquid form that builds on existing global supply chain infrastructure. The technology could then be scaled up for future markets, including industry, heat, and grid-scale power generation.

GM expanding into new commercial applications for its HYDROTEC fuel cell systems

Green Car Congress

These fuel cell generators could ultimately replace gas- and diesel-burning generators with fewer emissions at worksites, buildings, movie sets, data centers, outdoor concerts and festivals. They could also back up or temporarily replace grid-sourced electricity for residential and small commercial enterprises at times of power disruption.
