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. The Brayton cycle is named after 19 th century engineer George Brayton, who developed this method of using hot, pressurized fluid to spin a turbine, much like a jet engine.

Porsche demos grid balancing capability of group of Taycan EVs with cloud-based pooling system

Green Car Congress

A realistic pilot test conducted by Porsche, the grid operator TransnetBW and consulting firm Intelligent Energy System Services (IE2S), has demonstrated that electrical balancing power can be stored in the high-voltage batteries of an intelligent swarm of electric cars. —Dr Rainer Pflaum, CFO TransnetBW.

Rolls-Royce Power Systems road map for climate-neutrality; 35% cut by 2030 from 2019; key role of mtu engines

Green Car Congress

A key element in achieving these goals is the certification of the most important mtu engine products, which will run on sustainable fuels from as early as 2023 and then be successively brought into use. The aim is to reach a CO 2 net-zero operation of combustion engines. This is not yet relevant for Rolls-Royce applications.

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.

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

The major driver for the project is the need to decarbonize the electrical grid, protect it from cybersecurity attacks and make it more resilient. We will be replicating the entire California power grid on one campus. The goal is to make the testbed available to outside research teams and industry by 2025.

What V2G Tells Us About EVs and the Grid

Cars That Think

As the number of electric vehicles on the world’s roads explodes, electric utilities are grappling with increasing demand while simultaneously having to stabilize their grids where more intermittent renewable-energy sources like wind and solar are coming online. That’s the promise of vehicle-to-grid (V2G) technology.
