Rheinmetall presents solutions in South Africa for producing, storing and transporting green hydrogen

Green Car Congress

At this year’s Africa Aerospace & Defence (AAD) expo at AFB Waterkloof in Centurion, Rheinmetall AG is presenting turnkey, mobile modular solutions for producing, storing and transporting CO 2 -free hydrogen. The concept is based on electrolysis; electricity necessary for this is produced with solar panels.

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

Green Car Congress

Rolls-Royce Power Systems has outlined its road map for climate neutrality: Net Zero@Power Systems. From 2025, these will be used in power generation solutions—from balancing energy for compensating fluctuations in the public grid to continuous power and the provision of emergency power in, for example, hospitals and data centers.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. And EV owners would become entrepreneurs, selling electricity back to the grid. And with the revival of the EV, the V2G concept was reborn.

New Lithium rechargeable semi-solid flow cell offers energy densities an order of magnitude greater than previous flow batteries; possible applications in transportation and grid-scale storage

Green Car Congress

The SSFC could enable new models such as transportation ‘fuels’ tuned for power versus range, or cold versus warm climates, with flexible refueling and recycling options. Redox flow batteries have such a design, in which active materials are stored within external reservoirs and pumped into an ion-exchange/electron-extraction power stack.

What is Home energy management system, why it is needed

Baua Electric

These devices offer features that go beyond the capabilities of traditional thermostats, allowing users to have greater control over their home’s climate and energy consumption. Renewable energy integration involves the incorporation of renewable energy sources into existing energy systems, such as electrical grids or heating systems.
