Solar and Battery Companies Rattle Utility Powerhouses

Cars That Think

Tesla and its partner Octopus Energy Germany recently rolled out retail utility services in two large German states. The German initiative comes on the heels of a similar rollout through Octopus Energy last November in the United Kingdom. Harmony Energy seems pretty pleased. kWh battery wall unit.

ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

With its bi-directional design, the system also supports use of the vehicle’s batteries for energy storage. Doing so would give energy flexibility to a fleet owner’s business, and help better manage on-site generation such as solar power. UPS appreciates the Department of Energy’s support on this effort.

JRC study finds 8 metals for low-carbon energy technologies at risk of shortages; EVs, wind and solar, and lighting the applications of most concern

Green Car Congress

The applications, i.e. technologies, of particular concern as a result are electric vehicles, wind and solar energy, and lighting. The EU demand for lithium is projected at nearly 15% of the global supply, while that of graphite at 10%. Similar studies could be undertaken for other sectors such as defense and aerospace.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al.

UC Davis researchers suggest we may be at the beginning of a real hydrogen transition in transportation

Green Car Congress

Global public support now totals about $1 billion per year, leveraging many times that amount in private funds. Low-cost shale gas has improved the prospects for natural gas-derived hydrogen, especially in the United States, where it is a major force in the resurgence of federal interest in hydrogen energy. Transition issues.

Roev’s electric ute plans explained: Conversions now, manufacturing its own vehicle by 2026

EV Central

The company is intending to create a so-called micro factory (possibly more than one) that would require much smaller capital investments to open the doors and be profitable churning out as few as 10,000 vehicles annually (most factories need to manufacture hundreds of thousands to be competitive globally).
