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

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Cell schematic. Discharge mode is shown; the arrows are reversed for electrolytic/charge mode.

European HEFT project seeks lower-cost, more efficient and power-dense PM emotor for EVs

Green Car Congress

The innovations are intended to result in a high-efficient and low-cost solution that will be validated on 2 motor topologies, which will be compared to two main reference automotive IPM commercial motors in Europe (VW ID.3

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Abatement cost with hydrogen at $1/kg (7.4/MMBtu).

Cornell team develops new inexpensive stereo-camera method to detect objects for self-driving cars; pseudo-LiDAR

Green Car Congress

These sensors are affixed to cars’ roofs, where they increase wind drag, a particular disadvantage for electric cars. They can add around $10,000 to a car’s cost. They refer to this representation as pseudo-LiDAR, and process it exactly like LiDAR—any LiDAR-based 3D objection algorithms thus can be applied.

Georgia Tech study suggests unlinking EVs from CAFE and coordinating with power sector for low-cost benefits

Green Car Congress

A negative value means the case has a lower TCE than the reference case. The controlled charging of EVs can reduce electricity costs and improve the integration of wind energy. The benefit per average vehicle is small at low to moderate EV adoption levels because EVs are a small fraction of the fleet. Click to enlarge.
