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

Green Car Congress

In a paper in Nature , they suggest that the use of such redox-active organic molecules instead of redox-active metals represents a new and promising direction for realizing massive electrical energy storage at greatly reduced cost. Thus the amount of energy that can be stored is limited only by the size of the tanks.

Siemens presents three-point plan for implementing cost-efficient energy transition in Germany

Green Car Congress

Relying on a higher share of efficient, low-emission combined cycle power plants and wind energy could save €150 billion (US$200 billion) by 2030 while attaining the same CO 2 targets, Siemens says. However, the financial cost of the shift is causing concern. Electricity prices in comparison. Source: Siemens. Click to enlarge.

EU investing €1.8B in 17 large-scale clean tech projects

Green Car Congress

The 17 projects were selected under the second call for large-scale projects, meaning they have capital costs above €7.5 Other selection criteria included the projects’ potential for scalability and cost effectiveness. Another project in Sweden will produce a new fiber from pulp to substitute polyester in textile applications.

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 SET Plan was launched in 2008 with the objective to accelerate the development and deployment of cost-effective low carbon technologies.

Two studies exploring battery costs for hybrids and plug-ins: LEESS, PHEV20, and PHEV40

Green Car Congress

For PHEV20 batteries, TIAX found significant overlap in battery costs among five cathode classes, with wider variation within each chemistry based on the electrode design than between chemistries. Costs were modeled for a 300V PHEV battery pack that could provide 5.5 Systems costs ranged from about 250 – 700 $/kWh.

UniEnergy signs commercialization agreement for PNNL-developed vanadium redox flow battery

Green Car Congress

First developed in the 1970s, redox flow batteries are one type of storage technology that has shown the ability to meet the challenge of integrating energy from variable and intermittent sources such as wind and solar power onto the electricity grid while maintaining grid stability.
