Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation. The apparent contradictions do not end there.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

The KU Leuven bioscience engineers solved this problem by designing a solar panel of 1.6 The hydrogen gas produced in the summer will be stored and converted into electricity and heat in the winter. The hydrogen gas produced in the summer can be stored in an underground pressure vessel until winter. —Johan Martens.

Georgia Tech researchers develop aluminum-foil-based anodes for all-solid-state Li-ion batteries

Green Car Congress

These results demonstrate the possibility of improved all-solid-state batteries via metallurgical design of negative electrodes while simplifying manufacturing processes. The team observed that the aluminum anode could store more lithium than conventional anode materials, and therefore more energy. —Liu et al.

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

The Australian Renewable Energy Agency (ARENA) announced a trial for a new type of electrolyzer which could see excess renewable energy stored in the gas grid and used to decarbonize Australia’s gas supply. Storing renewable energy directly in the gas network was a logical first route to market for the invention.

UNSW, H2Store to develop hydrogen storage for renewables; residential and commercial P2G

Green Car Congress

Professor Kondo-Francois Aguey-Zinsou and his team at UNSW’s School of Chemical Engineering have developed a system that provides cheap storage and transportation of hydrogen which they expect will provide a new alternative for energy storage within two years. We can actually store about seven times more energy than the current systems.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

And because such batteries could be installed and operated just like conventional solid lithium-ion batteries, without any of the auxiliary components needed for a lithium-air battery, they could be easily adapted to existing installations or conventional battery pack designs for cars, electronics, or grid-scale power storage.

Blue World Technologies takes 15% stake in Danish Power Systems; methanol fuel cell vehicles

Green Car Congress

The combination can be done without the implementation of expensive and cumbersome clean-up technologies which enables a simple and cost-effective system design. Waste heat can be utilized for cabin/battery heating and fuel tank can be placed where chassis design allows it.
