Volvo Buses in project researching use of second-life electric bus batteries to store solar energy

Green Car Congress

In Viva housing cooperative, Riksbyggen, Volvo, Göteborg Energi and Johanneberg Science Park have created a unique system in which energy from solar panels on the roofs of the apartment buildings is stored in batteries that previously powered electric buses on route 55.

IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. Renewable energy sources are central to the energy transition toward a more sustainable future.

IIASA study proposes solid air hydrogen liquefaction as efficient addition to hydrogen liquefaction supply chain

Green Car Congress

This is an expensive process and requires around 30% of the energy stored within the hydrogen. Solid Air Hydrogen Liquefaction (SAHL) consists of storing the cooling energy from the regasification of hydrogen, by solidifying air, and transporting the solid air back to where the hydrogen was liquefied. Montanari, P., Schneider, P.,

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

Green Car Congress

In the years ahead, it will be possible to produce it at low cost using wind and solar power, to store it underground for months, and then to pipe it on-demand to power everything from ships to steel mills. Renewable hydrogen can be made by splitting water into hydrogen and oxygen, using electricity generated by cheap wind or solar power.

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

Green Car Congress

The team observed that the aluminum anode could store more lithium than conventional anode materials, and therefore more energy. The group is also actively exploring other materials and microstructures with the goal of creating very cheap foils for battery systems. Support is acknowledged from Novelis, Inc. Sloan Foundation.

Topsoe and First Ammonia sign 5GW electrolyzer agreement for green ammonia

Green Car Congress

Green ammonia has the highest volumetric energy density out of all the hydrogen-based energy sources—much more than pure hydrogen—which makes it cheap and easy to store and transport. —Joel Moser, CEO of First Ammonia.

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.
