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. The technology is estimated to have a global potential of 7 to 70 TWh, with most of this potential concentrated in China, India, Russia, and the US. Dabek, P.B., Brandão, R.,

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. trillion of that going to wind and solar and a further $1.5

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. The novel system shows potential for tackling global problems in a patient, thoughtful, and human-scaled way. The apparent contradictions do not end there.

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

Green Car Congress

One of the challenges of constructing a global hydrogen economy is hydrogen transportation by sea. This is an expensive process and requires around 30% of the energy stored within the hydrogen. The hydrogen is liquefied where electricity is cheap. One option is to liquefy hydrogen, which requires cooling to 20 Kelvin (-253 °C).

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). Storing and moving hydrogen is challenging.

Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity? Instead, that pure status is now reserved above all for wind and solar. stores of energy , as reservoirs for drinking water and irrigation, and for recreation and aquaculture.

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

Green Car Congress

Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. 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.
