Scientists have increased the life of fuel cells – why that matters for solar and wind

Electrek

In research that could jumpstart work on a range of technologies including fuel cells – key to storing solar and wind energy – MIT researchers have found a relatively simple way to increase the lifetimes of these devices: changing the “pH” of the system.

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.

BloombergNEF: solar, wind, batteries to attract $10T to 2050; curbing emissions long-term will require other technologies

Green Car Congress

Deep declines in wind, solar and battery technology costs will result in a grid nearly half-powered by the two fast-growing renewable energy sources by 2050, according to the latest projections from BloombergNEF (BNEF). Wind and solar grow from 7% of generation today to 48% by 2050.

Hydrogen Battery "Sponges" Store Solar for the Grid

Cars That Think

A novel project in Australia aims to harness the sun’s energy in two different ways: by storing it and by using it to produce green hydrogen. Dozens of solar farms in the country’s southeastern region are slated to use “ hydrogen batteries ” in coming years. All together they’ll represent a 300-megawatt solar installation.

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
