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

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.

A DIY E-bike Conversion on the Cheap

Online discussions convinced me, however, that this is the expected behavior when commanding a motor to maintain a fixed amperage in its windings (thus applying constant torque) while under little load. With the power setting fixed, the wheel would spin increasingly fast and the amperage drawn from the battery would steadily increase.

Cemvita demonstrates “gold hydrogen” production in situ, sets up subsidiary

Green Car Congress

Traditional methods of producing hydrogen without greenhouse gas emissions (green hydrogen) include electrolysis powered by renewable sources such as wind, solar, or hydro. —Zach Broussard, Director of Gold H2 at Cemvita. According to recent studies, the global green hydrogen market size was valued at US$0.3 billion in 2020.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

The magnitude of these savings is ~5% to 15% higher in a system with 20% wind penetration compared to a system with no wind power, and the savings are 50–60% higher in a system that requires capacity expansion. Controlled charging can also take advantage of the high levels of wind generation that commonly occur at night in the US.

Credit Suisse Predicts Renewable Energy That Is “Too Cheap To Meter” By 2025

CleanTechnica EVs

Credit Suisse says the Inflation Reduction Act will have such a tremendous impact on renewable energy that the US may see the levelized cost of electricity from renewable sources fall to less than 1 cent per kWh hour by 2025 after factoring in all tax and production credits. Now, before we get all gaga over […].
