Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

To meet this challenge and to satisfy the constant energy demand of society, electricity must be stored in times of overproduction to provide energy when little sunshine and wind is available. To store the green electricity in a highly scalable way, it must be converted into chemical energy. Diess et al.

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. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking.

SoCalGas, H2U testing new Gramme 50 electroylzer for green hydrogen production

Green Car Congress

According to early analysis, the cost target of the new technology is half that of current electrolyzers and the total cost of ownership over its life is expected to be 75% less. Green hydrogen offers the ability to store renewable electricity across months and seasons, an advantage over battery storage.
