> The 50MW facility near Manchester will store enough power for roughly 50,000 homes.
They keep doing this with grid storage projects. The number they need to quote is watt-hours. 50MW for how many hours? That’s the only relevant metric.
Driven a lot by intentionally deceitful marketing too IMO. The PR person at the company behind whatever storage project only quotes those numbers in these terms (enough to power 50,000 homes) because they sound impressive, and as you say the journalist doesn’t know better so they then print it like that.
> Its proprietary technology uses liquid air as the storage medium and can deliver anywhere from 20 MW/100 MWh to more than 200 MW/2 GWh of energy and has a lifespan over 30 years.
