Solving the engineering challenges of "useful amount of time when the grid doesn't need any gas" without also digging into why the UK's energy pricing structure is such an outlier at the expense of consumers, seem a bit like one of those doomed attempts to solve a social issue by purely technical means.
While that is a slightly different cause, "banning nearly all construction of onshore wind" was and is a social issue. It's culture and politics, not engineering.
