It depends on how storage tech develops, but natural gas turbines will continue to play a role for the foreseeable future. However, that role will increasingly be as contingency/backup for times of scarcity rather than as a continuous baseload. They will only be used during demand peaks that correspond with unfavourable weather conditions, or other unusual scenarios. This is similar to the current role of the UK's few remaining coal plants. (I should also note that natural gas use is already in decline in the UK, as is gas turbine generating capacity)
