Rachel Reeves was on the radio this week extolling the virtues of Hydrogen.

Was there surplus interconnector lecky available from abroad but the
price was wrong compared to gas generation?

I don’t collect data on other sources of energy input, but my impression is that the interconnectors were melting with all the energy we were
importing,

There is next to no "green" hydrogen in the uk and more generally it
cannot be distributed via the existing gas grid pipeline as hydrogen is
too small and would leak through those pipes.

I get the impression that Rachel Reeves doesn’t know much about hydrogen…or electricity…or gas…or solar…or the interconnectors…

I took the gamble of going for the Octopus tracker tariff (October
version and my region seems to be more expensive than most). For the
whole of November I paid around the same as the capped rate for both gas
and electriity. December and January I paid significantly more than
their fixed rate, at rate lower than the capped rate. There were only a
few days when the price fell below the fixed rate by more than 10p/unit
for electricity. I can confirm that the prices were high(er) during the multiple Dunkelflaute events when demand was also high.

I’ve been on an Octopus fixed deal for some months, and out of curiosity recently looked up the current prices for their Variable tariff.

I’m very glad I fixed when I did!
