This doesn't feel like the most efficient, or lucrative, use of hydrogen. In fact, it's one of the least...

Vast majority of these are full battery electric, but there are a few plug in hybrids

Despite talk of an EV "slowdown", the % of new vehicles in the UK that are electric in some way continues to trend upwards...

The green hydrogen industry is saved!

Octopus Energy is now offering a free weekly coffee from Caffe Nero to customers with a smart meter. What a game-changer.

20. Thermal storage plus thermophotovoltaics. When electricity is abundant, heat is generated and used to heat blocks of graphite to over 2,000 C. This heat can be used directly, or converted back into electricity using thermophotovoltaic (TPV) cells (an explainer below).

16. Non-hydro gravity storage. When electricity is abundant, motors raise heavy objects (typically using tower cranes, or winches over mine shafts). When electricity is needed, objects are lowered and used to drive a turbine. @gravitricity is a key player.

7. Liquid metal batteries. High temperature battery that uses liquid metal electrodes and a liquid electrolyte. Charging the battery causes the negative electrode to get thicker, while the positive electrode gets thinner. When the battery discharges the reverse happens.

What are the best ways to store energy (or, more specifically, electricity)? A 2024 update to my list of storage technologies that will help enable a zero carbon grid.

Lots of people posting their favourite slides from @NatBullard 's annual presentation. I have to say, this is one of my faves... Not only are we deploying loads more solar and wind, we're getting better at it too.

I'm looking to learn more about decarbonising aviation. If you have any good articles, reports or podcasts, please send them my way.
