Now super capacitors too
We will have to wait for it to be in the shops.

 Methane has half the carbon of a long-chain liquid hydrocarbon. In
most situations, a 2:1 improvement is considered to be pretty good.

But in the current situation a 2:1 improvement isn't good enough.
We have to cut our carbon emissions right back to stop global warming - the aim is to get the atmospheric CO2 level back to the regular inter-glacial 270ppm.

CNG cars work.  But the greenies hate methane.

For good reason.

As they hate nukes and hydro power.

For very different reasons.
They aren't enthusiastic about nukes - we still haven't got an acceptable way of dealing with nuclear waste. It does stay dangerous for abut 100,000 years.
The aren't all that enthusiastic about flooding valleys to create hydro-electric reservoirs. It does mess up the local environment, and always seems to drive some species or other to extinction.

They hate energy.

They don't. They just have reservations about some of the ways we generate it.
This is good example of you expressing yourself clearly, but expressing unfortunate opinions you have picked up from climate change denial propaganda, which you should have been able to recognise as fatuous nonsense but have swallowed, hook, line and sinker.
