A few months ago, Bosch announced that it had developed a process that would reduce nitrous oxide emissions from diesel engines, down to about a fifth of future legal limits. This (if it's true) should prove to be the saviour of diesel cars - so why is this not being taken notice of ?

There has also been mention of development of solid state electric cars, (i.e. no heavy batteries). Surely, the ideal car for the future would therefore be a hybrid with a near-non-polluting diesel engine (with the Bosch process reducing nitrous oxide to negligible amounts), paired with an electric engine with lightweight solid state 'batteries'.

Bosch was also the supplier of the emissions cheating software found on VW cars... 😬

There's still the CO2 emissions to consider, which would still be well above an equivalent EV in a lifecycle comparison. Even full EVs will desperately struggle to meet long term CO2 targets, so diesels have no chance at all.

Solid-state batteries may well become the future, but they will still be fairly heavy. Maybe at some point in future EVs may become inherently lighter than their equivalent ICE counterparts due to large improvements in battery power density, but that point is still a very long way off. That's why current EVs are generally heavier and have shorter range than ICE cars. But the gap is gradually closing in as the tech progresses.

Solid state batteries are very heavy.........

Well they are being touted as being much lighter than current Lithium-ion batteries, which among other things is a major reason why research is pushing in that direction. I know that BMW, VW, Hyundai, Samsung and Panasonic are already investing in the research in funding various start-ups. So far though it's all vapourware with no sign of any meaningful production until 2025-2030.

Stating that they are "very heavy" doesn't really mean anything to me. It's all about relative weight. An internal combustion engine is "very heavy" too. At present an EV is significantly heavier than a direct equivalent ICE (typically in the order of a few hundred kgs), but solid state batteries may close that gap or possibly even eliminate it altogether - but it's too early to make that call yet unless you have some serious inside knowledge?

Nasa are working on liquid batteries, estimated at twice the power of Lithium IOn. Probabably many years until available for cars, if ever.

Interesting development. Twice the energy density of Li-ion would be a huge step forward. Also interesting that it appears to eliminate the fire risk of both fossil fuels and Li-ion batteries. I wonder what the projected costs are at present? I didn't see anything on that in the article.
