Hello everyone,

it seems that Tesla Semi trucks won't be produced this year, so that the only option to decarbonize trucks may be CNG & LNG trucks. In China LNG trucks account for 10% of market share, in Europe 3-4% growing double digit. US market is still lagging..do you think US will ever catch-up? 

I wrote a few blog-articles on SeekingAlpha on natural gas mobility, focusing specifically on a company called Westport Fuel Systems. Let me know what you think.

If you aren't familiar with the Sabatier reaction, look this up. The chemical reaction is 4H2 + CO2 -> CH4 + 2H2O. This has been understood since the late 1890's and Raney Nickel-based reactors have been around since the 1920's.

There are various processes for converting methane to methanol or propane, either of which is a liquid fuel without extreme pressure. Methanol is liquid at room temperature and propane becomes a liquid at relatively incidental pressures. Recent discoveries (recent meaning since the start of 2021) are showing new ways of producing methanol from methane under room temperature and pressure conditions, or producing methanol directly from CO2.

Methanol (COH4) breaks up into synthesis gas (CO + 2H2) with mild heating, and is usually used as the starting point for making gasoline or diesel using Fischer-Tropf synthesis.

Natural gas is 'cleaner' than diesel, but difficult to handle. Propane is a commonly used mass transit fuel and is nearly as energy dense as diesel. The issue at this point is figuring out how to make methanol or propane from natural gas 'at the source', meaning at the point of emission, so that the collected product is easy to transport. Methane emissions are being found with distressing frequency - there is considerable value in figuring out how to intercept these emissions and make them commercially useful.

At one end, the technologies for natural gas storage and transmission are getting more and more effective, but at the other end, NG conversion to liquid fuels is also getting easier.

the company I mentioned is active in propane mobility too, but main business is related to a HPDI lng technology, whose benefit is to have identica torque power of a diesel truck but with emissions like a natural gas one
