Companies and countries are spending billions to make green energy from renewables, using it to extract hydrogen from water to generate electricity for cars and factories and to power combustion engines.

In most cases, we are discussing electric vehicles as a substitute and sustainable solution to reduce and avoid dependency on fossil fuel where we should also give attention to building infrastructure for hydrogen-driven vehicle manufacturing, refuelling stations etc. Sustainability point of view, hydrogen fuel vehicle manufacturing requires fewer carbon emissions than electric vehicle manufacturing.

If we can scale up, the cost of manufacturing and refuelling should be competitive and hydrogen refuelling might be cheaper than fossil fuel.
