What about methane?
There are already commercial processes in place to capture it from landfills, and there are industrial processes that can produce it from hydrogen with an 8% energy loss. So if the green hydrogen problem is solved that could be used here.
A lot of Asian countries already have cars that run directly on CNG - from the factory -, as it produces less smog than petrol or diesel. I visited India recently, and I'd say 80% of vehicles I saw ran on CNG (they have a hazard label).
Maybe the most important thing is the infrastructure to distribute it is already there in most countries.
- WheelsAtLarge 4y agoMethane is a greenhouse gas. It's more polluting than c02. Removing it from the environment is a good thing but creating more is not a good thing for global warming. I suspect for it to be an alternative to oil, an such, we would need to create it not just remove it from landfills. Compressed natural gas is mostly methane but we are trying to move away from fossil fuels so it's not a long term solution. Here's a link that gives some info on it: https://www.reuters.com/article/us-usa-gas-climatebox-explainer/explainer-cleaner-but-not-clean-why-scientists-say-natural-gas-wont-avert-climate-disaster-idUSKCN25E1DR https://www.reuters.com/article/us-usa-gas-climatebox-explai...
- leetnewb 4y agoI don't think that is a good comparison. Fossil fuel is a carbon sink. Extracting methane from fossil fuels in the ground releases the carbon from the sink and into the atmosphere. If synthesizing methane from hydrogen grabs carbon that is already present, it is carbon neutral.
