As the world wakes up to the climate change crisis, scientists are looking for ways to cool our world. Part of the problem is our reliance on fossil fuels - transport accounts for 25% of global CO2 emissions. RAZOR’s Emma Keeling is in Iceland to visit Carbon Recycling International who are converting CO2 into renewable methanol for fuel applications, greener chemicals and other products. At scale, this has the potential to create a circular carbon economy.

The last time I checked, the price for 200L of Methanol was close to $700 CAD here in Canada. As long as we get this price down and make a dependable infrastructure, I see it as a much more practical green fuel. Driving a hybrid car that can use M100 and also gasoline (when needed) with the price of a regular hybrid would help everyone switch to the real green economy.

@@steveciarico9824 syngas, biogas, and landfill gas (which continuously output fuel for 50 years straight and landfills over the years are everywhere) are also suitable for making carbon neutral methanol fuel. Basically any biowaste is with either a gasifier or a biodigester and the already made and in use methanol synthesis reactors. Heck for syngas you are left with char as a byproduct which if you burry it in the form of biochar (which has soil fertility Benifits) , you are sequestering carbon; yes a carbon negative fuel that is net energy positive to make. Biomethanol in general is net energy gaining process unlike efuel which is a net negative electric storage and distribution tech. Did I mention methanol takes way less enery to split into hydrogen, while taking up less space and container weight and being vastly easier to transport. China actually made a methanol to hydrogen refueling station for this reason. They also have trucks and cabs that run on internal combustion engine methanol. Though with a relatively inexpensive gasoline to alcohol conversion kit (compared to buying a new car) 90% of vehicles on the road can be converted. In truth methanol is cheap (the drag racer people stimulated a arbitrary price mark up over the decade and renewable suppliers of methanol is a new sector that lacks producers). US goverment found it was $0.70 a gallon if we used non renewable natural gas (though bio methane from literal sewage and trash should be in the same ball park). Biomethanol can be just as if not more inexpensive. Though E-methanol will be a lot more expensive since it is a net loss of energy by storing in a more convenient and applicable form.

@@wastelesslearning1245 If you converted an engine to run on methanol it would cut it's mpg in half that is well documented by within the US Department of Energy Alternative fuels fuel properties comparisons using the gasoline gallon equivalent metric. The reasons drag racers love methanol is the godly cooling effects of the fuel vaporizing allows them to fill the block with a solid material to strengthen the block as radiators are not necessary. Ideally, it should be blended with gasoline to boost octane and reduce combustion chamber temperature allowing higher compression engines increasing efficiency.

Electrolysis to produce hydrogen is ~70% efficient, then the efficiency of methanol synthesis from hydrogen and CO2 is typically around 40-50%, Then you could expect around 35% efficiency for a methanol internal combustion engine. So a round trip efficiency of just over 12%. How are we looking so far?

True. Electric Cars are inherently more energyefficient. Then you can add a small metanolgenerator. And use that to heat the car. And extend the range. (When needed) Thus saving massively on batteries.

If the process uses high temperature nuclear hydrogen and nuclear waste heat for the CO2 stripper tower heater, the process can be cheap and scalable. In this case it uses cheap hydro and geothetmal electricity and heat.

Seems like the efficiency is pretty low if you have to do electrolysis, pressurization, distillation etc. Is it possible to produce methanol directly from electricity CO2 and water? Can you reverse the process in a direct methanol fuel cell?
@markotrieste

Nope, hydrogen in the water is locked in an energy well, you have to pull it out via electrolysis. You should think of methanol as a carrier of hydrogen.

The challenge in converting to a non- fossil fuel economy is to create a power delivery system using clean, abundant nuclear energy. Batteries are one way; expensive, short-lived, and made using scare rare earth metals, amd building a completely new infrastructure (charging stations), or produce clean-burning methanol, which can be delivered using existing petrol stations with minimal mal modifications. The Methanol economy is probably best realized by combining this fuel with 15% gasoline, useable in flex fuel vehicles. The push to all-electric vehicles is because of graft; some are getting very, very rich. See: Elon Musk, Al Gore, etc. The best system

@@scottslotterbeck3796 running the world on nuclear power may have kind of made sense if it was pushed for 20-40 years ago. But unfortunately nuclear power is simply too expensive now. Renewables are much cheaper at this point, and nuclear power has only become more expensive. Likewise the promise of fusion power is laughable: even if we get net positive energy, fusion will likely always be more expensive than fusion power, which will always be more expensive than collecting the energy that reaches us for free from the powerful fusion generator in the sky
@sandpiperbf9767

Likewise batteries have real advantages over other power storage methods in that they have near zero round trip energy losses. No liquid fuel will ever achieve this even with advanced fuel cells. I agree though that the rare materials required to create li-ion batteries means it probably will not be the storage system we need to manage power on the largest scales.

For marine application it is more suitable. Battery systems do not have enough energy density. Recharging time is too long. İt is too difficult to storage hydrogene. Systems need too high pressure and extreme low temperature. Leakage is a significant problem. System can be very expensive. transporting hydrogene is a different story. İt could be very expensive too. Amonia is too hazard gas. At room temperature it is at gas phase. Leak is a big problem. Storage systems can be too expensive. To burn it systems need modifications. Explosion is another problem. Transporting Amonia is difficult. Systems need possitive pressure to storage Amonia. Methanol is more suitable than amonia. Global warming is too big problem. a too big environmental desaster is closed to world. Every country decides and makes something for global warming quickly. Time is too limited.

Methanol is toxic fuel the best use of CO2 gas is for methanition using the Sabatier reaction which means any spare hydrogen can be converted into CH4 and water . CO2 gas can be pumped into depleted gas fields for storage.

Not true! As long as you have a cheap source of electricity you can do it. For example from the sun. If you live in a place with low geothermal activity but a high level of sunlight with a large enough sun farm you produce tons of electricity for effectively free (minus farm costs of course).

@@tasimota but looking at the experiments showing co2’s heat absorption, we’d need nearly 100 times that 400 ppm to produce the heat gains they’re claiming, which would prove that co2 isn’t the driver they’re making it out to be.
