CO2 Hydrogenation to Methanol

Thank you for your work Dr. Urakawa's. I always knew this was possible, ever since I took chem 101, early on in my engineering education. I was always interested in this technology, and have been always thinking about this as the way we can move forward. Very impressive results, and its a very feasible technology. This can be used today. However, its not the technology as we know, its more of the political will to implement the technology. Brilliant set up as well. Thank you again, and I look forward to mass use of such technology in the future.

That is interesting to me, i've been brainstorming about this for a while now. Finding an effective medium to store hydrogen and reducing the co2 in the atmosphere. Thanks for your research!

[@MathewZ788]

Well yea you are technically right we are reducing the co2 levels but once you burn that methanol as fuel it's going back into the air nothing on earth will ever reduce the weight on earth or increase it. It's kinda awesome thinking about this and the technology we may have in the future.

[@topsecret1837]

Mathew Zacharia Just because you’re burning the methanol doesn’t mean the waste products have to go back into the environment. It’s a matter of reducing the co2 levels and isolating the total mass of it to a level the environment can handle, while taking the excess and circulating it by electrolyzing water for hydrogen and using that to convert back into methanol. Of course this can not produce infinite energy as even if the cycle can be rapidly done mass losses due to mass-energy conversion during combustion would require more fuel sources (fortunately earth accumulates millions of tons of mass every year from space, so that isn’t a problem).

[@MathewZ788]

@@topsecret1837 That is true but I didnt say that you cant capture the co2 back into water and reutilise to make it back into methanol. This reconversion/ capture of co2 cannot be done in an automobile as it wouldnt be able to handle the weight of the car as well as the capture tank.

[@dansw0rkshop]

There are two energy inputs that aren't mentioned. 1. Hydrogen and 2. compression to 360 bar. You have to burn something (or use nuclear) to supply these inputs. All I see is a change of energy forms, which to be fair may be useful. When you burn methanol in an engine or a fuel cell, it turns back into CO2 again.

[@trs4u]

Did Dr Urakawa get to scale up as he wished?

[@danielheckel2755]

No

[@dalsenov]

It seems to me that everything revolves against the same problems over and over again.In order to convert an energy depleted compound (such as CO2 or water) one has to give back that energy (or a little more) somehow.This solutions usually mean either high temperatures,high pressures,expensive catalysts (platinum,paladium, group etc. that cost at least 36 millions USD/tonne).Yes we need to find a truly revolutionary catalist or to link the catalyst realm with the nanotechnology field and hope for a miracle discovery.Many advocate that the "hydrogen economy" is complicated and needs high infrastructure and thick pressure tanks (350-700 bars) and advocate instead "the methanol economy" but we arrive at the same issues (400 bar pressure).Not to mention that methanol has about half specific energy (20 MJ/kg) comparing to gasoline (44) and far from hydrogen (142).Also we talk about mixing methanol with gasoline but in EU there is a maximum 3 % limit concerning methanol mixing with gasoline.I listen to the same well known introductive parts about pretty well known things ,over and over again, hoping for a breakthrough.Unfortunately, no news so far.

[@dutchtulip1258]

Methanol could be converted to DME. Dimethyl ether is as substitute for propane and is also a promising fuel in diesel engines, and gas turbines. For diesel engines, an advantage is the high cetane number of 55, compared to that of diesel fuel from petroleum, which is 40-53. Short carbon chains lead to very low emissions of particulate matter.

[@dalsenov]

@@dutchtulip1258 Yes but DME is a gas and needs pressurization (around 5 bars).All costs will increase comparing to Diesel (2x lower specific energy means shorter car range,more costly fuel transportation and storage ,pressurization equipment needed,safety issues,etc.And the CO2 problem still remain.

[@elfillari]

As we now (2021) know, the methanol used as fuel cell via reformer, will contamined the system useless in about fiew thousand hour/km later. Then re-installation the new system to the vehicle will be over expensive! That is why for.ex. Nissan gave up their fuel cell NV200 projects in the year 2019.

[@Resologist]

Like far too many research efforts, converting carbon dioxide into a fuel that will be oxidized again, (a net-zero fuel), requires an energy input. Catalysts, high pressures, very low temperatures, and hydrogen gas generation would undoubtedly require an industrial plant; but, what is your alternative energy source? Nuclear, solar, wind, hydro dams, geothermal...? The reason that fossil fuels are used is their abundance and cheap production; thus, your process needs to be more economical than drilling an oil or gas well, or mining coal. If your methanol costs more than fossil fuels, it's not a worthwhile technology.

[@shahroozazimi9150]

Very good ,Thank you

[@kenrowe167]

But what is the point of this process? Firstly, you need liquid co2 (produced by an industrial, energy-consuming process). Then you need (hopefully green) hydrogen, produced by electrolysis - which, with present technology, is an inefficent and non-cost-effective process. And then there is the energy consumed by your own process. All to produce methanol to burn and release co2. Why not just burn the hydrogen? The only exhaust products are heat and water!

[@trs4u]

The most important reason is the most mundane one - we don't have "hydrogen burners". Everything works on carbon chemistry, and even if we (for example) banned carbon (I think this is a ridiculous idea) chemistry - all those things will continue to exist and people will want to use them for *decades*. Changing everything is an affront to reason and people's pockets. If we changed just how we supply carbon chemistry, it's only an affront to people's pockets, and a slowly-building one at that. Sliding over slowly gains us at-scale hydrogen production and carbon capture. If people start buying hydrogen burners, the supply will be there ready for them.

Even better is the notion that the co2 for this will come from the atmosphere. Good luck processing thousands of cubic meters of air to get the required CO2. Problem being that co2 makes up only about 0,03% of the atmosphere

well, the process is interesting, but I hardly see it as a viable way to convert CO2 from fossil fuels combustion into a useful product. here CO2 is pure and already compressed and liquefied. in real world conditions CO2 is a lot, diluted and at ambient pressure. CO2 capture (by means of amine absorption for example) and compression is very energy-intesive.

The methanol will ruin the reformer before the hydrogen fuel cell (reformer combines the hydrogen out of the methanol, then feeds the Pure hydrogen to the fuel cell). This reformer last only fiew thousand hours, then it needs to be replaced! Cost a fortune run with methanol fuel cell vehicle! That is why Nissan stopped their NV200 methanol project in 2019.

1. How much energy is needed to obtain H gas? 2. The atmosphere contains only about 400 ppm of CO2, so how much energy is needed to obtain CO2? 3. Plants need CO2 for photosynthesis to give us O gas and food. Chemically speaking and in practice, higher CO2 levels lead to more plant growth. The pitiful level of 400ppm (0.04%) plays little impact on 'global warming'. The activities of the SUN and water vapour/clouds play a HUGE role in regulating our climate. THINK!!

[@dutchtulip1258]

Using biologically inspired membranes, the energy to capture CO2 can be greatly reduced. Storing energy from solar is going to be a priority as more people switch to this free form of energy.

[@llanlydia]

1. Very little. 2. CO2 isn't/won't be obtained from the atmosphere only, although there process doesn't require that much energy as it's a side product in most gas manufacturers. I reckon it will also be taken straight from the factories where CO2 is produced. 3. Go to school for once, silly. 400 ppm (parts per million) is equivalent to 0.0004% and that is almost DOUBLE the CO2 concentration in the atmosphere before the industrial revolution. Also, you can't blame water vapors and the sun on the earth heating up at an unnatural rate. It is very artificial, thus caused by humans and, not only because of CO2 emissions. Also, we're producing more CO2 than plants can consume PLUS the deforestation. THINK!
