A non-life process making glucose from carbon dioxide and water using electricity or light? update (Sept. 2018): Here is a bit of news that someone might be inclined to cite in a &quot;No, not yet, but...&quot; answer.

NASA has announced a CO2 conversion challenge!

Get out of your element! Convert CO2 into molecules to power bio-manufacturing in space.
Convert CO2 to Glucose:
Help us discover ways to develop novel synthesis technologies that use carbon dioxide (CO2) as the sole carbon source to generate molecules that can be used to manufacture a variety of products, including &quot;substrates&quot; for use in microbial bioreactors.
Because CO2 is readily abundant within the Martian atmosphere, such technologies will translate into in-situ manufacturing of products to enable humans to live and thrive on the planet, and also be implemented on Earth by using both waste and atmospheric CO2 as a resource.

It looks like this will be a multi-year project.


original question (Mar. 2017):
A large mass fraction of foodstuff a person would need on a long trip (for example, in space or otherwise not on Earth) would come from its caloric (energy) value. Scenarios have been explored for decades to use solar photovoltaic (or other electric) power to generate light to grow plants locally for food. Light provides energy for photosynthesis which combines $\ce{CO2}$ and $\ce{H2O}$ and makes glucose, (later converted to and stored as starch) which then provides caloric value to food.
$$\ce{6CO2(g) + 6H2O(l) -&gt; C6H12O6(s) + 6O2(g)}$$
I'd like to know if a purely non-life based self-contained chemical process has been developed or is at least close to continuously converting $\ce{CO2}$ and $\ce{H2O}$ to glucose, using electricity directly, or electrically generated light.
By &quot;non-life based&quot; I mean it's not a bioreactor based on living cells. It could certainly use processes that are similar to those used in organisms.
The process would have to be potentially able to run stand-alone with minimum consumables, in the same sense of the term &quot;process&quot; as is mean for the Haber Process.
I am not asking if you think it could be done, but if there is a way that it could be done, based on well-documented research towards implementing complete Artificial Photosynthesis using light or electricity, not just a demonstration where a laboratory technician regularly adds separately prepared reagents and precursors for each step.
Popular research these days for CO2 fixation involves the following enzymes with associated conversion rate:

RuBisCO - 10 molecules/sec
ECR(Enoxyl-CoA carboxylase/reductase) - 80
molecules/sec

The major noncarbohydrate precursors are lactate, amino acids, and glycerol.

CO2 reduction -&gt; Hydrocarbon eg. Formaldehydes/acids (CH2O).
Then Formose/Butlerov reaction (catalyst:base+Ca/Mg) -&gt; sugar
