I should have been more specific. I was trying to ask about generating renewable energy and then using that at some other site for heating purposes. What kind of efficiency does electricity to heat get you compared to just burning fossil fuels on site? I am not sure if that is the best way of asking this question.

Gotcha, I reread what you wrote andit makes more sense to me now.

What are your thoughts on using renewable electricity for heating applications as a way to displace burning of fossil fuels?

I am not an expert in traditional fermentation but I believe presence of contaminants depends on the crop, the strain of yeast present during the process, and conditions. So basically it can vary a lot.

I haven't read the link yet, but did not expect synthetic alcohol to be used for food and beverages.

We ferment CO2 + H2 rather than syngas (CO / CO + H2 / CO + H2 + CO2) but yes gas fermentation is not new technology.

Like traditional chemical processes which use metal catalysts, superior catalyst design improves the performance and ultimately the economics of the process.

Edit: I should have mentioned that it's not just the catalyst that has been improved, the design of the process itself has been improved. So upstream (gasification) and the design of the bioreactor also impact how well the process works.

Thank you.

We are building the frameworks so that we will be able to take advantage of this but haven't yet. Can message me via the webform on our website? I would love to learn more about HPC, my understanding is limited.

From my understanding, OER occurs when splitting water into oxygen and hydrogen and can happen in biological and electrochemical systems. In the former plants use energy from sunlight to extract the electrons from water whereas in the latter, energy from electricity is used. In our process we use hydrogen that is oroduced elsewhere, it isn't part of our technology so we don't run into this issue.

Multiple solutions are needed to address climate change and CCU is just one of many levers we can use to decarbonise our industries. Sure CCU isn't as direct as DAC, but coupling CCU with biogenic sources of CO2 can create a carbon negative process if the product doesn't degrade. Solvents may not fit the bill for storing carbon for centuries, but plastics do.

The more immediate impact for CCU is the emissions reduction achieved via displacement of fossil derived solvents.

Didn't know that! I assumed it was always captured elsewhere.

As we find new profitable uses for CO2 the demand for it will increase, which should help create new carbon value chains.

They don't live in ethanol and water but it has been tested and they can survive quite high concentrations of ethanol.

And yes they could convert CO2 into recreational drinking fluid, and I learned from someone else in this thread that it would be totally legal!

I definitely underappreciated how important communication is.

I would describe hydrogen as an energy carrier rather than an energy source. Hydrogen is always made from something else, and the energy is either provided by that something else, or indirectly from another source, or a combination of both.

If you use an electrolyser to make hydrogen from water, your energy source is actually the electricity used to drive that reaction. The energy is stored as hydrogen gas.

Large bodies of water are great passive systems to capture CO2. For the outdoors, and if using sunlight is the energy source, algae and seaweed are definitely great candidates for capturing CO2.

Unfortunately your idea wouldn't work for our microorganisms as it is anaerobic, so it would die if exposed to air. But I like your idea for using sunlight to improve the growing conditions of algae + using automation for harvesting!

You're absolutely right regarding enthalpy and thanks for fixing the typos. I am still trying to find the best way to communicate what we are doing.

I find it ironic that carbon capture and storage technology was originally (might be wrong here) developed for enhanced oil recovery (EOR).

But yes we really need better systems to incentivize the capture and storage or utilisation of CO2. Carbon taxes a great place to start.
