Developing Advanced Energy Tech @ Cedar Labs. 3X Founder, Lifelong Builder w/ Several Patents. 12+ Years in Deep Tech and Hardware Across Energy, Decarbonization and CDR/CCUS.

Currently Building Vulcan - a Modular, Carbon-Free CCGT Gas Turbine
We’re looking to build out the core team, so if any of this sounds interesting to you please reach out.

I’m also looking forward to connecting with other like minded individuals here. Let me know what you guys think.

This lead me to start a company focused on oxycombustion based power generation.

We’re developing modular units for energy intensive facilities faced with major challenges related to sourcing reliable baseload power and grid-related bottlenecks like 5+ year interconnection backlogs.

Because there’s no nitrogen in the combustion process, there’s also no NOX emissions and essentially no other pollutants/particulates.

The only “exhaust” is pure water. Seriously.

I truly believe that this will be the only way to fully decarbonize the use of hydrocarbons in power generation

Once the steam is condensed to water you get a pure CO2 stream that can be stored, sequestered, utilized, etc.

No additional energy is needed to separate out the CO2 making the cost/ton captured almost negligible.

Oxycombustion is a proven process. That’s how rockets get to space, O2 + fuel.

Oxycombustion is a semi closed loop-process that combusts pure oxygen with a fuel, without bringing in any outside air, in order to produce power through a modified gas turbine at very high temperatures.

The exhaust is pure CO2 and steam, making carbon capture much easier without trad CCUS capex

November 25, 2024 at 12:02 AM
This is because point source emissions are relatively low concentration (5-10%) with high particulate matter. Also capex for CCUS is very expensive and very energy intensive, requiring ~30% of a power plant’s net power output.

But there is a way to make it work.

Enter Oxycombustion

Attempts have been made, and others are in the works but it’s not an easy problem to solve.

Point source carbon capture has been touted as a potential solution but no projects have been able to hit anywhere close to their 90% targets. An EPA mandate by 2032

This has massive implications for global CO2 levels that have been on an absolute tear since the industrial revolution.

So if gas is here to stay, atleast for the foreseeable future, is there anything we can do to decarbonize it?
