Permanent sequestration of macroalgae and marine algae.
We need a holy grail of climate change solutions.
We need a carbon negative technology that is energy positive, with permanent sequestration.
True Carbon brings this process to the ocean - aquaculture bioenergy carbon capture and storage (ABCCS). It is also a process for cleaning up the ocean.
The feedstock is derived from marine debris or macroalgae farming. These sources of biomass are scalable and use existing CO2 that is diffused into the ocean.
They produce biomass that can be used for energy production, food production, and a variety of other projects such as phosphate fertilizer for growing food and forests on land.
This biomass comes from waste in the human food chain. Our waste goes directly into the global water cycle and creates algal blooms that feed on the nutrients and phosphate.
The biggest challenge comes from the process of anaerobic digestion and biosludge. Methane can easily be produced from this process. In some countries, wet-cold HTC pyrolysis is used, which converts the sludge into some components without using energy. It uses some of the inherent components of the sludge to dry it and produce a carbon substance and nitrogen and fertilizer substances.
Using steam in a biowaste plant to generate electricity. We want to recover the CO2 from the combustion of the biomass.
The pyrolysis step is not used in many industries - to get that oxy-fuel separation step.
“So that’s the main part we need to access for carbon capture and storage from these biological sources. It’s kind of the missing link in most bioenergies. It’s a natural energy resource.
As a pilot project, oxy-fuel capture in injection of basalt rock with carbfix.com areas we are looking at are the Caribbean.
True Carbon is working to figure out how much energy and what kind of energy will be extracted from this cycle. Could the energy be fed into the region’s grid?
Part of that puzzle is figuring out ways to convert biomass when biosolids are produced.
