What sorbent is used to capture the CO2 from ambient air in the air- capture collector?
GRT used sodium hydroxide (NaOH) in its very early work on CO2 air-capture. Currently a different sorbent which is proprietary in nature is used. This new sorbent represents a major step forward in air-capture as it greatly reduces the energy consumed in the process and avoids the toxicity issues associated with sodium hydroxide (lye).
- What are the specs of the optional CO2 scrubber? Can the scrubber be used to pull CO2 out of air used for purging?
- Can an ambient air respirator be used in environments that are Immediately Dangerous to Life and Health (IDLH)?
