STEP 25 GGS - The Gas Grabbers - page 2
Introduction
Impact
- Each machine releases 20 tons of juvenile diatoms per day for 20 weeks = 400 tons pa
- These grow to form 11 million tons of adult diatoms.
- Those that are eaten enter the food chain, which locks up 0.3 Million Tons of CO2 per year however their empty skeletons trap an additional 4.5 of CO2 per year while intact diatoms sink to the ocean bottom, locking up a further 4 Million Tons of CO2 per year
- Total 8.8 Million Tons of CO2 absorbed.
Practically
- Breeding and selection of diatoms is already proven in principle.
- The breeding station would be combined with another machine, eg Ocean Heat Shuffler
Environmentally
- The GGS is totally wave-powered using renewable energy.
- These Diatoms could not self-propagate in the open sea at summer temperatures
- Huge amounts of CO2 are locked up
Socially/ Politically
- Such projects could be financed by a Carbon Tax; ideally through a “World Carbon Bank”
- Governments could buy in to such schemes; it’s jobs for their industry and a way to be seen to be doing something!
Economically
- Development costs are estimated at $100 million
- A full-size facility would cost €10 million per annum to run.
- Diatoms absorb 8.8 million tons of CO2 per annum, worth €114 million at €13 per ton.
- Payback time for investors… Less than one year!
