31 results about "Ocean acidification" patented technology

Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. Seawater is slightly basic (meaning pH > 7), and ocean acidification involves a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7). An estimated 30–40% of the carbon dioxide from human activity released into the atmosphere dissolves into oceans, rivers and lakes. To achieve chemical equilibrium, some of it reacts with the water to form carbonic acid. Some of the resulting carbonic acid molecules dissociate into a bicarbonate ion and a hydrogen ion, thus increasing ocean acidity (H⁺ ion concentration). Between 1751 and 1996, surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14, representing an increase of almost 30% in H⁺ ion concentration in the world's oceans. Earth System Models project that, by around 2008, ocean acidity exceeded historical analogues and, in combination with other ocean biogeochemical changes, could undermine the functioning of marine ecosystems and disrupt the provision of many goods and services associated with the ocean beginning as early as 2100.

Transforming energy and transportation into primary engines for reversing global warming and eliminating ocean acidification

The invention encompasses multi-stage naturally amplified global-scale carbon dioxide capture systems combining basic capture from (CC—carbon capture) clean-coal-fired and CC gas-fired power plants, natural-gas reformation systems, cement plants, outdoor air, home and building flues, incinerators, crematoriums, blast-furnaces, kilns, refineries, factories, oil gasification systems and coal gasification systems which yield concentrated carbon dioxide, with a collective, globally distributed capture capacity of up to 3 GtC / yr, feeding the captured carbon dioxide into land-based invention stage-1 bioreactors for rapid, selective, high capacity conversion to a high-density, fast-sinking marine algae by means of accelerated photosynthesis and / or coccolithogenesis (calcification) consuming carbon dioxide as the algae bloom, and transporting the stage-1 bioreactor-produced algae to seaports for seeding the oceans at regular intervals in stage-2 operations-at-sea to produce naturally amplified 14 GtC / yr algal blooms at sea, the stage-2 operations circumventing classic prior-art (and natural) ocean fertilization limits of low bloom rate, grazers eating algae seed before it blooms, interfering buoyant strains which don't clear the photic zone to allow light penetration for multiple blooms per year, and proximal post-bloom anoxia. A total invention CO2 capture and safe storage capacity of 17 GtC / yr (land and sea) is projected during fair-weather, and a 40% foul weather down-time allowance ensures that an average 10 GtC / yr of impact capture would result. If emissions are concurrently capped by at 12 GtC / yr by 2023, with invention-assisted reduction to 6 GtC / yr by 2050, 3 GtC / yr by 2062, and 1 GtC / yr by 2078, atmospheric CO2 will be reduced to 280 ppm by 2075.A spin-off technology includes hydrogen (H2) production by natural-gas reformation—enough H2 to fuel a significant fraction of transportation by 2050. Spin-off side benefits of the invention system include restoring ideal ocean pH and re-proliferating decimated marine populations, restoring them to levels last seen in the 18th to mid-19th centuries. Additional spin-off applications of invention bioreactor algal production include silage, animal feed, feed supplements, fertilizer, biofuels, food for fish and mollusk farming, cleansing lakes and rivers of bacteria and agricultural run-off, and elimination of coastal water HAB's (harmful algae blooms), such as the notorious “red tide” in Florida.
