CCRES: Carbon capture and consumption

CCRES: Carbon capture and consumption | Sustain Our Earth | Scoop.it

Could it Eliminate the Need for Wastewater Aeration? Algal blooms have always proved a challenge for the water industry. Yet could this organic matter,with the help of wastewater nutrients, be turned into a biofuel and help alleviate fossil fuel shortages? Tom Freyberg investigates the European funded All-Gas project. First generation biofuels from crops never really bloomed into a fruitful harvest. Opponents criticized using up valuable land to grow crops and fuel the cars of the rich, instead of filling the stomachs of the poor. Second generation biofuels – made from biomass - have proved a lot harder to extract the required fuel and fully crack. And then along came algae. Unlike first generation biofuels, algae can be grown using land and water not suitable for plant and food production. Consuming solar energy and reproducing itself, algae generates a type of oil that has a similar molecular structure to petroleum products produced today. As if this wasn't enough – algae growth also consumes carbon dioxide, a known major greenhouse gas (GHG). As a result of the apparent benefits the race is on to commercialize second and now third generation biofuels, in the case of algae. Continents and companies are putting money where their mouths are to find out how what we thought was simply a green weed growing in the sea could be the answer to inevitable fossil fuel shortages.

Human domination of the biosphere: Rapid discharge of the earth-space battery foretells the future of humankind

Human domination of the biosphere: Rapid discharge of the earth-space battery foretells the future of humankind | Sustain Our Earth | Scoop.it

Earth is a chemical battery where, over evolutionary time with a trickle-charge of photosynthesis using solar energy, billions of tons of living biomass were stored in forests and other ecosystems and in vast reserves of fossil fuels. In just the last few hundred years, humans extracted exploitable energy from these living and fossilized biomass fuels to build the modern industrial-technological-informational economy, to grow our population to more than 7 billion, and to transform the biogeochemical cycles and biodiversity of the earth. This rapid discharge of the earth’s store of organic energy fuels the human domination of the biosphere, including conversion of natural habitats to agricultural fields and the resulting loss of native species, emission of carbon dioxide and the resulting climate and sea level change, and use of supplemental nuclear, hydro, wind, and solar energy sources. The laws of thermodynamics governing the trickle-charge and rapid discharge of the earth’s battery are universal and absolute; the earth is only temporarily poised a quantifiable distance from the thermodynamic equilibrium of outer space. Although this distance from equilibrium is comprised of all energy types, most critical for humans is the store of living biomass. With the rapid depletion of this chemical energy, the earth is shifting back toward the inhospitable equilibrium of outer space with fundamental ramifications for the biosphere and humanity. Because there is no substitute or replacement energy for living biomass, the remaining distance from equilibrium that will be required to support human life is unknown.

Pricing carbon: California’s unfinished climate priority

Pricing carbon: California’s unfinished climate priority | Sustain Our Earth | Scoop.it
At the close of their legislative session in August, California lawmakers passed one of the world’s most significant climate policies—SB 32, named after the state’s original climate law from a decade earlier, AB 32. The new bill added a single line to its predecessor, requiring the state to reduce its greenhouse gas emissions 40 percent below 1990 levels by 2030. With that single stroke, California began a new chapter in the story of its formidable climate leadership.
