Shale Gas Debate-UK widget added to my pages. NB. CO2 sequestration and use as a raw material in innovative materials

The struggle control and reduce  ever increasing CO2 gas (and all major green house gases)  is far from over.

Many thanks to The Insitute, IOM3 -Materials World (MW) prompted by their page,"members letters" in particular to F. Glasser and his team at Aberdeen Uni.,Scotland for their work in the "Extraction of CO2 like Sulphur") and CO2 capture in cement and concrete.

Cf. REF's as follows:

2. F.P.Glasser et al. Magnesium based cements for CO2 Capture and Utilisation. Cement and Concrete Research.

Capture and sequestering of CO2 -carbon dioxide-otherwise liberated to the atmosphere, is it appears, a minimum requirement in any shale gas extration project. Better, I guess, is the use of CO2 as a raw material to include in innovative materials products. This would certainly help responsible exploitation of such mineral reserves as Coal and Shale.

 It is also imperative that coal exploitation, coal burning for power generation must be orientated (urgently) in a similar direction ie in the direction of CO2 sequestration and in the CO2 incorporation in materials to provide new and innovative products.

Fredrik Glasser FIMMM, FRSE replies to a IOM3 member's question "Can we capture CO2 like sulphur." His response is brief "YES WE CAN",

"But the the road to market is not straight forward.

"The intense conservatism of the building industry is an important hold point,  so too is the obsession of UK policy with underground storage of liquid CO2 largely to the exclusion of other routes that might deliver positive economic value This policy is neither cheap nor assured and will require massive capital investment investment and ongoing subsidy." [NB. as mentioned Prof Glasser is based in Aberdeen, Scotland the capital (and capital intensive) of UK's fossil energy, North Sea Gas."

 My Comment :Glasser's remarks on policy are of particular importance. Considering CO2 as a raw material in the sustainable economic sense to innovate production of new and improved products and processes could possibly stimulate a more diverse and lively economic playing field as opposed to (or at least complimentary to) the "brushing the dirt under the carpet,  Capturing and sequestration, building prisons approach.

ALSO
Huge reserves are still available and exploited in several nearby countries, eg. Germany and even moreso Poland in our EU. cf . MW on the huge still unexploited Polish coal reserves

But, could Poland have seen the light?


"Prof. Lewiński's group has shown that appropriately designed precursor compounds in reaction with carbon dioxide lead to fabrication of a microporous material (with pore diameters below 2 nm) resulting from self-assembly of luminescent nanoclusters. Novel microporous material, composed of building blocks with zinc carbonate core encapsulated in appropriately designed organic shell (hydroxyquinoline ligands), is highly luminescent, with photoluminescence quantum yield significantly higher than those of classical fluorescent compounds used in state-of-the-art OLEDs."

"The emissions paradox

Compared to other building materials concrete has a low carbon footprint, i.e. it emits less CO2 per tonne. And yet, the enormous volumes used mean that concrete production accounts for about 3 - 8 percent of the man-made CO2 emissions worldwide.

Comparative relative energy and CO2 per construction material

However, given the very large volumes, total emissions are considerable. Because a small reduction in emission can make a real difference, our team of researchers can punch well above their weight and lay the basis for a global reduction of millions of tonnes of CO2 annually." cf Source:nanocem.org/cement-concrete/sustainability-emissions

AND from "The concrete solution, IOM3 Conference News MW June 2015 

 More  facts: 

Standard concrete mix releases up to 79.7kg of CO2 per tonne cf. nanocem value of 0.13 kgCO2/kg concrete. ie. 130kgCO2/tonne roughly 1.6x nanocem's figure. PARADOX indeed must find the reason for this 

By 2020 concrete’s embodied CO2 is estimated to reduce to 71.8kg per tonne of concrete

Sustainability science: Exploiting the synergies

David Griggs, professor of sustainable development at Monash University in Melbourne, Australia, and the University of Warwick, UK. reviews in Nature, Economist Jeffrey D. Sachs book

The Age of Sustainable Development

 Columbia Univ. Press: 2015.ISBN: 9780231173148
Here I shall quote a couple of  quotes which I can easily relate to from Griggs review:
"As a concept and practice, sustainable development emerged on the global scene in 1972, with the United Nations Conference on the Human Environment. Four decades on, in the year that the United Nations is due to set its Sustainable Development Goals (SDGs), the idea remains fuzzy around the edges. Jeffrey Sachs's The Age of Sustainable Development sharpens our understanding. It is, in my view, the best, most comprehensive and most articulate exposition of sustainable development ever written."

Economic and Social factors are underlined:

ECONOMIC:

"Sustainable development was once considered a problem of developing countries, solvable through, and almost as a by-product of, economic growth. But no country has pulled itself out of poverty without fossil fuels, whose emissions drive climate change and pollution, or nitrogen-based fertilizers, which promote algal blooms. And richer countries have demonstrated the problems of uncontrolled development of land and resources, a factor in biodiversity loss. Sustainable development is crucial for all countries, so the SDGs will apply to every nation."

SOCIAL

"How to achieve a sustainable future? Education, Sachs notes, is a lynchpin. When girls stay in school for longer, fertility rates drop. Households with fewer children invest more in education, health and nutrition. He quotes Scottish economist Adam Smith, who wrote in The Wealth of Nations (1776) that because society benefits when people are educated, the costs should be “defrayed by the general contribution of the whole society”. That we have not achieved this more than two centuries later is a baffling and damning indictment."  Blogger's note(Although the Scots are known for their legendary frugality many may take a book from the bicycle Dutch population. Granted Holland is a flat country.

SCIENTIFICALY MEASURED FACTS:

"Alongside the social challenges are climate change, ocean acidification and the current mass extinction of species — serious threats to humanity's capacity to thrive or even survive. For example, the concentration of carbon dioxide in the atmosphere is rising by more than 2 parts per million each year. Sachs concludes that no country is currently on a path to sustainable development."

HOLISTIC NATURE OF THESE PROBLEMS. 

"What becomes clear is that understanding the links between these issues is essential. Along with development aims such as sanitation and health care for a growing and ageing population, there are environmental challenges such as mitigating climate change."

Renewables key in race against climate change clock by Phys.Org's M.Hood.

"Any plausible game plan for capping the rise of Earth's surface temperature depends on replacing fossil fuels with energy sources that generate little or no carbon pollution." writes Marlowe Hood in Phys Org November 1, 2015.


India's commitment on RHS-->>
so please read on...

Hood quoting reliable sources continues:

"That means renewables, especially solar and wind, both of which face fewer constraints to growth than more established clean energy: a river can be dammed only so many times, and nuclear remains expensive and controversial.

But humanity has dithered for so long in the fight against global warming, experts say, that the window of opportunity for decarbonising the global economy fast enough to avoid devastating climate change is barely ajar.

"The cost and difficulty of mitigating greenhouse gases increases every year, time is of the essence," Maria van der Hoeven, executive director of the International Energy Agency, said in a special IEA report on energy and climate change released earlier this year.

The world's nations -– gathering in Paris in a month to ink the first-ever universal climate pact—have set a target of limiting global warming to two degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.

Cross that red line, scientists say, and there will, almost literally, be hell to pay.

Science also tells us that, if we are to respect the 2 C limit, future greenhouse gas emissions cannot exceed a total "budget" of about 1,000 billion tonnes of carbon dioxide.

Carbon-cutting pledges from nearly 150 nations, unveiled on Friday, put us on track for a 3 C world.

This is a vast improvement on doing nothing. But even this unprecedented effort would use up three quarters of that carbon budget by 2030, leaving very little margin for closing the remaining gap. That's where the transition from fossil fuels to renewables comes in

President Obama is quoted as follows "Energy production accounts for two-thirds of global greenhouse gas emissions, and thus transformation of this sector is crucial", he and other experts said.
OTHER IMPORTANT SOURCES QUOTED:
"According to the UN climate science body, the Intergovernmental Panel on Climate Change (IPCC), low-carbon energy must account for at least 80 percent of global electricity production by 2050 to have a better-than-even chance of staying under the 2 C threshold".

"Decarbonising energy is probably the quickest way to decarbonise the world," Adnan Amin, director general of the International Renewable Energies Agency.

The good news is that renewables are expanding rapidly and attracting investment.

Nearly half of all new installed power generation capacity in 2014 was in renewables—37 percent wind, a third solar and a quarter hydro, according to the IEA.

Investment in the sector totalled more than a quarter of a trillion dollars in the same year, an 8.5 percent increase over 2013.

"Capital markets have already begun to shift away from dirty technology to clean technology," Christina Figueres, executive secretary of the UN Framework Convention on Climate Change, told journalists Friday in releasing an analysis of national emissions-reduction pledges.

ENDNOTE:

But renewables only account for about 20 percent of global electricity generation, and three-quarters of that is hydro. Of total energy consumption -– overwhelmingly dominated by coal, oil and gas –- less than five percent comes from clean technology, excluding nuclear.

The transition towards a low-carbon economy is also hampered by fossil fuel subsidies totalling more than half-a-trillion dollars every year, four times the amount allocated for renewables.

Experts say, the Paris climate summit, which starts at the end of this month, is so crucial.

"COP21" -– the Paris climate summit -–STILL "needs to give a global and long-term signal to the world economy that is relevant to investors," said Martin Kaiser, a climate analyst from Greenpeace.

Link_Wind power in Scotland - environment - From The New Scientist motivated arguably by "The Scots Independent Spirit and Renewable Energy Ambitions"

"Scotland is arguably one of the greenest countries in Europe.(notice the nuance) It produces 40 per cent of Scottish electricity demand from renewable sources, and models suggest this could rise to 67 per cent by 2018. That's closing in on the government's goal of producing enough green power to supply the equivalent of all of Scottish demand by 2020.
