*****Frontier hydrocarbons: China makes 'flammable ice' breakthrough in South China Sea - May. 19, 2017

China's minister of land and resources, Jiang Daming, said Thursday that the successful collection of the frozen fuel was "a major breakthrough that may lead to a global energy revolution," according to state media. Experts agree that flammable ice could be a game changer for the energy industry, similar to the U.S. shale boom. But they caution that big barriers -- both technological and environmental -- need to be cleared to build an industry around the frozen fuel, which is also known as gas hydrate.

Nearly a century ago, British scientist JB Haldane saw an energy future in which wind power would be used to generate hydrogen; a fuel he described as, weight-for-weight, the most efficient known method of storing energy.

*****How Australia can use hydrogen to export its solar power around the world

He thought this future was four hundred years away, but the so-called “hydrogen economy” may arrive a lot sooner thanks to a recent burst of innovations in hydrogen generation, storage, transport and use. And it could open a new energy export market for Australia. Hydrogen itself isn’t actually a fuel – it’s an energy carrier. The gas is produced by splitting water molecules into hydrogen and oxygen by the electricity-driven process electrolysis.

That hydrogen is then condensed under pressure and at very low temperatures into a liquid, which can be used in much the same way as petrol and diesel, or it can be used in fuel cells to generate electricity. Hydrogen’s greatest asset is its potential to be the ultimate source of clean energy. *****#Map shows how dependent European countries are on #gas from #Russia. #Renewables are a #geopolitical asset too!

*****UK launches ‘world first’ research programme into negative emissions

NETs will “almost certainly be needed” to reach the goals of the Paris Agreement on climate change, one of the researchers tells Carbon Brief. Yet there is huge uncertainty over whether it will be possible to deploy them quickly – and at scale – without causing knock-on environmental and social problems. The new research programme is designed to investigate their potential, as well as the political, social and environmental issues surrounding their deployment. It is coordinated by the UK’s government-funded National Environment Research Council (NERC). Carbon Brief has the details. Paris goals Most of them agreed it was highly unlikely to be possible.

*****First coal-free day in Britain since Industrial Revolution

The energy provider said Friday's lack of coal usage was a "watershed" moment. Britain's longest continuous energy period without coal until now was 19 hours - first achieved last May, and again on Thursday. The government plans to phase out Britain's last plants by 2025 in order to cut carbon emissions.

Friday is thought to be the first time the nation has not used coal to generate electricity since the world's first centralised public coal-fired generator opened in 1882, at Holborn Viaduct in London. Today saw 24 hrs of no coal. Last week saw 73% of power from low carbon sources.

James Bond and other movie heroes often take us to within seconds of armageddon before choosing the correct wire to snip or delicately removing the trigger from the latest doomsday device. Now, Christiana Figueres, the former Executive Secretary of the United Nations Framework Convention on Climate Change, is using Hollywood’s technique of narrow escapes for the launch of her latest crusade to save the world from the ravages of uncontrolled climate change.

Using #2020DontBeLate, the campaign pinpoints 2020 as the ‘climate turning point’, the last moment at which we can still roll back the clock and reverse the effects human activity has already had on our planet’s climate.

*****Renewables' deep-sea mining conundrum

Their investigation of a seamount more than 500km (300 miles) from the Canary Islands has revealed a crust of "astonishingly rich" rock. Samples brought back to the surface contain the scarce substance tellurium in concentrations 50,000 times higher than in deposits on land. Tellurium is used in a type of advanced solar panel, so the discovery raises a difficult question about whether the push for renewable energy may encourage mining of the seabed. *****Ireland is set to be the first nation to completely cut investment in fossil fuels #climate.

*****Invasive species / Alien species: Life on Earth is getting a major redistribution, and the consequences are serious. Last year in Paris, for the very first time, English sparkling wine beat champagne in a blind tasting event. Well established French Champagne houses have started buying fields in Britain to grow grapes, and even the royal family is investing in this new venture. At the same time, coffee-growing regions are shrinking and shifting. Farmers are being forced to move to higher altitudes, as the band in which to grow tasty coffee moves up the mountain. The evidence that climate change is affecting some of our most prized beverages is simply too great to be ignored. So while British sparkling wine and the beginning of the “coffeepocalypse” were inconceivable just a few decades ago, they are now a reality. Dramatic examples of climate-mediated change to species distributions are not exceptions; they are fast becoming the rule. These changes are already having serious consequences for economic development, livelihoods, food security, human health, and culture.

Back-to-back severe bleaching events have affected two-thirds of Australia’s Great Barrier Reef, new aerial surveys have found. The findings have caused alarm among scientists, who say the proximity of the 2016 and 2017 bleaching events is unprecedented for the reef, and will give damaged coral little chance to recover.

Scientists with the Australian Research Council’s Centre of Excellence for Coral Reef Studies last week completed aerial surveys of the world’s largest living structure, scoring bleaching at 800 individual coral reefs across 8,000km. The results show the two consecutive mass bleaching events have affected a 1,500km stretch, leaving only the reef’s southern third unscathed. Where last year’s bleaching was concentrated in the reef’s northern third, the 2017 event spread further south, and was most intense in the middle section of the Great Barrier Reef.

(theconversation)

There are a number of available low-carbon technologies to generate electricity. But are they really better than fossil fuels and nuclear power? To answer that question, one needs to compare not just the emissions of different power sources but also the health benefits and the threats to ecosystems of green energy. Production of electricity is responsible for about a quarter of global greenhouse gas emissions, and demand is poised to rise as underserved populations connect to the grid, and electronics and electric vehicles proliferate. So stopping global warming will require a transformation of electricity production. But it is important to avoid various environmental pitfalls in this transition, such as disrupting ecosystems and wildlife or causing air pollution. *****#Renewableenergy is the major growth story in all of our World Energy Outlook 2016 scenarios by @IEA.
