China-built nuclear reactors may enjoy home advantage as delays and costs stymie foreign competitors

by Bloomberg, April 2, 2019 in SouthChinaMorningPost


China’s home-grown nuclear technology is gaining favour in the battle for the nation’s next generation of reactors, according to a state-owned developer, as it sought to recover from delays and cost blowouts from imported designs.

China’s reactor, known as the Hualong One, will be faster and easier to repair and maintain than competing foreign designs because it will be made at home, according to Chen Hua, chief executive officer of China National Nuclear Power company (CNNP), which builds and operates nuclear power projects.

“We prefer the Hualong One,” Chen said on Monday at a nuclear energy conference in Beijing.

The global nuclear industry has been awaiting a revival in China after cost overruns and stricter regulation after the 2011 Fukushima disaster in Japan stalled the approval and construction of more units.

China boosts coal mining capacity despite climate pledges

by M. Xu  & D. Patton, March 26, 2019 in Reuters


BEIJING (Reuters) – China added 194 million tonnes of coal mining capacity in 2018, data from the energy bureau showed on Tuesday, despite vows to eliminate excess capacity in the sector and to reduce fossil fuel consumption.

Total coal mining capacity in the country was at 3.53 billion tonnes per year by the end of 2018, according to a statement from the National Energy Administration (NEA). That compares to 3.34 billion tonnes at the end of 2017.

China Says Massive Shale Oil Reserves Found In North

by Tsvetana Paraskova, March 1, 2019 in OilPrice


China has found massive shale oil reserves in its northern Tianjin municipality, Chinese news agency Xinhua reported on Friday.

Two wells at a field have been flowing for more than 260 days, according to Dagang Oilfield, a subsidiary of state-owned China National Petroleum Corporation (CNPC).

The newly found shale reserves will help boost China’s national energy security and economic development, Xinhua quoted CNPC as saying.

According to EIA estimates, China ranks third in the world in terms of technically recoverable shale oil resources, behind Russia and the United States

CHINA AND THE PAUSE

by GWPF, March 8, 2019


Chinese climate scientists are clearly off-message. They keep referring to the global warming hiatus which so many scientists and activists – those who shout on twitter and prowl the comment sections of off-colour articles on the subject – know has been trounced and discredited again and again. They clearly ought to have a word with the emerging science powerhouse that is China.

Writing recently in “Science of The Total Environment,” Li and Zha of Nanjing Normal University, say the global hiatus has played a prominent role in their thinking and they see it reflected in China. Using satellite data they found a hiatus in China between 2001-15. They found warming in western and southern China and a 15-year cooling trend in northern China. For China as a whole they estimate that the warming rate is just -0.02°C per decade. The conclude that, “there is a regional warming hiatus, a pause or slowdown in China, and (it) implies that greenhouse gas induced warming is suppressed by other natural forcing in the early 21st century.”

There is also Li et al writing in Climate Dynamics who are a little more forceful saying, “since the late 1990s, the global warming has ground to a halt, which has sparked a rising interest among the climate scientists. The hiatus is not only observed in globally average surface air temperature, but also in the China winter air temperature trend, which turns from warming during 1979-1997 to cooling during 1998-2013.” They attribute the effect to the melting of Arctic sea ice.

Gan et al (Lanzhou University and South Dakota State University), reporting in Earth and Space Science say that the hiatus, if not cooling, is seen over the Northern Hemisphere finding that the daily temperature minimum experienced an “obvious” decline in North America during the warming slowdown period. They relate the changes in daily temperature minimum to the Atlantic Multi-decadal Oscillation.

Fracking the World: Despite Climate Risks, Fracking Is Going Global

by Justin Mikulka, March 4, 2019 in Desmog


The U.S. exported a record 3.6 million barrels per day of oil in February. This oil is the result of the American fracking boom — and as a report from Oil Change International recently noted — its continued growth is undermining global efforts to limit climate change. The Energy Information Administration predicts U.S. oil production will increase again in 2019 to record levels, largely driven by fracking in the Permian shale in Texas and New Mexico.

And the U.S. is not alone in trying to maximize oil and gas production. Despite the financial failures of the U.S. fracking industry, international efforts to duplicate the American fracking story are ramping up across the globe.

The CEO of Saudi Arabian state oil company Aramco recently dismissed the idea that global demand for oil will decrease anytime soon and urged the oil industry to “push back on exaggerated theories like peak oil demand.”

But Saudi Aramco also is gearing up for a shopping spree of natural gas assets, including big investments in the U.S., and increasing gas production via fracking in its own shale fields. Aramco is deeply invested in keeping the world hungry for more oil and gas.

Khalid al Falih, Saudi Arabia’s energy minister, told the Financial Times, “Going forward the world is going to be Saudi Aramco’s playground.” But not if other countries frack there first.

China Expanding Fracking Efforts, Testing New Technology

A 119-Year Temperature Reconstruction for the South China Sea

by Y, S., Zheng et al., 2018, Marine Micropaleontology, in CO2Science


According to Yuan et al. (2018), “studies examining sea surface temperature variability over the past one century and their influence on climate change in China are seriously lacking.” And therefore, in an effort to remedy this information void, the team of eight Chinese scientists developed “the first tree-ring-based dendroclimatic sea surface temperature (SST) reconstruction for the South China Sea.”

In accomplishing their objective Yuan et al. cored 22 Pinus massoniana trees in the Changting Region of the Fujian Province, China. Analysis of the cores revealed a statistically significant relationship between the tree-ring series and gridded March SSTs (1°C resolution) of the South China Sea (16-20°N, 112-116°E). Ultimately, this relationship enabled them to produce a proxy temperature reconstruction over the period 1893-2011, which reconstruction is shown below.

China’s coal mine methane regulations have not curbed growing emissions

Abstract

Anthropogenic methane emissions from China are likely greater than in any other country in the world. The largest fraction of China’s anthropogenic emissions is attributable to coal mining, but these emissions may be changing; China enacted a suite of regulations for coal mine methane (CMM) drainage and utilization that came into full effect in 2010. Here, we use methane observations from the GOSAT satellite to evaluate recent trends in total anthropogenic and natural emissions from Asia with a particular focus on China. We find that emissions from China rose by 1.1 ± 0.4 Tg CH4 yr−1 from 2010 to 2015, culminating in total anthropogenic and natural emissions of 61.5 ± 2.7 Tg CH4 in 2015. The observed trend is consistent with pre-2010 trends and is largely attributable to coal mining. These results indicate that China’s CMM regulations have had no discernible impact on the continued increase in Chinese methane emissions.

Is China’s plan to use a nuclear bomb detonator to release shale gas in earthquake-prone Sichuan crazy or brilliant?

by Charles the moderator, January 31, 2019 in WUWT


From The South China Morning Post

  • Scientists have developed an ‘energy rod’ that can fire multiple shock waves to frack sedimentary rock at depths of up to 3.5km

  • China has the world’s largest reserves of natural gas but current mining technology makes most of it inaccessible

China is planning to apply the same technology used to detonate a nuclear bomb over Hiroshima during the second world war to access its massive shale gas reserves in Sichuan province. While success would mean a giant leap forward not only for the industry but also Beijing’s energy self-sufficiency ambitions, some observers are concerned about the potential risk of widespread drilling for the fuel in a region known for its devastating earthquakes.

Despite being home to the largest reserves of shale gas on the planet – about 31.6 trillion cubic metres according to 2015 figures from the US Energy Information Administration, or twice as much as the United States and Australia combined – China is the world’s biggest importer of natural gas, with about 40 per cent of its annual requirement coming from overseas.

THE ROAD FROM PARIS: CHINA’S CLIMATE U-TURN

by Presse Release, GWPF,  December 12, 2018


For all its green talk, China is sticking to fossil fuels

London, 12 December – While leaders of western countries fret about their greenhouse gas emissions in Katowice, China is forging ahead with new projects and investments in coal and gas. According to a new paper from the Global Warming Foundation (GWPF), the Communist Party’s survival depends on delivering economic growth and cleaner air.

China: No Wind Or Solar If It Can’t Beat Coal On Price

by  John Parnell, January 10, 2019 in Forbes


China has said it will not approve wind and solar power projects unless they can compete with coal power prices.

Beijing pulled the plug on support for large solar projects, which had been receiving a per kWh payment, in late May. That news came immediately after the country’s largest solar industry event and caught everyone by surprise.

Officials are understood to have been frustrated at seeing Chinese suppliers and engineering firms building solar projects overseas that delivered electricity at prices far below what was available back home.

Les COP se succèdent, le charbon résiste

by Connaissance des Energies, 18 décembre 2018


Trois jours après la clôture de la COP24, l’Agence internationale de l’énergie (AIE) a publié le 18 décembre son rapport annuel consacré au charbon. Elle y souligne le rôle central de cette énergie au niveau mondial et estime que sa consommation globale devrait rester stable dans les 5 prochaines années. Explications.

La consommation de charbon encore appelée à augmenter en Inde et en Asie du Sud-Est

Après deux années de baisse, la consommation mondiale de charbon a augmenté de près de 1% en 2017 et cette hausse devrait se poursuivre en 2018 selon les dernières estimations de l’AIE. Principalement consommé à des fins de production électrique(1), le charbon a encore compté pour 38% de la production mondiale d’électricité en 2017.

Dans son rapport Coal 2018, l’AIE estime que la consommation mondiale de charbon pourrait rester stable d’ici à 2023 : la baisse de la demande envisagée en Europe et en Amérique du Nord serait plus que compensée par une forte croissance de la consommation en Inde et en Asie du Sud-Est selon les prévisions de l’Agence.

Sea level oscillations in Japan and China since the start of the 20th century and consequences for coastal management – Part 1: Japan Author links open overlay panel

by Albert Parker, March 1, 2019 in Ocean&CoastalManagement


Highlights
• Japan has strong quasi-20 and quasi-60 years low frequencies sea level fluctuations.
• These periodicities translate in specific length requirements of tide gauge records.
• 1894/1906 to present, there is no sea level acceleration in the 5 long-term stations.
• Those not affected by crustal movement (4 of 5) do not even show a rising trend.
Proper consideration of the natural oscillations should inform coastal planning.

China Ignores Paris Climate Accord As CO2 Emissions Rapidly Rise

by Chriss Street, December 31, 2018 in ClimateChange Dispatch


Despite being lauded by President Obama for signing the Paris UN Climate Change Accords, China is still rapidly expanding greenhouse gas emissions.

President Obama and China’s President Xi Jinping issued a ‘U.S.-China Joint Presidential Statement on Climate Change’on March 31, 2016 stating that both nations were signing the Paris Accords and would take further “concrete steps” to “use public resources to finance and encourage the transition toward low carbon technologies as a priority.”
