Wind Farms Take Root Out at Sea - NYTimes.com - 0 views

  • “If you want to do wind on a big scale with power plants based on wind, you need to go offshore,
  • Wind farms are no longer engineering experiments or small pilot schemes. They have grown very large, to the point where they are of the same scale as gas- or coal-fired power stations.
  • Siemens figures there are about 3.3 gigawatts of offshore wind power connected to the grid in Europe. That is similar in size to a large contemporary nuclear power station.

  • but that will depend on many factors, including costs and government support.
  • Offshore wind has advantages beyond the presence of sea breezes. The seabed is relatively cheap real estate, and much larger wind farms can be built there than on land. The vast expanses available at sea allow economies of scale that may bring down costs.
  • The key to cutting costs, Mr. Hannibal said, is to simplify the installation process and turn manufacturing of turbines into a cookie-cutter industrial process. The latest turbines are made of just a few components that are relatively easy to anchor to the sea bottom.
  • Still, costs remain stubbornly high. Mr. Hannibal figures that the power to be produced by new German offshore wind projects will cost 130 to 140 euros, or $175 to $185, per megawatt hour, which is about triple the wholesale power price.

  • ack in 1990, the IPCC relied on just two relatively crude models. Today, the IPCC can take advantage of 45 different models that incorporate a wide range of features of the Earth's climate, from ocean biology to changes in soil. Their accuracy has improved considerably since 1990. But it's unclear if those models can keep improving significantly.
  • And even in its 2007 assessment report, the IPCC could only explain about 60 percent of the rise in sea-level that had already occurred in the previous half-century. Nowadays, however, climate scientists can account for virtually all of the past sea-level rise,

Is Europe's gas supply threatened by the Ukraine crisis? | World news | The Guardian - 0 views

  • Is Europe's gas supply threatened by the Ukraine crisis?
  • more than a quarter of the EU's total gas needs were met by Russian gas, and some 80% of it came via Ukrainian pipelines. Austria, France, Germany, Hungary, Italy and Poland soon reported gas pressure in their own pipelines was down by as much as 30%.
  • While it was eventually resolved through a complex deal that saw Ukraine buying gas from Russia (at full price) and Turkmenistan (at cut price) via a Swiss-registered Gazprom subsidiary
  • ...10 more annotations...
  • But three years later, the same row erupted again: Gazprom demanded a price hike to $400-plus from $250, Kiev flatly refused, and on New Year's day 2009, Gazprom began pumping only enough gas to meet the needs of its customers beyond Ukraine.
  • Again, the consequences were marked. Inevitably, Russia accused Ukraine of siphoning off supplies meant for European customers to meet its own needs, and cut supplies completely
  • several countries – particularly in south-eastern Europe, almost completely dependent on supplies from Ukraine – simply ran out of gas.
  • Bulgaria shut down production in its main industrial plants; Slovakia declared a state of emergency
  • Many industry experts, though, point out that the world has changed since 2009, and that there are any number of reasons why Moscow's natural gas supplies may not prove quite the potent economic and diplomatic weapon they once were.
  • higher than normal temperatures are forecast to continue for several weeks yet, significantly reducing demand for gas and leaving prices at their lowest for two years
  • since the first "gas war" of 2006, many European countries have made huge efforts to increase their gas storage capacity and stocks are high. Some countries, such as Bulgaria, Slovakia and Moldova, which lack large storage capacity and depend heavily on gas supplies via Ukraine, would certainly suffer from any disruption in supplies
  • New Gazprom pipelines via Belarus and the Baltic Sea to Germany (Nord Stream) have cut the proportion of Gazprom's Europe-bound exports that transit via Ukraine to around half the total, meaning only about 15% of Europe's gas now relies on Ukraine's pipelines. Gazprom is also planning a Black Sea pipeline (South Stream), expected in 2015, meaning its exports to Europe will bypass Ukraine completely. Ukraine itself has cut its domestic gas consumption by nearly 40% over the past few years, halving its imports from Russia in the process.
  • Europe is increasingly installing specialist terminals that will allow gas to be imported from countries such as Qatar in the form of liquefied natural gas – while Norway's Statoil sold more gas to European countries in 2012 than Gazprom did. "Since the Russian supply cuts of 2006 and 2009, the tables have totally turned," Anders åslund, an energy advisor to both the Russian and Ukrainian governments, told the Washington Post.
  • Europe accounts for around a third of Gazprom's total gas sales, and around half of Russia's total budget revenue comes from oil and gas. Moscow needs that source of revenue, and whatever Vladimir Putin's geo-political ambitions, most energy analysts seem to agree he will think twice about jeopardising it.

Reinventing the European Dream by Anne-Marie Slaughter - Project Syndicate - 0 views

  • Natural-gas fields in the Eastern Mediterranean are estimated to hold up to 122 trillion cubic feet, enough to supply the entire world for a year. More gas and large oil fields lie off the Greek coast in the Aegean and Ionian Seas, enough to transform the finances of Greece and the entire region. Israel and Cyprus are planning joint exploration; Israel and Greece are discussing a pipeline; Turkey and Lebanon are prospecting; and Egypt is planning to license exploration.
  • But politics, as always, intervenes. All countries involved have maritime disputes and political disagreements. The Turks are working with Northern Cyprus, whose independence only they recognize, and regularly make threatening noises about Israel’s drilling with the Greek Cypriot government of the Republic of Cyprus. The Greek Cypriots regularly hold the EU hostage over any dealings with Turkey, as has Greece. The Turks will not let Cypriot ships into their harbors and have not been on speaking terms with the Israelis since nine Turkish citizens were killed on a ship that sought to breach Israel’s blockade of Gaza. Lebanon and Israel do not have diplomatic relations.

Oil tanker - Wikipedia, the free encyclopedia - 0 views

  • Oil tankers are often classified by their size as well as their occupation. The size classes range from inland or coastal tankers of a few thousand metric tons of deadweight (DWT) to the mammoth ultra large crude carriers (ULCCs) of 550,000 DWT.
  • The expense was significant: for example, in the early years of the Russian oil industry, barrels accounted for half the cost of petroleum production.[10]
  • While a typical T2 tanker of the World War II era was 532 feet (162 m) long and had a capacity of 16,500 DWT, the ultra-large crude carriers (ULCC) built in the 1970s were over 1,300 feet (400 m) long and had a capacity of 500,000 DWT.[29]
  • ...3 more annotations...
  • "Supertankers" are the largest tankers, including very large crude carriers (VLCC) and ULCCs with capacities over 250,000 DWT. These ships can transport 2,000,000 barrels (320,000 m3) of oil/318 000 metric tons.[46] By way of comparison, the United Kingdom consumed about 1.6 million barrels (250,000 m3) of oil per day in 2009.[47] ULCCs, commissioned in the 1970s, were the largest vessels ever built, but the longest ones have already been scrapped; only a few ULCCs remain in service, none of which are more than 400m long.[48] Because of their great size, supertankers often can not enter port fully loaded.[28] These ships can take on their cargo at off-shore platforms and single-point moorings.[28] On the other end of the journey, they often pump their cargo off to smaller tankers at designated lightering points off-coast.[28] A supertanker's routes are generally long, requiring it to stay at sea for extended periods, up to and beyond seventy days at a time.[28]
  • As demand grew moderately in the United States and Western Europe, expanding economies such as China fueled exponential growth in demand.[60]
  • The average one-year time charter rate for a 5-year-old tanker of 280,000 metric tons of deadweight varied from $56,500 per day in December 2005 to $53,000 per day in September 2007 with a high of $64,500 per day in September 2006.[59]

Deepening divide over Elbe dredging | Germany | DW.COM | 19.12.2016 - 0 views

  • Deepening divide over Elbe dredging
  • The Marco Polo, for example, carries 16,000 containers and has a draft (the vertical distance between waterline and ship's keel) of 16 meters. Given present river depths and tides, such ships can only enter Hamburg at certain times and when not fully loaded.
  • Tidal range is a prime cause for erosion, which previous river dredging, as well as waves generated by passing ships, have exacerbated
  • ...2 more annotations...
  • As the river deepens, more seawater from the North Sea flows at a faster rate towards Hamburg, bringing sediment that builds up on the riverbed. The Hamburg Port Authority dredges the river to counteract the build up, which cost taxpayers 120 million euros ($125 million) in 2015.
  • The two projects amount to an expensive redundancy, Siegert said, with the JadeWeserPort costing $1.6 billion and the Elbe project an additional $940 million. "This is the reason for our protest: They decided on the first port, and now they should coordinate traffic, so that the really large ships can go to Wilhelmshaven or, under certain restrictions, to Hamburg."

Europe Haggles Over New Rules Aimed at Saving Fish Stocks - WSJ.com - 0 views

  • Fishermen currently discard nearly a quarter of Europe's total catch on average, and as much as 70% of the hauls in some areas, European Commission data show
  • "The law has been made by someone who doesn't know fisheries," said fisherman Geert Luickx as he painted his boat here in this North Sea port. Without financial assistance, more crew, and a bigger boat, he said, he won't be able to comply with the new law.

What If We Never Run Out of Oil? - Charles C. Mann - The Atlantic - 0 views

  • In most cases, mining tar sands involves drilling two horizontal wells, one above the other, into the bitumen layer; injecting massive gouts of high-pressure steam and solvents into the top well, liquefying the bitumen; sucking up the melted bitumen as it drips into the sand around the lower well; and then refining the bitumen into “synthetic crude oil.”
  • Economists sometimes describe a fuel in terms of its energy return on energy invested (EROEI), a measure of how much energy must be used up to acquire, process, and deliver the fuel in a useful form. OPEC oil, for example, is typically estimated to have an EROEI of 12 to 18, which means that 12 to 18 barrels of oil are produced at the wellhead for every barrel of oil consumed during their production. In this calculation, tar sands look awful: they have an EROEI of 4 to 7. (Steaming out the bitumen also requires a lot of water. Environmentalists ask, with some justification, where it all is going to come from.)
  • To obtain shale gas, companies first dig wells that reach down thousands of feet. Then, with the absurd agility of anime characters, the drills wriggle sideways to bore thousands of feet more through methane-bearing shale. Once in place, the well injects high-pressure water into the stone, creating hairline cracks. The water is mixed with chemicals and “proppant,” particles of sand or ceramic that help keep the cracks open once they have formed. Gas trapped between layers of shale seeps past the proppant and rises through the well to be collected.

  • Several researchers told me that the current towel-snapping between Beijing and Tokyo over islands in the East China Sea is due less to nationalistic posturing than to nearby petroleum deposits.)
  • Today, a fifth of U.S. energy consumption is fueled by coal, mainly from Appalachia and the West, a long-term energy source that has provided jobs for millions, a century-old way of life
  • and pollution that kills more than 10,000 Americans a year (that estimate is from a 2010 National Research Council study).
  • Roughly speaking, burning coal produces twice as much carbon dioxide as burning the equivalent amount of natural gas. Almost all domestic coal is used to generate electricity—it produces 38 percent of the U.S. power supply. Fracking is swiftly changing this: in 2011, utilities reported plans to shut down 57 of the nation’s 1,287 coal-fired generators the following year. Largely in consequence, U.S. energy-related carbon-dioxide emissions have dropped to figures last seen in 1995. Since 2006, they have fallen more than those from any other nation in the world.
  • In the sort of development that irresistibly attracts descriptors like ironic, Germany, often touted as an environmental model for its commitment to solar and wind power, has expanded its use of coal, and as a result is steadily increasing its carbon-dioxide output. Unlike Americans, Europeans can’t readily switch to natural gas; Continental nations, which import most of their natural gas, agreed to long-term contracts that tie its price to the price of oil, now quite high.
  • Water-assisted fracturing has been in use since the late 1940s, but it became “fracking” only recently, when it was married with horizontal drilling and the advanced sensing techniques that let it be used deep underground. Energy costs are surprisingly small; a Swiss-American research team calculated in 2011 that the average EROEI for fracked gas in a representative Pennsylvania county was about 87—about six times better than for Persian Gulf oil and 16 times better than for tar sands. (Fracking uses a lot of water, though, and activists charge that the chemicals contaminate underground water supplies.)
  • In mid-March, Japan’s Chikyu test ended a week early, after sand got in the well mechanism. But by then the researchers had already retrieved about 4 million cubic feet of natural gas from methane hydrate, at double the expected rate.
  • What is known, says Timothy Collett, the energy-research director for the USGS program, is that some of the gulf’s more than 3,500 oil and gas wells are in gas-hydrate areas.
  • In Dutch-disease scenarios, oil weakens all the pillars but one—the petroleum industry, which bloats steroidally.
  • Because the national petroleum company, with its gush of oil revenues, is the center of national economic power, “the ruler typically puts a loyalist in charge,” says Michael Ross, a UCLA political scientist and the author of The Oil Curse (2012). “The possibilities for corruption are endless.” Governments dip into the oil kitty to reward friends and buy off enemies. Sometimes the money goes to simple bribes; in the early 1990s, hundreds of millions of euros from France’s state oil company, Elf Aquitaine, lined the pockets of businessmen and politicians at home and abroad.
  • How much of Venezuela’s oil wealth Hugo Chávez hijacked for his own political purposes is unknown, because his government stopped publishing the relevant income and expenditure figures. Similarly, Ross points out, Saddam Hussein allocated more than half the government’s funds to the Iraq National Oil Company; nobody has any idea what happened to the stash, though, because INOC never released a budget. (Saddam personally directed the nationalization of Iraqi oil in 1972, then leveraged his control of petroleum revenues to seize power from his rivals.)
  • “How will the royal family contain both the mullahs and the unemployed youth without a slush fund?”
  • It seems fair to say that if autocrats in these places were toppled, most Americans would not mourn. But it seems equally fair to say that they would not necessarily be enthusiastic about their replacements.

Russia Steps Up Economic Pressure on Kiev - NYTimes.com - 0 views

  • Russia Steps Up Economic Pressure on Kiev
  • Russia is now asking close to $500 for 1,000 cubic meters of gas, the standard unit for gas trade in Europe, which is a price about a third higher than what Russia’s gas company, Gazprom, charges clients elsewhere. Russia says the increase is justified because it seized control of the Crimean Peninsula, where its Black Sea naval fleet is stationed, ending the need to pay rent for the Sevastopol base. The base rent had been paid in the form of a $100 per 1,000 cubic meter discount on natural gas for Ukraine’s national energy company, Naftogaz.
  • Mr. Yatsenyuk raised the pressing need to build an interconnector pipe allowing for a so-called reverse flow from the European Union into the Ukrainian gas system. “We need reverse flows of gas from the European Union to support Ukraine’s energy security,” Mr. Yatsenyuk said.
  • ...2 more annotations...
  • For years, Gazprom offered successive Ukrainian governments what it called discounts on the fuel, only to continue charging Naftogaz more than other European utilities.
  • Even with the rent for the Sevastopol naval base deducted from the price of gas, Gazprom had charged Naftogaz $395 to $410 for every 1,000 cubic meters of natural gas, for most of 2013. By comparison, Gazprom’s average price in Western Europe for the first nine months of last year was $380 for the same volume.

U.S. Offshore Wind Farm, Made in Europe - NYTimes.com - 0 views

  • On Germany’s coast, for example, an estimated $1.3 billion went into revitalizing ports and factories to serve the industry, creating about 10,000 jobs. But demand frequently drops off when projects stall, at times leaving factories in coastal towns like Cuxhaven, on Germany’s North Sea, sitting idle with hundreds of workers laid off.
  • But a major setback came around 2009, when G.E. decided to back away from the offshore wind business, saying it was still too expensive to compete with land-based wind power.

Russia Presses Ahead With Plan for Gas Pipeline to Turkey - NYTimes.com - 0 views

  • But in recent weeks, the Russian state-owned company Gazprom has shown signs that it is serious about proceeding with what it calls Turkish Stream.
  • Gazprom’s chief executive recently made it clear that Turkey is its new focus — and that if Europe wants more Russian gas then it will need to find its own way to tap into it.
  • ...3 more annotations...
  • Another potential sticking point is Turkey itself. For one thing, the country obtains about 60 percent of its gas from Russia, a dependence the government is not necessarily eager to increase.
  • Industry analysts estimate that the cost of Turkish Stream would be about $10 billion for Gazprom, which so far has spent an estimated $4.7 billion on the Black Sea project.
  • Mr. Putin already publicly offered a 6 percent reduction to Turkey. But Ankara, which pays substantially more for Russian gas than Germany does, is pressing for a better deal.

As Panama Canal Expands, West Coast Ports Scramble to Keep Big Cargo Vessels - NYTimes.com - 0 views

  • Making Everything Shipshape
  • The ports in Tacoma, Seattle, Oakland, Los Angeles, Long Beach and elsewhere offer much shorter sailing times than Gulf Coast and East Coast ports. But for shippers of some goods, the web of logistics, including trucks and railroads, ends up being less expensive if they go through the Panama Canal.
  • While the widened Panama Canal will allow an all-water route for big ships to the East Coast, the project — originally scheduled to open this year — has been plagued with construction delays. And the authorities have yet to announce toll charges for passing ships. In the end, it might be too expensive for some ships to use.

  • At the same time, sailing patterns may shift as Asian manufacturing continues to move from China to countries to the south, like Singapore and Vietnam, which are actually closer by sea to East Coast ports through the Suez Canal than to West Coast ports across the Pacific.
  • For trade with China, Prince Rupert’s appeal is proximity. Prince Rupert is two to three days closer than the western coast of the United States, helping ships cut fuel costs.
  • While the railways and truck lines in Canada have a history of labor instability, cargo carriers sailing into the country can avoid taxes levied by the United States government.

Gazprom Cuts Russia's Natural Gas Supply to Ukraine - NYTimes.com - 0 views

  • The gas flowing into Ukraine as of Monday was meant only to transit the country to Europe. “Gazprom supplies to Ukraine only the amount that has been paid for, and the amount that has been paid for is zero,” Gazprom’s spokesman, Sergei Kupriyanov, told reporters.
  • Gazprom, which has sought for the past decade to convince the Europeans that it is a reliable supplier and not an arm of Russian foreign policy, painted the dispute as strictly commercial.
  • Second, Gazprom has provoked economic ire in Europe over its plans to build an alternative gas route under the Black Sea for the company’s exclusive use, contradicting Europe’s open access laws. That has put the future of what is known as the South Stream pipeline in doubt.
  • ...1 more annotation...
  • About a fifth of the European Union’s supply of natural gas flows through Ukraine. Ukraine itself imported from Russia 63 percent of the natural gas it consumed in 2012, producing the remaining 37 percent domestically, according to the United States Energy Information Agency.
