energy climate shipping pollution globalization wind

  • Global shipping firms under pressure to cut carbon emissions are experimenting with an age-old technology: sails to harness ocean winds and reduce reliance on costly fuels.
  • picked by European rocket-maker Ariane Group for a sail-equipped cargo ship to transport parts for its new Ariane 6 launcher to French Guiana starting in 2022.The ship will be equipped with four huge rectangular sails rising 30 metres (100 feet) high, supplementing a motor and cutting fuel consumption by about 30 percent.
  • “Our 136-metre ship costs 30% more than current ships,” Zanuttini said, “but we compensate by using 80 to 90% less fuel.”Wind-powered vessels are also slower — a hard sell for some shipowners and clients who want their raw materials and merchandise to move as quick as possible.

  • Operators of the 60 000 to 90 000 oil tankers, bulk carriers, ferries and other huge cargo ships plying the seas are racing to find alternatives to fuel oil as pollution rules are tightened. The industry generates roughly three percent of Earth-warming greenhouse gas emissions worldwide, a figure that experts say could reach 17% by 2050 if nothing is done.
  • starting January 1, levels of air-polluting sulphur in marine fuel must be below 0.5 percent, according to new International Maritime Organisation standards — a sharp drop from today’s 3.5%
  • Beside sails, some firms have designed huge kites that pull cargo ships, though just a few operators have adopted the system.
  • Another option is to use “Flettner rotors” like those built by Norsepower of Finland, employing a technology developed by German engineers in the 1920s.The tall columns are installed on a ship and set spinning, creating lift that propels a ship forward when they catch a perpendicular wind.
  • wind advocates say tighter pollution rules — potentially including more widespread taxes on carbon emissions — will force shipping firms to clean up their act

Murano glass factories forced to shut down furnaces during Europe's gas crisis - The Wa... - 0 views

Italy art industry environment energy trade competition gas

  • In a typical year, the glass factories here power down only once, for maintenance in August. But with Europe in the midst of an energy crisis, facing a 400 percent increase in natural gas bills, the gas-fueled blazes needed to produce Murano’s richly colored, ornate creations have become a luxury the glassmakers can scarcely afford.
  • The gas crisis stems from a combination of factors — insufficient stockpiles within Europe, constrained supply from Russia and increased competition from Asia for access to liquid natural gas. And with the Kremlin threatening to cut off flows if it is hit with sanctions over Ukraine, the crisis could get worse.
  • For Murano’s glassmakers, who were already reeling from a pandemic lockdown in 2020 and massive flooding in 2019, support has come in the form of regional and national subsidies intended to help them get through the winter. But with gas prices continuing to rise, the subsidies aren’t expected to last them beyond next month, tops. That’s led companies like Effetre to keep their furnaces off — and some to consider closing up shop for good.

  • In the eight centuries of Murano glassmaking, the use of natural gas is relatively new, adopted only in the 1950s.
  • But environmental regulations adopted in the interim prevent going back to wood. Local emissions would far exceed the legal threshold, explained Francesco Gonella, a physicist who specializes in artistic glass. “You may have a wood-powered stove up on a mountain, but you can’t have hundreds of wood-powered furnaces going at 1100 degrees Celsius,”
  • “we’ll need a massive investment in local renewable technologies that won’t require the massive costs of importing power from the outside. Geothermic, absolutely, all around the island, and on it. Wind farms, off the lagoon, catching wind at dawn and dusk. And solar. All of these factories also need to be covered in solar panels.”
  • The range and depth of those colors, along with the level of artistry, help authentic Murano glass stand out from mass-produced versions from China.
  • “Murano’s is an unlucky sector,” said Gonella, the physicist. “It finds itself dealing with problems of different natures: commercial, because China rolls out counterfeit glass; environmental; and now the blow delivered by bills that are unsustainable for many.”
  • Electric furnaces can’t provide the kind of heat or artistic control they need. The sector has been looking into hydrogen as an alternative fuel. But that would require building a whole new network of pipes, designed to withstand corrosion from the hydrogen running through them.
  • The glassmaking industry is responsible for only a tiny fraction of Italy’s emissions. But the work is energy-intensive. In a normal year, the Murano factories guzzle more than 13 million cubic meters of natural gas, according to a market insider speaking on the condition of anonymity because he wasn’t authorized by his company to talk. That’s as much as a town of 30,000 people would typically use in domestic heating. Yet Murano is an island of 5,000.
  • Mattia Rossi, 43, shuttered his family business this month because of financial problems made worse by skyrocketing bills.“If I’m shelling out 5,000 euros for the electric bill one month and 15 [thousand] the next, I won’t be able to raise the price by 30 to 40 percent. My goblet would no longer cost 80, but 150 euros. People just won’t buy it then. Because glass is a beautiful thing, but it’s not bread and milk. It’s unnecessary.”

mediterranean gas energy regionalism exports pipelines Egypt Israel Turkey Lebanon Syria Cyprus Russia EU

  • a forum joining Israel, Egypt, Cyprus, and other neighbors to develop their new natural gas discoveries. The Eastern Mediterranean Gas Forum, announced Monday in Cairo, formalizes growing energy ties among recent rivals and could spur much-needed development of energy infrastructure required to tap the region’s potential as a source of energy for Europe and beyond. The forum in particular cements the growing commercial links between Israel and Egypt; Israel expects to start shipping natural gas to Egypt in the next few months as part of a landmark, $15 billion deal between the two countries.
  • a few notable absences, including Syria and Lebanon—both of which are trying to develop potential offshore gas fields—and especially Turkey
  • The new body will promote “discussions among countries that already have cooperation with each other,” said Brenda Shaffer, an energy expert at Georgetown University. “Hopefully, in the next round of the forum, Turkey will be involved, and that would make it much more significant and not just include the happy campers.”

  • Another option to market the gas would be to build liquefied natural gas (LNG) terminals; liquefied gas can be shipped on tankers around the world. But the problem, aside from the upfront cost of building the expensive infrastructure needed to superchill natural gas, is the economics of the gas trade, especially when it comes to competing with Russian energy supplies to Europe. LNG costs a lot more than natural gas shipped through a pipeline, and Russian gas is especially cheap.
  • grandiose plans, such as a pipeline snaking across to southern Europe via Crete, keep colliding with political and economic realities. Deep waters and high costs make building a pipeline to Europe an expensive proposition
  • even with the creation of the new organization and increased energy exploration, the Eastern Mediterranean has a long way to go to truly become the kind of energy hub that many in the region and even in Brussels hope to see. The European Union’s top energy official, for instance, has repeatedly pointed to the Eastern Mediterranean’s potential as an alternative source of energy to importing gas from Russia, and Egypt dreams of again becoming an exporter of natural gas to Europe, as it was until 2012
  • Europe’s dependence on Russian energy is growing,
  • Tapping its own natural gas fields would enable Cyprus to replace costly energy imports and power its economy. Israel has already turned its first offshore gas discoveries into a new, cleaner source of electricity, and the country hopes to phase out coal entirely over the next decade. Egypt, too, is using domestic natural gas resources to keep the lights on and factories running, and natural gas demand there is expected to keep growing and potentially gobble up whatever is produced by additional offshore discoveries.
