Aramco is cleanest supplier of oil to China, US research finds

HOUSTON: Saudi Aramco supplies the environmentally cleanest oil to China, the biggest energy consumer in the world, according to a recent scientific study.
A research paper by Nature Energy, a publication of Stanford University in the US, compared the greenhouse gas (GHG) emissions from 13 big oil producers that shipped crude oil to China.
The results showed that Saudi crude had the lowest average carbon intensity when processed and used by Chinese industry, meaning that it produced fewer environmentally harmful emissions than other suppliers.
Venezuela sold China the “dirtiest” oil, according to the study, followed by Iran and Iraq, the researchers found.
Oil industry experts said that the findings reflect not only the higher quality of Saudi crude, but also the efficiency of the technology used to get the crude from reservoirs to shipment.
The study was highlighted at the CERAWeek by IHS Markit event in Houston, Texas. Amin Nasser, chief executive of Saudi Aramco, said: “Not all crudes are equal, and (the research shows that) Saudi Arabia has among the lowest carbon intensities of crude production in the world.”
The researchers said: “Oilfields in Saudi Arabia showed the lowest average GHG intensities due to highly productive reservoirs (high productivity index), low water production (leads to lower mass lifted and less energy expenditure in separation per unit of oil extracted) and low flaring rates.”
Ahmad Al-Khowaiter, Aramco’s chief technology officer, said that the findings showed the value of the big research and development program that the Saudi national oil company has made one of its main business priorities.
“It is good business, not just good environmental practice. We are the lowest cost producer, and the lowest emissions producer. It will help achieve sustainability through greater energy efficiency,” he said.
China is the biggest oil consumer in the world, but is also a major environmental polluter, mainly because it continues to use local coal as its main energy source.
The CERAWeek event has sought to understand the country’s new attitude toward the environment, dubbed “making China skies blue again” by the government.
Mikael Höök, an energy scientist at Sweden’s Uppsala University, said: “Documenting the emissions and net energy of a crude supply could be essential to meeting national emission and energy security targets.
“The data presented by Nature Energy indicates that the impact of replacing or phasing out just the most carbon-intensive 10 percent of Chinese oil imports could be significant — not just for continuing climate-informed energy strategies but also for geopolitical and energy security reasons, such as avoiding potentially risky suppliers in regions with security concerns.
“Improved understanding of Chinese oil policies and import preferences are, therefore, vital for modeling emission trends on local and global scales with a nuance that can inform policy realistically,” he said.


Fear of food shortages after Beirut explosion hits grain reserves

Fear of food shortages after Beirut explosion hits grain reserves

  • Beirut port silos had capacity for 120,000 tons

BEIRUT: Lebanon’s main grain silo at Beirut port was destroyed in a blast, leaving the nation with less than a month’s reserves of grain but enough flour to avoid a crisis, the economy minister said on Wednesday.

Raoul Nehme told Reuters a day after Tuesday’s devastating explosion that Lebanon needed reserves for at least three months to ensure food security and was looking at other storage areas.

The explosion was the most powerful ever to rip through Beirut, a city torn apart by civil war three decades ago. The economy was already in meltdown before the blast, slowing grain imports as the nation struggled to find hard currency for purchases.

“There is no bread or flour crisis,” the minister said. “We have enough inventory and boats on their way to cover the needs of Lebanon on the long term.”

He said grain reserves in Lebanon’s remaining silos stood at “a bit less than a month,” but said the destroyed silos had only held 15,000 tons of the grain at the time, much less than capacity which one official put at 120,000 tons.

Beirut’s port district was a mangled wreck, disabling the main entry point for imports to feed a nation of more than 6 million people.

Ahmed Tamer, the director of Tripoli port, Lebanon’s second biggest facility, said his port did not have grain storage but cargoes could be taken to warehouses 2 km (about one mile) away.

Alongside Tripoli, the ports of Saida, Selaata and Jiyeh were also equipped to handle grain, the economy minister said.

“We fear there will be a huge supply chain problem, unless there is an international consensus to save us,” said Hani Bohsali, head of the importers’ syndicate.

UN agencies are meeting on Wednesday to coordinate relief efforts for Beirut, Tamara Al-Rifai, a spokeswoman for the Palestinian refugee agency UNRWA, said from Amman. “People are extremely poor, it’s increasingly difficult for anyone to buy food, and the fact that Beirut is the largest port in Lebanon makes it a very bad situation,” she said.

“We are looking at Tripoli, but it is a much smaller port.”

Reserves of flour were sufficient to cover market needs for a month and a half and there were four ships carrying 28,000 tons of wheat heading to Lebanon, Ahmed Hattit, head of the wheat importers union, told Al-Akhbar newspaper.

Lebanon is trying to transfer immediately four vessels carrying 25,000 tons of flour to the port in Tripoli, one official told LBCI news channel.
