The effects of global warming are becoming more serious, and there is a strong demand for technological advances to reduce carbon dioxide emissions. Hydrogen is an ideal clean energy which produces water when burned. To promote the use of hydrogen energy, it is essential to develop safe, energy-saving technologies for hydrogen production and storage. Currently, hydrogen is made from natural gas, so it is not appropriate for decarbonization. Using a lot of energy to separate hydrogen would not make it qualify as clean energy.

Polymer separation membranes have the great advantage of enlarging the separation membrane and increasing the separation coefficient. However, the speed of permeation through the membrane is extremely low, and high pressure must be applied to increase the permeation speed. Therefore, a large amount of energy is required for separation using a polymer separation membrane. The goal is to create a new kind of separation membrane technology that can achieve separation speeds that are 50 times faster than that of conventional separation membranes.

Britain announced a 25% windfall tax on oil and gas producers' profits on Thursday, alongside a 15 billion pound ($18.9 billion) package of support for households struggling to meet soaring energy bills. The move, which will give each UK household a 400 pound discount on their energy bill and more for lowest-income households, marks a change of heart for Prime Minister Boris Johnson's government, which had previously resisted windfall taxes, calling them a deterrent to investment. It is the second emergency policy intervention to help with rising bills this year.

Facing intense political pressure to provide more support for people coping with what political opponents and campaigners have called a cost-of-living crisis, finance minister Rishi Sunak said energy firms were making extraordinary profits while Britons struggled. "We will introduce a temporary and targeted energy profits levy but we have built into the new levy a new investment allowance that means companies will have a new and significant incentive to reinvest their profits," Sunak told parliament. "The more a company invests, the less tax they will pay."

Sunak did not refer to it as a windfall tax. He said it would raise 5 billion pounds ($6.30 billion) in the next 12 months and be phased out as oil and gas prices return to normal. He did not set out how the rest of the package would be funded. He also said there would be a new Investment Allowance that would nearly double the tax relief available for firms on their investments. On Tuesday the UK energy regulator said that a cap on gas and electricity bills was set to rise by another 40% in October, cause by a surge in global energy prices.

Millions of Americans traveling this holiday weekend are being greeted by unprecedented prices at the gas pump.

The national average for regular gasoline rose to a fresh record of $4.62 a gallon on Monday, according to AAA. That’s up by a penny from Sunday and 44 cents more expensive than a month ago.

Gas prices are up sharply from last Memorial Day, when they averaged $3.05 a gallon, according to AAA.

Seven states are now averaging $5-a-gallon gas, with the latest being Illinois (rounded up from $4.996). New York and Arizona are just pennies away from hitting that milestone. And there are no states where gas prices average less than $4.10 a gallon.

AMSTERDAM, May 30 (Reuters) - GasTerra will no longer receive gas from Russia's Gazprom from May 31 after refusing to agree to Moscow's demands for payment in roubles, the two companies said on Monday. GasTerra, which buys and trades gas on behalf of the Dutch government, said it had contracted elsewhere for the 2 billion cubic meters (bcm) of gas it had expected to receive from Gazprom through October.

The company is 50% owned by Dutch government entities and 25% each by Shell and Exxon(XOM.N). "We understand GasTerra's decision not to agree to Gazprom's unilaterally imposed payment conditions," Dutch Energy Minister Rob Jetten wrote on Twitter. "This decision will have no consequences for the physical delivery of gas to Dutch households." A GasTerra statement said the Dutch company had decided not to adopt the system that Russia had demanded, which involved the setting up of accounts that would be paid in euros and then swapped for roubles.

The company said such measures could violate European Union sanctions and also said the payment route presented too many financial and operational risks. A statement from Gazprom said that its suspension of gas supplies to GasTerra will continue until payments are settled in line with the Russia-proposed scheme.

GasTerra said that it had repeatedly asked Gazprom to adhere to its contractual payment methods and delivery obligations. "It is not possible to say in advance what impact the dropping off of 2 bcm of Russian gas will have on the supply and demand situation in the European market," the Dutch company added.
