Cambridge, England — Scientists have lengthy mentioned slicing methane emissions is essential to addressing local weather change, however many large industries aren’t readily capable of curb their manufacturing of the dangerous greenhouse fuel. A British firm says it has a solution: Flip methane into one thing else.
Methane is a menace. Local weather scientists say the invisible fuel warms the Earth’s environment 84 instances quicker than carbon dioxide. It is launched into the environment by natural materials, equivalent to meals waste, rotting at landfill websites, sewage remedy amenities and by the digestive systems of cows.
Levidian — a local weather tech enterprise in Cambridge, England — got down to deal with this local weather change problem, by giving methane a makeover.
“The magic occurs in right here,” the corporate’s CEO John Hartley advised CBS Information as he led our group on a guided tour of Levidian’s patented LOOP system — a machine with a large metallic hopper formed like a balloon.
The know-how makes use of microwave power and a particular nozzle system to separate methane molecules into the fuel’ part components — hydrogen and carbon — and captures them.
Hydrogen is more and more wanted, as it can be used to power factories, vehicles, ships and different equipment. Levidian mentioned it is a clear gasoline, as a result of, when burned, it yields warmth and power, however the one emission is water vapor, no carbon dioxide.
The carbon from the broken-down methane, in the meantime, falls into the hopper as a stable known as graphene, which has been recognized to science for under about 20 years and which is usually touted because the strongest material in the world.
Dr. Ellie Galanis, head of business improvement at Levidian, was eager to point out off a harvest of graphene from the LOOP hopper on the firm’s lab.
“It is such an thrilling time to be concerned in graphene,” mentioned the self-described “graphene geek,” shaking a dice crammed with black, powder-like materials. “It is superior.”

Galanis and her group have been busy engaged on methods to make use of the graphene Levidian produces to spice up the sturdiness of on a regular basis merchandise.
“Whenever you put graphene into the tire tread, you can also make it stronger. You may make it last more and you can also make it extra gasoline environment friendly,” she mentioned of 1 software.
They’ve additionally tried including it to concrete.
“With out graphene, it tends to crumble quite a bit simpler, however with graphene it is a lot stronger,” she mentioned.
The super-strong however versatile materials may even be included within the manufacture of medical gloves.
“When surgeons do the ‘snap take a look at,’ they’re making an attempt to test if it can break, and that does not occur once you add graphene in — it makes them a lot stronger and extra puncture resistant,” she advised CBS Information.
Scientists say graphene additionally helps enhance battery life in electrical automobiles, and it may be combined into plastic to assist manufactures use much less petroleum-derived supplies of their bottles.
Researchers solely found graphene 20 years in the past, on the College of Manchester, and Levidian sees years of development forward for the product.
“Whenever you get in your automotive, you’ll have graphene enhanced tires that last more. The battery in that automotive, if it is electrical, will take you additional as a result of it can have extra capability to cost quicker, and the concrete you utilize within the constructing you go into might be extra sturdy and have a smaller carbon footprint,” she predicted, including that even “the garments that you simply put on might need graphene in them so that they’re extra sustainable.”
Levidian says its LOOP system has now reached the U.S., with Georgia-based cable maker Southwire utilizing it to scale back its carbon footprint.
