Scientists have built a breakthrough device that can clean dirty water and turn it into clean hydrogen fuel. The “simple” device could be used in areas without resources or places where people live off the grid. And it is just one example of the many solutions that will be required to respond to pollution and give people access to both clean fuel and water, the researchers behind it say. The system is inspired by photosynthesis, the process where plants turn light into food. But previous versions of those “artificial leaves” have required clean water sources – whereas the new device can be used with polluted water and even produce clean drinking water at the same time. As such, scientists believe that it could help solve two problems at once: making green fuel and cleaning water so that it is ready to drink. “Bringing together solar fuels production and water purification in a single device is tricky,” said Chanon Pornrungroj from the University of Cambridge, the paper’s co-lead author. “Solar-driven water splitting, where water molecules are broken down into hydrogen and oxygen, need to start with totally pure water because any contaminants can poison the catalyst or cause unwanted chemical side-reactions.” The system uses a carbon mesh to absorb light and heat, creating water favour that is then turned into hydrogen for fuel by a photocatalyst. That carbon mesh also repels water, so that the system can float and its important parts can be kept from being damaged by water. The device is also able to harness more of the Sun’s energy than previous examples, which have used only a small portion of the spectrum of light. The new system has a white layer on top to absorb UV rays, with the rest being used lower down to vaporise the water. “This way, we’re making better use of the light – we get the vapour for hydrogen production, and the rest is water vapour,” said Dr Pornrungroj. “This way, we’re truly mimicking a real leaf, since we’ve now been able to incorporate the process of transpiration.” The researchers behind the breakthrough noted that the system was simple to make, and was especially able to deal with very polluted water. As such, it could be a key way of working towards a sustainable future, they said – even though it is just a proof of concept for now. “The climate crisis and issues around pollution and health are closely related, and developing an approach that could help address both would be a game-changer for so many people,” said Cambridge’s Erwin Reisner, who led the work. The device is described in a new paper, ‘Hybrid photothermal-photocatalyst sheets for solar-driven overall water splitting coupled to water purification’, published in Nature Water today.

Whilst repairing external parts of the International Space Station (ISS) last week, astronauts dropped a toolbag. And it turns out you just need a pair of binoculars to see it. The bag is tiny compared to the ISS, but it's reflective enough that when it catches the Sun's light it reaches 6th magnitude from Earth according to Earthsky. Under very dark skies, some powerful binoculars or a small telescope might allow you to see the toolbag. The bag is moving at almost exactly the same speed as the ISS on the same path and about a minute ahead of it. Over time, however, its distance from the ISS will grow, making it harder to find. Eventually, its orbit will become low enough that it burns up from friction with the outer atmosphere. You can find out if you have the ISS passing overhead here if you want to have a chance of seeing the bag. The ISS can only be seen easily when it's dark on the ground and sunlight is still catching it. It means it's usually best seen when the skies are not fully dark - so around dusk or dawn.

The first ever commercial-scale carbon capture facility has begun operations in the US, marking a significant milestone towards meeting cleaner climate targets. San Francisco-based startup Heirloom Carbon Technologies opened the carbon removal plant in Tracy, California, on Thursday, claiming it will be able to capture 1,000 metric tons per year of CO2. The renewable energy-powered plant leverages the natural power of limestone to remove CO2 from the atmosphere. “Rocks are some of the planet’s most vital carbon sinks. Over geological timescales, CO2 from the atmosphere binds to minerals and permanently turns to rock - a process known as carbon mineralisation,” Heirloom notes on its website. “Limestone is one of the most abundant rocks on the planet, capturing massive amounts of CO2 from the air over years, Heirloom’s technology accelerates this natural process to just days.” The process works by placing hundreds of trays of calcium oxide powder onto 12-metre-tall racks, which turns into limestone as it comes into contact with CO2 from the atmosphere. Workers then heat up the limestone, which releases the carbon dioxide and turns it back into calcium oxide that can be reused to capture more CO2. The atmospheric CO2 that is captured through the facility is permanently sequestered in concrete through a partnership between Heirloom and CarbonCure Technologies. Heirloom aims to remove 1 billion tons of CO2 from the atmosphere by 2035 using its Direct Air Capture technology, with funding coming from companies buying carbon removal credits in order to offset their own emissions. It is not the first company to achieve direct carbon capture from the atmosphere, but Heirloom claims to be the first in the US. Switzerland-based startup Climeworks AG has commercial facilities in Switzerland and Iceland, which are capable of removing 4,000 metric tons of CO2 each year. Carbon capture technologies have faced criticism for the large amounts of energy and resources they require to operate, though some scientists claim they will be a vital part of keeping global net emissions below zero by 2050. In response to criticism from green groups in 2021 claiming that such projects are a costly distraction, Professor Stuart Haszeldine from Edinburgh University said: “Carbon capture and storage is going to be the only effective way we have in the short term to prevent our steel industry, cement manufacture and many other processes from continuing to pour emissions into the atmosphere. “If we are to have any hope of keeping global temperature [increases] down below 2C then we desperately need to develop ways to capture and store carbon dioxide.” The US government announced in August that it would fund a $1.2 billion effort to develop and deploy carbon capture technologies, with Heirloom among the recipients. Major companies, including Microsoft, have already signed deals to purchase carbon removal credits from Heirloom.
