The steam methane reforming process can be coupled with carbon capture and storage technology to cut CO2 emissions but the cost of producing hydrogen carbon capture and storage is about 45 per cent higher. And the cost of CO2 avoidance is also high, at about €70 per ton.  This is not financially viable and would require technological breakthroughs in carbon capture and storage to become a sustainable solution.

“This work represents a breakthrough that will bring inexpensive generation of green hydrogen from renewables much closer to reality,” he said.

BTW. Good to see some posts have been “let through to have a historical record about the nonsense spouted off by these promoters”. Hopefully this page will be left up too, so as Wolf’s claim it’s a scam will have a historical record too.

Cell construction and materials are limited by physics and atomics. Unless some unknown mysterious element arrives with some alien space being (with huge quantities of it) incremental improvements of current technology will prevail.

On the other hand, once the main risk factors are identified, pollution may prove easier to curb indoors than out, precisely because the space is more confined. It’s taken nearly fifty years for the United States to successfully reduce outdoor ozone and particulate concentrations, whereas much of the particulate matter from cooking can probably be removed by measures as simple as investing in a decent exhaust hood and replacing its filter frequently. John Balmes already has data suggesting that running an exhaust hood while cooking correlates with a steep reduction both in household particulate levels and in childhood asthma attacks. Benjamin Franklin’s advice to open the window is worth following, too, particularly when mopping or making toast—provided, of course, that the air outside is clean.

Wasn’t there a story during the tulip mania of a Dutch merchant’s servant who ate one of his master’s enormously expensive tulip bulbs, stupidly thinking it was an onion, and consequently being sent to prison for theft – when the price of tulips collapsed to common vegetable levels, his master got out of jail, stating that he himself was the biggest fool.

A possible lower cost solution is to increase the relative surface area of air bubbles sparged into fermentor media. By reducing the bubble size, the oxygen transfer rate of the fermentor can be increased due to greater surface area. Furthermore, the velocity of the bubbles traveling from the bottom of a fermentor to the top is reduced, giving more time for oxygen transfer to the culture media. A microbubble dispersion (MBD) generator can reduce the size of a conventional sparged gas bubble from 3–5 mm to approximately 20–100 µm [20, 22]. Additionally, it has been suggested that microbubble sparged fermentors can be energy efficient up to 0.01 kW/m3 of fermentation capacity, providing lower overall operating costs [23].

Microgels have been used for many years as model systems to study the fundamental physics of the jamming and glass transitions (6, 8, 10). For an even longer period, dating back to the 1950s, microgels have been used in the industry to control the rheological behaviors of diverse products from engine oils to personal care products, such as lotions, shampoos, conditioners, and hand sanitizers (3, 39–41). In contrast to aqueous microgels, organic microgel applications have remained limited by the challenges of microgel synthesis and swelling in nonpolar liquids. Here, we have developed an oil-based microgel system by leveraging one of the most well-controlled and versatile tools in the soft matter research world: the self-assembly of block copolymers. We used commercially available components and demonstrated the tunability of the material’s rheological and interfacial properties. Our results demonstrate the ability of these microgels to meet the manufacturing requirements of soft silicone devices without significant constraints on ink formulation or fabrication machinery. Furthermore, we hope that this work will enable other researchers to investigate the huge diversity of possible block-copolymer chemistries, expanding the breadth of physical and chemical properties of micro-organogels for new technological applications, including improved soft matter manufacturing methods.

What’s more, he felt the BLM—the government’s main leasing agency — wasn’t accurately assessing the ozone impact of new wells. After years of pushing, the EPA in 2011 crafted a memorandum of understanding with the Bureau and other agencies overseeing federal land, asking them to evaluate air-quality impacts before any leasing or permitting decisions and to help the EPA get a better picture of future emissions sources. It also encouraged agencies to consider alternative leasing options or controls on wells to reduce toxic emissions.

ICE engines and drivetrains are complex, but they are not that expensive, with reliability that should see say ten years trouble free use, they are just recyclable/reparable at choice, and remembering EVs generally take more energy to make into the equation.

I live in the UK and we run on 220-240v 50mhz for home supply. At night my home runs on less than 1kw/hr after we have had our cocoa and retired to bed. Apart from some homes who run storage heaters which use off peak electricity on a special tariff, most homes use little electricity at night. The UK Government has stated that it is policy that all petrol and diesel cars will be banned after 2040.
