The Hydrogen Stream: Hydrogen system for marine vessels

Posted by in categories: climatology, government, sustainability

Duisburg, a massive inland port in Germany, is building a new container terminal on a former coal island. The port will reportedly become climate neutral via a hydrogen-based supply network that is set for operation by 2023. “Our mtu fuel cell solutions for electrical peak load coverage as well as mtu hydrogen heat and power generation station will supply the future terminal with electrical energy and heat in a sustainable way,” said Rolls-Royce Power Systems. The hydrogen-powered mtu fuel cell solutions will supply electrical power as soon as the public grid reaches its limits, while waste heat will partly be used to heat buildings around the port.

CWP has signed a framework agreement with the government of Mauritania to develop a planned 30 GW green hydrogen project. The $40 billion AMAN project will include 18 GW of wind capacity and 12 GW of solar. It will generate approximately 110 TWh per year at full capacity.

What is Kinetic 7 and is it the Breakthrough Energy Source the Hype is Promoting or is it a Hoax?

Posted by in categories: business, economics, security

Voltage Enterprises is an Abu Dhabi-based company founded a year ago. It describes itself as a disruptive energy innovator. It claims to have invented a zero-carbon emissions fuel that is cheaper than natural gas. It calls the fuel Kinetic 7 ™. The information I received states:

“The clean gas, which is carbon neutral with net-zero emissions, will give global economies access to a cheap, endless supply of clean energy. Importantly, it will allow countries to maintain the security of their gas and energy supplies whilst also meeting their carbon-neutral net-zero targets. This discovery could play a major role in reversing the global energy crisis, significantly reducing energy costs to the consumer and businesses sectors at a time when the cost-of-living crisis is worsening, and inflation has reached a 40-year high.”

If that doesn’t sound fantastic to you then I am surprised. Kinetic 7 is purportedly manna from heaven for the energy industry or represents disruptive change on a global scale. So which is it and what is it?

Dogs found to be effective for mass screening people for COVID-19

Posted by in category: biotech/medical

A team of researchers affiliated with several institutions in France and one in the United Arabian Emirates, has found via testing that dogs may be as effective at mass screening people for COVID-19 as publicly available tests. In their paper published on the open-access site PLOS ONE, the group describes how they tested multiple dogs sniffling human sweat samples for COVID-19 and how well they did.

Prior research has suggested that can smell it when someone near them has a disease, such as cancer. Some research has also suggested that dogs might be able to do the same with COVID-19. To find out if that is indeed the case, the researchers tested the sniffing ability of multiple dogs faced with multiple samples.

To test their ability to recognize COVID-19, multiple dogs were trained to sniff samples of human sweat and to sit down if they detected the virus. Training was done in ways similar to that done with dogs trained to sniff out explosives. Once they were tested, the dogs were taken to the Alfort School of Veterinary Medicine where cones had been set up with sweat samples in them.

An Actively Exploited Microsoft Zero-Day Flaw Still Doesn’t Have a Patch

Posted by in category: security

“After public knowledge of the exploit grew, we began seeing an immediate response from a variety of attackers beginning to use it,” says Tom Hegel, senior threat researcher at security firm SentinelOne. He adds that while attackers have primarily been observed exploiting the flaw through malicious documents thus far, researchers have discovered other methods as well, including the manipulation of HTML content in network traffic.

“While the malicious document approach is highly concerning, the less documented methods by which the exploit can be triggered are troubling until patched,” Hegel says. “I would expect opportunistic and targeted threat actors to use this vulnerability in a variety of ways when the option is available—it’s just too easy.”

The vulnerability is present in all supported versions of Windows and can be exploited through Microsoft Office 365, Office 2013 through 2019, Office 2021, and Office ProPlus. Microsoft’s main proposed mitigation involves disabling a specific protocol within Support Diagnostic Tool and using Microsoft Defender Antivirus to monitor for and block exploitation.

Global plastic use and waste on track to triple by 2060

Posted by in categories: economics, energy

A world severely blighted by plastic pollution is on track to see the use of plastics nearly triple in less than four decades, according to findings released Friday.

Annual production of fossil-fuel-based plastics are set to top 1.2 billion tonnes by 2060 and waste to exceed one billion tonnes, according to the Organisation for Economic Co-operation and Development (OECD).

Even with aggressive action to cut demand and improve efficiencies, plastic production would almost double in less than 40 years, the 38-nation body projects in a report.

Study finds groundwater depletion causes California farmland to sink, suggests countermeasures

Posted by in categories: climatology, sustainability

The floor of California’s arid Central Valley is sinking as groundwater pumping for agriculture and drinking water depletes aquifers. A new remote sensing study from Stanford University shows land sinking—or subsidence—will likely continue for decades to centuries if underground water levels merely stop declining. To stop the sinking, water levels will need to rise.

“If you don’t get these to come back up, then the land is going to sink, potentially tens of centimeters per year, for decades. But if they go up, you can get rewarded very quickly. You almost immediately improve the situation,” said Matthew Lees, a geophysics Ph.D. student and lead author of the study, which appears June 2 in Water Resources Research.

The research comes amid worsening drought in a state where is tipping the odds toward hot conditions with more precipitation extremes. The first four months of 2022 marked California’s driest start to a year since 1895. Reservoir levels are so low that, for a second year in a row, many irrigation districts are poised to receive none of their usual allocations of water from the Central Valley Project, the federally managed network of reservoirs and canals that conveys water to some 3 million acres of farmland.

21 oil wells now found leaking methane near California homes

Posted by in category: energy

A total of 21 oil wells have been found to be leaking methane in or near two Bakersfield neighborhoods, and more than two dozen are being tested by state and regional air regulators.

California Geologic Energy Management Division, or CalGEM, said in an update on its website that state and regional air regulators are in the area again today to interview residents and take additional methane readings.

Repairs are at various stages for the nearly two dozen wells, several of which were found to be leaking at least 50,000 parts per million of methane — a level at which the colorless, odorless gas can explode if ignited.
