Photoncycle aims to store energy cheaply using a clever hydrogen solution

Published

on

The solar energy sector has been fighting interseasonal energy storage for years. The ability to harness surplus solar energy through the summer months for winter use stays an elusive goal, with existing solutions equivalent to batteries becoming insufficient due to prohibitive costs and limited lifespan. Meanwhile, hydrogen, despite its clean-burning properties, has been sidelined due to inefficiency and high costs.

Photoncycle — a startup emerging from the depths of an accelerator on the Oslo Science Park in Oslo, Norway — is working on a solution. Startup claims that with a vision as clear because the summer sun, solid hydrogen technology can store energy more efficiently ammonia synthesis reactor. The claim is that this technology provides more economical storage than every other battery or liquid hydrogen solution available on the market.

“Lithium-ion batteries use expensive metals. Our material is super cheap: storing 10,000 kilowatt hours costs about $1,500, so it’s almost nothing. In addition, our data storage solution is 20 times more dense than a lithium-ion battery and does not waste electricity,” explains founder and CEO Bjørn Brandtzaeg in an interview with TechCrunch. “This means we have a system where energy can be stored over time, allowing for seasonal storage. This is completely different from traditional batteries.”

Photoncycle uses water and electricity to produce hydrogen. This in itself will not be unusual in the event you follow fuel cell vehicle technology. However, the corporate’s approach includes an progressive twist: a reversible, high-temperature fuel cell. This advanced fuel cell can produce hydrogen and generate electricity in the identical device.

The core of Photoncycle’s innovation is hydrogen processing. They process hydrogen after which use technology to convert and store it in solid form. The company claims that this storage method will not be only secure due to the non-flammable and non-explosive nature of the solid, but in addition highly efficient. It enables the storage of hydrogen with a density roughly 50% greater than liquid hydrogen, which is a significant advance in hydrogen storage solutions. These innovations form the cornerstone of the Photoncycle system, facilitating the secure and dense storage of hydrogen, which the corporate says represents a huge breakthrough in energy technology.

Current clean energy solutions, equivalent to rooftop solar, are limited by inconsistent supplies due to the unpredictable nature of weather conditions. A sturdy reusable energy storage solution could overcome these schedules, ensuring a stable energy supply when these renewable sources encounter inevitable intermittent periods.

Great in theory, but not without its own challenges.

“The Netherlands is the country in Europe with the highest density of rooftop solar energy. We are currently seeing huge growth due to high energy prices; everyone wants rooftop solar,” Brandtzaeg says. However, he adds that this method can backfire for homeowners: “Last July within the Netherlands in the midst of the day it was 500 euros per megawatt hour to export electricity

Placing energy storage along with an energy-producing house effectively allows homes to be disconnected from the grid. Photoncycle says it has tested and worked with the core components of its solution – the following step is to integrate it into the system. The company says that if successful, it could seriously threaten Powerwall, Tesla’s lithium-ion battery solution.

“It’s a relatively complex system – that’s why so many PhDs from different fields are working on it. The reason why Elon Musk said hydrogen is stupid is because you lose a lot of energy when you convert electricity into hydrogen and vice versa,” says Brandtzaeg. He believes his company can turn this bug into a feature. “In residential buildings, where 70% of energy demand is for heating, it is possible to use excess heat to provide hot water. We will focus on markets where people currently use natural gas for heating, and then we will replace the gas boiler in the home, using existing water infrastructure.”

Brandtzaeg’s confidence within the operational framework of the concept is convincing. He pointed to a small model of their operating facility within the labs, scaled down to the scale of a automobile battery. Brandtzaeg believes this scaling needs to be seamless and cites it because the primary reason they felt confident in implementing the project.

When it comes to providing power, hydrogen takes a while to generate electricity, so for buffering, the corporate relies on an intermediate, more conventional battery to balance the load. The company definitely attracts the eye of investors: Photocycle has just raised $5.3 million (€5 million) to construct the primary few energy storage devices in Denmark, which Photoncycle has chosen as its test market.

“Based on the interest, we could have raised 10 times more than we did. However, after this increase, I am still the majority owner,” says Brandtzaeg. “I wanted to maintain control of the company for as long as possible and not raise more capital than necessary to bring this service to market.”

Palantir Exec defends work in the company’s immigration supervision

Published

By

One of the founders of the Y startup accelerator Y Combinator offered this weekend the Palantir Data Analytical Company that doesn’t describe the controversial analytical company, running the company’s director to supply a broad defense of Palantir’s work.

Then it appeared forward federal applications He showed that American immigration and customs enforcement (ICE) – the task of conducting the aggressive strategy of the deportation of the Trump administration – pays Palantir $ 30 million for creating What does this call the immigration system operating systemSo immigration to assist ICE resolve who to direct to the deportation, and likewise offer “real -time visibility” in self -complacency.

Y founding father of Combinator Paul Graham divided the headlines about the Palantir contract on the subject of XWriting: “It is now a very exciting time in technology. If you are a first -rate programmer, there is a huge number of other places where you can work, and not in a company building infrastructure of a police state.”

In response, the global business head of Palantir Ted Mabrey wrote that “he is looking forward to the next set of employees who decided to submit a request to Palantir after reading your post.”

Mabrey didn’t discuss the details of the current work of Palantir with ice, but said that the company began cooperation with the Internal Security Department (in accordance with which ICE works) “in an immediate response to the assassination of agent Jaime Zapata by Zetas in an effort called Fallen Hero surgery. “

“When people live because of what you built and others were not alive, because what you built was not good enough yet, you develop a completely different view on the meaning of your work,” said Mabrey.

He also compared Graham’s criticism with protests on the Google Maven project in 2018, which ultimately prompted the company to stop the work of drone photos for the army. (Google then signaled that he again became more open to defense works.)

Mabrey called everyone interested in working for Palantir to read the latest book CEO Alexander Karp “The Technological Republic”, which claims that the software industry must rebuild its relationship with the government. (The company was Recruitment at university campus With signs declaring that “the moment of counting arrived west”)

“We employ believers,” Mabrey continued. “Not in the sense of the homogeneity of religion, but in the internal ability to imagine in something greater than you

Graham then Pressed Mabrey “To publicly commit himself on behalf of Palantir, so as not to build things that help the government violate the US constitution,” although he confirmed in one other post that such a commitment “would not have legal force.”

“However, I hope that if (they make a commitment) and a Palantir’s employee is one day asked to do something illegal, he will say” I didn’t join for it “and refused,” wrote Graham.

Mabrey in turn compared Graham’s query In order for “or” you promise to stop beating a trick in court, but he added that the company “has made so many ways from Sunday”, ranging from the commitment to “3,500 thoughtful people who polish only because they believe that they make the world a better place every day because they see their first hand.”

3 The leaders of the Energy and Trade Committee said that they’re investigating how 23ndme’s bankruptcy can affect customer data.

Representatives of Brett Guthrie, Gus Biliakis and Gary Palmer (all Republicans) He sent a letter On Thursday, Joe Selsavage, Joe Selsavage, ask a variety of questions about how 23andme will serve customer data if the corporate is sold.

The letter also says that some customers have reported problems with deleting their data from the 23ndme website, and notes that corporations directly for consumption, reminiscent of 23andme, are generally not protected by the Act on the portability and accountability of medical insurance (Hipaa).

The Covid.gov government website has used Covid-19, tests and treatment to store information. Now, under the sight of President Trump, page redirects to the side of the White House Talking to the unverified theory that Covid-19 comes from the Chinese laboratory.

A theory during which many virologists have objected to in the report Through House Republicans last yr, which found that Pandemia began with a laboratory leak in China. House democrats He spent the overthrow At that point, the statement that the probe didn’t define Cavid’s real origin.

Covidtes.Gov website, during which people could order free coronavirus tests before, can be redirected to this New page.

The latest website of the White House also includes medical disinformation on the treatment of the virus, falsely claiming that social distance, mask and lock fines should not effective in alleviating the spread of Covid-19. However, Hundreds of research They showed that these preventive measures In fact, reduce respiratory infections equivalent to Covid-19.

In the months, since Trump again confirmed his role of the US president, many web sites have been edited to reflect the program of his administration. With the help of Doge Elona Musk, the government tried to remove tons of of words related to diversity from government documents. This Include Words equivalent to “black”, “disability”, “diversity”, “sex”, “racism”, “women” and lots of more. The government also removed the mention of scientifically proven climate change from environmental sites.
