Hydrogen, which has a diverse range of applications and can be deployed in a wide range of industries, can be produced in a number of ways. One method includes using electrolysis, with an electric current splitting water into oxygen and hydrogen.

If the electricity used in this process comes from a renewable source such as wind or solar then some call it green or renewable hydrogen. The electrolyzer in Zhangjiakou will use onshore wind power, Shell said.

While there is excitement in some quarters about green hydrogen’s potential, the vast majority of hydrogen generation is currently based on fossil fuels.

Sweeney responded: “Sounds doable, account and all my help. Any chance to up that to $50K?”

The 19-year-old cited college funding and told the billionaire the money could go towards buying a Tesla Model 3.

“I’ve done a lot of work on this and 5k is not enough,” Sweeney said in an interview with Insider. He added $5,000 wasn’t enough to replace “the fun I have in this, working on it.”

“The main goal is to build a smart new city, a new city that is competitive at the global level, to build a new locomotive for the transformation… toward an Indonesia based on innovation and technology based on a green economy.”

Environmental groups not on board However, not all are on board with Widodo’s new plans. Environmental groups worry that the new city may disturb the orangutans, leopards, and other wildlife that already live there. There is also the fact that the new development would cost a whopping $34 billion, a price much too high to pay during an already costly pandemic.

Pretty soon it won’t just be Indonesia’s Navy submarine that will have disappeared. Its capital city Jakarta is also sinking quickly.

Indonesia is looking to replace its capital city because it is very polluted, congested, susceptible to earthquakes, and quickly sinking, according to the Associated Press. The country now aims to build a more sustainable, cleaner, and resilient capital city.

The Industrial Internet of Things (IIoT) connects IoT with Industry. The IIoT allows companies to reap information from their machines and environments to create intelligent, self-learning machines. This interconnected ecosystem provides numerous benefits for enterprises, such as reduced downtime, increased throughput and safety, and predictive maintenance — leading to greater efficiency. The 4th Industrial Revolution is fueled by exponential advancements in digital technology and brings us closer to a sustainable future of intelligent manufacturing environments that operate with zero emissions. With the advent of Industry 4.0, there has been a massive increase in the levels of data being produced by intelligent machines. This enormous increase in information can be hard to manage and analyze effectively without converting into usable insights. These insights are gained through the use of various technologies, including intelligent digital twins that allow for real-time monitoring of a machine’s condition, AI that can analyze large amounts of data to produce actionable insights, and connected devices that provide live status updates.

Energy company Royal Dutch Shell has started operations at the power-to-hydrogen electrolyzer in Zhangjiakou, China, a joint venture between Shell (China) and Zhangjiakou City Transport Construction Investment Holding Group, the Anglo-Dutch company wrote on Friday. The electrolyzer will reportedly provide about half of the total green hydrogen supply for fuel cell vehicles at the Zhangjiakou competition zone during this year’s Winter Olympic Games, set to begin on February 4. Shell looks set to make further investments in China’s hydrogen sector. “We see opportunities across the hydrogen supply chain in China, including its production, storage and shipping. We want to be the trusted partner for our customers from different sectors as we help them decarbonise in China,” commented Wael Sawan, director of Shell’s Integrated Gas, Renewable and Energy Solutions unit. The companies, which took 13 months to complete the project, have plans to scale the power-to-hydrogen electrolyzer up to 60 MW in the next two years. Utilizing onshore wind power, the project will initially supply green hydrogen to fuel a fleet of more than 600 fuel cell vehicles at the Zhangjiakou competition zone during the Winter Olympic Games. After that, the hydrogen will be used for public and commercial transport in the Beijing-Tianjin-Hebei region.

Green Hydrogen Systems, a provider of pressurized alkaline electrolyzers used in on-site hydrogen production based on renewable electricity, has signed a supply agreement with Edinburgh-based Logan Energy to deliver electrolysis equipment for a project in England. The order includes the supply of two electrolyzers with a combined capacity of 0.9 MW for the production of green hydrogen from renewable energy. “Manufactured by Green Hydrogen Systems and operated by Logan Energy, the electrolysers will be deployed in a 40 ft container as a complete green hydrogen plant as part of plans to develop a regional hydrogen economy in Dorset, England,” Green Hydrogen Systems wrote on Tuesday. When fully operational during Q4 of 2022, the ordered electrolyzers will reportedly have the capacity to provide approximately 389 kg green hydrogen per day.

The company sold roughly one million cars in 2021.

The electric vehicle manufacturer announced yesterday that it made $5.5 billion in profits last year after selling nearly one million cars. That’s six times more than it did in 2020. But even those numbers weren’t enough to reassure investors that Tesla’s future success is a sure thing.

Surprisinglyfell sharply after the announcement because it also disclosed that supply chain problems have been forcing Tesla factories to run below capacity for months. Its 2022 outlook was also short on details about when new factories will come online, according to several analysts. Meanwhile, rival EV manufacturers are on the rise as the might of U.S. and global auto manufacturing shifts momentum into sustainable, electric vehicles.

“This is not ‘SpaceX did something bad’—it’s perfectly standard practice to abandon stuff in deep orbit,” writes McDowell. “This is ‘none of the space agencies care about leaving stuff out beyond the Moon’.”

However, with the age of commercial space industry there’s going to be a lot more junk like this. Something needs to be done. “It’s time for the world to get more serious about regulating and cataloging deep space activity,” writes McDowell. ## Why we need to launch rockets and satellites.

There seems to be a swell of doubt around whether the carbon footprints of rocket launches can be justified in this age of rampant climate change. Attaching the term “space junk” and Elon Musk’s name instantly make it a big and negative story.

When is the SpaceX rocket going to crash into the Moon?

On February 11, 2015 a Falcon 9 rocket from Elon Musk’s SpaceX launched from Cape Canaveral. After sending the Deep Space Climate Observatory (DSCOVR) satellite into an orbit where there’s an unhindered view of the Sun the rocket’s spent upper stage went into a chaotic elliptical orbit of Earth.

Developed in Spain, the Arca system integrates solar panels, power electronics, and energy storage. Arca Lite has a rated power of 490 Wp, and Arca Plus of 980 Wp.

From pv magazine Latam

The Spanish companies Solartia and IED — experts in energy and electronics, respectively — have launched Arca, an autonomous solar power generator described as a robust and low-maintenance system that aims to alleviate energy poverty.

The system integrates solar panels, power electronics, energy storage and prepayment in a compact, robust and simple way, which allows it to be able to supply energy permanently anywhere in the world, according to the manufacturer. The solution is also designed to be installed in any location without qualified personnel.
