Solar panels for hydrogen production hit the market



Rooftop solar panels that capture sunlight and water from the air will soon become a reality. Like photovoltaic panels, hydrogen panels will be connected, but with gas pipes rather than electrical cables.

KU Leuven researchers develop solar panels to produce hydrogen

This new solution will soon be on the market through a partner company.

For more than ten years, researchers have been developing and refining this technology, and the final prototype has been embodied in an attractive design. Komate Engineering and Design.

How do solar panels work to produce hydrogen?

A hydrogen solar panel converts water vapor in the air into hydrogen using sunlight. The researchers guarantee that they can produce about 250 liters of hydrogen per day. with an efficiency of 15%.

This Solhyd project has entered a phase of transition from research to investment by a partner company.

Simply put… hydrogen panels, are solar panels that split water molecules to produce hydrogen gas using solar energy. Very dry places on Earth are not suitable for this technology due to the arid environment.

These new panels are identical to traditional solar panels, but instead of an electrical cable, they are connected by gas pipes.

The top layer of the panel generates electricity, while the bottom layer is a piping system that generates hydrogen by extracting water molecules from the air through a membrane.

Solhyd Hydrogen Solar Panels

According to researcher Jan Ronge from KU Leuven, “Solhyd hydrogen solar panels are compatible with most modern photovoltaic modules and can be connected directly to the system. In this way, we can benefit from technological developments and cost reductions in the photovoltaic industry. To enhance this synergy, Solhyd hydrogen solar panels are compatible with most existing mounting structures.”.

Hydrogen solar panels are small, modular and ideal for decentralized production. It is estimated that 20 of these panels can provide electricity and heat to a well-insulated house with a heat pump all winter long.

When installed together with a solar thermal collector and traditional solar panels hydrogen solar panels can help heat homes and provide year-round electricity.

Estes solar panels do not store hydrogen, work at low pressure, so they have high safety and economy. The produced hydrogen is collected from the panel and then compressed if necessary (which allows it to be stored indefinitely). Of course, some applications do not require gas compression, or other forms of storage will be used.

The use of hydrogen produced by solar panels

Hydrogen produced by Solhyd solar panels can be used in a variety of applications such as mobility. Or for medium duty applications such as backup power, heavy hauling.

Later, with advances in technology, it will be possible to come up with any application, such as large-scale ammonia production or even small stand-alone systems.

Costs will be the same as in the photovoltaic market, as no precious metals are used in the production of these panels, which keeps the price affordable.

Since 2011, several prototypes of these solar panels have been tested, so the researchers are confident that the commercial production of these hydrogen solar panels will start.

It was in September that Solhyd began industrial development of the project, moving from university premises to a 350 square meter facility near Leuven with the help of the municipality of Flanders.

Initially, several dozen panels will be produced for use in small pilot projects. But by 2026, the team hopes to produce more than 5,000 hydrogen solar panels per year at a price similar to photovoltaic panels currently on the market.

ITA Airways may be partly in the hands of the Italian state railway



ITA Airways may be partly in the hands of the Italian state railway

The Italian government is exploring new possibilities for the sale of ITA Airways, which could involve Lufthansa and the national rail company, Ferrovie dello Stato (FS). This is reported by the Italian newspaper Corriere della Sera. Earlier this month, the government announced it would resume talks with Lufthansa after inconclusive talks with a consortium formed by Air France-KLM, Delta Air Lines and Certares.

Lufthansa said last week through a spokesperson that it remains interested in the acquisition. The original partner of the German group, the sea carrier MSC, refused to negotiate.

With FS, the Italian government, along with Lufthansa, has a new takeover candidate for the airline. Reuters news agency reports that government documents show the government wants to sell 51 percent of ITA to Lufthansa for 250 million euros, with 29 percent to go to Ferrovie dello Stato, with the rest remaining in state hands.

With the partial acquisition, ITA FS will be able to use a combination of air and rail transport. Moreover, it already offers high-speed lines connecting the main cities of Italy, the Italian newspaper writes. Cooperation can facilitate the transition to both modes of transport.

Having FS as an airline partner was nothing new, as the state-owned railway was also a shareholder in the bankrupt Alitalia. The difference here is that if there is Lufthansa in the package (if these plans are confirmed), it is the Germans who should have control and will dictate the step of the company, which is unprofitable today.

Tesla announces another recall of 80,000 vehicles, and some even have to be recalled



Imagem Tesla recall

Tesla cars suffered this year a large number of requests for “collection”better known as the process revoke🇧🇷 Trouble again and 80,000 vehicles in China will be recalled. If many of recalls was an easy decision as it was over the air (OTA) it really obliges the owners to take the car to the workshop.

In fact, this year, many millions of Tesla electric vehicles received revoke for fixes.

Many of the reviews are related to issues resolved via OTA.

Whenever there is a safety issue, the NHTSA must issue a "safety recall", even if the car manufacturer does not have to physically recall any vehicles, leading to some confusion.

Once again last month, Tesla's "1 Million Vehicles" collection of vehicles generated a lot of news as the impact on drivers was almost negligible considering the update only changed via OTA the software that runs the car system. to work with windows.

These cases have prompted Tesla CEO Elon Musk to complain about the term "recall = collection" and how it is being used in the media against Tesla. Today The American company again announced new collections in China about 80,000 cars.

13,000 Tesla electric vehicles have seat belt problems

The recall includes 67,698 imported Model S and Model X vehicles with a battery-related software issue, according to Chinese authorities. Again, the fix is ​​a simple software update. Nonetheless, this time there is also a physical collection due to the problem with the seat belt in approximately 13,000 Model 3 vehicles: 2,736 imported and 10,127 made in China.

over 20 recalls there were many collections in 2022. However, Tesla is not the only automaker to be hit by major recalls this year. OUR Ford also just confirmed that it is recalling another half a million vehicles. due to fire hazards, and many car manufacturers have also recalled millions of vehicles this year.

In any case, the fact that the vast majority of calls from electric brand a quick fix with over-the-air (OTA) software updates — rather than taking cars back to the dealership like other car manufacturers — shows that Tesla's level of connectivity to its cars is a huge advantage in the industry.

The software update system (OTA) allows the buyer to fix many problems easily and conveniently, and for Tesla itself means big money savings.

Lidl wants to dominate the fast-charging market for electric vehicles at affordable prices



Estação de carregamento, no Lidl, aberta 24 horas por dia

One of the EU’s goals for electric vehicles is to guarantee charging points so that tram drivers don’t have to worry about being on the road when they travel. To meet this need and dominate this market, Lidl intends to offer affordable prices.

We may soon see this initiative in more supermarkets.

Despite being a supermarket chain, Lidl has been guaranteeing electric vehicle charging stations in its stores for some time. However, a new journey has now begun, the launch of the first ultra-fast charging station, which has the distinction of guaranteeing a price well below what can be found on the market.

With this new equipment, in addition to the aesthetic aspects, Lidl takes on technical and cost commitments, guaranteeing the best on the market. After all, she not only placed the charger in her supermarkets, but also created, in turn, a space with protection for vehicles, users and chargers, in an area open 24/7 (i.e. 24 hours a day, 7 days in Week). . . .

This provides better visibility of the infrastructure and reduces the risk of internal combustion engine vehicles occupying space reserved for electric vehicles.

Lidl bets on affordable charging points

The first station will be installed in a Lidl supermarket near the French city of Lyon. The space is equipped with five charging points ranging from 22 to 360 kW. Thus, each client will be able to choose the one that best suits his needs.

For example, a 22 kW charger has a competitive cost of 25 cents per kWh. When we move to more powerful stations of 90, 180 or 360 kW, the price becomes 40 cents higher per kWh.

The strategy adopted by Lidl in some of its stores is already rolling out to other countries, such as Germany, where the supermarket chain is installing its first fast-charging stations, with 150kW stations priced at 48 cents per kWh.
