LG is already one of the most prolific EV battery manufacturers in the US, but it wants to build the devices that charge them, too. The company just opened just opened its first EV charger manufacturing facility in the US, a 59,000 square foot plant in in Fort Worth, Texas capable of manufacturing 10,000 units per year.

The company has already started to assemble 11kW home-style chargers there and will begin producing 175kW fast chargers in the first half of 2024. It plans to built 350kW ultra-fast chargers at some point this year designed for “commercial travel and long-distance transportation,” LG wrote.

The Korean company said it chose Texas as it had existing facilities there and because the state offers “excellent logistics and transportation networks and is home to major operations for companies in industries ranging from automobile manufacturing to finance” (GM, Toyota and Tesla all have vehicle assembly plants in the state).

Scientists have unveiled a roadmap for bringing perovskite/silicon tandem solar cells to market, paving the way for a future powered by abundant, inexpensive clean energy in Saudi Arabia and the world.

The authors of the article, published in Science, include Prof. Stefaan De Wolf and his research team at King Abdullah University of Science (KAUST) and Technology Solar Center. The team is working on improving solar efficiency to meet Saudi Arabia’ solar targets.

Perovskite/silicon tandem technology combines the strengths of two materials— perovskite’s efficient light absorption and silicon’s long-term stability—to achieve record-breaking efficiency. In 2023, the De Wolf laboratory reported two world records for power conversion efficiency, with five achieved globally in the same year, showing rapid progress in perovskite/silicon tandem technology.

University of Michigan researchers have found that large additives could be the secret to making stable and long-lasting perovskite solar cells.

Researchers from the University of Michigan have found that large additives appear to prevent perovskite semiconductors from degrading quickly.

The KES batteries play a crucial role in reducing the curtailment of renewable energy by 69%, allowing Hawaiian Electric to integrate 10% more new utility-scale renewables than previously projected. Additionally, the project is estimated to save customers money, reducing electric bills by an average of $0.28 per month over a 20-year contract life.

The specifications of the KES plant include 135 MW / 540 MWH of capacity and energy, 50 MW / 25 MWH of additional ‘fast frequency response’ for grid stability, ‘virtual inertia’ to mimic the power-smoothing function of a spinning turbine, and ‘black start’ capabilities for grid recovery during blackouts.

Zero-emissions long-distance aviation is absolutely possible… Provided you’re not in a hurry. Solar Airship One will take 20 days to fly all the way around the equator, some 40,000 km (~25,000 miles), in a single zero-emissions hop.

The 151-m (495-ft)-long airship will have its entire upper surface covered in solar film – some 4,800 square meters (51,700 sq ft) of it, or about nine-tenths of an NFL football field for those of you who prefer the standard units.

Solar panels are already an affordable energy solution since they generate enough power over their lifetimes to pay for themselves and then some. However, they do take some investment up front, and some people (and homeowners associations) dislike the way they look.

So what if you could get that power to make electricity from sunlight without having to install solar panels? That’s the beauty of solar paint, as reported by Solar Action Alliance.

The idea behind solar paint (aka photovoltaic paint) is simple: It’d be like ordinary paint but with billions of light-sensitive particles mixed in, as Understand Solar notes.

The two-step process also produces hydrogen gas as a by-product, which could also be used as a zero-emission fuel.

“We are looking at active sites and how these sites are bonding with the reaction intermediates,” said Ping Liu of Brookhaven’s Chemistry Division. “By determining the barriers, or transition states, from one step to another, we learn exactly how the catalyst is functioning during the reaction.”

The researchers found that the iron-cobalt alloy works sequentially in the second stage and gets pushed to the side as the nanofiber grows. Using this information, the team could leach the catalysts using acid and reuse them again. If the entire process could be fueled by renewable energy, the process would be a carbon-negative approach to CO₂ mitigation.

Elysian Aircraft’s revolutionary design challenges electric aviation norms, presenting a 90-passenger plane with an 800-kilometer range, reshaping the future of sustainable air travel.

Breaking barriers in aviation! Elysian Aircraft unveils plans for a game-changing 90-passenger electric plane, pushing the boundaries of eco-friendly flight.

A team of scientists from King Abdullah University of Science and Technology (KAUST) has revealed their plan to bring a new type of solar cell to the market, one that could revolutionize the field of renewable energy. The solar cell, called a perovskite/silicon tandem, combines two different materials to capture more sunlight and convert it into electricity.

Perovskite is a material that can absorb light very efficiently, while silicon is a material that can maintain its performance for a long time. By stacking them together, the researchers have achieved record-breaking efficiency levels, surpassing the previous limits of single-material solar cells. In 2023, the KAUST team, led by Professor Stefaan De Wolf, reported two world records for power conversion efficiency and five other records achieved by other groups worldwide. This shows the rapid advancement of perovskite/silicon tandem technology and its potential to dominate the solar market.
