Turkish entrepreneurs build first hydrogen-powered scooter

Posted by in category: energy

E-scooters are all the rage in Türkiye, as their sales and number of companies renting them soared in recent years. Yet, they have several cons, like long charging times and possible pollution from the uncontrolled disposal of discarded batteries. Four Turkish engineers hope a new scooter, working on hydrogen power, may overcome these problems.

“Hebunk,” devised by entrepreneurs working at a technology park at Istanbul Technical University, boasts a fast charging time, just five minutes, and can travel for 60 kilometers (37.28 miles) with a single charge, which roughly costs about 9 cents (TL 1.8).

The scooter, which is not too different from e-scooters in appearance, was developed in one year by the entrepreneurs’ HydroBorPEM Fuel Cell Technologies, now based at a technology park in Istanbul’s Yıldız Technical University.

Penguin feathers may be secret to effective anti-icing technology

Posted by in categories: chemistry, drones, energy, engineering, sustainability

Ice buildup on powerlines and electric towers brought the northern US and southern Canada to a standstill during the Great Ice Storm of 1998, leaving many in the cold and dark for days and even weeks. Whether it is on wind turbines, electric towers, drones, or airplane wings, dealing with ice buildup typically depends on techniques that are time consuming, costly and/or use a lot of energy, along with various chemicals. But, by looking to nature, McGill researchers believe that they have found a promising new way of dealing with the problem. Their inspiration came from the wings of Gentoo penguins who swim in the ice-cold waters of the south polar region, with pelts that remain ice-free even when the outer surface temperature is well below freezing.

We initially explored the qualities of the lotus leaf, which is very good at shedding water but proved less effective at shedding ice,” said Anne Kietzig, who has been looking for a solution for close to a decade. She is an associate professor in Chemical Engineering at McGill and the director of the Biomimetic Surface Engineering Laboratory. “It was only when we started investigating the qualities of penguin feathers that we discovered a material found in nature that was able to shed both water and ice.”

‘Accidental power trip’ leads scientists to discover new way of generating hydrogen

Posted by in category: energy

It all started in 2019 when the team’s lab lights went out for one night.

Researchers from the National University of Singapore (NUS) stumbled upon a discovery that could forever revolutionize how we acquire hydrogen from water, according to a press release from the institution published on Thursday.

‘Wind Challenger’: World’s first partially wind-powered cargo ship successfully sailed

Posted by in categories: energy, sustainability, transportation

It is the first coal carrier to be powered by hard sail wind power propulsion technology.

The world’s first partly wind-powered bulk carrier ship sailed to the Port of Newcastle on its maiden voyage this week. The Japanese shipping company Mitsui O.S.K. Lines (MOL), which delivered the 100,422 dwt (dead-weight tonnage) bulker on October 7, 2022, sailed to Newcastle on Monday, reported Offshore Energy.

2D nanoconfinement strategy enhances oxygen evolution performances

Posted by in categories: chemistry, energy, engineering, physics, sustainability

Prof. Zhang Tao’s group at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. Hou Yang from Zhejiang University and Prof. Xiao Jianping from the Dalian Institute of Chemical Physics of CAS, proposed a novel two-dimensional (2D) nanoconfinement strategy to strongly enhance the oxygen evolution reaction (OER) activity of low-conductivity metal-organic frameworks (MOFs). Results were published in Nature Communications.

The development of high-efficiency electrocatalysts for the electrochemical conversion of water to generate environmentally friendly and sustainable hydrogen energy has drawn tremendous attention for decades.

Despite the crucial role the OER plays in water splitting, OER at the anode requires a relatively high thermodynamic potential to accelerate water splitting kinetics. Thanks to the large surface area, tunable porosity, diverse compositions and metal centers, MOFs have emerged as promising candidates for efficient OER electrocatalysts. However, the intrinsically poor conductivity of the most MOFs seriously impede their .

China to break its own record: World’s new largest wind farm could power 13 million homes

Posted by in category: energy

The 10-kilometer-long offshore farm would be bigger than all of the power plants in Norway combined.

China plans to break its own record for the world’s largest wind farm by constructing a new one before 2025 that could power more than 13 million homes.

Work on the project will begin “before 2025.” It will surpass the largest wind farm in the world once it is finished, according to Guangdong province officials.

World’s largest salt cavern compressed air storage project breaks ground

Posted by in categories: energy, engineering

Compressed air energy storage (CAES) is expected to play a key role in China’s clean energy push and the latest project announcement attests to the fact.

According to a media statement from the state-owned Assets Supervision and Administration Commission of the State Council, construction started on a 350 MW/1.4 GWh CAES project in the province of Shangdong on September 28.

Once completed, the Tai’an demonstration project is expected to be the world’s largest salt cavern CAES project, comprising two units for a total of 600 MW. The 350 MW system, which will be delivered in the first phase, is being jointly built by China Energy Engineering Group and Tai’an-based Taian Taishan New Energy Development to the tune of CNY 2.23 billion ($311 million).

How one startup plans to increase EV range

Posted by in categories: energy, sustainability, transportation

It will also increase energy density by 30 percent.

The innovative UK start-up Ionetic, specializing in EV battery pack technology, introduced its cutting-edge EV battery pack design platform, which can shorten the time and cost of development for automakers developing new electric vehicles.

It has traditionally been expensive and time-consuming for many automobile firms to provide a high-performance and secure battery pack solution. Fully customized designs are frequently out of reach for most consumers, while current off-the-shelf battery pack solutions have low energy density and optimization. This is especially true for specialty, low-volume automakers who have particular needs.
