Concerns regarding scarcity, high prices, and safety regarding the long-term use of lithium-ion batteries has prompted a team of researchers from Rensselaer Polytechnic Institute to propose a greener, more efficient, and less expensive energy storage alternative.

In research published recently in Proceedings of the National Academy of Science (PNAS), corresponding author Nikhil Koratkar, the John A. Clark and Edward T. Crossan Professor of Engineering at Rensselaer, and his team, assert that could be used as an alternative to lithium-ions in batteries because of its abundance and low cost.

“The vast majority of rechargeable battery products are based on lithium-ion technology, which is the gold standard in terms of performance,” said Dr. Koratkar. “However, the Achilles’ heel for lithium-ion technology is cost. Lithium is a limited resource on the planet, and its price has increased drastically in recent years. We are working on an inexpensive, abundant, safe, and sustainable battery chemistry that uses ions in an aqueous, water-based electrolyte.”

We have reached a turning point in society. According to renowned theoretical physicist Michio Kaku, the next 100 years of science will determine whether we perish or thrive. Will we remain a Type 0 civilization, or will we advance and make our way into the stars?

Experts assert that, as a civilization grows larger and becomes more advanced, its energy demands will increase rapidly due to its population growth and the energy requirements of its various machines. With this in mind, the Kardashev scale was developed as a way of measuring a civilization’s technological advancement based upon how much usable energy it has at its disposal (this was originally just tied to energy available for communications, but has since been expanded).

“Augmented books, or a-books, can be the future of many book genres, from travel and tourism to education. This technology exists to assist the reader in a deeper understanding of the written topic and get more through digital means without ruining the experience of reading a paper book.”

Power efficiency and pre-printed conductive paper are some of the new features which allow Surrey’s augmented books to now be manufactured on a semi-industrial scale. With no wiring visible to the reader, Surrey’s augmented reality books allow users to trigger with a simple gesture (such as a swipe of a finger or turn of a page), which will then be displayed on a nearby device.

U.S. oil and gas company Chesapeake Energy has entered into a term gas supply agreement (GSA) with Golden Pass LNG Terminal, a joint venture of QatarEnergy and ExxonMobil.

Under the deal, Chesapeake is to deliver 300 milllion cubic feet per day of gas from Haynesville to Golden Pass’s LNG terminal on the Gulf Coast near Sabine Pass, Texas.

The GSA is to start in 2024 with a 36-month term at an NYMEX-based price less a fixed differential.

Rob Barnett, a senior clean energy analyst for Bloomberg, forecasts a 30% increase in global PV deployment this year, and double-digit growth through 2025.

Demand is pushing solar growth across the world to new heights, as Bloomberg senior analyst Rob Barnett forecasts deployment to increase by 30% this year. Total global solar deployment is closing in on 1 TW installed – an impressive milestone for the energy transition.

“The global solar picture is just staggering at this point,” Barnett told Yahoo Finance. “We are on track to install something like 250 GW of solar capacity this year.”

China is contributing the largest share to capacity growth this year, with about 108 GW of new operational PV. This is a near-doubling of the roughly 55 GW installed by China last year. The country has the world’s largest exposure to renewable energy, with 323 GW of solar and 338 GW of wind energy. President Xi Jinping aims for 1,200 GW combined by 2030, and the nation is currently ahead of schedule on that goal, said Bloomberg.

Wearable electronics, from health and fitness trackers to virtual reality headsets, are part of our everyday lives. But finding ways to continuously power these devices is a challenge.

University of Washington researchers have developed an innovative solution: the first-of-its kind flexible, wearable thermoelectric device that converts to electricity. This device is soft and stretchable, yet sturdy and efficient—properties that can be challenging to combine.

The team published these findings July 24 in Advanced Energy Materials.
