Huge new offshore wind project approved in U.S.

Posted by in categories: energy, sustainability

The U.S. Department of the Interior has announced its approval of the Revolution Wind project. Located off the coast of Rhode Island, it will supply 704 megawatts (MW) of clean energy, more than 16 times the current offshore wind capacity of the United States.

Currently, the United States has only a small fraction of the world’s offshore wind power. Its first commercial offshore wind farm, near Block Island in the Atlantic, only began operation in 2016, with a nameplate capacity of 30 megawatts (MW). Since then, it has added just 12 MW, for a total of 42 MW.

Energy Vault’s First Grid-Scale Gravity Energy Storage System Is Near Complete

Posted by in categories: energy, materials, robotics/AI

The system is like a solid version of pumped hydro, which uses surplus generating capacity to pump water uphill into a reservoir. When the water’s released it flows down through turbines, making them spin and generate energy.

Energy Vault’s solid gravity system uses huge, heavy blocks made of concrete and composite material and lifts them up in the air with a mechanical crane. The cranes are powered by excess energy from the grid, which might be created on very sunny or windy days when there’s not a lot of demand. The blocks are suspended at elevation until supply starts to fall short of demand, and when they’re lowered down their weight pulls cables that spin turbines and generate electricity.

U.S. Aquifers Are Running Dry, Posing Major Threat to Drinking Water Supply

Posted by in categories: energy, food, law, sustainability

A major _New York Times_ investigation reveals how the United States’ aquifers are becoming severely depleted due to overuse in part from huge industrial farms and sprawling cities. The _Times_ reports that Kansas corn yields are plummeting due to a lack of water, there is not enough water to support the construction of new homes in parts of Phoenix, Arizona, and rivers across the country are drying up as aquifers are being drained far faster than they are refilling. “It can take millions of years to fill an aquifer, but they can be depleted in 50 years,” says Warigia Bowman, director of sustainable energy and natural resources law at the University of Tulsa College of Law. “All coastal regions in the United States are really being threatened by groundwater and aquifer problems.”

Finding Hope In The Dark Power Of Fungus

Posted by in categories: energy, space

Disavowal, though, is not only about waste. The disavowal of dark truths is arguably a theme of modernity itself. Modern practices around death are revealing in this regard: In many traditional societies, a corpse is kept in the family space until its burial; in most modern societies, the dead body is carted off immediately. Embalming is common to halt (and hide) the process of decay. It is precisely this approach that Lee’s mushroom burial suit is critiquing.

From a fungal vantage point, this system is indeed psychotic. Mycoremediation may not be the systemic intervention that was hoped for, but as an expression of one’s personal concern for our toxified landscape, it is far from insignificant. Rather, it is a tangible way for people without much institutional power to engage in the ongoing fight against environmental damage, to try to contain the disasters seeping around us. As a domestic intervention, mycoremediation is modest but culturally meaningful — a method of repair and reconnection.

The power of fungi comes from the proximity they have with dark truths: the abject, the mess we need to face, mortality, vitality, kinship. In other contexts, this proximity elicits wariness, but in our current crisis, it holds the possibility of a healing power — a pharmacological power. Fungi can take on the mess and the junk, break it down and transform and incorporate it rather than ignore it.

Starch discovery unlocks benefits for brewing, baking and milling industries

Posted by in categories: energy, food, health

Research has brought clarity to the longstanding question of how starch granules form in the seeds of Triticeae crops—wheat, barley, and rye—unlocking diverse potential benefits for numerous industries and for human health.

Starch in wheat, maize, rice and potatoes is a vital energy-giving part of our diet and a key ingredient in many industrial applications from brewing and baking to the production of paper, glue, textiles, and construction materials.

Starch granules of different crops vary greatly in size and shape. Wheat starch (and those of other Triticeae) uniquely have two distinct types of granules: large A-type granules and smaller B-type granules.

Research team enhances hydrogen evolution catalyst through stepwise deposition

Posted by in categories: economics, energy, transportation

In order to enhance the accessibility of hydrogen-powered vehicles and establish hydrogen as a viable energy source, it’s imperative to reduce the cost of hydrogen production, thereby achieving economic feasibility. To achieve this goal, maximizing the efficiency of electrolysis-hydrogen evolution, the process responsible for producing hydrogen from water, is crucial.

Recently, a team of researchers comprising Professor In Su Lee, Research Professor Soumen Dutta, and Byeong Su Gu from the Department of Chemistry at Pohang University of Science and Technology (POSTECH) achieved a significant improvement in production efficiency of hydrogen, a green energy source, through the development of a platinum nanocatalyst. They accomplished this feat by depositing two different metals in a stepwise manner.

The findings of their research were published in Angewandte Chemie.

Tesla to provide Virtual Power Plant (VPP) services to Texas grid

Posted by in categories: energy, sustainability

A recent press release from the Public Utility Commission of Texas (PUCT) has revealed that Tesla will be providing Virtual Power Plant (VPP) services to the state’s grid. The program is part of the Aggregate Distributed Energy Resource (ADER) project that the PUCT pushed last year.

With the VPP in place, Texas could now evaluate how consumer-owned small energy devices, such as home battery units, can be virtually aggregated to provide grid-scale services. Similar programs have been launched by Tesla in California and Australia, to much success.

As per the PUCT’s press release, the two ADERs that are launching the initiative involve Tesla Electric customers who have Powerwall batteries in their homes. The participants of the program have agreed to sell their surplus power in the ERCOT market, and will be compensated for doing so. One ADER is comprised of Houston-area CenterPoint Energy customers, while the other is comprised of Dallas-area customers served by Oncor Electric Delivery Company.
