Massachusetts seeking bids for largest renewable energy contract in New England history

Massachusetts is now reviewing proposals to bring clean energy to the state.

Gov. Charlie Baker’s administration is seeking project bids worldwide to provide up to 1,200 megawatts of energy.

The governor is taking proposals from water, wind, and solar power companies, with local businesses looking to grab the largest renewable energy contract in New England history.

Other proposals from energy companies come from near and far, including Massachusetts and Rhode Island, as well as Vermont, Maine, Indianapolis, Canada and even the United Kingdom.

One familiar company is making a run for the contract: Rhode Island-based Deepwater Wind. They’re known for their first off-shore wind farm in the United States, right off Block Island.

Deepwater Wind shared their proposal with NBC 10 News on Tuesday.

“What we’ve proposed is the largest wind-battery combined power in the world,” CEO Jeff Grybowski said.

Grybowski plans to add 18 to 24 wind turbines about 20 miles off the coast of New Bedford — and they’re planning on to partner with an industry power-player: Tesla

Tesla’s new battery technology will store wind farm energy. The company’s founder, Elon Musk, recently visited Rhode Island

“So, it really helps us maximize the value of all that wind power,” said Grybowski.

The wind-farm energy could power about 80,000 Massachusetts households every year.

“But again, this a price competition,” said Grybowski.

The project, if approved, would be ready by 2023 to 2024.

NBC 10 asked Grybowski how many years it would take to bring the cost down for residents because of the initial investment.

“I think from day one, we think this will be a price-competitive project,” said Grybowski.

He also said it’s likely the wind-turbines won’t be seen from shore.

Deepwater Wind is hoping their off-shore wind farm will be a part of that mix for years to come.

It’s also unlikely any of the project bids will be subsidized.

Exciting new material uses solar energy to remove man-made dye pollutants from water

A novel composite material has been developed by scientists in the Energy Safety Research Institute (ESRI) at Swansea University which shows promise as a catalyst for the degradation of environmentally-harmful synthetic dye pollutants, which are released at a rate of nearly 300,000 tonnes a year into the world’s water.

This novel, non-hazardous photocatalytic material effectively removes dye pollutants from water, adsorbing more than 90 % of the dye and enhancing the rate of dye breakdown by almost ten times using visible light.

The researchers, led by Dr. Charles W. Dunnill and Dr. Daniel Jones at the Energy Safety Research Institute in Swansea University, reported their discovery in the Nature open access journal Scientific Reports.

By heating the reaction mixture at high pressures inside a sealed container, the composite is synthesized by growing ultra-thin “nanowires” of tungsten oxide on the surface of tiny particles of tantalum nitride. As a result of the incredibly small size of the two material components – both the tantalum nitride and tungsten oxide are typically less than 40 billionths of a metre in diameter – the composite provides a huge surface area for dye capture.

The material then proceeds to break the dye down into smaller, harmless molecules using the provided by sunlight, in a process known as “photocatalytic degradation”. Having removed the harmful dyes, the catalyst may simply be filtered from the cleaned water and reused.

While the photocatalytic degradation of dyes has been investigated for several decades, it is only relatively recently that researchers have developed materials capable of absorbing the visible part of the solar spectrum – other materials, such as titanium dioxide, are also able to break down dyes using solar energy, but their efficiency is limited as they only absorb higher energy, ultra-violet light. By making use of a much greater range of the spectrum, materials such as those used by the ESRI team at Swansea University team are able to remove pollutants at a far superior rate.

Both of the materials used in the study have attracted significant interest in recent years. Tungsten oxide, in particular, is considered one of the most promising materials for a range of photocatalytic applications, owing to its high electrical conductivity, chemical stability and surface activity, in addition to its strong light absorbance. As a low band-gap semiconductor, tantalum nitride is red in colour due to its ability to absorb almost the entire spectrum of , and therefore extracts a high amount of energy from sunlight to power the degradation processes.

However, the true potential of the two materials was only realised once they were combined into a single composite. Due to the exchange of electrons between the two materials, the test dye used within the study was broken down by the composite at around double the rate achieved by tantalum nitride on its own, while alone was shown to be incapable of dye degradation. In contrast to other leading photocatalytic materials, many of which are toxic to both humans and aquatic life, both parts of the composite are classed as non-hazardous .

The scientists responsible for the study believe that their research provides just a taster of the material’s potential. “Now that we’ve demonstrated the capabilities of our composite, we aim to not just improve on the material further, but to also begin work on scaling up the synthesis for real-world application.” said Dr. Jones. “We’re also exploring its viability in other areas, such as the photocatalysed splitting of water to generate hydrogen.”

Summer Movie Night: WALL-E is an adorable way to teach kids (and adults) about environmentalism!

Animation. Cutesy romantic plot line. Futuristic setting. Feel-good ending- this movie is set up as something entertaining for the kids to watch, but ends up being just as engaging for every age. Then again, as a movie produced by Disney & Pixar, that’s about par. Yet the message is rather unique for their style of movies; instead of focusing on anthropomorphic animals and friendly human companions, or kids off on an adventure, or the major plot point centering around love and family, this film focuses on something else entirely.

There’s not much dialogue in WALL-E, and it was originally planned to have next to none. This makes sense when you consider that the movie centers around non-speaking robots who communicate largely on noises, movement, expressions, and perhaps a few “words” that rely on intonation instead of conversation or sentence pattern. But it’s the human subplot that really stops to make you think. Humanity as a whole are the villains at the movie’s start, as they’ve littered so much on Earth that there’s no space or resources left to live on, and now subside in a spaceship where they no longer need to walk thanks to technology and have all become obese and trapped behind screens due to their lifestyles. Now i’m not dissing technology (I can only write and publish this article thanks to modern miracles such as wifi), but to become so dependent upon it as to physically atrophy and to no longer even walk by oneself is quite the situation. And the humans in this movie use technology as an escape- deserting Earth without really knowing if or when it will be inhabitable again, and living in ignorant bliss- sound familiar at all?

Amongst robot antics, the movie ends on a happy note, with humanity reconnecting with nature and with each other sans technology and sand disregard for their home; but on a realistic scale, the happy end wouldn’t hasten to arrive. It may not be our future, or even our kids’ future, but we are headed down a path not dissimilar to that portrayed for humanity in the movie. The sooner we take action, the less of an inevitability this path becomes and the better of a chance we have to preserve what little nature we have left, instead of losing it all entirely. But that’s more my musings than the movie; Pixar keeps things colorful and optimistic, and I love this film for the sense of hope it instills even in the face of such a self-made future.
