Iberdrola teams up with AECOM to create Italian railway powered by green hydrogen

2021-08-31T16:59:00-04:00

Spanish utility company Iberdrola has announced that a memorandum of understanding (MOU) has been signed, with signatories including AECOM, for a project to convert Italy’s historic Apennine railway into one powered by green hydrogen.

Other members of the agreement include Italian sustainable developer Ancitel Energia e Ambiente and Italian hydrogen company Cinque International. Funded by the European Clean Hydrogen Alliance, the project aims to replace defunct diesel locomotives with green hydrogen-powered ones. This switch will be a “drastically less expensive alternative” to traditional electrification, says Iberdrola. The company also claims that this will bring “innovation and development” to areas impacted by depopulation and deindustrialization due to earthquakes in 2009, 2016, and 2017.

The more than 186-mile-long railway line will connect inland areas of Italy, running through four central Italian regions. The MOU also includes an evaluation of the technical viability to ...

California poised to ramp up its geothermal capacity

2020-01-28T16:21:00-05:00

After years of playing third fiddle to solar and wind power, geothermal energy is poised to start growing again in California. [...] The new plants will be the first geothermal facilities built in California in nearly a decade — potentially marking a long-awaited turning point for a technology that could play a critical role in the state’s transition to cleaner energy sources.

The Los Angeles Times on California's efforts to increase, potentially double, the share geothermal energy contributes to the state's electricity mix by adding new plants.

Traditionally, the much higher upfront cost of geothermal plants (compared to solar or wind farms of comparable capacity) outplayed the technology's big advantage of generating dependable emission-free, renewable electricity regardless of weather conditions above ground.

With more plants going on line in coming years, hopes are that kilowatt-hour prices of geothermal-generated electricity will drop enough to help California reach its ambitious goal of 100% renewable-powered energy by 2045.

World's biggest nuclear fusion project completes civil engineering work on Tokamak Building

2019-11-13T15:29:00-05:00

A Vinci-led consortium [...] completed civil engineering works on the high-spec building that will house the world’s largest fusion machine, called a “tokamak”, which scientists hope will start replicating the sun’s energy by the middle of the next decade. [...] The 73-metre-high, 120-metre-wide structure required highly specific concretes. Teams developed about 10 formulations to shield staff and the environment from fusion-generated radiation.

Building a tokamak machine to exploit fusion energy similar to our sun is no simple engineering feat: the building will house reactions that happen at extremely high temperatures, around 150 million degrees Celsius, fusing hydrogen nuclei when they reach the plasma state, thus releasing enormous amounts of energy in the process.

ITER, the international organization tasked with operating and subsequently dismantling the experimental facility, hopes to maintain its ambitious First Plasma target in 2025.

"Some parts of the Tokamak Building also called for steel reinforcement density rarely used on projects on this scale (up to 10 times the density of an apartment building wall)," explains a statement released by French contracting giant VINCI.

"[...] access to the heart of the Tokamak Building required customized production of 46 heavy nuclear doors. Each 70-tonne door is manufactured in Germany, brought to the site, filled with concrete and assembled in the hea...

UCLA electrical engineer builds thermoelectric device that can harvest energy after dark

2019-09-18T15:00:00-04:00

[Dr. Raman's] prototype device employs radiative cooling, the phenomenon that makes buildings and parks feel cooler than the surrounding air after sunset. As Dr. Raman’s device releases heat, it does so unevenly, the top side cooling more than the bottom. It then converts the difference in heat into electricity.

After driving through a dark village in Sierra Leone, UCLA electrical engineer Aaswath Raman got the idea of building a device that didn't have to rely on solar power or wind to generate electricity after dark.

Dr. Raman and his research team did just that, and built a prototype thermoelectric device that uses radiative cooling techniques. It doesn't generate much power yet and still has a long way to go in research and development, but other academics like MIT materials scientist Jeffrey C. Grossman tell The New York Times that Dr. Raman's work is one promising step forward in the development of low-power applications at night.

Power companies take the pledge to deliver carbon-free electricity — one fossil-fueled plant at a time

2019-08-02T14:02:00-04:00

New Jersey's largest and oldest power company is pledging to deliver carbon-free electricity to fight climate change. To get there, the power company is shutting down its coal plants, betting big on offshore wind and working hard to keep its existing nuclear plant alive. PSEG said it won't build or acquire any new fossil-fueled power plants, including those running on dirt-cheap natural gas.

Announced in July, one of the oldest power companies in the U.S. is taking the next step towards addressing their involvement in battling climate change. The New Jersey power company PSEG has used fossil fuels to power their plants for the last 116 years. As the oldest power company in America, their initiatives to make changes addressing their plants' carbon emissions is a big step.

According to CNN, "To get there, the power company is shutting down its coal plants, betting big on offshore wind and working hard to keep its existing nuclear plant alive. PSEG said it won't build or acquire any new fossil-fueled power plants, including those running on dirt-cheap natural gas."

PSEG is not the only company to address these issues on climate change. Companies like Xcel Energy, formerly a coal-first company, is making moves to provide zero-carbon electricity by the year 2050. Although the Trump administration has made efforts to save the coal industry by promoting fossil fuels and cutti...

Elizabeth Warren proposes "Green Marshall Plan"

2019-06-04T14:33:00-04:00

On Tuesday, the Warren campaign released its most comprehensive climate plan yet, a $2 trillion package that commits the federal government to spend $150 billion a year over the next decade on low-carbon technology, increases energy research funding tenfold and funds a $100 billion Green Marshall Plan to aid the poorer countries projected to suffer the worst as global temperatures rise.

In specifically identifying a post-World War II-style Marshall Plan-like aid package aimed at assisting international countries lower their carbon emissions, Warren's plan seeks to go further than the other Green New Deal-style visions put forward by competing presidential candidates.

In a Medium post announcing the plan, Warren writes: “The climate crisis demands immediate and bold action. Like we have before, we should bank on American ingenuity and American workers to lead the global effort to face down this threat — and create more than a million good jobs here at home.”

Warren's plan includes the creation of a new "federal office dedicated to selling American-made clean, renewable, and emission-free energy technology abroad and a $100 billion commitment to assisting countries to purchase and deploy this technology." The effort, according to the Massachusetts senator, would help to address global carbon emissions that will need to be eliminated after the US reaches net-zero car...

How a small, conservative Texas town became a key player in the renewable energy revolution

2018-04-20T14:33:00-04:00

Georgetown (pop. 67,000) last year became the largest city in the United States to be powered entirely by renewable energy. Previously, the largest U.S. city fully powered by renewables was Burlington, Vermont (pop. 42,000), home to Senator Bernie Sanders, the jam band Phish and the original Ben & Jerry’s. Georgetown’s feat is all the more dramatic because it demolishes the notion that sustainability is synonymous with socialism and GMO-free ice cream.

In his piece for Smithsonian Magazine, Dan Solomon tells the story of Georgetown, TX's green energy transformation and its unexpected champion, Republican mayor Dale Ross—who is now friends with Al Gore and was even featured in his An Inconvenient Sequel documentary.

Carbon-free nuclear fusion power within reach, according to MIT

2018-03-09T13:55:00-05:00

The dream of nuclear fusion is on the brink of being realised, according to a major new US initiative that says it will put fusion power on the grid within 15 years. The project, a collaboration between scientists at MIT and a private company, will take a radically different approach to other efforts to transform fusion from an expensive science experiment into a viable commercial energy source.

Potentially an inexhaustible and carbon-free source of energy, the dream of making fusion power commercially viable appears to be getting a lot closer, according to a new announcement from researchers at MIT this morning.

"Fusion is the true energy source of the future, as it is completely sustainable, does not release emissions or long-term waste, and is potentially inexhaustible," said Claudio Descalzi, CEO of Italian energy company Eni which is currently collaborating with MIT on the project. "It is a goal that we are increasingly determined to reach quickly."

The research team is confident to have a first working reactor up and running within 15 years.

Apple's investment plan promises 20,000 jobs and a new campus

2018-01-18T19:32:00-05:00

Apple expects to invest over $30 billion in capital expenditures in the US over the next five years and create over 20,000 new jobs through hiring at existing campuses and opening a new one. Apple already employs 84,000 people in all 50 states. The company plans to establish an Apple campus in a new location, which will initially house technical support for customers. The location of this new facility will be announced later in the year.

Apple recently released plans to invest $350 billion in the US economy and create 20,000 jobs over the next 5 years. The company is also planning on building a new campus at a currently unknown location. Adding to the suspense of Amazon's new headquarters, US cities will now have a chance at scoring either of these powerhouses.

Supporting American manufacturing innovation, Apple is also increasing the size of their Advanced Manufacturing Fund from $1 billion to $5 billion.

Renewable energy is also on the company's agenda. In keeping with all US Apple facilities, the recently announced new campus will also be powered entirely by green energy.

How solar battery storage will affect microgrids and off-grid living

2017-08-14T17:32:00-04:00

In March, Tesla cut the ribbon on this groundbreaking grid-scale battery installation, a key test of the viability of energy storage in making renewable energy a more reliable part of the grid. With 50,000 solar panels and 272 batteries, the combined solar-and-storage plant provides enough energy to power 4,500 homes for four hours. If Tesla can help keep Kauai solar-powered around the clock with its batteries, then it can apply what it has learned elsewhere in the country, and around the world

In her Longreads/Grist piece, author Amelia Urry explains the changing nature of solar power challenges that off-grid dwellers as well as smaller, geographically isolated microgrids face now that battery storage on an industrial scale is becoming more lucrative.

The article tells the story of a young couple struggling to live off the grid on the Hawaiian island of Kauai, when at the same time, the local utility cooperative switches on its brand-new bank of Tesla batteries to store the abundant solar power it generates during daytime but couldn't offer during peak times in the early morning and late evening hours: "It’s not about getting off the grid. It’s about building a better one."

Tesla's 'Tiny House' goes on roadshow to promote its solar tech

2017-08-14T14:19:00-04:00

Tesla revealed today that it created what it calls the ‘Tesla Tiny House’ to feature its energy products, like solar panels and Powerwall. The company is bringing the house on tour using a Model X “to educate the public on how to generate, store and use renewable energy for their home.” The tiny house contains a Tesla mobile design studio and configurator to help home owners configure a solar plus energy storage system for their home.

Needless to add that the Tesla Tiny House itself gains all its electricity via a solar installation on the tiny roof.

The exhibition tour is limited to four major Australian cities for now, but the economic gain could be far from tiny — as the world's leader in capita penetration of rooftop solar installations (15% of households / 1.5 million households), Australia is a highly lucrative market for Tesla even though it hasn't started selling solar panels there.

IKEA starts selling home battery storage with its solar panels

2017-08-03T14:18:00-04:00

Ikea is now offering solar panels and home batteries to its customers in the UK. The Scandinavian furniture chain is partnering with solar firm Solarcentury for the venture, with prices for solar battery storage starting at £3,000 (about $3,970 USD). The home batteries are designed to work with existing solar panels, or as part of a new combined home solar panel / battery storage system that Ikea is selling.

The Swedish furniture retail giant first starting solar panels in the UK back in 2013 to grow on a (then) heavily subsidized green energy market but ceased sales in 2015 when the British government announced its plans of cutting solar subsidies by up to 90%. Just a few months later, IKEA returned with a new lineup of home solar panels, this time partnering up with the firm SolarCentury.

"An average solar home in the UK will typically consume around 40% of all the solar electricity generated, or even less if they are regularly out during the day," IKEA explains in a new statement. "The remaining 60% of unused solar electricity is sent back to the National Grid, at a loss compared to its value. This means that homeowners currently lose out on making further cost savings. By adding Solar Battery Storage, unused solar electricity can be stored and used at a later time, meaning the amount of solar electricity an average home can use doubles to 80%."

With the launch of its Solar Battery S...

Google's Dandelion startup wants to make geothermal energy more affordable for homeowners

2017-07-10T14:49:00-04:00

Google parent Alphabet is spinning off a little-known unit working on geothermal power called Dandelion, which will begin offering residential energy services. [...] Dandelion chief executive Kathy Hannun said her team had been working for several years "to make it easier and more affordable to heat and cool homes with the clean, free, abundant, and renewable energy source right under our feet," and that the efforts culminated with the creation of an independent company outside of Alphabet.

"In the U.S., buildings account for 39% of all carbon emissions, mostly from the combustion of fossil fuels for heating and cooling," Dandelion CEO Kathy Hannun explains on the company's blog. "In the Northeast, heating and cooling is particularly carbon-intensive due to the relatively high use of fuel oil or propane as a heating fuel. This also leads to unpredictable costs for homeowners; if fuel prices rise during a particularly long and cold winter, their wallets take a hit."

Hannun describes how designing a better drill was the key to reducing cost, time, hassle, and environmental impact of the drilling process: "After months of testing, we hit upon a design for a fast, slender drill that hit our objectives. It could drill just one or two deep holes just a few inches wide, and compared to typical installation rigs, it produced less waste and took up much less space as it operated. It left a typical suburban backyard relatively undisturbed, so we could minimize landscaping costs ...

Vancouver is the latest city to announce 100% green energy goals

2015-04-10T21:13:00-04:00

Vancouver has become the latest city to commit to running on 100% renewable energy...The city’s ambition is to be the world’s greenest city by 2020 despite the fact Canada has had one of 'the most environmentally irresponsible national governments' for the last 10 years, [said Vancouver deputy mayor Andrea Reimer.]

Which city will be next? Which will pull through? According to The Guardian, Vancouver is one of the latest to join the more than 50 cities that have already announced their plans to run on 100% renewable energy, including San Diego, San Francisco, Sydney, and Copenhagen.

First Texas town makes longterm plans to switch to solar and wind energy

2015-03-30T20:45:00-04:00

Because of its size and intense radiation, Texas leads the nation in solar energy potential, but the solar industry has long struggled to get a foothold in the state... and solar energy currently makes up a tiny percentage of the state’s energy portfolio. That’s beginning to change. Improving technology has driven down the price of solar power, making it more competitive with other resources — even without incentives, developers say.

The municipal utility of Georgetown, a Texan city of about 55,000, recently signed a 25-year contract with SunEdison to buy 150 megawatts of solar power as well as 144 megawatts of wind power from the EDF Renewables wind farm through 2039 -- reportedly being the first city-owned utility to take action on such a plan (and not long after the end of former Texas governor Rick Perry's tenure). While eco-conscious benefits were taken into account, Georgetown signed the deal primarily for financial reasons.

A New Use for the Eiffel Tower

2015-02-25T18:07:00-05:00

While hard to imagine today, Paris’s most iconic monument was largely reviled when it was first built for the 1889 World’s Fair. On February 14, 1887, as construction was just beginning, a group of some of most notable Parisian artists, writers, architects and intellectuals – including Charles Garnier, Émile Zola, Alexandre Dumas fils, and Guy de Maupassant – launched a petition against the Eiffel Tower. "We, the writers, painters, sculptors, architects and lovers of the beauty of Paris, do protest with all our vigour and all our indignation, in the name of French taste and endangered French art and history, against the useless and monstrous Eiffel Tower,” their statement read.

Today, concerns over the use-value of the most-visited paid monument in the world seem comical. But throughout its history, the question of utility has been central to conversations about the Eiffel Tower. Gustave Eiffel, the engineer who designed the 906 ft. tall structure, defensively touted it’s scientific ...
