Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

Iran Power Outage Protests surge as electricity blackouts, drought, and a looming heat wave spark unrest in Tehran, Shiraz, and more, with chants against leadership, strikes, and sanctions-driven economic pressures mounting.

Key Points

Protests across Iran over blackouts, drought, and economic strain challenge authorities and demand accountability.

✅ Rolling blackouts blamed on drought, heat wave, and surging demand.

✅ Chants target leadership amid strikes and wage, water shortages.

✅ Legitimacy questioned after low-turnout election and sanctions.

There have been protests in a number of cities in Iran amid rising public anger over widespread electricity blackouts.

Videos on social media appeared to show crowds in Shar-e Rey near Tehran, Shiraz, Amol and elsewhere overnight.

Some people can be heard shouting "Death to the dictator" and "Death to Khamenei" - a reference to Supreme Leader Ayatollah Ali Khamenei.

The government has apologised for the blackouts, which it has blamed on a severe drought and high demand.

Elsewhere, similar outages have had political repercussions, as a widespread power outage in Taiwan prompted a minister's resignation earlier this year.

President Hassan Rouhani explained in televised remarks on Tuesday morning that the drought meant most of the country's hydroelectric power plants were not operating, placing more pressure on thermal power plants, and that electricity consumption had surged as people used air conditioning to cope with the intense summer heat.

"I apologise to our dear people who have faced problems and suffering in the past few days and I urge them to co-operate [by cutting their electricity use]. People complain about power outages and they are right," Mr Rouhani said.

A video that has gone viral in recent days shows a woman complaining about the blackouts and corruption at a government office in the northern city of Gorgan and demanding that her comments be conveyed to "higher-ups like Mr Rouhani". "The only thing you have done is forcing hijab on us," she shouts.

The president has promised that the government will seek to resolve the problems within the next two or three weeks.

However, a power sector spokesman warned on Monday that consumption was exceeding the production capacity of Iran's power plants by 11GW, and said a "looming heat wave" could make the situation worse, as seen in Iraq's summer electricity crunch this year.

Iranians have also been complaining about water shortages and the non-payment of wages by some local authorities, while thousands of people working in Iran's oil industry have been on strike over pay and conditions, as officials discuss further energy cooperation with Iraq to ease supply pressures.

There was already widespread discontent at government corruption and the economic hardship caused by sanctions that were reinstated when the US abandoned a nuclear deal with Iran three years ago, even as Iran supplies about 40% of Iraq's electricity through cross-border sales.

Analysts say that after the historically low turnout in last month's presidential election, when more than half of the eligible voters stayed at home, the government is facing a serious challenge to its legitimacy.

Mr Rouhani will be succeeded next month by Ebrahim Raisi, a hard-line cleric close to Ayatollah Khamenei who won 62% of the vote after several prominent contenders were disqualified, while Iran finalizes power grid deals with Iraq to bolster regional ties.

The 60-year-old former judiciary chief has presented himself as the best person to combat corruption and solve Iran's economic problems, including ambitions to transmit electricity to Europe as a regional power hub.

But many Iranians and human rights activists have pointed to his human rights record, accusing him of playing a role in the executions of thousands of political prisoners in the 1980s and in the deadly crackdowns on mass anti-government protests in 2009 and 2019.

US Summer Energy Bills Crisis is driven by record heatwaves, soaring electricity prices, AC cooling demand, energy poverty risks, and LIHEAP relief, straining low-income households, vulnerable seniors, and budgets amid volatile utilities and peak demand.

Key Points

Rising household energy costs from extreme heat, higher electricity prices, and AC demand, straining vulnerable families.

✅ Record heatwaves drive peak electricity and cooling loads

✅ Tiered rates and volatile markets inflate utility bills

✅ LIHEAP aid and cooling centers offer short-term relief

As the sweltering heat of summer continues to grip much of the United States, American households are grappling with a staggering rise in energy bills. The combination of record-breaking temperatures and rising electricity prices is placing an unprecedented financial strain on families, raising concerns about the long-term impact on household budgets and overall well-being.

Record Heat and Energy Consumption

This summer has witnessed some of the hottest temperatures on record across the country. With many regions experiencing prolonged heatwaves, the demand for air conditioning and cooling systems has surged amid unprecedented electricity demand across parts of the U.S. The increased use of these energy-intensive appliances has led to a sharp rise in electricity consumption, which, combined with elevated energy prices, has pushed household energy bills to new heights.

The situation is particularly dire for households that are already struggling financially. Many families are facing energy bills that are not only higher than usual but are reaching levels that are unsustainable, underscoring electricity struggles for thousands of families across the country. This has prompted concerns about the potential for energy poverty, where individuals are forced to make difficult choices between paying for essential services and covering other necessary expenses.

Impact on Low-Income and Vulnerable Households

Low-income households and vulnerable populations are disproportionately affected by these soaring energy costs. For many, the financial burden of high energy bills is compounded by energy insecurity during the pandemic and other economic pressures, such as rising food prices and stagnant wages. The strain of paying for electricity during extreme heat can lead to tough decisions, including cutting back on other essential needs like healthcare or education.

Moreover, the heat itself poses a serious health risk, particularly for the elderly, children, and individuals with pre-existing health conditions. High temperatures can exacerbate conditions such as cardiovascular and respiratory illnesses, making the need for reliable cooling even more critical. For those struggling to afford adequate cooling, the risk of heat-related illnesses and fatalities increases significantly.

Utilities and Energy Pricing

The sharp rise in energy bills can be attributed to several factors, including higher costs of electricity production and distribution. The ongoing transition to cleaner energy sources, while necessary for long-term environmental sustainability, has introduced short-term volatility in energy markets. Additionally, power-company supply chain crises and increased demand during peak summer months have contributed to higher prices.

Utilities are often criticized for their pricing structures, which can be complex and opaque. Some regions, including areas where California electricity bills soar under scrutiny, use tiered pricing models that charge higher rates as energy consumption increases. This can disproportionately impact households that need to use more energy during extreme heat, further exacerbating financial strain.

Government and Community Response

In response to the crisis, various government and community initiatives are being rolled out to provide relief. Federal and state programs aimed at assisting low-income households with energy costs are being expanded. These programs, such as the Low-Income Home Energy Assistance Program (LIHEAP), offer financial assistance to help with utility bills, but demand often outstrips available resources.

Local community organizations are also stepping in to offer support. Initiatives include distributing fans and portable air conditioners, providing temporary cooling centers, and offering financial assistance to help cover energy costs. These efforts are crucial in helping to mitigate the immediate impact of high energy bills on vulnerable households.

Long-Term Solutions and Sustainability

The current crisis highlights the need for long-term solutions to address both the causes and consequences of high energy costs. Investing in energy efficiency and renewable energy technologies can help reduce the overall demand for electricity and lower long-term costs. Improvements in building insulation, the adoption of energy-efficient appliances, and advancements in smart grid technologies to prevent summer power outages are all essential components of a sustainable energy future.

Furthermore, addressing income inequality and supporting economic stability are critical to ensuring that all households can manage their energy needs without facing financial hardship. Policymakers will need to consider a range of strategies, including financial support programs, regulatory reforms, and infrastructure investments, to create a more equitable and resilient energy system.

Conclusion

As American households endure the double burden of extreme summer heat and skyrocketing energy bills, the need for immediate relief and long-term solutions has never been clearer. The current crisis serves as a reminder of the broader challenges facing the nation’s energy system and the importance of addressing both short-term needs and long-term sustainability. By investing in efficient technologies, supporting vulnerable populations, and developing resilient infrastructure, the U.S. can work towards a future where energy costs are manageable, and everyone has access to the resources they need to stay safe and comfortable.

Ukraine Electricity Market Price Caps empower the regulator, the National Commission, to set marginal prices on day-ahead, intraday, and balancing markets, stabilize competition, support thermal plants, and sustain the heating season via green tariff obligations.

Key Points

Regulatory limits set by the National Commission to curb price spikes, ensure competition, and secure heat supply.

✅ Sets marginal prices for day-ahead, intraday, balancing markets

✅ Mitigates collusion risks; promotes effective competition

✅ Ensures TPP operation and heat supply during heating season

The Verkhovna Rada, Ukraine's parliament, has adopted at first reading a draft law that proposes giving the National Commission for State Regulation of Energy and Public Utilities the right to set marginal prices in the electricity market, amid EU market revamp plans that aim to reshape pricing, until 2023.

A total of 259 MPs voted for the document at a parliament meeting on Tuesday, November 12, amid electricity import pressures that have tested the grid, according to an Ukrinform correspondent.

Bill No. 2233 introducing amendments to the law on the electricity market provides for the legislative regulation of the mechanism for fulfilling special obligations for the purchase of electricity at a "green" tariff, preventing the uncontrolled growth of electricity prices due to the lack of effective competition, including recent price-fixing allegations that have raised concerns, ensuring heat supply to consumers during the heating period by regulating the issue of the functioning of thermal power plants in the new electricity market.

It is proposed to introduce respective amendments to the law of Ukraine on the electricity market, alongside steps toward synchronization with ENTSO-E to enhance system stability.

In particular, the draft law gives the regulator the right for the period until July 1, 2023 to set marginal prices on the day-ahead market, the intraday market and the balancing market for each trade zone, reflecting similar EU fixed-price contract initiatives being discussed, and to decide on the obligation for producers to submit proposals (applications) for the sale of electricity on the day-ahead market.

Lawmakers think that the adoption of the bill and empowering the regulator to set marginal prices in the relevant segments of the electricity market will prevent, even as rolling back prices in Europe remains difficult for policymakers, "an uncontrolled increase in electricity prices due to the lack of effective competition or collusion between market players, as well as regulate the issue of the functioning of thermal power plants during the autumn and winter period, which is a necessary prerequisite for providing heat to consumers during the heating period."

The new model of the electricity market was launched on July 1 as the UK weighs decoupling gas and power prices to shield consumers, in accordance with the provisions of the law on the electricity market, adopted in 2017.

BC Hydro COVID-19 Site C updates detail monitoring, self-isolation at the work camp, Northern Health coordination, social distancing, reduced staffing, progress on diversion tunnels, Highway 29 realignment, and public reports to Peace River Regional District.

Key Points

Regular reports on COVID-19 monitoring, isolation protocols, staffing, and Site C work with Northern Health.

✅ Daily updates to Peace River Regional District

✅ Isolation rooms reserved in camp dorms

✅ Construction continues with social distancing

BC Hydro says it will begin giving regular updates to the public and the Peace River Regional District about its monitoring of the coronavirus COVID-19 at Site C, reflecting broader industry alerts such as a U.S. grid warning on pandemic risks.

BC Hydro met with the Peace River Regional District Sunday via phone call to discuss the forthcoming measures.

"We did a make a commitment to provide regular updates to Peace River Regional District member communities on an ongoing basis," said spokesman Dave Conway.

"(It's) certainly one of the things that we heard that they want and we heard that strongly and repeatedly."

Conway said updates could be posted as early as Monday on BC Hydro's website for the project.

As of March 23, there were sixteen people in self-isolation at the work camp just outside Fort St. John. Conway did not know how many of the workers have been tested for the virus, but said there are no confirmed cases on site. Provincial guidelines are being followed, he said.

"If they show any of the following symptoms, so sneezing, sore throat, muscle aches, headaches, coughs, or difficulty breathing, they're isolated for 14 days," Conway said.

"We're being very cautious of our application of the guidelines. We're asking anybody to self isolate if they have any slight symptoms."

BC Hydro has set aside one 30-room dorm at the camp for workers who need to isolate themselves, similar to measures in other jurisdictions where the power industry may house staff on-site to maintain operations, and has another four dorms with another 120 rooms that can be used as necessary. Conway could not immediately say whether additional rooms at hotels or at its apartment block have also been reserved.

There have been  700 workers home since a scale-back in construction was announced on March 18, and more workers are expected to be sent home this week. There were 940 people in camp on March 23, Conway said.

"To put that into perspective, the number of people staying in camp at this time of year, based on previous years, usually averages around 1,700," Conway said.

Brad Sperling, board chair for the Peace River Regional District, said BC Hydro has committed to formulating a strategy over the next few days to keep local government and public informed.

Electoral director Karen Goodings said she was pleased by that, and that it's important to everyone that BC Hydro works with Northern Health and adheres to provincial guidelines.

"The senior governments are critical to what measures will be undertaken not only on the project, including the camp, but also on the rules around transportation of workers and on addressing workplace conduct investigations at other utilities," Goodings wrote in an email.

On Sunday, the Site C leisure bus was seen at Totem Mall with two passengers on board.

Conway said the ongoing use of the shuttle is being monitored and evaluated, and is operating under social distancing and extra cleaning guidelines aligned with public transportation changes that have come under BC Transit.

The bus makes 10 trips per day from the camp, with an average of two passengers per trip, Conway said.

"We still have, of course, people in camp, and it's an opportunity for guests to get out and go for a walk and re-provision themselves for essentials for personal needs," Conway said.

Construction of the river diversion tunnels continues to meet a fall deadline, while work also carries on to realign Highway 29, build the transmission line, and clear the valley and future reservoir. Other site security and environmental monitoring work also continues, as utilities confront a dangerous dam-climbing trend driven by social media.

BC Hydro has said measures have been put into place, amid concerns similar to those voiced by nuclear plant workers about precautions at industrial sites, to minimize the potential spread of the COVID-19 on site, such as closing the camp gym and theatre, eliminating self serve dining stations, as well as non-essential travel, tours, and meetings.

Some workers, however, have raised worries about the tight working conditions on site, noting field safety incidents that highlight risks in the sector.

The province announced Monday 48 new cases in B.C., including one more in the Northern Health region, bringing the region's total to five, while Saskatchewan's numbers show how the crisis has reshaped that province. Their precise whereabouts are not being reported by B.C. public health officials.

BC Hydro Rate Freeze delivers immediate relief on electricity rates in British Columbia, reversing a planned 3% hike, as BCUC oversight, a utility review, and Site C project debates shape provincial energy policy.

Key Points

A one-year provincial policy halting BC Hydro electricity rate hikes while a utility review finds cost savings.

✅ Freeze replaces planned 3% hike approved by BCUC.

✅ Government to conduct comprehensive BC Hydro review.

✅ Critics warn $150M revenue loss impacts capital projects.

British Columbia's NDP government has announced it will freeze BC Hydro rates effective immediately, fulfilling a key election promise.

Energy, Mines and Petroleum Resources Minister Michelle Mungall says hydro rates have gone up by more than 24 per cent in the last four years and by more than 70 per cent since 2001, reflecting proposals such as a 3.75% increase over two years announced previously.

"After years of escalating electricity costs, British Columbians deserve a break on their bills," Mungall said in a news release.

BC Hydro had been approved by the B.C. Utilities Commission to increase the rate by three per cent next year, but Mungall said it will pull back its request in order to comply with the freeze.

In the meantime, the government says it will undertake a comprehensive review of the utility meant to identify cost-savings measures for customers often asked to pay an extra $2 a month on electricity bills.

The Liberal critic, Tracy Redies, says the one year rate freeze is going to cost BC Hydro, calling it a distraction from the bigger issue of the future of the Site C project and the oversight of a BC Hydro fund surplus as well.

"A one year rate freeze costs Hydro $150 million," Redies said. "That means there's $150 million less to invest in capital projects and other investments that the utility needs to make."

"This is putting off decisions that should be made today to the future."

Recommendations from the review — including possible new rates — will be implemented starting in April 2019.
