Renewable Energy Breakthroughs drive quantum dots solar efficiency, Air-gen protein nanowires harvesting humidity, and cellulose membranes for flow batteries, enabling printable photovoltaics, 24/7 clean power, and low-cost grid storage at commercial scale.

Key Points

Advances like quantum dot solar, Air-gen, and cellulose flow battery membranes that improve clean power and storage.

✅ Quantum dots raise solar conversion efficiency, are printable

✅ Air-gen harvests electricity from humidity with protein nanowires

✅ Cellulose membranes cut flow battery costs, aid grid storage

Science never sleeps. The quest to find new and better ways to do things continues in thousands of laboratories around the world. Today, the global economy is based on the use of electricity, and one analysis shows wind and solar potential could meet 80% of US demand, underscoring what is possible. If there was a way to harness all the energy from the sun that falls on the Earth every day, there would be enough of electricity available to meet the needs of every man, woman, and child on the planet with plenty left over. That day is getting closer all the time. Here are three reasons why.

Quantum Dots Make Better Solar Panels
According to Science Daily, researchers at the University of Queensland have set a new world record for the conversion of solar energy to electricity using quantum dots — which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device. The solar devices they developed have beaten the existing solar conversion record by 25%.

“Conventional solar technologies use rigid, expensive materials. The new class of quantum dots the university has developed are flexible and printable,” says professor Lianzhou Wang, who leads the research team. “This opens up a huge range of potential applications, including the possibility to use it as a transparent skin to power cars, planes, homes and wearable technology. Eventually it could play a major part in meeting the United Nations’ goal to increase the share of renewable energy in the global energy mix.”

“This new generation of quantum dots is compatible with more affordable and large-scale printable technologies,” he adds. “The near 25% improvement in efficiency we have achieved over the previous world record is important. It is effectively the difference between quantum dot solar cell technology being an exciting prospect and being commercially viable.” The research was published on January 20 in the journal Nature Energy.

Electricity From Thin Air
Science Daily also reports that researchers at UMass Amherst also have interesting news. They claim they created a device called an Air-gen, short for air powered generator. (Note: recently we reported on other research that makes electricity from rainwater.) The device uses protein nanowires created by a microbe called Geobacter. Those nanowires can generate electricity from thin air by tapping the water vapor present naturally in the atmosphere. “We are literally making electricity out of thin air. The Air-gen generates clean energy 24/7. It’s the most amazing and exciting application of protein nanowires yet,” researchers Jun Yao and Derek Lovely say. There work was published February 17 in the journal Nature.

The new technology developed in Yao’s lab is non-polluting, renewable, and low-cost. It can generate power even in areas with extremely low humidity such as the Sahara Desert. It has significant advantages over other forms of renewable energy including solar and wind, Lovley says, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and “it even works indoors,” a point underscored by ongoing grid challenges that slow full renewable adoption.

Yao says, “The ultimate goal is to make large-scale systems. For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid, and in parallel others are advancing bio-inspired fuel cells that could complement such devices. Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production. This is just the beginning of a new era of protein based electronic devices.”

Improved Membranes For Flow Batteries From Cellulose
Storing energy is almost as important to decarbonizing the environment as making it in the first place, with the rise of affordable solar batteries improving integration.  There are dozens if not hundreds of ways to store electricity and they all work to one degree or another. The difference between which ones are commercially viable and ones that are not often comes down to money.

Flow batteries — one approach among many, including fuel cells for renewable storage — use two liquid electrolytes — one positively charged and one negatively charged — separated by a membrane that allows electrons to pass back and forth between them. The problem is, the liquids are highly corrosive. The membranes used today are expensive — more than $1,300 per square meter.

Phys.org reports that Hongli Zhu, an assistant professor of mechanical and industrial engineering at Northeastern University, has successfully created a membrane for use in flow batteries that is made from cellulose and costs just $147.68 per square meter. Reducing the cost of something by 90% is the kind of news that gets people knocking on your door.

The membrane uses nanocrystals derived from cellulose in combination with a polymer known as polyvinylidene fluoride-hexafluoropropylene.  The naturally derived membrane is especially efficient because its cellular structure contains thousands of hydroxyl groups, which involve bonds of hydrogen and oxygen that make it easy for water to be transported in plants and trees.

In flow batteries, that molecular makeup speeds the transport of protons as they flow through the membrane. “For these materials, one of the challenges is that it is difficult to find a polymer that is proton conductive and that is also a material that is very stable in the flowing acid,” Zhu says.

Cellulose can be extracted from natural sources including algae, solid waste, and bacteria. “A lot of material in nature is a composite, and if we disintegrate its components, we can use it to extract cellulose,” Zhu says. “Like waste from our yard, and a lot of solid waste that we don’t always know what to do with.”

Flow batteries can store large amounts of electricity over long periods of time — provided the membrane between the storage tanks doesn’t break down. To store more electricity, simply make the tanks larger, which makes them ideal for grid storage applications where there is often plenty of room to install them. Slashing the cost of the membrane will make them much more attractive to renewable energy developers and help move the clean energy revolution forward.

The Takeaway
The fossil fuel crazies won’t give up easily. They have too much to lose and couldn’t care less if life on Earth ceases to exist for a few million years, just so long as they get to profit from their investments. But they are experiencing a death of a thousand cuts. None of the breakthroughs discussed above will end thermal power generation all by itself, but all of them, together with hundreds more just like them happening every day, every week, and every month, even as we confront clean energy's hidden costs across supply chains, are slowly writing the epitaph for fossil fuels.

And here’s a further note. A person of Chinese ancestry is the leader of all three research efforts reported on above. These are precisely the people being targeted by the United States government at the moment as it ratchets up its war on immigrants and anybody who cannot trace their ancestry to northern Europe. Imagine for a moment what will happen to America when researchers like them depart for countries where they are welcome instead of despised.

Electric Vehicle Adoption Barriers include range anxiety, charging infrastructure, and cost parity; consumer demand, tax credits, lithium-ion batteries, and performance benefits are accelerating EV uptake, pushing SUVs and self-driving tech toward mainstream mobility.

Key Points

They are the key hurdles to mainstream EV uptake: range anxiety, sparse charging networks, and high upfront costs.

✅ Range targets of 300+ miles reduce anxiety and match ICE convenience

✅ Expanded home, work, and public charging speeds adoption

✅ Falling battery costs and incentives drive price parity

The automotive industry is hurtling toward a future that will change transportation the same way electricity changed how we light the world. Electric and self-driving vehicles will alter the automotive landscape forever — it's only a question of how soon, and whether the age of electric cars arrives ahead of schedule.

Like any revolution, this one will be created by market demand.
Beyond the environmental benefit, electric vehicle owners enjoy the performance, quiet operation, robust acceleration, style and interior space. And EV owners like not having to buy gasoline. We believe the majority of these customers will stay loyal to electric cars, and U.S. EV sales are soaring into 2024 as this loyalty grows.

But what about non-EV owners? Will they want to buy electric, and is it time to buy an electric car for them yet? About 25 years ago, when we first considered getting into the electric vehicle business with a small car that had about 70 miles of range, the answer was no. But today, the results are far more encouraging.

We recently held consumer clinics in Los Angeles and Chicago and presented people with six SUV choices: three gasoline and three electric. When we asked for their first choice to purchase, 40% of the Chicago respondents chose an electric SUV, and 45% in LA did the same. This is despite a several thousand-dollar premium on the price of the electric models, and despite that EV sales still lag gas cars nationally today, consumer interest was strong (but also before crucial government tax credits that we believe will continue to drive people toward electric vehicles and help fuel market demand).

They had concerns, to be sure. Most people said they want vehicles that can match gasoline-powered vehicles in range, ease of ownership and cost. The sooner we can break down these three critical barriers, the sooner electric cars will become mainstream.

Range
Range is the single biggest barrier to EV acceptance. Just as demand for gas mileage doesn't go down when there are more gas stations, demand for better range won't ease even as charging infrastructure improves. People will still want to drive as long as possible between charges.

Most consumers surveyed during our clinics said they want at least 300 miles of range. And if you look at the market today, which is driven by early adapters, electric cars have hit an inflection point in demand, and the numbers bear that out. The vast majority of electric vehicles sold — almost 90% — are six models with the highest range of 238 miles or more — three Tesla models, the Chevrolet Bolt EV, the Hyundai Kona and the Kia Niro, according to IHS Markit data.

Lithium-ion batteries, which power virtually all electric cars on the road today, are rapidly improving, increasing range with each generation. At GM, we recently announced that our 2020 Chevrolet Bolt EV will have a range of 259 miles, a 21-mile improvement over the previous model. Range will continue to improve across the industry, and range anxiety will dissipate.

Charging infrastructure
Our research also shows that, among those who have considered buying an electric vehicle, but haven't, the lack of charging stations is the number one reason why.

For EVs to gain widespread acceptance, manufacturers, charging companies, industry groups and governments at all levels must work together to make public charging available in as many locations as possible. For example, we are seeing increased partnership activity between manufacturers and charging station companies, as well as construction companies that build large infrastructure projects, as the American EV boom approaches, with the goal of adding thousands of additional public charging stations in the United States.

Private charging stations are just as important. Nearly 80% of electric vehicle owners charge their vehicles at home, and almost 15% at work, with the rest at public stations, our research shows. Therefore, continuing to make charging easy and seamless is vital. To that end, more partnerships with companies that will install the chargers in consumers' homes conveniently and affordably will be a boon for both buyers and sellers.

Cost
Another benefit to EV ownership is a lower cost of operation. Most EV owners report that their average cost of operation is about one-third of what a gasoline-powered car owner pays. But the purchase price is typically significantly higher, and that's where we should see change as each generation of battery technology improves efficiency and reduces cost.

Looking forward, we think electric vehicle propulsion systems will achieve cost parity with internal combustion engines within a decade or sooner, and will only get better after that, driving sticker prices down and widening the appeal to the average consumer. That will be driven by a number of factors, including improvements with each generation of batteries and vehicles, as well as expected increased regulatory costs on gasoline and diesel engines.

Removing these barriers will lead to what I consider the ultimate key to widespread EV adoption — the emergence of the EV as a consumer's primary vehicle — not a single-purpose or secondary vehicle. That will happen when we as an industry are able to offer the utility, cost parity and convenience of today's internal combustion-based cars and trucks.

To get the electric vehicle to first-string status, manufacturers simply must make it as good or better than the cars, trucks and crossovers most people are used to driving today. And we must deliver on our promise of making affordable, appealing EVs in the widest range of sizes and body styles possible. When we do that, electric vehicle adoption and acceptance will be widespread, and it can happen sooner than most people think.

Enbridge Alberta CCS Project targets carbon capture and storage in Alberta, capturing emissions from industrial emitters to advance net-zero goals, leveraging carbon pricing, regulatory support, and a hub model despite a key partner's exit.

Key Points

A proposed Alberta carbon capture hub by Enbridge to store industrial emissions and support net-zero targets.

✅ Seeks emitters across power, oil and gas, and heavy industry

✅ Backed by carbon pricing, regulation, and net-zero mandates

✅ Faces high capex, storage risk, and anchor-tenant uncertainty

Enbridge Inc., a Canadian energy giant, is digging its heels in on its proposed carbon capture and storage (CCS) project in Alberta. This comes despite the recent withdrawal of Capital Power, a major potential emitter that was expected to utilize the CCS technology. Enbridge maintains the project remains viable, but questions linger about its future viability without a cornerstone anchor.

The CCS project, envisioned as a major carbon capture hub in Alberta, aimed to capture emissions from industrial facilities and permanently store them underground. This technology has the potential to play a significant role in reducing greenhouse gas emissions and mitigating the effects of climate change, alongside grid solutions like bridging the Alberta-B.C. electricity gap that can complement decarbonization efforts.

Capital Power's decision to shelve its $2.4 billion Genesee Generating Station project, which was designed to integrate with the CCS hub, threw a wrench into Enbridge's plans. The Genesee project was expected to be a key source of emissions for capture and storage, and its status is being weighed as Ottawa advances the federal coal plan to phase out unabated coal.

Enbridge, however, remains optimistic. The company cites ongoing discussions with other potential emitters interested in utilizing the CCS technology, amid new funding signals such as the U.S. DOE's $110M for CCUS that highlight momentum. They believe the project holds significant value despite Capital Power's departure.

"We are confident in the long-term viability of the project and continue to actively engage with potential customers," said Enbridge spokesperson Rachel Giroux. "Carbon capture and storage is a critical technology for achieving net-zero emissions, and we believe there is a strong business case for our CCS project."

Enbridge's confidence hinges on several factors. Firstly, they believe there is a growing appetite for CCS technology amongst industrial facilities facing increasing pressure to reduce their carbon footprint. Regulations and carbon pricing mechanisms, including new U.S. EPA power plant rules that test CCS readiness, could further incentivize companies to adopt CCS solutions.

Secondly, Enbridge highlights the potential for capturing emissions from not just power plants but also from other industrial sectors like oil and gas production and clean hydrogen projects in Canada, where reforming processes can generate CO2. This broader application could significantly increase the captured carbon volume and strengthen the project's economic viability.

However, skepticism remains. Critics point to the high upfront costs associated with CCS development and the nascent stage of the technology. They argue that without a guaranteed stream of captured emissions, the project might not be financially sound. Additionally, the long-term safety and effectiveness of large-scale carbon storage solutions remain under scrutiny.

The success of Enbridge's CCS project hinges on attracting new emitters. Replacing Capital Power's contribution will be a significant challenge. Enbridge will need to demonstrate the project's economic viability and navigate the complex regulatory landscape surrounding CCS technology.

The Alberta government's position on CCS is crucial. While the government has expressed support for the technology, the level of financial and regulatory incentives offered will significantly impact investor confidence, especially as the IEA net-zero outlook underscores Canada's need for much more electricity. A clear and stable policy framework will be essential for attracting emitters to the project.

The future of Enbridge's CCS project remains uncertain. Capital Power's withdrawal is a setback, but Enbridge's continued commitment suggests they believe the technology holds promise. Whether they can find enough emitters to justify the project's development will be a critical test. The outcome will have significant implications for the future of CCS technology in Alberta and Canada's broader efforts to achieve net-zero emissions, including Canada-Germany clean energy cooperation that seeks to scale low-carbon fuels.

Tesla Electric UK Expansion signals retail energy entry, leveraging Powerwall VPPs for grid services, dynamic pricing, and energy trading, building on Texas success and Octopus Energy ties to buy and sell electricity automatically.

Key Points

Tesla's plan to launch Tesla Electric in the UK, using Powerwall VPPs to retail energy, trade power, and hedge peaks.

✅ Retail energy model built on Powerwall VPP aggregation

✅ Automated buy-sell arbitrage with dynamic pricing

✅ Leverages prior UK approval and Octopus Energy ties

According to a new job posting, Tesla Electric, Tesla’s new electric utility division, is preparing to expand in the United Kingdom as regions such as California grid planners look to electric vehicles for stability to manage demand.

Late last year, after gaining experience through its virtual power plants (VPPs), including response during California blackouts that pressured the grid, Tesla took things a step further with the launch of “Tesla Electric.”

Instead of reacting to specific “events” and providing services to your local electric utilities through demand response programs, as Tesla Powerwall owners have done in VPPs in California, Tesla Electric is actively and automatically buying and selling electricity for Tesla Powerwall owners – providing a buffer against peak prices.

The company is essentially becoming an energy retailer, aligning with a major future for its energy business envisioned by leadership.

Tesla Electric is currently only available to Powerwall owners in Texas, but the company has plans to expand its products through this new division.

We recently reported on Tesla Electric customers in Texas making as much as $150 a day selling electricity back to the grid through the program.

Now Tesla is looking to expand Tesla Electric to the UK, where grid capacity for rising EV demand remains a key consideration.

The company has listed a new job posting for a role called “Head of Operations, Tesla Electric – Retail Energy.”

This has been in the works for a while now. Tesla used to have a partnership with Octopus Energy in the UK for special electricity rates for its owners, during a period when UK EV inquiries surged amid a fuel supply crisis, but it seemed to be a stepping stone before it would itself become an energy provider in the market.

In 2020, Tesla was officially approved as an electricity retailer in the UK. Now it looks like Tesla is going to use this approval with the launch of Tesla Electric.

Northern Pass Hydropower Project Rehearing faces review by New Hampshire's Site Evaluation Committee as Eversource seeks approval for a 192-mile transmission line, citing energy cost relief, while Massachusetts eyes Central Maine Power as an alternative.

Key Points

A review of Eversource's halted NH transmission plan, weighing impacts, costs, and alternatives.

✅ SEC denied project, Eversource seeks rehearing

✅ 192-mile line to bring Canadian hydropower to NE

✅ Alternative bids include Central Maine Power corridor

Groups supporting and opposing the Northern Pass hydropower project in New Hampshire filed statements Friday in advance of a state committee’s meeting next week on whether it should rehear the project.

The Site Evaluation Committee rejected the transmission proposal last month over concerns about potential negative impacts. It is scheduled to deliberate Monday on Eversource’s request for a rehearing.

The $1.6 billion project would deliver hydropower from Canada, including Hydro-Quebec exports, to customers in southern New England through a 192-mile transmission line in New Hampshire.

If the Northern Pass project fails to ultimately win New Hampshire approval, the Massachusetts Department of Energy Resources has announced it will begin negotiating with a team led by Central Maine Power Co. for a $950 million project through a 145-mile Maine transmission line as an alternative.

Separately, construction later began on the disputed $1 billion electricity corridor despite ongoing legal and political challenges.

The Business and Industry Association voted last month to endorse the project after remaining neutral on it since it was first proposed in 2010. A letter sent to the committee Friday urges it to resume deliberations. The association said it is concerned about the severe impact the committee’s decision could have on New Hampshire’s economic future, even as Connecticut overhauls electricity market structure across New England.

“The BIA believes this decision was premature and puts New Hampshire’s economy at risk,” organization President Jim Roche wrote. “New Hampshire’s electrical energy prices are consistently 50-60 percent higher than the national average. This has forced employers to explore options outside New Hampshire and new England to obtain lower electricity prices. Businesses from outside New Hampshire and others now here are reversing plans to grow in New Hampshire due to the Site Evaluation Committee’s decision.”

The International Brotherhood of Electrical Workers and the Coos County Business and Employers Group also filed a statement in support of rehearing the project.

The Society to Protect New Hampshire Forests, which is opposed to the project, said Eversource’s request is premature because the committee hasn’t issued a final written decision yet. It also said Eversource hasn’t proven committee members “made an unlawful or unreasonable decision or mistakenly overlooked matters it should have considered.”

As part of its request for reconsideration, Eversource said it is offering up to $300 million in reductions to low-income and business customers in the state.

It also is offering to allocate $95 million from a previously announced $200 million community fund — $25 million to compensate for declining property values, $25 million for economic development and $25 million to promote tourism in affected areas. Another $20 million would fund energy efficiency programs.

IAEA Nuclear Reactor Simulators enable virtual nuclear power plant training on IPWR/PWR systems, load-following operations, baseload dynamics, and turbine coupling, supporting advanced reactor education, flexible grid integration, and low-carbon electricity skills development during remote learning.

Key Points

IAEA Nuclear Reactor Simulators are tools for training on reactor operations, safety, and flexible power management.

✅ Simulates IPWR/PWR systems with real-time parameter visualization.

✅ Practices load-following, baseload, and grid flexibility scenarios.

✅ Supports remote training on safety, controls, and turbine coupling.

Students and professionals in the nuclear field are making use of learning opportunities during lockdown made necessary by the Covid-19 pandemic, drawing on IAEA low-carbon electricity lessons for the future.

Requests to use the International Atomic Energy Agency’s (IAEA’s) basic principle nuclear reactor simulators have risen sharply in recent weeks, IAEA said on 1 May, as India takes steps to get nuclear back on track. New users will have the opportunity to learn more about operating them.

“This suite of nuclear power plant simulators is part of the IAEA education and training programmes on technology development of advanced reactors worldwide. [It] can be accessed upon request by interested parties from around the world,” said Stefano Monti, head of the IAEA’s Nuclear Power Technology Development Section.

Simulators include several features to help users understand fundamental concepts behind the behaviour of nuclear plants and their reactors. They also provide an overview of how various plant systems and components work to power turbines and produce low-carbon electricity, while illustrating roles beyond electricity as well.

In the integral pressurised water reactor (IPWR) simulator, for instance, a type of advanced nuclear power design, users can navigate through several screens, each containing information allowing them to adjust certain variables. One provides a summary of reactor parameters such as primary pressure, flow and temperature. Another view lays out the status of the reactor core.

The “Systems” screen provides a visual overview of how the plant’s main systems, including the reactor and turbines, work together. On the “Controls” screen, users can adjust values which affect reactor performance and power output.

This simulator provides insight into how the IPWR works, and also allows users to see how the changes they make to plant variables alter the plant’s operation. Operators can also perform manoeuvres similar to those that would take place in the course of real plant operations e.g. in load following mode.

“Currently, most nuclear plants operate in ‘baseload’ mode, continually generating electricity at their maximum capacity. However, there is a trend of countries, aligned with green industrial revolution strategies, moving toward hybrid energy systems which incorporate nuclear together with a diverse mix of renewable energy sources. A greater need for flexible operations is emerging, and many advanced power plants offer standard features for load following,” said Gerardo Martinez-Guridi, an IAEA nuclear engineer who specialises in water-cooled reactor technology.

Prospective nuclear engineers need to understand the dynamics of the consequences of reducing a reactor’s power output, for example, especially in the context of next-generation nuclear systems and emerging grids, and simulators can help students visualise these processes, he noted.

“Many reactor variables change when the power output is adjusted, and it is useful to see how this occurs in real-time,” said Chirayu Batra, an IAEA nuclear engineer, who will lead the webinar on 12 May.

“Users will know that the operation is complete once the various parameters have stabilised at their new values.”

Observing and comparing the parameter changes helps users know what to expect during a real power manoeuvre, he added.
