Clean energy jobs energize Pennsylvania: Clean Energy Employment Report

Space solar power promises wireless energy from orbital solar satellites via microwave or laser power beaming, using photovoltaics and rectennas. NRL and AFRL advances hint at 24-7 renewable power delivery to Earth and airborne drones.

Key Points

Space solar power beams orbital solar energy to Earth via microwaves or lasers, enabling continuous wireless electricity.

✅ Harvests sunlight in orbit and transmits via microwaves or lasers

✅ Provides 24-7 renewable power, independent of weather or night

✅ Enables wireless power for remote sites, grids, and drones

Earlier this year, a small group of spectators gathered in David Taylor Model Basin, the Navy’s cavernous indoor wave pool in Maryland, to watch something they couldn’t see. At each end of the facility there was a 13-foot pole with a small cube perched on top. A powerful infrared laser beam shot out of one of the cubes, striking an array of photovoltaic cells inside the opposite cube. To the naked eye, however, it looked like a whole lot of nothing. The only evidence that anything was happening came from a small coffee maker nearby, which was churning out “laser lattes” using only the power generated by the system as ambitions for cheap abundant electricity gain momentum worldwide.

The laser setup managed to transmit 400 watts of power—enough for several small household appliances—through hundreds of meters of air without moving any mass. The Naval Research Lab, which ran the project, hopes to use the system to send power to drones during flight. But NRL electronics engineer Paul Jaffe has his sights set on an even more ambitious problem: beaming solar power to Earth from space. For decades the idea had been reserved for The Future, but a series of technological breakthroughs and a massive new government research program suggest that faraway day may have finally arrived as interest in space-based solar broadens across industry and government.

Since the idea for space solar power first cropped up in Isaac Asimov’s science fiction in the early 1940s, scientists and engineers have floated dozens of proposals to bring the concept to life, including inflatable solar arrays and robotic self-assembly. But the basic idea is always the same: A giant satellite in orbit harvests energy from the sun and converts it to microwaves or lasers for transmission to Earth, where it is converted into electricity. The sun never sets in space, so a space solar power system could supply renewable power to anywhere on the planet, day or night, as recent tests show we can generate electricity from the night sky as well, rain or shine.

Like fusion energy, space-based solar power seemed doomed to become a technology that was always 30 years away. Technical problems kept cropping up, cost estimates remained stratospheric, and as solar cells became cheaper and more efficient, and storage improved with cheap batteries, the case for space-based solar seemed to be shrinking.

That didn’t stop government research agencies from trying. In 1975, after partnering with the Department of Energy on a series of space solar power feasibility studies, NASA beamed 30 kilowatts of power over a mile using a giant microwave dish. Beamed energy is a crucial aspect of space solar power, but this test remains the most powerful demonstration of the technology to date. “The fact that it’s been almost 45 years since NASA’s demonstration, and it remains the high-water mark, speaks for itself,” Jaffe says. “Space solar wasn’t a national imperative, and so a lot of this technology didn’t meaningfully progress.”

John Mankins, a former physicist at NASA and director of Solar Space Technologies, witnessed how government bureaucracy killed space solar power development firsthand. In the late 1990s, Mankins authored a report for NASA that concluded it was again time to take space solar power seriously and led a project to do design studies on a satellite system. Despite some promising results, the agency ended up abandoning it.

In 2005, Mankins left NASA to work as a consultant, but he couldn’t shake the idea of space solar power. He did some modest space solar power experiments himself and even got a grant from NASA’s Innovative Advanced Concepts program in 2011. The result was SPS-ALPHA, which Mankins called “the first practical solar power satellite.” The idea, says Mankins, was “to build a large solar-powered satellite out of thousands of small pieces.” His modular design brought the cost of hardware down significantly, at least in principle.

Jaffe, who was just starting to work on hardware for space solar power at the Naval Research Lab, got excited about Mankins’ concept. At the time he was developing a “sandwich module” consisting of a small solar panel on one side and a microwave transmitter on the other. His electronic sandwich demonstrated all the elements of an actual space solar power system and, perhaps most important, it was modular. It could work beautifully with something like Mankins' concept, he figured. All they were missing was the financial support to bring the idea from the laboratory into space.

Jaffe invited Mankins to join a small team of researchers entering a Defense Department competition, in which they were planning to pitch a space solar power concept based on SPS-ALPHA. In 2016, the team presented the idea to top Defense officials and ended up winning four out of the seven award categories. Both Jaffe and Mankins described it as a crucial moment for reviving the US government’s interest in space solar power.

They might be right. In October, the Air Force Research Lab announced a $100 million program to develop hardware for a solar power satellite. It’s an important first step toward the first demonstration of space solar power in orbit, and Mankins says it could help solve what he sees as space solar power’s biggest problem: public perception. The technology has always seemed like a pie-in-the-sky idea, and the cost of setting up a solar array on Earth is plummeting, as proposals like a tenfold U.S. solar expansion signal rapid growth; but space solar power has unique benefits, chief among them the availability of solar energy around the clock regardless of the weather or time of day.

It can also provide renewable energy to remote locations, such as forward operating bases for the military, which has deployed its first floating solar array to bolster resilience. And at a time when wildfires have forced the utility PG&E to kill power for thousands of California residents on multiple occasions, having a way to provide renewable energy through the clouds and smoke doesn’t seem like such a bad idea. (Ironically enough, PG&E entered a first-of-its-kind agreement to buy space solar power from a company called Solaren back in 2009; the system was supposed to start operating in 2016 but never came to fruition.)

“If space solar power does work, it is hard to overstate what the geopolitical implications would be,” Jaffe says. “With GPS, we sort of take it for granted that no matter where we are on this planet, we can get precise navigation information. If the same thing could be done for energy, especially as peer-to-peer energy sharing matures, it would be revolutionary.”

Indeed, there seems to be an emerging race to become the first to harness this technology. Earlier this year China announced its intention to become the first country to build a solar power station in space, and for more than a decade Japan has considered the development of a space solar power station to be a national priority. Now that the US military has joined in with a $100 million hardware development program, it may only be a matter of time before there’s a solar farm in the solar system.

Atlanta Airport Power Outage disrupts Hartsfield-Jackson as an underground fire cripples switchgear redundancy, canceling flights during holiday travel; Georgia Power restores electricity overnight while utility crews probe causes and monitor system resilience.

Key Points

A major Hartsfield-Jackson blackout from an underground fire; power restored as switchgear redundancy is investigated.

✅ Underground fire near Plane Train tunnel damaged switchgear systems

✅ Over 1,100 flights canceled; holiday travel severely disrupted

✅ Georgia Power restored service; redundancy and root cause under review

Power has been restored at the world’s busiest airport after a massive outage Sunday afternoon left planes and passengers stranded for hours, forced airlines to cancel more than 1,100 flights and created a logistical nightmare during the already-busy holiday travel season.

An underground fire caused a complete power outage Sunday afternoon at Hartsfield-Jackson Atlanta International Airport, resulting in thousands of canceled flights at the world's busiest terminal and affecting travelers worldwide.

The massive outage didn’t just leave passengers stranded overnight Sunday, it also affected travelers with flights Monday morning schedules.

According to Paul Bowers, the president and CEO of Georgia Power,  “From our standpoint, we apologize for the inconvenience,” he said. The utility restored power to the airport shortly before midnight.

Utility Crews are monitoring the fixes that restored power and investigating what caused the fire and why it was able to damage redundant systems. Bowers said the fire occurred in a tunnel that runs along the path of the underground Plane Train tunnel near Concourse E.

Sixteen highly trained utility personnel worked in the passageway to reconnect the network.“Our investigation is going through the process of what do we do to ensure we have the redundancy going back at the airport, because right now we are a single source feed,” Bowers said.

“We will have that complete by the end of the week, and then we will turn to what caused the failure of the switchgear.”

Though the cause isn’t yet known, he said foul play is not suspected.“There are two things that could happen,” he said.

“There are inner workings of the switchgear that could create the heat that caused the fire, or the splicing going into that switchgear -- that the cable had a failure on that going into the switch gear.”

When asked if age of the system could have been a failure, Bowers said his company conducts regular inspections.“We constantly inspect,” he said. “We inspect on an annual basis to ensure the reliability of the network, and that redundancy is protection for the airport.”Bowers said he is not familiar with any similar fire or outage at the airport.

“The issue for us is to ensure the reliability is here and that it doesn’t happen again and to ensure that our network is resilient enough to withstand any kind of fire,” he said. He added that Georgia Power will seek to determine what can be done in the future to avoid a similar event, such as those experienced during regional outages in other communities.

US Utilities Shift From Coal as natural gas stays cheap, renewables like wind and solar scale, Clean Power Plan uncertainty lingers, and investors, state policies, and emissions targets drive generation choices and accelerate retirements.

Key Points

A long-term shift by utilities from coal to cheap natural gas, expanding renewables, and lower-emission generation.

✅ Cheap natural gas undercuts coal on price and flexibility.

✅ Renewables costs falling; wind and solar add competitive capacity.

✅ State policies and investors sustain emissions reductions.

When President Donald Trump signed an executive order last week to sweep away Obama-era climate change regulations, he said it would end America's "war on coal", usher in a new era of energy production and put miners back to work.

But the biggest consumers of U.S. coal - power generating companies - remain unconvinced about efforts to replace Obama's power plant overhaul with a lighter-touch approach.

Reuters surveyed 32 utilities with operations in the 26 states that sued former President Barack Obama's administration to block its Clean Power Plan, the main target of Trump's executive order. The bulk of them have no plans to alter their multi-billion dollar, years-long shift away from coal, suggesting demand for the fuel will keep falling despite Trump's efforts.

The utilities gave many reasons, mainly economic: Natural gas - coal’s top competitor - is cheap and abundant; solar and wind power costs are falling; state environmental laws remain in place; and Trump's regulatory rollback may not survive legal challenges, as rushed pricing changes draw warnings from energy groups.

Meanwhile, big investors aligned with the global push to fight climate change – such as the Norwegian Sovereign Wealth Fund – have been pressuring U.S. utilities in which they own stakes to cut coal use.

"I’m not going to build new coal plants in today’s environment," said Ben Fowke, CEO of Xcel Energy, which operates in eight states and uses coal for about 36 percent of its electricity production. "And if I’m not going to build new ones, eventually there won’t be any."

Of the 32 utilities contacted by Reuters, 20 said Trump's order would have no impact on their investment plans; five said they were reviewing the implications of the order; six gave no response. Just one said it would prolong the life of some of its older coal-fired power units.

North Dakota's Basin Electric Power Cooperative was the sole utility to identify an immediate positive impact of Trump's order on the outlook for coal.

"We're in the situation where the executive order takes a lot of pressure off the decisions we had to make in the near term, such as whether to retrofit and retire older coal plants," said Dale Niezwaag, a spokesman for Basin Electric. "But Trump can be a one-termer, so the reprieve out there is short."

Trump's executive order triggered a review aimed at killing the Clean Power Plan and paving the way for the EPA's Affordable Clean Energy rule to replace it, though litigation is ongoing. The Obama-era law would have required states, by 2030, to collectively cut carbon emissions from existing power plants by 30 percent from 2005 levels. It was designed as a primary strategy in U.S. efforts to fight global climate change.

The U.S. coal industry, without increases in domestic demand, would need to rely on export markets for growth. Shipments of U.S. metallurgical coal, used in the production of steel, have recently shown up in China following a two-year hiatus - in part to offset banned shipments from North Korea and temporary delays from cyclone-hit Australian producers.

RETIRING AND RETROFITTING

Coal had been the primary fuel source for U.S. power plants for the last century, but its use has fallen more than a third since 2008 after advancements in drilling technology unlocked new reserves of natural gas.

Hundreds of aging coal-fired power plants have been retired or retrofitted. Huge coal mining companies like Peabody Energy Corp and Arch Coal fell into bankruptcy, and production last year hit its lowest point since 1978.

The slide appears likely to continue: U.S. power companies now expect to retire or convert more than 8,000 megawatts of coal-fired plants in 2017 after shutting almost 13,000 MW last year, according to U.S. Energy Information Administration and Thomson Reuters data.

Luke Popovich, a spokesman for the National Mining Association, acknowledged Trump's efforts would not return the coal industry to its "glory days," but offered some hope.

"There may not be immediate plans for utilities to bring on more coal, but the future is always uncertain in this market," he said.

Many of the companies in the Reuters survey said they had been focused on reducing carbon emissions for a decade or more while tracking 2017 utility trends that reinforce long-term planning, and were hesitant to change direction based on shifting political winds in Washington D.C.

"Utility planning typically takes place over much longer periods than presidential terms of office," Berkshire Hathaway Inc-owned Pacificorp spokesman Tom Gauntt said.

Several utilities also cited falling costs for wind and solar power, which are now often as cheap as coal or natural gas, thanks in part to government subsidies for renewable energy and recent FERC decisions affecting the grid.

In the meantime, activist investors have increased pressure on U.S. utilities to shun coal.

In the last year, Norway's sovereign wealth fund, the world's largest, has excluded more than a dozen U.S. power companies - including Xcel, American Electric Power Co Inc and NRG Energy Inc - from its investments because of their reliance on coal-fired power.

Another eight companies, including Southern Co and NorthWestern Corp, are "under observation" by the fund.

Wyoming-based coal miner Cloud Peak Energy said it doesn't blame utilities for being lukewarm to Trump's order.

"For eight years, if you were a utility running coal, you got the hell kicked out of you," said Richard Reavey, a spokesman for the company. "Are you going to turn around tomorrow and say, 'Let's buy lots of coal plants'? Pretty unlikely."

Ontario Starlink Contract Cancellation underscores rising tariffs, trade tensions, and retaliation, as SpaceX's Elon Musk loses a rural broadband deal; Ontario pivots to procurement bans, energy resilience, and nuclear power to boost grid independence.

Key Points

Ontario ended a C$100M Starlink deal over U.S. tariffs, prompting a shift to rural broadband alternatives.

✅ Triggered by U.S. tariffs; Ontario adopts retaliatory procurement bans.

✅ Ends plan to connect 15,000 rural homes and businesses with broadband.

✅ Signals push for energy resilience, nuclear power, and grid independence.

In a decisive move, Ontario Premier Doug Ford announced the cancellation of a C$100 million contract with Elon Musk's Starlink, a subsidiary of SpaceX, in direct response to U.S. President Donald Trump's imposition of tariffs on Canadian imports. This action underscores the escalating trade tensions between Canada and the United States, a theme highlighted during Ford's Washington meeting on energy tariffs earlier this month, and highlights Ontario's efforts to safeguard its economic interests.

The now-terminated agreement, established in November, aimed to provide high-speed internet access to 15,000 homes and businesses in Ontario's remote areas. Premier Ford's decision to "rip up" the contract signifies a broader strategy to distance the province from U.S.-based companies amid the current trade dispute. He emphasized, "Ontario won't do business with people hell-bent on destroying our economy."

This move is part of a series of retaliatory measures by Canadian provinces, including Ford's threat to cut electricity exports to the U.S., following President Trump's announcement of a 25% tariff on nearly all Canadian imports, excluding oil, which faces a 10% surcharge. These tariffs, set to take effect imminently, have prompted concerns about potential economic downturns in Canada. In response, Prime Minister Justin Trudeau declared that Canada would impose 25% tariffs on C$155 billion worth of U.S. goods, aiming to exert pressure on the U.S. administration to reconsider its stance.

Premier Ford's actions reflect a broader sentiment of economic nationalism, as he also announced a ban on American companies from provincial contracts until the U.S. tariffs are lifted. He highlighted that Ontario's government and its agencies allocate $30 billion annually on procurement, and reiterated his earlier vow to fire the Hydro One CEO and board as part of broader reforms aimed at efficiency.

The cancellation of the Starlink contract raises concerns about the future of internet connectivity in Ontario's rural regions. The original deal with Starlink was seen as a significant step toward bridging the digital divide, offering high-speed internet to underserved communities. With the contract's termination, the province faces the challenge of identifying alternative solutions to fulfill this critical need.

Beyond the immediate implications of the Starlink contract cancellation, Ontario is confronting broader challenges in ensuring the resilience and independence of its energy infrastructure. The province's reliance on external entities for critical services, such as internet connectivity and energy, has come under scrutiny, as Canada's electricity exports are at risk amid ongoing trade tensions and policy uncertainty.

Premier Ford has expressed a commitment to expanding Ontario's capacity to generate nuclear power as a means to bolster energy self-sufficiency. While this strategy aims to reduce dependence on external energy sources, it presents its own set of challenges that critics argue require cleaning up Ontario's hydro mess before new commitments proceed. Developing nuclear infrastructure requires substantial investment, rigorous safety protocols, and long-term planning. Moreover, the integration of nuclear power into the province's energy mix necessitates careful consideration of environmental impacts and public acceptance.

The concept of "Trump-proofing" Ontario's electricity grid involves creating a robust and self-reliant energy system capable of withstanding external political and economic pressures. Achieving this goal entails diversifying energy sources, including building on Ontario's electricity deal with Quebec to strengthen interties, investing in renewable energy technologies, and enhancing grid infrastructure to ensure stability and resilience.

However, the path to energy independence is fraught with complexities. Balancing the immediate need for reliable energy with long-term sustainability goals requires nuanced policy decisions, including Ontario's Supreme Court challenge to the global adjustment fee and related regulatory reviews to clarify cost impacts. Additionally, fostering collaboration between government entities, private sector stakeholders, and the public is essential to navigate the multifaceted challenges associated with overhauling the province's energy framework.

Ontario's recent actions, including the cancellation of the Starlink contract, underscore the province's proactive stance in safeguarding its economic and infrastructural interests amid evolving geopolitical dynamics. While such measures reflect a commitment to self-reliance, they also highlight the intricate challenges inherent in reducing dependence on external entities. As Ontario charts its course toward a more autonomous future, strategic planning, investment in sustainable technologies, and collaborative policymaking will be pivotal in achieving long-term resilience and prosperity.

Self-healing grid technology automatically reroutes power to reduce outages, speed restoration, and boost reliability during storms like Hurricane Ian in Florida, leveraging smart grid sensors, automation, and grid hardening to support Duke Energy customers.

Key Points

Automated smart grid systems that detect faults and reroute power to minimize outages and accelerate restoration.

✅ Cuts outage duration via automated fault isolation

✅ Reroutes electricity with sensors and distribution automation

✅ Supports storm resilience and faster field crew restoration

As Hurricane Ian made its way across Florida, where restoring power in Florida can take weeks in hard-hit areas, Duke Energy's grid improvements were already on the job helping to combat power outages from the storm.

Smart, self-healing technology, similar to smart grid improvements elsewhere, helped to automatically restore more than 160,000 customer outages and saved nearly 3.3 million hours (nearly 200 million minutes) of total lost outage time.

"Hurricane Ian is a strong reminder of the importance of grid hardening and storm preparedness to help keep the lights on for our customers," said Melissa Seixas, Duke Energy Florida state president. "Self-healing technology is just one of many grid improvements that Duke Energy is making to avoid outages, restore service faster and increase reliability for our customers."

Much like the GPS in your car can identify an accident ahead and reroute you around the incident to keep you on your way, self-healing technology is like a GPS for the grid. The technology can quickly identify power outages and alternate energy pathways to restore service faster for customers when an outage occurs.

Additionally, self-healing technology provides a smart tool to assist crews in the field with power restoration after a major storm like Ian, helping reduce outage impacts and freeing up resources to help restore power in other locations.

Three days after Hurricane Ian exited the state, Duke Energy Florida wrapped up restoration of approximately 1 million customers. This progress enabled the company to deploy more than 550 Duke Energy workers from throughout Florida, as well as contractors from across the country, to help restore power for Lee County Electric Cooperative customers.

Crews worked in Cape Coral and Pine Island, one of the hardest-hit areas in the storm's path, as Canadian power crews have in past storms, and completed power restoration for the majority of customers on Pine Island within approximately one week after arriving to the island.

Prior to Ian in 2022, smart, self-healing technology had helped avoid nearly 250,000 extended customer outages in Florida, similar to Hydro One storm recovery efforts, saving around 285,000 hours (17.1 million minutes) of total lost outage time.

Duke Energy currently serves around 59% of customers in Florida with self-healing capabilities on its main power distribution lines, with a goal of serving around 80% over the next few years.

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.
