U.S. to work with allies to secure electric vehicle metals

Microgrid solar outage algorithms optimize renewable energy during blackouts using grid-forming inverters, islanding control, demand forecasting, and energy storage from batteries and EVs, improving reliability by up to 35% for resilient power sharing.

Key Points

Algorithms that island homes, forecast demand, and prioritize critical loads using storage and grid-forming inverters.

✅ Disconnects inverters to form resilient neighborhood microgrids

✅ Forecasts solar, wind, and demand; allocates energy fairly

✅ Uses EVs and batteries; boosts reliability by up to 35%

Some people who have solar panels on their roof are under the impression that they can use them to power their home in the case of an outage, but that simply is not the case. Homes do remain connected to the grid during outages, as U.S. power outage risks grow, but the devices tasked with managing solar panels are normally turned off due to safety concerns. This permanent grid connection essentially prevents homeowners from drawing on the power that their own renewable energy resources generate.

This could be about to change, however, thanks to the efforts of a team of University of California San Diego engineers who have come up with algorithms that would enable homes to share and use their power in outages by disconnecting solar inverters from the grid. Their algorithms work with the existing technology and would have the added benefit of boosting the system’s reliability by as much as 35 percent.

The genius of their work lies in the ability of the algorithm to prioritize the distribution of power from the renewable resources in outages. Their equation considers forecasts for wind and solar power generation to address clean energy intermittency challenges and the available energy storage, including batteries and electric vehicles. It combines this information with the projected energy usage of residents and the amount of energy the homes are able to produce. It can be programmed to prioritize in several different ways, the most vital of which is by favoring those who need power urgently, such as those using life support equipment. It could also prioritize those who are willing to pay extra or reward those who typically generate an energy surplus during normal operations.

Learning lessons from past outages

Lead author Abdulelah H. Habib said the engineers were inspired to find a way to use the renewable power in outages by the events of Hurricane Sandy. This storm affected more than eight million people on the nation’s East Coast, some of whom were left without power for as long as two weeks.

According to the researchers, most customers prefer sharing community-scale storage systems over having systems in each home because of the lower costs. One of the paper’s senior authors, Raymond de Callafon, said that homes that are connected together are not only more resilient in power outages but they also happen to be more resilient to price fluctuations.

Each home needs to be equipped with special circuit breakers that can be remotely controlled, while utilities would need to install some communications methods so the power systems within a particular residential cluster can communicate amongst themselves. They also need a “grid forming inverter” to help them connect to one another and manage excess solar on networks safely.

One stumbling block that will have to be overcome is the current regulations. Most states do not allow individual homeowners to sell power to other homeowners, so there would have to be some adjustments to make this a reality.

Solar power growing in popularity

Solar power’s popularity is currently on the rise, and reductions in cost as the technology improves are only expected to drive this growth even further. REC CEO Steve O’Neil told CNBC that the installation rates of solar double every two years, a trend that informs residential solar economics for homeowners even though just two percent of the planet’s electricity comes from converting sunlight to energy. This means there is plenty of room for expansion. The world’s current solar capacity is 305 gigawatts, compared to just 50 gigawatts in 2010.

In addition, he pointed out that the price of solar energy has dropped by 70 percent since the year 2010 and continues to fall; it costs around eight cents per kilowatt hour at the moment. Another factor that could boost adoption is storage improvements, driven by affordable solar batteries that expand capacity, which will allow solar energy to be used even on overcast days.

Canada Electricity Decarbonization Costs indicate challenging greenhouse gas reductions across a fragmented grid, with wind, solar, nuclear, and natural gas tradeoffs, significant GDP impacts, and Net Zero targets constrained by intermittency and limited interties.

Key Points

Costs to cut power CO2 via wind, solar, gas, and nuclear, considering grid limits, intermittency, and GDP impacts.

✅ Alberta model: eliminate coal; add wind, solar, gas; 26-40% CO2 cuts

✅ Nuclear option enables >75% cuts at higher but feasible system costs

✅ National costs 1-2% GDP; reserves, transmission, land, and waste not included

Along with many western developed countries, Canada has pledged to reduce its greenhouse gas emissions by 40–45 percent by 2030 from 2005 emissions levels, and to achieve net-zero emissions by 2050.

This is a huge challenge that, when considered on a global scale, will do little to stop climate change because emissions by developing countries are rising faster than emissions are being reduced in developed countries. Even so, the potential for achieving emissions reduction targets is extremely challenging as there are questions as to how and whether targets can be met and at what cost. Because electricity can be produced from any source of energy, including wind, solar, geothermal, tidal, and any combustible material, climate change policies have focused especially on nations’ electricity grids, and in Canada cleaning up electricity is viewed as critical to meeting climate pledges.

Canada’s electricity grid consists of ten separate provincial grids that are weakly connected by transmission interties to adjacent grids and, in some cases, to electricity systems in the United States. At times, these interties are helpful in addressing small imbalances between electricity supply and demand so as to prevent brownouts or even blackouts, and are a source of export revenue for provinces that have abundant hydroelectricity, such as British Columbia, Manitoba, and Quebec.

Due to generally low intertie capacities between provinces, electricity trade is generally a very small proportion of total generation, though electricity has been a national climate success in recent years. Essentially, provincial grids are stand alone, generating electricity to meet domestic demand (known as load) from the lowest cost local resources.

Because climate change policies have focused on electricity (viz., wind and solar energy, electric vehicles), and Canada will need more electricity to hit net-zero according to the IEA, this study employs information from the Alberta electricity system to provide an estimate of the possible costs of reducing national CO2 emissions related to power generation. The Alberta system serves as an excellent case study for examining the potential for eliminating fossil-fuel generation because of its large coal fleet, favourable solar irradiance, exceptional wind regimes, and potential for utilizing BC’s reservoirs for storage.

Using a model of the Alberta electricity system, we find that it is infeasible to rely solely on renewable sources of energy for 100 percent of power generation—the costs are prohibitive. Under perfect conditions, however, CO2 emissions from the Alberta grid can be reduced by 26 to 40 percent by eliminating coal and replacing it with renewable energy such as wind and solar, and gas, but by more than 75 percent if nuclear power is permitted. The associated costs are estimated to be some $1.4 billion per year to reduce emissions by at most 40 percent, or $1.9 billion annually to reduce emissions by 75 percent or more using nuclear power (an option not considered feasible at this time).

Based on cost estimates from Alberta, and Ontario’s experience with subsidies to renewable energy, and warnings that the switch from fossil fuels to electricity could cost about $1.4 trillion, the costs of relying on changes to electricity generation (essentially eliminating coal and replacing it with renewable energy sources and gas) to reduce national CO2 emissions by about 7.4 percent range from some $16.8 to $33.7 billion annually. This constitutes some 1–2 percent of Canada’s GDP.

The national estimates provided here are conservative, however. They are based on removing coal-fired power from power grids throughout Canada. We could not account for scenarios where the scale of intermittency turned out worse than indicated in our dataset—available wind and solar energy might be lower than indicated by the available data. To take this into account, a reserve market is required, but the costs of operating such a capacity market were not included in the estimates provided in this study. Also ignored are the costs associated with the value of land in other alternative uses, the need for added transmission lines, environmental and human health costs, and the life-cycle costs of using intermittent renewable sources of energy, including costs related to the disposal of hazardous wastes from solar panels and wind turbines.

Germany Renewable Energy Milestone marks renewables supplying 53% of power, with record onshore wind and peak solar; hydrogen-ready gas plants and grid upgrades are planned to balance variability amid Germany's coal phase-out.

Key Points

It marks renewables supplying 53% of Germany's power, driven by wind and solar records in the energy transition.

✅ 53% of generation and 52% of consumption in 2024

✅ Onshore wind hit record; June solar peaked

✅ 24 GW hydrogen-ready gas plants planned for grid balancing

For the first time, renewable energy sources have surpassed half of Germany's electricity production this year, as indicated by data from sustainable energy organizations.

Preliminary figures from the Center for Solar Energy and Hydrogen Research alongside the German Association of Energy and Water Industries (BDEW) show that the contribution of green energy has risen to 53%, echoing how renewable power surpassed fossil fuels in Europe recently, a significant increase from 44% in the previous year.

The year saw a record output from onshore wind energy, as investments in European wind power climbed, and an unprecedented peak in solar energy production in June, as reported by the organizations. Additionally, renewable sources constituted 52% of Germany's total power consumption, marking an increase of approximately five percentage points.

Germany, Europe's leading economy, heavily impacted by Russia's reduced natural gas supplies last year, as Europeans push back from Russian oil and gas across the region, has been leaning on renewable sources to bridge the energy gap. This shift comes even as the country temporarily ramped up coal usage last winter. Having phased out its nuclear power plants earlier this year, Germany aims for an 80% clean energy production by 2030.

In absolute numbers, Germany produced a record level of renewable energy this year, supported by a solar power boost during the energy crisis, approximately 267 billion kilowatt-hours, according to the associations. A decrease of 11% in overall energy production facilitated a reduced reliance on fossil fuels.

However, Europe's transition to more sustainable energy sources, particularly offshore wind, has encountered hurdles such as increased financing and component costs, even as neighbors like Ireland pursue an ambitious green electricity goal within four years. Germany continues to face challenges in expanding its renewable energy capacity, as noted by BDEW’s executive board chairwoman, Kerstin Andreae.

Andreae emphasizes that while energy companies are eager to invest in the transition, they often encounter delays due to protracted approval processes, bureaucratic complexities, and scarcity of land despite legislative improvements.

German government officials are close to finalizing a strategy this week for constructing multiple new gas-fired power plants, despite findings that solar plus battery storage can be cheaper than conventional power in Germany, a plan estimated to cost around 40 billion euros ($44 billion). This initiative is a critical part of Germany's strategy to mitigate potential power shortages that might result from the discontinuation of coal power, particularly given the variability in renewable energy sources.

A crucial meeting involving representatives from the Economy and Finance Ministries, along with the Chancellor's Office, is expected to occur late Tuesday. The purpose is to finalize this agreement, according to sources who requested anonymity due to restrictions on public disclosure.

The Economy Ministry, spearheading this project, confirmed that intensive discussions are ongoing, although no further details were disclosed.

Germany's plan involves utilizing approximately 24 gigawatts (GW) of energy from hydrogen, including emerging offshore green hydrogen options, and gas-fired power plants to compensate for the fluctuations in wind and solar power generation. However, the proposal has faced challenges, particularly regarding the allocation of public funds for these projects, with disagreements arising with the European Union's executive in Brussels.

Environmental groups have also expressed criticism of the strategy. They advocate for an expedited end to fossil fuel usage and remain skeptical about the energy sector's arguments favoring natural gas as a transitional fuel. Despite natural gas emitting less carbon dioxide than coal, environmentalists question its role in Germany's energy future.

U.S. Clean Energy Transition accelerates with IRA and BIL, boosting renewable energy, solar PV, battery storage, EV adoption, manufacturing, grid resilience, and jobs while targeting carbon-free electricity by 2035 and net-zero emissions by 2050.

Key Points

U.S. shift to renewables under IRA and BIL scales solar, storage, and EVs toward carbon-free power by 2035.

✅ Renewables reached ~22% of U.S. electricity generation in 2022.

✅ Nearly $13b in PV manufacturing; 94 plants; 25k jobs announced.

✅ Battery storage grew from 3% in 2017 to 36% by H1 2023.

In recent years, the United States has made remarkable strides in embracing renewable energy, with notable solar and wind growth helping to position itself for a more sustainable future. This transition has been driven by a combination of factors, including environmental concerns, economic opportunities, and technological advancements.

With the introduction of the Inflation Reduction Act (IRA) and the Bipartisan Infrastructure Law (BIL), the United States is rapidly advancing its journey towards clean energy solutions.

To underscore the extent of this progress, consider the following vital statistics: In 2022, renewable energy sources (including hydroelectric power) accounted for approximately 22% of the nation's electricity generation, and renewables surpassed coal in the mix that year, while the share of renewables in total electricity generation capacity had risen to around 30% and the nation is moving toward 30% electricity from wind and solar as well.

Notably, in the transportation sector, consumers are increasingly embracing zero-emission fuels, such as electric vehicles. In 2022, battery electric vehicles (BEVs) represented 5.6% of new vehicle registrations, surging to 7.1% by the first half of 2023, according to estimates from EUPD Research.

The United States has set ambitious targets, including achieving 100% carbon pollution-free electricity by 2035 and aiming for economy-wide net-zero greenhouse gas emissions by no later than 2050, and policy proposals such as Biden's solar plan reinforce these goals for the power sector. These targets are poised to provide a significant boost to the clean energy sector in the country, reaffirming its commitment to a sustainable and environmentally responsible future.

IRA and BIL: Catalysts for Growth

The IRA and BIL represent a transformative shift in the landscape of clean energy policy, heralding a new era for the solar and energy storage sectors in the United States. The IRA allocates substantial resources to address the climate crisis, fortify domestic clean energy production, and solidify the U.S. as a global leader in clean energy manufacturing.

According to the U.S. Department of Energy (DOE), an impressive investment exceeding $120 billion has been announced for the U.S. battery manufacturing and supply chain sector since the introduction of IRA and BIL. Additionally, plans have been unveiled for over 200 new or expanded facilities dedicated to minerals, materials processing, and manufacturing. This move is expected to create more than 75,000 potential job opportunities, strengthening the nation's workforce.

Following the introduction of IRA and BIL, solar photovoltaic (PV) manufacturing in the U.S. has also witnessed a substantial surge in planned investments, totaling nearly $13 billion, as reported by the DOE. Furthermore, a total of 94 new and expanded PV manufacturing plants have been announced, potentially generating over 25,000 jobs in the country.

Booming Solar Sector

In recent years, the U.S. solar sector has outpaced other energy sources, including a surging wind sector and natural gas, in terms of capacity growth. EUPD Research estimates reveal a notable upward trend in the contribution of solar capacity to annual power capacity additions, as 82% of the 2023 pipeline consists of wind, solar, and batteries across utility-scale projects. This trajectory has risen from 37% in 2019 to 38% in 2020, further increasing to 44% in 2021 and an impressive 45% in 2022.

Although the country experienced a temporary setback in 2022 due to pandemic-related delays, trade law enforcement, supply chain disruptions, and rising costs, it is now on track to make a historic addition to its PV capacity in 2023. According to EUPD Research's 2023 forecast, the U.S. is poised to achieve its largest-ever expansion in PV capacity, estimated at 32 to 35 GWdc, assuming the installation of all planned utility-scale capacity, and solar generation rose 25% in 2022 as a supportive indicator. Additionally, from 2023 to 2028, the U.S. is projected to add approximately 233 GWdc of PV capacity.

In terms of cumulative installed PV capacity (including utility-scale, commercial and industrial, and residential) on a state-by-state basis, California holds the top position, followed by Texas, Florida, North Carolina, and Arizona. Remarkably, Texas is rapidly expanding its utility-scale PV capacity and may potentially surpass California in the next two years.

Rapid Growth in Battery Storage

Battery energy storage has emerged as the dominant and rapidly expanding source of energy storage in the U.S. in recent years. The proportion of battery storage in the country's energy storage capacity has surged dramatically, increasing from a mere 3% in 2017 to a substantial 36% in the first half of 2023.

nanoFlowcell Bi-ION Flow Battery delivers renewable-energy storage for EVs and grids, using seawater-derived electrolyte, membrane stacks, fast refueling, low-cost materials, scalable tanks, and four-motor performance with long range and lightweight energy density.

Key Points

A flow cell using Bi-ION to power EVs and grids with fast refueling and scalable, low-cost storage.

✅ Seawater-derived Bi-ION electrolyte; safe, nonflammable, low cost

✅ Fast refueling via dual tanks; membrane stack generates power

✅ EV range up to 1200 miles; scalable for grid-scale storage

nanoFlowcell is a European company headquartered in London that focuses on flow battery technology. Flow batteries are an intriguing concept. Unlike lithium batteries or fuel cells, they store electricity in two liquid chambers separated by a membrane. They hold enormous potential for low cost, environmentally friendly energy storage because the basic materials are cheap and abundant. To add capacity, simply make the tanks larger.

While that makes flow batteries ideal for energy storage — whether in the basement of a building or as part of a grid scale installation that utilities weigh against options like hydrogen for power companies today in practice — their size and weight make them a challenge for use in vehicles. That hasn’t stopped nanoFlowcell from designing a number of concept and prototype vehicles over the past 10 years and introducing them to the public at the Geneva auto show. Its latest concept is a tasty little crumpet known as the Quantino 25.

The Flow Battery & Bi-ION Fluid
The thing that makes the nanoFlowcell ecosystem work is an electrically charged fluid called Bi- ION derived from seawater or reclaimed waste water. It works sort of like hydrogen in a fuel cell, a frequent rival in debates over the future of vehicles today for many buyers. Pump hydrogen in, run it through a fuel cell, and get electricity out. With the Quantino 25, which the company calls a “2+2 sports car,” you pump two liquids to the membrane interface to make electricity.

There are two 33-gallon tanks mounted low in the chassis much the way a lithium-ion battery pack fits into a normal electric car. Fill up with Bi-ION, and you have a car that will dash to 100 km/h in 2.5 seconds, thanks to its 4 electric motors with 80 horsepower each. And get this. According to Autoblog, the company says with full tanks, the Quantino 25 has a range of 1200 miles! Goodbye range anxiety, hello happy motoring.

We should point out that water weighs about 8 pounds per gallon, so the “fuel” to travel 1200 miles would weigh roughly 528 pounds. A conventional lithium-ion battery pack with its attendant cooling apparatus that could travel that far would weigh at least 3 times as much, even as EV battery recycling advances aim for a circular economy today. Granted, the Quantino 25 is not a production car and very few people have ever driven one, but that kind of range vs weight ratio has got to get your whiskers twitching a little in anticipation.

Actually, the folks at Autocar did drive an early prototype in 2016 at the TCS test track near Zurich, Switzerland, and determined that it was a real driveable car. My colleague Jennifer Sensiba reported in April of 2019 that the company’s Quantino test vehicle passed the 350,000 km mark (220,000 miles) with no signs of damage to the membrane or the pumps, and didn’t seem to have suffered any wear at all. The vehicle’s engineers pointed out that it had driven for 10,000 hours at this point. The company says it wants to offer its flow battery technology to EV manufacturers and give the system a 50,000-hour guarantee. That translates to well over 1 million miles of driving.

The problem, of course, is that there is no Bi-ION refueling infrastructure just yet, but that doesn’t mean someday there couldn’t be. Tesla had no Supercharger network when it first started either and things turned out reasonably well for Musk and company.

nanoFlowcell USA Announced
nanoFlowcell announced this week that it has established a new division based in New York to bring its flow battery technology to America. The mission of the new division is to adapt the nanoFlowcell process to US-specific applications and develop nanoFlowcell applications in America. Priority one is beginning series production of flow battery vehicles as well as the constructing a large scale bi-ION production facility that will provide transportable renewable energy and could complement vehicle-to-grid power models for communities for nanoFlowcell applications.

The Bi-ION electrolyte is a high density energy carrier that makes renewable energies storable and transportable in large quantities. The company says it will produce the energy carrier bi-ION from 100 percent renewable energy. Flow cell energy technology is an important solution to substantially reduce global greenhouse gas emissions as laid out in the Paris Agreement, the company says. Its many benefits include being a safe and clean energy source for many energy intensive processes and transportation services.

“Our nanoFlowcell flow cell and bi-ION energy carrier are key technologies for a successful energy transition,” says Nunzio La Vecchia, CEO of nanoFlowcell Holdings. “We need to make energy from renewable energy safe, storable and transportable to drive environmentally sustainable economic growth. This requires a well thought out strategy and the development of the appropriate infrastructure. With the establishment of nanoFlowcell USA, we are reaching an important milestone in this regard for our future corporate development.”

Focus On Renewable Energy
The production costs of Bi-ION are directly linked to the cost of electricity from renewable sources. With the accelerated expansion of renewable energy under the Inflation Reduction Act along with EV grid flexibility efforts across markets, nanoFlowcell expects the cost of electricity from solar power to be relatively low in the future which will further strengthen the competitiveness of energy sources such as Bi-ION.

“With the Inflation Reduction Act, the U.S. has made the largest investment in clean energy in U.S. history, and the potential implications for renewable energy are far-reaching.” But La Vecchia points out, “We will not seek government investments for nanoFlowcell USA to expand our manufacturing facilities and infrastructure in the United States. Where appropriate, we will enter into strategic partnerships to build and expand manufacturing and infrastructure, and to integrate nanoFlowcell technologies into all sectors of the economy.”

“More importantly, with nanoFlowcell USA, we want to help accelerate the decarbonization of the global economy and create economic, social and ecological prosperity. After all, estimates suggest that the clean energy sector will create 500,000 additional jobs. We want to do our part to make this happen.”

‍The Takeaway
nanoFlowcell is about more than electric cars. It wants to get involved in grid-scale energy storage, and moves like Mercedes-Benz energy storage venture signal momentum in the sector today. But to those of us soaking in the hot tub warmed by excess heat from a nearby data center here at CleanTechnica global headquarters, it seems that its contribution to emissions-free transportation could be enormous. Maybe some of those companies still chasing the hydrogen fuel cell dream, as a recent hydrogen fuel cell report notes Europe trailing Asia today, might find the company’s flow battery technology cheaper and more durable without all the headaches that go with making, storing, and transporting hydrogen.

A Bi-ION refueling station would probably cost less than a tenth as much as a hydrogen filling station. A link-up with a major manufacturer would make it easier to build out the infrastructure needed to make this dream a reality. Hey, people laughed at Tesla in 2010. If nothing else, this is a company we will be keeping our eye on.

DOE LNG Export Approvals expand flexibility for Cheniere's Sabine Pass and Corpus Christi to ship to non-FTA countries, boosting U.S. supply to Europe while advancing methane emissions reductions and strengthening global energy security.

Key Points

DOE LNG export approvals authorize Sabine Pass and Corpus Christi to sell full-capacity LNG to non-FTA markets.

✅ Exports allowed to any non-FTA country, including Europe

✅ Capacity covers Sabine Pass and Corpus Christi terminals

✅ DOE targets methane reductions across oil and gas

The U.S. Department of Energy (DOE) today issued two long-term orders authorizing liquefied natural gas (LNG) exports from two current operating LNG export projects, Cheniere Energy Inc.’s Sabine Pass in Louisiana and Corpus Christi in Texas, following a recent deep freeze that slammed the American energy sector.

The two orders allow Sabine Pass and Corpus Christi additional flexibility to export the equivalent of 0.72 billion cubic feet per day of natural gas as LNG to any country with which the U.S. does not have a free trade agreement, including all of Europe, such as the UK natural gas market as well.

While U.S. exporters are already exporting at or near their maximum capacity, with today's issuances, every operating U.S. LNG export project has approval from DOE to export its full capacity to any country where not prohibited by U.S. law or policy constraints in place.

The U.S. is now the top global exporter of LNG and exports are set to grow an additional 20% beyond current levels by the end of this year as additional capacity comes online, even as a domestic energy crisis influences electricity and gas markets.  In January 2022, U.S. LNG supplied more than half of the LNG imports into Europe for the month.

With the expected rise in LNG exports, DOE is particularly focused on driving down methane emissions in the oil and gas sector both domestically and abroad, leveraging the deep technical expertise of the Department, and supporting nuclear innovation as well.

U.S. LNG remains an important component to global energy security worldwide and DOE remains committed to finding ways to help our allies and trading partners, including support to Ukraine and others with the energy supplies they need while continuing to work to mitigate the impact of climate change.
