Can food waste be turned into green hydrogen to produce electricity?

EV Charging Infrastructure accelerates with federal funding, NEVI corridors, and Level 2/3 DC fast charging to cut range anxiety, support apartment dwellers, and scale to 500,000 public chargers alongside tax credits and state mandates.

Key Points

The network of public and private hardware, software, and policies enabling reliable Level 2/3 EV charging at scale.

✅ $7,500/$4,000 tax credits spur adoption and charger demand

✅ NEVI funding builds 500,000 public, reliable DC fast chargers

✅ Equity focus: apartment, curbside, bidirectional and inductive tech

Speaking in front of a line of the latest electric vehicles (EVs) at this month’s North American International Auto Show, President Joe Biden declared: “The great American road trip is going to be fully electrified.”

Most vehicles on the road are still gas guzzlers, but Washington is betting big on change, with EV charging networks competing to expand as it hopes that major federal investment will help reach a target set by the White House for 50% of new cars to be electric by 2030. But there are roadblocks – specifically when it comes to charging them all. “Range anxiety,” or how far one can travel before needing to charge, is still cited as a major deterrent for potential EV buyers.

The auto industry recently passed the 5% mark of EV market share – a watershed moment, arriving ahead of schedule according to analysts, before rapid growth. New policies at the state and local level could very well spur that growth: the Inflation Reduction Act, which passed this summer, offers tax credits of $4,000 to purchase a used EV and up to $7,500 for certain new ones. In August, California, the nation’s largest state and economy, announced rules that would ban all new gas-powered cars by 2035, as part of broader grid stability efforts in the state. New York plans to follow.

So now, the race is on to provide chargers to power all those new EVs.

The administration’s target of 500,000 public charging units by 2030 is a far cry from the current count of nearly 50,000, according to the Department of Energy’s estimate. And those new chargers will have to be fast – what’s known as Level 2 or 3 charging – and functional in order to create a truly reliable system, even as state power grids face added demands across regions. Today, many are not.

Last week, the White House approved plans for all 50 states, along with Washington DC, and Puerto Rico, to set up chargers along highways, unlocking $1.5bn in federal funding to that end, as US automakers’ charger buildout to complement public funds. The money comes from the landmark infrastructure bill passed last year, which invests $7.5bn for EV charging in total.

But how much of that money is spent is largely going to be determined at the local level, amid control over charging debates among stakeholders. “It’s a difference between policy and practice,” said Drew Lipsher, the chief development officer at Volta, an EV charging provider. “Now that the federal government has these policies, the question becomes, OK, how does this actually get implemented?” The practice, he said, is up to states and municipalities.

As EV demand spikes, a growing number of cities are adopting policies for EV charging construction. In July, the city of Columbus passed an “EV readiness” ordinance, which will require new parking structures to host charging stations proportionate to the number of total parking spots, with at least one that is ADA-accessible. Honolulu and Atlanta have passed similar measures.

One major challenge is creating a distribution model that can meet a diversity of needs.

At the moment, most EV owners charge their cars at home with a built-in unit, which governments can help subsidize. But for apartment dwellers or those living in multi-family homes, that’s less feasible. “When we’re thinking about the largest pieces of the population, that’s where we need to really be focusing our attention. This is a major equity issue,” said Alexia Melendez Martineau, the policy manager at Plug-In America, an EV consumer advocacy group.

Bringing power to people is one such solution. In Hoboken, New Jersey, Volta is working with the city to create a streetside charging network. “The network will be within a five-minute walk of every resident,” said Lipsher. “Hopefully this is a way for us to really import it to cities who believe public EV charging infrastructure on the street is important.” Similarly, in parts of Los Angeles – as in Berlin and London – drivers can get a charge from a street lamp.

And there may be new technologies that could help, exciting experts and EV enthusiasts alike. That could include the roads themselves charging EVs through a magnetizable concrete technology being piloted in Indiana and Detroit. And bidirectional charging, where, similar to solar panels, drivers can put their electricity back into the grid – or perhaps even to another EV, through what’s known as electric vehicle supply equipment (EVSE). Nissan approved the technology for their Leaf model this month.

Poland Solar PV Boom drives record installations, rooftop and utility-scale growth, EU-aligned incentives, net metering, PPAs, and auctions, pushing capacity toward 8.3 GW by 2024 while prosumers, grid upgrades, and energy management expand.

Key Points

A rapid expansion of Poland's PV market, driven by incentives, PPAs, and prosumers across rooftop and utility-scale.

✅ 2.2 GW added in 2020, triple 2019, led by small-scale prosumers

✅ Incentives: My Current, Clean Air, Agroenergia, net metering

✅ Growth toward 8.3 GW by 2024; PPAs and auctions scale utility

Photovoltaics (PV) is booming in Poland. According to SolarPower Europe, 2.2 gigawatts (GW) of solar power was installed in the country in 2020 - nearly three times as much as the 823 megawatts (MW) installed in 2019. This places Poland fourth across Europe, behind Germany, where a solar power boost has been underway (4.8 GW added in 2020), the Netherlands (2.8 GW) and Spain (2.6 GW). So all eyes in the industry are on the up-and-coming Polish market. The solar industry will come together at Intersolar Europe Restart 2021, taking place from October 6 to 8 at Messe München. As part of The smarter E Europe Restart 2021, manufacturers, suppliers, distributors and service providers will all present their products and innovations at the world's leading exhibition for the solar industry.

All signs point to continued strong growth, with renewables on course to set records across markets. An intermediate, more conservative EU Market Outlook forecast from SolarPower Europe expects the Polish solar market to grow by 35 percent annually, meaning that it will have achieved a PV capacity of 8.3 GW by 2024 as solar reshapes Northern Europe's power prices over the medium term. "PV in Poland is booming at every level - from private and commercial PV rooftop systems to large free-standing installations," says Dr. Stanislaw Pietruszko, President of the Polish Society for Photovoltaics (PV Poland). According to the PV Poland, the number of registered small-scale systems - those under 50 kilowatts (kW) - with an average capacity of 6.5 kilowatts (kW) grew from 155,000 (992 MW) at the end of 2019 to 457,400 (3 GW) by the end of 2020. These small-scale systems account for 75 percent of all PV capacity installed in Poland. Larger PV projects with a capacity of 4 GW have already been approved for grid connection, further attesting to the forecast growth.

8,000 people employed in the PV industry
Andrzej Kazmierski, Deputy Director of the Department for Low-emission Economy within the Polish Ministry of Economic Development, Labour and Technology, explained in the Intersolar Europe webinar "A Rising Star: PV Market Poland" at the end of March 2021 that the PV market volume in Poland currently amounts to 2.2 billion euros, with 8,000 people employed in the industry. According to Kazmierski, the implementation of the Renewable Energy Directive (RED II) in the EU, intended to promote energy communities and collective prosumers as well as long-term power purchase agreements (PPAs), will be a critical challenge, and ongoing Berlin PV barriers debates highlight the importance of regulatory coordination. Renewable energy must be integrated with greater focus into the energy system, and energy management and the grids themselves must be significantly expanded as researchers work to improve solar and wind integration. The government seeks to create a framework for stable market growth as well as to strengthen local value creation.

Government incentive programs in Poland
In addition to drastically reduced PV costs, reinforced by China's rapid PV expansion, and growing environmental consciousness, the Polish PV market is being advanced by an array of government-funded incentive programs such as My Current (230 million euros) and Clean Air as well as thermo-modernization. The incentive program Agroenergia (50 million euros) is specifically geared toward farmers and offers low-interest loans or direct subsidies for the construction of solar installations with capacities between 50 kW and 1 MW. Incentive programs for net metering have been extended to small and medium enterprises to provide stronger support for prosumers. Solar installations producing less than 50 kW benefit from a lower value-added tax of just eight percent (compared to the typical 23 percent). The acquisition and installation costs can be offset against income, in turn reducing income tax.
Government-funded auctions are also used to finance large-scale facilities, where the government selects operators of systems running on renewable energy who offer the lowest electricity price and funds the construction of their facilities. The winner of an auction back in December was an investment project for the construction of a 200 MW solar park in the Pomeranian Voivodeship.

Companies turn to solar power for self-consumption
Furthermore, Poland is now playing host to larger solar projects that do not rely on subsidies, as Europe's demand lifts US equipment makers amid supply shifts, such as a 64 MW solar farm in Witnica being built on the border to Germany whose electricity will be sold to a cement factory via a multi-year power purchase agreement. A new factory in Konin (Wielkopolska Voivodeship) for battery cathode materials to be used in electric cars will be powered with 100-percent renewable electricity. Plus, large companies are increasingly turning to solar power for self-consumption. For example, a leading manufacturer of metal furniture in Suwalki (Podlaskie Voivodeship) in northeastern Poland has recently started meeting its demand using a 2 MW roof-mounted and free-standing installation on the company premises.

Electric Vehicles Lower Electricity Rates by boosting demand, enabling fixed-cost recovery, and encouraging off-peak charging that balances the grid, reduces peaker plant use, and funds utility upgrades, with V2G poised to expand system benefits.

Key Points

By boosting off-peak demand and utility revenue, EVs spread fixed costs, cut peaker use, and stabilize the grid.

✅ Off-peak charging flattens load, reducing peaker plant reliance

✅ Higher kWh sales spread fixed grid costs across more users

✅ V2G can supply power during peaks and emergencies

Electric vehicles (EVs) are gaining popularity, and it appears they might be offering an unexpected benefit to everyone – including those who don't own an EV.  A new study by the non-profit research group Synapse Energy Economics suggests that the growth of electric cars is actually contributing to lower electricity rates for all ratepayers.

How EVs Contribute to Lower Rates

The study explains several factors driving this surprising trend:

• Increased Electricity Demand: Electric vehicles require additional electricity, boosting rising electricity demand on the grid.
• Optimal Charging Times: Many EV owners take advantage of off-peak charging discounts. Charging cars overnight, when electricity demand is typically low, helps to balance state power grids and reduce the need for expensive "peaker" power plants, which are only used to meet occasional spikes in demand.
• Revenue for Utilities: Electric car charging can generate substantial revenue for utilities, potentially supporting investment in grid improvements, energy storage solutions and renewable energy projects that can bring long-term benefits to all customers.

A Significant Impact

The Synapse Energy Economics study analyzed data from 2011 to 2021 and concluded that EV drivers already contributed over $3 billion more to the grid than their associated costs. That, in turn, reduced monthly electricity bills for all customers.

Benefits May Grow

While the impact on electricity rates has been modest so far, experts anticipate the benefits to grow as EV adoption rates increase. Vehicle-to-grid (V2G) technology, which allows EVs to feed stored power back into the grid during emergencies or high-demand periods, has the potential to further optimize electricity usage patterns and create additional benefits for electric utilities and customers.

National Implications

The findings of this study offer hope to other regions seeking to increase electric vehicle adoption rates and support California's grid stability efforts, which is a key step towards reducing transportation-related greenhouse gas emissions. This news may alleviate concerns about potential electricity rate hikes driven by EV adoption and suggests that the benefits will be broadly shared.

More than Just Environmental Benefits

Electric vehicles bring a clear environmental advantage by reducing reliance on fossil fuels. However, this unexpected economic benefit could further strengthen the case for accelerating the adoption of electric vehicles. This news might encourage policymakers and the public to consider additional incentives or policies, including vehicle-to-building charging approaches, to promote the transition to this cleaner mode of transportation knowing it can yield benefits beyond environmental goals.

Vehicle-to-Home (V2H) Power enables EVs to act as backup generators and home batteries, using bidirectional charging, inverters, and rooftop solar to cut energy costs, stabilize the grid, and provide resilient, outage-proof electricity.

Key Points

Vehicle-to-Home (V2H) Power lets EV batteries run household circuits via bidirectional charging and an inverter.

✅ Cuts energy bills using solar, time-of-use rates, and storage

✅ Provides resilient backup during outages, storms, and blackouts

✅ Enables grid services via V2G/V2H with smart chargers

When the power went out at Nate Graham’s New Mexico home last year, his family huddled around a fireplace in the cold and dark. Even the gas furnace was out, with no electricity for the fan. After failing to coax enough heat from the wood-burning fireplace, Graham’s wife and two children decamped for the comfort of a relative’s house until electricity returned two days later.

The next time the power failed, Graham was prepared. He had a power strip and a $150 inverter, a device that converts direct current from batteries into the alternating current needed to run appliances, hooked up to his new Chevy Bolt, an electric vehicle. The Bolt’s battery powered his refrigerator, lights and other crucial devices with ease. As the rest of his neighborhood outside Albuquerque languished in darkness, Graham’s family life continued virtually unchanged. “It was a complete game changer making power outages a nonissue,” says Graham, 35, a manager at a software company. “It lasted a day-and-a-half, but it could have gone much longer.”

Today, Graham primarily powers his home appliances with rooftop solar panels and, when the power goes out, his Chevy Bolt. He has cut his monthly energy bill from about $220 to $8 per month. “I’m not a rich person, but it was relatively easy,” says Graham “You wind up in a magical position with no [natural] gas, no oil and no gasoline bill.”

Graham is a preview of what some automakers are now promising anyone with an EV: An enormous home battery on wheels that can reverse the flow of electricity to power the entire home through the main electric panel.

Beyond serving as an emissions-free backup generator, the EV has the potential of revolutionizing the car’s role in American society, with California grid programs piloting vehicle-to-grid uses, transforming it from an enabler of a carbon-intensive existence into a key step in the nation’s transition into renewable energy.

Home solar panels had already been chipping away at the United States’ centralized power system, forcing utilities to make electricity transfer a two-way street. More recently, home batteries have allowed households with solar arrays to become energy traders, recharging when electricity prices are low, replacing grid power when prices are high, and then sell electricity back to the grid for a profit during peak hours.

But batteries are expensive. Using EVs makes this kind of home setup cheaper and a real possibility for more Americans as the American EV boom accelerates nationwide.

So there may be a time, perhaps soon, when your car not only gets you from point A to point B, but also serves as the hub of your personal power plant.

I looked into new vehicles and hardware to answer the most common questions about how to power your home (and the grid) with your car.

Why power your home with an EV battery

America’s grid is not in good shape. Prices are up and reliability is down, and many state power grids face new challenges from rising EV adoption. Since 2000, the number of major outages has risen from less than two dozen to more than 180 per year, based on federal data, the Wall Street Journal reports. The average utility customer in 2020 endured about eight hours of power interruptions, double the previous decade.

Utilities’ relationship with their customers is set to get even rockier. Residential electricity prices, which have risen 21 percent since 2008, are predicted to keep climbing as utilities spend more than $1 trillion upgrading infrastructure, erecting transmission lines for renewable energy and protecting against extreme weather, even though grids can handle EV loads with proper management and planning.

U.S. homeowners, increasingly, are opting out. About 8 percent of them have installed solar panels. An increasing number are adding home batteries from companies such as LG, Tesla and Panasonic. These are essentially banks of battery cells, similar to those in your laptop, capable of storing energy and discharging electricity.

EnergySage, a renewable energy marketplace, says two-thirds of its customers now request battery quotes when soliciting bids for home solar panels, and about 15 percent install them. This setup allows homeowners to declare (at least partial) independence from the grid by storing and consuming solar power overnight, as well as supplying electricity during outages.

But it doesn’t come cheap. The average home consumes about 20 kilowatt-hours per day, a measure of energy over time. That works out to about $15,000 for enough batteries on your wall to ensure a full day of backup power (although the net cost is lower after incentives and other potential savings).

How an EV battery can power your home

Ford changed how customers saw their trucks when it rolled out a hybrid version of the F-150, says Ryan O’Gorman of Ford’s energy services program. The truck doubles as a generator sporting as many as 11 outlets spread around the vehicle, including a 240-volt outlet typically used for appliances like clothes dryers. During disasters like the 2021 ice storm that left millions of Texans without electricity, Ford dealers lent out their hybrid F-150s as home generators, showing how mobile energy storage can bring new flexibility during outages.

The Lightning, the fully electric version of the F-150, takes the next step by offering home backup power. Under each Lightning sits a massive 98 kWh to 131 kWh battery pack. That’s enough energy, Ford estimates, to power a home for three days (10 days if rationing). “The vehicle has an immense amount of power to move that much metal down the road at 80 mph,” says O’Gorman.

US Renewable Energy Growth drives the US electricity mix as wind, solar, and hydropower rise while coal, natural gas, and nuclear decline, boosting market share month over month and year over year across the grid.

Key Points

US Renewable Energy Growth tracks rising wind, solar, and hydro shares in the mix as coal, gas, and nuclear decline.

✅ Wind and solar surpass nuclear in April share

✅ Renewables reach 29.3% of US electricity in April

✅ Coal and natural gas shares trend lower since 2020

Electricity generated by renewable energy sources continues to grow month over month and year over year in the United States. In April 2022, the share of US electricity coming from renewable energy was up to 29.3%, surpassing a record April level reported previously in national data. That was up from 24.8% in April 2020 and 25.7% in April 2021.

Looking at the first four months of the year, renewables provided 25.5% of US electricity, and were the second-most U.S. source in 2020 as well, while the figure for January–April 2020 was 21.7% and the figure for January–April 2021 was 22.5%.

Coal power (20.2% of US electricity) was down year over year in this time period (from 22% in January–April 2021), even as renewables surpassed coal in 2022 nationwide, but is admittedly still a bit higher than it was in January–April 2020 (16.8%).

Electricity from natural gas is also down year over year, but only very slightly (34.7% for both years). Though, it has dropped significantly since January–April 2020 (39.6%).

Electricity from nuclear power continued to take a steady, step-by-step tumble.

Wind & Solar Power Growth Strong
As reported earlier, April was the first month that wind and solar power provided more electricity than nuclear across the United States. Wind and solar power provided 21% of US electricity, while nuclear power provided 17.8% of US electricity (coal, incidentally, also provided 17.8% of US electricity, but wind and solar had provided more electricity than coal in some previous months as well).

Wind and solar power’s combined market share for the first four months of the year was up from just 14.6% in 2020 and 18.4% in 2021.

Looking at their growth year over year, you can see strong and continuous expansion of solar-provided electricity and wind-provided electricity, amid favorable government plans that have supported deployment.

Solar grew from 2.9% in January–April 2020 to 3.6%in January–April 2021 to, eventually, 4.4% in January–April 2022, with solar's 2022 share rising to 4.7% for the full year. Wind rose from 9.2% to 10.3% to 12.2%.

Together, wind and solar were up from 12.1% in January–April 2020 to 13.9% in January–April 2021, reflecting a surge in wind power within the U.S. electricity mix over this period, to 16.7% January–April 2022.

Hydropower (6.5%) is holding approximately the same position as the same period in 2021 (6.5%), but it is down a significant chunk from April 2020 (8.2%).

Pyroelectric Energy Harvesting captures low-grade heat via thin-film materials, converting temperature fluctuations into power for waste heat recovery in electronics, vehicles, and industrial machinery, offering a thermoelectric alternative for microelectronics and exascale systems.

Key Points

Thin-film pyroelectric harvesting turns temperature changes into electricity, enabling low-grade waste heat recovery.

✅ Converts low-grade heat fluctuations into usable power

✅ Thin-film design suits microelectronics and edge devices

✅ Alternative to thermoelectrics for waste heat recovery

The electronic device you are reading this on is currently producing a modest to significant amount of waste heat that emerging thermoelectric materials could help recover in principle. In fact, nearly 70% of the energy produced annually in the US is ultimately wasted as heat, much of it less than 100 degrees Celsius. The main culprits are computers and other electronic devices, vehicles, as well as industrial machinery. Heat waste is also a big problem for supercomputers, because as more circuitry is condensed into smaller and smaller areas, the hotter those microcircuits get.

It’s also been estimated that a single next-generation exascale supercomputer could feasibly use up to 10% of the energy output of just one coal-fired power station, and that nearly all of that energy would ultimately be wasted as heat.

What if it were possible to convert that heat energy into a useable energy source, and even to generate electricity at night from temperature differences as well?

#google#

It’s not a new idea, of course. In fact the possibility of thermoelectric energy generation, where thermal energy is turned into electricity was recognised as early as 1821, around the same time that Michael Faraday developed the electric motor.

Unfortunately, when the heat source is ‘low grade’, aka less than 100 degrees Celsius, a number of limitations arise, and related approaches for nighttime renewable generation face similar challenges as well. For it to work well, you need materials that have quite high electrical conductivity, but low thermal conductivity. It’s not an easy combination to come by.

Taking a different approach, researchers at the University of California, Berkeley, have developed thin-film that uses pyroelectric harvesting to capture heat-waste and convert heat to electricity in prototype demonstrations. The findings were published today in Nature Materials.
