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.

Europe must catch up with Asian countries on hydrogen fuel cells - report

Germany Hydrogen Fuel Cell Market gains momentum as policy, mobility, and R&D align; National Hydrogen Strategy, regulatory frameworks, and cost-of-ownership advances boost heavy transport, while Europe races Asia amid battery-electric competition and infrastructure scale-up.

 

Key Points

It is Germany and Europe's hydrogen fuel cell ecosystem across policy, costs, R&D, and mobility and freight deployments.

✅ Policy support via National Hydrogen Strategy and tax incentives

✅ TCO parity improves for heavy transport vs other low-emission tech

✅ R&D targets higher temps, compactness for road, rail, sea, air

 

In a new report examining the status of the German and European hydrogen fuel cell markets, the German government-backed National Platform Future of Mobility (NPM) says there is “a good chance that fuel cell technology can achieve a break-through in mobile applications,” even as the age of electric cars accelerates across markets.

However, Europe must catch up with Asian countries, it adds, even as a push for electricity shapes climate policy. For Germany and Europe to take on a leading role in fuel cell technologies, their industries need to be strengthened and sustainably developed, the report finds. In its paper, the NPM Working Group 4 – which aims to secure Germany as a place for mobility, battery cell production, recycling, training and qualification – states that the “chances of fuel cell technology achieving a break-through in the automotive industry – even in Europe – are better than ever,” echoing recent remarks from BMW's chief about hydrogen's appeal.

The development, expansion and use of the technology in various applications are now supported by “a significantly modified regulatory framework and new political ambitions, as stipulated in the National Hydrogen Strategy,” while updated forecasts show e-mobility driving electricity demand in Germany, the report stresses. In terms of cost of ownership, “hydrogen solutions can hold their own compared to other technologies” and there are “many promising developments in the transport sector, especially in heavy transport.”

If research and development efforts can help optimise installation space and weight as well as increase the operating temperature of fuel cells, hydrogen solutions can also become attractive for maritime, rail and air transport, even as other electrochemical approaches, such as flow battery cars, progress, the report notes. Tax incentives -- such as the Renewable Energy Sources Act (EEG) surcharge exemption for green hydrogen -- can contribute to the technology’s appeal, it adds.

Fuel cell drives are often seen as a way to decarbonise certain areas of transport, such as heavy trucks. However, producing the hydrogen in a sustainable way consumes a lot of renewable electricity that power companies must supply in other sectors, and experts say electricity vs hydrogen trade-offs favor battery-electric trucks because they are much cheaper to run than other low-emission technologies, including fuel cells.

The government's 2035 electric vehicle mandate is delusional

Canada 2035 Zero-Emission Vehicle Mandate sets EV sales targets, raising concerns over affordability, battery materials like lithium and copper, charging infrastructure, grid capacity, renewable energy mix, and policy impacts across provinces.

 

Key Points

Mandate makes all new light-duty vehicles zero-emission by 2035, affecting costs, charging, and electric grid planning.

✅ 100% ZEV sales target for cars, SUVs, light trucks by 2035

✅ Cost pressures from lithium, copper, nickel; EVs remain pricey

✅ Grid, charging build-out needed; impacts vary by provincial mix

 

Whether or not you want one, can afford one or think they will do essentially nothing to stop global warming, electric vehicles are coming to Canada en masse. This week, the Canadian government set 2035 as the “mandatory target” for the sale of zero-emission SUVs and light-duty trucks as part of ambitious EV goals announced by Ottawa.

That means the sale of gasoline and diesel cars has to stop by then. Transport Minister Omar Alghabra called the target “a must.” The previous target was 2040.

It is a highly aspirational plan that verges on the delusional according to skeptics of an EV revolution who argue its scale is overstated, even if it earns Canada – a perennial laggard on the emission-reduction front – a few points at climate conferences. Herewith, a few reasons why the plan may be unworkable, unfair or less green than advertised.

Liberals say by 2035 all new cars, light-duty trucks sold in Canada will be electric, as Ottawa develops EV sales regulations to implement the mandate.

Parkland to roll out electric-vehicle charging network in B.C. and Alberta

Sticker shock: There is a reason why EVs remain niche products in almost every market in the world (the notable exception is in wealthy Norway): They are bloody expensive and often in short supply in many markets. Unless EV prices drop dramatically in the next decade, Ottawa’s announcement will price the poor out of the car market. Transportation costs are a big issue with the unrich. The 2018 gilets jaunes mass protests in France were triggered by rising fuel costs.

While some EVs are getting cheaper, even the least expensive ones are about double the price of a comparable product with an internal combustion engine. Most EVs are luxury items. The market leader in Canada and the United States is Tesla. In Canada the cheapest Tesla, the Model 3 (“standard range plus” version), costs $49,000 before adding options and subtracting any government purchase incentives. A high-end Model S can set you back $170,000.

To be sure, prices will come down as production volumes increase. But the price decline might be slow for the simple reason that the cost of all the materials needed to make an EV – copper, cobalt, lithium, nickel among them – is climbing sharply and may keep climbing as production increases, straining supply lines.

Lithium prices have doubled since November. Copper has almost doubled in the past year. An EV contains five times more copper than a regular car. Glencore, one of the biggest mining companies, estimated that copper production needs to increase by a million tonnes a year until 2050 to meet the rising demand for EVs and wind turbines, a daunting task given the dearth of new mining projects.

Will EVs be as cheap as gas cars in a decade or so? Impossible to say, but given the recent price trends for raw materials, probably not.

Not so green: There is no such thing as a zero-emission vehicle, even if that’s the label used by governments to describe battery-powered cars. So think twice if you are buying an EV purely to paint yourself green, as research finds they are not a silver bullet for climate change.

In regions in Canada and elsewhere in the world that produce a lot of electricity from fossil-fuel plants, driving an EV merely shifts the output of greenhouse gases and pollutants from the vehicle itself to the generating plant (according to recent estimates, about 18% of Canada’s electricity comes from coal, natural gas and oil; in the United States, 60 per cent).

An EV might make sense in Quebec, where almost all the electricity comes from renewable sources and policymakers push EV dominance across the market. An EV makes little sense in Saskatchewan, where only 17 per cent comes from renewables – the rest from fossil fuels. In Alberta, only 8 per cent comes from renewables.

The EV supply chain is also energy-intensive. And speaking of the environment, recycling or disposing of millions of toxic car batteries is bound to be a grubby process.

Where’s the juice?: Since the roofs of most homes in Canada and other parts of the world are not covered in solar panels, plugging in an EV to recharge the battery means plugging into the electrical grid. What if millions of cars get plugged in at once on a hot day, when everyone is running air conditioners?

The next few decades could emerge as an epic energy battle between power-hungry air conditioners, whose demand is rising as summer temperatures rise, and EVs. The strain of millions of AC units running at once in the summer of 2020 during California’s run of record-high temperatures pushed the state into rolling blackouts. A few days ago, Alberta’s electricity system operator asked Albertans not to plug in their EVs because air conditioner use was straining the electricity supply.

According to the MIT Technology Review, rising incomes, populations and temperatures will triple the number of air conditioners used worldwide, to six billion, by mid-century. How will any warm country have enough power to recharge EVs and run air conditioners at the same time? The Canadian government didn’t say in its news release on the 2035 EV mandate. Will it fund the construction of new fleets of power stations?

The wrong government policy: The government’s announcement made it clear that widespread EV use – more cars – is central to its climate policy. Why not fewer cars and more public transportation? Cities don’t need more cars, no matter the propulsion system. They need electrified buses, subways and trains powered by renewable energy. But the idea of making cities more livable while reducing emissions is apparently an alien concept to this government.

Peak Power Receives $765,000 From Canadian Government to Deploy 117 V1G EV Chargers

Peak Power V1G EV chargers optimize smart charging in Ontario, using Synergy technology and ZEVIP support to manage peak demand, enhance grid capacity, and expand EV infrastructure across mixed-use developments with utility-friendly energy management.

 

Key Points

Peak Power's V1G smart chargers use Synergy tech to cut peak load and grow Ontario EV charging access.

✅ 117 chargers funded by NRCAN's ZEVIP program

✅ Synergy tech shifts load off peak to boost grid capacity

✅ Partners: SWTCH Energy and Signature Electric

 

Peak Power, a Canadian climate tech company with a core focus in energy management and energy storage, announces it has received a $765,000 investment through Natural Resources Canada’s (NRCan) Zero Emission Vehicle Infrastructure Program (ZEVIP) to install 117 V1G chargers as Ontario energy storage push intensifies province-wide planning. The total cost of the project is valued at over $1.6 million.

Peak Power will install the V1G chargers across several mixed-use developments in Ontario. Peak Power’s Synergy technology, which is currently used in the company’s successful Peak Drive EV charging project, will underpin the chargers. The Synergy tech will enable the chargers to draw energy from the grid when it’s most widely available and avoid times of peak demand, similar to emerging EV-to-grid integration pilots now, and can also adjust the flow rate at which the cars are charged. The intelligent chargers will reduce strain on the grid, benefiting utilities and electricity users by increasing grid capacity as well as giving EV drivers more locations to charge their vehicles.

As part of ZEVIP, the project supports the federal government’s goals of accelerating the electrification of Canada’s transportation sector. The 117 chargers will encourage adoption of EVs, as drivers have access to expanded infrastructure for charging, and as Ontario streamlines charging-station builds to accelerate deployments. From the perspective of grid operators, the intelligent nature of the Peak Power software will allow more capacity from the grid without requiring major infrastructure upgrades.

Peak Power will work with partners with deep expertise in EV charging to install the chargers. SWTCH Energy is co-developing the software for the EV chargers with Peak Power, while Signature Electric will install the hardware and supporting infrastructure.

“We’re thrilled to support the Canadian government's electrification goals through smart EV charging,” said Matthew Sachs, COO of Peak Power. “The funding from NRCan will enable us to provide drivers with more options for EV charging, while the smart nature of our Synergy tech in the chargers means grid operators don’t have to worry about capacity restraints when EVs are plugged into the grid, with EV owners selling power back offering additional flexibility too. ZEVIP is critical to greater electrification of the country’s infrastructure, and we’re proud to support the initiative.”

“Happy EV Week, Canada. Our government is making electric vehicles more affordable and charging more accessible where Canadians live, work and play, for example through the Ivy and ONroute charging network that supports travel corridors,” said the Honourable Jonathan Wilkinson, Minister of Natural Resources. “Investing in more EV chargers, like the ones announced today in Ontario, will put more Canadians in the driver’s seat on the road to a net-zero future and help achieve our climate goals.”

"I'm pleased to be announcing the deployment of over 100 Electric Vehicle chargers across Ontario with Peak Power,” said Julie Dabrusin, Parliamentary Secretary to the Minister of Natural Resources and to the Minister of Environment and Climate Change, and Member of Parliament for Toronto-Danforth. “This $765,000 investment by the Government of Canada will allow folks in Toronto and across the province to access the infrastructure they need, as B.C. expands EV charging shows national momentum, to drive an EV while fighting climate change. Happy #EVWeek!”

"Limited access to EV charging infrastructure in high-density mixed-used environments remains a key barrier to widespread EV adoption,” said Carter Li, CEO of SWTCH. “SWTCH’s partnership with Peak Power and Signature Electric to deploy V1G technology to these settings will enhance coordination between energy utilities, building operators, and EV drivers to improve building energy efficiency and access to EV charging infrastructure, with charger rebates in B.C. expanding home and workplace options as well.”

“Signature Electric is proud to be a partner on increasing the availability of localized charging for Canadians,” said Mark Marmer, Owner of Signature Electric. “Together, we can scale EV infrastructure to support Canada’s commitment to achieving net-zero emissions by 2050.”

Enabling storage in Ontario's electricity system

OEB Energy Storage Integration advances DERs and battery storage through CDM guidelines, streamlined connection requirements, IESO-aligned billing, grid modernization incentives, and the Innovation Sandbox, providing regulatory clarity and consumer value across Ontario's electricity system.

 

Key Points

A suite of OEB initiatives enabling storage and DERs via modern rules, cost recovery, billing reforms, and pilots.

✅ Updated CDM guidelines recognize storage at all grid levels.

✅ Standardized connection rules for DERs effective Oct 1, 2022.

✅ Innovation Sandbox supports pilots and temporary regulatory relief.

 

The energy sector is in the midst of a significant transition, where energy storage is creating new opportunities to provide more cost-effective, reliable electricity service. The OEB recognizes it has a leadership role to play in providing certainty to the sector while delivering public value, and a responsibility to ensure that the wider impacts of any changes to the regulatory framework, including grid rule changes, are well understood. 

Accordingly, the OEB has led a host of initiatives to better enable the integration of storage resources, such as battery storage, where they provide value for consumers.

Energy storage integration – our journey 
We have supported the integration of energy storage by:

Incorporating energy storage in Conservation and Demand Management (CDM) Guidelines for electricity distributors. In December 2021, the OEB released updated CDM guidelines that, among other things, recognize storage – either behind-the-meter, at the distribution level or the transmission level – as a means of addressing specific system needs. They also provide options for distributor cost recovery, aligning with broader industrial electricity pricing discussions, where distributor CDM activities also earn revenues from the markets administered by the Independent Electricity System Operator (IESO).
 
Modernizing, standardizing and streamlining connection requirements, as well as procedures for storage and other DERs, to help address Ontario's emerging supply crunch while improving project timelines. This was done through amendments to the Distribution System Code that take effect October 1, 2022, as part of our ongoing DER Connections Review.
 
Facilitating the adoption of Distributed Energy Resources (DERs), which includes storage, to enhance value for consumers by considering lessons from BESS in New York efforts. In March 2021, we launched the Framework for Energy Innovation consultation to achieve that goal. A working group is reviewing issues related to DER adoption and integration. It is expected to deliver a report to the OEB by June 2022 with recommendations on how electricity distributors can assess the benefits and costs of DERs compared to traditional wires and poles, as well as incentives for distributors to adopt third-party DER solutions to meet system needs.
 
Examining the billing of energy storage facilities. A Generic Hearing on Uniform Transmission Rates is underway. In future phases, this proceeding is expected to examine the basis for billing energy storage facilities and thresholds for gross-load billing. Gross-load billing demand includes not just a customer’s net load, but typically any customer load served by behind-the-meter embedded generation/storage facilities larger than one megawatt (or two megawatts if the energy source is renewable).
 
Enabling electricity distributors to use storage to meet system needs. Through a Bulletin issued in August 2020, we gave assurance that behind-the-meter storage assets may be considered a distribution activity if the main purpose is to remediate comparatively poor reliability of service.
 
Offering regulatory guidance in support of technology integration, including for storage, through our OEB Innovation Sandbox, as utilities see benefits across pilot deployments. Launched in 2019, the Innovation Sandbox can also provide temporary relief from a regulatory requirement to enable pilot projects to proceed. In January 2022, we unveiled Innovation Sandbox 2.0, which improves clarity and transparency while providing opportunities for additional dialogue. 
Addressing the barriers to storage is a collective effort and we extend our thanks to the sector organizations that have participated with us as we advanced these initiatives. In that regard, we provided an update to the IESO on these initiatives for a report it submitted to the Ministry of Energy, which is also exploring a hydrogen economy to support decarbonization.

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

US EV Battery Minerals Strategy prioritizes critical minerals with allies, lithium and copper sourcing, battery recycling, and domestic processing, leveraging the Development Finance Corporation to strengthen EV supply chains and reduce reliance on China.

 

Key Points

A US plan to secure critical minerals with allies, boost recycling, and expand domestic processing for EV batteries.

✅ DFC financing for allied lithium and copper projects

✅ Battery recycling to diversify critical mineral supply

✅ Domestic processing with strong environmental standards

 

The United States must work with allies to secure the minerals needed for electric vehicle batteries, addressing pressures on cobalt reserves that could influence supply, and process them domestically in light of environmental and other competing interests, the White House said on Tuesday.

The strategy, first reported by Reuters in late May, will include new funding to expand international investments in electric vehicles (EV) metal projects through the U.S. Development Finance Corporation, as well as new efforts to boost supply from EV battery recycling initiatives.

The U.S. has been working to secure minerals from allied countries, including Canada and Finland, with projects such as Alberta lithium development showing potential. The 250-page report outlining policy recommendations mentioned large lithium supplies in Chile and Australia, the world's two largest producers of the white battery metal.

President Joe Biden's administration will also launch a working group to identify where minerals used in EV batteries and other technologies can be produced and processed domestically.

Securing enough copper, lithium and other raw materials to make EV batteries, amid lithium supply concerns heightened by recent disruptions, is a major obstacle to Biden’s aggressive EV adoption plans, with domestic mines facing extensive regulatory hurdles and environmental opposition.

The White House acknowledged China's role as the world's largest processor of EV metals and said it would expand efforts, including a 100% EV tariff on certain imports, to lessen that dependency.

"The United States cannot and does not need to mine and process all critical battery inputs at home. It can and should work with allies and partners to expand global production and to ensure secure global supplies," it said in the report.

The White House also said the Department of the Interior and others agencies will work to identify gaps in mine permitting laws to ensure any new production "meets strong standards" in terms of both the environment and community input.

The report noted Native American opposition to Lithium Americas Corp's (LAC.TO) Thacker Pass lithium project in Nevada, as well as plans by automaker Tesla Inc (TSLA.O) to produce its own lithium.

The steps come after Biden, who has made fighting climate change and competing with China centerpieces of his agenda, ordered a 100-day review of gaps in supply chains in key areas, including EVs.

Democrats are pushing aggressive climate goals, as Canada EV manufacturing accelerates in parallel, to have a majority of U.S.-manufactured cars be electric by 2030 and every car on the road to be electric by 2040.

As part of the recommendations from four executive branch agencies, Biden is being advised to take steps to restore the country's strategic mineral stockpile and expand funding to map the mineral resources available domestically.

Some of those steps would require the support of Congress, where Biden's fellow Democrats have only slim majorities.

The Energy Department already has $17 billion in authority through its Advanced Technology Vehicles Manufacturing Loan program to fund some investments, and is also launching a lithium-battery workforce initiative to build critical skills.

The program’s administrators will focus on financing battery manufacturers and companies that refine, recycle and process critical minerals, the White House said.

UK Renewable energy projects worth billions stuck on hold

UK Renewable Grid Connection Delays threaten the 2035 zero-carbon electricity target as National Grid queues stall wind and solar projects, investors, and infrastructure, slowing clean energy deployment, curtailing capacity build-out, and risking net-zero progress.

 

Key Points

Prolonged National Grid queues delaying wind and solar connections, jeopardizing the UK's 2035 clean power target.

✅ Up to 15-year waits for grid connections

✅ Over £200bn projects stuck in the queue

✅ Threatens zero-carbon electricity by 2035

 

The UK currently has a 2035 target for 100% of its electricity to be produced without carbon emissions, while Ireland's green electricity progress offers a nearby benchmark within the next four years.

But meeting the target will require a big increase in the number of renewable projects across the country. It is estimated as much as five times more solar and four times as much wind is needed, with growth in UK offshore wind expected to play a key role here.

The government and private investors have spent £198bn on renewable power infrastructure since 2010, alongside European wind investments recorded last year. But now energy companies are warning that significant delays to connect their green energy projects to the system will threaten their ability to bring more green power online.

A new wind farm or solar site can only start supplying energy to people's homes once it has been plugged into the grid.

Energy companies like Octopus Energy, one of Europe's largest investors in renewable energy, say they have been told by National Grid that they need to wait up to 15 years for some connections, even as a new 10 GW contract aims to speed UK grid additions - far beyond the government's 2035 target.

'Longest grid queues in Europe'
There are currently more than £200bn worth of projects sitting in the connections queue, the BBC has calculated.

Around 40% of them face a connection wait of at least a year, according to National Grid's own figures. That represents delayed investments worth tens of billions of pounds, reflecting stalled grid spending that slows renewable rollouts.

"We currently have one of the longest grid queues in Europe," according to Zoisa North-Bond, chief executive of Octopus Energy Generation.

The problem is so many new renewable projects are applying for connections, the grid cannot keep up with required network expansion such as new pylons in Scotland being discussed nationwide.

The system was built when just a few fossil fuel power plants were requesting a connection each year, but now there are 1,100 projects in the queue, a challenge mirrored by U.S. grid hurdles in moving toward 100% renewables today.
