Canada announced plans for a carbon market that could eventually link up with nascent EU and proposed U.S. markets to form a global system for carbon pollution trading.
The local market would provide Canadian companies and individuals an opportunity to reduce their carbon emissions, which are linked to global warming.
"It does so by establishing a price for carbon in Canada — something that has never been done before in this country," Environment Minister Jim Prentice said in a speech to the Economic Club of Canada.
"Anyone wanting to offset their emissions will be able to purchase credits — from small businesses, to individuals, to travelers," he said.
"Every offset credit will represent a real and verified emission reduction, equal to the equivalent of one tonne of carbon dioxide."
Rules and requirements for generating offset credits, including registration of projects and issuance of actual credits and an explanation of how CO2 cuts would be verified, are to be published after a 60-day public consultation.
"Projects that could qualify for offsets span the economy," said Prentice, "from farmers using reduced or no-till techniques to store more carbon dioxide in their fields, to wind turbines producing clean electricity using only the wind, to landfill sites that are able to turn captured methane into usable fuel."
The new system would also target emissions from activities and sectors not covered by planned limits on big industrial polluters, he said.
Under Europe's nascent Emissions Trading System, the EU allocates carbon polluting allowances to member states to meet its obligations under the UN's Kyoto Protocol.
The states then assign quotas to those industries that belch most CO2 into the atmosphere.
Companies that emit less than their allowance can sell the difference on the market to companies that exceed their limits, thus providing a financial carrot to everyone to become greener.
The ETS is touted by supporters as a model for U.S. President Barack Obama's own cap-and-trade scheme and others seeking to cut greenhouse gases and boost green technologies.
However, since its inception it has twice crashed.
In 2007, carbon quotas, set during an initial two-year test period, turned out to be far too generous. After a months-long slump, prices picked up when governments set tougher targets for the 2008-2012 period.
The price of a tonne of carbon dioxide (CO2) or its equivalent again nosedived this month as big European polluters, responding to plummeting demand for their products in a global recession, emitted less.
In December, the United Nations is to hold its 15th climate change conference in Copenhagen.
The summit aims to forge a new global agreement on climate change, to take over from the Kyoto Protocol after it expires in 2012.
"Failure to make progress in Copenhagen is simply not an option," Prentice also commented.
"The consequences are too great, the stakes too high, not to bring to that meeting our best efforts and unwavering resolve," he said.
Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.
Key Points
A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.
✅ 7 micrometer film between electrodes adsorbs water vapor.
✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.
✅ Geobacter optimized via engineered E. coli for mass nanowires.
They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.
This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.
For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.
"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."
The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).
The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.
Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.
The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.
"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.
"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."
The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.
"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.
"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."
Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.
By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).
"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.
"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."
If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.
Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.
"We turned E. coli into a protein nanowire factory," Lovley says.
"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."
Hydro-Quebec Rate Freeze maintains current electricity rates, aligned with Bill 34, inflation indexing, and energy board oversight, delivering rebates to residential, commercial, and industrial customers and projecting nearly $1 billion in savings across Quebec.
Key Points
A Bill 34 policy holding power rates, adding 2020 rebates, and indexing 2021-2024 rates to inflation for Quebec customers.
✅ 2020-21 rates frozen; savings near $1B over five years.
✅ 2021-2024 rates index to inflation; five-year reviews after 2025.
Hydro-Quebec Distribution will not file a rate adjustment application with the province’s energy board this year, amid a class-action lawsuit alleging customers were overcharged.
In a statement released on Friday the Crown Corporation said it wants current electricity rates to be maintained for another year, as pandemic-driven demand pressures persist, starting April 1. That is consistent with the recently tabled Bill 34, and echoes Ontario legislation to lower electricity rates in its aims, which guarantees lower electricity rates for Quebecers.
The bill also provides a $500 million rebate in 2020, similar to a $535 million refund previously issued, half of which will go to residential customers while $190 million will go to commercial customers and another $60 million to industrial ones.
Hydro-Quebec said the 2020-21 rate freeze will generate savings of nearly $1 billion for its clients over the next five years, even as Manitoba Hydro scales back increases in a different market.
Bill 34, which was tabled in June, also proposes to set rates based on inflation for the years 2021 to 2024, contrasting with Ontario rate increases over the same period. After 2025 Hydro-Quebec would have to ask the energy board to set new rates every five years, as opposed to the current annual system, while BC Hydro is raising rates by comparison.
Hydro-Québec Carillon Refurbishment delivers a $750M hydropower modernization, replacing six turbines and upgrading civil works, water passageways, and grid equipment to extend run-of-river, renewable energy output for peak demand near Montréal.
Key Points
A $750M project replacing six units and upgrading civil, water and electrical systems to supply power for 50 years.
✅ Replaces six generating units with Andritz turbines.
✅ Upgrades civil works, water passageways, and electrical gear.
✅ Extends run-of-river output for 50 years; boosts peak supply.
Hydro-Québec will invest $750 million to refurbish its Carillon generating station with a major powerhouse upgrade that will mainly replace six generating units. The investment also covers the cost of civil engineering work, including making adjustments to water passageways, upgrading electrical equipment and replacing the station roof. Work will start in 2021, aligning with Hydro-Québec's capacity expansion plans for 2021, and continue until 2027.
Carillon generating station is a run-of-river power plant consisting of 14 generating units with a total installed capacity of 753 MW. Built in the early 1960s, it is a key part of Hydro-Québec's hydroelectric generating fleet, which includes the La Romaine complex as well. The station is close to the greater Montréal area and feeds power into the grid to support industrial demand growth during peak consumption periods.
The selected supplier, turbine manufacturer Andritz, has been asked to maximize the project's economic spinoffs in Québec, as Canada continues investing in new turbines across the country to modernize assets. Once the work is completed, the new generating units will be able to provide clean, renewable energy, supporting Hydro-Québec's strategy to reduce fossil fuel reliance for the next 50 years.
"Carillon generating station is a symbol of our hydroelectric development and plays a strategic role in our production fleet. However, most of the generating units' main components date back to the station's original construction from 1959 to 1962. Hydropower generating stations have long service lives - with this refurbishment, Carillon will be producing clean renewable energy for decades to come." said David Murray, Chief Innovation Officer and President, Hydro-Québec Production.
"In light of today's economic situation, this is an important announcement that clearly reaffirms Hydro-Québec's role in relaunching Québec's economy and strengthening interprovincial electricity partnerships that open new markets. Over 600,000 hours of work will be required for everything from the engineering work to component assembly, creating many new high-quality skilled jobs for Québec industries."
Clean Energy Tax Incentives could expand under Democratic proposals, including ITC, PTC, and EV tax credits, boosting renewable energy, energy storage, and grid modernization within a broader infrastructure package influenced by Green New Deal goals.
Key Points
Federal incentives like ITC, PTC, and EV credits that cut costs and speed renewables, storage, and grid upgrades.
✅ Proposes permanence for ITC, PTC, and EV tax credits
✅ Could accelerate solar, wind, storage, and grid upgrades
✅ Passage depends on bipartisan infrastructure compromise
The 115th U.S. Congress has not even adjourned for the winter, and already a newly resurgent Democratic Party is making demands that reflect its majority status in the U.S. House come January.
Climate appears to be near the top of the list. Last Thursday, Senator Chuck Schumer (D-NY), the Democratic Leader in the Senate, sent a letter to President Trump demanding that any infrastructure package taken up in 2019 include “policies and funding to transition to a clean energy economy and mitigate the risks that the United States is already facing due to climate change.”
And in a list of policies that Schumer says should be included, the top item is “permanent tax incentives for domestic production of clean electricity and storage, energy efficient homes and commercial buildings, electric vehicles, and modernizing the electric grid.”
In concrete terms, this could mean an extension of the Investment Tax Credit (ITC) for solar and energy storage, the Production Tax Credit (PTC) for wind and the federal electric vehicle (EV) tax credit program as well.
Pressure from the Left
This strong statement on climate change, clean energy and infrastructure investment comes as at least 30 incoming members of the U.S. House of Representatives have signed onto a call for the creation of a committee to explore a “Green New Deal” and to move the nation to 100% renewable energy by 2030.*
It also comes as Schumer has come under fire by activists for rumors that he plans to replace Senator Maria Cantwell (D-Washington) with coal state Democrat Joe Manchin (D-West Virginia) as the top Democrat on the Senate Energy and Natural Resources Committee.
As such, one possible way to read these moves is that centrist leaders like Schumer are responding to pressure from an energized and newly elected Left wing of the Democratic Party. It is notable that Schumer’s program includes many of the aims of the Green New Deal, while avoiding any explicit use of that phrase.
Implications of a potential ITC extension
The details of levels and timelines are important here, particularly for the ITC.
The ITC was set to expire at the end of 2016, but was extended in legislative horse-trading at the end of 2015 to a schedule where it remains at 30% through the end of 2019 and then steps down for the next three years, and disappears entirely for residential projects. Since that extension the IRS has issued guidance around the use of co-located energy storage, as well as setting a standard under which PV projects can claim the ITC for the year that they begin construction.
This language around construction means that projects can start work in 2019, complete in 2023 and still claim the 30% ITC, and this may be why we at pv magazine USA are seeing an unprecedented boom in project pipelines across the United States.
Of course, if the ITC were to become permanent some of those projects would be pushed out to later years. But as we saw in 2016, despite an extension of the ITC many projects were still completed before the deadline, leading to the largest volume of PV installed in the United States in any one year to date.
This means that if the ITC were extended by the end of 2020, we could see the same thing all over again – a boom in projects created by the expected sunset, and then after a slight lull a continuation of growth.
Or it is possible that a combination of raw economics, increased investor and utility interest, and accelerating renewable energy mandates will cause solar growth rates to continue every year, and that any changes in the ITC will only be a bump against a larger trend.
While the basis for expiration of the EV tax credit is the number of vehicles sold, not any year, both the battery storage and EV industries, which many see at an inflection point, could see similar effects if the ITC and EV tax credits are made permanent.
Will consensus be reached?
It is also unclear that any such infrastructure package will be taken up by Republicans, or that both parties will be able to come to a compromise on this issue. While the U.S. Congress passed an infrastructure bill in 2017, given the sharp and growing differences between the two parties, and divergent trade approaches such as the 100% tariff on Chinese-made EVs, it is not clear that they will be able to come to a meaningful compromise during the next two years.
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
Iran-Iraq Electricity Cooperation advances with power grid synchronization, cross-border energy trade, 400-kV transmission lines, and education partnerships, boosting grid reliability, infrastructure investment, and electricity exports between Tehran and Baghdad for improved supply and stability.
Key Points
A bilateral initiative to synchronize grids, expand networks, and sustain electricity exports, improving reliability.
✅ 400-kV Amarah-Karkheh line enables synchronized operations.
✅ Extends electricity export contracts to meet Iraq demand.
✅ Enhances grid reliability, training, and infrastructure investment.
Aradakanian has focused his one-day visit to Iraq on discussions pertaining to promoting bilateral collaboration between the two neighboring nations in the field of electricity, grid development deals and synchronizing power grid between Tehran and Baghdad, cooperating in education, and expansion of power networks.
He is also scheduled to meet with Iraqi top officials in a bid to boost cooperation in the relevant fields.
Back in December 2019, Ardakanian announced that Iran will continue exports of electricity to Iraq by renewing earlier contract as it is supplying about 40% of Iraq's power today.
"Iran has signed a 3-year-long cooperation agreement with Iraq to help the country's power industry in different aspects. The documents states at its end that we will export electricity to Iraq as far as they need," Ardakanian told FNA on December 9, 2019.
The contract to "export Iran's electricity" to Iraq will be extended, he added.
Ardakanian also said that Iran and Iraq's power grids have become synchronized in a move that supports Iran's regional power hub plans since a month ago.
In 2004 Iran started selling electricity to Iraq. Iran electricity exports to the western neighbor are at its highest level of 1,361 megawatts per day now, as the country weighs summer power sufficiency ahead of peak demand.
The new Amarah-Karkheh 400-KV transmission line stretching over 73 kilometers, is now synchronized to provide electricity to both countries, reflecting regional power export trends as well. It also paves the way for increasing export to power-hungry Iraq in the near future.
With synchronization of the two grids, the quality of electricity in Iraq will improve as the country explores nuclear power options to tackle shortages.
According to official data, 82% of Iraq's electricity is generated by thermal power plants that use gas as feedstock, while Iran is converting thermal plants to combined cycle to save energy. This is expected to reach 84% by 2027.
