CO2 Removal Technologies address climate change via negative emissions, including carbon capture, reforestation, soil carbon, biochar, BECCS, DAC, and mineralization, helping meet Paris Agreement targets while managing costs, land use, and infrastructure demands.

Key Points

Methods to extract or sequester atmospheric CO2, combining natural and engineered approaches to limit warming.

✅ Includes reforestation, soil carbon, biochar, BECCS, DAC, mineralization

✅ Balances climate goals with costs, land, energy, and infrastructure

✅ Key to Paris Agreement targets under 1.5-2.0 °C warming

The world is, on average, 1.1 degrees Celsius warmer today than it was in 1850. If this trend continues, our planet will be 2 – 3 degrees hotter by the end of this century, according to the Intergovernmental Panel on Climate Change (IPCC).

The main reason for this temperature rise is higher levels of atmospheric carbon dioxide, which cause the atmosphere to trap heat radiating from the Earth into space. Since 1850, the proportion of CO2 in the air has increased, with record greenhouse gas concentrations documented, from 0.029% to 0.041% (288 ppm to 414 ppm).

This is directly related to the burning of coal, oil and gas, which were created from forests, plankton and plants over millions of years. Back then, they stored CO2 and kept it out of the atmosphere, but as fossil fuels are burned, that CO2 is released. Other contributing factors include industrialized agriculture and slash-and-burn land clearing techniques, and emissions from SF6 in electrical equipment are also concerning today.

Over the past 50 years, more than 1200 billion tons of CO2 have been emitted into the planet's atmosphere — 36.6 billion tons in 2018 alone, though global emissions flatlined in 2019 before rising again. As a result, the global average temperature has risen by 0.8 degrees in just half a century.

Atmospheric CO2 should remain at a minimum
In 2015, the world came together to sign the Paris Climate Agreement which set the goal of limiting global temperature rise to well below 2 degrees — 1.5 degrees, if possible.

The agreement limits the amount of CO2 that can be released into the atmosphere, providing a benchmark for the global energy transition now underway. According to the IPCC, if a maximum of around 300 billion tons were emitted, there would be a 50% chance of limiting global temperature rise to 1.5 degrees. If CO2 emissions remain the same, however, the CO2 'budget' would be used up in just seven years.

According to the IPCC's report on the 1.5 degree target, negative emissions are also necessary to achieve the climate targets.

Using reforestation to remove CO2
One planned measure to stop too much CO2 from being released into the atmosphere is reforestation. According to studies, 3.6 billion tons of CO2 — around 10% of current CO2 emissions — could be saved every year during the growth phase. However, a study by researchers at the Swiss Federal Institute of Technology, ETH Zurich, stresses that achieving this would require the use of land areas equivalent in size to the entire US.

Reforestation has potential to tackle the climate crisis by capturing CO2. But it would require a large amount of space

More humus in the soil
Humus in the soil stores a lot of carbon. But this is being released through the industrialization of agriculture. The amount of humus in the soil can be increased by using catch crops and plants with deep roots as well as by working harvest remnants back into the ground and avoiding deep plowing. According to a study by the German Institute for International and Security Affairs (SWP) on using targeted CO2 extraction as a part of EU climate policy, between two and five billion tons of CO2 could be saved with a global build-up of humus reserves.

Biochar shows promise
Some scientists see biochar as a promising technology for keeping CO2 out of the atmosphere. Biochar is created when organic material is heated and pressurized in a zero or very low-oxygen environment. In powdered form, the biochar is then spread on arable land where it acts as a fertilizer. This also increases the amount of carbon content in the soil. According to the same study from the SWP, global application of this technology could save between 0.5 and two billion tons of CO2 every year.

Storing CO2 in the ground
Storing CO2 deep in the Earth is already well-known and practiced on Norway's oil fields, for example. However, the process is still controversial, as storing CO2 underground can lead to earthquakes and leakage in the long-term. A different method is currently being practiced in Iceland, in which CO2 is sequestered into porous basalt rock to be mineralized into stone. Both methods still require more research, however, with new DOE funding supporting carbon capture, utilization, and storage.

Capturing CO2 to be held underground is done by using chemical processes which effectively extract the gas from the ambient air, and some researchers are exploring CO2-to-electricity concepts for utilization. This method is known as direct air capture (DAC) and is already practiced in other parts of Europe.  As there is no limit to the amount of CO2 that can be captured, it is considered to have great potential. However, the main disadvantage is the cost — currently around €550 ($650) per ton. Some scientists believe that mass production of DAC systems could bring prices down to €50 per ton by 2050. It is already considered a key technology for future climate protection.

Carbon capture facilities are still very expensive and take up a huge amount of space

Another way of extracting CO2 from the air is via biomass. Plants grow and are burned in a power plant to produce electricity. CO2 is then extracted from the exhaust gas of the power plant and stored deep in the Earth, with new U.S. power plant rules poised to test such carbon capture approaches.

The big problem with this technology, known as bio-energy carbon capture and storage (BECCS) is the huge amount of space required. According to Felix Creutzig from the Mercator Institute on Global Commons and Climate Change (MCC) in Berlin, it will therefore only play "a minor role" in CO2 removal technologies.

CO2 bound by rock minerals
In this process, carbonate and silicate rocks are mined, ground and scattered on agricultural land or on the surface water of the ocean, where they collect CO2 over a period of years. According to researchers, by the middle of this century it would be possible to capture two to four billion tons of CO2 every year using this technique. The main challenges are primarily the quantities of stone required, and building the necessary infrastructure. Concrete plans have not yet been researched.

Not an option: Fertilizing the sea with iron
The idea is use iron to fertilize the ocean, thereby increasing its nuturient content, which would allow plankton to grow stronger and capture more CO2. However, both the process and possible side effects are very controversial. "This is rarely treated as a serious option in research," concludes SWP study authors Oliver Geden and Felix Schenuit.

Canada Net-Zero Transition unites energy workers, R&D, and clean tech to decarbonize steel and cement with hydrogen, scale renewables, and build hybrid storage, delivering a just transition that strengthens communities and the economy.

Key Points

A national plan to reach net-zero by 2050 via renewables, hydrogen, decarbonization, and a just transition for workers.

✅ Hydrogen for steel and cement decarbonization

✅ Hybrid energy storage and clean tech R&D

✅ Just transition pathways for energy workers

Except for an isolated pocket of skeptics, there is now an almost universal acceptance that climate change is a global emergency that demands immediate and far-reaching action to defend our home and future generations. Yet in Canada we remain largely focused on how the crisis divides us rather than on the potential for it to unite us, despite nationwide progress in electricity decarbonization efforts.

It’s not a case of fossil-fuel industry workers versus the rest, or Alberta versus British Columbia where bridging the electricity gap could strengthen cooperation. We are all in this together. The challenge now is how to move forward in a way that leaves no one behind.

The fossil fuel industry has been — and continues to be — a key driver of Canada’s economy. Both of us had successful careers in the energy sector, but realized, along with an increasing number of energy workers, that the transition we need to cope with climate change could not be accomplished solely from within the industry.

Even as resource companies innovate to significantly reduce the carbon burden of each barrel, the total emission of greenhouse gases from all sources continues to rise. We must seize the opportunity to harness this innovative potential in alternative and complementary ways, mobilizing research and development, for example, to power carbon-intensive steelmaking and cement manufacture from hydrogen or to advance hybrid energy storage systems and decarbonizing Canada's electricity grid strategies — the potential for cross-over technology is immense.

The bottom line is inescapable: we must reach net-zero emissions by 2050 in order to prevent runaway global warming, which is why we launched Iron & Earth in 2016. Led by oilsands workers committed to increasingly incorporating renewable energy projects into our work scope, our non-partisan membership now includes a range of industrial trades and professions who share a vision for a sustainable energy future for Canada — one that would ensure the health and equity of workers, our families, communities, the economy, and the environment.

Canada Wind Energy Costs are plunging as renewable energy auctions, CfD contracts, and efficient turbines drive prices to 2-4 cents/kWh across Alberta and Saskatchewan, outcompeting grid power via competitive bidding and improved capacity factors.

Key Points

Averaging 2-4 cents/kWh via auctions, CfD support, and bigger turbines, wind is now cost-competitive across Canada.

✅ Alberta CfD bids as low as 3.9 cents/kWh.

✅ Turbine outputs rose from 1 MW to 3.3 MW per tower.

✅ Competitive auctions cut costs ~70% over nine years.

It's taken a decade of technological improvement and a new competitive bidding process for electrical generation contracts, but wind may have finally come into its own as one of the cheapest ways to create power.

Ten years ago, Ontario was developing new wind power projects at a cost of 28 cents per kilowatt hour (kWh), the kind of above-market rate that the U.K., Portugal and other countries were offering to try to kick-start development of renewables. 

Now some wind companies say they've brought generation costs down to between 2 and 4 cents — something that appeals to provinces that are looking to significantly increase their renewable energy deployment plans.

The cost of electricity varies across Canada, by province and time of day, from an average of 6.5 cents per kWh in Quebec to as much as 15 cents in Halifax.

Capital Power, an Edmonton-based company, recently won a contract for the Whitla 298.8-megawatt (MW) wind project near Medicine Hat, Alta., with a bid of 3.9 cents per kWh, at a time when three new solar facilities in Alberta have been contracted at lower cost than natural gas, underscoring the trend. That price covers capital costs, transmission and connection to the grid, as well as the cost of building the project.

Jerry Bellikka, director of government relations, said Capital Power has been building wind projects for a decade, in the U.S., Alberta, B.C. and other provinces. In that time the price of wind generation equipment has been declining continually, while the efficiency of wind turbines increases.

Increased efficiency

"It used to be one tower was 1 MW; now each turbine generates 3.3 MW. There's more electricity generated per tower than several years ago," he said.

One wild card for Whitla may be steel prices — because of the U.S. and Canada slapping tariffs on one other's steel and aluminum products. Whitla's towers are set to come from Colorado, and many of the smaller components from China.

Canada introduces new surtaxes to curb flood of steel imports

"We haven't yet taken delivery of the steel. It remains to be seen if we are affected by the tariffs." Belikka said.

Another company had owned the site and had several years of meteorological data, including wind speeds at various heights on the site, which is in a part of southern Alberta known for its strong winds.

But the choice of site was also dependent on the municipality, with rural Forty Mile County eager for the development, Belikka said.

Alberta aims for 30% electricity from wind by 2030

Alberta wants 30 per cent of its electricity to come from renewable sources by 2030 and, as an energy powerhouse, is encouraging that with a guaranteed pricing mechanism in what is otherwise a market-bidding process.

While the cost of generating energy for the Alberta Electric System Operator (AESO) fluctuates hourly and can be a lot higher when there is high demand, the winners of the renewable energy contracts are guaranteed their fixed-bid price.

The average pool price of electricity last year in Alberta was 5 cents per kWh; in boom times it rose to closer to 8 cents. But if the price rises that high after the wind farm is operating, the renewable generator won't get it, instead rebating anything over 3.9 cents back to the government.

On the other hand, if the average or pool price is a low 2 cents kWh, the province will top up their return to 3.9 cents.

This contract-for-differences (CfD) payment mechanism has been tested in renewable contracts in the U.K. and other jurisdictions, including some U.S. states, according to AESO.

Competitive bidding in Saskatchewan

In Saskatchewan, the plan is to double its capacity of renewable electricity, to 50 per cent of generation capacity, by 2030, and it uses an open bidding system between the private sector generator and publicly owned SaskPower.

In bidding last year on a renewable contract, 15 renewable power developers submitted bids, with an average price of 4.2 cents per kWh.

One low bidder was Potentia with a proposal for a 200 MW project, which should provide electricity for 90,000 homes in the province, at less than 3 cents kWh, according to Robert Hornung of the Canadian Wind Energy Association.

"The cost of wind energy has fallen 70 per cent in the last nine years," he says. "In the last decade, more wind energy has been built than any other form of electricity."

Ontario remains the leading user of wind with 4,902 MW of wind generation as of December 2017, most of that capacity built under a system that offered an above-market price for renewable power, put in place by the previous Liberal government.

In June of last year, the new Conservative government of Doug Ford halted more than 700 renewable-energy projects, one of them a wind farm that is sitting half-built, even as plans to reintroduce renewable projects continue to advance.

The feed-in tariff system that offered a higher rate to early builders of renewable generation ended in 2016, but early contracts with guaranteed prices could last up to 20 years.

Hornung says Ontario now has an excess of generating capacity, as it went on building when the 2008-9 bust cut market consumption dramatically.

But he insists wind can compete in the open market, offering low prices for generation when Ontario needs new  capacity.

"I expect there will be competitive processes put in place. I'm quite confident wind projects will continue to go ahead. We're well positioned to do that."

Maritime Link Subsea Cable enables HVDC grid interconnection across the Cabot Strait, linking Nova Scotia with Newfoundland and Labrador to import Muskrat Falls hydroelectric power and expand renewable energy integration and reliability.

Key Points

A 170-km HVDC subsea link connecting Nova Scotia and Newfoundland and Labrador for Muskrat Falls power and renewables

✅ 170-km HVDC subsea route across Cabot Strait

✅ Connects Nova Scotia and Newfoundland and Labrador grids

✅ Enables Muskrat Falls hydro and renewable energy trade

The longest sub-sea electricity cable in North America now connects Nova Scotia and Newfoundland and Labrador, according to the company behind the $1.7-billion Maritime Link project.  

The first of the project's two high-voltage power transmission cables was anchored at Point Aconi, N.S., on Sunday. 

The 170-kilometre long cable across the Cabot Strait will connect the power grids in the two provinces. The link will allow power to flow between the two provinces, as demonstrated by its first electricity transfer milestone, and bring to Nova Scotia electricity generated by the massive Muskrat Falls hydroelectric project in Labrador. 

Ultimately, the Maritime Link will help Nova Scotia reach the renewable energy goals set out by the federal government, said Rick Janega, the president and CEO of Emera Newfoundland and Labrador, whose subsidiary owns the Maritime Link.

"If not for the Maritime Link then really the province would not have the ability to meet those requirements because we're pretty much tapped out of all the hydro in province and all the wind generation without creating new interconnections like the Maritime Link," said Janega. 

Not everyone wanted the link 

Fishermen in Cape Breton had objected to the Maritime Link. They were concerned about how the undersea cable might affect fish in the area. 

The laying of the cable and other construction closed a three-kilometre long and 600-metre wide swath of ocean bottom to fishermen for the entire 2017 lobster season.  

But the company came to an agreement to compensate a group of 60 Cape Breton lobster and crab fishermen affected by the project this season. The terms of the compensation deal were not released. 

Long cable, big job

The transmission cable runs northwest of the Marine Atlantic ferry route between North Sydney, N.S., and Port aux Basques, N.L. 

Installation of the second cable is set to begin in June, a major step comparable to BC Hydro's Site C transmission milestone achieved recently. The entire link should be completed by late 2017 and should go into full service by January 2018.

"We're quite confident as soon as the Maritime Link is in service there will be energy transactions between Nova Scotia Power and Newfoundland Hydro. Both utilities have already identified opportunities to save money and exchange energy between the two provinces," said Janega.

That's two years before power is expected to flow from the Muskrat Falls hydro project. The Labrador-based power generating facility has been hampered by delays.

Those kinds of transmission project delays are expected for such a large project, said Janega, and won't stop the Maritime Link from being used. 

"With the Maritime Link going in service this year providing Nova Scotia the opportunity that it needs to be able to reach carbon reductions and to adapt to climate change and to increase renewable energy content and we're very pleased to be at this state today," said Janega.

UK Energy Switching Surge sees 600,000 customers change suppliers in October, driven by competition, the Energy Switch Guarantee, and better tariffs, with Electralink's DTN supporting customer switching and Ofgem oversight.

Key Points

A rise in UK customers switching electricity suppliers in October, driven by competition and the Energy Switch Guarantee.

✅ 600,000 switches recorded in October

✅ 32% moved to small and mid-tier suppliers

✅ Energy Switch Guarantee assures simple, safe transfers

More than 600,000 customers took steps to save on their energy bills this winter by switching electricity provider in October, as forecasts such as a 16% bill decrease in April offer further encouragement, the latest figures from Energy UK reveal.

A third (32 per cent) of those changing providers in October moved to small and mid-tier suppliers.

Regional markets have seen changes too, including Irish electricity price increases that highlight wider cost pressures.

With recent research showing that that nine in ten energy switchers were happy with the process of changing suppliers and with the reassurance provided by the Energy Switch Guarantee - a series of commitments ensuring switches are simple, speedy and safe - and amid MPs proposing price restrictions to protect consumers, more and more customers are now confident when looking to move.

Lawrence Slade, chief executive of Energy UK said: 'Switching continues to surge with over 600,000 customers changing supplier to find a better deal last month. Many more will have made savings by checking they are on the best deal with their current supplier. It only takes a few minutes to do this and with over 55 suppliers across the market, there's never been more competition or choice.'

Around 75 per cent of the market are signatories of the Guarantee. This includes: British Gas, Bulb Energy, E.ON, EDF Energy, First Utility, Flow Energy, npower, Octopus Energy, Pure Planet, Sainsbury's Energy, Scottish Power, So Energy and Tonik Energy.

The switching data is supplied by Electralink who provides a secure service to transfer data between the electricity market participants. The company operates the Data Transfer Network (DTN) which underpins customer switching, meter interoperability and other business processes critical to a competitive electricity market, where knowing where your electricity comes from can support informed choices.

The data referenced in these reports is since our collection of data only and is for electricity only.

These figures do not include internal electricity switching, and statistics on this from the larger suppliers and on Standard Variable Tariffs can be viewed on the Ofgem website, while ministers consider ending the gas-electricity price link to reduce bills.

Ukraine's EU Energy Integration aims for ENTSO-E synchronization, electricity market liberalization, EU Green Deal alignment, energy efficiency upgrades, hydrogen development, and streamlined grid connections to accelerate reform, market pricing, and sustainable growth.

Key Points

Ukraine's EU Energy Integration syncs with ENTSO-E, liberalizes power markets, and aligns with the EU Green Deal.

✅ ENTSO-E grid synchronization and cross-border trade readiness

✅ Electricity market liberalization and market-based pricing

✅ EU Green Deal alignment: efficiency, hydrogen, coal regions

Ukraine's goal in the energy sector is to ensure the maximum integration of energy markets with EU markets, and in line with the EU plan to dump Russian energy that is reshaping the region, synchronization of Ukraine's integrated energy system with ENTSO-E while leaning on electricity imports as needed to maintain stability. Prime Minister Denys Shmyhal emphasized in his statement at the Fourth Ukraine Reform Conference underway through July 7-8 in Vilnius, the Republic of Lithuania.

The Head of Government presented a plan of reforms in Ukraine until 2030. In particular, energy sector reform and environmental protection, according to the PM, include the liberalization of the electricity market, with recent amendments to the market law guiding implementation, the simplification of connection to the electrical grid system and the gradual transition to market electricity prices, alongside potential EU emergency price measures under discussion, and the monetization of subsidies for vulnerable groups.

"Ukraine shares and fully supports the EU's climate ambitions and aims to synchronize its policies in line with the EU Green Deal, including awareness of Hungary's energy alignment with Russia to ensure coherent regional planning. The interdepartmental working group has determined priority areas for cooperation with the European Union: energy efficiency, hydrogen, transformation of coal regions, waste management," said the Prime Minister.

According to Denys Shmyhal, Ukraine has supported the EU's climate ambitions to move towards climate-neutral development by 2050 within the framework of the European Green Deal and should become an integral part of it in order not only to combat the effects of climate change in synergy with the EU but, as the country prepares for winter energy challenges and strengthens resilience, within the economic strategy development aimed to enhance security and create new opportunities for Ukrainian business, with continued energy security support from partners bolstering implementation.
