Cement-Based Conductive Composite transforms concrete into power by energy harvesting via triboelectric nanogenerator action, carbon fibers, and built-in capacitors, enabling net-zero buildings and self-sensing structural health monitoring from footsteps, wind, rain, and waves.

Key Points

A carbon fiber cement that harvests and stores energy as electricity, enabling net-zero, self-sensing concrete.

✅ Uses carbon fibers to create a conductive concrete matrix

✅ Acts as a triboelectric nanogenerator and capacitor

✅ Enables net-zero, self-sensing structural health monitoring

Engineers from South Korea have invented a cement-based composite that can be used in concrete to make structures that generate and store electricity through exposure to external mechanical energy sources like footsteps, wind, rain and waves, and even self-powering roads concepts.

By turning structures into power sources, the cement will crack the problem of the built environment consuming 40% of the world’s energy, complementing vehicle-to-building energy strategies across the sector, they believe.

Building users need not worry about getting electrocuted. Tests showed that a 1% volume of conductive carbon fibres in a cement mixture was enough to give the cement the desired electrical properties without compromising structural performance, complementing grid-scale vanadium flow batteries in the broader storage landscape, and the current generated was far lower than the maximum allowable level for the human body.

Researchers in mechanical and civil engineering from from Incheon National University, Kyung Hee University and Korea University developed a cement-based conductive composite (CBC) with carbon fibres that can also act as a triboelectric nanogenerator (TENG), a type of mechanical energy harvester.

They designed a lab-scale structure and a CBC-based capacitor using the developed material to test its energy harvesting and storage capabilities, similar in ambition to gravity storage approaches being scaled.

“We wanted to develop a structural energy material that could be used to build net-zero energy structures that use and produce their own electricity,” said Seung-Jung Lee, a professor in Incheon National University’s Department of Civil and Environmental Engineering, noting parallels with low-income housing microgrids in urban settings.

“Since cement is an indispensable construction material, we decided to use it with conductive fillers as the core conductive element for our CBC-TENG system,” he added.

The results of their research were published this month in the journal Nano Energy.

Apart from energy storage and harvesting, the material could also be used to design self-sensing systems that monitor the structural health and predict the remaining service life of concrete structures without any external power, which is valuable in industrial settings where hydrogen-powered port equipment is being deployed.

“Our ultimate goal was to develop materials that made the lives of people better and did not need any extra energy to save the planet. And we expect that the findings from this study can be used to expand the applicability of CBC as an all-in-one energy material for net-zero energy structures,” said Prof. Lee, pointing to emerging circular battery recycling pathways for net-zero supply chains.

Publicising the research, Incheon National University quipped: “Seems like a jolting start to a brighter and greener tomorrow!”

Canada Electric Vehicle Adoption is accelerating as EV range doubles, fast-charging networks expand along the Trans-Canada Highway, and drivers shift from internal combustion to clean transportation to cut emissions and support climate goals.

Key Points

Canada Electric Vehicle Adoption reflects rising EV uptake, longer range, and expanding fast-charging infrastructure.

✅ Average EV range in Canada has nearly doubled in six years.

✅ Fast chargers expanding along Trans-Canada and major corridors.

✅ Gasoline and diesel demand projected to fall sharply by 2040.

As green technology for vehicles continues to grow in popularity, with a recent EV event in Regina drawing strong interest, attendance at a seminar in southern Alberta Wednesday showed plenty people want to switch to electric.

FreeU, a series of informal education sessions about electric power and climate change, including electricity vs hydrogen considerations, helped participants to learn more about the world-changing technology.

Also included at the talks was a special electric vehicle meet up, where people interested in the technology could learn about it, first hand, from drivers who've already gone gasless despite EV shortages and wait times in many regions.

"That's kind of a warning or a caution or whatever you want to call it. You get addicted to these things and that's a good example."

James Byrne, a professor of geography at the University of Lethbridge says people are much more willing these days to look to alternatives for their driving needs, though cost remains a key barrier for many.

"The internal combustion engine is on its way out. It served us well, but electric vehicles are much cleaner, aligning with Canada's EV goals set by policymakers today."

According to the Canada Energy Regulator, the average range of electric vehicles in Canada have almost doubled in the past six years.

The agency also predicts a massive decrease in gasoline and diesel use (359 petajoules and 92 petajoules respectively) in Canada by 2040. In that same timeframe, electricity use, even though fossil-fuel share remains, is expected to increase by 118 petajoules.

The country is also developing its network of fast charging stations, so running out of juice will be less of a worry for prospective buyers, even as 2035 EV mandate debate continues among analysts.

"They have just about Interstate in the U.S. covered," Marshall said. "In Canada, they're building out the [Trans-Canada Highway] right now."

BC Hydro Clean Energy Champions highlights Vancouver's Bloedel Conservatory electrification with a massive heat pump, clean electricity, LED lighting, deep energy efficiency, and 90% greenhouse gas reductions advancing climate action across buildings and industry.

Key Points

A BC Hydro program honoring clean electricity adoption in homes, transport, and industry to replace fossil fuels.

✅ Vancouver's Bloedel Conservatory cut GHGs by 90% with a heat pump

✅ LEDs and electrification boost efficiency, comfort, and reliability

✅ Nominations open for residents, businesses, and Indigenous groups

The City of Vancouver has been selected as BC Hydro’s first Clean Energy Champion for energy efficient upgrades made at the Bloedel Conservatory that cut greenhouse gas emissions by 90 per cent, a meaningful step given concerns about 2050 greenhouse gas targets in B.C.

BC Hydro’s Clean Energy Champions program is officially being launched today to recognize residents, businesses, municipalities, Indigenous and community groups across B.C. that have made the choice to switch from using fossil fuels to using clean electricity in three primary areas: homes and buildings, transportation, and industry, even as drought challenges power generation in B.C. The City of Vancouver is being recognized as the first champion for demonstrating its commitment to using clean energy, including power from projects like Site C's electricity, to fight climate change at its landmark Bloedel Conservatory.

Earlier this year, the City of Vancouver installed a large air source heat pump at Bloedel Conservatory – more than 50 times the size of a heat pump used in a typical B.C. home – that uses electricity instead of natural gas to heat and cool the dome's interior, which is home to more than 500 exotic plants and flowers, and 100 exotic birds, aligning with citywide debates such as Vancouver’s reversal on gas appliances policy. It is the biggest heat pump the City of Vancouver has ever installed, with 210 tonnes of cooling capacity.

A heat pump that provides cooling in the summer and heating in the winter, helping reduce reliance on wasteful air conditioning that can drive up energy bills, is ideal for the conservatory, as its dome is completely made of glass, which can be challenging for temperature regulation. While the dome experiences a lot of heat loss in the colder months, its need for cooling in warmer weather is even greater to ensure the safety of the wildlife and plants that call it home.

The clean energy upgrades do not end there though. All lighting in the building has been upgraded to energy-efficient LEDs, reflecting conservation themes highlighted by 2018 Earth Hour electricity use discussions, and outside colour-changing LEDs now surround the perimeter and light up the dome at night.

BC Hydro is calling for nominations from B.C. residents, businesses, municipalities or Indigenous and community groups that have taken steps to lower their carbon footprint and adopt new clean energy technologies, and continues to support customers through programs like its winter payment plan during colder months. If you or someone you know is a Clean Energy Champion, nominate them at bchydro.com/cleanenergychampions.

NECEC Clean Energy Connect advances with Maine DEP permits, Hydro-Québec contracts, and rigorous transmission line mitigation, including tapered vegetation, culvert upgrades, and forest conservation, delivering low-carbon power, broadband fiber, and projected ratepayer savings.

Key Points

A Maine transmission project delivering Hydro-Québec power with strict DEP mitigation, lower bills, and added broadband.

✅ DEP permits mandate tapered vegetation, culvert upgrades, land conservation

✅ Hydro-Québec to supply 9.55 TWh/yr via MA contracts; bill savings 2-4%

✅ Added broadband fiber in Somerset and Franklin; local tax benefits

The Maine DEP reviewed the Clean Energy Connect project for more than two years, while regional interest in cross-border transmission continued to grow, before issuing permits that included additional environmental mitigation elements.

"Collectively, the requirements of the permit require an unprecedented level of environmental protection and compensatory land conservation for the construction of a transmission line in the state of Maine," DEP said in a May 11 statement.

Requirements include limits on transmission corridor width, forest preservation, culvert replacement and vegetation management projects, while broader grid programs like vehicle-to-grid integration enhance clean energy utilization across the region.

"In our original proposal we worked hard to develop a project that provided robust mitigation measures to protect the environment," NECEC Transmission CEO Thorn Dickinson said in a statement. "And through this permitting process, we now have made an exceedingly good project even better for Maine."

NECEC will be built on land owned or controlled by Central Maine Power. The 53 miles of new corridor on working forest land will use a new clearing technique for tapered vegetation, while the remainder of the project follows existing power lines.

Environmentalists said they agreed with the decision, and the mitigation measures state regulators took, noting similar momentum behind new wind investments in other parts of Canada.

"Building new ways to deliver low-carbon energy to our region is a critical piece of tackling the climate crisis," CLF Senior Attorney Phelps Turner said in a statement. "DEP was absolutely right to impose significant environmental conditions on this project and ensure that it does not harm critical wildlife areas."

Once complete, Turner said the transmission line will allow the region "to retire dirty fossil fuel plants in the coming years, which is a win for our health and our climate."

The Massachusetts Department of Public Utilities in June 2019 advanced the project by approving contracts for the state's utilities to purchase 9,554,940 MWh annually from Hydro-Quebec. Officials said the project is expected to provide approximately 2% to 4% savings on monthly energy bills.

Total net benefits to Massachusetts ratepayers over the 20-year contract, including both direct and indirect benefits, are expected to be approximately $4 billion, according to the state's estimates.

NECEC "will also deliver significant economic benefits to Maine and the region, including lower electricity prices, increased local real estate taxes and reduced energy costs with examples like battery-backed community microgrids demonstrating local resilience, expanded fiber optic cable for broadband service in Somerset and Franklin counties and funding of economic development for Western Maine," project developers said in a statement.​

Bruce Power Life-Extension Programme advances Ontario nuclear capacity through CANDU Major Component Replacement, reliable operation milestones, supply chain retooling for COVID-19 recovery, PPE production, ventilator projects, and medical isotope supply security.

Key Points

A program to refurbish CANDU reactors, extend asset life, and mobilize Ontario nuclear supply chain and isotopes.

✅ Extends CANDU units via Major Component Replacement

✅ Supports COVID-19 recovery with PPE and ventilator projects

✅ Boosts Ontario energy reliability and medical isotopes

Canada’s Bruce Power said on 1 May that unit 1 at the Bruce nuclear power plant had set a record of 624 consecutive days of reliable operation – the longest since it was returned to service in 2012.

It exceeded Bruce 8’s run of 623 consecutive days between May 2016 and February 2018. Bruce 1, a Candu reactor, was put into service in 1977. It was shut down and mothballed by the former Ontario Hydro in 1997, and was refurbished and returned to service in 2012 by Bruce Power.

Bruce units 3 and 4 were restarted in 2003 and 2004. They are part of Bruce Power’s Life-Extension Programme, and future planning such as Bruce C project exploration continues across the fleet, with units 3 and 4 to undergo Major Component Replacement (MCR) Projects from 2023-28, adding about 30 years of life to the reactors.

The refurbishment of Bruce 6 has begun and will be followed by MCR Unit 3 which is scheduled to begin in 2023. Nuclear power accounts for more than 60% of Ontario’s supply, with Bruce Power providing more than 30%   of the province’s electricity.

Set up of Covid recovery council
On 30 April, Bruce Power announced the establishment of the Bruce Power Retooling and Economic Recovery Council to leverage the province’s nuclear supply chain to support Ontario’s fight against Covid-19 and to help aid economic recovery.

Bruce Power’s life extension programme is Canada’s second largest infrastructure project and largest private sector infrastructure programme. It is creating 22,000 direct and indirect jobs, delivering economic benefits that are expected to contribute $4 billion to Ontario’s GDP and $8-$11 billion to Canada’s gross domestic product (GDP), Bruce Power said.

“With 90% of the investment in manufactured goods and services coming from 480 companies in Ontario and other provinces, including recent manufacturing contracts with key suppliers, we can harness these capabilities in the fight against Covid-19, and help drive our economic recovery,” the company said.

“An innovative and dynamic nuclear supply chain is more important than ever in meeting this new challenge while successfully implementing our mission of providing clean, reliable, flexible, low-cost nuclear energy and a global supply of medical isotopes,” said Bruce Power president and CEO Mike Rencheck. “We are mobilising a great team with our extended supply chain, which spans the province, to assist in the fight against Covid-19 and to help drive our economic recovery in the future.”

Greg Rickford, the Minister of Energy, Mines, Northern Development, and Minister of Indigenous Affairs, said the launch of the council is consistent with Ontario’s focus to fight Covid-19 as a top priority and a look ahead to economic recovery, and initiatives like Pickering life extensions supporting long-term system reliability.

The creation of the Council was announced during a live event on Bruce Power's Facebook page, in which Rencheck was joined by Associate Minister of Energy Bill Walker and Rocco Rossi, the president and CEO of the Ontario Chamber of Commerce.

Walker reiterated the Government of Ontario’s commitment to nuclear power over the long term and to the life extension programme, including the Pickering B refurbishment as part of this strategy.

The Council, which will be formed for the duration of the pandemic and will include of all of Bruce Power’s Ontario-based suppliers, will focus on the continued retooling of the supply chain to meet front-line Covid-19 needs to contribute to the province’s economy recovery in the short, medium and long term.

New uses for nuclear medical applications will be explored, including isotopes for the sterilisation of medical equipment and long-term supply security.

The supply chain will be leveraged to support the health care sector through the rapid production of medical Personal Protection Equipment for front line-workers and large-scale PPE donations to communities as well as participation in pilot projects to make ventilators within the Bruce Power supply chain or help identify technology to better utilise existing ventilators;

“Buy Local” tools and approaches will be emphasised to ensure small businesses are utilised fully in communities where nuclear suppliers are located.

The production of hand sanitiser and other cleaning products will be facilitated for distribution to communities.
