More than half of new U.S. electric-generating capacity in 2023 will be solar

Space-Based Solar Power enables wireless energy transfer from orbital solar arrays, using microwave beaming to rectennas on Earth, delivering clean baseload power beyond weather and night limits, as demonstrated by Caltech and NASA.

Key Points

Space-based solar power beams microwaves from arrays to rectennas, delivering clean electricity beyond weather and night.

✅ Caltech demo proved wireless power transfer in space.

✅ Microwaves beam to rectennas for grid-scale clean energy.

✅ Operates above clouds, enabling continuous baseload supply.

Ali Hajimiri thinks there’s a better way to power the planet — one that’s not getting the attention it deserves. The Caltech professor of electrical engineering envisages thousands of solar panels floating in space, unobstructed by clouds and unhindered by day-night cycles, effectively generating electricity from the night sky for continuous delivery, wirelessly transmitting massive amounts of energy to receivers on Earth.

This year, that vision moved closer to reality when Mr. Hajimiri, together with a team of Caltech researchers, proved that wireless power transfer in space was possible: Solar panels they had attached to a Caltech prototype in space successfully converted electricity into microwaves and beamed those microwaves to receivers, as a demonstration of beaming power from space to devices about a foot away, lighting up two LEDs.

The prototype also beamed a tiny but detectable amount of energy to a receiver on top of their lab’s building in Pasadena, Calif. The demonstration marks a first step in the wireless transfer of usable power from space to Earth, and advances in low-cost solar batteries could help store and smooth that power flow — a power source that Mr. Hajimiri believes will be safer than direct sun rays. “The beam intensity is to be kept less than solar intensity on earth,” he said.

Finding alternative energy sources is one of the topics that will be discussed by leaders in business, science and public policy, including wave energy, during The New York Times Climate Forward event on Thursday. The Caltech demonstration was a significant moment in the quest to realize space-based solar power, amid policy moves such as a proposed tenfold increase in U.S. solar that would remake the U.S. electricity system — a clean energy technology that has long been overshadowed by other long-shot clean energy ideas, such as nuclear fusion and low-cost clean hydrogen.

If space-based solar can be made to work on a commercial scale, said Nikolai Joseph, a NASA Goddard Space Flight Center senior technology analyst, and integrate with peer-to-peer energy sharing networks, such stations could contribute as much as 10 percent of global power by 2050.

The idea of space-based solar energy has been around since at least 1941, when the science-fiction writer Isaac Asimov set one of his short stories, “Reason,” on a solar station that beamed energy by microwaves to Earth and other planets.

In the 1970s, when a fivefold increase in oil prices sparked interest in alternative energy, NASA and the Department of Energy conducted the first significant study on the topic. In 1995, under the direction of the physicist John C. Mankins, NASA took another look and concluded that investments in space-launch technology were needed to lower the cost and move closer to cheap abundant electricity before space-based solar power could be realized.

“There was never any doubt about it being technically feasible,” said Mr. Mankins, now president of Artemis Innovation Management Solutions, a technology consulting group. “The cost was too prohibitive.”

Bimbo Canada VPPAs secure renewable electricity from RES wind and solar projects in Alberta, totaling 170MW, via 15-year contracts to offset consumption, advance RE100 goals, and drive decarbonization across bakeries, depots, and distribution centers.

Key Points

Virtual power purchase agreements sourcing wind and solar to offset Bimbo Canadas electricity and support RE100.

✅ 15-year RES contracts for Alberta wind and solar capacity

✅ Offsets electricity for bakeries, depots, and distribution centers

✅ Advances Grupo Bimbo RE100 target for 100% renewable power

Canada's oldest and largest bakery, Bimbo Canada, has signed two virtual power purchase agreements (VPPAs) with Renewable Energy Systems  (RES) to procure renewable electricity, similar to federal green electricity contracts advancing in Alberta, that will offset 100 per cent of the company's electricity consumption in Canada. The projects are expected to be fully operational by December, 2022.

Canada is the second market, alongside the United States, to enter into VPPAs, where companies like Amazon clean energy projects are expanding rapidly. These agreements, together with additional sustainability initiatives conducted around the world by the parent company Grupo Bimbo, will help the company offset 90 per cent of its global electricity consumption.

"Bimbo Canada is committed to nourishing a better world through productive sustainability practices," said Joe McCarthy, president of Bimbo Canada. "These agreements are the next big step in reducing our environmental footprint, as peers such as Arvato's first solar plant signal industry momentum, and becoming leaders in responsible stewardship of the environment."

The 15-year agreements with RES will support the commercial development of two renewable energy projects in southern Alberta, consisting of wind and solar projects, similar to RBC's solar PPA announced in the region, totaling 170MW of installed capacity. Under these two agreements, Bimbo Canada will procure the benefit of approximately 50MW of renewable electricity to offset electricity consumption for its 16 bakeries, 14 distribution centres and 191 depots. Commercial development for the wind and solar farms will be finalized later this year by RES Canada and the projects are expected to be fully operational by the end of next year.  

"RES is proud that its Alberta wind and solar projects, amid growth such as a $200M Alberta wind farm led by a Buffett-linked firm, are helping Bimbo Canada meet its sustainability initiatives," said Peter Clibbon, RES Senior VP of Development. "It's a win-win situation with our projects delivering competitive wind and solar electricity to Bimbo Canada, and while providing our host communities with long-term tax and landowner income."

In 2018, Grupo Bimbo joined RE100, a global initiative led by The Climate Group and in partnership with Carbon Disclosure Project (CDP) and committed to operating with 100 per cent renewable electricity by 2025. As a leading supplier of fresh-baked goods and snacks for Canadian families, these agreements support the company's targets and builds upon many successful past sustainability initiatives, as market activity by Canadian Solar project sales continues nationwide.

"The renewable electricity initiatives in our operations respond to Grupo Bimbo's deep commitment that we have had for many decades globally with the planet and with present and future generations," said Daniel Servitje, global CEO of Grupo Bimbo. "With this announcement, we have achieved another important milestone for the company on our journey towards becoming 100 per cent renewable electricity by 2025."

Last year, Bimbo Canada reduced product waste and exceeded its product waste reduction target by 18 per cent, which saved four million units of products from landfills. The company also eliminated 174 metric tonnes of plastic per year (equal to 43 adult elephants) through several packaging optimization initiatives.

Earlier this year, Bimbo Canada signed the Canada Plastics Pact (CPP) and, amid a broader push for clean energy exemplified by Edmonton rooftop solar installations, earned its first ENERGY STAR certification for its Hamilton, Ontario bakery. The company will continue to work towards other initiatives that fulfill its commitment to be a sustainable, highly productive and deeply humane company.

Condo EV charging retrofits face strata approval thresholds, installation costs, and limited electrical capacity, but government rebates, subsidies, and smart billing systems can improve ROI, property value, and feasibility amid electrician shortages and infrastructure constraints.

Key Points

Condo EV charging retrofits equip multiunit parking with EV chargers, balancing costs, bylaws, capacity, and rebates.

✅ Requires owner approval (e.g., 75% in B.C.) and clear bylaws

✅ Leverage rebates, subsidies, and load management to cut costs

✅ Plan billing, capacity, and phased installation to increase ROI

Retrofitting an existing multiunit residential building with electric vehicle charging stations is a complex and costly exercise, as high-rise EV charging challenges in MURBs demonstrate, even after subsidies, but the biggest hurdle to adoption may be getting enough condo owners on board.

British Columbia, for example, offers a range of provincial government subsidies to help condo corporations (referred to in B.C. as stratas) with everything from the initial research to installing the chargers. But according to provincial strata law, three-quarters of owners must support the plan before it is implemented, though new strata EV legislation could make approvals easier in some jurisdictions.

“The largest challenge is getting that 75-per-cent majority approval to go ahead,” says EV charging specialist Patrick Breuer with ChargeFwd Ltd., a Vancouver-based sustainable transport consultancy.

Chris Brunner, a strata president in Vancouver, recently upgraded all the building’s parking stalls for EV charging. His biggest challenge was getting the strata’s investment owners, who don’t live in the building and were not interested in spending money, to support the project.

“We had to sell it in two ways,” Mr. Brunner says. “First, that there’s going to be a return on investment, including vehicle-to-building benefits that support savings and grid stability, and second, that there will come a time when this will be required. And if we do it now, taking advantage of the generous rebates and avoiding price increases for expertise and materials, we’ll be ahead of the curve.”

Once the owners have voted in favour, the condo board can begin the planning process and start looking for rebates. The B.C. government will provide a rebate of up to 75 per cent for the consulting phase, with additional provincial rebates available through current programs. It’s referred to as an “EV Ready” plan, which is a professionally prepared document that describes how to implement EV charging fairly, and estimates its cost.

Once a condo has completed the EV Ready plan, it becomes eligible for other rebates, such as the EV Ready Infrastructure subsidy, which will bring power to each individual parking stall through an energized outlet. This is rebated at 50 per cent of expenses, up to $600 a stall.

There are further rebates of up to 75 per cent for installing the charging stations themselves, and B.C. charging rebates extend to home and workplace programs, too. The program is administered by BC Hydro, a Crown corporation that receives funding in annual increments. “Right now, it’s funded until March 31, 2023,” Mr. Breuer says.

“Realtors are valuing [individual charging stations] from $2,000 to $10,000,” he said. The demand for installing EV chargers in buildings has grown to such an extent that it’s hard to find qualified electricians, Mr. Breuer says.

However, even with subsidies, there are some buildings where it doesn’t make financial sense to retrofit them. “If you have to core through thin floors or there’s a big parkade with a large voltage drop, it isn’t financially viable,” Mr. Breuer says. “We do a lot of EV Ready plans, but not all the projects can go ahead.”

For many people, it’s resistance to the unknown that is preventing them from voting for the retrofit, according to Carter Li of Toronto-based Swtch Energy Inc., which provides charging in high-density urban settings. It has done retrofits on 200 multiunit residential buildings in the Toronto area, and Calgary condo charging efforts show similar momentum in other cities, too. “They’re worried about paying for someone else’s electricity,” he says. Selling owners on the idea requires educating them about how the billing will work, maximizing electrical capacity to keep costs down, using government subsidies and the anticipated boost in property value.

Ontario currently does not provide any subsidies for retrofitting condos for EV charging. However, there is a stipulation under the Condominium Act that if owners request EV charging be installed and provide a condo board with sufficient documentation, an assessment will be conducted.

When Jeremy Benning was on the board of his Toronto condo in 2018, a few residents inquired about installing EV charging. A committee of owners did the legwork, and found a company that could do the infrastructure installation as well as set up accounts for individual billing purposes. Residents were surveyed a number of times before going ahead with the installation.

Mr. Benning estimates it cost about $40,000 to install two electrical subpanels to accommodate EV chargers in 20 parking spaces. Although the condo corporation paid the money up front out of its operating budget, everyone who ordered a charger will pay back their share over time. Many who do not even own an EV have opted to add a valuable frill to their unit.

The board considered applying for a subsidy from Natural Resources Canada, but it would require a public charger in the visitor parking lot. “The rebate wasn’t enough to pay for the cost of putting in that charging station,” Mr. Benning says. “Also, you have to maintain it, and what if it gets vandalized? It wasn’t worth it.”

Quebec’s Roulez Vert (Ride Green) program offers extensive provincial rebates and incentives for retrofitting condo buildings. If a single condo owner wants to install an EV charger, the government will refund up to 50 per cent of the installation cost or up to $5,000, whichever is less.

Otherwise, a property manager can qualify for a maximum of $25,000 a year to retrofit a building and can sometimes complete the work in stages. “They may do the first installation in one year, and then continue the next year,” says Léo Viger-Bernard of Recharge Véhicule Électrique (RVE). Recently, the Quebec government confirmed this program will run until 2027.

RVE consults with condo corporations, operates an online platform (murby.com) with resources for building owners, and sells a demand charge controller (DCC), which is an electric vehicle energy management system. The DCC allows an electrician to plug the EV charger directly into the electrical infrastructure of a single condo or apartment unit. Not only does this reduce extra wiring, but it also monitors the electrical consumption in each unit, only powering the charging station when there’s available electricity. Billing is assigned to the actual unit’s electricity bill.

Currently there are about 12,000 DCC units installed in retrofitted buildings across Canada, some that are 40 or 50 years old. “It’s not a question of age; it’s more the location of the electric meters,” Mr. Viger-Bernard says. The DCC can be installed either on the roof or on different floors.

According to Michael Wilk, president of Montreal-based Wilkar Property Management Inc., the biggest barrier is getting condo owners to understand the necessity of doing a retrofit now, as opposed to waiting. He uses price increases to try to convince them.

“Right now, the cost of doing a retrofit is 35 per cent more than it was two years ago,” he says. “If you wait another two years, we can only anticipate it’s going to be 35 per cent higher because of the rising cost of labour, parts and equipment.”

In Nova Scotia, Marc MacDonald of Spark Power Corp. installed an EV charger with a DCC unit at a condo near Halifax about a year ago. “They only had space in their electrical room to add a device for up to 10 EV chargers,” he says. The condo board was hesitant, demanding a great deal of information. “They were concerned about everyone wanting an EV charger.”

Now that Nova Scotia has introduced a program for rebates and incentives to install EV chargers in condos, on-street sites and more, Mr. MacDonald anticipates demand will increase, though Atlantic EV adoption still lags the national average. “But they’ll have to settle with reality. Not everyone can have an EV charger if the building can’t accommodate it.”

Microgrid solar outage algorithms optimize renewable energy during blackouts using grid-forming inverters, islanding control, demand forecasting, and energy storage from batteries and EVs, improving reliability by up to 35% for resilient power sharing.

Key Points

Algorithms that island homes, forecast demand, and prioritize critical loads using storage and grid-forming inverters.

✅ Disconnects inverters to form resilient neighborhood microgrids

✅ Forecasts solar, wind, and demand; allocates energy fairly

✅ Uses EVs and batteries; boosts reliability by up to 35%

Some people who have solar panels on their roof are under the impression that they can use them to power their home in the case of an outage, but that simply is not the case. Homes do remain connected to the grid during outages, as U.S. power outage risks grow, but the devices tasked with managing solar panels are normally turned off due to safety concerns. This permanent grid connection essentially prevents homeowners from drawing on the power that their own renewable energy resources generate.

This could be about to change, however, thanks to the efforts of a team of University of California San Diego engineers who have come up with algorithms that would enable homes to share and use their power in outages by disconnecting solar inverters from the grid. Their algorithms work with the existing technology and would have the added benefit of boosting the system’s reliability by as much as 35 percent.

The genius of their work lies in the ability of the algorithm to prioritize the distribution of power from the renewable resources in outages. Their equation considers forecasts for wind and solar power generation to address clean energy intermittency challenges and the available energy storage, including batteries and electric vehicles. It combines this information with the projected energy usage of residents and the amount of energy the homes are able to produce. It can be programmed to prioritize in several different ways, the most vital of which is by favoring those who need power urgently, such as those using life support equipment. It could also prioritize those who are willing to pay extra or reward those who typically generate an energy surplus during normal operations.

Learning lessons from past outages

Lead author Abdulelah H. Habib said the engineers were inspired to find a way to use the renewable power in outages by the events of Hurricane Sandy. This storm affected more than eight million people on the nation’s East Coast, some of whom were left without power for as long as two weeks.

According to the researchers, most customers prefer sharing community-scale storage systems over having systems in each home because of the lower costs. One of the paper’s senior authors, Raymond de Callafon, said that homes that are connected together are not only more resilient in power outages but they also happen to be more resilient to price fluctuations.

Each home needs to be equipped with special circuit breakers that can be remotely controlled, while utilities would need to install some communications methods so the power systems within a particular residential cluster can communicate amongst themselves. They also need a “grid forming inverter” to help them connect to one another and manage excess solar on networks safely.

One stumbling block that will have to be overcome is the current regulations. Most states do not allow individual homeowners to sell power to other homeowners, so there would have to be some adjustments to make this a reality.

Solar power growing in popularity

Solar power’s popularity is currently on the rise, and reductions in cost as the technology improves are only expected to drive this growth even further. REC CEO Steve O’Neil told CNBC that the installation rates of solar double every two years, a trend that informs residential solar economics for homeowners even though just two percent of the planet’s electricity comes from converting sunlight to energy. This means there is plenty of room for expansion. The world’s current solar capacity is 305 gigawatts, compared to just 50 gigawatts in 2010.

In addition, he pointed out that the price of solar energy has dropped by 70 percent since the year 2010 and continues to fall; it costs around eight cents per kilowatt hour at the moment. Another factor that could boost adoption is storage improvements, driven by affordable solar batteries that expand capacity, which will allow solar energy to be used even on overcast days.

Volvo Electric Heavy-Duty Trucks lead Europe’s e-mobility shift, meeting strict emissions rules with battery-electric drivelines, hydrogen fuel cell roadmaps, fast charging infrastructure, and autonomous freight solutions for regional haulage and urban construction.

Key Points

A battery-electric heavy truck range for haulage and urban construction, targeting zero emissions and compliance.

✅ Up to 44t GCW, ranges up to 300 km per charge

✅ Battery-electric now; hydrogen fuel cells targeted next

✅ Production from 2022; suited to haulage and construction

According to the report published by Allied Market Research, the global electric truck market generated $422.5M (approx €355.1M) in 2019 and is estimated to reach $1.89B (approx €1.58B) by 2027, registering a CAGR of 25.8% from 2020 to 2027, reflecting broader expectations that EV adoption within a decade will accelerate worldwide. 

The surge in government initiatives to promote e-mobility and stringent emission norms on vehicles using fossil fuels (petrol and diesel) is driving the growth of the global electric truck market, while shifts in the EV aftermarket are expected to reinforce this trend. 

Launching a range of electric trucks in 2021
Volvo is among the several companies, including early moves like Tesla's truck reveal efforts, trying to cash in on this popular and lucrative market. Recently, the company announced that it’s going to launch a complete heavy-duty range of trucks with electric drivelines starting in Europe in 2021. Next year, hauliers in Europe will be able to order all-electric versions of Volvo’s heavy-duty trucks. The sales will begin next year and volume production will start in 2022. 

“To reduce the impact of transport on the climate, we need to make a swift transition from fossil fuels to alternatives such as electricity. But the conditions for making this shift, and consequently the pace of the transition, vary dramatically across different hauliers and markets, depending on many variables such as financial incentives, access to charging infrastructure and type of transport operations,” explains Roger Alm, President Volvo Trucks.

Used for regional transport and urban construction operations
According to the company, it is now testing electric heavy-duty models – Volvo FH, FM, and FMX trucks, which will be used for regional transport and urban construction operations in Europe, and in the U.S., 70 Volvo VNR Electric trucks are being deployed in California initiatives as well. These Volvo trucks will offer a complete heavy-duty range with electric drivelines. These trucks will have a gross combination weight of up to 44 tonnes.

“Our chassis is designed to be independent of the driveline used. Our customers can choose to buy several Volvo trucks of the same model, with the only difference being that some are electric and others are powered by gas or diesel. As regards product characteristics, such as the driver’s environment, reliability, and safety, all our vehicles meet the same high standards. Drivers should feel familiar with their vehicles and be able to operate them safely and efficiently regardless of the fuel used,” says Alm.

Fossil free by 2040
Depending on the battery configuration the range could be up to 300 km, claims the company. Back in 2019, Volvo started manufacturing the Volvo FL Electric and FE Electric for city distribution and refuse operations, primarily in Europe, while in the van segment, Ford's all-electric Transit targets similar urban use cases. Volvo Trucks aims to start selling electric trucks powered by hydrogen fuel cells in the second half of this decade. Volvo Trucks’ objective is for its entire product range to be fossil-free by 2040.

Back in 2019, Swedish autonomous and electric freight mobility leader provider Einride’s Pod became the world’s first autonomous, all-electric truck to operate a commercial flow for DB Schenker with a permit on the public road. Last month, the company launched its next-generation Pod in the hopes to have it on the road starting from 2021, while major fleet commitments such as UPS's Tesla Semi pre-orders signal broader demand.

Faroe Islands Tidal Kites harness predictable ocean energy with underwater turbines by Minesto, flying figure-eight paths in fjords to amplify tidal power and deliver renewable electricity to SEV's grid near Vestmanna at megawatt scale.

Key Points

Subsea turbines that fly figure-eight paths to harvest tidal currents, delivering reliable renewable power to the grid.

✅ Figure-eight control amplifies speed vs. ambient current

✅ Predictable baseload complementing wind and hydro

✅ 1.2 MW Dragon-class units planned for Faroese fjords

Known as "sea dragons" or "tidal kites", they look like aircraft, but these are in fact high-tech tidal turbines, part of broader ocean and river power efforts generating electricity from the power of the ocean.

The two kites - with a five-metre (16ft) wingspan - move underwater in a figure-of-eight pattern, absorbing energy from the running tide. They are tethered to the fjord seabed by 40-metre metal cables.

Their movement is generated by the lift exerted by the water flow - just as a plane flies by the force of air flowing over its wings.

Other forms of tidal power use technology similar to terrestrial wind turbines, and emerging kite-based wind power shows the concept's versatility, but the kites are something different.

The moving "flight path" allows the kite to sweep a larger area at a speed several times greater than that of the underwater current. This, in turn, enables the machines to amplify the amount of energy generated by the water alone.

An on-board computer steers the kite into the prevailing current, then idles it at slack tide, maintaining a constant depth in the water column. If there were several kites working at once, the machines would be spaced far enough apart to avoid collisions.

The electricity is sent via the tethering cables to others on the seabed, and then to an onshore control station near the coastal town of Vestmanna.

The technology has been developed by Swedish engineering firm Minesto, founded back in 2007 as a spin-off from the country's plane manufacturer, Saab.

The two kites in the Faroe Islands have been contributing energy to Faroe's electricity company SEV, and the islands' national grid, on an experimental basis over the past year.

Each kite can produce enough electricity to power approximately 50 to 70 homes.

But according to Minesto chief executive, Martin Edlund, larger-scale beasts will enter the fjord in 2022.

"The new kites will have a 12-metre wingspan, and can each generate 1.2 megawatts of power [a megawatt is 1,000 kilowatts]," he says. "We believe an array of these Dragon-class kites will produce enough electricity to power half of the households in the Faroes."

The 17 inhabited Faroe islands are an autonomous territory of Denmark. Located halfway between Shetland and Iceland, in a region where U.K. wind lessons resonate, they are home to just over 50,000 people.

Known for their high winds, persistent rainfall and rough seas, the islands have never been an easy place to live. Fishing is the primary industry, accounting for more than 90% of all exports.

The hope for the underwater kites is that they will help the Faroe Islands achieve its target of net-zero emission energy generation by 2030, with advances in wave energy complementing tidal resources along the way.

While hydro-electric power currently contributes around 40% of the islands' energy needs, wind power contributes around 12% and fossil fuels - in the form of diesel imported by sea - still account for almost half.

Mr Edlund says that the kites will be a particularly useful back-up when the weather is calm. "We had an unusual summer in 2021 in Faroes, with about two months with virtually no wind," he says.

"In an island location there is no possibility of bringing in power connections from another country, and tidal energy for remote communities can help, when supplies run low. The tidal motion is almost perpetual, and we see it as a crucial addition to the net zero goals of the next decade."

Minesto has also been testing its kites in Northern Ireland and Wales, where offshore wind in the UK is powering rapid growth, and it plans to install a farm off the coast of Anglesey, plus projects in Taiwan and Florida.

The Faroe Islands' drive towards more environmental sustainability extends to its wider business community, with surging offshore wind investment providing global momentum. The locals have formed a new umbrella organisation - Burðardygt Vinnulív (Faroese Business Sustainability Initiative).

It currently has 12 high-profile members - key players in local business sectors such as hotels, energy, salmon farming, banking and shipping.

The initiative's chief executive - Ana Holden-Peters - believes the strong tradition of working collaboratively in the islands has spurred on the process. "These businesses have committed to sustainability goals which will be independently assessed," she says.

"Our members are asking how they can make a positive contribution to the national effort. When people here take on a new idea, the small scale of our society means it can progress very rapidly."

One of the islands' main salmon exporters - Hiddenfjord - is also doing its bit, by ceasing the air freighting of its fresh fish. Thought to be a global first for the Atlantic salmon industry, it is now exporting solely via sea cargo instead.

According to the firm's managing director Atli Gregersen this will reduce its transportation CO2 emissions by more than 90%. However it is a bold move commercially as it means that its salmon now takes much longer to get to key markets.

For example, using air freight, it could get its salmon to New York City within two days, but it now takes more than a week by sea.

What has made this possible is better chilling technology that keeps the fresh fish constantly very cold, but without the damaging impact of deep freezing it. So the fish is kept at -3C, rather than the -18C or below of typical commercial frozen food transportation.

"It's taken years to perfect a system that maintains premium quality salmon transported for sea freight rather than plane," says Mr Gregersen. "And that includes stress-free harvesting, as well as an unbroken cold-chain that is closely monitored for longer shelf life.

"We hope, having shown it can be done, that other producers will follow our lead - and accept the idea that salmon were never meant to fly."

Back in the Faroe Island's fjords, a firm called Ocean Rainforest is farming seaweed.

The crop is already used for human food, added to cosmetics, and vitamin supplements, but the firm's managing director Olavur Gregersen is especially keen on the potential of fermented seaweed being used as an additive to cattle feed.

He points to research which appears to show that if cows are given seaweed to eat it reduces the amount of methane gas that they exhale.

"A single cow will burp between 200 and 500 litres of methane every day, as it digests," says Mr Gregersen. "For a dairy cow that's three tonnes per animal per year.

"But we have scientific evidence to show that the antioxidants and tannins in seaweed can significantly reduce the development of methane in the animal's stomach. A seaweed farm covering just 10% of the largest planned North Sea wind farm could reduce the methane emissions from Danish dairy cattle by 50%."

The technology that Ocean Rainforest uses to farm its four different species of seaweed is relatively simple. Tiny algal seedlings are affixed to a rope which dangles in the water, and they grow rapidly. The line is lifted using a winch and the seaweed strands simply cut off with a knife. The line goes back into the water, and the seaweed starts growing again.

Currently, Ocean Rainforest is harvesting around 200 tonnes of seaweed per annum in the Faroe Islands, but plans to scale this up to 8,000 tonnes by 2025. Production may also be expanded to other areas in Europe and North America.
