Edda Aradottir is the chief executive of Carbfix, a company that captures CO2 byproduct from the largest geothermal plant in Iceland. Many Icelandic start-ups are tackling climate change.

File this one under Hope. And maybe book a trip to the innovation hub called Iceland.

Hannah Hall has a report at the Washington Post on Icelandic companies that are taking on global environmental challenges.

“The electric red and green glow of the production facility resembles the Icelandic aurora borealis. Algae in their growth stage flow through hundreds of glass tubes that travel from floor to ceiling, all part of a multistep process yielding nutrients for health supplements. Soon, all parts of each alga will be used.

“The facility, operated by Icelandic manufacturer Algalif, is a space of inspiration for Julie Encausse, a 34-year-old bioplastic entrepreneur. During a July summer storm, Svavar Halldorsson, an Algalif executive, was guiding her through a tour of the company’s newest facility on the Reykjanes Peninsula.

“By the end of 2023, this new facility aims to triple its production. After Algalif dries the microalgae and extracts oleoresin, a third of this output then goes toward health supplements. Algalif has traditionally used the rest as a fertilizer. Now Encausse, founder and chief executive of the bioplastic start-up Marea, hopes to use that leftover biomass to create a microalgae spray that can reduce the world’s reliance on plastic packaging.

“Her newest partnership with Algalif is part of a start-up network in Iceland that focuses on inventive and creative technologies to address the climate and sustainability crisis. The Sjavarklasinn (‘Iceland Ocean Cluster’) network includes environmental entrepreneurs working across several industries.

“Thor Sigfusson founded the network in 2012 after conducting research on how partnerships between companies in Iceland’s technology sector helped expand that industry. At the time, he found that the fishing industry was not experiencing the same collaboration or growth.

“ ‘Even though companies were in the same building together, fishing from the same quotas and facing similar challenges, they were closed off,’ said Alexandra Leeper, the Iceland Ocean Cluster’s head of research and innovation.

“Three cod hanging on the wall of the second-floor entryway are the first thing to greet any visitor to the Iceland Ocean Cluster. Lightbulbs shine from their centers, and the dried scales filter the light to fill the space with an amber glow. The precise design is one that underlines the group’s belief that using 100 percent of a fish or natural resource can give rise to innovative technologies. …

“Encausse and Marea co-founder Edda Bjork Bolladottir have partnered with the cluster for 2½ years. Encausse says that involvement was core to their company’s inception.

“ ‘There is a collaborative mind-set when being on an island,’ she said. ‘We need to work together to survive, and this was passed from generation to generation.’

“In a country about the size of Kentucky, the people of Iceland have had to learn how to guard their resources. Encausse has discovered that often means using 100 percent of any material — a lesson she’s now implementing in her work with Algalif. She created a food coating from Algalif’s leftover biomass, a product she’s named Iceborea — in a nod to theaurora borealis.

“ ‘We are repurposing it and making something with value that gives it another life to avoid using more plastic,’ Encausse said. Once Algalif’s factory expands over the next year, it will have 66 tons of microalgae leftovers that Encausse’s company can tap each year.

“When sprayed onto fresh produce, Iceborea becomes a natural thin film and a semipermeable barrier that can protect against microorganisms. Iceborea can either be eaten with produce or washed off, reducing the need for plastic packaging.

“[Edda Aradottir] is the chief executive of Carbfix, a company capturing CO2 byproduct from the largest geothermal plant in Iceland, Hellisheidi, and injecting it into stone to be buried underground.

“Carbfix’s successful trials have marked a global milestone for carbon sequestration. It also has received international recognition — and Aradottir’s leadership has already served as a model for growing start-ups and other founders in the cluster trying to tackle extensive environmental concerns. …

“Another Icelandic company, GeoSilica, harvests silica buildup from the Hellisheidi waste stream to make health supplements.GeoSilica reaches the Icelandic and European markets, and its chief executive, Fida Abu Libdeh, is also working with the Philippines to pilot her silica-removal technology to create similar sustainable factory processes.

“A Palestinian from Jerusalem, Abu Libdeh moved to Iceland in 1995 at age 16, a transition she described as difficult because of the language barrier and the country’s small immigrant population. In 2012, she graduated from the University of Iceland after studying sustainable energy engineering and researching the health benefits of silica. That same year, she and Burkni Palsson co-founded GeoSilica.

“Ever since moving to Iceland, she was impressed with how the country produced electricity through geothermal sources. …

“GeoSilica is not formally part of the Iceland Ocean Cluster, but the network it has fostered reflects the same collaborative approach. Abu Libdeh has worked with cluster companies and held investor meetings at its headquarters. It’s a place that founders want to be, she said, where they want to learn from each other even if they are competitors in their fields.

“While there has been progress over the years, Abu Libdeh said, it’s still a challenge for women to enter this entrepreneurial space. In 2020, less than 1 percent of investment went to women-founded start-ups, according to a recent European Women in Venture Capital report. …

“What began as a dozen start-ups in 2012 has now grown to more than 70 members and associated firms connected to the Iceland Ocean Cluster. … There are now four sister clusters in the United States, as well as one in Denmark and one in the Faroe Islands.

“The Alaska Ocean Cluster, which was the first to follow the Icelandic model, has already accelerated policy change in the United States. Sen. Lisa Murkowski (R-Alaska) proposed legislation last year to create ‘Ocean Innovation Clusters in major U.S. port cities, which would provide grants along the U.S. coastline and the Great Lakes.

“ ‘I’ve learned a great deal from our friends in Iceland who created a roadmap of innovation and public/private partnership when they established the first Oceans Cluster in Reykjavik,’ Murkowski said in an email.”

Fairwater, developed by Frasers Property, is the largest geothermal community in the southern hemisphere.

These days there’s a lot of talk about “sustainable” daily-living practices and “sustainable” business practices. But let’s be honest: some practices are more sustainable than others.

One monitoring organization that sets a high bar is the Green Building Council of Australia (GBCA).

Clarissa Sebag-Montefiore wrote recently at the Guardian about projects the council has approved: “In 2016, a new master-planned estate in [Blacktown, near Sydney] became the first residential community in New South Wales to be awarded a top, six-star Green Star community rating by the Green Building Council of Australia.

“Not only that, Fairwater, developed by Frasers Property, is the largest geothermal community in the southern hemisphere. Houses are cooled or heated by a refrigerant that pumps air underground then back to the surface, using less power than air-conditioning or heating and saving residents of a three-bedroom house $500 to $600 a year.

“ ‘There’s this avenue of mature trees with this massive lake and lovely terrace houses – yoga by the lake, cycling paths, all these people walking,’ says the GBCA chief executive, Romilly Madew. …

“Green-star buildings produce, on average, 62% fewer greenhouse gas emissions and use 51% less potable water and 66% less electricity than average buildings in Australia, according to GBCA’s 2013 report The Value of the Green Star.

“Since launching in 2003, hundreds of buildings around the country have been certified for the rating system and 120,000 people are now moving into Green Star communities. …

“The key is looking at the project holistically, says Madew. ‘It’s about going back to that old adage of community: people, walkability, liveability, places for the kids to play. [We want to] change the way people think about how they live.’

“Developers, ultimately, ‘are there to sell house and land packages – so they’re not going to be successful unless they’re building something people want to buy. Take “sustainability” out and ask what [buyers] want. They want something close to amenities – schools, public transport, shops and parks. And a home that is cheap to run.’ ” Read about other sustainable projects in Australia here.

In September, Victoria Lynden tweeted about Costa Rica’s clean electricity. Although hydroelectric and geothermal approaches sometimes have issues of their own and cars in Costa Rica still use gas, two months without using fossil fuels to generate electricity sounded pretty good to me.

Brad Plumer wrote at Vox, “Costa Rica is pulling off a feat most countries just daydream about: For two straight months, the Central American country hasn’t burned any fossil fuels to generate electricity. That’s right: 100 percent renewable power.

“This isn’t a blip, either. For 300 total days last year and 150 days so far [in 2016], Costa Rica’s electricity has come entirely from renewable sources, mostly hydropower and geothermal. Heavy rains have helped four big hydroelectric dams run above their usual capacity, letting the country turn off its diesel generators.

“Now, there’s a huge, huge caveat here: Costa Rica hasn’t eschewed all fossil fuels entirely. The country still has more than 1 million cars running on old-fashioned gasoline, which is why imported oil still supplies over half its total energy needs. The country also has cement plants that burn coal.

“What Costa Rica’s doing is nevertheless impressive — and a reflection of how serious the tiny Central American country is about going green. At the same time, a closer look at the story shows just how difficult it would be for other countries to pull off something similar.

“When many people think of ‘renewables,’ they tend to think of giant wind turbines or gleaming solar panels. But that’s not what Costa Rica is relying on. For years, roughly 80 percent of the nation’s electricity has come from a technology that’s more than a century old — hydroelectric dams …

“Another 12 percent or so of Costa Rica’s electricity comes from geothermal plants, which tap heat deep in the Earth’s crust and can also run around the clock. …

“So if Costa Rica can get 100 percent of its electricity from renewable sources, why couldn’t other countries do the same? Why can’t the United States, which is far richer?

“One obstacle here is that hydropower and geothermal are very location-specific — and only a few countries are lucky enough to have such rich resources. Iceland gets nearly 100 percent of its electricity from these two sources. Paraguay gets almost all of its electricity from the massive Itaipú Dam. Brazil gets more than 75 percent of its power from hydropower. But those are exceptions. For most countries, hydropower can only satisfy a portion of their power needs.” Read on.

Seems to me that when a country wants to be greener (whether for the environment or to save money or both), it has already taken the first step to finding solutions that work for its own geography.
