![]() ![]() ![]() But one thing is for sure - that there’s a growing list of entrepreneurs determined to get there.The fight against climate change is gaining momentum as more individuals and organizations recognize the urgent need to reduce carbon emissions. Last year, commercial carbon capture and storage facilities removed 40m tonnes of CO₂, just a fraction of the 10-15 gigatonnes that need to be removed per year to stay below the two degree mark by 2050. He adds that we need “all measures at hand” to remove CO₂ from the atmosphere whether it be point-source, DAC or new emerging technologies in the sector.Ĭurrently, not enough CO₂ is being removed from the atmosphere per year to reach net zero. Ryengen believes that more people are beginning to agree that carbon capture is “part of the solution,” to keeping the planet below the 2✬ mark by 2050, but says we must not forget that other solutions come hand in hand like wind and solar.Īt Carbon Clean, Sharma thinks the market will become more cost effective, especially given Europe’s rising ETS carbon market price. So where is the market heading in the next few years? “Our goal is to get all the way down to zero,” she adds. While ZEG Power is yet to commercialise its technology for use, Ryengen says that the startup plans to get its technology to capture between 90-100% of CO₂, aiming to produce just a kilo of CO₂ for each kilo of hydrogen produced. Hydrogen has a carbon footprint of 10kg CO₂ for every 1kg of hydrogen. Kathrine Ryengen, chief executive of ZEG Power. “The consequences of capturing CO₂ from the gas results in a higher yield of hydrogen, due to a chemical reaction between the water and the gas.” Kathrine Ryengen, CEO of ZEG Power, tells Sifted that the integration of carbon capture makes the hydrogen production process more efficient. This reaction generates heat, which is then fed back into the reactor to section off the captured carbon for storage. During this process, CO₂ is separated from hydrogen, which is then put in a fuel cell for energy use. Over in Norway, ZEG Power is capturing the carbon created as a byproduct of hydrogen production.įuel, gas and water is placed inside a reactor to create hydrogen. Emission-free energyįor some startups, however, carbon clean energy is their main gig. However, according to Laakso its fuel manufacturing service only accounts for 5% of its current customer value. This could help increase CO₂ yield, extend the product life cycle and reduce energy usage.Īs an additional revenue stream Soletair creates renewable energy by converting its captured CO₂ into hydrocarbons, a type of fuel. Also, Laakso says Soletair is working on several solutions, such as improving its sorbent - a material used to absorb liquid and gas - to capture CO₂. To tackle this, Solitair Power offers an “indoor air as a service” subscription model for €1 per person per day. And the cost of that energy is the big ‘elephant in the room’ for direct air capture, keeping the price of CO₂ per metric tonne at hundreds of dollars in some cases. In order to catch this amount of CO₂, the startup would need to use 10,500mWh of electricity. If we placed our systems around the city we could capture 222 tonnes in eight hours, and that’s just one city,” he says. “Helsinki’s metropolitan area has 8.75 square metres of office space. While it’s a considerably lower amount of CO₂ captured compared to startups like Carbon Clean, Laakso notes that if buildings used the technology on a large scale it could make a huge difference. Annually, that’s 20 tonnes of CO₂ captured per year, the same amount it would take 20 trees with a lifespan of 100 years each to capture. Laakso describes the business relationship with Wartsila as in “close cooperation”, helping the startup reach potential international clients.īut how much CO₂ can it grab? And how much energy does this require? “In an office of 2000m2, one ventilator captures 50kg of CO₂ per 8 hour day,” says Laakso. However, it is backed by 187-year-old ship engine and power plant maker Wartsila, which raised its $600k seed funding round in 2019. The startup sold its first commercial unit in February 2020 - although it won’t disclose who its customers are. ![]() Petri Laakso, chief executive of Soletair Power. ![]()
