Existing technologies for direct air capture technologies require a lot of heat to remove CO2, once it has been absorbed in the filters. The process to date has been laborious and often very inefficient from an energy perspective. What was often missing in the process was a more efficient way to capture CO2 in the first place. The key to all of this is the filters, and it’s this aspect that more than one startup has been working on in recent years.
Israel-based RepAir Carbon has now come up with an approach inspired by the ideas behind fuel cell technology to do just that, and it has now closed a $ 1.5 million seed funding round co-led by Counteract and ESIL. , with the participation of Consensus Business Group, ImpactAssets and other investors. ESIL is a partnership between EDF Renouvelables, Johnson Matthey and Bazan Group.
RepAir Carbon’s objective is to develop this “cellular” approach for what it describes as “direct modular air capture” to capture or store greenhouse gases “on a gigaton scale”. The promise is much lower power consumption and a less CapEx-intensive modular design based on electrochemistry.
RepAir says it uses electric current and a selective membrane to separate CO2 from the air, consuming “up to 3 times less energy for every ton of CO2 captured without the need for high temperatures or pressure differences. important “.
Amir Shiner, Co-Founder and CEO of RepAir said: “Direct air capture plays a key role in any scenario where the global temperature rises by less than 2 ° C. However, today’s solutions are too expensive, energy intensive and resource intensive. We are working hard to develop technology with a responsible energy footprint that can be deployed in many other contexts. This investment will help us advance and optimize our TRL3 prototype.
Alongside Shiner, the RepAir team includes Co-Founder and Chairman Yehuda Borenstein, CTO Ben Achrai, PhD, and Board Member Yushan Yan, PhD.
Andrew Shebbeare, Managing Partner at Counteract, said: “We strongly believe in the role Direct Air Capture will play, but we also believe that today’s technology must evolve. With a promising platform and an exceptional team, we are confident that RepAir advances the state of the art and will help pave the way for a responsible and scalable DAC.
Eli Cymbalista, CEO of ESIL, said: “Our goal is to accelerate and commercialize start-ups with economically viable solutions that support the transition to a NetZero world. We believe RepAir fits exactly this specification and we are delighted to bring the skills and resources of our network of partners to help accelerate their progress.
In an interview with me, Shiner added, “We will eventually have more blocks that can evolve like Lego. We can evolve in a modular way. So we can put our device next to, say, a wind farm, where we get the energy to power the device. We are very flexible about the location of the device because we use air rather than the pollution emitted by a chimney.
