Airthium, with a valuation of $55 million, is raising funds on Wefunder. The company has designed a long-duration battery that is cheaper than gas, coal, and nuclear. The battery of Airthium can store 100 times more energy at the same cost as it is powered by sun and wind. Airthium is now building a heat engine that can dramatically cut carbon dioxide emissions and pollution. Andrei Klochko and Franck Lahaye founded Airthium in 2017. The current crowdfunding campaign has a minimum target of $50,000 and a maximum target of $5,000,000. The campaign proceeds will be used for payroll, contractors, equipment, lab and office space, and administrative expenses.

Climate change is both one of the biggest threats humanity has ever faced and the biggest business opportunity of the century. The rapid pace of climate change endangers our ability to adapt to our changing environment. Its ultimate severity will depend on our ability to quickly reduce greenhouse gas emissions. 

Airthium is developing a heat pump and energy storage solution that could be transformative in the fight against climate change.

Founder Profile

Airthium Founder Andrei Klochko on Replacing Fossil Fuel

Industrial buildings venting sky-high plumes of smoke are the epitome of air pollution. Many of them still rely on fossil fuels, one of the greatest culprits of climate change. But like Hawaii, which recently shut down its last coal-fired power plant, some want to change for the greener.

Airthium is assisting with a low-cost, zero-emission heat pump for industrial use and electric power generation. The company also plans to use its heat pump for long-term energy storage, making renewable energy a more viable power option. We reached out to co-founder and CEO Andrei Klochko to learn how Airthium's solution can compete against fossil fuel prices and help prevent carbon emissions.
