SkyDeck features College startups

UC Berkeley is not just one of the best research universities in the world, but also a unique place for entrepreneurs, students and alumni to grow and build their own innovative startups. Many of the ideas are based on issues young entrepreneurs first encountered in Berkeley classes or labs. Two College of Chemistry startups presented among 23 young companies last week at Berkeley SkyDeck’s annual Demo Day, where entrepreneurs pitched new devices, apps or inventions that, they hope, will provide big, bold fixes to the world’s problems, from climate change to disease.

Capturing carbon with inspiration from battery chemistry

May 7, 2022

The need for negative emissions technologies to address our climate crisis has become increasingly clear. At the rate that our planet is emitting carbon dioxide – adding about 50 gigatons every year – we will have to remove carbon dioxide at the gigaton scale by 2050 in order to achieve “net zero” emissions.

The urgent threat of climate change, driven by the burning of carbon fuels, requires bold and drastic action on a global scale. Communities in high-risk areas that are increasingly subject to natural disasters, such as recent wildfires in California and flooding in Texas, must adapt and relocate. Food supply chains are struggling as increased drought or volatile weather...
