What is “Green” hydrogen and why is it important? Global warming, caused by greenhouse gas (GHG) pollution from burning fossil fuels, is a major, growing problem causing $92.9 billion in US severe-weather damage in 2023. Minnesota has the second most severe US weather; check out your increasing home and car insurance rates to see how that affects you. 30% of the world’s GHG comes from heavy industrial manufacturing including fertilizer, chemicals, long-distance transportation (trucks, ships, airplanes), cement, paper, iron mining and steel production. Iron and steel production alone creates 8% of global GHG; a “green” steel alternative would solve 1/12 of global warming!
