Low-carbon options for heavy industry like steel and cement are scarce and expensive<\/a>. Vox<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Climate activists are fond of saying that we have all the solutions we need to the climate crisis; all we lack is the political will. This is incorrect. There are some uses of fossil fuels, that we do not yet know how to decarbonize.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Take, for instance, industrial heat: the extremely high-temperature heat used to make steel and cement.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Heavy industry is responsible for around 22% of global CO2 emissions, with 42% of that \u2014 about 10% of global emissions \u2014 from combustion to produce large amounts of high-temperature heat for industrial products like cement, steel, and petrochemicals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To put that in perspective, industrial heat\u2019s 10%&nbsp;<a href=\"https:\/\/energypolicy.columbia.edu\/research\/report\/low-carbon-heat-solutions-heavy-industry-sources-options-and-costs-today\">is greater than the CO2 emissions of all the world\u2019s cars<\/a>&nbsp;(6%) and planes (2%) combined. Yet, consider how much you hear about electric vehicles. Consider how much you hear about&nbsp;<a href=\"https:\/\/www.vox.com\/the-highlight\/2019\/7\/25\/8881364\/greta-thunberg-climate-change-flying-airline\">flying shame<\/a>. Now consider how much you hear about \u2026 industrial heat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not much, I\u2019m guessing. But the fact is, today,\u00a0<strong>virtually all of that combustion is fossil-fueled, and there are very few viable low-carbon alternatives. For all kinds of reasons, industrial heat is going to be one of the toughest nuts to crack<\/strong>, carbon-wise. And we haven\u2019t even gotten started.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2026click on the above link to read the rest of the article\u2026<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fossil-fueled industrial heat hard to impossible to replace with renewables Preface.
