John Kerry, President Joe Biden's climate envoy, is expected to announce at COP28 a global strategy in nuclear fusion. If it is produced using renewables like wind or solar power, as opposed to fossil fuel generated power, it is called green hydrogen. Governments and companies think green hydrogen could be a way to clean up hard-to-decarbonize industries like steel and cement-making and other industrial manufacturing. PwC said technologies like green hydrogen and reducing food waste have relatively high emissions reduction potential, but are receiving a small share of start-up investment. In 2023, green hydrogen got 3.9% of global climate-tech venture funding, while food waste got 0.7%, it said.
