But the technology needs to ramp up greatly to play a significant role in providing an alternative to fossil fuels. This creates steam that powers electricity-generating turbines. 5/GEOTHERMAL POWER PLANTS Geothermal power plants tap heat up to 700 degrees Fahrenheit far below the Earth’s surface. Saudi Arabia, the world's largest oil exporter, is planning a $5 billion plant at its futuristic city NEOM to produce clean hydrogen. The holy grail is so-called clean hydrogen produced with wind, solar or nuclear power – today’s “grey hydrogen” is made with fossil fuels. 4/HYDROGENLong used in rocket fuel, hydrogen can be mixed with natural gas to make a cleaner-burning fuel, or used in a fuel cell vehicle, releasing water vapor as exhaust. Proponents say the high costs will fall as the technology improves. Sounds impressive, but that is only about the amount that comes out of the tailpipes of 2,000 cars. It is one of 15 direct air capture plants in the world that together suck about 9,000 tonnes of CO2 a year out of the sky. 3/CARBON CAPTURE AND STORAGE Last month in Iceland, Climeworks AB partnered with carbon storage company Carbfix to open the world’s largest plant to suck carbon dioxide out of the air and pump it underground where it becomes rock. In the U.S., Bill Gates wants to build a Natrium reactor in Wyoming for about $1 billion and have many of the plants providing power to the grid in the 2030s. Critics also say they will create more concentrated waste and would run on enriched uranium, which could make some advanced reactors and their supply chains attractive to bad actors. But advanced reactors are a challenge to build. They could theoretically be used in remote locations, complement wind and solar power, and some versions could use nuclear waste as fuel. However, no facility has yet performed a fusion reaction that releases more energy than it requires – the usual fuel hydrogen must be heated to 150 million degrees Celsius.2/ADVANCED NUCLEAR Advanced nuclear plants would be smaller than today's massive nuclear reactors. That leads them to fuse into a new larger atom, giving off enormous amounts of energy in the process. It works when the nuclei of two atoms are subjected to extreme heat. Here are some of the technologies drawing the most attention.1/FUSION Fusion is the process that fires the sun. Traditional clean energy sources like solar and wind power are expected to play a leading role in helping countries reach near-term emissions reduction goals, But it’s the higher-tech solutions, like fusion and advanced nuclear plants, that could play a crucial role in longer-term energy plans. "e will visit you soon in Grünheide," Diess said, referring to the Tesla plant on the verge of opening in Germany. Whether Musk's presence signaled anything more than pleasant comradery between the two makers of electric vehicles was left open-ended. Musk's drop-in chat on Thursday was the latest friendly gesture between the two chief executives, following Diess's trolling of Musk on Twitter earlier this year. "Big responsibility at a crucial point for our company."

"Good meeting with 200 top managers in Alpbach," Volkswagen Chairman Herbert Diess said on Twitter on Saturday, sharing a photo of Musk on a video call. Tesla CEO Elon Musk beamed into a meeting with top Volkswagen executives in Austria to explain how Tesla streamlines its supply chain. "Happy to hear that even our strongest competitor thinks that we will succeed," Diess said. Musk joined the conference by video, dispensing advice on management and supply chains.
