A decade ago, China used low prices to dominate solar manufacturing, wiping out Western competitors just as worldwide demand for panels started to soar. The US and Europe are determined not to let the same thing happen with hydrogen.As the world sprints to decarbonise, the next round of competition revolves around a device called an electrolyser. Plug these into clean electricity such as solar power, and it’s possible to extract hydrogen from water without producing any planet-warming emissions. That’s a crucial step in creating a green fuel capable of decarbonising such industries as steel, cement or shipping. Companies around the world are already revving up electrolyser production, green hydrogen plants are under construction, and the industry is finally making the leap from pilot projects to industrial scale. BloombergNEF, a clean energy research group, estimates worldwide…
