Green hydrogen, on the other hand, is produced by electrolysis, a process that divides water into hydrogen and oxygen without carbon emissions. While SMR is proven to scale, electrolysis is not. The vision is that solar, wind, hydro, geothermal or any other renewable source would change that. The term “low carbon hydrogen” is essential here, because while all hydrogens burn without greenhouse gas emissions, the climate effects of different production methods are very different. The decline in the costs of renewable energy has generated a new wave of enthusiasm, as abundant and inexpensive energy, which many consider a prerequisite for the success of hydrogen, now seems achievable. The CCC`s zero technical report for the United Kingdom indicates that low-carbon hydrogen could be produced from fossil gases with emissions of about 0.3 kg of CO2 per kg, with a catch-up rate of 95%. By comparison, the IEA estimates a coverage rate of 90% of 0.9 kg of CO2 per kg of hydrogen, as shown in the table above. Last October, for example, as part of the H2@Scale program, the office launched two consortiums, the mile fuel cell truck (M2FCT) and H2NEW, to promote research on fuel cell truck technology or hydrogen production methods. In addition, the heat produced by nuclear reactors could have applications in hydrogen production by producing steam for more efficient electrolysis or fossil gas-based steam reform. The last statement is important in that it distinguishes “green” from “conventional” hydrogen. Hydrogen is usually characterized by colors, depending on how it is produced. The United States already has a significant annual hydrogen production capacity of about 10 million tons, according to the U.S.

Department of Energy, which is mostly used in refineries and other industrial processes. In an article on foreign policy published in October 2020, Professor Jason Bordoff, a former director of the U.S. National Security Council, described the risks that could be associated with the trade in hydrogen and ammonia at sea. However, Mao conducted a modelling study earlier this year, which found that 99% of container ships using the busy china-U.S. line could run on hydrogen, “with minor changes in fuel capacity or operation.” Hydrogen is currently a highly localized industry, 85% produced and used locally, in part because of the high cost of transportation. With most hydrogen being “grey,” it is the cheapest in low gas prices, such as the Middle East and North America. It may be cheaper to connect them to the grid, where production will be constant, but the cost of electricity will be higher and will include payment for the connection to the grid. If the grid is not fully decarbonized, it would also mean that hydrogen could not be described as “green.” Despite the current hype, there is nothing new in electrolytic hydrogen. – 100 MW of electrolyrors since the late 1920s for fertilizers and heavy water – 100 GWh of salt cavernification tanks since the 1960s – 4500 km of hydrogen pipelines What was missing today was a lot of low cost power. In this detailed Q-A – which contains a series of infographics, maps and interactive diagrams, as well as the views of dozens of experts – Carbon Brief examines the major issues related to the hydrogen economy and explores the extent to which it could help the world avoid dangerous climate change.

According to an article published last August in the journal Nature, Europe is already far beyond the United States in its desire to establish a thriving hydrogen fuel industry. However, despite various start-up projects, where hydrogen-based fuels are used in shipping, this capital-intensive industry is covered by a “deadlock,” according to a Shell report. Transport policy makers take a care of it
