Corporations and governments see the hydrogen economy as a key enabler of the transition to a carbon-neutral world. Though already an important industrial commodity, hydrogen demand is forecasted to skyrocket as it gains major new applications in hard-to-abate industries and in the global clean energy market. By 2030, capital projects worth more than $500Bn1 must come online to meet demand for low-carbon hydrogen. Engineering teams face the major challenge of conceiving, designing, and executing brownfield and greenfield projects on time and within budget while both technology and markets undergo rapid change. From first concept to capital project execution and operations, engineering the hydrogen plant of the future requires innovation, agility, and collaboration. AVEVA’s engineering solutions build comprehensive digital twins that help engineers turn bold promises into results. Promises have been made. Promises of gigatons. Promises of terawatts. Most importantly, promises of zero. As in, net-zero carbon emissions by 2050. One after another, leaders from industry and government have announced bold visions for carbon-neutral economies. In the industry that used to call itself oil and gas, the word on everyone’s lips is now hydrogen. This colorless gas is the key to a green future for industries that are otherwise difficult to decarbonize. With pressure from investors and regulators, CEOs have committed to capturing this opportunity. Now it falls to engineering to translate commitments into designs, projects, and an operational hydrogen economy.
