Green hydrogen is used as fuel or raw material in power systems, transportation, and industry, which is expected to curb carbon emissions at the root. First, a unified energy system consisting of clean power generation systems, hydrogen energy systems (HESs), and transmission systems was proposed, and the characteristics of hydrogen load in different fields are analyzed. Possible business models for HESs in industry and transportation are then presented, cost and benefit functions for stakeholders of HES were created, and a business model with multi-party participation was modeled as a multi-objective optimization model. In a power system, the business model of combining two operating modes for hydrogen storage was proposed at the power generation side as well. Finally, three HESs were designed for a chemical plant with a hydrogen demand of 1000 Nm 3 /h, a hydrogen refueling station with a daily hydrogen load of 600 kg, and a 100% clean power generation system, respectively. The results of the case study show that one or more feasible business models (i.e., all stakeholders are profitable) can be found in both industrial and transportation by the HES planning approach proposed, while the internal rate of return of HES installed on the generation side is less than 5% due to high investment cost at this stage and low utilization rate; nonetheless, the profitable strategies are shown by 3D graphics.

13 business models to expand the hydrogen value chain. ... One approach being investigated in some sectors, for example steel (with the production of "green steel" widely seen to be an early, attractive use of clean hydrogen), is full value chain collaboration. In this, many more players both upstream and downstream are involved. ...
The supply of blue and green hydrogen is still small, but energy, natural resources, and industrial companies are beginning to explore how customers will use hydrogen. Economic feasibility will vary greatly depending on the availability of low-carbon alternatives, which will affect whether regions export or import blue and green hydrogen.
time for green hydrogen to mature and scale up Hydrogen is broadly used in industries but remains immature in the broader set of applications, for which cost reduction and innovative business models are required Most hydrogen business models require policy support, with heavy-duty transportation being the most promising one in the current context
For example, the industrial gas company Air Products has signed a 30-year agreement to become the exclusive off-taker for all green ammonia produced in Saudi Arabia by the NEOM Green Hydrogen Company. 3 When the project is up and running, Air Products expects to take 1.2 million tons of green ammonia per year and transport it around the world ...

sustainable hydrogen solutions, additional supply and therefore investment in production capacity is required. Detailed understanding of cost structure and investments are key to the business case of hydrogen By assessing business cases from current electrolyzer projects, it can be concluded that companies may not
13 business models to expand the hydrogen value chain. Deloitte's research finds innovative, real-life business model solutions that address these uncertainties. Some are present in the hydrogen industry today; others come from more mature energy industries that relied on business model innovation when they were in nascent stages of their own.
The Climate Business Plan also conservatively limits the use of pure green hydrogen to 10 percent, whereas some external estimates have ranged much higher. 1 Utility Dive, "Green hydrogen gets real as utility business models and delivery solutions emerge", March 2, 2020.
Gearing up for the green transition with digital transformation. As we work towards a low-carbon future, digital transformation represents enormous opportunity and promise. ... Prepare a hydrogen business case that thoroughly explores and creates optionality, business models, technical feasibility, financial viability, scalability to meet ...
