Optimizing Your PtG Plant's Productivity, and Profitability.
Energy system dimensioning is a key factor in optimizing the productivity and profitability of a Power-to-Gas (PtG) production system. What factors do you think are important in energy system design?
In order to achieve competitive production revenues for Green Hydrogen, a tailored dimensioning of the components of a PtG plant and its Renewable Energy Source (RES) is crucial. In assessing projects, Greenbox carries out detailed simulations incorporating variables such as solar irradiance or wind speed, which dictate energy yields and potential plant site output. This assists us in precisely sizing PtG plant equipment and energy requirements.
The benefit of simulations described above, is that the energy of production, compression, and other key equipment such as an Energy Storage System (ESS; i.e., battery) can be assessed and incorporated into system designs effectively. This wholistic method of modelling also accounts for electric and mechanical energy losses, component degradation, and capital and operating expenditures used in calculating further project level economics.
Key in optimizing the levelized cost of hydrogen, is incorporating an ESS to ‘peak shave’ and store energy for electrolysis, when available energy is low or non existent. This strategy yields the optimal capital efficiency and balance of plant, relative to sizing a PtG plant for the peak renewable energy yield; see a typical load profile below, for a solar PV and electrolyzer pairing.
Greenbox is developing the MultiFlowH25 energy management system, which further optimizes system productivity. In tandem with diligent system dimensioning, the MultiFlowH25 system enhances the cost structure of green hydrogen production and delivery to the customer, making it highly competitive in use cases such as mobility. With the current price of hydrogen at €9,50/kg (at the pump in Germany), we see below how cost optimization leads directly to profit margin potential.
