Overview
Green Hydrogen
Green hydrogen is a critical key element in our transition to low-carbon or zero-carbon alternatives for energy. The net-zero emission targets cannot be achieved without deep penetration of renewably and sustainably fuels.
As the electrolyser technology advances (particularly PEM electrolysers), the CAPEX costs for the green hydrogen projects have been reducing. However, the OPEX remains high due to irregularity and unpredictability of 100% renewable power generation.
Battery Storage for Green Hydrogen
Electrolysers require regular and reliable energy to work at maximum efficiency. Since green hydrogen requires 100% renewable energy, it is not always possible to ensure this constant supply of power. Furthermore, if the energy supply falls below a minimum level, the electrolysers must shut down and therefore produce no hydrogen at all. Therefore, renewable energy sources (PV or wind) must be sized significantly higher than rated power for the electrolysers, to ensure > 7000 operating hours in a year.
On the flip side, when production from PV or wind is high, the excess energy must be curtailed and therefore the project does not operate optimally. Lithium-ion battery storage for green hydrogen projects fixes this issue by storing excess energy and discharging the battery storage when energy from connected renewables falls below optimal levels. This means that the electrolysers are always working at maximum efficiency and the overall operating hours increased drastically.
For example, consider a project where a 2 MW wind turbine is connected to a 1.5 MW PEM electrolyser for green hydrogen production. In an isolated off-grid scenario and considering installation in southern Germany, the maximum levelized operating hours for the electrolysers are approximately 3,200 i.e. only about 36.5% operate during the year.
The levelized operating hours can be increased to > 4,600 with the installation of 700 kWh of battery storage, increasing the operation to more than 52%.
Intelligent EMS, Optimal Operation
HIS Energy Management System measures the energy flows throughout the connected network. It also monitors and stores load profiles and power generation profiles, and can forecast operational strategies. Connect your green hydrogen project with intelligent HISBatt EMS and ensure that the maximum green hydrogen is produced for your project, for maximum ROI
Do you have a Green Hydrogen project that requires an energy storage solution?
Hydrogen, more than Energy Storage and Fuel Cells
The cost-competitive green hydrogen produced in combination with battery storage can be mixed with natural gas, or used as transportation fuel, or chemical feedstock.
E-methanol produced from green hydrogen and captured carbon dioxide can be readily used in existing plants ensuring net-zero carbon emissions while sustaining the older processes and machinery. Methanol is one of the most important building blocks in the chemical and pharmaceutical industry. It is also used heavily for the production of synthetic hydrocarbons. Currently, more than 65% of the methanol is produced via natural gas and steam methane reforming.
Processing green hydrogen further to e-methanol, its derivatives are attractive for several sections. For example, the transport sector can use the same distribution and storage infrastructures as traditional fossil fuels while introducing an extremely clean alternative.

Green Hydrogen and Gas Network in Germany
Hydrogen can also be added directly to existing natural gas networks up to 30 percent without any restrictions for natural gas users or the gas distribution network. For example, EnBW’s operating site in Öhringen has been using a hydrogen and natural gas mixture since 2021. In Phase 2, the hydrogen mix was increased up to 30% and the nearby households have also been using this hydrogen and natural gas mixture for cooking and heating.
The green hydrogen phenomenon is on the rise and the combination of reliable LFP battery storage makes the production of green hydrogen more reliable and cost-competitive.
