Reliable M Series for PEM Electrolysis Products from Nel Hydrogen

As the supply of renewable energy to the electricity grid increases, the ability to match the intermittent supply with demand becomes more and more problematic for power plant operators. As the deployment meets and exceeds 20% capacity, which some countries and regions already experience, grid balancing problems become acute, causing the curtailment of wind. This factor is driving the need to look for long-term, large-scale energy storage solutions.

Nel Hydrogen continues its successful history of using reliable and safe PEM electrolysis products at relevant scale for traditional and emerging markets by adding the M Series product to its portfolio. The M Series is an innovative ground-breaking product that has the capacity to integrate renewable sources of production, convert excess electricity to produce hydrogen and store it as energy for future use.

It is sized at a scale that can accept 1 and 2 MW of power and generate nearly 1000 kg of hydrogen per day. The resulting hydrogen can be injected into the natural gas grid (Power-to-Gas) and can be used for hydrogen fuel cell vehicles, biogas upgrading and industrial applications.

The scalable and modular M Series platform makes it an easy option for project managers, who are looking for a solution to meet their energy storage requirements, whether at two MWs or larger.

The M Series product was developed with quick, dynamic response in mind, in order to be adjusted to the irregular nature of renewable energy input. It can use excess renewable power and convert it into hydrogen, which can be stored for long periods for subsequent use as a fuel for mobility, heat and power generation.

Power-to-Gas technology provides the means to store and transport energy, unlike conventional storage technologies. With the existing storage facilities such as the associated underground storage and natural gas pipeline network facilities, the stored energy can be released where and when it is required most.

Energy Storage High Capacity Hydrogen Systems M Series PEM Electrolysers

As the demand for power increases globally, power grids, energy resources and the environment are facing a variety of challenges that often result in greenhouse gas emissions, increased indirect costs on society and high levels of pollution. There has been a shift to deploy renewable technology to meet various demands of the industry, providing sustainable green energy.

Unlike conventional grid power, renewable energy is often unpredictable or unavailable, causing mismatch between the periods of supply and demand. Costs of solar and wind are also approaching grid parity, prompting further penetration of renewables onto an aging infrastructure. This factor is also driving the need for high-capacity energy storage solutions.

Hydrogen produced using PEM electrolysis technology is the solution to fully leverage renewable energy.

As an energy carrier, hydrogen provides daily to seasonal storage and creates a reliable source of dispatchable green energy for the current and future needs of society. With the storage capacity of pumped hydro and the response time of a battery, PEM electrolysis provides the interface to convert excess energy from variable solar and wind power into hydrogen, which can be turned back into electricity when required, or used as a high value chemical feedstock to support a range of industrial applications.
