The CEOG project demonstrates McPhy’s technological expertise and ability to help scale up hydrogen solutions.

The CEOG West Guyana Power Plant project, led by Meridiam, HDF and SARA, is the world’s largest power plant project combining photovoltaic energy and massive 128 MWh storage, mainly in form of hydrogen.

McPhy will supply the 16 MW hydrogen production platform, which will be commissioned in 2024. It will be equipped with the innovative “Augmented McLyzer” technology: a unique combination of high-pressure alkaline electrolysis (30 bar) and high current density electrodes. Powered from water and green electricity produced by the photovoltaic park, this platform will allow the production of nearly 860 tons of green hydrogen per year and will prevent the emission of 39,000 tons of CO2 per year compared to a fossil power plant (1).

Combining both a photovoltaic solar park, a multi-megawatt electrolyzer, a hydrogen storage unit and high-power fuel cells, CEOG plant will produce hydrogen that will be stored under pressure in tanks. This production will ensure the supply of electricity to 10,000 homes in Guyana, at a competitive cost compared to thermal power plants in the region, and without emitting pollution.

This world first represents a decisive milestone for the industrialization of the hydrogen sector.

McPhy offer tailor-made solutions to ensure a balance between energy supply and demand in the In the China Hebei province’ networks.

The solution delivered to Hebei Province is a compact 4 MW hydrogen generation equipment including two McLyzer 400-30 modules, transformers, power electronics, a purification and drying unit, as well as a solid-state storage module, initiating a complete chain of renewable electricity surplus valorization in the heart of China.

The McPhy system converts and stores renewable electricity surplus produced by a 200 MW wind farm into clean hydrogen. This project represents a major reference for McPhy, which confirms its ability to execute projects for the massive conversion of renewable energy into hydrogen for injection into the grid or as a raw material. As well as its ability to manage major international projects.

Perfectly adapted to the variability of renewable energies, McLyzer rapid response electrolyzers offer energy companies a relevant solution to ensure the stability of electricity networks.

This project provides an efficient and competitive answer to the issues raised by renewable energies, which are intermittent in nature and need adapted storage and valorization solutions.

“This project will contribute to the development of renewable electricity sources in Germany, the world’s second largest renewable energy producer, by offering a competitive solution to valorize to production surplus”

Located at the Berlin Airport, this demonstration project is designed to produce “green” hydrogen from a surplus of wind power using an electrolyzer and using solid-state storage to create a hydrogen cogeneration plant and hydrogen filling-station infrastructure for buses and cars.

Renewable energy from the Enertrag wind farm near the new airport in Berlin will be converted into hydrogen by a McPhy electrolyzer, to smooth out energy fluctuations and store surplus wind energy.

Total and Linde will build the infrastructure necessary to distribute this fuel to buses and automobiles powered by fuel cells.

In addition, new-generation McPhy solid-state hydrogen-storage will allow the 2G power station to provide electricity or heat from stored hydrogen, flexibly and on demand.

The interests of this project are multiple:

• To produce zero-emission fuel for cars or buses running on hydrogen and/or supply other hydrogen filling stations.
• To re-inject surplus renewable energy into the natural gas network or the power grid.
• To optimize a system that is subject to high constraints with regard to electrical power supply and implement several technological elements.

The objective of the project is to evaluate and validate the technical and economic relevance of home energy solutions using a natural gas and hydrogen component.

Launched in 2014, GRHYD is a project to inject hydrogen into the territory’s natural gas distribution network in order to meet the needs of the residents of the new neighborhood of Cappelle-la-Grand in terms of heating, hot water and cooking. Approximately 100 homes are supplied with a mixture of hydrogen and natural gas, in variable proportions of hydrogen and less than 20% by volume. The objective of the project is to evaluate and validate the technical and economic relevance of home energy solutions using a natural gas and hydrogen component.

GRHYD is coordinated by ENGIE in association with 10 other partners, it’s supported by the government as part of the Future Investment Program operated by ADEME and labeled by the Tenerrdis competitiveness cluster.

As the first Power to Gas demonstrator in France, GRHYD represents a large-scale demonstration stage, which is the necessary transition between the previous experiments and the ambition of future industrialization of this process.

Inaugurated in 2018, the experimentation ended in 2020.

McPhy plays a key role in this project, since the company gives its support based on its considerable expertise in solid-state storage technology to establish its feasibility “at large scale” (750kg of hydrogen stored); and also to demonstrate the economical relevance of the business model generated.

McPhy supplies

• Five storage units
  Each one presenting a hydrogen storage capacity of 150 kg, our HDS150 contain the McPhy
  Energy disks. The blocks are transportable and, once filled, will be transported to the
  final user.
• Three hydrogen loading stations
  Installed on the INGRID site, they allow the McStore blocks to be filled with the hydrogen produced by the on-site electrolysis unit.
• Unloading station
  Installed on the final Customer’s site, this unit allows the blocks to release the stored hydrogen and use it for new energetic applications.

Commissioned at the end of 2016, INGRID is a unique platform, a showcase for solid-state hydrogen storage technology.

The platform combines various electrical production facilities, among which a photovoltaic array. There, our McLyzer 10-10 produces “green hydrogen” to manage the power fluctuations of intermittently available renewable energy sources and to send power back to the micro-network in the evening.

A second tender process will soon allow the installation to be completed by a hydrogen storage solution, such as LTS / McStore.

If the results are conclusive, hydrogen energy is expected to address new fields of application such as hydrogen mobility and will, hopefully, be disseminated throughout the “Island of Beauty”.
