We believe in sector coupling, creating cross-technology and cross-industry synergy effects in order to tackle the key challenges of cyber-physical systems, IoT and Big Data for you. We are convinced that hydrogen is playing a key role as a green energy solution to replace the traditional carbon cycle: green hydrogen is not a future idea, it is reality and Greenbox is already offering the implementation of decentralized scalable green hydrogen plants. We let you independently supply your own vehicles, produce your own plant fertilizer or enter the market as a green hydrogen provider.
We offer a wide range of sustainable energy management solutions, from consulting support to turnkey projects for operators. Our solutions aim to enable clean and competitive energy production, conversion, storage and service systems. To reach this goal we combine Renewable Energy Sources (RES) with leading storage and conversion technologies. Our Planning and Control tool is able to specify the right architecture for the specific project and further will control and optimize the final live implementation. With our AI based prediction algorithm we are able to reach up to 25% productivity gains compared to state-of-the-art installations.
This productivity advantage enables a wide range of innovative business models such as off-grid energy supply, grid balancing services, peak shaving, green hydrogen supply and super fuel production.
Together with leading system partners throughout the energy and infrastructure value chain, we are providing sector coupling solutions for smart city energy management, TCO optimized mobility systems, energy market facilitators and others.
Products and Services
The core of our innovation is our Greenbox MultiflowH25 intelligent control system that applies power balancing algorithms based on self-learning smart predictive models to ensure the most productive system operation. Greenbox MultiflowH25 generates productivity advantages with an impressive result of up to 25% total cost improvement to locally produce green hydrogen.
The MultiFlowH25 System determines the specific dimensions for each component in Power to Gas (PtG) installations so that attractive business models with a long-term profitability and sustainability are guaranteed. Each of our applications is absolutely fitted to the individual use case. The starting point for such a system can either be demand driven for example by the customers yearly demand for H2 or based on supply capacity and profile for example around an already active renewable energy source (e.g. wind, solar, hydro). After determining the perfect fit for the specific use case, Greenbox will provide a complete implementation proposal including the complete business plan from investment scheme to operational model and costs.
The key innovation of our MultiFlowH25 System is to keep the interplay between the dynamic load curve of a RES, the power sourcing for a downstream energy storage system (ESS), the PtG and GtP components and hydrogen storage at its highest efficiency in regard to the economy, the life cycle of the whole system and the maximization of H2 production. Applying such a system optimization, we are the enabler for a new generation of business models in energy management.
Our systems are fully connected: real-time data from all our systems are collected and analyzed for a continuous improvement process concerning system efficiency and lowering cost through predictive maintenance. Data analytics constantly keep our systems on the peak of their efficiency and environmental data forecasting (weather, supply, demand, pricing) is pushing the system way ahead of competition. The users of the Greenbox MultiFlowH25 system will always benefit from the newest technologies on the market.
What can you expect from us: We either build your customized Plug&Play H2 Power Plant or enter into a purchase power agreement (PPA) with you to secure your energy market business model.
Second Life Energy Plants
Renewable energy power plants, which have lost their claim to the EEG apportionment after 20 years, are facing the crucial decision of either continuing their operation of feeding electricity into the grid, but at a much lower remuneration (often below the breakeven point), or completely dismantling the power plant at a significant cost.
Greenbox offers a very attractive solution to continue operation with the prospect of getting high and stable returns that ensure operational profit for another 10 to 20 years. This alternative is based on the production of green hydrogen from the renewable energy power plant. For this use case, Greenbox offers a complete plug-and-play solution either as an investment addition to the existing facility or as a PPA model.
Another use case based on the production of hydrogen is to offer a grid balancing service to the public grid. Grid balancing is when excess electricity from the grid is locally stored (in our application in form of H2) and then fed back into the grid as soon as demand for electricity exceeds supply. Grid balancing will increasingly become a necessity as the percentage of renewable energy rises in the energy mix. Demand for energy in the grid does not overlap with the real-time supply from renewable energy, so a form of energy storage is an absolute necessity. While hydrogen is widely regarded as the future solution of energy storage, our Greenbox MultiflowH25 system makes hydrogen the solution of your Grid balancing business model today- competitive, sustainable, reliable and feasible.
Emission-free CHP Solution
Fuel Cells convert Hydrogen back to Electricity. But in addition to Electricity also heat is being generated. This builds the basis for combined heat and power (CHP) solutions. For this use case, we are able to plan and implement a complete system combining on-site upstream production of hydrogen with Electrolyzers and a stationary fuel cell for the conversion of hydrogen to electricity and heat. Due to the simultaneous usage of electricity and heat, the parametrics of the fuel cell can be ideally utilized so that system efficiencies close to 100% are feasible. This whole process would take place without generating one single gram of CO2. Our MultiflowH25 system will always ensure an optimized energy and heat supply to match the demand profile.
