We are a global consulting firm helping small and medium-sized companies with their sustainable business transformation.


NEA GREEN is the NEUMAN & ESSER company with a clear focus on consulting and services for the upcoming Hydrogen (H2) and Green Gases markets. Overall, the company’s target is to help customers with the decarbonization of their energy or industrial systems, and on decentralized applications. NEA GREEN first provides initial consulting and subsequent concept studies. If required, it supports our clients in structuring and financing hydrogen and/or biomethane projects. For example, NEA GREEN develops the business case together with the customer, calculates different scenarios and arranges offtake agreements for the purchase of the green gases produced. All of these steps are often necessary first, in order to make projects "bankable", i.e. financeable and thus realizable.
