The CrossCut project will demonstrate how fuel cell systems in collaboration (hybridization) with renewable energy sources and with energy storage solutions can support the Danish and Global energy goals of substi-tuting fossil energy sources and how standardization and simplification can drive down production cost.
The project is cutting across existing distributed (renewable) energy technologies in combination with fuel cell system applications in the range of 2.7 - 10 kW. This power range is chosen because CrossCut has the ambition to develop, test, evaluate and demonstrate in real environment a cost effective hybrid FC system with special focus on optimization of the FC power conversion and the interfacing power management with solar PV, battery storage and other possible renewable sources.
From earlier projects and from customer experience so far, the overall request for extra reliable, cheaper, simpler and durable solutions for easy integration with other energy and storage technologies is given for all products and market segments for this fuel cell power range.
The idea of standardizing components is to create an industry best practice for fuel cell systems and sub-systems for different products and targeting different customers. The aim is to define a “one-type-fits-all”-kind of basic system in order to drive up volume reduce complexity and supply security of the key compo-nents, which essentially leads to reduce cost and strengthen the component industry to secure supply in the future.
The common challenge across market applications for fuel cell systems is in general the availability of standardized power components (power conversion, AC/DC, DC/DC and DC/AC) as well as the power man-agement components (controls, monitoring) in relation to the integration of fuel cell systems with other energy components (integration with PV, Batteries, Supercapacitors, Windpower, etc.)
As with any other technology, the fuel cell technology has to play the right role in the right setup with the right integration to be competitive. As fuel cell technology excels on reliability, flexibility, zero emissions, no hazardous substances and efficiency, the integration of fuel cells in energy systems has to be done where the maximum impact can be obtained at the lowest cost.
Despite the major development within fuel cell technology and the verging market-breakthrough, it is im-portant that the fuel cell system, as with any other technology, play the right role in the right setup. Thus, there are some challenges that the CrossCut project needs to accommodate.
