HiGradeGas - Highly Structured materials for upgraded biogas and storage

The vision of HiGradeGas is to overcome the barriers towards a wide-spread and
sustainable use of biogas in the Danish energy system by improving the cost
efficiency of (i) biogas upgrading and (ii) methane storage. The project will
facilitate the use of biogas as a versatile fuel that can be stored and used for
transport or injected into the gas net, and thereby increase the flexibility of future
renewable energy systems in Denmark. HiGradeGas proposes an innovative concept
in which adsorbents are nanostructured by advanced shaping technology. For
biogas upgrading, adsorbents will be granulated or electrospun into 3-dimensional
nanofiber network to improve upgrading performance, allowing a more than 20 %
reduction of cost for small scale industrial pressure swing adsorption units.
Moreover, the knowledge developed during electrospinning can be directly utilized
to structure nanofiber adsorbents on a conductive substrate and form a concept
device for biogas storage. Such a device will enable the low pressure adsorption of
biomethane, improve gas diffusion and heat transfer and thereby enable faster gas
adsorption/desorption cycles in an electrical swing adsorption unit. HiGradeGas is
structured in 4 work packages, including development of adsorbent, structuring of
adsorbents for biogas upgrading, a proof of concept of a multilayered device for
biomethane storage and a technology exploitation and implementation plan. Worldwide
recognized research groups and industrial partners (who are playing leading
roles in biogas upgrading and storage, advanced shaping and technology
exploration) will join their core expertise and ensure the implementation of project
results into industrial applications as well as a much stronger role of biogas in the
future Danish energy system.
