PtX Sector Coupling and LCA

The purpose of the project is twofold:
1. To further develop existing energy systems and LCA tools, methodologies and
models to better determine optimal PtX-integration into the green transition
2. To use these models for assessments relevant to defining the optimal locations of
new plants based on grid capabilities, market forecasts, biomass and carbon
availability and including sector coupling and co-optimisation of gas, electricity,
hydrogen and district heating

The optimal placement of PtX plants will depend on the availability of resources (wind
and power, local biomass and CO2 sources) as well as the vicinity to energy
infrastructure (harbours, district heating grids, gas grids, power grids). Moreover, the
integration with green fuels and the value chain of various biomass conversion
technologies have an important role to play. An analysis will be made to illustrate the
importance of resources and infrastructure in terms of placement, environmental
performance, and profitability of plants taking into account the following themes:
‐ GIS data (e.g. from Energinet's hub and AAU’s Heat Plan Denmark 2021)
‐ potential tariff structures
‐ alternative and supplementing district heating production
‐ economy of scale and excess heat temperatures
‐ dynamics and demand-response potential of the PtX
‐ life cycle impacts related to system and technology choices
‐ potential excess heat for district heating
