Danish Society for Renewable Energy is registered at Companies Agency as a voluntary association with CVR no. 33797982 and address c/o Agro Industries A/S, Agro Food Park 13, DK 8200 Aarhus N, Denmark.
The association was registered 07.08.2011.
Danish Society for Renewable Energy is a non-profit association that aims to develop demonstration plants for the industrial production of sustainable energy carriers and to hand over the developed projects to one or more production companies able to built and operate the plants.
Biogas + upgrading 11,4 MWmethane. Expected energy yield calculated on biomass is just over 60 %.
Wind turbines 18 MW nameplate capacity. An annual average of 37 % is expected in Eastern Jutland
Hydrogen by electrolysis 5 MWel nameplate capacity. Emperical yield on energyLHV is 82 % at peak load.
Methane by Sabatier process.Theoretical yield on energyLHV is 84 %. Massive subsidies needed to compete with other methane sources.
Carbon Recycling. 3 MWmethane. Hydrogen is used more profitable for the reduction of carbon dioxide directly into methanol
Methanol works 5,1 MWmethanol comprising steam reforming af methane and methanol catalytic synthesis. Theoretical yield on energyLHV is 80 %.
Low Temperature District Heating (LTDH) system is defined as a
system, which can operate in the range between 50-55°C to 60-70 °C supply and 25-30°C to
40°C return temperatures.
Ulta-Low Temperature District Heating
(ULTDH) uses supply of 40 oC combined with decentral heating pumps for domestic hot water. Heat loss in the distribution falls below 15 %.

Hydrogen by electrolysis: 2 H2O → 2 H2 + O2 - Skalerbar elektrolyse
Methane by Sabatier reaction: CO2 + 4 H2 → CH4 + 2 H2O; ∆H = −165.0 kJ/mol - MeGa-stoRE; På Vej Mod Metansamfundet
Methane by anaerobic digestion: C6H12O6 → 3CO2 + 3CH4 - link
Methanol by methane reforming: CH4 + H2O → CO + 3 H2; CO + 2 H2 → CH3OH - link

Lower Heating Values (LHV) are applied.
Change in enthalpy over time ∆H is negative for both the methane forming Sabatier process and the overall reforming processes of methane into methanol. It is essential to capture this exothermic process energy and turn it into a usefull coproduct. Low temperature and in particular ultra low temperature district heating are excellent methods.
