ABUNDANCE OF RAW MATERIAL
Thanks to the new, highly efficient enzymes from Novozymes, and an additional development of DONG Energy called ”Inbicon technology”, Maabjerg Energy Concept (MEC) will be able to produce the 73 million litres of 2G bioethanol, based on only 300000 tonnes of straw – 100000 tonnes less than previously estimated.
The potential of straw has been carefully examined, and the consortium MEC group estimates that the 300 000 tonnes of straw can be gathered within a radius of approximately 100 km (80 miles) of the plant in Måbjerg which is situated between Struer and Holstebro (Denmark).
The straw will primarily come from fields where it was previously ploughed in. Nationwide there is 2 million tonnes of excess straw, 1.5 tonnes of which is found in Jutland where the plant is situated.
A portion of this straw will also come from other suppliers of CHP plants, as several of these are currently phasing out straw as a fuel. Up to 2015, around 300000 tonnes of straw has been phased out by the CHP plants. This corresponds to the amount that will be needed by MEC by 2018.
Furthermore, MEC has looked at markets in Poland, Germany, France and United Kingdom, and concluded that by using straw from these regions it will be possible to supplement straw deliveries without significantly higher costs. In this case, the straw will be compressed into pellets or briquettes, which will reduce transportation costs by up to 60 percent.
MEC is planning to establish a three- to five-year contract model for the straw supply. This can be supplemented by competitive bidding, in order to ensure the supply from domestic and foreign sources.
A straw storage facility will be established in close proximity of the production facility. A storage capacity of 2 400 tonnes is projected, which corresponds to 65 hours of continuous operation. In addition to this, it will be possible to build decentralised storage facilities.
The energy sector, the agricultural sector and the transportation sector all have 20 years of experience in respect of the gathering and transportation of straw for energy purposes. MEC is building upon and adding to this valuable experience.
- 73 million litres of 2G bioethanol
- 45 million m3 biogas, the greater portion of which is upgraded to sustainable natural gas (natural gas quality)
- Electricity for 18000 households in Holstebro and Struer
- Heating for 34000 households in Holstebro ans Struer
- 1250 jobs in the construction phase and at least 1000 permanent jobs
