The 'Biomass and Wind to CHP' concept is illustrated by Figure 2. Methanol and ethanol are produced in a plant converting biomass and electricity into methanol and ethanol. The ethanol is produced by fermentation of biomass.

The by-product from the fermentation, which is called the non-fermentable, is gasified with pure O₂ into a mixture of H₂, CO and CO₂.

An electrolyser unit delivers the O₂. Hydrogen from the electrolyser is mixed with the syngas leaving the gasifier.

The gas mixture is used to produce methanol, which is stored as a liquid under normal conditions.

The methanol is transported by truck to a local storage and reformer station located close to the cluster of households that are equipped with fuel cell systems for combined heat and power supply. The methanol is reformed to pure H2. The hydrogen is transported from the reformer station to the household through a hydrogen grid.

The hydrogen is converted to heat and electricity by a fuel cell CHP in the household.
