Energy production, usage and distribution

In the search to bridge the gap between 'Energy' and 'Water,' the first step was to conduct an area survey in order to identify the demand for energy as well as the possible ways of producing it. This study adopted a global approach to the options for energy production, including the potential to produce biogas. Alongside these options, the study also analysed all current and pending energy projects in the region. This inventory operation took into account the region's current and future energy needs, and shows that the cities of Arnhem and Nijmegen will most likely not be in the position to achieve zero-carbon emissions within their municipalities. 'De Kop van de Betuwe' currently produces a great deal less renewable and non-renewable energy than it needs.

However, Park Lingezegen in the narrower sense and De Kop van de Betuwe in the broader sense should, in the future, be in the position to become a zero-carbon emissions area. This forecast is based on the predicted growth in biomass usage and the spatial opportunities in the area for wind and heat energy.

Together with the stakeholders in the area, RichWaterWorld has developed a vision for the region's self-sufficiency as far as sustainable energy is concerned. This vision highlighted that an initial priority on the journey to self-sufficiency is to develop and implement a regional Arnhem-Nijmegen heat grid instead of creating separate local heat grids for both cities. In formulating this vision, RichWaterWorld has made a contribution to the region's ambition to become an 'energy-neutral region in 2045'.

Biogas potential
The Waterrijk area and surroundings contain a number of municipalities around the large rivers in the Dutch province of Gelderland. The area stretches between Arnhem and Nijmegen, finally reaching the municipalities of Lingewaal and Zaltbommel. The biogas potential and the resultant quantities of biogas production have been identified with help from the energieatlas (energy atlas) of the Dutch province of Gelderland (in Dutch only). This atlas contains information about the potential of biomass for each municipality, subdivided into various sources of biomass. Only some of these sources are suitable for fermentation and biogas production.

The results from the calculation of the biogas potential in the area 'Waterrijk and surroundings' are listed in the table below. The table demonstrates that, should 50% of the suitable biomass in the area be used for biogas production, almost 11,000 households could be supplied with enough gas to cover their gas consumption, or 12,659 cars could be driven on biogas fuel.
