Feasibility of complete composite geothermal well systems
report
Geothermal energy has great potential as a baseload heat source for district heat
systems for built environment. To improve the economics for large scale
implementation, technology and methods are explored to lower the Total Costs of
Ownership (TOC). Geothermal systems are currently mainly made out of steel and
therefore subjected to corrosion and deposits. This will result in high maintenance
costs for corrosion prevention (inhibitors), inspections and repairs which will reduce
uptime of the system. Not always recognized, but it will also raise the cost of energy
for circulation due to increased flow resistance. A non-corrosive material such as
Glass Reinforced Epoxy (GRE) material can reduce the cost of operation and the
risk of production shutdown for unscheduled maintenance and additional production
loss
