Project InnerSpace Named Top-Five Climate Nonprofit for Fourth Year

BOSTON – November 06, 2026 -- Project InnerSpace, a geothermal-focused non-profit, has made Giving Green's Top Climate Nonprofits list for 2026-2027, its fourth consecutive year among the five organizations the evaluator ranks as most effective at driving long-term systemic change.

Giving Green cites financial de-risking plan for new geothermal projects

Project InnerSpace describes itself as a focused research organization (FRO). It aims to remove the major barriers to scaled global geothermal development by the end of this decade. In its report, Giving Green said it was impressed by the number of wins and connections the group has built in a short history. The evaluator also credited a plan to reduce financial risk for new geothermal projects.

Giving Green said the group's technical expertise lets it "influence capital well beyond its own budget."

Study Names 30 EU Industrial Clusters for Geothermal Heat Switch

MADRID – October 29, 2026 -- Thirty industrial clusters across 11 European countries could displace more than €850 million per year in fuel spending by switching to geothermal heat, according to a new analysis from Project InnerSpace and Future Cleantech Architects (FCA). The conversion would also avoid 4.3 million tonnes of CO2 emissions annually, equivalent to the emissions from more than nine million barrels of oil consumed.

Clusters span 11 EU Member States, with 152 more candidates identified

The report, Unlocking Europe's Geothermal Industrial Heat Potential, covers geothermal potential in every EU country. The 30 priority clusters are located in Austria, Belgium, Bulgaria, France, Germany, Hungary, Italy, the Netherlands, Poland, Slovakia and Spain.

The authors describe the 30 as a starting point. A wider pool of 152 candidate clusters could follow.
