Zambian startup GEI Power offers hybrid solar home systems that integrate high-efficiency solar panels, pure sine wave inverters, MPPT charge controllers, and lithium battery storage. They supply stable, off-grid, and backup electricity for residential, commercial, and industrial use. Further, the systems optimize solar input using MPPT technology and store excess energy in lithium batteries for nighttime consumption or power outages.

Additionally, the startup manufactures methanol-fueled green cookstoves to reduce charcoal dependence and indoor air pollution. Thus, it advances decentralized solar power and green cooking solutions to strengthen energy access, improve grid resilience, and reduce environmental impact.

E2E Energy Solutions enables Geothermal Reservoir Recovery

Canadian startup E2E Energy Solutions develops a geothermal heat and power system that converts overlooked subterranean reservoirs into steady sources of baseload green energy. It applies the enhanced geothermal reservoir recovery system (EGRRS), which merges conventional geothermal and enhanced geothermal system (EGS) technologies, to repurpose depleted oil and gas wells and saline aquifers. The system injects fluid through a designated leg into a stimulated radiator, heats it, and directs it to the surface via a production well for energy conversion.

Further, the startup eliminates the use of surface water and lowers carbon emissions by reusing existing infrastructure such as pipelines, roads, and power lines. Thus, it converts previously uneconomic geothermal sites into viable assets, increases access to low-carbon baseload power, and supports a sustainable net-zero energy system.

Alotta builds Floating Photovoltaic Systems

Norwegian startup Alotta builds Alotta Solar Hybrid system, a floating photovoltaic system that reduces fossil fuel dependency in coastal and off-grid locations. The system captures solar energy and integrates it with existing sources such as diesel generators and battery storage to maintain continuous power.

Moreover, hybrid systems deploy quickly in remote areas with limited infrastructure and operate on water surfaces to avoid ecological disruption. It proves effective in aquaculture, adapts across sectors, and reduces fuel use and emissions to reduce operational costs.

AbSOLAR facilitates Inter-seasonal Underground Energy Storage

French startup AbSOLAR develops a green energy system that combines solar thermal energy with underground geothermal storage to provide carbon-free heat and cold. The startup builds and operates central solar on underground energy storage (C2SES) installations that collect solar thermal energy. It stores excess heat in the subsoil using borehole thermal energy storage.

Additionally, the green energy system uses the thermal inertia of rocks to retain heat for months. It also enables interseasonal energy use to address the intermittency of solar power. This conversion supports long-term decarbonization of heating and cooling in buildings, agriculture, and industrial sites.
