About

Innovating at the Intersection of Engineering and Sustainability

EnviroMission is a next-generation energy company pioneering scalable, dispatchable, and commercially viable clean power solutions. Our patent pending STEGS™ technology stores solar thermal energy in an engineered thermal block, that is then converted to mechanical energy,providing round-the-clock energy generation. Unlike photovoltaic, wind, or CSP systems, STEGS™ can operate continuously, regardless of inclement and intermittent weather or daylight conditions.

Group’s EnviroMission’s international strategic partnerships with engineering, academic, and infrastructure leaders underscore our commitment to rapid, deployment of high-performance, net zero energy systems worldwide.

OUR SOLUTION

STEGS™: Groundbreaking Solar Thermal Power

At the heart of EnviroMission is the Solar Thermal Energy Generation and Storage (STEGS™) Block—a patent pending energy storage system that allows continuous reliable generation with more than 48 hours of full capacity storage.

Key Advantages:

  • 24/7 base-load electricity or capability to meet a demand profile
  • Modular scalability (1 MW to 500+ MW)
  • No need for water or batteries
  • Net-zero emissions
  • Standard power plant equipment – powered by the sun

Modelled with an advanced thermodynamic modeling program tool (DOVET™) and AI-enhanced optimisation, STEGS™ represents a leap forward in reliability, efficiency, and energy security.

FAQs

STEGS™ (Solar Thermal Energy Generation System) is EnviroMission’s proprietary renewable energy platform designed to deliver continuous, baseload electricity. It captures solar energy through advanced thermal collection systems, stores the energy in Thermal Energy Storage (TES) blocks, and converts it into electricity around the clock. This ensures reliable power supply even when the sun isn’t shining.

Unlike photovoltaic solar panels or wind turbines, STEGS™ is dispatchable—it can deliver electricity 24/7, regardless of weather or daylight conditions. By storing energy as heat and releasing it on demand, STEGS™ avoids the intermittency challenges faced by traditional renewables, strengthening grid reliability and reducing reliance on fossil fuels.

STEGS™ provides several unique benefits:

  • Baseload renewable power to replace retiring coal and gas plants.
  • Cost competitiveness, with a capital expenditure of around AU$3M per MW / AU$3M per acre.
  • Scalability and modularity, enabling deployments from small pilots to large-scale projects.
  • Community and economic benefits, including job creation, regional investment, and energy security.

STEGS™ has been designed with commercial viability at its core:

  • Lower development risk compared to older renewable technologies.
  • Strong ROI profile, with attractive capital efficiency.
  • Multiple deployment models, including direct ownership and licensing-based structures.
  • Alignment with government incentives, such as the US Governments Inflation Reduction Act.

STEGS™ directly addresses one of the United States’ most pressing challenges: the need for reliable, renewable baseload power to replace aging coal and gas infrastructure. By delivering dispatchable 24/7 electricity, STEGS™ provides grid stability and complements intermittent renewables like wind and solar PV. Its scalable, modular design makes it well-suited for deployment across diverse U.S. regions, from Renewable Energy Zones to industrial power hubs.

In addition, STEGS™ aligns with federal and state incentives, such as the Inflation Reduction Act (IRA) and Department of Energy (DOE) programs, which prioritize investment in advanced clean energy solutions. This positions STEGS™ as a homegrown technology capable of driving America’s energy independence, reducing carbon emissions, and unlocking long-term economic growth through jobs, manufacturing, and regional development.
