About Marble
Marble is a pioneering climate tech venture studio committed to combating climate change through innovative solutions. We collaborate with scientists, engineers, and industry operators to build companies that tackle significant climate-related challenges across the globe.
Our inaugural cohort of 12 companies is developing groundbreaking products in the fields of energy, industry, agriculture, and climate resilience, achieving remarkable success in securing follow-on investments. We are eager to partner with extraordinary individuals to launch our next venture.
Transforming Geothermal Energy
As electricity demand is projected to surge dramatically in the coming decade, we face the urgent need for new generation capacity that exceeds current build rates. The United States alone anticipates a rapid growth in load by 25% by 2030, driven by electrification and the expansion of data centers, AI infrastructure, and industrial development. This surge in demand necessitates a substantial increase in clean, reliable power, a need that next-generation geothermal energy is uniquely equipped to meet.
Despite the vast reserves of geothermal heat available, much of it remains untapped. Traditional vertical wells struggle to access geothermal reservoirs, particularly in low-permeability or complex geological settings. Enhanced Geothermal Systems (EGS) have broadened resource potential but face challenges such as water consumption, thermal breakthroughs, high expenses, and community and regulatory pushback due to concerns about induced seismicity. Currently, geothermal contributes to less than 1% of global electricity, despite estimates from the International Energy Agency (IEA) suggesting a potential of up to 800 GW by 2050.
Your Role
As a Founding Reservoir Engineer at our next-generation geothermal company, you will play a crucial role in redefining our subsurface strategy. Your expertise will guide the development of innovative well architectures designed to enhance reservoir contact and heat extraction significantly.
By accessing a larger effective rock volume, we anticipate achieving 2-3 times greater well productivity. Coupled with meticulous drilling practices, our goal is to lower costs and work towards a target Levelized Cost of Energy (LCOE) of $50/MWh.
We have already mitigated fundamental technical risks, begun collaborations with key technical partners, and pinpointed potential sites for pilot projects and groundbreaking initiatives.
