Procuring Energy, Spurring Innovation Holds Potential to Secure Humanity's Future
As the world grapples with the challenges of climate change, governments are investing heavily in Carbon Capture and Storage (CCS) technology and other sustainable energy solutions, aiming to bridge the gap between current fossil fuel dependence and future renewable dominance. This article explores the current advancements and future prospects of these technologies, based on the latest trends and government initiatives as of mid-2025.
### Advanced Nuclear Energy
The US government has set ambitious goals to significantly expand nuclear energy capacity from about 100 GW in 2024 to 400 GW by 2050. This includes funding and regulatory streamlining for innovative nuclear technologies such as microreactors, small modular reactors (SMRs), and Generation IV reactors. These technologies promise enhanced safety, efficiency, and lower costs. Research leaders like Argonne National Laboratory are driving global collaboration and technical innovations in nuclear energy to meet increasing electricity demand reliably and affordably. The focus is on leveraging nuclear power as a resilient, secure, and carbon-free energy source critical for national security and economic infrastructure, including AI and military applications.
### Green Hydrogen
Green hydrogen is widely recognized as vital for decarbonizing sectors where electrification is challenging (industry, heavy transport). The development of renewable-powered electrolysis facilities is accelerating globally, benefiting from falling renewable energy costs (solar, wind). Green hydrogen's role is expected to expand synergistically with renewable generation, serving as energy storage, fuel, and feedstock.
### Sand Batteries
Sand batteries represent an emerging thermal energy storage technology using heat-storing sand to retain and dispatch energy. These systems can help smooth out renewables’ intermittency and provide long-duration, low-cost storage. They hold promise for future integration with renewable and nuclear generation to enhance grid stability over long periods.
### Solar Canopies
Solar power is rapidly expanding with improvements in photovoltaic technology and cost declines. Solar canopies, which involve installing solar panels over parking lots or urban infrastructure, increase solar deployment without requiring additional land. These installations contribute to decentralized energy production, grid resilience, and urban sustainability, empowering communities and reducing grid load.
### Offshore Wind Farms
Offshore wind is experiencing rapid growth, especially in regions with strong, consistent wind resources like the North Sea, US East Coast, and China’s coast. Offshore wind farms benefit from higher capacity factors and can deliver significant scalable clean power, expected to supply over 15% of global electricity by 2040 according to the IEA. Integration with grid modernization efforts, including enhanced transmission and storage, will be key to maximizing their role in sustainable energy systems.
### Outlook for the Next Two Centuries
These technologies form a multi-faceted sustainable energy ecosystem with the scalability, flexibility, and resilience required to meet humanity’s energy needs sustainably over the next two centuries and beyond. Strategic government support, technological innovation, grid modernization, and international collaboration will be crucial to realizing this vision. Green hydrogen, produced using renewable electricity, is emerging as a critical clean fuel for hard-to-decarbonize industries like transportation and steelmaking. By prioritizing research, collaboration, and large-scale deployment of these solutions, we can build an energy system that secures humanity's survival-and prosperity-for generations to come. The next two centuries will demand unprecedented innovation in how humanity produces and consumes energy.
