The next 30 years are crucial for addressing the global climate crisis. To limit warming to 2°C and sustain human life on Earth, we need to reduce global emissions by 25 to 55 percent by 2050. As the largest per capita emitter of CO2, the United States has a responsibility to lead in clean tech innovation.
The recent bipartisan infrastructure bill has authorized significant funding for clean energy and grid investments, as well as electric vehicle charging stations. However, dispersing funds across various research and development efforts may slow progress. That’s why we believe focusing on specific areas and institutions through net-zero innovation hubs can accelerate advancements in decarbonizing heavy industries, creating a resilient supply chain for critical minerals, and developing a clean energy workforce.
Clean tech innovation holds the key to a sustainable future. By embracing groundbreaking eco-friendly technologies and investing in research and development, we can lead the clean energy transition and pave the way for a greener, healthier planet.
Decarbonizing Heavy Industries for a Sustainable Future
Heavy industries such as steel, cement, iron, and aluminum play a significant role in global CO2 emissions. As the demand for these materials continues to rise due to infrastructure development and green energy initiatives, decarbonizing these industries becomes increasingly vital.
Fortunately, there are innovative pilots and technologies that show promise in achieving emissions reduction in heavy industries. Kiln electrification using plasma technology, biomass, or hydrogen has proven to be technically feasible, offering a path towards cleaner production processes. In the steel industry, hydrogen can be employed to eliminate CO2 emissions from the iron ore reduction process.
In addition, carbon capture, utilization, and storage (CCUS) techniques, such as calcium-looping technology, are being explored to remove CO2 from exhaust streams, enabling its storage or utilization in other processes. These innovative solutions are essential to reducing emissions and achieving a sustainable future.

Building a Resilient Supply Chain for Critical Minerals
The clean energy transition relies heavily on critical minerals like copper, lithium, nickel, cobalt, and rare earth elements (REEs). These minerals play a crucial role in the production of renewable energy technologies, such as solar panels, wind turbines, and electric vehicle batteries. However, the current global supply chain for these minerals is vulnerable, with limited domestic production in the U.S. and control held by a few countries.
To ensure a steady and sustainable supply of critical minerals, we need to innovate and diversify the supply chain. This involves exploring alternative sources and technologies, such as opening more mines in the U.S. for REEs, developing recycling and recovery techniques, and utilizing advanced extraction tools. By reducing our reliance on a few countries and diversifying the sources of these critical minerals, we can mitigate geopolitical vulnerabilities and create a resilient supply chain.
One key aspect of building a resilient supply chain is increasing domestic production. Encouraging and supporting mining operations for critical minerals within the U.S. will reduce our dependence on foreign sources, enhance national security, and create new jobs in the mining industry. Alongside increased domestic production, we should also focus on developing recycling and recovery technologies to extract critical minerals from discarded electronic devices and other waste streams. This circular economy approach will not only reduce the need for new mining operations but also minimize environmental impacts.
Investing in research and development to improve extraction methods is another crucial aspect of building a resilient supply chain for critical minerals. By developing advanced technologies and techniques, we can extract minerals more efficiently and with minimal environmental impact. This includes the use of innovative processes such as bioleaching and phytomining, which utilize natural organisms or plants to extract minerals from ore bodies.
