Not that climate change is a really big issue, but this is kinda interesting:

"This work introduces a strategy by synergizing green hydrogen technologies with bitcoin mining operations to address the concurrent challenges of cryptocurrency growth and climate change. We highlight the potential of this dynamic duo to enhance the deployment of renewable energy sources, particularly solar and wind power. By proposing a framework incorporating blockchain-driven crypto-applications with sustainable energy solutions, this work underlines the transformative potential of emerging technologies in the global pursuit of climate sustainability. Supported by appropriate policy measures, this integrated systems approach can augment renewable power generation and carbon offsetting capacities, advancing toward a sustainable and climate-resilient future."
