Abstract
Achieving the net-zero carbon emissions by mid-century has become a global goal, increasing the focus on cleaner technologies, green hydrogen stands out when tackling areas electricity alone can’t reach. This paper compares green hydrogen with solar power, wind power, and similar options, focusing on the key threats affecting its production compared to solar solutions. Rather than relying on just one path, the approach blends insights from over 20 vetted studies published between 2015 and 2025 found in Scopus, along with first hand thematic evaluation. Each technology gets viewed through six separate angles: how deeply they cut emissions across their lifespan, whether they make sense technically and financially including future price trends, where exactly they fit best, how well they link with existing systems, financial roadblocks slowing them down, plus shifts shaped by regulations and market forces. A perfect combination of solar, wind, and green hydrogen is more effective than only relying on one single technology. Some places may add other tools based on local needs. Together, these pieces support global climate goals along with cleaner industry and fairer access to energy services.
