Connecticut's Department of Energy and Environmental Protection has unveiled the Connecticut Clean Hydrogen Roadmap as part of its efforts to combat carbon and greenhouse gas emissions. The roadmap aims to identify key drivers and barriers to clean hydrogen production and adoption in the state. ENGIE Impact, a consulting firm, has been hired to assess the feasibility of using hydrogen to reduce emissions. They emphasize the importance of sourcing electricity from renewable sources like solar and wind for environmentally friendly hydrogen production. The roadmap suggests that big vehicles, ferries, and container ships could benefit from hydrogen use due to the fuel cell technology involved. However, the conversion to hydrogen may not be suitable for airplanes. Despite the potential benefits, the roadmap indicates a significant requirement of 1.6 gigawatts of electricity, posing a challenge for Connecticut's energy supply. The state aims to cut 472,000 tons of greenhouse gases by 2040 through hydrogen adoption but would need to source a considerable amount of electricity from neighboring states. DEEP Commissioner Katie Dykes plans to promote hydrogen adoption by visiting businesses already using it and identifying areas where it can have the most significant impact. The overall sentiment of the article towards hydrogen is positive, highlighting its potential to contribute to Connecticut's emission reduction goals.
