Green hydrogen is emerging as a powerful solution in the fight against climate change, with the potential to decarbonise key industries worldwide, including in New Zealand. Produced by electrolysis using renewable energy, green hydrogen (GH2) generates significantly lower greenhouse gas emissions compared to grey hydrogen, which is derived from fossil fuels without carbon capture. However, the road to widespread adoption is fraught with challenges, particularly in cost and infrastructure.
If Australian households switched their hot water heaters to run off daytime solar power, it could lead to significant reductions in carbon emissions and lower energy bills, while maximising the benefits of cheap, abundant solar energy. Hot water heating is responsible for 15-30% of a home’s total energy consumption, second only to heating and cooling systems. A large proportion of Australian households use electric water heaters with storage tanks, which act like thermal batteries, storing more energy than many home battery systems. Traditionally, these heaters have operated during off-peak hours overnight, but shifting them to run during the day could help soak up excess solar energy, reducing waste and better matching supply and demand.
Starting November 2024, New South Wales residents and small businesses can access a new government incentive aimed at lowering the cost of battery storage installations. This initiative supports renewable energy adoption, reduces electricity bills, and helps the state achieve its ambitious environmental goals, including a 70% emissions reduction by 2035 and net-zero by 2050.
A significant announcement has just shaken the renewable energy community: Finn Peacock has informed the world that SolarQuotes has been acquired by Origin Energy. This news comes as a big surprise to many of us who have followed the company's journey. But as they say, all good things evolve, and perhaps this is less an end and more a transformative new beginning.
