Abstract: Global warming & Climate crisis are no longer predictions. The Earth's average temperature has clearly increased since the 1900s, a trend that aligns with global CO2 emissions. In 2015, under the Paris Agreement, many countries agreed to keep the Earth's average temperature below 2°C (ideally, 1.5°C) compared to pre-industrial levels. However, 2024 has already recorded 1.55°C.National Geographic published a news with title “2024 was the hottest year ever – but it might be the coldest year of the rest of your life.” Using fossil fuels as an energy source is one of the main causes of CO2 emissions, so utilizing renewable energy is essential to achieving net-zero emissions.Renewable energy comes from natural resources such as the sun, wind, geothermal energy, and water. The amount of renewable energy is much greater than what humans require. However, renewable energy has limitations: it is non-continuous and dependent on time and location. To overcome these limitations, it is mandatory to develop high-efficiency energy conversion and storage techniques. Batteries and hydrogen are the two main candidates for replacing fossil fuels as an energy carrier for storing renewable energy.The main field of storing renewable energy in batteries and hydrogen is electrochemistry, which involves reactions between electrons and ions. Although various studies have been conducted to improve performance and durability, most of them have focused only on bulk-scale analysis. Without understanding these basic reactions at the nanoscale level, it will be difficult to achieve an effective breakthrough. In situ transmission electron microscopy (TEM) allows one to observe electrochemical phenomena at the nanoscale, enabling one to investigate basic reactions at the proper scale in real time. Today, I will present in-situ TEM techniques dedicated to the field of electrochemistry.
