                      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.},
