Hydrogen remains one of the most exciting applications of clean , renewable energy. Its production has been demonstrated on an industrial scale. Today the price of hydrogen is at an all time low of about $5/kg. That's a kilogram of fuel for about the price of a cold brew coffee. Yet green hydrogen has not been as successful as other fuels or alternative clean energy technologies like batteries. This was among the main points of discussion at the conferences I attended in New Delhi and those organised online by Society for Automotive Engineers (SAE) in the USA. One of the most important reasons for slow adoption of green hydrogen is simply the fierce competition it faces from Non Renewable fuels that are so cheap that it makes even a small price of $5/Kg look expensive. One solution was proposed during the presentation of GenH2 where they suggested using decommissioned oil wells to produce H2 in situ using gasification (a combination of water gas reforming a...
This summer I had the opportunity to meet Candace Johnson, a pioneer in space communication systems. She co-founded and grew SES (Société Européenne des Satellites) into one of the largest satellite fleets in the world. SES is significant because it represents one of the early attempts at privitisation of the space sector along with Intelsat. Prior to this space was exclusively controlled by the government and was confined to mostly research and military operations. Led By Candace SES provided Direct To Home satellite and radio broadcast services that democratised information access to millions of citizens in Europe and in the rest of the world. Listening to her speak about how this sector evolved and broke free from the control of the government I was able to connect the dots on how telecommunication became the primary business model of the space industry. Historically speaking the evolution of satellites from the initial Low earth orbits to medium earth and geo...
