As a clean yet effective energy source, hydrogen can be used to not only power vehicles on the road and in the air, but also propel vessels on the water and deep below the surface. So far, however, attempts to design a fuel cell vessel for travelling on rivers, lakes and oceans have been few and far between. Even though no such ship has made it onto the market yet, it’s not as if the maritime industry cannot point to many years of developing alternative systems. (more…)
The aviation industry is aiming for carbon-neutral growth starting in 2020 and a CO2 reduction of 50 per cent by 2050 compared to 2005 [1]. There are currently two options under discussion to achieve these goals: Emission certificates and biofuels. Both are not immune to criticism because of their direct and indirect impact on the environment. (more…)
The energy transformation needs efficient storage solutions and technologies for heat conversion. One of the institutions playing an important role in advancing the transformation of the energy sector is the Fraunhofer Institute for Solar Energy Systems, ISE, in Freiburg. Increasing interest in energy storage technologies as well as efficient heating and cooling processes has led to an expansion of ISE’s (more…)
