Solar module prices reached a new low this week, says Leen van Bellen, business development manager Europe for Search4Solar, a European purchasing and selling platform for solar products. He tells pv magazine that prices will remain low in the short term.
The case for an H2 economy is one entirely based on Green H2 made from surplus renewables which are needed most days to have enough renewable energy every day.
That gas companies know how to build pipelines, distribution, and make metered gas sales to customers is a path for them/employees to remain useful without destroying the planet.
Commercial vehicles has legitimate benefits of lower cost from H2 FCs than batteries. Quicker refuel times. Aviation especially benefits from redesigning planes for H2 for the weight savings. Trains/ships need the power/range. Trucks/cars can use the range extension, and could use H2 as removable auxiliary power for extended range.
Those vehicles can also charge the grid, and as hybrids, EVs or grid can be charged from static H2 FCs. For building energy, a FC can provide the usual fraction of domestic hot water from its waste heat. The electric monopoly problem is an opportunity for both producers and consumers to bypass their high rates and fees. Ammonia and fertilizer is traditional use for H2. There needs to be a carbon tax to move away from giant fosil H2 plants powering next door giant ammonia/fertilizer plants.
Hydrogen electrolysis is just one form of electro chemistry. Other fertilizers can be made from simpler versions of the process. It’s not so much that H2 is essential in unlimited quantities, it is that electro chemistry is possible ultra cheaply when there is an abundance of renewables that provides enough energy every day to power their locality. H2 is special as a chemical for being transportable/convertable as mobile or other elecricity/heat.
