Even though storing intermittent wind and solar power in electric car batteries sounds attractive, this will be impractical and expensive in practice, writes Schalk Cloete. Electric cars have much clearer synergies with baseload power plants, while excess wind and solar power is better suited to H2/synfuel production. … [Read more...]
Energiewende enters a new phase – how is it performing?
The Energiewende is proceeding ahead of schedule with high grid reliability, writes researcher Schalk Cloete. However, costs are much higher than originally planned, while CO2emissions are stagnating. According to Cloete, wind/solar market shares have now reached the point where large grid expansion projects become critical. One problem is that the net value of new wind/solar is approaching zero as market value declines and integration costs … [Read more...]
A common goal for all sustainability advocates
Nothing is better for fossil fuel interests than current government policies supporting wind, solar and electric cars, writes independent researcher Schalk Cloete. These green technologies won't reduce fossil fuel consumption sufficiently for a long time to come, so the fossil fuel sector will be able to survive that much longer. In the third and last part of a series on green technology-forcing, Cloete calls on all sustainability advocates to … [Read more...]
The plethora of better alternatives to wind and solar power and electric cars
Technology neutrality can activate more than ten times greater sustainable development potential than current technology-forcing policies, writes independent researcher Schalk Cloete. In the second part of a series which follows an article about the dangers of technology-forcing of wind and solar power and battery electric vehicles, Cloete reviews eight alternative sustainable development solutions that he believes have greater climate mitigation … [Read more...]
The dangers of green technology-forcing
Current technology-forcing policies imply that wind and solar power, combined with battery electric vehicles, represent our only viable energy future, observes independent researcher Schalk Cloete. Given the fundamental limitations of these technologies, this is a very dangerous notion, he argues. A shift to technology-neutral policies is needed, especially in developing nations. … [Read more...]
Beyond oil: options for clean fuel production
Several options exist for clean fuel production in the long-term future, writes Schalk Cloete in the third and last part of a series on the future of the internal combustion engine. Next-gen biofuels have the potential to approach current oil prices at a low environmental cost. Hydrogen can be produced economically from excess wind/solar power, nuclear heat or fossil fuels with CCS. Ammonia and hydrocarbon synfuels from clean hydrogen can be … [Read more...]
The future for gas guzzlers lies in hybridization
The car of the future will be a hybrid, writes independent researcher Schalk Cloete in the second part of a short series in which he compares costs and performance of various drivetrains. According to Cloete, improvements and cost reductions in electric motors and batteries will, ironically, help the internal combustion engine (ICE) through hybridization. These cost reductions combined with substantial engine downsizing can make hybrid … [Read more...]
