Perovskite Solar Cell Record 23.9% Efficiency

perovskite breakthrough

Perovskite breakthrough may fast-track new solar PV technology

The Belgium IMEC research center developed a new Perovskite solar cell with a conversion efficiency of 23.9%.

According to IMEC this is even more than the conventional silicon solar cells.

This new step is promissing. Even without Perovskites, the cost of solar power is already competitive with fossil fuels in some markets.

If and when this new innovation breaks through commercially, costs will drop even further.

GreenBattery replaces dirty generators

GreenBattery replaces diesel generator

Per battery system we decrease the consumption of 62,000 liters of diesel and 159,000 kg of CO2-emissions per year!

Is the GreenBattery of replacing the polluting and noisy (diesel) generators at festivals and construction sites?

Nuon and StartUp GreenBattery think the battery capacity should be sufficient.

They are going to let the Green Battery to festival organizations and local governments.

The batteries are half a large shipping container and will be charged with solar and wind power.

Can Hydrogen compete E-cars?

Can Hydrogen Cars compete with E-cars?

In the body of the study it becomes clear that FCVs do not beat internal combustion engines (ICEs) by much in equivalent fuel economy, And they are not much better in greenhouse gas emissions either, particularly in the liquid hydrogen versions, because of the energy required to transport and compress the hydrogen.

Hydrogen fuel cell cars appear to be making a comeback. But is this real? The comparison in question includes discussion of:

  • the wider process behind producing hydrogen fuel
  • the production itself
  • the compression/storage
  • the transportation of the fuel
  • associated factors

The future is a bit cloudy for hydrogen fuel cells (HFC), as electric vehicles have developed quickly and taken significant market share. Read More

SheerWind Invelox windtube

SheerWind Invelox windtube

This system of capturing, concentrating, accelerating, and harvesting wind power in a funnel is a patented system we call INVELOX™

The SheerWind technology seems to be a cost-effective, high-performance alternative to conventional wind technology. Look at this trending new wind turbine. 

According to Dr. Daryoush Allaei, founder of SheerWind, the industry is looking at the problem the wrong way.

Current wind turbines are really only an optimized step beyond the old sail based windmills of Europe, passively waiting for the appropriate wind. Read More

The Maglev train travels 4,000 miles/hour

This Maglev train reaches a speed of 4,000 miles/hour. Perfect for international traveling

Speed in initial ET3 systems is 600km/h (370 mph) for in state trips, and will be developed to 6,500 km/h (4,000 mph) for international travel

The Maglev train uses magnets for propulsion.

It is fully suspended by a magnetic field and requires less than 2% of the energy planes use.

The train has no wheels, so nothing can wear up. Read More

Wind Power Hub North Sea

Wind Power Hub North Sea

TenneT’s thinking is based on an island with a modular structure, with each module covering approximately 6 km². This is big enough to provide space for connecting roughly 30 GW of offshore wind capacity. The island will be expandable by adding one or two modules of 6 km² each

An Energy Hub in the middle of the North Sea? Tennet launched a vision building an island as a hub, for wind power in the middle of the North Sea which will provide all neighboring countries green energy.

By connecting wind farms with a total capacity of over 30 gigawatts, the efficiency and costs will benefit the participating countries.

This plan was presented by TenneT last week. TenneT is the national high-voltage grid operator in the Netherlands and in a part of Germany. Read More

Portugal 72 hours on renewables

Portugal 72 hours on renewables

Last week the German government reported that the Portugal produced so much renewable energy on a particularly sunny, windy Sunday that there was a power surplus.

In may 2016, Portugal ran for more than half a week without having to resort to fossil fuels.
Thanks to a big push toward solar, wind, and hydro power and a little nudge from the EU, for four days, Portugal produced enough clean, sustainable electricity to meet the needs of its people. Read More

Dubai Plans $7.3 Billion Renewable Energy Tenders

Dubai Electricity and Water Authority has announced a comprehensive plan to significantly increase investment in renewable energy projects.

Announcing its annual budget, the Dubai Electricity and Water Authority (DEWA) stated that it will float tenders worth Dh 27 billion (US$7.35 billion) to set up renewable energy projects. The projects are expected to be commissioned through the independent power producers model.

The Authority did not give any details for the likely renewable energy projects that will be pursued. However, among the largest tenders would be for the next phase of the Mohammed bin Rashid Al Maktoum solar power park.

The first large phase of the solar park, with 200 MW capacity, is being constructed by ACWA Power-led consortium. Another tender for 800 MW capacity has attracted interest from global project developers, and the winner of this phase is expected to be announced soon.

DEWA plans to increase the total capacity of the solar park to 3 GW by 2030, so a number of tenders are expected to be issued. The Authority is expected to develop other renewable energy and clean energy projects.

Dubai has set a target to increase the share of renewable energy in its total energy mix to 7% by 2020. The medium-term and long-term targets for renewable energy share are 25% by 2030 and 75% by 2050.

Yesterday, US Secretary of State John Kerry announced a doubling of the US payments on climate aid from 430 to $ 860 million in 2020. With this gesture of goodwill the White House hopes for a possible signal from the developing countries.

Yesterday, the new concept agreement was finished. Just two hours later than promised.

  • It is 29 pages shorter than the previous one (43)
  • More than three quarters of the discussion have been resolved.
  • The choices are reduced from 200 to 40

1.5 degree is only feasible if we take CO2 from the air and store it underground. Alternatives to remain at 1.5 degree are no longer realistic.

While the political will is increased to limit the global warming at 1.5 degrees, scientists point on the technical challenge.

CO2 storage is needed and the world must be fossil free by 2030, say scientists.

At an event on the sidelines of the climate summit, focussing on CO2 emissions in 2015, scientists are warning 1.5 degrees warming will be difficult. Read More
