Arkup, the “avant-garde life on water” company, has designed a new luxury home that integrates solar on the roof and a newly approved lithium ion marine battery system. The main selling features are that it can rise with sea levels via jacks, withstand extreme weather, move as a regular electric propelled boat, and provide it’s own water plus – of course – electricity.

In Tesla’s Q3 2017 earnings report, they gave an update on their ‘Tesla Energy’ division. They highlighted being on track to meet the 100-day deployment deadline of the 100MW/129MWh energy storage project for South Australia. Mention was made of the work being done in Puerto Rico in the aftermath of Hurricane Maria – ‘solar panels, Powerpacks and hundreds of PowerWalls.’

Additionally, Tesla – at multiple points – pointed toward a future of more revenue from energy generation and storage. 11% of the quarter’s revenue came from the Tesla Energy division.

Electrical grid complexity has increased immensely. Recently, weather damage and intermittent renewable energy production have increased the dynamics that must be managed in a large power grid. In order to address that, the Dutch company Alfen is currently field testing their new ‘cellular smart grid’ solution in Lelystad, the Netherlands.

They have developed a combination of energy storage and finely tuned algorithms to help make electrical grids more resilient and to reduce their downtime.

Four Swiss universities came together to build the US Department of Energy’s 2017 Solar Decathlon overall winner. Eleven teams competed over the course of two years to build a home taking into account modern global demands of “reliability, resilience, and security.”

The Swiss schools – École Polytechnique Fédérale de Lausanne, School of Engineering and Architecture Fribourg, Geneva University of Art and Design, and the University of Fribourg – scored perfect 100’s in energy, architecture and engineering categories.

Reality is, that most people who want solar power on their home actually want energy storage as well. We want energy storage because if the grid goes down, we want our house to run smoothly – day or not, sunny or cloudy. Additionally, many of us hold onto the dream of disconnecting from The Man.

At SolarPower International 2017 it was clear that the solar+energy storage hardware market – SolarEdgeSonnenBYD, Kehua, Outback, Hauwei, Schneider and others – are almost ready (or in terms of Sonnen/SolarEdge/Schneider – ready today) to serve the home energy demands of the broader population.

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

Amish phone booths – McKenna trained a local high-school physics teacher to do installations. About 50 of them are off the grid. One lights up the gazebo in the local cemetery; others are phone booths meant especially for the Amish. Since religious principle dictates no electricity at home, they rely on the booths as a crucial link to the outside world.  The article is really about solar power in Trump voting areas, but the Amish piece caught my attention. Solving problems with solar.

Most energy industry watchers saw the growth of energy storage to be inevitable in order to support renewable energy growth and to stabilize the grid, but deployment had been slow until now.

Several new projects coming online during the first quarter 2017 made it the first significant deployment of energy storage in the US to date: 234 megawatt-hours of energy storage. expand full story

New NREL report details installed costs and deployment barriers for residential solar+storage – If you really want to do some research on what your battery system is going to cost, and why, start here. NREL reports are always top notch – I distribute them often (and maybe some of you should download this stuff before Pruitt deletes it).

South Australia getting 100MW energy storage plus 330MW of solar – Is 100MW the largest battery system connected to a power grid? How do they go from announced last night to built before end of year? Or that’s right – solar + storage. And, most interestingly, it isn’t Elon Musk doing the deal. These Australians move fast when the electricity stops running.

As I reported on the new offshore wind strategy by the United States yesterday, Scotland was busy welcoming the beginning phase of the world’s first, and largest underwater tidal energy farm which will be placed off the north coast of Scotland. The first out of the four planned turbines sits at a height of 49 ft, 53 ft in diameter and over 40,000 lbs with a capacity of 1.5 megawatts (MW).

On Sunday, Scotland produced 106% of its electricity needs -over a 24 hour period – via wind farms. Scotland joins a select group of countries that have had peak moments (or days/months/forever) when their electricity needs comes from non-polluting renewable energy. Iceland runs completely on hydroelectric and geothermalCosta Rica ran for 75 straight days in 2015, Portugal ran for four days, Denmark generated 140% of their demand, Germany broke 95% for a few moments and there are many other countries with wonderful clean energy achievements. With places like Hawaii aiming for 100%, Rhode Island building its first off shore wind farm and the US Department of energy readying the mainland’s grid to be able to handle 100% – we will see reports like this proliferate in the future.
