Only in Japan, vehicle-to-grid integration

A few weeks ago, lots of Americans were left without power for days after a violent storm moved from the Midwest to the Mid-Atlantic. In Japan, this blackout wouldn’t have happened since they created a new technology that allows you to power your home by using your car.

This technology is an all electric Leaf that can integrate into your home’s energy supply. So simply put, your car can power your home and your home can power your car. This sound very futuristic and it must be said that this can’t be bought anywhere else but in Ginza, a shopping district in the heart of Tokyo. Customers looking to buy a car can buy this Leaf with Nissan dealers.

Ken Screbnik, Vice President for strategic planning and business development for Nissan, said that depending on the size of your home, the power from your car can be used to power your home for about two days. So things can keep running when there’s a power disruption.

In terms of energy management, this Leaf to Home system is a game changer and it’s also an industry first. All customers need to do is buy this Leaf and they become their own energy supplier. They even can get paid to store energy.

An EV power station unit, similar in size to an external air conditioning unit, allows the power to move through the house and be stored in the Leaf’s battery so it can be sent in to the home. It charges your car in four hours and sells for about £2.440. When users generate their own electricity from wind or solar stations, they can store the excess power in the car’s battery. So it reduces the owner’s bills.

After last year’s tsunami and earthquake-triggered nuclear disaster, Japan started to create a vision for smarter energy systems, and this vehicle-to-grid system is part of this vision. After the devastation last year, there was no way to get gas to gas stations and the view on electric vehicles totally changed. They were still able to work and they realized how comfortable the backup energy storage system is. Screbnik said that they were able to work with the government to provide subsides and shape a business out of these tragic events.

Since the disasters, the Japanese Government want to make sure that there is a stable power supply at any time. That’s a reason why they are so interested in the Smart City concept, promising cleaner energy integration, the ability for cities to maintain their own energy supply and so on. About 50 Smart City projects are already proposed in Japan.

Kashiwa-no-ha, one of the Smart cities just outside of Tokyo, began construction smart grids before the disasters last year and they should be finished in 2014. The 26.000 people that will be living in the city by then will have access to smart grid features like the ability to monitor and control their own energy supply with mobile application. Ai Kanda, Communications Officer for Kashiwa-no-ha said that they are offering one of the most innovative smart grid projects in the world. Citizens will be able to conserve 40 percent of energy.

America is also up to date when it comes to Smart Cities, they rank amongst the top investors of smart grid investments worldwide. The Departments of Energy (DOE) already invested about 3.4 billion dollars in about 100 smart grid projects throughout the nation. Some leading cities are San Diego, Boulder, Colo and Westerville Ohio.

But they are lagging behind when it comes to vehicle-to-grid integration. Jim Northrup, Vice President for power and energy at SAIC, said that the U.S. will start with more fleet-sized vehicles and predicts that within the next five years, America will see commercial vehicle-to-grid integration. But it will take about 10 years for residential vehicle-to-grid integration.

SAIC and the Department of Defense are working together to launch one of the first vehicle-to-grid pilot projects in the US at the Schofield Barracks in Hawaii. The project is called the Aloha Microgrid Project and it’s part of the Defense Department’s larger efforts to move to electric cars.

Europe’s Smart City Initiative

Last year, Europe has set up an Initiative on Smart Cities. The Initiative fosters the dissemination throughout Europe of the most efficient models and strategies to progress towards a low carbon future. European countries should be progressing towards the energy and climate objectives at a local level while maintaining or improving the quality of live. Investments in energy efficiency and reduction of carbon emission can be used to improve local economies.

The Initiative wants a 40% reduction of greenhouse gas emissions by 2020 (with start year 1990), which is very ambitious. This reductions can be obtained by using and producing sustainable energy. The Initiative will support cities and regions in creating a systematic approach and organizational innovation to encompass energy efficiency, low carbon technologies and the smart management of supply and demand. The main components of the Initiative is the measures of buildings, local energy networks and transport. Local authorities have to propose and implement holistic problem-solving approaches that use appropriate technology and policy measures.

Things that have to been done is for example the refurbishment of existing buildings so they use as less energy as possible while increasing performances and comfort. A good example of these sort of buildings are passive buildings, using vacuum insulation, windows, cool roofs,… New buildings have to be build with zero energy requirements or net zero carbon emissions.

In terms of energy, smart grids, smart meters, energy management systems, smart appliances and equipments can be used. And when thinking about transport, we think about sustainable mobility. Advanced smart public transport, intelligent traffic management and more encouragements to walk and cycle.

And all these objectives have to be turned into actions. The Initiative helps with this according to a city’s ambitions and the risk that’s involved. So ambitious cities could get funding for technical assistance to facilitate access to loans and risk sharing loans. And pioneer cities, taking much greater risks because they use radical technology and organizational transformations, could in addition receive grants to support the implementation of the proposed package of technologies and measures.
