Hybrid vehicles are already big business from hybrid cars, buses and trucks to outdoor forklifts, even hybrid tugboats.

About $160 million has been invested in graphene companies, excluding government and IPO financing. Companies continue to move up the value chain, from selling graphene to selling graphene based intermediary products such as inks - a welcome development from end users as it lifts their burden of fine tuning and experimentation.

At the start, there was no generic name. The simple glass of the car windshield started to incorporate printed antennas and heaters. It was what we now know as "structural electronics" - one structure performing mechanical, electrical and other functions.

Launches of fuel cell cars are reportedly planned by up to six carmakers from 2015 including Tata Motors of India, owners of Jaguar Land Rover.

It is not much of an achievement to make a fuel cell powered vehicle any more. They have been made for over 25 years and they work well.

A revolution is slicing through the car industry.

In 2025 over $25 billion will be spent on formulations and intermediate materials for wearable technology, as forecast by analysts IDTechEx in the brand new report Wearable Technology Materials 2015-2025.

Thermoelectric harvesting will be on production hybrid electric on-road vehicles from 2018. It will be commonplace on hybrids in 2020 and almost entirely to charge the battery, or increasingly supercapacitor or supercabattery used for power.

Load bearing structures that are also electronic or electrical are called structural electronics. This two-for-the-price-of-one approach can be more reliable, attractive and long-lived and it always saves space.

The market for hybrid and pure electric cars homologated as such is set to be $188 billion in 2025 according to IDTechEx analysis.

First was the significant investment from the materials community but now the equipment industry has turned its attention to printed electronics as a growth opportunity.

Electric and hybrid vehicles for construction, agriculture and mining will be a $30 billion market in 2025.

Structural electronics (SE) is one of the most important emerging technologies in this century.

Form factor is becoming a major driver shaping innovation and transforming the energy storage industry globally.

Electronics embedded within the structure of bridges, walkways, EVs, aircraft and more, have the potential to be a $60 billion market by 2025.

The event Hybrid and Electric Vehicle Forum consisted a conference with about 70 delegates and a small display area for a few organisations. Here we give some details of the presentations that particularly caught our attention.

The Reed Exhibitions event last week consisting of PV Expo, Battery Osaka and Smart Grid Expo successfully extended an event that started with photovoltaics last year.

Graphene electrodes are one of the best prospects for enabling supercapacitors and superbatteries to take up to half of the lithium-ion battery market in 15 years - amounting to tens of billions of dollars yearly.

Graphene could radically improve batteries and supercapacitors as explained in the new IDTechEx report Functional Materials for Supercapacitors/Ultracapacitors/EDLC 2015-2025.

The replacement of batteries means grabbing a chunk of the lithium-ion battery market in particular but also inroads into lead-acid and nickel metal hydride territory.
